STAT+: The race to catch KRAS, pancreatic cancer’s ‘greasy ball,’ and create the most promising drug in decades
Leanna Stokes had gotten into the habit of asking her oncologist what might be next for her treatment, and for good reason. Stokes, a 36-year-old gymnastics manager from New Rochelle, New York, had received one of the most difficult diagnoses in oncology: metastatic pancreatic cancer. Her oncologist kept mentioning two syllables, KAY-ras, referring to her cancer’s mutation on the KRAS gene. Mutations in this gene can make cancers more aggressive. But for Stokes, it was a possible key to extending her life.
“She always mentioned this — KRAS, KRAS, KRAS,” Stokes said of her oncologist. As Stokes proceeded to receive line after line of chemotherapy, she would remind herself, “It’s there. It’s there. It’s there. Then finally, it was my turn.”
Just a few years ago, such a refrain might have sounded odd to pancreatic cancer experts. For most of the nearly 50 years since KRAS was first discovered, scientists struggled to effectively drug the cancer protein. When Kevan Shokat, a biochemist at University of California, San Francisco, finally discovered how to drug a rare subset of KRAS mutant cancers, the first-generation drugs were a clinical disappointment. For the roughly 1% of pancreatic cancer patients who could receive them, the drugs improved outcomes only marginally, with resistance forming rapidly.
“We did not have a home run on the first effort,” said Channing Der, a pancreatic cancer researcher at the University of North Carolina, Chapel Hill. “It’s fair to say we’ve been disappointed by the durability of the responses.”
But once Shokat had shown it could be done at all, more and more companies jumped into developing drugs for KRAS, with new agents now regularly moving into clinical trials. The company leading the field has been Revolution Medicines, with the drug daraxonrasib, which targets KRAS and related proteins.
This was the drug that Stokes got on her clinical trial. It transformed her life, she said, enabling her to live far longer than most patients with her diagnosis. It’s also generating immense excitement among oncologists and drug developers, who say it heralds a new era for pancreatic cancer medicine and could bring new treatments for other cancer types with KRAS mutations including lung, colorectal, endometrial, and more. Beyond Revolution Medicines, dozens of other companies are also testing promising KRAS inhibitors in the clinic.

Hired someone new and exciting? Promoted a rising star? Finally solved that hard-to-fill spot? Share the news with us, and we’ll share it with others. That’s right. Send us your changes, and we’ll find a home for them. Don’t be shy. Everyone wants to know who is coming and going.
And here is our regular feature in which we highlight a different person each week. This time around, we note that AstronauTx hired Michelle Mellion as chief medical officer. Previously, she held the same role at PepGen and EveryONE Medicines.
But all work and no play can make for a dull chief medical officer.

STAT+: Pharmalittle: We’re reading about a discontinued cancer drug, a Novo security breach, and more
And so, another working week will soon draw to a close. Not a moment too soon, yes? This is, you may recall, our treasured signal to daydream about weekend plans. Our agenda includes promenading with the official mascots, catching another round of live musical vibes here and there, and taking pride in some folks who are dear to us. We also hope to hold yet another listening party, where the rotation will likely include this, this, this, this and this. And what about you? This is a wonderful time of year to sample the many outdoor activities popping up — street fairs, festivals, and all sorts of gatherings can be sampled. If the weather fails to cooperate, though, you could curl up with a good book, sit in front of the telly to take in one or more sporting events, or plan a needed getaway. If none of this strikes your fancy, you could simply park yourself somewhere comfortable for a while and remain zen. Well, whatever you do, have a grand time. But be safe. Enjoy, and see you soon. …
In a rare move, the nonprofit organization Blood Cancer United announced it was buying the remaining supplies of Luvelta, a discontinued investigational cancer drug, STAT reports. As part of the transaction, Blood Cancer United, previously known as the Leukemia & Lymphoma Society, also will acquire the investigational new drug designation and manage the compassionate-use program for children with a rare form of blood cancer, distributing the medication to patients at no cost while supplies last. Sutro Biopharma discontinued development in March 2025 and also eliminated a compassionate use program.
Novo Nordisk identified a security incident in which certain information, including patient data from some clinical trials, was copied externally without authorization from its internal IT systems, Reuters notes. The company said it launched a probe with the assistance of external cybersecurity experts and is in contact with the relevant authorities. The potential categories of personal data affected may include patient ID, year of birth, sex, and health or immunogenicity data among others. Novo did not provide further details, but does not believe the incident will enable any third party to identify participants in its clinical trials.
