NCT04498793

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of tislelizumab plus chemotherapy vs chemotherapy alone as perioperative treatment in participants who have triple negative HER2 negative breast cancer. After a screening phase of approximately 28 days, each participant will receive neoadjuvant study treatment (Tislelizumab + Chemotherapy OR Chemotherapy) based on the randomization schedule for approximately 24 weeks (8 cycles). Each participant will then undergo definitive surgery 3-6 weeks after conclusion of the last cycle of the neoadjuvant study treatment. After definitive surgery, each participant will receive adjuvant study treatment (routine adjuvant treatment +/- Tislelizumab) for approximately 42 weeks (14 cycles). Following adjuvant study treatment, each participant will be monitored for safety, survival and disease recurrence.

Outcome Measures

Primary Outcomes (1)

  • Pathological complete response (pCR) rate using the definition of ypT0/Tis ypN0 (i.e., no invasive residual in breast or nodes; noninvasive breast residuals allowed) at the time of definitive surgery

    pCR rate (ypT0/Tis ypN0) is defined as the percentage of participants without residual invasive cancer on hematoxylin and eosin evaluation of the complete resected breast specimen and all sampled regional lymph nodes following completion of neoadjuvant systemic therapy by current American Joint Committee on Cancer (AJCC) staging criteria assessed by the local pathologist at the time of definitive surgery.

    Up to 30 weeks

Study Arms (2)

PD-1 group

EXPERIMENTAL

Participants receive tislelizumab every 3 weeks (Q3W) + nab-paclitaxel weekly x 4 cycles, followed by tislelizumab Q3W + (doxorubicin OR epirubicin) + cyclophosphamide Q3W x 4 cycles as neoadjuvant therapy prior to surgery; followed by 14 cycles of tislelizumab Q3W plus capecitabine (TNBC subtype) or endocrine therapy (Luminal subtype) as adjuvant therapy post-surgery. Each cycle is 21 days.

Control group

ACTIVE COMPARATOR

Participants receive nab-paclitaxel weekly x 4 cycles followed by (doxorubicin OR epirubicin) + cyclophosphamide Q3W x 4 cycles as neoadjuvant therapy prior to surgery; followed by capecitabine (TNBC subtype) or endocrine therapy (Luminal subtype) as adjuvant therapy post-surgery. Each cycle is 21 days.
