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).
|Condition or disease||Intervention/treatment||Phase|
|Gastric Cancer Esophageal Cancer Adenocarcinoma Gastric HER2 Positive Gastric Cancer Metastatic Gastric Cancer GastroEsophageal Cancer||Drug: Nivolumab Drug: Ipilimumab||Phase 2|
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.

- Overall Survival [ Time Frame: Milestone at 12 months, max observation period 48 months ]Overall survival including milestone rate at 12 months
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [ Time Frame: 48 months ]according to Common Terminology Criteria for Adverse Events and to the obtained data on vital signs, clinical parameters and feasibility of the regimen
- Progression Free Survival [ Time Frame: 48 months ]Response Evaluation Criteria in Solid Tumors (RECIST 1.1.)
- Response Rate [ Time Frame: 15 months ]Response Rate (RR) according to RECIST v1.1
- Health related Quality of Life [ Time Frame: 48 months ]
EORTC QLQ-C30 (European Organisation for Research and Treatment of Cancer - Quality of Life Core Questionnaire (30 items) Version 3.0. The QLQ-C30 is composed of multi-item scales and single-item measures, including five functional scales, three symptom scales, a global health status / QoL scale, and six single items.
All of the scales and single-item measures have a score range from 0 to 100. A high score shows a high response level. A high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems
- Health related Quality of Life [ Time Frame: 48 months ]EORTC STO-22 (European Organisation for Research and Treatment of Cancer - Quality of Life Questionnaire Gastric Module (STO = stomach) (22 items), comprising five multi-item and four single-item subscales. The multi-item subscales include questions about dysphagia (4 items), dietary restriction (5 items), pain (3 items), upper gastro-esophageal symptoms such as reflux (3 items), and emotional problems such as anxiety (3 items). The single-item subscales include questions related to four gastric cancer-specific symptoms: dry mouth, body image, hair loss, and problems with taste. Items are assessed on a 4-level numerical scale with 1= "not at all", 2= "a little", 3= "quite a bit", and 4= "very much". Scores are linearly converted and summated into a scaled score from 0 to 100, with a higher score representing a worse QOL.
