About

This is an open-label, multicenter, Phase 1, ascending dose escalation study of QL1706 in subjects with advanced malignant tumor. The study will be conducted in 2 parts. Part 1 of the study will be a dose escalation evaluation to determine the maximum tolerated dose (MTD) and to establish a recommended Phase 2 dose (RP2D) of QL1706. This study purpose is to describe the safety and tolerability, to assess Pharmacokinetics (PK) and immunogenicity, and to preliminarily assess the anti-tumor activity of QL1706 in subjects with advanced malignant tumor. Part 2 of the study will further characterize the PK parameters for QL1706 in subjects with advanced malignant tumor.

Full description

The study was divided into screening/baseline, treatment and follow-up periods. Safety monitoring will be conducted throughout the study period. DLT will be determined 21 days (1 cycle) after the first administration of QL1706 based on the occurrence of AE during the treatment period.

Open-label Dose Escalation and Expansion Study of QL1706

Experimental group

Description:

Part 1 (Dose escalation): QL1706 will be administered in sequential cohorts each receiving 1 of 4 doses of QL1706 on day 1 of every 21-day cycle (3 weeks) via IV infusion. Dose escalation will continue until an MTD is reached. Part 2 (Dose Expansion): The PK parameters of QL1706 will be tested at 2-3 doses determined during the dose-escalation phase in subjects with advanced malignant tumor cohorts.
