Lisa Hatfield:
Dr. Chen, can you provide an overview of your research focus around improving treatments and cure rates for patients facing an aggressive prostate cancer diagnosis? And also, two parts to this question. What inspired you to focus on the topic of health equity in relation to prostate cancer?
Dr. Ronald Chen:
Well, in terms of thinking about my research on improving treatments for advanced prostate cancer, and I’ll just define that to say, advanced prostate cancer, we usually think of as patients who have prostate cancer that has spread to other parts of the body. And so that’s often very aggressive. And, of course, in that situation, there’s still a lot of room for us to improve treatment so we can extend the survival and also improve the quality of life for these patients as much as we can. So a lot of room for improvement. And really, I think how we get to that improvement is mostly through clinical trials.
There’s a lot of promising new treatments that are more effective in tackling the cancer that also potentially can improve the patient’s quality of life, which is also a very important situation for advanced prostate cancer. And so a lot of my research really focuses on clinical trials to incorporate new treatments or new ways to do treatment for patients with advanced prostate cancer.
I’ll give one example. I lead a national trial that’s sponsored by the National Cancer Institute. It’s called NRG-GU008. We call it the INNOVATE trial. And this trial is specifically for patients who have prostate cancer that has spread to the lymph nodes. And if you have prostate cancer that has spread to the lymph nodes, that’s technically stage IV. And we, again, don’t do as well as we want to for these patients. And what this trial is testing is standard of care which would involve radiation and hormone therapy compared to standard of care, radiation/hormone therapy, plus a new drug that seems to hold promise for prostate cancer.
And, of course, we’re testing to see whether adding this new drug would reduce further spread of the cancer, improve survival, and how it impacts quality of life. And so, that’s a very important effort for no positive prostate cancer patients. And we are trying to enroll almost 600 patients, and so far we’re about 200 patients into it. So it’s an ongoing trial. It’s open across the country. And I really do hope that at the end of this trial, we’ll be able to offer a new option for these patients.
I’m involved in other trials around the country that are testing other treatments for advanced prostate cancer. And a lot of my focus on these other trials is also to sort of assess the impact of these treatments on the patient’s quality of life. I think quality of life is really important. We don’t just want to focus on being more aggressive and more aggressive and more aggressive without accounting for how the aggressive treatment really impacts a patient, how their quality of life is and side effects. And so that’s also another really important focus of my research and clinical trials.
In terms of my focus on health equity, health equity is a really important topic because even though we have pretty good treatment for prostate cancer, we know that not all patients have the same access to treatment, and not all patients have the same outcome with advanced prostate cancer. And so, studying why there is a disparity where some patient groups don’t do as well. We know for a fact that based on multiple studies, that Black patients with prostate cancer are more likely to die from prostate cancer twice as much as white patients with prostate cancer.
So we want to understand why, and once we understand why, we want to design interventions to reduce that gap, so then all patients have the same access and have good outcomes with this disease. And so I think that relates to access to screening. So we can diagnose cancer as early as we can. It relates to access to clinical trials, and that’s another really important aspect of my research focus.

Establishing Treatment Goals: What Are Options for Advanced Prostate Cancer Therapy? |
Transcript:
Katherine:
This actually leads me to my next question which is about research news.
Prostate cancer research is evolving quickly, like so many other cancers. And it’s important for patients to stay up to date on developing news. So, are there research advances that patients should be aware of?
Dr. Gao:
Yeah, I mean some of the treatments that I just mentioned, PARP inhibitors, pembrolizumab (Keytruda) for MSI higher and mismatch repair deficient tumors and lutetium. Those have come out of recent major clinical trials and have become the standard of care in a lot of different…in various different settings for patients. And there are always new research trials, clinical trials, that are going to either move some of these established treatments to earlier lines of setting, earlier lines of treatment, or using them in maybe combination with other drugs where we might learn that they’re more useful if we combine it with another drug or maybe combine it with hormone treatments earlier rather than later.
So, there are always clinical trials for advanced prostate cancer. There are even newer trials, novel therapies, completely new treatments that have been studied in the laboratory in say petri dish models of cancer or animal, mouse models of prostate cancer, but have shown enough early exciting data to try to move them into human beings and hopefully help advanced prostate cancer patients.
Katherine:
As we wrap up, Dr. Gao, I’d like to get your thoughts. How do you feel about where we stand with advanced prostate cancer care?
Dr. Gao:
Yeah. I think there have been a lot of advances in advanced prostate cancer care in recent years. Newer and better treatment strategies seem to come along every couple of years, and I think what we’ve seen for advanced prostate cancer patients over the past, really, since probably 2015 or so, is a significant improvement in outcomes, long-term outcomes like survival and slowing down of the cancer.
And it’s…I think it’s important to acknowledge that and to acknowledge that the clinical trials in recent years have really led to a lot of improvements and really the hope that in the coming years, there’s going to be additional research, additional clinical trials, newer treatments hopefully, that will continue to improve outcomes for advanced prostate cancer patients. I also think that it’s really critical to evaluate the specific patients’ cancer characteristics, things like the genetic testing that I mentioned earlier, as well as their sort of life situations and other medical comorbidities to come to a shared decision about what makes the most sense in terms of their cancer management.
Genetic testing might open up the option for certain FDA-approved therapies or consideration of certain targeted therapies that still might be in clinical trials. And clinical trials, again, are also an option for additional treatment strategies that otherwise would not be available.

Hello, and welcome. I’m Katherine Banwell. Your host. Today’s program focuses on helping patients with advanced prostate cancer insist on better care. We’re going to discuss the latest research, current treatments, and how patients can collaborate with their healthcare team on key decisions.
Before we meet our guest, let’s review a few important details. The reminder email you received about this program contains a link to program materials. If you haven’t already, click that link to access information to follow along during the webinar.
At the end of this program, you’ll receive another link to a program survey. Please take a moment to provide feedback about your experience today, in order to help us plan future webinars. And finally, before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you.
Well, let’s meet our guest today. Joining me is Dr. Channing Paller. Dr. Paller, welcome. Would you please introduce yourself?
Dr. Paller:
Thank you, Katherine. I’m delighted to be here today. My name is Channing Paller. I’m Associate Professor of Oncology at Johns Hopkins and the director of Prostate Cancer Clinical Research.
Katherine:
Thank you so much for taking the time to join us today.
Dr. Paller:
Thank you for having me.
Katherine:
Dr. Paller, in June, prostate cancer researchers from around the world met to discuss their findings at the annual American Society of Clinical Oncology, or ASCO meeting, in Chicago. Would you walk us through the highlights from that meeting that patients should know about?
Dr. Paller:
Absolutely. We’ve had a exciting time for prostate cancer in June. So, I’d say, the first thing I would bring up is, the PEACE-1 trial was discussed again, and more data came out from that trial. That trial originally supported what we found, the STAMPEDE trial, to say, yes, we should add abiraterone to androgen deprivation therapy and chemotherapy in helping de novo metastatic patients live longer and do better overall. And it also, this time around, showed us that combining abiraterone (Zytiga) with radiation, plus or minus chemo, had patients do better. So, they had a longer progression-free survival, or metastasis-free survival.
And also, the neat thing was, patients had fewer local symptoms in the long run. So, it prevented catheters being needed later, prevented blockages. It prevented local side effects from their cancer, which was really terrific to know, because that helps with patients’ quality of life.
That was one of the main, personally. Go ahead.
Katherine:
Yeah, I was just going to ask, anything else?
Dr. Paller:
Yes. So, the second big headline, which is one of my dear loves, is all of the PARP inhibitor data. So, there were a couple trials presented, and this month has been terrific in terms of, there have been two drug approvals. So, let me talk through a couple of those.
So, one of the big ones that was presented at ASCO was looking at talazoparib (Talzenna) and enzalutamide (Xtandi) in patients with metastatic castration-resistant prostate cancer, and it showed that the combination of those two drugs helped patients do better than enzalutamide alone, in that setting. What was also interesting is a subset of patients with DNA repair mutations did even better.
June 20th, the FDA approved that combination for patients with metastatic castration-resistant prostate cancer with DNA repair mutations.
We also had a drug approval for abiraterone (Zytiga) and olaparib (Lynparza) in the same space of metastatic castration-resistant prostate cancer for patients with BRCA mutations. That was a more narrow approval, but it was still very important.
And what’s exciting here is, we’re really learning more about targeted therapy, precision medicine, for our prostate cancer patients. When I started treating prostate cancer patients back in 2005, the main drug approved was chemotherapy, docetaxel (Taxotere), and hormone deprivation therapy. And in the last almost 20 years, or 18 years, we’ve had 10 drug approvals, and we’re really starting to have multiple drugs approved based on people’s genetics.
Katherine:
That’s such promising news. I mentioned at the top of the program that our focus for this webinar is advanced prostate cancer. So, I’d like you to define that. What is advanced prostate cancer? And is any of the research you mentioned focused on this stage of disease?
Dr. Paller:
Well, advanced prostate cancer includes any prostate cancer that was extended outside the prostate, really, that’s spread to the nodes, even to the lymph nodes, to the liver, to the lungs, to the bones. And so, we have a lot of new findings, looking at this space, and that was a lot of what they showed at the ASCO conference.
The other thing we’re learning is that we really want to get genetic testing on everybody. And so, in addition to your regular, “How do you feel?” “What do your labs show?” “What is your PSA doing?”
We also want to get imaging, right? So, we want to look at imaging, in terms of, what did your CT and bone scan show? And nowadays, we’re moving into PSMA, or prostate-specific membrane antigen, PET scans.
And so, that’s the new main way people look at where their prostate cancer has gone, and help them decide, what is the best treatment for me? Is it to get surgery locally, or has it advanced now, and I really need to do hormone therapy and radiation, or some other combination of systemic therapy, meaning more hormones, or more chemotherapy, with targeted therapies such as radiation?
Katherine:
Beyond ASCO, Dr. Paller, are there other research or treatment advances that patients should know about? Anything other than what you’ve mentioned already?
Dr. Paller:
Oh, yes. So, the other headline that I was really excited about at ASCO is watching medicine adopt the world of artificial intelligence. There was a great abstract, looking at how we can use artificial intelligence to look up pathology slides.
So, in the past, we would always want to go to a top academic center to have your pathology reviewed by a top expert and make sure we were treating the right cancer, and make sure we really understand your risk. What we’re finding is, we can create biomarkers, and we’re understanding not just genetic, genomic biomarkers, but also pathology biomarkers, and age, and PSA, and risk, and comorbidities, and we can combine them all together and use AI to help us better stratify patients.
And so, although it’s early, I think this is going to be an explosion in terms of helping us better define risk for patients in advanced prostate cancer, and help them figure out, do they need intensification of treatment, or can we de-intensify treatment? Can we not cause as much toxicity, and they’ll do just as well? And so, I was really excited to see that data as well.
Katherine:
How can patients stay up to date on evolving research?
Dr. Paller:
There are many ways to stay up to date. There are nice summaries at ASCO. There are nice summaries through the Prostate Cancer Foundation. There are good summaries at each of the institutions with whom you work.
One of my favorite ways to stay up to date on precision medicine is one of these registries that I am co-leading, which is called the PROMISE registry. This is a wonderful opportunity which was conceived in the pandemic.
And so, it’s pandemic friendly, and that is called the PROMISE registry. And what you can do is go to prostatecancerpromise.org and sign up if you have prostate cancer. And you say, “Hey, I have prostate cancer. This is my address. Please ship me a kit where I can do saliva testing of my genes.” And once you get your tests sent in, they’ll send you a kit, you send it back, you’ll get an email, and you can go over your results with a genetic counselor.
And then, once you get enrolled in this program, it is really just a free information source. And so, you can learn more about the clinical trials around the country for patients with different mutations. And so, I love that as, whether or not you have a mutation and you’re going to follow with us for 20 years, because we’re going to offer you opportunities and let you be the first to know about new drug approvals, you can still hear about all of the new research.
And I think that’s a wonderful, free resource that we’ve done for our patients to help them understand more about what’s out there. Another opportunity to learn more about prostate cancer is the prostate cancer clinical trial consortium. They have a nice website looking at germline genetics, looking at diversity, looking about clinical trial design. And so, there’s lots of different places to learn more about prostate cancer.
Katherine:
Dr. Paller, what about clinical trials? Why should patients consider enrolling, and what are the benefits for them?
Dr. Paller:
I like to tell my patients that once you have metastatic or advanced prostate cancer, we’re not doing placebo on you. If we’re doing placebo, it’s the standard of care plus a new drug, and we want to know if the new drug in combination with the old drug is better than the old drug alone.
And so, I find those patients heroes, in one sense, for the future, right? They’re helping to approve the new drugs of the future, and I also find, oftentimes, those are the patients that do best, because they’re getting to try all of the new drugs of the future before they’re approved. And so, I will have patients that are, I call them chronic trialists because they’ll go through all my new drugs before they’re even approved.
And I love it, and they love it, because they do better than the average, because they’re exploring all of the new therapies. And so, I find those patients heroes, and I really appreciate their efforts. I would say, the most important thing about clinical trials is learning about them, right? And being able to ask the questions. “Well, what phase is that trial?” So, Phase I is really testing safety, and finding the right dose for patients. And so, that’s usually a small number of patients, and looking exactly at, does this work? Do we have a biomarker to follow? What’s the best way to use this new drug?
Phase II starts to look at efficacy, as well as looking at side effects. And so, with Phase II, we really look at, what is the effect? Is it better than what we expected? Does it help these patients – is it better than some of the other drugs?
And then, Phase III are usually large trials that are looking at FDA approval. They’re looking for registration with the FDA, getting approval, and being the new standard of care that’s paid for by insurance companies.
Katherine:
I’d like to back up a bit and talk about the treatments that are currently available. Let’s start with surgery. What role does that play in treating advanced disease?
Dr. Paller:
Surgery is one of the key tools that we use when we’re trying to cure prostate cancer when it’s localized, or just starting to spread. But if it’s too advanced, meaning, spreading to the lymph nodes, we usually don’t recommend surgery. So, surgery is usually used for curative intents, although there is a trial ongoing now, looking at the same question of, is adding surgery to systemic therapy helpful in terms of long-term cure rate, in terms of decreased side effects later, and local symptoms later?
And so, we are asking that question. That is one of the ongoing clinical trials that we’re looking at right now, as a group.
Surgery is terrific. Radiation is terrific. Really working with your team to understand for you, what are the side effects that you would undergo? What are the risks and benefits of each modality that you would like to, or that you’re willing to tolerate? And so, I think the differences between surgery and radiation, for curing patients, are really something that you need to discuss with your provider. The risk of erectile dysfunction, the risk of the local symptoms from the radiation, the risk of having bleeding from your bladder, the risk of bowel problems. Those are all things that that you – urinary incontinence – that you need to discuss with your physician.
Katherine:
What are other options that are available now, for patients?
Dr. Paller:
For curative intent, the main two treatment options are surgery, radiation. Many people for very localized disease are trying other therapies, such as cryotherapy, and more focal therapies. But really, for curative, the standard is surgery or radiation. And as it gets more advanced, circling back to advanced prostate cancer, we are learning that combination therapy is better. So, adding pills like abiraterone, adding systemic therapies, help patients do better.
So, there’s a big, long list of therapies upfront that we use for metastatic hormone-sensitive prostate cancer. There’s abiraterone, there is apalutamide (Erleada), there’s enzalutamide, and now, darolutamide (Nubeqa).
And in fact, in fit patients that can tolerate chemotherapy for metastatic high-volume prostate cancer patients, we always recommend triple therapy, either with abiraterone, docetaxel, and ADT, or with darolutamide, docetaxel, and ADT, and these patients really seem to do better for longer. The other thing I would add is the PEACE-1 trial, which looked at abiraterone and docetaxel, found that patients would do best by adding growth factor support. And so, that is recommended.
The other thing I want to point out to patients is, I know we’re all eager to get started when we find out we have a diagnosis of metastatic prostate cancer, but sometimes, these therapies are quite tough on the system when you have a lot of cancer in your body, and my recommendation to everybody is, one thing at a time.
So, start the hormone therapy and wait at least 30 days, and in fact, in the PEACE-1 trial, they waited 45 days, right? That allows the testosterone levels to fall, it allows you to adjust to the side effects of hormone deprivation therapy, and it allows your body to be ready for the next line of therapy. And you can add the ADT to second line, such as abiraterone or daro during that time, but not adding the chemo all at once, that really makes a difference.
I find, unfortunately, when patients and their providers don’t follow those strict criteria, as they did in the trial, meaning they start chemo and abiraterone and ADT on day one, the levels of chemotherapy get higher in the bloodstream because testosterone regulates that, and we’ve published on that before. And they end up with terrible side effects from the chemotherapy, such as neutropenic fever, which means you end up in the hospital with a bloodstream infection and a fever, and more neuropathy, meaning numbness and tingling in your hands and feet.
And so, I really caution people to spread those therapies out over the first 90 days, and you’ll do better in terms of side effects, and just as well in terms of overall survival.
Katherine:
Where does hormonal therapy fit into the treatment options, and have there been any advances in hormonal therapy?
Dr. Paller:
Yes. So, hormonal therapy is the mainstay of how we take care of prostate cancer patients, whether we do this with surgical castration, which is not done very often anymore, or we do it with an LHRH agonist, or we do it with an LHRH antagonist. So, that means that we can do it with medicines that block the signaling, but that tells your body to produce testosterone in various ways. What’s really neat is we’ve made advances, that there are now oral options for some of these therapies.
In particular, there’s a new therapy called Orgovyx, or relugolix, that is an oral LHRH antagonist that locks testosterone and allows us to stop prostate cancer growth. In addition, there are a variety of LHRH agonists that can be given as subcutaneous shots.
Katherine:
Dr. Paller, let’s talk about what goes into deciding on a treatment path. First, what testing helps you understand the patient’s individual disease?
Dr. Paller:
Great question.
When I meet a patient, we talked about a few variables. First is, how do they feel? Are they in pain? Are they losing weight? Are they fatigued all the time? Are they able to do things that they enjoy, or not? So, that’s the most important, in terms of, how do they feel, and what are their symptoms?
The next thing we looked at is, what are their labs, right? We look at PSA, but we also look at, is the prostate cancer affecting their organs? Is it affecting their red blood cells, their platelets, their white blood cells? And very importantly, it tells us, by looking at their alkaline phosphatase, if it’s in their bones or not. And we also can look at their labs to see, is it affecting their liver or not. Another thing we monitor is their creatinine or kidney function. Is there a blockage of their important organs down there because the prostate cancer has grown? So, the labs tell me a lot about their body function, and making sure their body is still functioning well.
After we do how they feel, and what their labs are, we also look at imaging. And then, the previous years, we’ve always looked at a standard nuclear medicine bone scan, and also, a CAT scan. And nowadays, we’re really moving towards PSMA, or prostate specific membrane antigen, to help us really identify, at a much more sensitive level, where prostate cancer cells are expressed.
And after we do those main three key things, we start to look at diagnostic tests. We look at different ways of assessing what are their genes. So, one of the first things we do is looking at germline genetic testing to see, what were the genes they were born with? And can those genes help us learn more about their cancer, and how it might progress? And also, how we might treat it better if they have certain genes like BRCA.
The other nice thing about genetic testing, or germline genetic testing, is looking at, if they do have a genetic mutation, or a pathologic variant like BRCA, we are always, always telling families that they should get cascade testing for their familyright? So, if they have a mutation, we recommend that their family members get tested to make sure that they’re not at risk for a cancer. And so, we have them meet with a genetic counselor.
So, in addition to what you’re born with, we also want to know what your cancer has developed, because cancer cells are growing quickly, and they can develop a mutation. And so, we also test the cancer, get genomic testing of the cancer, to look for mutations that we can target with our multiple drugs that we’ve approved to target cancers in certain mutations. So, you have something called MSII, we have immunotherapy for you. If you have DNA repair mutations, we have PARP inhibitors for you, or even carboplatin (Paraplatin) can be added to target patients with DNA repair mutations as well.
And so, there’s a whole variety of tests out there by a multitude of providers, that help us really better understand your cancer.
Katherine:
And the treatment options, by the sounds of it.
Dr. Paller:
And the treatment options. Yes, there is. There’s a whole variety of it. Yeah.
Katherine:
So, what is personalized medicine, Dr. Paller? And how is it achieved?
Dr. Paller:
Personalized medicine means many things to many different people. I find the most important thing is not forgetting the patient. The patient needs to be their own advocate, and have an advocate there with them, right? Because maybe the best treatment is chemotherapy, hormone therapy, radiation, etc., etc., but maybe you’re 92, and you’ve lived a good life, and you have heart disease, and you might not die of your prostate cancer. And so, overtreating people is just as dangerous as undertreating people.
And so, precision medicine is a whole variety of things, of looking at the whole person, looking at their genes, looking at biomarkers their cancers produce, and looking at what comorbidities they have, right? If you have really bad diabetes, maybe you don’t want me to add steroids to your regimen. If you have a seizure disorder, maybe you don’t want me to add insulin. I wouldn’t, because there’s a seizure risk. If you have various problems, we just need to take those into account and find the best therapy for each individual.
Katherine:
I think you’ve covered this, in a sense, but I’m going to ask you the question anyway. Why is it important that patients have a role in making decisions about their care?
Dr. Paller:
It is essential that patients have a role in their care so that they are taking ownership and being part of the team, to care for themselves, not to put extra weight or work on the patient, but really, so that they know they’ve made the right choice for them.
Understanding a patient’s priorities are essential. Some patients may not want the side effects of hormone therapy, and they may say, “Hey, I have oligometastatic disease, meaning I just have one spot to my bones, and I’m 80 years old. And Dr. Paller told me that the sub analysis of this triple therapy, new trial, showed that, I’m over 75, I may not benefit as much. And you know what? I don’t want to have the side effects of hormone therapy. I don’t want to lose muscle mass. I don’t want to have hot flashes. I don’t want to have erectile dysfunction.”
“I want to enjoy my life, even if it’s slightly shorter, and it might not be slightly shorter.” And so, I find, having a partnership with a patient to really understand their priorities makes life worth living more, right? So, maybe a patient’s priority is finding time with their grandchildren. Maybe a patient’s priority is getting a PhD. Whatever their patient’s priority is, it is important that we put that to the context of their whole being and helping them really find the best therapy for them, to help them do as well as they can, as long as they can.
Katherine:
I think this this leads us very nicely into the next topic, and that’s self-advocacy. While the goal of this program is to help patients insist on better care, there may be factors that impact their access. What common obstacles do patients face?
Dr. Paller:
The main obstacle for patients is insurance. Unfortunately, I find that it’s frustrating to not be able to provide patients with oral hormonal therapy if they can’t afford it, because they don’t have insurance, and it’s too expensive. But there are other challenges that patients face, right? If they’re young and don’t have childcare, if they have trouble getting time off their work. But I think one of the major problems is economics, and can they get the same care, and can they advocate for themselves, right? So, another problem is, if you are in a community practice, you might not have access to the top diagnostic testing.
And it’s really important that you advocate for yourself and get a second opinion at an academic center where you can get the best testing and figure out the best path for yourself. And sometimes, if patients are at sites where they’re seeing a generalist, they’re not going to get access to that, because that’s not standard at that hospital.
Katherine:
Yeah. Well, what is the medical community doing to help improve access?
Dr. Paller:
We are working hard on reaching out into the community. One of the other hats I wear is, I’m Associate Program Director for the Johns Hopkins Clinical Research Network for oncology. And one of my jobs is to find communities that want to open trials at community sites.
These aren’t our super complicated phase I trials. These are often simple Phase II or Phase III trials that patients can participate in, and really get access to new biomarker tests, get access to new treatments, and really be connected to the centralized knowledge that is available at academic centers.
And I think all of ASCO is doing this, I think all the Prostate Cancer Consortium is doing that, I think the PCF is doing this, and we really are – and I even think the drug companies are reaching out and educating primary care doctors, urologists, radiation oncologist patients.
There are a lot of programs we now do that are direct to patient education, so that we’re not dependent on whether or not the doctor has time to explain these things. And so, programs like this are really wonderful at keeping the patients educated and able to advocate for themselves.
Katherine:
What diversity in clinical trials? Is that an emphasis for the research community?
Dr. Paller:
Absolutely. I think that’s an emphasis across the board in society today.
We are eager to learn more about how patients with different genetic profiles, with different ethnicities, with different socioeconomic backgrounds, are reacting differently to different therapies. If you’re African American, do you respond differently to [treatment] with one study we looked at? If you have a different diet, are you going to respond differently to immunotherapy? And really understanding different demographics is really important to us at this time.
Katherine:
Are there resources that patients can turn to that would help them gain better access to healthcare?
Dr. Paller:
There are programs that are available either through your local community, or another one that has a nice patient centered education program is NCCN, or the National Comprehensive Cancer Network. They have summaries of your tumor type across the board, and how to best treat it.
They also have a list of experts that helped make those guidelines, so that you could reach out to those centers and know the main centers that are treating your cancer.
Katherine:
That’s great advice. Thank you. If a patient is feeling like they aren’t getting the best care, though, what steps should they take to change that?
Dr. Paller:
That’s a good question. So, being a self-advocate takes energy, when oftentimes, you’re tired and overwhelmed at your cancer diagnosis. And so, my heart goes out to all of those patients. Really, finding a second opinion, and finding an academic center or a large program that has a prostate cancer focused program, is helpful.
Or whatever your tumor or issue is, going to a center that is a specialist in that, for a second opinion, is often helpful, and can work with your local physician to help get you the care that you need.
Katherine:
That’s great information, Dr. Paller. Thank you. As we wrap up, I’d like to get your closing thoughts. How do you feel about the future of prostate cancer care? Are you hopeful? Encouraged?
Dr. Paller:
I am so hopeful and encouraged. We are exploding in the number of drugs we have. We are exploding in the number of opportunities and precision medicine drugs that we’re having. This is a wonderful time where we’re combining our understanding of genetics, and biomarkers, and AI, and pathology, and imaging, and I am thrilled.
I think we’re really going to be able to understand which patients should get which drugs without having so much toxicity. And such a high failure rate here, or how do I know who will get the best treatment?
“We’re just going to try it and see.” I don’t want to have to say that in five years. I want to say, “I know this will work, and I can control your symptoms and your side effects.”
And so, I am so excited about the future. I think we’re just making huge strides every day now, and I think this will be a whole new world in the next five years.

Advanced Prostate Cancer: How to Access the Best Care and Treatment for YOU |
Transcript:
Katherine:
What are other options that are available now, for patients?
Dr. Paller:
For curative intent, the main two treatment options are surgery, radiation. Many people for very localized disease are trying other therapies, such as cryotherapy, and more focal therapies. But really, for curative, the standard is surgery or radiation. And as it gets more advanced, circling back to advanced prostate cancer, we are learning that combination therapy is better. So, adding pills like abiraterone, adding systemic therapies, help patients do better.
So, there’s a big, long list of therapies upfront that we use for metastatic hormone-sensitive prostate cancer. There’s abiraterone, there is apalutamide (Erleada), there’s enzalutamide, and now, darolutamide (Nubeqa).
And in fact, in fit patients that can tolerate chemotherapy for metastatic high-volume prostate cancer patients, we always recommend triple therapy, either with abiraterone, docetaxel, and ADT, or with darolutamide, docetaxel, and ADT, and these patients really seem to do better for longer. The other thing I would add is the PEACE-1 trial, which looked at abiraterone and docetaxel, found that patients would do best by adding growth factor support. And so, that is recommended.
The other thing I want to point out to patients is, I know we’re all eager to get started when we find out we have a diagnosis of metastatic prostate cancer, but sometimes, these therapies are quite tough on the system when you have a lot of cancer in your body, and my recommendation to everybody is, one thing at a time.
So, start the hormone therapy and wait at least 30 days, and in fact, in the PEACE-1 trial, they waited 45 days, right? That allows the testosterone levels to fall, it allows you to adjust to the side effects of hormone deprivation therapy, and it allows your body to be ready for the next line of therapy. And you can add the ADT to second line, such as abiraterone or daro during that time, but not adding the chemo all at once, that really makes a difference.
I find, unfortunately, when patients and their providers don’t follow those strict criteria, as they did in the trial, meaning they start chemo and abiraterone and ADT on day one, the levels of chemotherapy get higher in the bloodstream because testosterone regulates that, and we’ve published on that before. And they end up with terrible side effects from the chemotherapy, such as neutropenic fever, which means you end up in the hospital with a bloodstream infection and a fever, and more neuropathy, meaning numbness and tingling in your hands and feet.
And so, I really caution people to spread those therapies out over the first 90 days, and you’ll do better in terms of side effects, and just as well in terms of overall survival.
Katherine:
Where does hormonal therapy fit into the treatment options, and have there been any advances in hormonal therapy?
Dr. Paller:
Yes. So, hormonal therapy is the mainstay of how we take care of prostate cancer patients, whether we do this with surgical castration, which is not done very often anymore, or we do it with an LHRH agonist, or we do it with an LHRH antagonist. So, that means that we can do it with medicines that block the signaling, but that tells your body to produce testosterone in various ways. What’s really neat is we’ve made advances, that there are now oral options for some of these therapies.
In particular, there’s a new therapy called Orgovyx, or relugolix, that is an oral LHRH antagonist that locks testosterone and allows us to stop prostate cancer growth. In addition, there are a variety of LHRH agonists that can be given as subcutaneous shots.

Katherine:
Dr. Paller, let’s talk about what goes into deciding on a treatment path. First, what testing helps you understand the patient’s individual disease?
Dr. Paller:
Great question.
When I meet a patient, we talked about a few variables. First is, how do they feel? Are they in pain? Are they losing weight? Are they fatigued all the time? Are they able to do things that they enjoy, or not? So, that’s the most important, in terms of, how do they feel, and what are their symptoms?
The next thing we looked at is, what are their labs, right? We look at PSA, but we also look at, is the prostate cancer affecting their organs? Is it affecting their red blood cells, their platelets, their white blood cells? And very importantly, it tells us, by looking at their alkaline phosphatase, if it’s in their bones or not. And we also can look at their labs to see, is it affecting their liver or not. Another thing we monitor is their creatinine or kidney function. Is there a blockage of their important organs down there because the prostate cancer has grown? So, the labs tell me a lot about their body function, and making sure their body is still functioning well.
After we do how they feel, and what their labs are, we also look at imaging. And then, the previous years, we’ve always looked at a standard nuclear medicine bone scan, and also, a CAT scan. And nowadays, we’re really moving towards PSMA, or prostate specific membrane antigen, to help us really identify, at a much more sensitive level, where prostate cancer cells are expressed.
And after we do those main three key things, we start to look at diagnostic tests. We look at different ways of assessing what are their genes. So, one of the first things we do is looking at germline genetic testing to see, what were the genes they were born with? And can those genes help us learn more about their cancer, and how it might progress? And also, how we might treat it better if they have certain genes like BRCA.
The other nice thing about genetic testing, or germline genetic testing, is looking at, if they do have a genetic mutation, or a pathologic variant like BRCA, we are always, always telling families that they should get cascade testing for their family, right? So, if they have a mutation, we recommend that their family members get tested to make sure that they’re not at risk for a cancer. And so, we have them meet with a genetic counselor.
So, in addition to what you’re born with, we also want to know what your cancer has developed, because cancer cells are growing quickly, and they can develop a mutation. And so, we also test the cancer, get genomic testing of the cancer, to look for mutations that we can target with our multiple drugs that we’ve approved to target cancers in certain mutations. So, you have something called MSII, we have immunotherapy for you. If you have DNA repair mutations, we have PARP inhibitors for you, or even carboplatin (Paraplatin) can be added to target patients with DNA repair mutations as well.
And so, there’s a whole variety of tests out there by a multitude of providers, that help us really better understand your cancer.
Katherine:
And the treatment options, by the sounds of it.
Dr. Paller:
And the treatment options. Yes, there is. There’s a whole variety of it. Yeah.
Katherine:
So, what is personalized medicine, Dr. Paller? And how is it achieved?
Dr. Paller:
Personalized medicine means many things to many different people. I find the most important thing is not forgetting the patient. The patient needs to be their own advocate, and have an advocate there with them, right? Because maybe the best treatment is chemotherapy, hormone therapy, radiation, etc., etc., but maybe you’re 92, and you’ve lived a good life, and you have heart disease, and you might not die of your prostate cancer. And so, overtreating people is just as dangerous as undertreating people.
And so, precision medicine is a whole variety of things, of looking at the whole person, looking at their genes, looking at biomarkers their cancers produce, and looking at what comorbidities they have, right? If you have really bad diabetes, maybe you don’t want me to add steroids to your regimen. If you have a seizure disorder, maybe you don’t want me to add insulin. I wouldn’t, because there’s a seizure risk. If you have various problems, we just need to take those into account and find the best therapy for each individual.
Katherine:
I think you’ve covered this, in a sense, but I’m going to ask you the question anyway. Why is it important that patients have a role in making decisions about their care?
Dr. Paller:
Patients are different, just like everybody – let me start over.
It is essential that patients have a role in their care so that they are taking ownership and being part of the team, to care for themselves, not to put extra weight or work on the patient, but really, so that they know they’ve made the right choice for them.
Understanding a patient’s priorities are essential. Some patients may not want the side effects of hormone therapy, and they may say, “Hey, I have oligometastatic disease, meaning I just have one spot to my bones, and I’m 80 years old. And Dr. Paller told me that the sub analysis of this triple therapy, new trial, showed that, I’m over 75, I may not benefit as much. And you know what? I don’t want to have the side effects of hormone therapy. I don’t want to lose muscle mass. I don’t want to have hot flashes. I don’t want to have erectile dysfunction.”
“I want to enjoy my life, even if it’s slightly shorter, and it might not be slightly shorter.” And so, I find, having a partnership with a patient to really understand their priorities makes life worth living more, right? So, maybe a patient’s priority is finding time with their grandchildren. Maybe a patient’s priority is getting a PhD. Whatever their patient’s priority is, it is important that we put that to the context of their whole being and helping them really find the best therapy for them, to help them do as well as they can, as long as they can.

Why Prostate Cancer Patients Should Consider Participating in a Clinical Trial |
Transcript:
Katherine:
Dr. Paller, what about clinical trials? Why should patients consider enrolling, and what are the benefits for them?
Dr. Paller:
I like to tell my patients that once you have metastatic or advanced prostate cancer, we’re not doing placebo on you. If we’re doing placebo, it’s the standard of care plus a new drug, and we want to know if the new drug in combination with the old drug is better than the old drug alone.
And so, I find those patients heroes, in one sense, for the future, right? They’re helping to approve the new drugs of the future, and I also find, oftentimes, those are the patients that do best, because they’re getting to try all of the new drugs of the future before they’re approved. And so, I will have patients that are, I call them chronic trialists because they’ll go through all my new drugs before they’re even approved.
And I love it, and they love it, because they do better than the average, because they’re exploring all of the new therapies. And so, I find those patients heroes, and I really appreciate their efforts. I would say, the most important thing about clinical trials is learning about them, right? And being able to ask the questions. “Well, what phase is that trial?” So, Phase I is really testing safety, and finding the right dose for patients. And so, that’s usually a small number of patients, and looking exactly at, does this work? Do we have a biomarker to follow? What’s the best way to use this new drug?
Phase II starts to look at efficacy, as well as looking at side effects. And so, with Phase II, we really look at, what is the effect? Is it better than what we expected? Does it help these patients – is it better than some of the other drugs?
And then, Phase III are usually large trials that are looking at FDA approval. They’re looking for registration with the FDA, getting approval, and being the new standard of care that’s paid for by insurance companies.
Katherine:
I’d like to back up a bit and talk about the treatments that are currently available. Let’s start with surgery. What role does that play in treating advanced disease?
Dr. Paller:
Surgery is one of the key tools that we use when we’re trying to cure prostate cancer when it’s localized, or just starting to spread. But if it’s too advanced, meaning, spreading to the lymph nodes, we usually don’t recommend surgery. So, surgery is usually used for curative intents, although there is a trial ongoing now, looking at the same question of, is adding surgery to systemic therapy helpful in terms of long-term cure rate, in terms of decreased side effects later, and local symptoms later?
And so, we are asking that question. That is one of the ongoing clinical trials that we’re looking at right now, as a group.
Surgery is terrific. Radiation is terrific. Really working with your team to understand for you, what are the side effects that you would undergo? What are the risks and benefits of each modality that you would like to, or that you’re willing to tolerate? And so, I think the differences between surgery and radiation, for curing patients, are really something that you need to discuss with your provider. The risk of erectile dysfunction, the risk of the local symptoms from the radiation, the risk of having bleeding from your bladder, the risk of bowel problems. Those are all things that that you – urinary incontinence – that you need to discuss with your physician.

Transcript:
Katherine:
Dr. Paller, in June, prostate cancer researchers from around the world met to discuss their findings at the annual American Society of Clinical Oncology, or ASCO meeting, in Chicago. Would you walk us through the highlights from that meeting that patients should know about?
Dr. Paller:
Absolutely.
We’ve had a exciting time for prostate cancer in June. So, I’d say, the first thing I would bring up is, the PEACE-1 trial was discussed again, and more data came out from that trial. That trial originally supported what we found, the STAMPEDE trial, to say, yes, we should add abiraterone (Zytiga) to androgen deprivation therapy and chemotherapy in helping de novo metastatic patients live longer and do better overall. And it also, this time around, showed us that combining abiraterone with radiation, plus or minus chemo, had patients do better. So, they had a longer progression-free survival, or metastasis-free survival.
And also, the neat thing was, patients had fewer local symptoms in the long run. So, it prevented catheters being needed later, prevented blockages. It prevented local side effects from their cancer, which was really terrific to know, because that helps with patients’ quality of life.
That was one of the main, personally. Go ahead.
Katherine:
Yeah, I was just going to ask, anything else?
Dr. Paller:
Yes. So, the second big headline, which is one of my dear loves, is all of the PARP inhibitor data. So, there were a couple trials presented, and this month has been terrific in terms of, there have been two drug approvals. So, let me talk through a couple of those.
So, one of the big ones that was presented at ASCO was looking at talazoparib (Talzenna) and enzalutamide (Xtandi) in patients with metastatic castration-resistant prostate cancer, and it showed that the combination of those two drugs helped patients do better than enzalutamide alone, in that setting. What was also interesting is a subset of patients with DNA repair mutations did even better.
June 20th, the FDA approved that combination for patients with metastatic castration-resistant prostate cancer with DNA repair mutations. (Lynparza) in the same space of metastatic castration-resistant prostate cancer for patients with BRCA mutations. That was a more narrow approval, but it was still very important.
And what’s exciting here is, we’re really learning more about targeted therapy, precision medicine, for our prostate cancer patients. When I started treating prostate cancer patients back in 2005, the main drug approved was chemotherapy, docetaxel (Taxotere), and hormone deprivation therapy. And in the last almost 20 years, or 18 years, we’ve had 10 drug approvals, and we’re really starting to have multiple drugs approved based on people’s genetics.
Katherine:
What is advanced prostate cancer? And is any of the research you mentioned focused on this stage of disease?
Dr. Paller:
Well, advanced prostate cancer includes any prostate cancer that was extended outside the prostate, really, that’s spread to the nodes, even to the lymph nodes, to the liver, to the lungs, to the bones. And so, we have a lot of new findings, looking at this space, and that was a lot of what they showed at the ASCO conference.
The other thing we’re learning is that we really want to get genetic testing on everybody. And so, in addition to your regular, “How do you feel?” “What do your labs show?” “What is your PSA doing?”
We also want to get imaging, right? So, we want to look at imaging, in terms of, what did your CT and bone scan show? And nowadays, we’re moving into PSMA, or prostate-specific membrane antigen, PET scans.
And so, that’s the new main way people look at where their prostate cancer has gone, and help them decide, what is the best treatment for me? Is it to get surgery locally, or has it advanced now, and I really need to do hormone therapy and radiation, or some other combination of systemic therapy, meaning more hormones, or more chemotherapy, with targeted therapies such as radiation?
Katherine:
Beyond ASCO, Dr. Paller, are there other research or treatment advances that patients should know about? Anything other than what you’ve mentioned already?
Dr. Paller:
Oh, yes. So, the other headline that I was really excited about at ASCO is watching medicine adopt the world of artificial intelligence. There was a great abstract, looking at how we can use artificial intelligence to look up pathology slides.
So, in the past, we would always want to go to a top academic center to have your pathology reviewed by a top expert and make sure we were treating the right cancer, and make sure we really understand your risk. What we’re finding is, we can create biomarkers, and we’re understanding not just genetic, genomic biomarkers, but also pathology biomarkers, and age, and PSA, and risk, and comorbidities, and we can combine them all together and use AI to help us better stratify patients.
And so, although it’s early, I think this is going to be an explosion in terms of helping us better define risk for patients in advanced prostate cancer, and help them figure out, do they need intensification of treatment, or can we de-intensify treatment? Can we not cause as much toxicity, and they’ll do just as well? And so, I was really excited to see that data as well.
Katherine:
How can patients stay up to date on evolving research?
Dr. Paller:
There are many ways to stay up to date. There are nice summaries at ASCO. There are nice summaries through the Prostate Cancer Foundation. There are good summaries at each of the institutions with whom you work.
One of my favorite ways to stay up to date on precision medicine is one of these registries that I am co-leading, which is called the PROMISE registry. This is a wonderful opportunity which was conceived in the pandemic.
And so, it’s pandemic friendly, and that is called the PROMISE registry. And what you can do is go to prostatecancerpromise.org and sign up if you have prostate cancer. And you say, “Hey, I have prostate cancer. This is my address. Please ship me a kit where I can do saliva testing of my genes.” And once you get your tests sent in, they’ll send you a kit, you send it back, you’ll get an email, and you can go over your results with a genetic counselor.
And then, once you get enrolled in this program, it is really just a free information source. And so, you can learn more about the clinical trials around the country for patients with different mutations. And so, I love that as, whether or not you have a mutation and you’re going to follow with us for 20 years, because we’re going to offer you opportunities and let you be the first to know about new drug approvals, you can still hear about all of the new research.
And I think that’s a wonderful, free resource that we’ve done for our patients to help them understand more about what’s out there. Another opportunity to learn more about prostate cancer is the prostate cancer clinical trial consortium. They have a nice website looking at germline genetics, looking at diversity, looking about clinical trial design. And so, there’s lots of different places to learn more about prostate cancer.

Expert Perspective on the Future of Prostate Cancer Treatment and Research |
Why Prostate Cancer Patients Should Consider Participating in a Clinical Trial |
Transcript:
Katherine:
Dr. Wise, is there developing research or treatment news that prostate cancer patients should know about?
Dr. David Wise:
Yeah. I think in terms of other research, I think where we’re seeing a lot of excitement is in boosting the treatment at the time of initial diagnosis for men with metastatic prostate cancer, right?
So, what we’ve found is that for prostate cancer – and this has been true for some other cancers, but not all – it seem that when we use our best treatments early, we get a greater and greater return. We get a greater and greater durability of our effect and a more prolonged benefit of treatment effectiveness, of quality-of-life preservation, and a life span. That has really been, I would say, one of the key take-home points from the last five years.
And so, what’s exciting in the field is that we’re continuing to go in that direction. So, for example, there are clinical trials now testing some of the new CDK4/6 inhibitors like abemaciclib or Verzenio, which is a clinical trial that we have here for men who are initially diagnosed.
There are clinical trials testing lutetium PSMA 617 at the time of the initial diagnosis rather than waiting until treatment resistance develops. I think it’s a principle that’s emerged. I don’t know that I would call it a law. If it were, we wouldn’t have to do clinical trials, and that’s because with more exposure to these treatments, there is potential for more cumulative side effects with more combinations of treatments. There’s more potential for additive side effects that can occur from that combination.
So, we need to see and really prove to ourselves that treating earlier is better than treating in a one-treatment-at-a-time sequential approach. But I think that the lesson from many other cancers has really been that combination treatments have been the most effective treatments. And I think that now that we have additional effective treatments that have been approved as a standalone strategy.
What’s exciting now is that we’re now seeing the combination of these strategies into one, two, three, four drug regimens. And can we cure? And that’s, of course, what we’re really hoping for. That’s what we’re all striving for in oncology. So, that’s, I think, were a lot of the excitement is in oncology right now.

Tools for Choosing the Right Prostate Cancer Treatment Approach |
Transcript:
Katherine:
I’d like to begin with an update on prostate cancer research. Would you walk us through the newer classes of treatments that are showing promise?
Dr. Subudhi:
Yeah, in clinical trials, there are classes of drugs known as androgen receptor degraders. And so, the androgen receptor is a protein that basically is the mouth of the prostate cancer. That’s how I like to describe it. And it actually allows testosterone, which is the food, to be eaten by the mouth, and it actually helps the cancer grow.
And what these drugs do is they actually degrade or break down the mouth of the cancer. And, therefore, it starves the cancer to death, and that’s actually the concept. And they seem to be showing some exciting activity in clinical trials, especially in those patients who are resistant to the second-generation hormonal drug that you may have heard of already, such as enzalutamide (Xtandi), apalutamide (Erleada), and darolutamide (Nubeqa). So, I think is something that we’re looking forward to seeing more data on.
Another class of drugs are antibody drug conjugates or ADCs.
And these are what I think of as heat-seeking missiles. So, one part of the drug actually recognizes the cancer, and the other part of the drug actually has a payload that sort of releases a bomb or sort of like chemotherapy-type agent right where the cancer’s located and kills the cancer in that way. And we’re seeing some great clinical activity in prostate cancer with this class of drugs.
And then the final one is bispecifics, and in particular T-cell bispecifics. So, T cells are part of the immune system that actually help kill the cancer.
And, unfortunately, prostate cancer, like some other cancers like pancreatic and glioblastoma, have few T cells inside it. And, therefore, a lot of the immunotherapies that many people have heard about, such as ipilimumab (Yervoy) and pembrolizumab (Keytruda), they’re not very responsive in patients with prostate cancer. And it’s because there’s few T cells in prostate cancer.
What the T-cell bispecifics do is they actually have one part of the drug that actually recognizes the cancer and the other part that recognizes T-cells. So, like a bulldozer, it brings T cells right into the prostate cancer and helps kill the cancer that way.
Katherine:
Now there are some inhibitors as well. Is that correct?
Dr. Subudhi:
Yeah. So, the immune checkpoint inhibitors have been around for a while. And, basically, in combination, they seem to be more effective in prostate cancer. But when given alone as monotherapy, they’re less effective.
Katherine:
Are these treatments specifically for patients with advanced prostate cancer?
Dr. Subudhi:
All of them are actually in trials in patients with advanced prostate cancer. And I define advanced prostate cancer as either having metastatic disease, meaning the cancer has spread to other parts of the body outside of the prostate.
Examples include lymph node, the bone, the lung, the liver. But there are so few trials in patients with locally advanced prostate cancer. What I mean by that is they have high-grade prostate cancer, but it’s local, or it’s just in regional lymph nodes. And some of these classes of drugs are being evaluated in that setting as well.
Katherine:
Let’s shift to talk about your research. What are you excited about right now?
Dr. Subudhi:
So, my research focuses on immune checkpoint therapies, which are the inhibitors that you were referring to and understanding how to make them work better in prostate cancer.
And we’re finding out that in prostate cancer there’s about 20 to 25 percent of patients that appear to respond to this type of treatment. But these are patients that don’t have a lot of bone metastases. And these immune checkpoint inhibitors are given in combination. So, they’re not given alone. They’re given with either a combination of anti-CD34 and anti-PD-1 or some other form of that.

Dr. Heather Cheng:
I think it’s a really exciting time. I think there are a lot of advancements throughout prostate cancer. I think one area of importance is early detection, but we also have newer imaging platforms, meaning the way, and we can discover where the prostate cancer is, is advancing through new types of PET scans that we didn’t previously have. And then my own kind of research which is near and dear to my heart is talking about genetics and what we have learned about the genetics of the risk of prostate cancer, but also how the genetics of the cancer itself, which sometimes is inherited, and sometimes isn’t can help us plan for better treatments for patients.

Katherine:
When it comes to prostate cancer research and emerging treatment options, what are you excited about specifically?
Dr. Beer:
Well, there is so much to talk about there. And I do want to say that the things that we’re excited about and that are promising, we want to present them in the proper light, meaning that they’re significant potential advances, but they’re not necessarily cures next year.
You know, we want to raise hopes and excitement at a proper level. So, I think right now, what we’re seeing is progress that is likely to yield drugs that will extend survival, will help us control the disease in a meaningful way. We’re not yet at a point where we can, for advanced prostate cancer, have a reasonable hope of cure in the near term. That doesn’t mean we’re not trying. We’re aiming high, absolutely.
But at the moment, the most exciting thing right in front of us, in my view, is lutetium 177-PSMA 617. That is a radioactive molecule attached to a binder that is specific to prostate-specific membrane antigen, PSMA, and essentially delivers this radioactive drug directly to prostate cancer cells by attaching to that target, the PSMA.
We recently completed and reported at ASCO and published in the New England Journal of Medicine the results of a Phase III trial, where we were able to show extension of life, extension of control of cancer, in a meaningful way, with this drug, and we’re eager to see the FDA’s review, and I think generally hopeful that the FDA will allow this drug on the market hopefully in the coming months. So, that’s a real tangible thing that is not just pie in the sky years away. I think it’s likely to be available sometime in less than a year, hopefully much less than a year. Speculating on those things is always a little risky, but –
Katherine:
Of course.
Dr. Beer:
– we all think that’s coming.
I think there are several other targeted drugs that may expand the portfolio of things that we can do in response to a mutational analysis. So, I mentioned microsatellite instability and DNA repair defects. There might be treatments for mutations in a pathway called AKT and others. And so, I think we’re going to see more very specific drugs that address segments of prostate cancer. And then a big area of activity that I’m very excited about is immunotherapy. And immunotherapy has been difficult in prostate cancer.
It has made more headway in melanoma and kidney cancer, and a number of other solid tumors, frankly, and we’re a little bit behind, and I think in part because natural prostate cancer doesn’t elicit quite as much of an immune response as some of the other tumor types; so, it’s not so easy.
But some of the newest technologies for synthetic antibodies are being designed that link the T cells from the immune system directly to prostate cancer cells and activate them, I think hold a lot of promise.
And ultimately, when it comes to cure, the immune system right now looks like the most promising strategy for actually eradicating cancer because once you activate the immune system, it can really do quite a job on cancer. Right now, for prostate cancer, that is still almost entirely in clinical trials and still for a minority of patients. So, this is not an answer for everybody, but once we get a hold of something that’s promising, I think the field’s going to work very hard to expand its utility and make it a reality for more and more patients.

Katherine:
Dr. Hussain, how do you feel about the future or prostate cancer research, and what would you like patients to know?
Dr. Hussain:
First, let me say that I would love for the patients to know that they are a partner, a most critical partner in the process.
That we need to continue the research and investment in research. It is research that will end up curing cancer. Wishful thinking will not do it. And patient volunteering, which I think is remarkable across all cancers. The business I’m in, the way that drug discovery and evolution often happen because patients volunteered. And without testing these new treatments and combinations, we will not be able to get better results.
And I will tell you that, when I started my training, the median survival for patients with resistant prostate cancer was on the magnitude of about nine months. Now it is three years-plus. Now, you could argue, well, that’s not huge. But that is a huge change because, again, we’re picking up the cancers much earlier. And the patients who had, as I mentioned, metastatic disease, again, the longevity then at the time I was in training, but even afterwards, was give and take in the three years. And now we’re talking six-plus years.
And so, there’s been tremendous progress. And really partnership with the patients and their families and supportive others is very critical, and investment in research. So, yes, advocate constantly for more investment in research.
