Expanded Access Program for Promising Pancreatic Cancer Drug

Share

FDA has authorized an expanded access program for an experimental pancreatic cancer therapy from Revolution Medicines, allowing certain patients to receive the drug outside of clinical trials. The agency said it issued a “safe to proceed” letter enabling the company to launch an expanded access treatment protocol for daraxonrasib, a RAS inhibitor being developed for patients with previously treated metastatic pancreatic ductal adenocarcinoma.

The decision came just two days after FDA received the request on 4/28, underscoring what officials described as an effort to accelerate access to investigational therapies for serious and life-threatening conditions.

The therapy has been in the news lately after former Sen. Ben Sasse revealed he’s been taking it.  Late last year, Sasse announced he was diagnosed with Stage 4 pancreatic cancer and given three to four months to live. This week, he indicated that his tumors have shrunk by 76% since he started the treatment, but it has also caused a rash on his skin.

Daraxonrasib is designed to target mutations in the RAS protein, which are commonly found in pancreatic cancer tumors. The drug, also known as RMC-6236, has previously received breakthrough therapy and orphan drug designations from the FDA. Revolution Medicines has indicated it plans to submit an NDA under the agency’s National Priority Voucher pilot program.
