This one is special.
This is the hottest paper of 2026 and potentially in the history of pancreatic cancer.
Let’s dive in.
RASolute 302: Daraxonrasib vs investigator’s choice chemotherapy in previously treated metastatic pancreatic cancer
Abstract LBA5 (soon!)
Presentation: May 31, 2026, 3:21-3:33 PM CDT
For decades, pancreatic cancer has been where good ideas go to die.
We have optimized chemotherapy. We have sequenced chemotherapy. We have celebrated modest gains.
But the central driver of PDAC has always been sitting there in plain sight:
RAS.
More than 90% of pancreatic cancers have oncogenic RAS mutations, and until recently, we had essentially nothing direct to do about it.
Daraxonrasib is an oral RAS(ON) multiselective inhibitor targeting the active GTP-bound state of mutant and wild-type RAS.
And in RASolute 302, it delivered.
Quick hits:
📌 Phase 3 international randomized trial 500 patients with previously treated mPDAC Daraxonrasib vs investigator’s choice chemotherapy
🧬 RAS G12 population
91.8% of patients had RAS G12 mutations
📈 OS in RAS G12 population
13.2 vs 6.6 months
HR 0.40
P<0.001
📈 OS in overall population
13.2 vs 6.7 months
HR 0.40
P<0.001
📊 PFS in RAS G12 population
7.3 vs 3.5 months
HR 0.45
P<0.001
📊 PFS in overall population
7.2 vs 3.6 months
HR 0.49
P<0.001
🔥 12-month OS
Overall population: 53.2% vs 17.3%
⚠️ Toxicity matters, but this was not just more efficacy for more toxicity
Grade ≥3 AEs: 61.8% vs 69.6%
TRAEs leading to discontinuation: 1.2% vs 11.2%
This is the kind of survival curve we almost never get to see in pancreatic cancer.
This validates RAS(ON) inhibition in the most RAS-addicted major cancer. It takes a target we have talked about for decades and turns it into a clinically meaningful survival benefit in a randomized phase 3 trial.
The next questions come fast: 1L combinations, maintenance, perioperative disease, sequencing, resistance, toxicity management, and whether this becomes a new backbone.
RAS is here, and it couldn’t have come sooner.

People who don't follow cancer research often ask me why we haven't cured cancer. That perception masks a wonderful reality: We make amazing, stepwise progress every year, and the result is that many people live much longer today than they would have previously.
Right now we're in the thick of the annual meeting of the American Society of Clinical Oncology, the biggest research meeting on new cancer medicines, and this morning a bunch of really important studies dropped. I'm going to review them here.
This first image is the result for daraxonrasib, a treatment for pancreatic cancer that is generating consdirable excitement. The green line is the probability of living for patients who got the new drug; the gray one is the chemo control group.
If you follow cancer drugs, a chart like this will make your breath hitch a little. I'm going to review these and some other data here.
Presented at #ASCO26:
Among patients with previously treated metastatic pancreatic ductal adenocarcinoma, the RAS(ON) inhibitor daraxonrasib led to significantly longer overall survival and progression-free survival than chemotherapy. Full phase 3 RASolute 302 trial results: nej.md/4nWaxvM

ALT Graph from a study published in the New England Journal of Medicine on daraxonrasib versus chemotherapy for metastatic pancreatic cancer. The x-axis represents months, and the y-axis shows the percentage of patients alive. Two lines indicate survival rates: daraxonrasib (blue) and chemotherapy (gray). The bottom section lists patients at risk over time. Title and journal logo are included.

Always enjoy my time at #GEST! Got to present our work on a AI prototype for #PAE and see our undergrad’s educational exhibit related to Y-90 for HCC.
Also cool to see all the demos, specially the AR one. It looks like these glasses are here to stay 🥽

As always, the best part of these conferences are the people!! Meeting other trainees and seeing so many cool girls interested in IR fills my heart 🫰🏽
