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).

I-SPY Phase I/Ib (I-SPY-P1) is an open-label, multisite platform study designed to evaluate single agents or combinations in a metastatic treatment setting that may be relevant for breast cancer patients with the overall goal of moving promising drug regimens into the I-SPY 2 SMART Design Trial (NCT01042379) and/or other oncology-based trials in a timely manner.
