QL1604 Monotherapy for dMMR or MSI-H Advanced Solid Tumors
December 5, 2022 updated by: Qilu Pharmaceutical Co., Ltd.
A Single-arm, Multi-center, Phase Ⅱ Clinical Study to Evaluate Efficacy and Safety of QL1604 Monotherapy for the Treatment of Unresectable or Metastatic Mismatch Repair Deficient (dMMR) or Microsatellite Instability-high (MSI-H) Solid Tumors That Failed to Respond to Standard Therapy
In this study, patients with previously-treated locally-advanced or metastatic mismatched repair deficient (dMMR) or microsatellite instability-high (MSI-H) colorectal carcinoma (CRC) and other solid tumors will be treated with QL1604 monotherapy.
