Study Description
Brief Summary:

This study has two parts: dose escalation and dose expansion.

The primary objectives are:

  • For Dose Escalation, to assess the safety and tolerability of U3-1402 in the study population and to determine the recommended dose for expansion of U3-1402 in the study population
  • For Dose Expansion, to assess the safety and tolerability of U3-1402 in the study population

The number of treatment cycles is not fixed in this study. Participants will continue study treatment for 36 months unless they decide not to (withdraw consent), their disease gets worse [progressive disease (PD)], or side effects become unacceptable (unacceptable toxicity) or other stopping reasons have been met.

U3-1402 consists of an antibody component (patritumab, U3-1287) covalently conjugated to a drug-linker (MAAA-1162a) containing a drug component (MAAA-1181a)
