Study of ADCT-502 in Patients With Advanced Solid Tumors Withhuman Epidermal Growth Factor Receptor-2 (HER2) Expression

Trial ID or NCT#

NCT03125200

Status

not recruiting iconNOT RECRUITING

Purpose

This study evaluated ADCT-502 in participants with Advanced Solid Tumors with HER2 Expression. Participants participated in a dose-escalation phase (Part 1) and were due to participate in the dose expansion phase (Part 2). In Part 2, patients were due to receive the dose level identified in Part 1, but the study was terminated prior to the beginning of Part 2.

Official Title

A Phase 1, Open-Label, Dose-Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Antitumor Activity of ADCT-502 in Patients With Advanced Solid Tumors With HER2 Expression
