Phase 2 Study of TQB2102 Injection Combined With Bemarituzumab or Penpulimab With or Without Chemotherapy for Adults Aged 18 to 75 With Untreatable, Advanced, or Returning HER2-Positive Gastroesophageal Adenocarcinoma

What this Trial Is About

Researchers are evaluating TQB2102 for injection, a new antibody-coupled drug that targets two different parts of the HER2 protein on tumor cells. This study focuses on patients with unresectable locally advanced, recurrent, or metastatic HER2-positive gastroesophageal adenocarcinoma. The trial aims to assess the effectiveness and safety of TQB2102 combined with benmelstobart or penpulimab, with or without chemotherapy, in this patient group. This is a Phase II randomized study sponsored by Chia Tai Tianqing Pharmaceutical Group Nanjing Shunxin Pharmaceutical Co., Ltd. Participants receive TQB2102 for injection and either benmelstobart or penpulimab, both given intravenously every three weeks. Chemotherapy is taken orally from Day 1 to Day 15 in each 21-day treatment cycle. There are three study groups, each involving different combinations and doses of TQB2102, benmelstobart, penpulimab, and chemotherapy. Treatment continues through multiple cycles as determined by the study protocol. During the study, participants undergo regular assessments including scans and tests to measure tumor response and disease progression. Researchers monitor outcomes like the objective response rate, progression-free survival, duration of response, overall survival, and any adverse events. The study includes follow-up periods to track safety and effectiveness, with an average observation of up to three years. Participants are closely monitored throughout the treatment and follow-up phases for their health and response to therapy.
