About this study
Official title: A Multicenter, Open-Label, Phase I/Ⅱ Clinical Study to Evaluate CM529D1 in the Treatment of Participants With Advanced Solid Tumors
This is interventional study to evaluate the safety and tolerability, pharmacokinetics, immunogenicity, and preliminary efficacy of CM529D1 in participants with advanced solid tumors.
- Conditions
- Advanced Solid Tumors
- Being tested
- CM529D1
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CM529D1Biological
CM529D1 will be administered intravenously once every 3 weeks (Q3W) in 6 predetermined dose levels.
CM529D1Biological
CM529D1 will be administered intravenously once every 3 weeks (Q3W) in one or more potential recommended phase 2 dose(RP2D).
CM529D1Biological
CM529D1 will be administered intravenously once every 3 weeks (Q3W) in different types of solid tumor cohorts.
| Study group | Role | What they receive |
|---|---|---|
| Phase I dose escalation | Experimental | Not described Receives: Biological: CM529D1 |

What is being measured
The primary outcome is the main question the study is designed to answer.
Dose Limiting Toxicity (DLT)-Phase I dose escalation
DLT is defined as a toxicity occurring during the DLT observation period.
Measured: First cycle (21 days)
Incidence of adverse events (AEs), serious adverse events (SAEs), and specific laboratory abnormalities-Phase I dose escalation
An adverse event is defined as any unfavorable medical event that occurs in a subject after receiving the investigational drug, which will be graded according to Common Terminology Criteria for Adverse Events (CTCAE) v6.0 criteria.
Measured: Through study completion, an average of 2 years
The Recommended Phase 2 Dose (RP2D)Phase I dose expansion
RP2D is defined as the dose selected at the conclusion of Phase 1 dose- expansion, based on the integrated assessment of safety, tolerability, pharmacokinetics, and preliminary antitumor activity, and recommended for further evaluation in Phase 2 studies.
Measured: Through study completion, an average of 2 years
Objective response rate (ORR)-Phase II
ORR is defined as the proportions of subjects with a complete response (CR) and partial response (PR). ORR will be assessed by investigator according to Response Evaluation Criteria in Solid Tumors( RECIST) v1.1.
Measured: Through study completion, an average of 2 years
