Evaluating ABT-101 for patients with advanced solid tumors and non-small cell lung cancer

A Phase Ib/II, Open-Label, Multicenter Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Antitumor Activity of ABT-101 in Patients With Advanced Solid Tumors and HER2 Exon 20 Insertions Mutated Non- Small Cell Lung Cancer

Phase1; Phase2 Interventional Anbogen Therapeutics, Inc. · NCT05532696

This study is testing a new drug called ABT-101 to see if it can help people with advanced solid tumors, especially those with certain mutations in non-small cell lung cancer.

What this trial studies

This is a Phase 1b/2 open-label, multicenter study aimed at determining the recommended phase 2 dosage of ABT-101 in patients with advanced solid tumors and assessing its antitumor activity in those with HER2 mutations in non-small cell lung cancer (NSCLC). The study consists of two parts: the first part focuses on dose escalation to identify the optimal dosage while monitoring for dose-limiting toxicities, and the second part evaluates the safety and efficacy of the determined dosage in NSCLC patients. Participants will undergo a screening period, treatment period, and safety follow-up until disease progression or withdrawal criteria are met.

Who should consider this trial

Good fit: Ideal candidates include adults aged 20 and older with advanced solid tumors or HER2 mutated NSCLC who meet specific health criteria.

Not a fit: Patients with active CNS metastases, prior treatment with EGFR or HER2 TKIs, or those with serious infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with HER2 mutated NSCLC and advanced solid tumors.

How similar studies have performed: Other studies have shown promise with similar approaches targeting HER2 mutations, indicating potential for success in this trial.
