Brief Title  ICMJE BGB A317 in Combination With Chemotherapy as First-Line Treatment in Adults With Inoperable, Locally Advanced or Metastatic Esophageal, Gastric, or Gastroesophageal Junction Carcinoma
Official Title  ICMJE A Phase 2, Multi-Cohort Study to Investigate the Safety, Pharmacokinetics and Preliminary Antitumor Activity of the Anti-PD-1 Monoclonal Antibody BGB A317 in Combination With Chemotherapy as First-Line Treatment in Adults With Inoperable, Locally Advanced or Metastatic Esophageal, Gastric, or Gastroesophageal Junction Carcinoma
Brief Summary This is a Phase 2, multi-cohort study to investigate safety, PK, and preliminary anti-tumor activity of the monoclonal antibody BGB A317 in combination with standard chemotherapy as first-line treatment. Cohorts include an ESCC cohort and a gastric carcinoma (GC) or GEJ carcinoma cohort that will be enrolled concurrently. The study includes a screening (up to 28 days), treatment (until disease progression, intolerable toxicity, or treatment withdrawal for another reason), safety follow-up (up to 30 days following last study drug treatment), and survival follow-up phase.
Detailed Description

The study includes an initial phase during which 6 subjects will be enrolled in each cohort (ESCC and GC/GEJ carcinoma). Safety data will be reviewed by a Safety Monitoring Committee (SMC) after the first 6 subjects in a cohort have completed at least 1 cycle (21 days) of treatment. During the initial phase, subjects who discontinue for a reason unrelated to safety before completing Cycle 1 will be replaced. If there are no new, significant or severe, safety signals detected, the enrollment will be expanded up to approximately 15 subjects per cohort (treatment expansion). During the treatment expansion, subjects will not be replaced for any reason.

In the ESCC cohort, subjects will be treated with BGB A317 200 mg IV on Day 1, cisplatin 80 mg/m² IV on Day 1, and 5-FU 800 mg/m²/day IV using continuous pumping system on Days 1 through 5 during each 21-day cycle. Cisplatin and 5-FU will be given for up to 6 cycles and BGB A317 will be administered until disease progression, intolerable toxicity, or treatment discontinuation for any other reason.

In the GC and GEJ carcinoma cohort, subjects will be treated with BGB A317 200 mg IV on Day 1, oxaliplatin 130 mg/m² IV on Day 1, and capecitabine 1000 mg/m² orally twice daily (bid) Days 1 through 14 (14 days total) during each 21-day cycle. Oxaliplatin will be administered for up to 6 cycles and capecitabine and BGB A317 will be administered until disease progression, intolerable toxicity, or treatment discontinuation for any other reason.

Eligibility Criteria  ICMJE

Key Inclusion Criteria:

  1. Pathologically (histologically or cytologically) confirmed diagnosis of either inoperable, locally advanced or metastatic gastric/GEJ adenocarcinoma that is HER2/neu negative or inoperable, locally advanced or metastatic ESCC.

    Note: Archival tumor tissue (paraffin blocks or at least 10 unstained tumor specimen slides) must be available for biomarker analysis. In the absence of archival tumor tissues, a fresh biopsy of a tumor lesion at baseline is mandatory. Subjects may be permitted to enroll on a case-by-case basis after discussion with the Sponsor's medical monitors if paraffin block is not available and fewer than 10 unstained slides can be provided.

  2. Have received no prior systemic therapy for advanced or metastatic disease. Subject may have received prior neoadjuvant or adjuvant therapy provided it was completed at least 6 months prior to enrollment.
  3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 (Protocol Appendix 3).
  4. Life expectancy of at least 12 weeks.
  5. Adequate organ function as indicated by the following screening laboratory values:

Absolute neutrophil count (ANC) ≥1.5×109/L Platelet count ≥100×109/L Hemoglobin ≥9 g/dL or ≥5.6 mmol/L (Note: Criteria must be met without a transfusion within 4 weeks before sample is drawn).

Serum creatinine ≤1.5× upper limit of normal (ULN). Serum total bilirubin ≤1.5×ULN. For subjects with Gilbert's syndrome, total bilirubin must be <3×ULN) Prothrombin time/international normalized ratio (PT/INR) ≤1.5×ULN and activated partial thromboplastin time (aPTT) ≤1.5×ULN unless subject is receiving anticoagulant therapy and PT values is within the intended therapeutic range of the anticoagulant.
