About this trial
This is a first-in-human, open-label, multicenter Phase I/II study of MHB042C in patients with advanced solid tumors. The study was designed to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of MHB042C monotherapy.

Treatments tested in this trial
MHB042C for Injection
DrugIV administration of MHB042C Q2W or Q3W; Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and confirmed disease progression.
Treatment groups
200 Participants
are divided into 2 treatment groupsGroup A: MHB042C (Phase I: Dose escalation)Experimental treatment 1 intervention
Group B: MHB042C (Phase II: Dose expansion)Experimental treatment 1 intervention
Trial outcomes
Primary outcomes
1
(Dose-Escalation Stage): Dose-Limiting Toxicity (DLT) and Maximum tolerated dose (MTD) for MHB042C
To determine the MTD for further evaluation of IV administration of MHB042C monotherapy in subjects with advanced solid tumors.
Time frame
Up to day 21 from the first dose for Q3W administration.2
(Dose-Expansion Stage): Objective tumor response (ORR) determined by investigators according to RECIST v1.1
To determine the recommended Phase II dose (RP2D) of MHB042C for the treatment of selected patients with advanced solid tumors based on the safety and efficacy results from all enrolled subjects.
Time frame
Baseline up until documented progressive disease, death, lost to follow-up, or withdrawal by the participant, up to approximately 5 yearsSecondary outcomes
1
Duration of response (DOR) determined by investigators according to RECIST v1.1
DoR was defined as the period from the first occurrence of CR or PR to PD or death from any cause. If no PD or death after CR/PR, the cut-off date of progression-free survival (PFS) would be used \[Confirmed CR/PR assessment require at least one repeat (≥4 weeks)\].
Time frame
Baseline up until documented progressive disease, death, lost to follow-up, or withdrawal by the participant, up to approximately 5 years2
Disease control rate (DCR) determined by investigators according to RECIST v1.1
Objective tumor response for target lesions will be assessed by imaging/measurement compared with the overall tumor burden at baseline (Day -28 to -1). DCR was evaluated by the number of participants with best overall response of CR, PR and stable disease (SD) \[Confirmed CR/PR assessment require at least one repeat (≥4 weeks); SD shall be assessed at least 5 weeks after the first dose\].
Time frame
Baseline up until documented progressive disease, death, lost to follow-up, or withdrawal by the participant, up to approximately 5 years3
Overall survival (OS)
OS was defined as the time from random assignment or first dose to death from any cause.
Time frame
Baseline up until death up to approximately 5 years4
Incidence and severity of adverse events (AEs), serious adverse events (SAEs), AEs leading to treatment suspension, discontinuation
AE assessed by investigator exclusively related to subject's underlying disease or medical condition \[graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0\].
Time frame
Baseline up until documented progressive disease, death, lost to follow-up, or withdrawal by the participant, up to approximately 5 years.Sponsors and contacts
