About this study
Official title: Modified FOLFOX Plus/Minus Nivolumab and Ipilimumab vs. FLOT Plus Nivolumab in Patients With Previously Untreated Advanced or Metastatic Adenocarcinoma of the Stomach or Gastroesophageal Junction - A Randomized Phase 2 Trial.
Patients with Her2 negative, previously untreated metastatic esophagogastric adenocarcinoma will be treated with modified FOLFOX, with modified FOLFOX plus Nivolumab and Ipilimumab or FLOT plus Nivolumab. The groups will be compared for time until progression of the disease (primary endpoint) as well as for response to the treatment, overall survival, safety/tolerability of the treatment and quality of life.
Read the detailed description
This is a randomized, open labelled multicenter phase II trial, followed by a non-randomized arm.
Patients with Her2 negative, previously untreated metastatic esophagogastric adenocarcinoma will be randomized to receive either modified FOLFOX (Oxaliplatin at a dose of 85 mg/m² iv over two hours (day 1), Leucovorin at a dose of 400 mg/m2 iv over two hours (day 1), Fluorouracil at a dose of 400 mg/m² iv bolus (day 1), and Fluorouracil at a dose of 2400 mg/m² iv continuous infusion over 44 hours (day 1+2), every 2 weeks) alone, modified FOLFOX plus Nivolumab (240mg "Flatdose" i.v. d1 every 2 weeks) and Ipilimumab (1mg/kg i.v. d1 every 6 weeks) or sequential treatment (three cycles of induction chemotherapy with modified FOLFOX followed by immunotherapy consisting of 4 administrations of Nivolumab at 240mg "Flatdose" i.v. d1 every 2 weeks and 2 administrations of Ipilimumab at 1mg/kg i.v. d1 every 6 weeks, this sequence may be repeated starting two weeks after last administration of immunotherapy once, or, if medically reasonable, for an unlimited number of repetitions upon investigator decision; after completion or discontinuation of chemotherapy, immunotherapy will be continued consisting of Nivolumab at 240mg "Flatdose" i.v. d1 every 2 weeks and Ipilimumab at 1mg/kg i.v. d1 every 6 weeks). In a non-randomized arm, patients receive Nivolumab 240mg "Flatdose" i.v. d1 every 2 weeks and FLOT (Docetaxel 50mg/², Oxaliplatin 85 mg/m², leucovorin 200 mg/m² on day 1 and fluorouracil 2600 mg/m² IV continuous infusion over 24 hours) every 2 weeks. After completion or discontinuation of chemotherapy, immunotherapy may be continued (Nivolumab at 240mg "Flatdose" i.v. d1 every 2 weeks).
Treatment in every arm will be given for a maximum of 24 months or until disease progression or inacceptable toxicity or end of study treatment.
The primary objective is to determine the clinical performance of the experimental regimen in patients with previously untreated HER2 negative locally advanced or metastatic esophagogastric adenocarcinoma in terms of progression free survival (acc. to RECIST v1.1).
Secondary objectives are to determine efficacy in terms of objective response rate (acc. to RECIST v1.1) and overall survival, as well as tolerability (acc. to NCI CTC AE v4.03) of the experimental regimen. In addition histopathological types and molecular parameters such as immune cell composition and PD-L1 expression as determined by quantitative mRNA (RT-PCR) will be correlated with efficacy in an exploratory analysis.
257 subjects (59 in the control arm, 89 in the experimental treatment group A1, 59 in the experimental treatment group A2 and 50 in the experimental treatment group C) will be enrolled.

Key inclusion criteria (24 listed)
- All subjects must have inoperable, advanced or metastatic GC or GEJ adenocarcinoma.
- Subjects must have HER2-negative disease defined as either IHC 0 or I+ or IHC 2+, the latter in combination with ISH-, as assessed locally on a primary or metastatic tumour.
- Subject must be previously untreated with systemic treatment given as primary therapy for advanced or metastatic disease.
- 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 6 months prior to randomization/enrolment.
- Palliative radiotherapy is allowed and must be completed 2 weeks prior to randomization/enrolment.
Key exclusion criteria (17 listed)
- 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)
- Subjects with untreated symptomatic CNS metastases. Subjects are eligible if CNS metastases are asymptomatic (this includes patients with unknown CNS metastatic status who have no clinical signs of CNS metastases) or those with asymptomatic or symptomatic CNS who are adequately treated and are neurologically returned to baseline (except for residual signs or symptoms related to the CNS treatment) for at least 2 weeks prior to randomization/enrolment. In addition, subjects must be either off corticosteroids, or on a stable or decreasing dose of < 10 mg daily prednisone (or equivalent) for at least 2 weeks prior to randomization/enrolment. Patients with unknown CNS metastatic status and any clinical signs indicative of CNS metastases are eligible if CNS metastases are excluded using CT and/or MRI scans, or CNS metastases are confirmed but adequately treated as described above.
- Subjects with active, known, or suspected autoimmune disease. Subjects with Type I diabetes mellitus, residual hypothyroidism due to autoimmune thyroiditis only requiring hormone replacement, or skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment are permitted to enroll. For any cases of uncertainty, it is recommended that the medical monitor be consulted prior to signing informed consent.
- Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids, and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.
- Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 24 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 27 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival (PFS) Arm A and B (time frame: Up to 3 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03647969, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Aug 2024.
