Katherine:

Dr. Sen, you are a leading researcher in the field. What is the latest research news that you can share with us about small cell lung cancer?

Dr. Sen:

There’s a lot of great research going on in my lab and labs all across the world. I think for the first time in a very long time, we are really trying to dissect the biology of small cell.   

It has been a research in making for many years. I think we have now really come to a point where we are really trying to understand the disease. I’ll go into a little more about the questions you are trying to answer. So, one of the main questions or one  of the main things that kind of is a hurdle to getting durable treatment options is that the frontline chemotherapy and immunotherapy doesn’t work as well as they should even for the approved regimens, which is the chemotherapy and the immunotherapy.  

The patients often do not have durable benefits. Even if patients have durable benefits, it’s only in a very minority of patient population which means in only about 10 to 15 percent of the total patient population actually do have any benefit from the frontline treatment. So, the main question that we are trying to answer is that why do these patients not respond to immunotherapy and chemotherapy in the frontline.  

What are the mechanisms of resistance to chemotherapy and immunotherapy? Primary resistance, what I mean by primary resistance is that patients who never respond. The disease comes back even while they’re getting the frontline chemo. So, the primary resistance, the mechanisms. Of course, when they have acquired resistance after the maintenance regimen when they come back, why are these patients having this acquired resistance to chemotherapy and immunotherapy? Because only when we understand resistance mechanisms will we be able to then come to the combination strategies.

That’s the next area of research is that once we understand the mechanism of chemotherapy and immunotherapy resistance is then coming up with effective combination therapy. So, what should we combine with immunotherapy in order to make immunotherapy better? I’ll give you an example from the research that we did. 

So, our lab focus is, as I said, on making immunotherapy better. What we understood is that there are certain epigenetic modifiers like LSD1.  

Repressing these, repressing LSD1, with a small molecule inhibitor actually augments or benefits the response to immunotherapy. So now, we are looking at LSD1 inhibitors in combination with immunotherapy. That’s one area that we are focusing on. The second are that we published extensively on is DNA damage response inhibitors which really works in combination with immunotherapy and makes immunotherapy response better.  

Now, we are investigating that in the lab the combination strategies of combining these DNA damage response inhibitors with immunotherapy. So, combination strategies. I think always coming up with novel targets. I will mention there are many novel targets that are right now in the clinical trials actually showing really, really encouraging data.  

I’m talking about DLL3 targeted BiTEs or ADCs we have seen that are showing preliminary data. We have seen a really good really good response in patients. So, finding these targets that are very specific for small cell and that can work in these unique population of patients.  

So, DLL3 targeted agents. There are agents that target B7-H3. So, we are looking at these novel targets and where they could fit in the current therapeutic regimen. Finally, since small cell lung cancer is not a surgical disease, we have to look for other options to find biomarkers. So, liquid biopsy. Liquid biopsy, what I mean by that is understanding the disease not just from tissue but also from blood.  

There’s a lot of research that’s happening in understanding the biology of small cell from blood draws from these patients.  

So, the field of using liquid biopsy or understanding the disease from blood draws is one of the areas that many labs, including ours, are focusing on, and how we can utilize these blood samples to then monitor the disease and also understand the resistance mechanisms to various drugs. I think these are the areas that we are investigating and seems, to me, very important areas that we need to address in order to really manage small cell lung cancer.   

Katherine:

What do these advances mean for small cell lung cancer patients? Are you hopeful?  

Dr. Sen:

Oh, yes. Of course. We’re always hopeful. That’s the goal, right. The goal is to have effective therapies that work and that works for a long time. That also benefits the patients in terms of quality of life which means without very severe adverse effects.   

So, very hopeful. Because I think what was limiting us for all those years for the last 40 to 50 years is that we really did not understand the complexity of small cell lung cancer. It is a very complex disease. It is very different from non-small cell lung cancer which has these mutations that you can target drugs against. So, there are this EGFR mutations and KRAS mutations in non-small cell.  

But small cell, it’s not that. It is not a disease where we have these GATA function mutations that we can devise therapies against. It’s a very different disease. The disease is aggressive. The disease progresses fast, and it also changes its physiology very fast. So, I think for the first time, we really are trying to understand the biology. What that helps is then to come with very informed decisions about therapy.  

So, yeah, I’m very hopeful. Because I think we have now targets that we are actually seeing benefits in patients. I think the more and more we understand resistance mechanisms, we’ll also be able to manage that better.   

Katherine:

That’s very promising news.

Advice for Small Cell Lung Cancer Patients Considering Clinical Trials 

Transcript:

Lisa Hatfield:

And, Dr. Ernani, can you please explain research advancements in immuno-oncology and what this means for extensive-stage small cell lung cancer patients? And how do you envision the treatment landscape evolving over the next five to 10 years? 

Dr. Vinicius Ernani:

Yes. So over the last 30 years, we’ve had multiple Phase II, Phase III trials and, unfortunately, we were not able to move the needle in small cell lung cancer. However, over the last few years with the advancement of immunotherapy and incorporating immunotherapy to the standard carboplatin (Paraplatin) and etoposide (Toposar), we were able to finally make some progress in small cell lung cancer.

So now we know that the standard of care is to give chemotherapy plus immunotherapy, and we have at least three to four randomized Phase III trials showing the benefit of adding immunotherapy to chemotherapy. And I think this is a very exciting time for small cell. We are seeing at least over the last couple of meetings, over the last year, I’ve been seeing at least two promising drugs.

 One is tarlatamab that was the Phase II studies called the DeLLphi trial, was recently presented at ESMO. And there’s also an antibody drug conjugate that has also been very promising in small cell. So we’ll see how these studies are going to play out, especially the antibody drug conjugate, that’s still a Phase I study. So it’s a little bit early, but encouraging response rates. And the tarlatamab, which is a BiTE, and what I mean by BiTE, is a bi T-cell specific engager. I think it’s probably going to be soon approved by the FDA, and I think it’s going to change the standard of care in small cell again.

 Lisa Hatfield:

Dr. Ernani, with regard to the DeLLphi trial, can you explain who that is for and more specifically maybe what the hope is for patients and their families?

Dr. Vinicius Ernani:

Yeah. So the DeLLphi trial was a Phase II study. So usually we have three types of study, right? First, we have the Phase I study. Phase I studies are usually looking at how safe is a drug, but we are not looking too much of how active the drug is. We’re just making sure that the drug is safe to give to the patients. A Phase II study is a little bit bigger than a Phase I, and we are looking still at safety, if the treatment is safe, but we are trying to look a little bit more careful and how active this drug is.

In Phase III, those are usually big studies that randomizes 200, 300, 400 patients to the standard of care compared to the new drug. And that’s usually where we get the FDA approvals. So the DeLLphi-301 trial was a Phase II study that enrolled patients with heavily pretreated small cell lung cancer, extensive stage small cell lung cancer, to receive tarlatamab.

 And they had two doses. It was 10 milligrams and 100 milligrams. And it seems that the 10 milligram cohort, that actually the responses were even better than the 100 milligrams. So we saw the presentation at ESMO, it was actually published in one of the most respected…probably the most respected journal of medicine, the New England Journal of Medicine, and there was a response rate of 40 percent. So if we could give tarlatamab for patients that fail at least two lines of treatment, the chances of them responding to tarlatamab is about 40 percent.

And more importantly, I think that the duration of response was greater than six months. So what I mean by that, more than 50 percent of the patients that received this drug, they controlled the cancer for at least six months. So I think that’s a very positive about this drug.

Lisa Hatfield:

Great, thank you. And then one follow-up question I have about that. So if a patient were to come to you or go to their local oncologist and say, I’m really interested, I heard about this DeLLphi trial or any clinical trial, what is the advice you would give to that patient on how to access that clinical trial?

Dr. Vinicius Ernani:

Well, unfortunately, we don’t have at our institution, what I usually help my patients,  I go to clinicaltrials.gov and I type their cancer, and I go over with them on where the trials are open, and we try to find a facility or a cancer center that is close to where they live. So that’s what I usually do when I’m trying to find a clinical trial that I don’t have available in my site.

My activation tip for this question is, again, I think stay tuned. This tarlatamab might become, down the road, a new standard of care for our patients.

Transcript:

My name is Terrence, and I’m living with extensive-stage small cell lung cancer (SCLC). This diagnosis came as a shock, but I decided to persevere and fight. Cancer care can feel like a marathon, and certainly not a sprint – particularly for patients like me. As a small cell lung cancer survivor, I want to share my perspective and lessons learned from my cancer journey about staying ACTIVATED in your care.

My symptoms started with a cough that wouldn’t go away. As a military veteran, I assumed the cough was something I picked up years earlier. And even though I had been a smoker, my doctor didn’t order any scans as a pre-emptive screening measure, nor did I know what questions to ask. It wasn’t until I found a lump under my arm that further testing was done. It was at that time that I also put the other pieces of the puzzle together, which included symptoms of higher than normal blood pressure and knee pain.

I received chemotherapy and radiation, and also quickly learned that despite the challenges of treating my cancer, maintaining a positive attitude was the most critical part of my regimen. I was fortunate to have a medical team that listened to me and didn’t dismiss my concerns. Just as in battle, I understood early on that a solid partnership with my healthcare team would be crucial to my outcome.

Under the care of my healthcare team, I continue to receive scans of my lungs and brain every three months and feel grateful to be doing well. My care team and I also actively look for clinical trials that may be right for me. I urge other small cell lung cancer patients to ask your care team questions to learn about treatment options and what to expect during and after treatment – you matter. 

For the past decade, there have been a lot of research advancements about non-small lung cancer (NSCLC) treatment, but our small cell lung community is feeling left out of conversations about investments to improve lung cancer diagnosis and treatment. The SCLC patient community also deserves improvements in care and treatment. Fortunately, things are changing. Progress in personalized medicine has allowed scientists to develop targeted therapies tailored to a patient’s body using their genes to prevent, diagnose, or treat an underlying disease. Clinical trials are one opportunity to be on the ground floor of these developments where you may be able to get tomorrow’s medicine today. I hope sharing my perspective will make a difference for others. 

While the battle ahead has uncertainties, stay [ACT]IVATED with these tips:

  • Don’t allow stigmas to keep you from getting the best care, now is the time to get the right care no matter how you got the cancer.
  • Ask your care team questions to learn about small cell lung cancer treatment options and what to expect during and after treatment.
  • Ask if a clinical trial may be a potential treatment option for you.
  • Stay abreast of small cell lung cancer treatment options and research advancements.

Whether it’s combat in war or fighting cancer, no matter who you are, take it from me, attitude is everything. Stay [ACT]IVATED by being informed, empowered, and engaged in your small cell lung cancer care.
