Medico’s Mouse‑Only “Cure” Sparks Hype and Scrutiny Over Pancreatic Cancer Trial

Spanish biochemist Mariano Barbacid announced a “cure” for pancreatic cancer based on a triple‑drug therapy that regression‑tested 45 mice; the work, published in PNAS after Nature declined to publish, has not been tested in humans or metastases. The flashy public rollout and patent push by Barbacid’s Vega Oncotargets drew patient inquiries and criticism from CNIO colleagues for overclaiming and conflicts of interest. Independent experts urge cautious optimism, noting the (promising but early) preclinical results and emphasizing that mouse outcomes rarely translate to human cures, with human trials years away and more work needed on safety and efficacy.

Three-drug combo eliminates pancreatic tumors in mice, signaling potential human therapies

A triple-drug regimen that targets three cancer-growth pathways—KRAS, its related pathway, and STAT3—completely eradicated pancreatic tumors across three mouse models, prevented tumor recurrence for about seven months, and showed no significant toxicity in mice. The treatment uses afatinib, daraxonrasib, and a novel STAT3 inhibitor. While the results are promising, researchers caution that mouse findings may not translate to humans and plan further drug development and clinical testing across diverse KRAS mutations.

Triple KRAS Pathway Blockade Drives Complete Regression of Pancreatic Tumors in Preclinical Tests

Spanish researchers report a three-drug combo (RMC-6236/daraxonrasib, Afatinib, SD36) that simultaneously targets RAF1 (KRAS downstream), EGFR (upstream) and STAT3 signaling, producing complete regression of pancreatic tumors in orthotopic mouse models and patient-derived tissues with no resistance for more than 200 days, suggesting potential clinical trials for pancreatic ductal adenocarcinoma.

Triple-therapy breakthrough halts pancreatic tumors in mice

Spanish CNIO researchers report that a triple combination therapy—an experimental KRAS inhibitor, an existing lung-cancer drug, and a protein degrader—caused long-lasting regression and prevented recurrence of pancreatic ductal adenocarcinoma in three mouse models, a potential path toward new clinical trials, though optimization for patients and trials is not yet planned.

Revolutionary Cancer Drug Enhances Radiation Therapy Effectiveness

UC San Francisco scientists have developed a targeted radiation therapy that combines a cancer drug with a radioactive antibody to selectively destroy cancer cells, minimizing damage to healthy tissue. This approach, which effectively eliminated lung and bladder tumors in mice, uses a drug to flag cancer cells and a radioactive antibody to deliver precise radiation, potentially overcoming tumor resistance. The team is working on adapting this method for broader patient use by developing antibodies that account for individual cellular differences.

Unveiling New Strategies to Target and Inhibit KRAS in Cancer

Researchers have created multiple global atlases of inhibitory allosteric communication in KRAS, a protein involved in signaling pathways and a known therapeutic target. By quantifying the impact of over 26,000 mutations on the folding and binding of KRAS, the study identified allosteric sites that can be targeted for inhibition. The central beta sheet of KRAS was found to be particularly effective in allosteric propagation, and multiple surface pockets were validated as allosterically active, including a distal pocket in the C-terminal lobe of the protein. This research provides insights into the regulatory and therapeutic potential of allosteric modulation in proteins.

Roche's KRAS Drug Shows Promising Results in NEJM Study

Roche has published Phase I data on its KRAS G12C inhibitor in the New England Journal of Medicine, showcasing its potential as a monotherapy across various cancers. The study included 137 patients with non-small cell lung cancer, colorectal cancer, and other solid tumors, as Roche aims to catch up with and surpass competitors Amgen and Mirati in the KRAS race.
