Nab-P+Cb+PD1 Inhibitors as Neoadjuvant Therapy for Early TNBC

Официальное название

Nab-P+Cb+PD1 Inhibitor Neoadjuvant Therapy for Early TNBC: a Single Center, Non Blinded, Randomized Phase II Clinical Trial

Обзор

We plan to explore the efficacy and safety of albumin-bound paclitaxel+carboplatin+Camrelizumab in neoadjuvant therapy for early TNBC patients, optimize the administration method and drug combination therapy.

Подробное описание

This study is a single center, non blinded, randomized phase II clinical trial. A total of 64 TNBC patients are planned to be enrolled. Patients who meet the inclusion criteria will be randomly divided into two groups (Group A and Group B) at a ratio of 1:1, and stratified according to T stage and N stage. The administration regimen is as follows: Group A： albumin-bound paclitaxe (260 mg/m²,d 1)+Carboplatin (AUC=5, d 1)+Camrelizumab (200 mg, d 1), 21 days as one cycle, 6 cycles; Group B: albumin-bound paclitaxe (125 mg/m²,d 1,8,15)+Carboplatin (AUC=5, d 1 )+Camrelizumab (200 mg, d 1), 21 days as one cycle, 6 cycles

Primary endpoint: Pathological complete response rate (pCR rate).

Secondary study endpoints: Objective response rate (ORR), event free survival rate (EFS), disease-free survival (DFS), distant disease free survival (DDFS), and safety.

Exploratory endpoints: Differences in efficacy and immune microenvironment under different administration methods
