MapKure, BeiGene and SpringWorks Present Clinical Data on BGB-3245, a Selective Next-Generation B-RAF Inhibitor, in Adult Patients with Advanced or Refractory Solid Tumors

MapKure, BeiGene and SpringWorks Therapeutics, today announced that they will present updated clinical data from the Phase 1a/1b study of BGB-3245, an investigational, selective RAF dimer inhibitor, in adult patients with advanced or refractory solid tumors harboring MAPK pathway aberrations. The data are being presented today in an oral presentation at the American Association for Cancer Research (AACR) Annual Meeting 2023, taking place in Orlando, Florida.

“The promising data we are sharing at AACR demonstrate the value of our next-generation RAF dimer inhibitor, BGB-3245, as a monotherapy in patients with MAPK pathway-altered cancers, especially its potential to address key primary and resistance gene alterations that are currently unaddressed by approved therapies,” said Lusong Luo, Ph.D., Acting CEO of MapKure and Senior Vice President, External Innovation at BeiGene. “We believe that our early clinical data supported the advancement into our selected expansion cohorts which are now underway.”

“SpringWorks is committed to developing genomically-targeted therapies for patients with cancer and our MAPK directed portfolio is a cornerstone of our efforts. In particular, we are encouraged by the promising activity BGB-3245 is showing in patients with MAPK pathway aberrations,” said Saqib Islam, CEO of SpringWorks. “We and our partners are excited by the advancement of this program and are eager to continue making strides to benefit patients in significant need of new therapeutic options.”
