Telatinib in Combination With Capecitabine/ Oxaliplatin in 1st Line Gastric or GEJ Cancer

Phase 2

• Conditions: Gastric Cancer
• Interventions: Drug: Telatinib; Drug: Capecitabine; Drug: Oxaliplatin; Drug: Placebos

• Registration Number: NCT03817411
• Lead Sponsor: Taizhou EOC Pharma Co., Ltd.

Brief Summary

The purpose of the trial is to compare the combination regimen of Telatinib and Capecitabine and Oxaliplatin vs. Capecitabine and Oxaplatin to explore superiority of the Telatinib combination in terms of progression-free survival (PFS) in patients previously untreated for advanced HER2 negative advanced gastric or Gastroesophageal Junction adenocarcinoma.

Detailed Description

This trial is a Phase 2, prospective, double-blind, randomized, comparative, multicenter trial in patients with advanced HER2 negative adenocarcinoma of the stomach or Gastroesophageal Junction which has progressed after resection and adjuvant or neoadjuvant therapy, or is unresectable or metastatic at time of first diagnosis. a total of approximately 90 patients will be enrolled and randomized into Telatinib combined with Capecitabine and Oxaliplatin or chemotherapy combined with placebo. All patients will be treated until progressive disease (radiologically documented or symptomatic deterioration) or the occurrence of unacceptable toxicity, withdrawal of consent or investigator's judgment.

Exclusion Criteria

2. Active and uncontrolled central nervous system (CNS) metastases .
3. During the screening and study period, standard dose of anticoagulant or thrombolytic drugs are used for treatment;
4. History of any second malignancy in the last 5 years; patients with prior history of in-situ cancer or basal or squamous cell skin cancer are eligible. Patients with other malignancies are eligible if they have been continuously disease free for at least 5 years.
5. Evidence of tumor invasion of major blood vessels by images(including complete proximity, surrounding or extending into the main vascular lumen, such as the pulmonary artery or the superior vena cava), and the investigator judged that it was not suitable for enrollment.
6.
