FDA OKs RevMed’s Promising Pancreatic Cancer Drug

Share

FDA has approved Revolution Medicines’ Rasonque (daraxonrasib), a RAS inhibitor for the most common form of pancreatic cancer — providing a new treatment option to patients with advanced pancreatic cancer 6.5 months ahead of the user fee review action target date. The once-a-day tablet “targets multiple forms of a protein called RAS, a key driver of tumor growth in most patients with pancreatic adenocarcinoma, which arises from cells lining the ducts of the pancreas,” an FDA release says.

The approval covers treating adults with metastatic pancreatic adenocarcinoma who have received at least one prior systemic therapy or are not candidates for multiagent systemic therapy. “Despite representing roughly 3.2% of all cancer diagnoses, pancreatic adenocarcinoma accounts for a disproportionately high share of cancer deaths, owing to its typically late detection, aggressive disease course, and historically limited treatment options,” the agency says.

The approval, which came under the Commissioner’s National Priority Voucher pilot program, was based on data from a study involving 500 adults with previously treated metastatic pancreatic adenocarcinoma. Rasonque was shown to have a median overall survival of 13.2 months compared to 6.7 months for standard chemotherapy, FDA says.

The most common side effects of the drug are rash, diarrhea, stomatitis, nausea, fatigue, vomiting, abdominal pain, edema, decreased appetite, and hemorrhage.

Earlier this year, FDA authorized an expanded access program for the therapy, allowing certain patients to receive the drug outside of clinical trials. Rasonque has also 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. Recently, he indicated that his tumors have shrunk by 76% since he started the treatment.
