A Study to Evaluate Safety, Tolerability, PK/PD and Preliminary Efficacy of HBM4003 Combine With Toripalimab in Patients With Advanced HCC and Other Solid Tumors

Phase 1
Conditions
Solid Tumors
Interventions
Drug: HBM4003 and Triprilimab
Registration Number
NCT05149027
Lead Sponsor
Harbour BioMed (Guangzhou) Co. Ltd.
Brief Summary

This is an open-label, multi-center phase 1 study. The trial, consisting of Part

1 dose confirmation and Part 2 dose expansion, is designed to evaluate the safety, tolerability, PK/PD and preliminary efficacy of HBM4003 in combination with Toripalimab in patients with advanced HCC and other solid tumors.

Detailed Description

subjects will be treated with HBM4003 in combination with Toripalimab for up to 2 years or until confirmed disease progression, unacceptable tolerability or treatment discontinuation through withdrawal of consent occurs, whichever happens first.

This trial consists of :

* A screening period: 28 days

* A treatment period:

* Part 1 dose confirmation study

* Part 2 dose expansion study

* A post-treatment follow-up period, including

* A safety follow-up period: 28 days after the last dose of study drug;

* Post-treatment follow-up visit: day 84 after the last dose of study drug;

* Survival follow-up.

Primary Outcome Measures
NameTimeMethod
Part1:Number of subjects with DLT in each dose group within 1 cycles (21 days) after the first drug administrationapproximate 21 days

Number of subjects who experience DLT events

Part1:The maximum tolerated dose (MTD) of HBM4003 combined with toripalimabapproximate 21 days
Part1:Recommended Phase 2 dose (RP2D) of HBM4003 combined with toripalimabapproximate 21 days
Part2:ORR, as determined by the Investigator using RECIST 1.1maximum 2 years

Proportion of subjects with complete response (CR) and partial response (PR)

Secondary Outcome Measures
NameTimeMethod
Part 1: Duration of Disease Control, DDC, as determined by the Investigator using RECIST 1.1 for solid tumors, using RECIST 1.1 and mRECIST for HCCmaximum 2 years

For subjects with Cr, PR or SD, the duration from the time of initial administration to the date of disease progression or death (for any reason) was calculated

Part2: Duration of Response, DOR, as determined by the Investigator using RECIST 1.1 and mRECIST for HCCmaximum 2 years

Calculate the duration from the first confirmed CR or PR to the date of disease progression or death (for any reason)

Part 2: Progression-free survival (PFS)maximum 2 years

the length of time from the beginning of treatment to the beginning of disease progression or death (for any reason)

Part 1:ORR, as determined by the Investigator using RECIST 1.1 for solid tumors, using RECIST 1.1 and mRECIST for HCCmaximum 2 years]

Proportion of patients with complete response (CR) and partial response (PR)

Part 1: Disease Control Rate, DCR, as determined by the Investigator using RECIST 1.1 for solid tumors, using RECIST 1.1 and mRECIST for HCCmaximum 2 years

including proportion of subjects with complete response (CR) and partial response (PR) and stable disease (SD)

Tmaxmaximum 2 years

Time to reach maximum serum concentration

AUC0-taumaximum 2 years

Area under the serum concentration versus time curve from time zero to the dosing interval tau

Part 2: Overall survival (OS)maximum 2 years

the length of time from the start of treatment to the death of the subject (for any reason)

Part 1: Duration of Response, DOR, as determined by the Investigator using RECIST 1.1 for solid tumors, using RECIST 1.1 and mRECIST for HCCmaximum 2 years

Calculate the duration from the first confirmed CR or PR to the date of disease progression or death (for any reason)

Part2: ORR, as determined by the Investigator using mRECIST for HCCmaximum 2 years

Proportion of patients with complete response (CR) and partial response (PR)

Part 2: Disease Control Rate, DCR, as determined by the Investigator using RECIST 1.1 and mRECIST for HCCmaximum 2 years

including proportion of subjects with complete response (CR) and partial response (PR) and stable disease (SD)

Cmaxmaximum 2 years

Peak Plasma Concentration

AUC0-lastmaximum 2 years

Area under the plasma concentration versus time curve from time zero to last

Part2:Duration of Disease Control, DDC, as determined by the Investigator using RECIST 1.1 and mRECIST for HCCmaximum 2 years

For subjects with Cr, PR or SD, the duration from the time of initial administration to the date of disease progression or death (for any reason) was calculated

The immunogenicity of HBM4003 and Triprilimabmaximum 2 years

Including the incidence of ADA positive. For ADA positive patients, the incidence of neutralizing antibody (NAB) was analyzed.
