Official title

JS207 Combination Therapy in Recurrent or Metastatic Triple-negative Breast Cancer(TNBC)

Overview

This is an open-label, multi-center, phase II clinical study to preliminarily evaluate the efficacy and safety of JS207 combined with 9MW2821 or albumin paclitaxel as first-line therapy in patients with recurrent or metastatic TNBC.

Detailed description

The study consists of Cohort A and Cohort B. Both cohorts include patients with recurrent or metastatic TNBC who have not received systemic anti-tumor therapy previously. Cohort A will receive JS207 combined with 9MW2821, and Cohort B will receive JS207 combined with albumin paclitaxel. Each cohort consists of two stages: safety run-in period and cohort expansion period.

Interventions

  • Drug JS207 in combination with 9MW2821
    JS207 will be administered intravenously at a dose of 10 mg/kg (D1, Q3W), 9MW2821 will be administered intravenously at a dose of 1.25 m.g/kg (D1 and D8, Q3W)
  • Drug JS207 in combination with Albumin paclitaxel
    JS207 will be administered intravenously at a dose of 10 mg/kg (D1, Q3W), Albumin paclitaxel will be administered intravenously at a dose of 125 mg/m2 (D1 and D8, Q3W).
