Study Details

Study Description

Brief Summary

This is an open label, multi-cohort, multicenter Phase II study, the purpose of this study is to assess the efficacy and safety of envofolimab in combination with BD0801 injection with/without chemotherapy for the treatment of advanced solid tumors

Condition or Disease	Intervention/Treatment	Phase
Advanced Solid Tumor	Drug: Envofolimab Drug: BD0801 Drug: Docetaxel Drug: Irinotecan Drug: Leucovorin calcium Drug: 5-Fluorouridine	Phase 2

Detailed Description

The efficacy of immune checkpoint inhibitors combined with antivascular agents has been preliminarily demonstrated in a variety of solid tumors. Based on the huge clinical needs, the efficacy of envofolimab combined with BD0801 in patients with advanced hepatocellular carcinoma, non-small cell lung cancer and advanced colorectal cancer deserves further exploration.

Secondary Outcome Measures

PFS was defined as the time from the date of randomization to the first documented disease progression or death, whichever occurred first. Progression was based on tumor assessment made by the investigator according to the RECIST1.1 criteria
DCR(Disease Control Rate) by investigator [1.5 years]
Proportion of subjects who have a complete or partial response, or stable disease relative to baseline as assessed by investigator according to RECIST 1.1 criteria
OS（Overall Survival) [2.5 years]
OS is the time interval from the date of randomization to death from any cause.
The incidence of AEs（adverse events) and SAEs（serious adverse events) [2 years]
Frequency and severity of Adverse Events or Serious Adverse Events as defined by CTCAE version 5.0
ORR in subgroup of different TMB、PDL-1 and MSI status [1.5 years]
Proportion of subjects who have a complete or partial response relative to baseline as assessed by investigator according to RECIST 1.1 criteria in subgroup of different TMB、PDL-1 and MSI status

Other Outcome Measures

PK(pharmacokinetics) of envofolimab and BD0801 [1.5 years]
Plasma concentrations of envofolimab an BD0801 will be measured.
Positive rate of ADA(anti-drug antibody) [1.5 years]
