Our Track Record
One of the key priorities of our center is to provide access to new therapies for RAS-driven cancers through clinical trial participation. Our portfolio of clinical trials for patients with KRAS-driven cancers is large and diverse, spanning different cancer types, different stages of disease, and different phases of clinical investigation. We also offer clinical trials that include combinations of therapies to further improve clinical outcomes with existing KRAS-targeted therapies.
Dana-Farber investigators have been actively driving the development of new KRAS inhibitors, including the KRASG12C inhibitor adagrasib which is now FDA approved for patients with previously treated, KRASG12C-mutant lung cancer and KRASG12C-mutant colorectal cancer. There are also newer promising therapies like RMC-6236, a multi-selective RAS inhibitor which is being evaluated in a randomized phase 3 trial for patients with previously treated advanced pancreatic cancer.
Research Areas of Interest
Clinical Trials
Dana-Farber boasts one of the largest portfolios of clinical trials investigating novel therapies for cancer patients, including therapies designed specifically for patients with KRAS-mutant cancers. The new RAS Center will work closely with investigators and with industry partners to identify the most promising clinical trials to open at Dana-Farber, based on mechanism of action, preclinical data, and the evolving treatment landscape.
Focus on Drug Resistance
While early therapeutic strategies targeting KRAS have shown promising results, some patients do not respond, and some patients who do respond eventually develop drug resistance leading to worsening disease. Dana-Farber investigators have played a major role in not only developing new targeted therapies but also discovering mechanisms of resistance to these therapies. Understanding why cancers become resistant is critical to developing new and more effective therapeutic strategies in the clinic.
Investigators in the RAS Center have a special interest in resistance to RAS-targeted therapies. Our investigators published one of the first reports on resistance to KRASG12C inhibitors in the New England Journal of Medicine. In this study, resistant cancers from patients with KRASG12C-mutant lung and colorectal cancers were comprehensively profiled at the genomic level to discover multiple different mechanisms of resistance to adagrasib. We also recently reported the discovery of mechanisms of resistance to KRASG12C and KRASG12D inhibitors in clinical samples and preclinical models of pancreatic cancers. These and other studies have revealed fundamental insights into the biology of resistance and provided the scientific basis for developing new combinatorial strategies designed to overcome resistance.
At present, there are no effective therapeutic strategies that can overcome resistance in KRAS-mutant cancers. Based on the latest research, we are pursuing many different combination strategies in the clinic, including combinations with cytotoxic chemotherapy, immunotherapy such as PD-1/PD-L1 inhibitors, and other targeted therapies such as Ras/MAPK pathway inhibitors and PRMT5 inhibitors. Our clinical trials may be industry sponsored and involve close collaboration with both the drug manufacturer and other academic sites. Other trials and studies may be investigator-initiated based on preclinical data developed at Dana-Farber using various cancer models such as patient-derived xenograft models, organoid models, or genetically engineered mouse models.
Patients who are eligible for these clinical trials and research studies on resistance include those with RAS-mutant cancers who have previously received a RAS-targeted therapy. In some cases, these trials and studies may also include patients who have never received a RAS-targeted therapy to investigate whether a new approach may be able to prevent the development of resistance.
