Brief Summary

The INTEGA study assesses therapy Options for advanced or metastatic esophagogastric Adenocarcinoma in patients overexpressing human epidermal receptor type 2 (HER2 positive patients). Current treatment options in this situation include chemotherapy based palliative treatment in combination withTrastuzumab.

Recent studies have shown that immunotherapy with Nivolumab or Ipilimumab after previous chemotherapy can also improve survival in esophagogastric cancer.

This study assesses the efficacy of two experimental first line treatment strategies: A) Chemo-free immunotherapy with Trastuzumab, Nivolumab and Ipilimumab and B) addition of Nivolumab to the standard regimen (FOLFOX chemotherapy and Trastuzumab).

Detailed Description

Gastric cancer is the fifth most common cancer in the world, and the third leading cause of cancer death in both sexes worldwide.

Surgical resection is currently the only curative treatment option for gastric cancer; however, ~50% of patients have metastatic disease at the time of diagnosis and chemotherapy is the mainstay of palliation in this setting.

Trastuzumab, in combination with chemotherapy, significantly improved survival in patients with overexpression of HER2.

In regard of the very limited therapeutic landscape of HER2 positive EGA, compared to breast cancer, further treatment options to relevantly improve the outcome is warranted. The integration of check-point inhibitors (e.g. Nivolumab, Ipilimumab) into the first line setting either within a chemotherapy-free combination arm or within an intensified standard arm of FOLFOX and trastuzumab with nivolumab may be able to improve the current limited survival of median 14 months.

Eligibility Criteria

Inclusion Criteria

1. All subjects must have inoperable, advanced or metastatic esophagogastric adenocarcinoma

2. Subjects must have HER2-positive disease defined as either IHC 3+ or IHC 2+, the latter in combination with ISH+, as assessed locally on a primary or metastatic tumour (Note: Availability of formalin-fixed paraffin-embedded (FFPE) representative tumor tissue for central confirmation of HER2 is mandatory (Preferably fresh biopsy))

3. Subject must be previously untreated with systemic treatment (including HER 2 inhibitors) given as primary therapy for advanced or metastatic disease.

4. Prior adjuvant or neoadjuvant chemotherapy, radiotherapy and/or chemoradiotherapy are permitted as long as the last administration of the last regimen (whichever was given last) occurred at least 3 months prior to randomization.

5. Subjects must have measurable or evaluable non-measurable disease as assessed by the investigator, according to RECIST v1.1 (Appendix D).

6. ECOG performance status score of 0 or 1 (Appendix B).

7. Screening laboratory values must meet the following criteria (using NCI CTCAE v.4.03 ):

• WBC ≥ 2000/µL
• Neutrophils ≥ 1500/uL
• Platelets ≥ 100x10^3/µL
• Hemoglobin ≥ 9.0 g/dL
• eGFR ≥ 30ml/min (e.g. MDRD formula, appendix G)
• AST ≤ 3.0 x ULN (or ≤ 5.0X ULN if liver metastases are present)
• ALT ≤ 3.0 x ULN (or ≤ 5.0X ULN if liver metastases are present)
• Total Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert Syndrome who must have a total bilirubin level of < 3.0 x ULN)

8. Males and Females, ≥ 18 years of age

9. Subjects must have signed and dated an IRB/IEC approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol-related procedures that are not part of normal subject care.

10. Subjects must be willing and able to comply with scheduled visits, treatment schedule, laboratory tests and other requirements of the study.

11. Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of study drug. Women must not be breastfeeding.

12. WOCBP must use a highly effective method(s) of contraception for a period of 30 days (duration of ovulatory cycle) plus the time required for the investigational drug to undergo 5 half-lives. The terminal half-lives of nivolumab and ipilimumab are approximately 25 days and 15 days, respectively. WOCBP should use an adequate method to avoid pregnancy for approximately 5 months (30 days plus the time required for nivolumab to undergo 5 half-lives) after the last dose of investigational drug.

13. Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for a period of 90 days (duration of sperm turnover) plus the time required for the investigational drug to undergo 5 half-lives. The terminal half-lives of nivolumab and ipilimumab are approximately 25 days and 15 days, respectively. Males who are sexually active with WOCBP must continue contraception for approximately 7 months (90 days plus the time required for nivolumab to undergo 5 half-lives) after the last dose of investigational drug. In addition, male subjects must be willing to refrain from sperm donation during this time.

Exclusion Criteria

1. Malignancies other than disease under study within 5 years prior to inclusion, with the exception of those with a negligible risk of metastasis or death (e.g., expected 5-year OS > 90%) treated with expected curative outcome (such as adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localized prostate cancer treated surgically with curative intent, ductal carcinoma in situ treated surgically with curative intent)
