Cyclophosphamide

Phase

PHASE2

Detailed Description:

Primary Objective To estimate the rate of pCR in patients with cT1b and T1cN0M0 TNBC after neoadjuvant therapy with 4 cycles of Pembrolizumab + Carboplatin + Paclitaxel. Secondary Objective To assess the safety and toxicity profile of pembrolizumab plus chemotherapy in participants receiving an anthracycline-de-escalated regimen of carboplatin, paclitaxel and pembrolizumab by recording the incidence of treatment emergent adverse events. Exploratory Objectives 1. To estimate the invasive disease-free survival (iDFS), and overall survival (OS) in participants with cT1b-T1cN0 TNBC that receive neoadjuvant pembrolizumab plus chemotherapy in the setting of an anthracycline de-escalation study. 2. To explore if there is a molecular signature associated with response or lack of response to therapy. 3. To evaluate patient reported outcomes of participants receiving this de-escalated regimen.
