Pancreatic cancer patient Ben Sasse sees ‘massive’ tumor reduction with experimental new drug
Pancreatic cancer is difficult to diagnose early because there are generally no symptoms — or only subtle gastrointestinal symptoms — until it is already widespread, according to Dr. Marc Siegel, Fox News senior medical analyst.
“This is the first-of-its-kind targeted therapy for pancreatic cancer,” Siegel, who also was not involved in the research or the senator’s treatment, told Fox News Digital. “The drug is in the final stages of clinical trials, where it has been shown to double the survival of those previously treated for metastatic pancreatic cancer.”

Mukherjee noted that the survival boost seen in the trial is a “big difference” for a disease that typically has much shorter survival times.
“From my perspective, as someone who treats pancreatic cancer every day, daraxonrasib is the first targeted pill in this disease that truly feels like a step change rather than a small incremental improvement,” he said.
“It opens the door to much more personalized strategies going forward. For a cancer where progress has been painfully slow, it could reshape how we care for patients with advanced disease.”

While current chemotherapy options can shrink pancreatic tumors and help people live longer, they are “tough,” Mukherjee noted — “and once they stop working, our options are limited and survival is usually measured in just a few more months.”
Early data also suggests that when daraxonrasib is combined with standard chemotherapy as the first treatment, there is more shrinkage of tumors and more patients doing well at six months than they typically would only with chemotherapy.

If the drug is approved, it will likely become an important option for patients when standard chemotherapy stops working, Mukherjee suggested.
“Ongoing trials are now asking whether it should also be used as part of the very first treatment plan,” he added.

Although the drug is described as “well-tolerated” compared to chemotherapy, the doctor noted that, like any strong cancer drug, daraxonrasib has side effects.
“The ones we see most often include rash, diarrhea, mouth sores and fatigue, with patients needing regular blood tests and close follow‑up while on treatment,” Mukherjee said.

In the clinical trials, most of these problems have been managed by adjusting the dose or adding supportive medications.
“The limitations are important to be transparent about — it is still not yet FDA‑approved, and it is not a cure,” Mukherjee noted.

“Over time, most cancers will eventually find ways to grow around the drug.”
