Positive data announced from multiple expansion cohorts of Ph 1 trial of fianlimab and Libtayo® (cemiplimab) in advanced melanoma
“After regulatory approvals of our PD-1 inhibitor Libtayo in two advanced non-melanoma skin cancers, we are expanding our efforts in dermato-oncology to address advanced melanoma,” said Israel Lowy, M.D., Ph.D., Senior Vice President, Translational and Clinical Sciences, Oncology at Regeneron. “Combining LAG-3 and PD-1 inhibition has shown promise in advanced melanoma but achieving response rates above 50% has been challenging. In two independent dose expansion cohorts from a Phase 1 clinical trial of patients naïve to PD-1 or PD-L1 inhibitors, our LAG-3 inhibitor fianlimab combined with Libtayo demonstrated greater than 60% response rates. Notably, the safety profile for this combination appears in line with Libtayo monotherapy. A Phase 3 trial in first-line metastatic melanoma is currently enrolling patients, and we look forward to opening additional trials with this combination in the near future.”

“We are deeply disappointed by these results from our Phase 1 trial. Despite continuing to demonstrate differentiated safety as a more combinable ADC, updated efficacy data suggest that treatment with EO-3021 does not meet our bar for success and is insufficient to provide patients a competitive benefit-risk profile compared to
