About this trial

This is a multicenter, open-label, dose-escalation/dose-expansion, Phase Ib/II study to evaluate the safety, tolerability, PK characteristics, and preliminary anti-tumor efficacy of HDM2017 combination therapy in participants with advanced CRC. The study is divided into two periods: dose escalation (Phase Ib) and dose expansion (Phase II). Phase Ib of this study is a dose-finding study of different HDM2017 combination therapies. The Phase II study will be conducted at a dose determined to be safe and potentially effective in Phase Ib.

Trial outcomes

Primary outcomes

1

Maximum Tolerated Dose (MTD)

The MTD will be determined using DLTs

Time frame
30 days after the last dose of IMP
2

Recommended Phase 2 Dose (RP2D)

The RP2D will be determined using dose limiting toxicities (DLTs) and all other available study data

Time frame
30 days after the last dose of IMP
3

Type, incidence and severity of Adverse Events

Safety and tolerability profile assessed by the Common Terminology Criteria for Adverse Events v6.0

Time frame
30 days after the last dose of IMP
4

Objective Response Rate (ORR)

ORR is defined as the proportion of subjects with BOR response of CR or PR (based on RECIST Version 1.1).

Time frame
From date of first-dosing until the date of first documented progression or date of 30 days after the last dose of IMP, whichever came first, assessed up to about 12 months

Secondary outcomes

1

Disease control rate (DCR)

Time frame
30 days after the last dose of IMP
2

Duration of Response (DoR)

Time frame
From date of confirm ORR until the date of first documented progression, assessed up to about 36 months
3

Progression Free Survival (PFS)

Time frame
From date of first-dosing/randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to about 36 months
4

Overall survival (OS)

Time frame
From date of first-dosing/randomization until the end of the trail or date of death from any cause, whichever came first, assessed up to about 48 months
