Transcript:

Katherine:

Well, let’s dive into developing research and what it could mean for patients. Are there recent research highlights that you could share with the audience?  

Dr. McKay:

Absolutely. I think the newest approvals that have occurred in prostate cancer have been the approvals of combination PARP inhibitors, which block the ability of cancer cells to repair their DNA combined with hormonal agents such as abiraterone (Zytiga) or enzalutamide (Xtandi) for patients who have specific mutations in their tumor and their tumor is no longer responding to treatment. Those are the newest FDA approvals that were recently highlighted and shared.  

Katherine:

What areas of research do you specialize in? 

Dr. McKay:

The areas of research that I specialize in are particularly around novel therapeutics for patients with advanced prostate cancer, biomarker development precision medicine strategies for patients across the spectrum. And actually, also, in the localized setting, thinking about how we can attempt to cure more patients with prostate cancer by integrating our systemic therapy with surgical and radiation strategies to improve survival outcomes for patients and ultimately, cure it for patients by using effective systemic therapy early on so patients never recur.   

Katherine:

We’ve been hearing a lot recently about innovations in technology. How are these advances accelerating prostate cancer care?  

Dr. McKay:

Innovations of technology have absolutely been revolutionizing prostate cancer care I think from the diagnostic side, there’s new imaging modalities that are getting more refined. On the molecular side, there’s now different kinds of genetic tests. And our ability for us to do these tests, and do them quickly, and get results in real time that we can make decisions on we’ve come a long way from when we first sequenced the human genome. We’re now able to do that so quickly multiple times over in a very streamlined kind of way. And then, I have to say that there’s been tremendous improvement in our modalities of administrating therapies.  

So, our therapies are getting more novel, they’re getting more precise. What I mean, by that is targeted radioligand therapy, targeting linking a small molecule that binds PSMA, labeling it with a payload that is radiation therapy or kind of radio therapy/radio particle doing the same thing with chemotherapy, developing antibody drug conjugates. There’s androgen receptor degraders. There’s different ways of administrating immunotherapy by specific antibodies. So, there’s just the different sorts of treatments that are out there.  

We’ve just come such a long way from hormone therapy, which is still very important in chemotherapy to other different modes of action with the different systemic treatments we have.  

Katherine:

What about individual patients? Is there research into understanding a person’s – just one person’s disease?  

Dr. McKay:

Absolutely. I mean, that is in essence, precision medicine. I think we are now molecularly profiling tumors that is standard of care for anybody with advanced disease to undergo hereditary tumor profiling and – or hereditary profiling of just normal cells in the body, if there’s any sort of genetic abnormalities. But also, the tumor itself, and able to do that all for the actual biopsy specimen, or surgical specimen, and also blood. And then, based off of that individual’s genetic makeup, or the genetic makeup of the tumor, or the immune profile of the tumor actually trying to target therapy.  

There is a clinical trial that we are eagerly developing through the alliance, which we hope will open to enrollment before the end of the year, called the PREDICT Study. And this study is using that very notion of taking somebody’s DNA and RNA from their specific tumor, and based off of their results, strategizing the treatment around what kind of genetic makeup is in the tumor. And I think we’re moving towards that.  

Katherine:

What about common genetic mutations and what are you learning about people who have other genetic mutations like the BRCA mutation?  

Dr. McKay:

For patients who have BRCA mutations, first I’ll say, the prevalence of BRCA mutations varies across the stage of prostate cancer that somebody has. In the localized setting, the prevalence is a lot lower on the order of 2 to 4 percent depending on somebody’s risk profile. In the advanced setting, it is higher, 6 to 8 percent. Patients who have BRCA alterations are particularly susceptible to PARP inhibitors, which are oral drugs that can be given that when given in an individual who’s got a BRCA mutation, can cause cell death; can cause a tumor cell to die. And so, that’s a very good thing.  

I think the other thing, if thinking about the type of BRCA alterations, if there’s something that’s hereditary, this information is prognostic and predictive in that in can guide how people are going to – how we think they may do and what they may respond to. But it’s also really important because it can inform cascade testing for family members. It could also inform screening for secondary cancers in that individual who has prostate cancer with a known BRCA alteration. So, I think there’s a lot of personalization that happens based off of the molecular profiling results.

Katherine:

Dr. McKay, I’d like to have you tell us how the landscape of advanced prostate cancer has changed over your career.  

Dr. McKay:

Oh, my goodness. It has absolutely rapidly evolved over the last decade. I think when I was just starting my career, it was right around the time where abiraterone (Zytiga) and enzalutamide (Xtandi) were being heavily tested and just getting approved and entering into the clinic.

And as we think about all of the evolution that’s happened since that time, we now have multiple androgen receptor pathway inhibitors in the clinic. We have radioligand therapies in the clinic, radium-223. The first radioligand therapy across any solid tumor malignancy to improve overall survival and on the heels of that, most recently, lutetium PSMA, which is a targeted radioligand therapy.

There are several different kinds of chemotherapies, and I think two more diagnostics have evolved. We are now integrating molecular profiling across multiple areas in the disease natural history and actually have several FDA-approved treatments based off of results of molecular profiling, whether that be germline hereditary testing or just tumor testing like, PARP inhibitors and immunotherapy.

And then, additionally, to kind of continue on that same thought of our diagnostics changing is one of the greatest disruptors in our treatment of prostate cancer has been the introduction of PSMA PET imaging that has really revolutionized our ability to be able to detect disease at lower levels of PSA.   

And that’s opened up options for focal therapy, radiation therapy, and other sorts of strategies. So, it’s really been just remarkable, all of the different advances that have occurred in prostate cancer over the last decade.

Lisa Hatfield:

Can you speak to the current treatment landscape and any new research coming out about advanced prostate cancer treatment that you are excited about? And how do you work with your patients to make treatment decisions, particularly those in underrepresented communities?

Dr. Yaw Nyame:

So, two very different questions. The first thing I’ll say is the landscape is changing, and there are a lot of exciting things. There are some trials that are showing that the combination of systemic therapies like the hormone blockade, whether it be hormone blockade at a large level, at the cell level with some of those novel agents like abiraterone (Zytiga) and enzalutamide (Xtandi) or even chemotherapy, how we combine those are all very exciting. But we also know that local control of the prostate, so either using radiation to the prostate, which was shown to be beneficial in a clinical trial from the UK called STAMPEDE, we have an ongoing clinical trial called SWOG 1802, which is looking at whether surgery locally to the prostate can add additional benefit to men with advanced prostate cancer.

So I think it’s exciting to understand how we can improve survival. It used to be around three-year survival for prostate cancer when you were diagnosed with advanced forms. We’ve moved that to beyond five years because of how many incredible new advances we have and these combinations of local therapy and systemic therapy. We also have new drugs coming into the landscape like lutetium Lu 177 vipivotide tetraxetan (Pluvicto), which is a PSMA tagged radioligand which has, you know, shown some really great results in the castration-resistant or hormone resistant space that’s being tested now earlier in the hormone sensitive space and high risk localized space.

So there are a lot of really fantastic and exciting new advances. I’m skipping over other types of medications that are really in the precision oncology space, like the PARP inhibitors which are shown to be beneficial in people who have, you know, certain genetic, you know mutations and DNA recombination.

So I think we continue to see evolution in this space where, you know, we used to sort of see this cancer as a one size fits all. And you know, we sort of try to sometimes hit a square peg into a round hole, and now we’re able to really say, okay, your cancer has these features and this combination of things is what’s going to work best. But the problem with that is the more nuanced and the more personalized our care gets, the more opportunity there is for people who are on the margins to be lost.

And so, you know, our historically, you know, marginalized and minoritized populations are sometimes going to be the ones at highest risk for not getting the latest and greatest. One of the things that I’m really interested in supporting and seeing supported in cancer centers and in clinical sites across the country is patient navigation.

Providing services that help people get connected to all the different types of doctors, all the different types of institutions that might offer them the treatments and the workups that they need to make sure that they get access to the best care that’s available. And that’s not only supporting the patient oftentimes, but that’s supporting their caregivers, their families, and making sure that what is a really complex process. It’s not just going in for one doctor’s visit oftentimes, right?

Seeing a lot of different specialists, getting a lot of different tests. But that process is supported for people that have especially among people that have significant social needs and may not be able to navigate that on their own. My activation tip in this space is to absolutely do your homework and find resources to help you navigate this very confusing and very busy landscape when you have your diagnosis.

A lot of cancer centers have patient navigators, okay? And if they don’t, they should. So that is one resource that you should not be afraid to ask for and utilize is someone from the doctor’s office. That’s just going to take the time to make sure if you need to be connected to an insurance, you know agency like Medicare or Medicaid, that you’re connected, that if there are certain appointments you need to make, that they help you schedule and if you need transportation support, that they help connect you to that. And so finding those resources, whether it’s through your community and peer network or through the cancer center, is really important to make sure that you can get as comprehensive of care as you can.

Sherea Cary:

My activation tip for care partners when addressing things like treatment and new research is for the care partner to be as informed as possible about other health issues that the patient may have, and to be transparent with the oncologist about what other things are going on in the patient’s life to make sure that they fit some of the new research that’s coming out or be able to, or the patient and the care partner are able to overcome those barriers that may separate them in some of the treatment decisions. 

Lisa Hatfield:

Right, thank you both Dr. Nyame and Sherea, who is a care partner. Thank you for that. Those activation tips.

Lisa Hatfield:

What is advanced hormone-sensitive prostate cancer, and are there specific symptoms or warning signs to be aware of?

Dr. Yaw Nyame:

When we have prostate cancer that has spread beyond the prostate. We define that as advanced or sometimes we call it metastatic prostate cancer. And early on in that process, we can control and often kill many of those prostate cancer cells by taking away testosterone. Testosterone ends up being like the fuel that allows these cancers to grow. And so when we say a prostate cancer is hormone-sensitive, what we mean is it’s sensitive to testosterone, and by shutting off testosterone, we can effectively manage and or kill those prostate cancer cells.

Over time, when we shut off that testosterone, prostate cancers will learn how to produce internally their own testosterone or develop resistance or find ways to still survive in the absence of testosterone, and when that happens, we call that pheromone-resistant or sometimes you will hear the term castrate-resistant prostate cancer.

Advanced prostate cancers are going to be in a category of cancers where people may have symptoms, those symptoms aren’t always specific, they can range from difficulty urinating, having blood in the urine, having fractures of bones that have been invaded with cancer, weight loss, loss of appetite, and so that is sort of a broad spectrum of symptoms that someone could potentially experience with an advanced prostate cancer, but not all folks are going to have those particular symptoms, because oftentimes when you have severe prostate cancer-related symptoms, those are in pretty advanced stages, meaning you have a pretty high amount of cancer that is outside of the prostate.

My activation tip, when it comes to hormone-sensitive prostate cancer that is advanced, is to be informed about the latest therapies that we offer in this space, because it is constantly changing 15 years ago. The mainstay of treatment was just hormone blockade, and we put people on medications that took their testosterone away or offered them surgeries to take away testosterone from the testicles. We then added on these novel testosterone or androgen-blocking medications like abiraterone (Zytiga) or enzalutamide (Xtandi), which people will hear about when they look up the space of what their diagnosis, then we added on chemotherapy in the form of docetaxel (Taxotere), and now we’re doing combinations where we add the hormone blockade and medicine like abiraterone and chemotherapy, what we call triplet therapy as now first-line therapy.

And so this space is changing so much that when you have this diagnosis, you need to take a pause and do your homework so that you are prepared to have a conversation with your medical oncologist about whether you need doublet therapy, one of the two medications or triplet therapy, or if you even need to consider the addition of something like radiation to the prostate. All of these are standard of care, and it’s no longer just a one medication pipeline for treatment is really an individualized and complex therapy.

Katherine:

Dr. Gao, now that we know what goes into understanding a patient’s disease, I’d like to talk about treatment, starting with treatment goals. How do goals vary by patient, if they vary at all? 

Dr. Gao:

Sure, yeah. I do think they vary, and I think it is important to be clear about what the realistic goals of treatment might be so that the patient can make an informed decision on how the prostate cancer should be treated or managed. 

Some prostate cancers are highly curable, although there isn’t anything that’s 100 percent, right? And others are curable, but we acknowledge that there may still be a significant risk of relapse despite treatment. And maybe that rough percentage, the probability of cure and sort of the potential downsides or side effects of treatment, that’s something that the patient has to weigh in terms of whether they want to proceed with that treatment or not.   

And then, there are cancers, especially with advanced prostate cancers, that are unfortunately not curable, but yet treatments have the ability to significantly prolong somebody’s life, to slow the cancer progression down or even to shrink it, and to improve cancer-associated symptoms and other sources of distress that we talked about earlier.  

And so, with each patient, I think it is important to talk about these treatment goals because it may not be readily clear, is this a curable cancer or not? And it might not be clear how much benefit they might expect with treatment or are we talking about a marginal benefit? And then that way, you know, they can think about it, talk about it with their family, and kind of factor into their overall benefit risk calculation about whether to do something or not. 

Katherine:

Would you provide an overview of current treatment options for advanced disease? 

Dr. Gao:

Sure. So, it’s a big, very open-ended question, I think.  

So, I think you can divide it up into sort of the major treatment modalities, so things like radiation or radiation types of therapies, chemotherapy, hormonal therapies which are the mainstay of prostate cancer treatments, targeted therapies, and immunotherapies.  

Starting with hormonal therapies which are the backbone of prostate cancer treatments, for advanced prostate cancer, androgen deprivation therapy or ADT is often given indefinitely as the typical standard of care treatment and there are various forms of ADT, most commonly in the form of long-lasting injectable medications – leuprolide (Eligard/Lupron Depot), goserelin (Zoladex), sometimes degarelix (Firmagaon)  is used. And then more recently, there was an FDA approval a couple years ago of an oral pill called relugolix (Orgovyx), which is also a form of ADT or androgen deprivation therapy.  

These medications block the body’s ability to make testosterone which is important for prostate cancer survival and spread. In addition, abiraterone is an oral medication that is also considered a hormonal therapy. It blocks the production on androgens or male sex hormones outside of the testes. That includes the adrenal glands and some other tissues such as prostate cancer itself. And abiraterone (Zytiga) is commonly used in advanced prostate cancer management, in addition to androgen deprivation therapy whereas ADT blocks the testes from making testosterone and androgens, abiraterone blocks the production of androgens outside of the testes.  

And then finally, oral anti-androgen medications that block the prostate cancers from being able to detect androgens or male hormones and to block the androgen receptors on prostate cancers from sending cellular signals for growth and survival are also very commonly used.  

There are older anti-androgen medications like bicalutamide (Casodex), flutamide (Eulexin), lutamide, and there are newer ones, stronger versions, called enzalutamide (Xtandi), apalutamide (Erleada), and darolutamide (Nubeqa). For most patients who present with advanced prostate cancer, I think this is much easier, ADT along with either abiraterone or one of the newer, stronger anti-androgens, is the standard of care for most advanced prostate cancer patients with metastatic disease.  

And then, sometimes for patients with higher volume or more aggressive cancers even in the group with metastatic disease, we even add on another treatment, usually chemotherapy, something called docetaxel for what we call triple therapy. And then, maybe that’s a segue to chemotherapy, so docetaxel chemotherapy is a common chemotherapy used for prostate cancer, certainly advanced prostate cancers. Cabazitaxel (Jevtana) is also a common chemotherapy in this situation. These two are related drugs in a family of drugs called taxane chemotherapies and basically they kind of block the trafficking of important components within cancer cells and cause the cancer cell death.  

Docetaxel (Taxotere) is the more commonly used one. It’s typically used earlier, before cabazitaxel. And like I said earlier, for certain patients with what we call high volume metastatic prostate cancer, it’s often used in combination with hormonal therapies early on, what we call upfront therapy for six cycles. If a patient doesn’t receive docetaxel up front, docetaxel is commonly used after progression, after the cancer has progressed on ADT and one of the oral hormone medications.  

Cabazitaxel is more commonly used after a patient has previously received or progressed on docetaxel. Both drugs have been evaluated in randomized Phase III clinical trials and have shown to provide efficacy for patients with advanced prostate cancers.  

In addition to these taxane chemotherapies, platinum chemotherapy, such as carboplatin or cisplatin, are sometimes used for advanced prostate cancers as well, especially for certain neuroendocrine or small cell prostate cancers. These are rarer cancers, but they tend to respond better to platinum-based chemotherapies.   

Or for certain what we call aggressive variant prostate cancers, these platinum-based chemotherapies are also used in combination with either one of the taxanes or with another chemotherapy drug called etoposide. In terms of other treatment modalities, I think recently what we call radiotherapeutics or radioligand therapies have gotten a lot of press with the approval of a new medication called lutetium PSMA or 177 lutetium PSMA 617 (Pluvicto). 

The brand name for that in the U.S. is Pluvicto and what this is is a drug that’s a small molecule that binds to PSMA, which is a protein highly expressed in close to 90% of prostate cancer, advanced prostate cancers. And the small molecule will home to the cancer and it’s linked to radioactive lutetium and the lutetium will decay in that area and lead to cancer cell death.  

So, Pluvicto or lutetium was FDA approved in spring of 2022 based on randomized Phase III trials that show significant efficacy for patients with metastatic castration-resistant prostate cancer who have previously received a second-generation androgen receptor pathway inhibitor, such as abiraterone and enzalutamide, as well as a taxane chemotherapy, like docetaxel or cabazitaxel.  

The medication is given intravenously, once every six weeks, for up to six doses, and there are ongoing clinical trials, actually, that are trying to evaluate this medication in earlier settings where patients haven’t gotten prior chemotherapy before. There was a press release from about half a year ago stating that they’re seeing some early encouraging signs of efficacy with this drug, even in patients who had never received chemotherapy before, so it may be a medication that is going to be used more and more so in more patients even earlier in their course of disease. they’ve shown pretty solid activity for those kinds of cancers.

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.

David: 

Hello, my name’s David. I am 58 years-old.I was diagnosed in 2016 with prostate cancer, I had no actual signs or symptoms of prostate cancer, it was only found due to Army doctors, I had something wrong with me, which had nothing to do with the cancer. They did a PSA check, and my PSA came back at 1050, where it should be around 0. From that I then got sent to a local hospital where I had tests, I had biopsies to open my prostate, which found out I had stage IV prostate cancer. 

From there I got asked would I like to go to the Christie County Hospital in Manchester, UK. From there, they offered me the trial called the STAMPEDE trial. This trial was used in different procedures, which is already around, we use them together to try and extend people with prostate’s life. I got to turn the arm where it was also attached with chemotherapy, followed by 20 sessions of radiotherapy. This happened over three, four months, which after that brought my PSA down, but only to round 20 odd. From this after a couple of months, my PSA started to rise fairly quickly. I then got put onto the drug called bicalutamide (Casodex). This lasted a couple of months, because my cancer is so aggressive, it started to grow. I then got put onto another chemotherapy, cabazitaxel (Jevtana). After my first session of the cabazitaxel, I then got a CT scan and from this we found out the growths were still growing. 

So after this, I then got put on a drug called abiraterone with [inaudible] which is a stand-only. I was on this for 22 months, which was very good, it brought my PSA down to eight, which is as low as it’s ever been. Like I say, it lasted 22 months, but then the cancer started to come back quite a bit, so my oncologist actually said there’s no actual normal treatment left for me, and asked would I like to go on to trials, clinical, a first stage clinical trial, right away I said yes. My first clinical trial was a Carrick called Carrick, this lasted six months, but again, the cancer started to grow again, so I came off of this. I then have four weeks, no trials at all. It’s what called a clean-out where you can’t have any drugs at all in between trials. I then went on to what was called task 368-1, this lasted longer which lasted seven months. That again, the cancer starts to grow again. So, then I got on this one called CellCentric For the the CellCentric trail, they put you back on to abiraterone, which normally you don’t, wouldn’t take past one to two months… for me, it’s carried on working again. It’s now on seven months of working until it stops working, I can’t go on the new drug called CellCentric. 

For me, this is cool because it’s still working, the old drug, and it’s a very…let’s say there’s not a lot of side effects except for what steroids [inaudible]. So at the moment, we’re just seeing how it goes. I have scans every eight weeks, a CT scan and a full body scan from each time they come back, they then decide what’s happening next…and that is my journey up to now, which is five-and-a-half years later. 

With the clinical trials, I feel really good at the moment, because as I said, the trial [inaudible] and abiraterone (Zytiga) is not a drug that causes a lot of side effects. Through other trials have been, they are very intense, and that’s what they always warn people, which are overnight stays when you first take the drugs, so they are very tiring, you have to have blood done overnight all the way through the night, you get BCGs to make sure your body is not reacting to the drugs, and then the side effects of the drugs after.  So, they are very intense, but also, I am still here, I did not expect to be here. October, this year October I got told I would not be here three years ago, so it shows what clinical trials can actually do for you.  I’m still here, I still live a very good life. We go walking, the wife and I quite often, and we did three, four-mile last night, and we just enjoy our lives. 

People don’t realize…a lot of men don’t talk about it the physical side and the sexual side of prostate cancer, the treatment, because your libido to go, and it just causes a [inaudible] of your testosterone. You don’t feel like…and it’s a closeness that you lose… Amanda’s been unbelievable, she’s been there for me all the way through. She’s my rock, she’s the one went down down, she pushes me, but then she has days where she’s down. And this is where people need to realize the partners will improve the encounters much as the patient. And this is some of them we talked about…we’re very open about people where we talk about it. We have our days, the last couple of days I’ve been down. But she’s there to try and help me get back, and I try and do it for her when she is…and the family is the same, having the family support, when I’ve been to appointments, I get phone calls, quite a few, I get messages how are things going. And it’s just nice knowing that people do care, we have friends who keep in touch all the time, make sure everything’s okay, and you need that support of your family and friends. 

It’s very important for them to be there with you. 

The clinical trial to me is drugs that normally are not being used on humans before. They’ve only been tested in the laboratories. So, the first stage is a dosage stage where they check in and see what a person can actually take…so different people have different amounts of the dose.  And then from there they go to the expansion stage, and that is when they bring more people, and they know what dose to give people. Well, it’s to find new drugs, which can help other people in the future, as well as myself…I always say to myself, “This could help someone in the future, live for longer, stay longer with their family, be there longer.” It’s helping me other months, as I say, but it’s also to help other people in the future, something that’s not been used with people before.  

What I would say to other people who are thinking of going on clinical trials and the families is go for it. They are done so carefully, you’re checked all the time, your bloods are checked, your health is checked, your [inaudible]. It’s something that you can stay longer with your family. There could be cures in the future with this as well, no one actually knows, and it’s something people should not be scared of doing. Like I said, I’m on my third trial, and I will keep on going, I know there are more trials for me after this. And I will keep on going.

Katherine:

I’d like to start by asking about developments in prostate cancer research and treatment. Experts recently gathered at the annual American Society of Clinical Oncology meeting, also known as ASCO, to share their research.

So, what were the highlights from that meeting that you feel patients should know about?

Dr. Hussain:

I think probably perhaps I can focus on two major – what I would consider major highlights, and those were the results from two randomized Phase III clinical trials.

One of the trials is called the VISION trial. And the VISION trial was a Phase III randomized trial evaluating lutetium-PSMA-617 treatment in patients with metastatic castration-resistant prostate cancer. And the delightful thing about this study is that that study was positive. The PSMA story has been really going on for a few years now. And there’s the PSMA for purposes of scans, imaging, to assess the cancer. And the FDA just approved a PSMA PET imaging this year.

I think it was in May when it was approved. And that would help better define if the cancer is spread or not, and it help with the decision regarding treatment. But the second part is treatment purposes, so identifying the cancer location and trying to attack it with a specific sort of targeted attack to the tumor is really important.

And so, the FDA is currently looking at this particular agent. And I am hopeful that we will hear soon from the FDA, hopefully before the end of the year, and maybe – who knows? – maybe by summer, middle summer or end of summer. Because I do think that would be a major benchmark in there. And so, that’s one thing.

The other clinical trial that I thought was interesting from a data perspective – and for disclosure, I am one of the investigators on this study. And this was an intergroup Southwest Oncology, or SWOG, sponsored clinical trial. So, it’s a federal study that Dr. Aggarwal presented. And this was a study that was aiming at maximizing, again, the anti-tumor therapy with the use of a drug which I call is the younger brother of abiraterone.

So, abiraterone is a drug that is FDA-approved and has been around for several years right now for both castration-resistant prostate cancer and certainly hormone-sensitive metastatic disease. And so, TAK 700 (Orteronel) is a younger brother, I call it, of abiraterone (Zytiga). And one of the potential advantageous when this trial was designed was the fact that you don’t need to use prednisone. And the trial was completed. It was a national clinical trial. And what was interesting is that there is certainly what appears to be a potential benefit, but not in terms of the conclusive based on the way the study was designed.

Having said that, what I thought was remarkable is that patients who basically were only on the control arm was LHRH therapy, so this could’ve been like leuprorelin (Lupron), goserelin (Zoladex), or something like that plus bicalutamide, which is what we call combined androgen deprivation. And that was sort of like the strongest control arm we could do at the time when the trial was designed.

Remarkably, the patients who were on that arm had a median survival of basically 70 months. That’s the median. That’s the bell-shaped curve with the number in the middle. Seventy months is probably the longest ever in any other randomized trials in this disease space, in the hormone-sensitive space. So, that tells us is that men are living longer with prostate cancer, even though it’s metastatic disease; and, yes, it’s not necessarily curable, but men are living longer. And it’s a function of all of the better treatments that are supportive care and everything that was going on.

And so, the control arm, as I mentioned, was the 70.2 months. The actual experimental arm was about 81.1 months. And again, I don’t know where things will go from this. Obviously, I’m not the sponsor not the FDA. But the point here is that men are living longer, and so wellness and health become even more so important than we ever did. And as I tell my patients, every day you’ll live longer. The odds of living longer is there because of better treatments coming on.

So, to me – not to take too much time from the interview – to me, these were the two highlights: new, approved – I’m sorry, new treatment that I’m hoping will be FDA-approved and, obviously, the fact that men are living longer.

Katherine:

How can patients keep up to date on the research that’s going on?

Dr. Hussain:

I’m a bit biased, obviously. I’m a member of ASCO.

And what I would recommend to my patients is to look at the cancer.net website. The cancer.net is a website that is an ASCO-generated website specifically for patients and families to review. It is vetted. The committees are not run just by physicians, oncologists, a multidisciplinary team, but also patient representative. So, the lingo and the presentation are lay-friendly, I call it, there.

The other part I would say, the NCI website, and the American Cancer Society, the American Urological Association. I would say there’s a lot of stuff on the media. The difficulty is vetting what is sort of fake, what is not so accurate, or bias versus there. I also think that the NCCN has also some resources for patients.

And one thing I always tell patients: explore, look, but make sure that you talk to your doctor about the meanings of everything because sometimes it can be not – it could be misleading, I should say, or maybe not very clear on what the implications are.
