Verastem Oncology announced positive preliminary data from the ongoing TARGET-D 101 Phase 1/2 clinical trial evaluating VS-7375, an investigational oral KRAS G12D inhibitor, with best-in-class potential, in patients with advanced KRAS G12D-mutated solid tumors. The data demonstrate encouraging clinical activity along with a favorable safety and tolerability profile across multiple dose levels and tumor types, including metastatic pancreatic ductal carcinoma, metastatic colorectal cancer, and advanced non-small cell lung cancer. "VS-7375 has demonstrated anti-tumor activity across multiple dose levels and tumor types, encouraging signals from rational combination strategies, and a favorable safety profile that improves meaningfully beyond the first treatment cycle, underscoring its potential to be not only the best-in-class oral KRAS G12D inhibitor, but also the preferred treatment option for patients with KRAS-G12D-mutated cancers," said Michael Kauffman, M.D., Ph.D., president of development at Verastem Oncology. "Importantly, VS-7375 has demonstrated compatibility with both anti-EGFR therapy and standard-of-care chemotherapy, supporting the broad development strategy we are pursuing across pancreatic, non-small cell lung, and colorectal cancers. As patient follow-up matures in the TARGET-D 101 study, we are enrolling patients in our three Phase 2 registration-directed studies. We look forward to sharing additional data on VS-7375 in patients with KRAS G12D-mutated cancers later this year."

Verastem Oncology announced positive updated safety and efficacy results from the RAMP 205 Phase 1b/2a Recommended Phase 2 Dose cohort of 29 patients evaluating avutometinib plus defactinib in combination with gemcitabine and nab-paclitaxel in first-line metastatic pancreatic ductal adenocarcinoma. KRAS is mutated in more than 90% of pancreatic cancers, making it a key driver of tumor growth. The RAMP 205 trial was designed to evaluate whether simultaneous inhibition of KRAS-driven signaling and FAK-mediated resistance pathways, in combination with standard-of-care chemotherapy, could improve outcomes for patients living with metastatic pancreatic cancer.

The company states: "Verastem Oncology announced that the first patient has been dosed in the TARGET-D 201 Phase 2 registration-directed trial evaluating VS-7375, an investigational oral KRAS G12D inhibitor with best-in-class potential, to treat patients with KRAS G12D-mutated metastatic pancreatic ductal carcinoma. TARGET-D 201 is a Phase 2, open-label, multi-center study to evaluate VS-7375 at 900 mg once daily both as monotherapy and in combination with full-dose cetuximab in patients with second-line metastatic pancreatic ductal carcinoma. The study is also evaluating VS-7375 900 mg and cetuximab in the first-line mPDAC setting, representing a potential chemotherapy-free frontline regimen. FDA Fast Track Designation was previously granted for VS-7375 for the treatment of KRAS G12D-mutated advanced or metastatic pancreatic cancer in both the first- and second-line treatment settings. In June 2025, Verastem initiated TARGET-D 101, its Phase 1/2 dose escalation, dose expansion, and combination clinical trial evaluating VS-7375 in patients with advanced KRAS G12D-mutated pancreatic, non-small cell lung, colorectal, and other solid tumor cancers. Enrollment is ongoing with monotherapy dose escalation progressing from 400 mg through 900 mg QD doses without dose-limiting toxicities or major safety concerns observed to date. The study is currently evaluating a 1200 mg QD monotherapy dose and a 900 mg QD dose of VS-7375 in combination with full-dose cetuximab, as well as combinations with either gemcitabine plus nab-paclitaxel or carboplatin/pemetrexed/pembrolizumab."
