Perioperative Chemotherapy With Low-Dose Radiotherapy and Tislelizumab for Locally Advanced Gastric or Gastroesophageal Junction Adenocarcinoma

This study is a prospective, multicenter, randomized, phase II clinical trial enrolling patients with resectable locally advanced gastric or gastroesophageal junction adenocarcinoma. The study aims to compare the efficacy and safety of perioperative chemotherapy combined with low-dose radiotherapy and tislelizumab versus perioperative chemotherapy alone in this patient population.

First-line Treatment of Gastric or Gastroesophageal Junction Adenocarcinoma With Dual Immunotherapy Combined With Chemotherapy

A prospective, single-arm, multicenter, Phase II clinical study of Apatolimab Tovolimab (QL1706) in combination with modified FLOT regimen (TFOX) as first-line treatment for HER2-negative advanced gastric or gastroesophageal junction adenocarcinoma

Utidelone Capsule Combined With Fluoropyrimidine- and Platinum-containing Therapy in First-line Treatment of Patients With Gastric or Gastroesophageal Junction Adenocarcinoma

This is a multi-national, open-label, randomized, seamless phase II/III clinical study of UTD2 combined with fluoropyrimidine- and platinum-containing therapy to evaluate the efficacy and safety in patients with locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma untreated with systemic treatment in advanced setting.

Phase II, Open-label, Multicenter Study to Evaluate the Efficacy and Safety of HLX43 (an Anti-PD-L1 ADC) in Subjects With Advanced Gastric or Gastroesophageal Junction Adenocarcinoma

The study is being conducted to to explore the reasonable dosage and evaluate the efficacy, safety and tolerability of HLX43 (Anti-PD-L1 ADC) in Patients with Advanced Gastric or Gastroesophageal Junction Adenocarcinoma

Spevatamig (PT886) as Monotherapy or in Combination With Chemo and/or ICI, for the Treatment of Patients With Advanced Gastric, Gastroesophageal Junction, Pancreatic Ductal or Biliary Tract Carcinomas (the TWINPEAK Study)

This is a first-in-human, Phase 1/2, open-label, dose escalation and dose expansion and combination study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of Spevatamig (PT886). Patients with the following tumor types will be eligible for screening: unresectable or metastatic gastric adenocarcinoma, gastroesophageal junction (GEJ) adenocarcinoma, biliary tract carcinoma (BTC) and pancreatic ductal adenocarcinoma (PDAC).

Immunotherapy Combined With Anti-angiogenic Therapy and Chemotherapy for Potentially Resectable MSI-H, dMMR Locally Advanced Gastric or Gastroesophageal Junction Adenocarcinoma

Efficacy and safety of Iparomlimab and Tuvonralimab in combination with lenvatinib and SOX chemotherapy in potentially resectable MSI-H, dMMR locally advanced gastric or gastroesophageal junction adenocarcinoma patients: A prospective, multicenter, open-label Phase II single-arm clinical trial

Efficacy and Safety of AK112 Combined Chemotherapy as Neoadjuvant Treatment for Signet Ring Cell-containing G/GEJ Adenocarcinoma

Study Overview The primary objective of this clinical trial is to evaluate the efficacy and safety of AK112 in combination with chemotherapy as a neoadjuvant treatment for patients with locally advanced, resectable gastric or gastroesophageal junction (G/GEJ) adenocarcinoma containing signet ring cells. Key Research Questions 1. Does neoadjuvant treatment with AK112 plus chemotherapy improve the pathological complete response (pCR) rate compared to chemotherapy alone in patients with locally advanced G/GEJ adenocarcinoma with signet ring cells? 2. What are the safety profile and additional efficacy outcomes of AK112 combined with chemotherapy in this patient population? To answer these questions, the study will compare the combination of AK112 and chemotherapy with chemotherapy alone. Participant Procedures Eligible participants will: 1. Receive standard-dose AK112 in combination with chemotherapy every 3 weeks for a total of 4 cycles prior to surgery. 2. Undergo preoperative CT or MRI imaging within 3-4 weeks after the last treatment cycle to assess tumor response and evaluate eligibility for curative resection. 3. If no evidence of disease progression is observed and surgical evaluation is favorable, patients will undergo curative-intent gastrectomy within 6 weeks of completing neoadjuvant therapy (including oral agents, if any). 4. Postoperatively, adjuvant therapy will be administered at the investigator's discretion. Patients will be followed until disease recurrence or metastasis. 5. Attend clinic visits every 6 weeks during the neoadjuvant phase for evaluations and laboratory tests. 6. Maintain a symptom diary throughout the study period. 7. Undergo follow-up assessments every 3 months, starting from the first dose of study medication until 30 days after the last dose or the initiation of a new anti-tumor therapy. Optional Imaging Substudy FAPI-PET/CT imaging will be explored as an optional diagnostic modality. Participation in this substudy will require separate informed consent and will be conducted under a future protocol amendment (pending IRB approval).

Neoadjuvant Chemo-hypoRT Plus PD-1 Antibody (Tislelizumab) in Resectable LA-G/GEJ

Gastric cancer is the third leading cause of death due to cancer worldwide. Although the consensus on the surgical treatment has resulted in the improvement of curative effect during the past decades, controversies remained for the perioperative therapy of gastric cancer, especially in the selection of the optimal neoadjuvant regimens. Immunotherapy with anti-programmed cell death-1 (PD-1) antibody has demonstrated moderate efficacy in selected patients with advanced gastric adenocarcinoma. Hypofractionated radiotherapy (HypoRT) may act synergistically with immunotherapy to enhance antitumor responses. This phase II trial study want to exploit the efficacy and safety to give PD-1 antibody (Tislelizumab) with combination chemotherapy and HypoRT before surgery in treating adult patients with gastric or gastroesophageal junction adenocarcinoma.
