About this trial
This multicenter, randomized, double-blind study aims to assess the safety and efficacy of AK112 in combination with Nab-Paclitaxel, compared to a placebo plus Nab-Paclitaxel, as a first-line treatment for inoperable locally advanced or metastatic triple-negative breast cancer (TNBC).

Trial outcomes
Primary outcomes
PFS assessed by IRRC
Progression-Free Survival (PFS) assessed by Independent Radiologic Review Committee (IRRC)
OS
Overall survival (OS) is defined as the time from randomization to death due to any cause
Secondary outcomes
PFS assessed by investigator
Progression-free survival is defined as the time from randomization to the first documented PD per RECIST 1.1 based on assessments by investigator or death due to any cause, whichever occurs first.
ORR assessed by IRRC or investigators
Objective Response Rate (ORR) is defined as the percentage of participants in the analysis population who have a complete response (CR: disappearance of all lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions). The percentage of participants who experienced a CR or PR as assessed by IRRC or investigators based on RECIST 1.1 is presented.
DCR assessed by IRRC or investigators
Disease control rate (DCR) is defined as the sum rate of CR, PR and Stable Disease (SD), as determined by IRRC or investigators using RECIST v1.1
DoR assessed by IRRC or investigators
Duration of response (DoR) is defined as the time period from the date of initial CR or PR until the date of PD or death due to any cause, whichever occurs first.
