Role of Microbiome as a Biomarkers in Locoregionally-Advanced Oropharyngeal Squamous Cell Carcinoma 2
Canada30 participantsStarted 2019-07-02
Plain-language summary
This is a single-centre feasibility study designed to assess the safety, tolerability and engraftment of MET-4 bacterial strains when given in combination with chemoradiotherapy (CRT). The study will involve a prospective cohort of 30 patients diagnosed with Locoregionally-Advanced Oropharyngeal Squamous Cell Carcinoma (LA-OPSCC) to be treated with CRT as per standard of care at Princess Margaret Cancer Centre. All patients enrolled will receive MET-4 in addition to standard CRT. MET-4 is administered orally as an initial daily loading dose over 2 days followed by a daily maintenance dose of MET-4 and will be administered until week 4 of CRT or unacceptable toxicity whichever occurs earlier and in the absence of criteria to discontinue MET-4. This protocol does not determine eligibility to receive treatment with concurrent CRT. It is anticipated that patient accrual will be completed within 12 months.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Toxicity defined by CTCAE v.5.0.
Timeframe: 1 year
2
Relative abundance of MET-4 associated bacterial strains in stool samples collected at week 4, end of CRT and 2-month follow-up timepoints.
. Any condition that, in the opinion of the Investigator, would interfere with patient safety, or evaluation of the collected specimen and interpretation of study result.
. Subjects unable to swallow orally administered medications or any subjects with gastrointestinal disorders likely to interfere with absorption (e.g. bowel obstruction, short gut syndrome, blind loop syndrome, ileostomy etc). Subjects with colostomies may be enrolled.
. Pregnant or planning to get pregnant in the next 6 months.
