+ 00:26:42 - Clinical Trial Challenges from the Patient Perspective (Exclusion Criteria, Diversity, Onerous Trial Design)
Lisa Laudico:
We know that all aspects of the clinical trial process are complicated from the initial inquiry, the funding needed the requirements for how they're designed the recruitment, the execution of the trials and various cancer centers and how patients actually engage with it. We've established that it is a difficult process. So let's take a moment to introduce the additional cast of experts we spoke to about all of these challenges.
To find out more about what think tanks and researchers think about how to make clinical trials more effective in the quest to cure all cancers, we spoke with Kristin Schneemann, the director of FasterCures, which is part of the Milken Institute. In this role, Kristin runs the train program, which stands for the research acceleration and innovation network.
We also spoke with bioethicist, Jill Manning, assistant director of the mass general Brigham institutional review board.
We spoke with Kristin Schneemann first asking her about inclusion and exclusion . Criteria for trials.
Kristin Schneeman:
I know this is an issue that you're very interested in yourself which is, there can be fairly rigid criteria about who's included and who's excluded. And then finally , once clinical trials are conducted the results of those trials, don't always hold true in real world conditions. And in part that goes to the inclusion, exclusion problem that we've tried to create such perfect experimental conditions in a clinical trial, around a product that, that it's not reflective in very many ways of what happens to the real people in the real world who will ultimately take that product.
And the, real world conditions that they're taking them in. There's just so many ways in which clinical trials are not serving the needs and interests of patients. We shouldn't be surprised that they don't always or very often even recruit very well. There many trials that never even get off the ground because they don't recruit adequate numbers of patients. So that's incredible loss potential, right there. Trials that never even managed to happen because of lack of recruitment or lack of retention of patients in trials.
Lisa Laudico:
And here's Jill with her thoughts.
Jill Manning:
I personally am not involved necessarily on the design of trials. We have the saying like you design we opine type deal. However, to get back to eligibility criteria, I think it's really important for people to know about these kinds of considerations. It is standard practice to have strict and rigid, if you say, inclusion and exclusion criteria for a high quality research protocol. And these criteria are always going to be guided by the scientific objectives of the study. And so when we're talking about exclusion criteria, we're talking about the features of individuals who may meet all of the inclusion criteria.
But they present these additional characteristics that could interfere with the success of the study, or they could lead to additional risk for an unfavorable outcome. And so they're always going to be developed with patient safety and sound research principles in mind. The most important thing is that we're talking about, from human protection side of things, which is where I work is always going to be the safety and the protection of those subjects. But we also need to keep in mind that having high quality research results and yielding that generalizable information is critical.
And when we don't have, standard and rigid or so exclusion criteria, this could lead the way for really unfortunate things to happen in data analysis, like selection bias, confounding, other random errors. And then that really skews the results and what our end goal here is to be able to have an intervention. And in this case, perhaps the study drug in which we can really confidently say that the desired outcome is truly associated with that intervention. And while I absolutely think that these screening requirements can feel daunting, overwhelming, and very upsetting and disappointing for many.
We need to honor that and keep talking about that, but it is helpful to keep in mind that they're in place for a good reason, and they're not designed to discourage participation. It all comes down to the science and you need to have that direct association with the study intervention, with the outcome. And when you have other medications involved there, it's very hard to draw a clear line to that outcome. And it's very frustrating.
Lisa Laudico:
Here's Dr. Fischbach confirming that in spite of all of this clinical trials should always be considered at every step for MBC patients.
Dr. Neil Fischbach:
I think that oncologists and clinical trial designers are trying to get better at basic entry criteria, more on a person's fitness and performance status rather than how many prior treatments they may have had, but yes, you still will find trials with ceilings for prior therapy or there's also a situation where you may elect the standard of care therapy. And there's a very attractive clinical trial open two months later, that's the standard of care therapy you are receiving, plus a very attractive novel agent. These are the kinds of things we weigh. And that's why I think it is always appropriate at any juncture and chair to be asking your doc is a clinical trial appropriate for me? What do you think? What's the standard of care available? What are we likely to achieve in that?
And sometimes that brings up uncomfortable discussions about how long do we anticipate that this next therapy you're recommending will last on average. And I know it's important to be hopeful but also very important to be realistic about these kinds of things getting tough, but really critical discussion.
Lisa Laudico:
And I think that speaks to the relationship between patient and oncologist and where that particular patient is in terms of understanding the trajectory of their own disease and how much information or decision-making they want in terms of that next treatment choice. And so every patient takes it a little bit differently, but I think it's that relationship between oncologist and patient, but also the understanding that there are these landmines that can happen, depending on how the clinical trial is designed.
Dr. Neil Fischbach:
Cancer is stressful enough, right? And so I think sometimes we overthink and I think when people are thinking about the clinical trial options and thinking about lines of therapy, am I going to make myself ineligible? I think that we can largely take that out, but that actually is fortunately a rare problem where people are not eligible for clinical trial that we wanted enroll in because the lines of therapy. It's important to think about, but practically is not often. So I just, I think at any decision-making juncture, we can decrease the stress level.
Lisa Laudico:
The example that I just mentioned of too many lines of treatment, therefore not being eligible for a trial that would have normally worked for the patient. It actually just happened to me. But it is illustrative because in speaking with my own oncologist and with the research trial nurses , they have a different approach. They go, we've had this challenge with this particular sponsor and it makes us so mad because they just want treatment naive people and I'm going but that's not the metastatic breast cancer community. We can't be treatment naive because we got to keep going and keep on taking new lines of treatment just to survive. And so they all said, yes, you're right, Lisa, we know it's nuts, but this is the way it is.
Dr. Neil Fischbach:
I also want to instill people who are participating in clinical trials with the thought that they are a exceptionally important altruistic valuable commodity. And it's only it's like being a college athlete, if you're going to be paid once you are due. Drug companies are going to make billions of dollars off drugs that they are developing for the benefit of people living with cancer. But as someone participating in trial, you should be like, you know what? I deserve a lot. I want a parking space. I want a meals. I want transportation, lodging. We at Yale are struggling with this because there's been a lot of concern about conflict of interest that you're paying people to participate in a clinical trial. If you're providing parking or these undue incentives that will influence people to participate and so for a long time, those kinds of services were actually they were rigorously weeded out of clinical trials. And now I think we're getting back to recognizing that no being a part of a clinical trial is incredibly generous and taxing and time consuming endeavor and people should have some benefits associated with that.
Lisa Laudico:
There's less than 5% of the adult population in the U S that are cancer patients are actually engaged in clinical trials. That's incredibly low. And then on top of that, you want to break down the differentiation of that 5% that actually participates in clinical trials. And so it does not at all reflect the metastatic breast cancer community. And so recruitment for clinical trials needs to include not compensation in terms, but taking care of every aspect of that patient's life that will be impacted by the trial. So childcare parking spots is, as you mentioned, a meal, perhaps accommodations, if they have to travel and all of that stuff, so I'm glad you mentioned it because it's an important component that clinical trials we're not just mice. We actually are humans with full lives there needs to be an accounting about that.
Dr. Neil Fischbach:
That is something which has really been increasingly recognized really over the last decade. So at Yale, for instance, like most major academic centers, this is a major emphasis of ours is identifying what are the obstacles to enrollment in a clinical trial, particularly what are the barriers for people of color, people who have less access to care. So one of the missions of Yale university medicine in general over the next decade is providing equal access to care for everybody. And just as you said providing childcare is not payment. That's a big obstacle for people being in a clinical trial. Transportation, the things that as you mentioned, roughly 90%, 94% of our trials are caucasian, generally more affluent where these are not issues. They're really critically important. So recognized hopefully to be better rectified over the near future.
Sarah Mann:
I love that Yale is taking a hard look at enrollment to clinical trials to make sure that unnecessary barriers are removed for people. We won't get a truly reflective pool for each and every clinical trial for the MBC community unless this is a priority at every single cancer center running trials We asked Jill what role IRBs can play in overseeing the issue of racial disparities in clinical trials.
Jill Manning:
It is a really big problem and it is a huge focus right now. I would say certainly the healthcare community, including researchers are waking up to it. But progress is slow. We've had over 300 years of systemic racism and I think that. Understanding and recognizing our history, which is not so distant and truly informs what our current landscape is. Cause there's a lot of valid reasons for hesitancy to take part in research studies. And this distrust is there for reasons and and I think that it's critical that we continue and expand and increase our education, not just to healthcare workers, but to researchers, all the way up from pre-med medical school to ongoing education at each institution and individual institutions have an obligation.
And we are certainly doing this as of looking back at our own histories. And what happened in your local context that may inform where the community is coming from.
I've done different works with building community resources and about how you can become an IRB member. You truly have a voice at the table for the approval of research and community members are an essential component of our review process. Also increased digital access across the board again from COVID we saw that this was a lot easier than people before and when we have increased digital access, we have increased access for all different members of our community. And it is so important that our research participants reflect the actual patient community of which we are serving.
Lisa Laudico:
So the question is Mass General Brigham actually putting some teeth to these new criteria that they've developed so that people are really truly being held accountable and that people in the community can then see, this is how we are holding ourselves accountable, because I think that's the next step in the gaining trust from members of different communities. We're going to do an audit on you, what would it look like?
Jill Manning:
I am seeing that initiative happen in real time in my own department, as far as who we're hiring for leadership opportunities and our cultivation of our membership base, and it is at the forefront of our minds and of our goals. This is the only way that things are going to get better is if we have IRB members who are reading these protocols , on consent processes and procedures, on eligibility criteria or the accessibility of a protocol or whatnot.
We absolutely need those voices at the table. And we are actively working with our division of diversity and inclusion as well as partnering with different individuals and communities to hopefully expand that. And I think then at a system wide level we need to ensure that our actual investigators reflect our patient population as well, that we are ensuring diversity in our hiring of postdocs. I do see real-time efforts at that. And I would hope that folks are thinking about it at the hiring level for individuals early in their career, so that we can keep all of that critical talent at our institutions for the prime years of their career.
Lisa Laudico:
What are the main pitfalls that you find that patients from the patient's perspective that the patients come up against in some of the clinical trials that you oversee.
Jill Manning:
One is that many of these clinical trials are only offered at academic medical centers in big cities and that excludes a lot of individuals who are living in rural areas. And while there's certainly have been efforts to establish satellite sites outside of these urban medical center areas we also have safety concerns with that because sometimes community hospitals or other sites aren't set up to be able to assist, should there be an adverse event
We also have barriers of non-English speakers and the consent process. The consent forms can often be 30 pages long and there are efforts to have translations and short forms and we are doing a lot better and COVID has taught us about the flexibility of interpreter services , which I really do hope it's translated across the board across all sorts of different research projects. But consent forums that are also a real barrier when they're 30 pages and dense
And then we also still have insurance issues. With cancer trials, specifically, insurance plays a lot more into it because corporate sponsors only pay for the true research procedures and they don't cover, an MRI, even if the if the individual needs the MRI for clinical care, the corporate sponsor is not going to be paying for that. So people still need to have adequate insurance coverage for participating in many trials. I think we see that less so in non cancer research.
Lisa Laudico:
You mentioned that so often the consent forms are very complicated medical language and that they need to be translated. They need to certainly make them a lot simpler, but also it's super helpful for the patient, considering the clinical trial to actually have a translator, like a nurse navigator. And usually it's a research trial nurse, depending on the cancer center , but at Mass General Brigham are they dedicating some staff to this effort of making sure that as many patients as possible who could be eligible for a clinical trial are given the kind of time and support for them to actually fully understand, not be so afraid of the clinical trial and, really take them through it in a more personal way.
Jill Manning:
I really hope that this is one of those lessons learned we can apply more broadly post pandemic. When we talk about consent, I always have , my tag, like we're not talking about a form. We're talking about a process. Consent is a process and consent is also a noun. It's not a verb. We do not consent patients. We ask for consent. Consent is something that is given from the individual to the investigators.
And we really need to honor and ensure that there is dignity around this process. This process involves a discussion not just shoving a 30 page consent form to someone and asking them to sign it.
Lisa Laudico:
There are many things that we'd want to have changed about clinical trial design, but we turn to Lianne for the patient perspective, specifically regarding brain Mets as an exclusionary criteria.
Lianne is there anything else on your list of things like, Hey, if I could wave a magic wand and make clinical trials more equitable and easier for patients, what would they be?
Lianne Kraemer:
Oh, God, I have a wishlist so long. That certainly is my number one wish because of how difficult it is to treat brain mets. For somebody who's listening, who isn't as experienced with brain mets, certain drugs that work in your body don't always work in your brain. You have to test out a drug. And so if you don't put it in trial and test it out, we won't know you could FDA approve a drug, but doctors won't be using it for the brain because it hasn't been proved. So we need to study everything in the brain. So that certainly is number one.
I think number two is to not be so restrictive on the Olympians of cancer being your participants in trial. And what I mean by that is don't pick the healthiest of the healthiest for your clinical trial because in reality and that goes back to those exclusionary criteria is if you've had more than so many drugs, you can't be in it. If you've had this drug, you can't be in it. And I understand that there's a balance and that they want to, they also don't want their drug not to be approved because they didn't pick the right people. But in reality, the user of your drug could look like the person you're excluding.
And so if you don't have a good balance in there of the people, who've had lots of treatments and people who've have this accompanying condition who have brain mets, you don't know how they're going to do so you're excluding people from your trial who are going to be users of your drug.
But certainly access and that more oncologists offered their patients. A lot of patients just never get offered clinical trials. If you don't go to a large center where there are clinical trials, if you aren't savvy yourself and understanding, I could be the perfect example, if I had not gone and not been where I was, I could have never landed on those trials. It shouldn't be dumb luck but it really was with me.
