Phase I Study of the Combination of Apatinib and POF
Study Details
Study Description
Brief Summary
In previous studies, we found that POF (A combination of oxaliplatin, fluorouracil and Paclitaxel) regimen appears to be of good efficacy and is well tolerated in patients with advanced gastric cancer. Apatinib is an orally antiangiogenic agent. It was approved and launched in China in 2014 as a 3rd-line treatment for patients with advanced gastric cancer. Therefore, investigators initialize this dose escalation phase I study to explore the safety of combination of apatinib and POF as first-line treatment for advanced gastric cancer. Investigators will analyze the maximum tolerated dose (MDT) and dose-limiting toxicity (DLT) of apatinib in this study.

Arms and Interventions

|---|---|
| Experimental: Apatinib plus POF This study will include a sequential evaluation of 3 subjects per cohort. Cohort 1: apatinib 250 mg per day and POF. Cohort 2: apatinib 375 mg per day and POF. Cohort 3: apatinib 500 mg per day and POF. Cohort 4: apatinib 625 mg per day and POF. Cohort 5: apatinib 750 mg per day and POF. A dose limiting toxicity (DLT) event is defined as any of the following events in the first 4-week period: CTCAE Grade 4 event (except for neutropenia lasting for ≤ 5 days); Grade 3 non-hematologic toxicity (except for nausea and vomiting that could be improved with optimal supportive care, escalation of alkaline phosphatase) If a DLT is experienced in any cohort, the cohort will be expanded to 6 subjects. If 2 DLTs are experienced in any cohort, the dose escalation ceased. The MTD was defined as the dose having at most two out of six patients experience DLT. |
Drug: Apatinib
Apatinib 250mg p.o. qd in first cohort (3 subjects). 375mg p.o. qd in second cohort (3 subjects). 500mg p.o. qd in third cohort (3 subjects). 625mg p.o. qd in forth cohort (3 subjects); 750mg p.o. qd in fifth cohort (3 subjects).

Drug: POF
The POF regimen consisted of a 3-hour infusion of paclitaxel (135 mg/m2) followed by oxaliplatin (85 mg/m2) and Calcium Levofolinate (200 mg/m2).Subsequently, a 46-hour infusion of fluorouracil (2400 mg/m2) was administered using an ambulatory pump, repeating the cycle every 14 days.

Outcome Measures
Primary Outcome Measures
- Dose limiting toxicity [From enrollment to completion of study. Estimated about 12 months.]
Dose limiting toxicity (DLT) is referred to grade 3 non-hematological toxicity or grade 4 hematological toxicity according to NCI CTCAE 4.03 criteria
- Maximum tolerance dose [From enrollment to completion of study. Estimated about 12 months.]
Maximum tolerance dose (MTD) is the dose of treatment in the cohort where there are 2 cases of DTL reported.
Secondary Outcome Measures
- Objective response rate [From enrollment to 3 months after treatment]
Clinical response of treatment according to RESIST v1.1 criteria (ORR, objective response rate).
- Progression-free survival [From enrollment to progression of disease. Estimated about 6 months.]
The length of time from enrollment until the time of progression of disease (PFS, progression-free survival).
- Overall survival [From enrollment to death of patients. Estimated about 1 year.]
The length of time from enrollment until the time of death (OS, overall survival).
