Latest Breakthroughs on Pancreatic Cancer 2026: New Pancreatic Cancer Drug Nearly Doubles Survival
Pancreatic cancer has long been one of the most feared diagnoses in oncology—aggressive, late-detected, and historically resistant to treatment. But 2026 marks a potential turning point.
Revolution Medicines announced results Monday from a Phase 3 trial showing taking daraxonrasib by mouth daily nearly doubled survival, with patients living 13.2 months compared to 6.7 months on standard intravenous chemotherapy.Patients were eligible for the trial if they had metastatic pancreatic cancer and had already progressed on another treatment. Revolution Medicines CEO Mark Goldsmith called the results "unprecedented," noting no drug has ever demonstrated a survival benefit of more than a year in a Phase 3 pancreatic cancer trial.
What Is Daraxonrasib, and How Does It Work?
Daraxonrasib is an investigational oral medication developed by Revolution Medicines, a clinical-stage oncology company based in Redwood City, California. It belongs to a new class of drugs called RAS (ON) inhibitors.RAS mutations are the central molecular driver of pancreatic cancer, present in about 90% of cases. When functioning normally, RAS proteins act like molecular switches, toggling cell growth on and off. In cancer, these proteins become stuck in the "on" position, continuously signaling cells to grow.
For decades, oncologists considered RAS "undruggable" because the protein’s surface offered no convenient pocket for a drug molecule to bind. Early efforts to inhibit RAS signaling only produced marginal benefits for patients.
Daraxonrasib works differently. It is a multi-selective, non-covalent inhibitor that targets both mutant and wild-type RAS proteins in their active state, blocking the downstream signals that drive tumor growth. This broader targeting strategy is what makes it distinctive, and what makes it challenging to tolerate.
Researchers are already thinking beyond daraxonrasib as a standalone agent. The Phase 3 results of daraxonrasib may be a foundation on which combination strategies can be built. For example, pairing RAS inhibition with chemotherapy or other targeted drugs to push survival further.
A drug that nearly doubles survival in the second-line setting could become the backbone of a first-line regimen if the ongoing trial data support it.

Where Is It in the FDA Approval Process?
Daraxonrasib has not yet been approved for use, but it has accumulated significant momentum. The U.S. Food and Drug Administration has granted the drug several special statuses, including Breakthrough Therapy Designation and Orphan Drug Designation for previously treated metastatic pancreatic cancer with specific mutations, specifically G12 mutations.It was also selected for the FDA Commissioner’s National Priority Voucher program, an initiative launched in June 2025 to accelerate development of therapies aligned with national health priorities. This entitles Revolution Medicines to a faster FDA review when it submits a new drug application, potentially compressing the review timeline from standard periods to a matter of months.
Revolution Medicines said it intends to submit the new drug application to the FDA using this pathway in the near term, following the Phase 3 results announced this week.
A separate Phase 3 trial (RASolute 303) began enrolling patients in April 2026, testing daraxonrasib as a first-line treatment for newly diagnosed metastatic pancreatic cancer. Additional Phase 3 trials are underway in non-small cell lung cancer and other RAS-mutated tumor types.
If Revolution Medicines files its new drug application soon and the FDA grants priority review, approval could plausibly come by late 2026 or early 2027, though no official timeline has been announced. The drug would initially be approved for second-line use, meaning patients whose cancer has already progressed on a first treatment. Broader indications, including first-line use, would depend on data from the ongoing RASolute 303 trial.

Side Effects of Daraxonrasib
Skin toxicity is the signature side effect of daraxonrasib. The drug targets RAS signaling broadly, including in normal skin cells, which rely on RAS pathways for routine regeneration. It interferes with the skin's ability to repair itself. The majority of patients in earlier trials experienced some degree of rash, though fewer than 10% developed a severe reaction. Cases like Sasse’s which involve skin bleeding have been described anecdotally by clinical investigators and are considered uncommon.Managing the rash involves temporary dose interruptions, antibiotics and supportive care. No patients in the pivotal Phase 3 trial discontinued treatment due to rash alone. The drug’s overall safety profile was considered manageable with no new safety signals. Other side effects include nausea, fatigue and pain.
Experimental KRAS G12D Pancreatic and Lung Cancer Treatment
Another study, co-led by UCLA suggests a potential new treatment approach for KRAS G12D, a key driver of lung and pancreatic cancer with few current treatment options. A first-in-human clinical trial led by an international team of researchers and published in the New England Journal of Medicine (2026) found that setidegrasib, an investigational targeted therapy drug designed to eliminate a key cancer-driving protein called KRAS G12D, shows encouraging early activity in patients with advanced lung and pancreatic cancers.The therapy shrank tumors in some patients and delayed disease progression, marking a potential step forward for cancers with few targeted treatment options.
Setidegrasib is designed to attack a mutation known as KRAS G12D, which helps cancer cells grow and survive. Unlike most targeted therapies, which work by blocking a cancer-driving protein, setidegrasib degrades and removes the abnormal KRAS protein from inside cancer cells.
The KRAS G12D mutation is one of the most common genetic drivers of pancreatic ductal adenocarcinoma, occurring in about 40% of patients. It is also found in about 5% of patients with non–small-cell lung cancer.
Despite its prevalence, KRAS G12D has historically been considered extremely difficult to target because the structure of the protein makes it hard for drugs to effectively bind to it.
While therapies have recently been developed for a related mutation, KRAS G12C, no approved treatments currently exist for KRAS G12D, leaving a major unmet need for patients with these cancers.
The Phase I clinical trial was conducted across 28 centers in five countries and included 203 patients whose cancers had already progressed after prior treatments. Researchers tested escalating doses of setidegrasib to evaluate safety and early signs of activity and identified 600 mg once weekly administered intravenously as the recommended dose for further study based on safety, drug activity, and early signs of efficacy. The therapy demonstrated early antitumor activity in both advanced lung and pancreatic cancer. Among the 66 patients (45 with lung cancer and 21 with pancreatic cancer) who received the 600-mg dose:

- In pancreatic ductal adenocarcinoma, 24% of patients experienced tumor shrinkage, with a median overall survival of 10.3 months in heavily pretreated patients.
Understanding Pancreatic Cancer: The Deadliest of the Major Cancers
Pancreatic cancer accounts for roughly 3% of all cancer diagnoses in the United States but ranks as the third leading cause of cancer death. The five-year survival rate is approximately 13%.The disease is almost never caught early. It produces few specific symptoms in its initial stages. Symptoms it does cause — like vague abdominal discomfort, back pain, unexplained weight loss and fatigue — can easily be attributed to other conditions. Jaundice, or yellowing of the skin, can occur in some patients but typically signals that the tumor has grown large enough to obstruct the bile duct.
There is no population-level screening for pancreatic cancer, so approximately 80-90% of patients are diagnosed with non-resectable disease (50-55% metastatic, 30-35% locally advanced) when surgery — the only potentially curative treatment — is no longer an option.
Pancreatic cancer has resisted treatment for reasons because of its biology. The tumor is surrounded by dense fibrous tissue that acts as a physical barrier, limiting the penetration of chemotherapy and immune cells. The local environment also suppresses immune activity. This is why immunotherapy, which has transformed outcomes in lung cancer and other cancer, has largely failed in pancreatic cancer.
