Katherine Banwell:

As we know, researchers are still discovering new markers. Could you tell us about the latest news and research in biomarker testing for non-small cell lung cancer? 

Dr. Grace Dy:

Oh, there is a lot going on. You know, sky’s the limit. But just an example: we have liquid biopsies that are in clinical use right now, typically in the stage IV setting.  

But beyond that, we’re also having what we call minimal residual disease testing in what we call adjuvant situations. For example, patients who had surgery, there’s a big proportion of patients who still relapse.  

So, finding out – and our scans are imperfect. They will not be able to detect micro metastatic clones or even a small cluster.  

If you have a million cancer cells clustered somewhere, it will not show on the scan. 

Katherine Banwell:

Each and every one of them. 

Dr. Grace Dy:

Right. So, is there a better way? And so, that’s the question: can we detect it in the blood? So, these are assays that are being developed. Looking at different angles, not necessarily mutations, but maybe what we call epigenetic, meaning changes on top of the DNA that makes the DNA molecule be different in terms of whether some areas of the gene will be expressed or not. 

And so, looking at these patterns because they’re different in cancers versus non-cancers. So, whether you can see it in the blood. So, it’s a ripe area.  

There’s a lot of – so, there’s some overlap with early cancer detection and MRD, or minimal residual disease testing. 

So, I think there’s an intense interest in developing these. But none are fully validated yet. There are trials that are going on, the studies that are ongoing to prove the utility and validity of these tests. So, we’re very excited. And obviously, AI everywhere. You have ChatGPT, right? So, you have AI being incorporated in diagnostics as well, in radiology, in pathology, to see: hey, maybe can we use AI technology to even maybe one day give us a mutation profile, right?   

Katherine Banwell:

Yeah. 

Dr. Grace Dy:

And that would be huge, right? But we’re not there yet.

What is the role of antibody drug conjugates in lung cancer care? 

Dr. Grace Dy:

So, the antibody drug conjugates are an exciting new class of therapy. In fact, it’s been developed for decades, but we had the first antibody drug conjugate that was just approved less than a year ago in lung cancer. And that’s the drug called trastuzumab deruxtecan (Enhertu). It seems like we’re always steps behind our breast cancer colleagues. 

You know, trastuzumab deruxtecan was first developed in breast cancer patients. But hey, we also find we can have some subset of patients who will derive benefit from that. But that’s just one example. There’s plenty of antibody drug conjugates that are being developed. 

So, what are antibody drug conjugates? So, as the name implies, it’s an antibody that is attached to a drug that is actually typically chemotherapy, but you can use any other drug. Generally, it’s a chemotherapy. So, you can think of it as a targeted way of delivering chemotherapy because the antibody is very specific to a certain protein. And generally, what we try to do is look for proteins that are more expressed in cancers than in normal tissues. And you try to target that and improve the therapeutic index by using a more potent chemotherapy and potentially increase efficacy that way.

Katherine Banwell:

How does testing impact treatment and care? 

Dr. Grace Dy:

So, back in like maybe more than two decades ago, I was still in school. The treatment paradigm is sort of like a one size fits all. You come in with a lung cancer diagnosis. Everybody gets treated the same.  

But with advancements in technology and understanding of actually what we call lung cancer is really genetically very different from one patient to another. We are actually not even still able to tease out all the particular details, but there are some improvements that have been made along the way. And so, defining, for example, mutations in cancers, there are what we call driver mutations that have a matched targeted therapy.  

In certain patients, actually the target therapy works so much better than chemotherapy, for example. And that’s why we have it in guidelines based on the results of clinical trials showing that in the appropriate setting, if you have a mutation that we discovered through molecular testing, and then you use the matched target therapy, survival is so much better compared to, for example, chemotherapy.  

Same with immunotherapy. If we use a biomarker to test out which patients may actually respond well to immunotherapy alone – so, that’s a major treatment paradigm change within the less than 10 years wherein we define there’s a group of patients where that’s all they need. Non-chemo, just immunotherapy, and they will do well. 

Katherine Banwell:

What are some of the mutations that are being targeted? 

Dr. Grace Dy:

Right. So, it seems like every year, it’s growing. So, it started off with the poster child in lung cancer story of EGFR. So, we have EGFR mutations. Even EGFR mutations, they’re a subtype of mutations for – there are certain drugs that work better for certain mutations.  

So, we have the classical EGFR mutations, the atypical EGFR mutations. But EGFR mutations as a group are probably the most characterized given the longevity of the research that has been done. But there’s a lot more. 

So, for example, ALK, KRAS, BRAF, HER2, NTFK, NRG, RET, MET. Even those mutations, they’re all these new ones. It’s between the subtype of mutations. For example, we talked about EGFR. Same thing with MET. You have MET exon 14 skip mutations. But in the absence of MET skip mutations, there are also what we call MET gene amplification, MET protein over-expression that have matching therapies that may actually work better. 

But we’re still kind of scratching the surface. There’s a whole lot more being characterized and developed. Case in point, just a little over a year ago, there’s an LTK Fusion that was described. Very rare. But there’s a target therapy for it. So, unless you test it, you won’t find a matching targeted therapy.

Dr. Grace Dy:

My name is Grace Dy. I’m a thoracic medical oncologist at Roswell Park Comprehensive Cancer Center here in Buffalo, New York. 

Katherine Banwell:

Thank you for being with us today.  

Dr. Grace Dy:

Thank you for having me. 

Katherine Banwell:

What is biomarker testing, and is this the same as molecular testing for non-small cell lung cancer? 

Dr. Grace Dy:

That’s a very good question. So, let’s first maybe define what biomarker means. So, biomarker is an all-encompassing term relating to a measurement of a biological parameter. That’s what it means.  

So, you can actually have biomarker related to imaging. So, it’s not specific to a particular test. But what it’s trying to do is to guide doctors in making decisions. So, you can have, for example, a PET scan as a biomarker to indicate the effectiveness of therapy. 

So, it’s not specific to a test. So, it’s a broader scope. But in cancer, generally, it’s used interchangeably with molecular testing. And molecular testing is a more focused test on the genetics of the cancer.  

In some aspects, sometimes it also refers to testing for proteins, characteristics of different proteins in the cancer. Again, to help doctors generally define what might be a better treatment option that is personalized to the patient’s cancer. 

In some instances, the biomarker can also be what we call prognostic, meaning independent of what we do with the treatment, it may define to us how well a patient will survive or have their outcomes, whether they have treatment or not. 

So, those are maybe the nuances between a predictive versus a prognostic biomarker. But for all intents and purposes, the most common test that we use for lung cancer patients are what we call predictive biomarker testing. Molecular testing is one of the ones that we often commonly request to help us define treatment modalities, especially in non-small cell lung cancer.

Katherine Banwell:

What safety measures are in place to safeguard patients?  

Dr. Grace Dy:

So, there’s a lot of safety measures involved. Not just within the protocol but there are also governing committees. IRB, Scientific Review committees, that look over – and these committees typically also, actually, involve some patient advocates that will be reviewing the protocols to make sure it’s not just a scientific aspect that is looked into but also patient perspectives that are looked into when we review these protocols.  

So, from the medical perspective, protocols are generally written with guidelines to help treating doctors how to manage side effects. For example, because of the intense preparation – what we call pre-clinical, meaning the preparation done in animal models, in learning from other settings, for example; from other drugs, for example. If it’s not the first in class, you have a sense of what potential side-effects might be expected and so you prepare accordingly.

Questions to Ask Before Participating in a Lung Cancer Clinical Trial

Where Do Clinical Trials Fit Into a Lung Cancer Treatment Plan?


Transcript:

Katherine Banwell:

What are some common concerns you hear from patients when discussing lung cancer clinical trial options?  

Dr. Grace Dy:

When I discuss clinical trials, the first question generally patients ask is: well, how effective is the drug, right? And the second question will be: well, what are the side effects? And those are very valid questions, but we may not always have an answer to it, especially if they’re in early phase. I do a lot of early phase clinical trials, meaning sometimes we don’t even know the proper dose of the drug to use, for example.  

And the intent of the trial, for example, in Phase I, generally, is to find out what is a proper dose to use that is safe and effective before we can do a test in Phase II setting using the recommended dose to test it out more rigorously how well it works. And if it passes Phase II, then we go to Phase III, which then generally is comparing it with the standard to see whether it will be better or at least equivalent or non-inferior. 

And you may ask, “Well, why even do a non-inferior?” Because, well, some drugs, it may not prolong your life more than current therapies, but if it has better side effect profile, right? So, there are actually drugs that are approved through non-inferiority trials. But those are the common concerns, and I think another common concern that I hear when I talk about trials, patients are concerned about receiving placebo. 

Katherine Banwell:

And what do you tell patients? 

Dr. Grace Dy:

Well, it depends on the design of the trial and the question that is being answered. So, in fact, for example, some situations in the standard of care is not to do anything. The best way to remove bias is to administer a placebo because the standard care would be not to do anything. And those, generally, are Phase III, you know. An early phase, Phase I, Phase II generally there are no placebo involved. I mean, there are some randomized Phase II trials that there are placebo involved and I explain to the patient why placebo may be involved and it’s usually on top of a standard of care. So, there could be a standard of care therapy but you add something else. So, you want to compare it with a new drug plus the standard of care. So, you might add placebo so that the doctors will not be bias when they measured their scans, for example. They say oh, this patient is getting this experimental drug. So, they’re excited. They might oh, you know, make it look better than what it actually is.  

Katherine Banwell:

Now, as a researcher yourself, do you always know that a placebo is part of the clinical trial testing?  

Dr. Grace Dy:

Yes, it will be in the design. So, it will say there is a placebo control. So, the title, or the design, generally will tell you this is a randomized, double-blind placebo control. Usually if there is a blinded there might be some placebo involved because then you don’t know what people are getting.

Key Questions Patients Should Ask Before Participating in a Breast Cancer Clinical Trial


Transcript:

Katherine: 

Well, what questions should patients ask their team before they even begin a clinical trial? 

Dr. Ramaswamy:

I think most important thing, and in – and usually, a doctor would – should really explain this to you, particularly if it’s a little bit of a complex study with a paper and pen. They need to tell you if this is two arms, that you may be randomized into this arm versus this arm. So, what you need to understand is what are the drugs and what are the differences between these two arms? Whether you go into this arm or this arm, are you going to be compromised with your outcomes? And that is important to understand. And now certain arms may have a little bit more blood draws or scans. And so it’s important to understand what it means, what commitment of your time and other things that goes on with different treatments.   

So, again, these are important for you to understand. Also, it’s important for you to know what is that experimental drug? What is that new drug? Right? And what data do they have from the past about this drug? Has it been tried in humans before or is this the first in the human study? And what does a target, why is it used in my cancer? How do you think it’s going to work? And what are the side effects that comes with this experimental drug? Mm-hmm. I think for you, the most important thing is to understand what is your commitment because the commitment during clinical trials can increase a little bit. You may have to come in, stay a bit longer to kind of check the drug levels in your body, in your blood, or do more testings, blood draws, and things like that.  

Are you willing to do that? That’s something for you to answer. Don’t feel that you need to do this for some reason other than it fits your life and it fits your philosophy, okay? But also don’t push it away thinking that just because you don’t know enough and you’ve heard things from outside, it’s important for you to hear it from your providers and understand it clearly and then make a decision that’s right for you.

Transcript:

Katherine: 

Let’s talk about where clinical trials fit into a breast cancer treatment plan. When should someone with breast cancer consider a trial? 

Dr. Ramaswamy:

And the most important thing again here to understand is clinic – you should consider a clinical trial at all aspects, all parts of your journey through this whole diagnosis and whatever the outcomes that you are going to have. We all have a lot of misconstrued ideas about clinical trials. And one of the thing is we think clinical trials are only when standard of care is not needed like that is that – we don’t have other treatments. That you are coming to a point that you don’t have other treatments and now you should go to clinical trials. That is not true, right? Because the fact that you can have these treatments in your curative setting came because many of the patients before you were willing to go on the trial that compared standard of care, which may not have had that new drug with a competitor to the new drug with the standard of care.  

So, nobody gives – the important thing to understand is no one is going to give you a placebo alone for cancer treatment. Think about that. I mean, there’s no way a doctor whose oath is to cure you to help you is going to just give you placebo. So, it is important for you throughout your process to actually ask. In fact, we used to wear a badge to say ask your doctor about clinical trials. So, ask your doctor about it, even if they miss it. Just ask, is there a clinical trial that I could fit in? They’re supposed to look for it, but you don’t need to leave it at that.  

Ask at all aspects of your journey for a clinical trial option. If you are not suited for the trial, no provider is going to put you on that trial because everybody   has  the same goal that you need to get better. Your  chances of getting better is high.

Katherine: 

We often hear the term precision oncology. What exactly does that mean? 

Dr. Ramaswamy:

So, precision oncology is again, one of the ways that we are getting better, right? So, what we are trying to understand is that originally, we just understood cancer as just where all it is and how spread it is. Again, an anatomical. Now we are getting more and more into the biology. So, in the biology we were focusing more on the RNA. There are two things, the RNA and DNA. DNA is your code, and RNA is the one that comes from the DNA kind of the message that goes, makes the protein, which changes everything in your body. So, we were focusing on the RNA, which are the biomarkers, right? Because we – you that that’s what drives the cancer. Now we are focusing more on the DNA. What is changing within the core, that blueprint in the tumors that is causing resistance that is making cancer cells worse?  

Could we target those? And so that is what is precision oncology. They’re trying to understand the genetic core change within your tumor and maybe able to target that. You could have breast cancer, you could have a completely different cancer like lung cancer. But if you have the same genomic change or gene change within the tumor, could we just target that cells and be able to get a really good response? And those are the kind of ways we are going towards. And I can tell you it is as you hear this concept, it sounds like so bizarre. I’ll tell you, I felt the same too when it all started, even as a scientist and an oncologist. But it is truly becoming a reality. And in certainly in more some cancers more than the others, but it’s slowly becoming a reality for all cancers. So definitely, again, a positive and a tailored therapy to the patient. And so that’s what we want.

How do biomarker test results impact prognosis? 

Dr. Ramaswamy:

All of them do because it’s important to understand that that’s why this – these biomarkers carry a lot of weight. Biomarkers are good, are important, but when the most important biomarkers are that are going to impact outcomes. And then even more important is whether they’re going to predict the efficacy of a treatment, the outcomes used by the success of a treatment, right?  

So, in that way, if your tumor is estrogen and progesterone receptor- positive, then you generally tend to do a little bit better. And they are slightly better tumors for sure, and you know that the anti-estrogens would work. So, these – there’s two ways. They are prognostic and predictive. Now, the whole two positive tumors previously used to have a worse prognosis, but we have such wonderful anti HER2 therapies now that we can use. Now we know that if you use those therapies, the outcomes are better.   

So, it’s predictive again, that predictive of the treatment and prognostic. Now the triple negatives are usually a little bit more difficult to treat because as you can understand, they don’t have any of these targets for us to use targeted therapy at this point. There is definitely some improved outcomes using immunotherapy, but you know that we don’t have those proteins. So, slightly worse outcomes for sure, triple negative among all of these subtypes. And also there is no biomarkers.  

We do use immunotherapy, which is helping certain percentage of those patients, but we still need to understand why it’s not helping other people. So, yeah.

Transcript:

Katherine: 

Patients are often confused about the difference between hereditary genetic testing and biomarker testing. Would you explain the difference? 

Dr. Ramaswamy:

Absolutely. So, the hereditary genetic testing is what are the genes that you got from your parents? It could be mother or father. And we all think that because it’s breast cancer should be just from mother. It doesn’t matter. It can be from mom or dad. And that influences your breast cancer risk. So, if you have some mutations or some changes in certain genes that can increase your risk of breast cancer. And the well-known ones are the BRCA1, BRCA2, but we also now know a few more like the PALB, ATM and CHEK2 and other things.  

So, now when you do have a family history, or sometimes even based on your age and your oral history, we do test for this hereditary risk factors that you might have and that may influence your surgery and some type of treatments that we give as well.  

Now as far as biomarkers, biomarkers are more proteins that we check in your tumors. The breast cancer that you already have, and that we may do the biopsies. We look for these tumor proteins that influences the growth of your cancer cells. So, we can target these biomarkers and decrease the growth of your cancer cells.
