Efficacy and Safety of Toripalimab Combined With Docetaxel or Nab-paclitaxel in Patients With Advanced Gastric Cancer

Phase 2

• Conditions: Gastric Cancer Stage IV
• Interventions: Drug: Toripalimab; Drug: Docetaxel; Drug: nab-paclitaxel

• Registration Number: NCT04563975
• Lead Sponsor: Tao Zhang

Brief Summary

The single arm clinical study is to evaluate the efficacy and safety of an anti-PD-1 antibody (Toripalimab) combined with chemotherapy (docetaxel or nab-Paclitaxel) in patients with advanced gastric cancer who failed first-line treatment.

Detailed Description

54 patients who meet the inclusion criteria will receive Docetaxel (60-75mg/m2, every 3 weeks) or nab-Paclitaxel （125mg/m2，every 3 weeks）combined with Toripalimab( 240mg,every 3 weeks）for 4-8 cycles until the disease progresses or intolerable toxicity.
