A Phase Ib Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Efficacy of AMG 193 Alone or in Combination with Other Therapies in Subjects with Advanced Thoracic Tumors with Homozygous MTAP Deletion
Details
The study aims to determine maximum tolerated dose (MTD) or recommended combination dose of the MTA-cooperative PRMT5 inhibitor AMG 193 administered in combination with other therapies in adult participants with metastatic or locally advanced methylthioadenosine phosphorylase (MTAP)-deleted thoracic tumors. The study also aims to determine the safety profile of AMG 193 administered in combination with other therapies in adult participants with metastatic or locally advanced MTAP-deleted thoracic tumors.
