Summary
To evaluate the efficacy of maintenance therapies following completion of standard first-line chemotherapy in patients with locally advanced or metastatic HER-2 positive or HER-2 negative oesophago-gastric adenocarcinomas.
Research Details
  • This is a prospective, open label, multicentre, randomised phase II clinical trial. An adaptive trial design is proposed to allow ineffective treatments to be discontinued early, and to potentially add novel treatment arms as the trial progresses.

    Patients will initially receive standard chemotherapy for their locally advanced or metastatic oesophago-gastric adenocarcinoma, according to local practice based upon their HER-2 status (tested locally). In order to be eligible for trial entry, HER-2 negative patients should have received a platinum-fluoropyrimidine based chemotherapy doublet or triplet (Arm A), whilst HER-2 positive patients (IHC 3+ or IHC 2+ and FISH positive) should have received cisplatin in combination with either capecitabine or 5-FU (CX or CF) plus trastuzumab chemotherapy (Arm B). Potentially eligible patients will be registered with the trials office whilst undergoing first line chemotherapy.

    Patients will then become eligible for trial recruitment and randomization following completion of at least 6 cycles of standard chemotherapy with ≥SD (stable disease) on the end-of-treatment CT scan. Eligible patients will then be randomised according to HER-2 status as follows:

    - HER-2 positive patients (~20%) will be currently not be randomised and will be assigned maintenance single-agent trastuzumab (current UK standard), a comparator arm is in development.

    - HER-2 negative patients (~80%) will be randomised in a 1:1:1 fashion between surveillance only (current UK standard), maintenance capecitabine, or maintenance immuno-modulatory therapy (anti-PD-L1 antibody)

    Patients will be stratified according to: locally advanced disease versus metastatic disease, and performance status (0 versus 1 versus 2).

    Review of patients will occur every 4 weeks in the observation only arm. In maintenance therapy arms, patients will be reviewed every 3 or every 4 weeks depending upon the treatment strategy. CT assessments of response will occur every 12 weeks (3 months) in all arms of the trial. Treatment will be continued indefinitely until the occurrence of either disease progression, unacceptable toxicity, or patient withdrawal for another reason.

    The trial is being run from the RMH GI clinical trials unit with Professor David Cunningham as the over-arching CI. Effective arms in the phase II portion of the trial may be taken forward into a phase III maintenance trial powered for overall survival. It is also hoped that, as more robust data becomes available for other biomarker-selected populations (e.g. MET-positive, FGFR-amplified), it may be possible to amend the overall trial design to incorporate these biomarker-targeted maintenance therapies in the HER-2 negative population.

Participant Inclusion Criteria
    Inclusion Criteria - All Patients

    - Histologically verified inoperable locally advanced or metastatic adenocarcinoma of the oesophagus, oesophago-gastric junction, or stomach.

    - Completion of at least 6 cycles of first-line chemotherapy for locally advanced / metastatic disease (this must have included a platinum and fluoropyrimidine in all cases; HER-2 positive patients must have received trastuzumab alongside chemotherapy) with > stable disease on the end of treatment CT scan.

    - Disease which, following first-line chemotherapy, remains inoperable and unsuitable for definitive chemoradiotherapy.

    - Able to proceed with maintenance treatment within 28 days of the last day of the last cycle of chemotherapy.

    - Formalin fixed paraffin embedded (FFPE) blocks of diagnostic tissue available for biomarker analysis.

    - Uni-dimensionally measurable disease (CT or MRI as per RECIST).

    - Any prior chemotherapy or radiotherapy in the adjuvant setting must have been completed at least 6 months prior to the first occurrence of metastatic disease.

    - No prior radiotherapy in the advanced disease setting. Patients receiving palliative radiotherapy to sites of disease that are not measurable may be eligible and should be discussed with the Chief Investigator.

    - Male/female patients aged ≥18 years.

    - WHO Performance status 0, 1 or 2.

    - Patients should have a projected life expectancy of at least 3 months.
