RecruitingDrug trialPTT-936 Alone or in Combination in Patients With Locally Advanced or Metastatic Solid TumorsThis Phase 1/2a study will explore the safety and efficacy of PTT-936, an Alpha Kinase 1 (ALPK1) activator, used alone or in combination with anti-PD-1/L1 therapy in patients with locally advanced or metastatic solid tumors. The study is divided into two parts: Phase 1 (Part A) focuses on determining the pharmaceutically active dosage range and evaluating the safety profile of PTT-936 when administered as a monotherapy. Phase 2a (Part B) will assess the safety and efficacy of PTT-936 combined with anti-PD-1/L1 therapy in patients suitable for anti- PD-1/L1 monotherapy. The study aims to understand how PTT-936, alone or in combination, impacts tumor progression and patients' overall response.
