Официальное название

Phase 1, First-in-Human, Open-Label Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of TGW101 in Patients With Advanced Solid Tumors

Обзор

The primary objectives of this study are to evaluate the safety and tolerability of TGW101 and determine the recommended dosing regimen(s) for further study. The secondary objectives are to assess pharmacokinetics and preliminary antitumor activity.
