Dose Escalation
Experimental
GQ1005 will be administered intravenously every 21 days. Dose Escalation will be guided by Bayesian Optimal Interval (BOIN) Design.
Multiple dose grouping
干预措施: GQ1005 (Drug)
Dose Expansion
Experimental
GQ1005 at the recommended phase II dose (RP2D) will be administered intravenously every 21 days. Dose expansion will further evaluate the MTD or RP2D in different types of malignant solid tumor in four cohorts.
干预措施: GQ1005 (Drug)
结局指标
主要结局
Dose Limiting Toxicities (DLTs)
时间窗: From first dose to the end of Cycle 1, 21 days
Adverse events will be assessed using NCI CTCAE version 5.0 and will be evaluated by the investigator and the sponsor for the eligibility of DLT.
Incidence and Severity of Adverse Events (AEs)
时间窗: Up to 2 years
Incidence and severity of Treatment-emergent adverse events, treatment-related adverse events and serious adverse events, according to NCI-CTCAE Version 5.0 (The number of participants who had treatment-related side effects in population who had received one therapy at least).
Maximal Tolerance Dose (MTD) or recommended phase II dose (RP2D)
时间窗: After each cohort completes the DLT observation period (Day 1 to Day 21 after the first dose of study treatment) or has a DLT or becomes not DLT-evaluable
The SRC will also determine the MTD/RP2D based on the totality of data for all tested dose levels.
