Study of STK-012 Alone and With Other Treatments in Patients With Advanced Lung Cancer and Other Cancers (SYNERGY-101)

March 17, 2026 updated by: Synthekine

A Phase 1/2 Study to Evaluate STK-012 as a Single Agent and in Combination Therapy in Subjects With Front-line Advanced NSCLC and Other Selected Indications

This is a phase 1/2, multicenter, open-label study. The phase 1 portion is a dose escalation and expansion study of STK-012 as monotherapy and in combination therapy in patients with selected advanced solid tumors. The phase 2 portion is a randomized study of STK-012 in combination with standard of care (SoC) pembrolizumab, pemetrexed, and carboplatin versus SoC, in patients with first line, PD-L1 negative, non-squamous, non-small cell lung cancer.
