Study of S-1 Plus LV for Advanced Gastric Cancer

Phase 2
Completed
Conditions
Gastric Cancer
Interventions
Registration Number
NCT02090153
Lead Sponsor
Sun Yat-sen University
Brief Summary

The purpose of this study is to evaluate the effectiveness and safety of S-1 plus Leucovorin (1 week on and 1 week off) as first-line treatment for patients with metastatic and recurrent gastric cancer.

Detailed Description

Patients enrolled in this study were orally treated with S-1 in doses of 40 mg (body surface area (BSA)\<1.25 m2), 50 mg (1.25≤BSA\<1.50 m2) and 60 mg (BSA≥1.50 m2) b.i.d. on days 1-7 in combination with LV given simultaneously at a fixed dose of 25 mg b.i.d. on days 1-7, followed by a 7 day rest. Treatment courses were repeated every 2 weeks. Treatment was continued until progressive disease (PD), unacceptable toxicity or patient refusal.

Primary Outcome Measures
NameTimeMethod
Overall Response Rate (ORR)1 year

The primary endpoint is overall response rate,which equals the rate of patients with CR+PR.

Secondary Outcome Measures
NameTimeMethod
Progression free survival (PFS)1-1.5 years

Progression-free survival (PFS) was determined from the date of treatment to progression or death

Overall survival (OS)1-2.5 years

Overall survival (OS) was calculated from the date of treatment to death from any cause or the last date of follow-up.

Time to treatment failure (TTF)1 year

Time to treatment failure (TTF) was determined from the date of treatment to progression, death, refusal or interruption due to adverse events.

Disease control rate1 year

Disease control rate equals the rate of patients with CR+PR+SD.

Adverse Events (AEs)2 year

All treatment-related adverse events (AEs) were categorized according to the National Cancer Institute's Common Terminology Criteria for Adverse Events.
