Clinical Trial of TQB2102 for Injection Versus Trastuzumab Emtansine for Injection in HER2-positive Advanced Breast Cancer

Официальное название

A Randomized, Open-label, Parallel-controlled Phase III Clinical Trial to Evaluate the Efficacy and Safety of TQB2102 for Injection Versus Trastuzumab Emtansine for Injection in Patients With HER2-positive Advanced Breast Cancer

Обзор

This study adopted a randomized, open-label, positive drug-controlled, multi-center trial design. The primary endpoint was PFS evaluated by the Independent Review Committee (IRC). Eligible subjects were randomly assigned in a 1:1 ratio to receive either TQB2102 for injection or trastuzumab emtansine for injection.

Вмешательства

• Препарат TQB2102 Injection
  TQB2102 Injection is a Human Epidermal Growth Factor Receptor 2 (HER2) bispecific antibody-drug conjugate.
• Препарат Trastuzumab Emtansine for Injection
  Trastuzumab Emtansine for Injection is HER2-targeting antibody-drug conjugate (ADC).
