Clinical Trial Summary

A Phase 1b/2, open-label, multicenter study to determine the recommended phase 2 (RP2D) of ABT-101in solid tumor and to explore antitumor activities of ABT-101 in patients with HER 2 mutated non-small cell lung cancer (NSCLC)

Description:

This study will be conducted in two parts:

Part 1: Dose- Escalation, Phase 1b, is designed to determine the RP2D. Patients with solid tumor will be enrolled into a dose finding study scheme with the assessment of dose-limiting toxicities (DLTs). DLT assessment will be conducted during treatment cycle 1

Part 2: Dose- Expansion, Phase 2, will evaluate the safety and efficacy of ABT-101 at the dosage and dosing regime determined in Phase 1b. Phase 2 will enroll NSCLC patients with HER2 mutations

Study participation for all patients includes screening period, treatment period and safety/ follow-up period. Patient will received study treatment until progressive disease or any other discontinuation or withdrawal criterion is met
