What this Trial Is About

Researchers are evaluating the safety, tolerability, pharmacokinetics, and preliminary anti-tumor activity of a novel oral drug called NKT3964 in adults with advanced or metastatic solid tumors. The study aims to find the recommended dose for further testing and to observe how the drug affects various types of advanced cancers, including ovarian, endometrial, gastric, lung, and breast cancers, particularly those with specific genetic markers like CCNE1 amplification. The study has two main phases: Dose Escalation and Dose Expansion. In the Dose Escalation phase, participants receive increasing doses of NKT3964 to assess safety, side effects, and appropriate dosing. The Dose Expansion phase uses the recommended dose from the first phase to further evaluate the drug’s anti-tumor activity in specific tumor types. Both phases involve oral administration of the study drug, with detailed criteria for patient eligibility based on cancer type, prior treatments, and genetic markers. Participants will undergo regular assessments including physical exams, laboratory tests, imaging scans, and tumor biopsies before and during treatment. Researchers will monitor drug levels in the blood, treatment side effects, and tumor responses using standard criteria over periods ranging from one month to two years. The study also tracks progression-free survival, overall survival, and other measures to understand the drug’s impact and safety profile. Participation involves ongoing monitoring and follow-up visits throughout the study duration.
