A Study With NKT3964 for Adults With Advanced/Metastatic Solid Tumors
Trial Parameters
Brief Summary
The goal of the Dose Escalation phase of the study is to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity to determine the preliminary recommended dose for expansion (RDE) of NKT3964 in adults with advanced or metastatic solid tumors. The goal of the Expansion phase of the study is to evaluate the preliminary anti-tumor activity of NKT3964 at the RDE based on objective response rate (ORR) and determine the preliminary recommended Phase 2 dose (RP2D).
Eligibility Criteria
Inclusion Criteria: \- Must have a pathologically confirmed advanced and unresectable or metastatic solid tumor listed below with documented disease progression on last standard treatment. Part 1 only: subjects must be refractory to, or intolerant of existing therapy(ies) known to provide clinical benefit for their condition. Dose Escalation: 1. Ovarian cancer 2. Endometrial cancer (only endometrioid subtype will require CCNE1 amplification) 3. Gastric, gastroesophageal junction (GEJ) or esophageal adenocarcinoma with CCNE1 amplification 4.

Other solid tumors with CCNE1 amplification Dose Expansion: Part 2A: HR+ and HER2- breast cancer that is locally advan
