A Phase II Study to Explore the Safety, Tolerability, and Preliminary Antitumor Activity of Sitravatinib Plus Tislelizumab or Combination With Nab-paclitaxel in Patients With Locally Recurrent or Metastatic Triple Negative Breast Cancer (TNBC) (SPARK)

The purpose of this study is to assess the efficacy and safety of sitravatinib plus tislelizumab or combination with nab-paclitaxel in locally recurrent or metastatic triple-negative breast cancer (TNBC) patients.

Study Overview

• Status: Active, not recruiting
• Conditions: Metastatic Breast Cancer
• Intervention / Treatment: Drug: Sitravatinib; Drug: Tislelizumab; Drug: Nab-paclitaxel

Detailed Description

This is a prospective, single-center, three cohorts, phase II clinical trial in locally recurrent or metastatic triple-negative breast cancer(TNBC) patients. Subjects will be divided into three cohorts by different treatment combination. Cohort A & Cohort B aim to explore the two dosages of sitravatinib in combination with tislelizumab in TNBC with prior ≤ 3 treatment line. Cohort A patients will receive 70mg sitravatinib (QD PO) in combination with 200mg tislelizumab (Q3W IV); Cohort B patients will receive 100mg sitravatinib (QD PO) in combination with 200mg tislelizumab (Q3W IV). Cohort C aims to explore the sitravatinib (QD PO) plus 200mg tislelizumab (Q3W IV) and 100 mg/m2 nab-paclitaxel (D1, D8 Q3W IV) in TNBC previously untreated for metastatic setting or recurred/metastasized after surgery. Subjects in the three cohorts will be treated until disease progression, intolerable toxicity, informed consent withdrawn, or investigators-determined medication termination. Drug efficacy and safety data will be collected.
