- Registration Number
- NCT04629846
- Lead Sponsor
- Qilu Pharmaceutical Co., Ltd.
- Brief Summary
This is a randomized, double-blind, multicenter trial，parallel control designed to evaluate treatment with trastuzumab + QL1209 + docetaxel compared with trastuzumab + pertuzumab + docetaxel in the participants with early-stage or locally advanced HER2-positive and estrogen receptor/progesterone receptor negative breast cancer. The anticipated treatment duration is approximately 140 days.
- Detailed Description
This is A multi-center, randomized, double-blind, parallel control，comparative clinical trial.
The primary objective is to evaluate whether the clinical efficacy of QL1209 and pertuzumab are similar in patients with early-stage or locally advanced HER2-positive and estrogen receptor/progesterone receptor negative breast cancer.
The secondary objective are to evaluate whether the clinical safety and immunogenicity of QL1209 and pertuzumab are similar in patients with early-stage or locally advanced HER2-positive and estrogen receptor/progesterone receptor negative breast cancer.

- Primary Outcome Measures
Name Time Method Total pathologic complete response (tpCR) rate Approximately 26 months after randomization of the first patient, when all patients have completed the treatment completion/discontinuation visit Total pathologic complete response (tpCR) rate, defined as ypT0/is, ypN0 as assessed by an Independent Review Committee (IRC)
- Secondary Outcome Measures
Name Time Method Percentage of Participants With Breast Pathologic Complete Response (bpCR) assessed by the IRC Approximately 26 months after randomization of the first patient, when all patients have completed the treatment completion/discontinuation visit This bpCR was assessed by the IRC. bpCR is defined as the absence of any residual invasive cancer on the hematoxylin and eosin evaluation of the resected breast specimen after completion of neoadjuvant therapy and surgery (that is, ypT0/is, in accordance with current AJCC staging system).
Percentage of Participants With bpCR as Assessed by the Local Pathologist At surgery This bpCR was assessed by the local pathologist. bpCR is defined as the absence of any residual invasive cancer on the hematoxylin and eosin evaluation of the resected breast specimen after completion of neoadjuvant therapy and surgery (that is, ypT0/is in accordance with current AJCC staging system).
Percentage of Participants With an Objective Response Before surgery 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 neoadjuvant 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. No confirmation was required for objective response. Only participants with measurable disease at baseline were included in the analysis. The duration of one treatment cycle is 21 days; the administration of therapy in Cycle 5 should not occur until 2 weeks after surgery.
Percentage of Participants With tpCR as Assessed by the Local Pathologist At surgery This tpCR was assessed by the local pathologist. tpCR is defined as the absence of any residual invasive cancer on hematoxylin and eosin evaluation of the resected breast specimen and all sampled ipsilateral lymph nodes after completion of neoadjuvant therapy and surgery (that is, ypT0/is, ypN0, in accordance with the current American Joint Committee on Cancer \[AJCC\] staging system).
