Phase 3 |
Detailed Description
A multicenter, randomized, double-blind, positive drug parallel control design was used. The trial included screening period (4 weeks) and treatment period (4 treatment cycles, at least 12 weeks). All eligible subjects were randomly divided into experimental group (hs627 treatment group) and control group (pertuzumab) treatment group. After 4 treatment cycles, the subjects arranged surgical treatment, and then conducted the last visit.

Outcome Measures
Primary Outcome Measures
- Percentage of participants achieving Pathological Complete Response (pCR) as Assessed by the Independent Review Committee (IRC) [After surgery (At surgery cycle 4 Days 22-35)(1 cycle = 21 days)]
pCR was defined as ypT0/is According to the American Joint Committee on Cancer Staging System as Assessed by the IRC
Secondary Outcome Measures
- Percentage of Participants With Total Pathologic Complete Response (tpCR) as Assessed by the Independent Review Committee (IRC) [After surgery (At surgery cycle 4 Days 22-35) (1 cycle = 21 days)]
tpCR was defined as ypT0/is, ypN0 as assessed by an Independent Review Committee (IRC)
- Percentage of Participants With pCR as Assessed by the Local Pathologist [After surgery (At surgery cycle 4 Days 22-35) (1 cycle = 21 days)]
pCR was defined as ypT0/is as assessed by Local Pathologist
- Percentage of Participants With Total Pathologic Complete Response (tpCR) as Assessed by the Local Pathologist [After surgery (At surgery cycle 4 Days 22-35) (1 cycle = 21 days)]
tpCR was defined as ypT0/is, ypN0 as assessed by Local Pathologist
- Percentage of Participants With an Objective Response [Prior to surgery (Cycle 4 Days 21) (1 cycle = 21 days)]
An objective response was defined as the percentage of participants who achieved a complete response or partial response as the best tumor response during the treatment period (that is, during Cycles 1-4 prior to surgery), as determined by the investigator on the basis of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
- Percentage of Participants with vital signs, physical examination, left ventricular ejection fraction (LVEF), laboratory examination, adverse events (AE) until last visit [Last Visit (After surgery 8 days)(After 4 cycles treatment ,After surgery ) (1 cycle = 21 days)]
The percentage of participants who experienced at least one vital sign, physical examination, left ventricular ejection fraction (LVEF), laboratory examination, adverse events (AE) during the study is reported here.
