About

The study is a multicenter, open-label, randomized controlled clinical study. The purpose of the study is to evaluate the efficacy and safety of apatinib combined with chemotherapy versus chemotherapy in second-line gastric cancer receiving prior anti-PD-1 therapy.

Full description

60 patients who meet the inclusion criteria will receive apatinib combine with chemotherapy or chemotherapy until the disease progresses or intolerable.

Apatinib: initial dose: 500mg,oral,once a day, after meal (try to take the medicine at the same time each day)

Enrollment: 60 estimated patients

Sex: All

Ages: 18+ years old

3. Failure or intolerance of first-line chemotherapy which requires that the first-line chemotherapy regimen include the scheme based on anti-PD-1 drugs for no less than 2 months (Definition of treatment failure: intolerence of toxic side effects; disease progression during treatment; Or recurrence after the end of treatment.) Note: (1)The treatment of each line advanced disease includes one or more drugs with a medication time ≥ 1 cycle. (2) Early adjuvant/neo-adjuvant therapy is allowed. If recurrence occurs during adjuvant/neoadjuvant therapy or within ≤24 weeks after completion, adjuvant/neoadjuvant therapy is considered to be a first-line pre-systemic chemotherapy for advanced disease. (3) Early-stage immunotherapy, combined chemotherapy or combined targeted drugs are allowed (except for VEGFR inhibitors).
4. Patients must have at least 1 lesion that is measurable using RECIST v1.1 criteria
5. ECOG performance status 0-1.
6. An expected survival of > 12 weeks.
7. Has adequate sufficient organ and bone marrow functions.
8. Patients whose adverse events caused by previous treatment have recovered to <= CTCAE 1 degree; And the interval between receiving nitroso or mitomycin ≥6 weeks; Receiving other cytotoxic drugs, radiotherapy or surgery ≥ 4 weeks, and the wound has healed completely.
9. Fertile female subjects must undergo a serum-negative pregnancy test within 72 hours before starting the study drug
10. Patients have agreed and signed the informed consent. Willingness and able to follow the planned visit, research treatment, laboratory examination and other test procedures.
