The drugmaker Erasca said Monday that its RAS-targeting pill shrank tumors in 40% of patients with advanced pancreatic cancer and 62% of patients with advanced non-small cell lung cancer, results that the company said exceeded its expectations. 

The new data, collected from studies done in the U.S. and China, are still preliminary. However, Erasca said the clinical benefit and tolerability of its drug, called ERAS-0015, compared favorably to daraxonrasib, a similar RAS-targeting drug from Revolution Medicines that recently showed a doubling of overall survival in patients with advanced pancreatic cancer. 

“I’m excited about both datasets, but I think lung is more definitive at this point. The pancreatic results are maturing, but are very, very promising,” Erasca CEO Jonathan Lim told STAT. “All options are on the table.”
