A Phase I/II Study of ABSK141 in Patients With Advanced Solid Tumors ( ABSK141-101 )

Официальное название

A Phase I/II, Open-Label Study of ABSK141 to Assess Safety, Tolerability, Efficacy and Pharmacokinetics in Patients With KRAS G12D Mutant Advanced Solid Tumors

Обзор

This is a first-in-human (FIH), exploratory, multicenter, open-label, phase I/II study of ABSK141 in patients with advanced solid tumors to to evaluate safety, tolerability, PK and optimize the dosage.

Подробное описание

The study will start with a dose escalation of oral ABSK141 in patients with advanced solid tumors harboring KRAS G12D mutation to evaluate safety, tolerability, and PK. The expansion part will investigate oral ABSK141 at the recommended doses for expansion (RDEs) to evaluate safety and efficacy among selected tumor types harboring KRAS G12D mutation and optimize the dosage.

The phase II study will further investigate oral ABSK141 at the recommended phase 2 doses (RP2Ds) to evaluate safety and efficacy among selected tumor types harboring KRAS G12D mutation.
