Designing Clinical Trials for Patients With Rare Cancers: Connecting the Zebras

Dr. Hope Rugo and Dr. Vivek Subbiah discuss innovative trial designs to enable robust studies for smaller patient populations, as well as the promise of precision medicine, novel therapeutic approaches, and global partnerships to advance rare cancer research and improve patient outcomes. TRANSCRIPT Dr. Hope Rugo: Hello and welcome to By the Book, a podcast series from ASCO that features engaging conversations between editors and authors of the ASCO Educational Book. I am your host, Dr. Hope Rugo. I am the director of the Women's Cancers Program and division chief of breast medical oncology at the City of Hope Cancer Center [in Los Angeles]. The field of rare cancer research is rapidly transforming thanks to progress in clinical trials and treatment strategies, as well as improvements in precision medicine and next-generation sequencing that enable biomarker identification. According to the National Cancer Institute, rare cancers occur in fewer than 150 cases per million each year, but collectively, they represent a significant portion of all cancer diagnoses. And we struggle with the appropriate treatment for these rare cancers in clinical practice. Today, I am delighted to be joined by Dr. Vivek Subbiah, a medical oncologist and the chief of early-phase drug development at the Sarah Cannon Research Institute in Nashville, Tennessee. Dr. Subbiah is the lead author of a paper in the ASCO Educational Book titled "Designing Clinical Trials for Patients with Rare Cancers: Connecting the Zebras," a great title for this topic. He will be telling us about innovative trial designs to enable robust studies for small patient populations, the promise of precision medicine, and novel therapeutic approaches to improve outcomes, and how we can leverage AI now to enroll more patients with rare cancers in clinical trials. Our full disclosures are available in the transcript of this episode. Dr. Subbiah, it is great to have you on the podcast today. Thanks so much for being here. Dr. Vivek Subbiah: Thank you so much, Dr. Rugo, and it is an honor and pleasure being here. And thank you for doing this podcast for rare cancers. Dr. Hope Rugo: Absolutely. We are excited to talk to you. And congratulations on this fantastic paper. It is such a great resource for our community to better understand what is new in the field of rare cancer research. Of course, rare cancers are complex and multifaceted diseases. And this is a huge challenge for clinical oncologists. You know, our clinics, of course, cannot be designed as we are being very uni-cancer focused to just be for one cancer that is very rare. So, oncologists have to be a jack of all trades in this area. Your paper notes that there are approximately 200 distinct types of rare and ultra-rare cancers. And, by definition, all pediatric cancers are rare cancers. Of course, clinical trials are essential for developing new treatment strategies and improving patient outcomes, and in your paper, you highlight some unique challenges in conducting trials in this rare cancer space. Can you tell us about the challenges and how really innovative trial designs, I think a key issue, are being tailored to the specific needs of patients with rare cancer and, importantly, for these trials? Dr. Vivek Subbiah: Rare cancers present a perfect storm of challenges. First, the patient populations are very small, which makes it really hard to recruit enough participants for traditional type trials. Second, these patients are often geographically dispersed across multiple cities, across multiple states, across multiple countries, across multiple zip codes. So, logistics become complicated. Third, there is often limited awareness among clinicians, which delays referrals and diagnosis. Add to that regulatory hurdles, funding constraints, and you can see why rare cancer trials are so tough to execute. To overcome these barriers, we are seeing some really creative novel trial designs. And there are four different types of trial designs that are helping with enrolling patients with rare cancers. The first one is the basket trial. So let us talk about what basket studies are. Basket studies group patients based on shared genetic biomarkers or shared genetic mutations rather than tumor type. So instead of running separate 20 to 30 to 40 trials, you can study one therapy across multiple cancers. The second type of trial is the umbrella trial. The umbrella trials flip that concept of basket studies. They focus on one cancer type but test multiple targeted therapies within it. The third category of innovative trials are the platform studies. Platform trials are another exciting innovation. They allow new treatment arms to be added or removed as the data matures and as the data evolves, making trials more adaptive and efficient. The final category are decentralized tools in traditional trials, which are helping patients participate closer to...
