Detailed Description

This study is a single-arm, multi-center, two-stage, phase II clinical trial conducted in China. This study adopts Simon's two-stage design, and the inclusion criteria and exclusion criteria of the two stages were consistent. Twelve patients with extrapulmonary neuroendocrine carcinoma will be enrolled in the first stage. If more than four complete or partial responses were seen at planned interim analysis, the additional 16 patients will be recruited in the second stage and a total of 28 patients will be treated.

Interventions

  • Drug: Chidamide
    • 20mg, administered orally. Week 1/2: twice a week (d0, d4, d7, d11); Week 3: stop. Repeat every 3 weeks for 4-6 cycles.
  • Drug: Etoposide + Cisplatin/Carboplatin
    • Etoposide (100mg/m2; intravenous infusion; d1-3) + Cisplatin (75mg/m2; intravenous infusion; d1). Repeat every 3 weeks for 4-6 cycles. OR Etoposide (100mg/m2; intravenous infusion; d1-3) + Cisplatin (25mg/m2; intravenous infusion; d1-3). Repeat every 3 weeks for 4-6 cycles. OR Etoposide (100mg/m2; intravenous infusion; d1-3) + Carboplatin (AUC=5; intravenous infusion; d1). Repeat every 3 weeks for 4-6 cycles.

Arms, Groups and Cohorts

  • Experimental: Chidamide + Etoposide + Cisplatin/Carboplatin
    • Experimental arm will be treated by chidamide combined with etoposide and cisplatin/carboplatin regimen for 4-6 cycles.

Clinical Trial Outcome Measures

Primary Measures

  • Objective Response Rate (ORR)
    • Time Frame: Up to 2 years
    • Percentage of participants with complete response and partial response, assessed by the investigators according to the Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1

Secondary Measures

  • Disease Control Rate (DCR)
    • Time Frame: Up to 2 years
    • Percentage of participants with complete response, partial response, and stable disease assessed by the investigators according to the Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1
  • Progression-free Survival (PFS)
    • Time Frame: Time from the date of enrollment to the earliest of documented disease progression or death, assessed up to 2 years
    • Time from the date of enrollment until progression or death, whichever is first met
  • Overall Survival (OS)
    • Time Frame: Time from the date of enrollment to the earliest of documented death, assessed up to 3 years
    • Time from the date of enrollment until death
  • Treatment-related Adverse Events (Safety)
    • Time Frame: Up to 2 years
    • Frequency and grade of adverse events (the grade of adverse events is assessed according to CTCAE v4.03).
