Brief Summary

This is an open label, randomized, phase Ⅱ, multi-cohort study to treat subjects with ctDNA Positive Gastric and Esophagogastric Junction Adenocarcinoma. The patients will be randomized into two arms consist of Penpulimab + Anlotinib (3 weeks/cycle) + XELOX and XELOX at a ratio of 1:1.

Detailed Description

This is an open label, randomized, phase Ⅱ, multi-cohort study to treat subjects with ctDNA Positive Gastric and Esophagogastric Junction Adenocarcinoma. The patients will be randomized into two arms consist of Penpulimab + Anlotinib (3 weeks/cycle) + XELOX and XELOX at a ratio of 1:1. This study is conducted to assess safety and anti-tumor activity of the monoclonal antibody Penpulimab in combination with Anlotinib and standard chemotherapy as adjuvant treatment for ctDNA-positive Gastric, or Gastroesophageal Junction Carcinoma. The study includes a screening (up to 28 days), treatment (disease recurrence, unacceptable toxicity, or subject withdrawal of consent with a maximum 12 month), safety follow-up (up to 30 days following last study drug treatment), and survival follow-up phase.
