Brief Summary:
This is an open label, phase II, multi-site trial evaluating the efficacy and safety of the combination of 5-FU, oxaliplatin, nal-IRI, and immunotherapy (plus trastuzumab for HER2-positive tumors) as first-line therapy for participants with advanced Esophageal and Gastric Adenocarcinoma (EGA). The investigators hypothesize that this drug combination will be better tolerated than current first-line chemotherapy combinations for this disease.

Condition or disease Intervention/treatment Phase
Esophageal Adenocarcinoma Gastric Adenocarcinoma Drug: Nal-IRI Drug: Oxaliplatin Drug: 5-FU Drug: Trastuzumab Drug: Pembrolizumab Drug: Nivolumab Phase 2

Detailed Description:

This is an open label, phase II, multi-site trial evaluating the efficacy and safety of the combination of 5-FU, oxaliplatin, nal-IRI, and immunotherapy (plus trastuzumab for HER2-positive tumors) as first-line therapy for participants with advanced Esophageal and Gastric Adenocarcinoma (EGA).

Participants will be enrolled into one of four cohorts. Participants in Cohort 1 (HER-2 negative) will receive 5-FU, oxaliplatin and nal-IRI. Cohort 3 (HER-2 negative) will use nivolumab in addition to 5-FU, oxaliplatin and nal-IRI. Participants in Cohort 2 (HER-2 positive) will receive trastuzumab in addition to 5-FU, oxaliplatin and nal-IRI. Cohort 4 (HER-2 positive) will also include pembrolizumab in addition to trastuzumab, 5-FU, oxaliplatin and nal-IRI.

Chemotherapy doses will be the same for all cohorts and will follow similar modifications for toxicities. Agents will be administered as per institutional standards when similar regimens (such as FOLFIRINOX, FOLFOX, and trastuzumab) are used.

Cohort 1 (HER2-negative tumors): Up to 13 evaluable participants will be accrued to Cohort 1.

Cohort 2 (HER2-positive tumors): Up to a total of 6 subjects will be enrolled to evaluate the safety and tolerability of the proposed 5-Fluorouracil, Oxaliplatin and liposomal Irinotecan combination in HER2-positive subjects.

Cohort 3 (HER-2 negative tumors):12 participants will be enrolled during stage 1. If at most 5 objective responses per RECIST 1.1 are observed, then further enrollment will be halted. Otherwise, 15 additional participants will be enrolled for a total number of 27.

Cohort 4 (HER-2 positive tumors): treated with oxaliplatin, Nal-IRI and trastuzumab in combination with pembrolizumab. A total of up to 6 subjects will be accrued to evaluate safety and tolerability.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Cohort 1: Objective Response Rate (ORR) [ Time Frame: up to 1 year ]
    ORR will be calculated by combining the number of participants who achieve complete response and partial response per RECIST 1.1 criteria, from the start of treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the start of treatment). An ORR of 40% or less for proposed combination of 5-Fluorouracil, Oxaliplatin and nal-IRI during 1st line treatment of advanced esophageal and gastric adenocarcinoma in HER2-negative subjects will be considered as unacceptably low. The number and frequencies of objectives responses will be summarized in tabular format. The ORR will be reported along with the corresponding one-sided 90% confidence intervals.

  2. Cohort 3: Objective Response Rate (ORR) [ Time Frame: up to 1 year ]
    ORR will be calculated by combining the number of participants who achieve complete response and partial response per RECIST 1.1 criteria, from the start of treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the start of treatment). An ORR of 45% or less for proposed combination of 5-Fluorouracil, Oxaliplatin, nal-IRI and Nivolumab during 1st line treatment of advanced esophageal and gastric adenocarcinoma in HER2-negative subjects will be considered as unacceptably low. The number and frequencies of objectives responses will be summarized in tabular format. The ORR will be reported along with the corresponding one-sided 90% confidence intervals.

  3. Cohorts 2 and 4: Incidence of Adverse Events [ Time Frame: up to 1 year ]
    The primary objective of cohorts 2 and 4 (HER2-positive EGA) is to evaluate safety and tolerability of the studied drug combination. Toxicities and adverse events will be summarized by type and severity in tabular format.


Secondary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: up to 2 years ]
    PFS will be defined from the date study enrollment to the date of progression event or death. If a participant does not experience a progression event at the end of the follow-up period, then the PFS will be censored at the last assessment date. PFS will be analyzed using the Kaplan-Meier method. Median PFS will be reported along with the corresponding 90% confidence interval which will be constructed using the nonparametric Brookmeyer-Crooley method.

  2. Disease Control Rate (DCR) [ Time Frame: up to 1 year ]
    The DCR is the proportion of all participants with stable disease (SD) for 8 weeks, or partial response (PR), or complete response (CR) according to RECIST 1.1, from the start of treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the start of treatment).DCR will be reported along with the corresponding 90% confidence intervals which will be constructed using the Wilson score method.

  3. Progression Free Survival at 6 months [ Time Frame: up to 6 months ]
    PFS will be defined from the date study enrollment to the date of progression event or death. If a participant does not experience a progression event at the end of the follow-up period, then the PFS will be censored at the last assessment date. PFS will be analyzed using the Kaplan-Meier method. Median PFS will be reported along with the corresponding 90% confidence interval which will be constructed using the nonparametric Brookmeyer-Crooley method.

  4. Progression Free Survival at 12 months [ Time Frame: up to 1 year ]
    PFS will be defined from the date study enrollment to the date of progression event or death. If a participant does not experience a progression event at the end of the follow-up period, then the PFS will be censored at the last assessment date. PFS will be analyzed using the Kaplan-Meier method. Median PFS will be reported along with the corresponding 90% confidence interval which will be constructed using the nonparametric Brookmeyer-Crooley method.

  5. Cohorts 1 and 3: Incidence of Adverse Events [ Time Frame: up to 1 year ]
    Toxicities and adverse events will be summarized in tabular format, stratified by type and severity

  6. Cohorts 2 and 4: Overall Response Rate [ Time Frame: up to 1 year ]
    ORR will be calculated by combining the number of participants who achieve complete response and partial response per RECIST 1.1 criteria, from the start of treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the start of treatment).
