Официальное название

Phase I/II Study of the Selective RET Inhibitor TAS0953/HM06 in Patients With Advanced Solid Tumors With RET Gene Abnormalities

Обзор

Phase 1 and 2 trial to study the safety, pharmacokinetics, and efficacy of TAS0953/HM06 in patients with advanced solid tumors with RET gene abnormalities. Phase 1 aims to determine the Maximum Tolerated Dose (MTD) and identify the Recommended Phase 2 Dose (RP2D) to be used in phase 2.
