Study summary

Patients taking chemotherapeutic agents often do not comply well with their dosing regiment since many of these medications cause a metallic taste in the mouth. The primary intent is to determine the effectiveness of the oral rinse in reducing the metallic taste in the mouth associated with various chemotherapeutic agents. This clinical study a randomized, double-blind, single-treatment, parallel design with a placebo as the control. The duration of the trial will be 1 month.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Experimental
    Metaqil™ Oral Rinse

    In this arm the test article, Metaqil ™ oral rinse, a proprietary formulation of agents including Monk fruit extract, which can minimize the metallic taste in the mouth caused by the patient's medications. Subjects rinse twice a day with 10 mL of the oral rinse for 30 seconds for 30 days. They will note, in the daily oral hygiene diary, the date and time of brushing and rinsing.

    Device: Metaqil™ Oral Rinse

  • Placebo comparator
    Placebo Oral Rinse

    This arm will use a placebo with out the active ingredients same way the experimental arm do.

What researchers measure

Primary outcomes

  1. Relief of medication associated metallic taste

    Have patient complete a VAS ( visual analogue scale) scoring of the degree of metallic taste in the mouth as well as a VAS scoring of the amount of relief of the metallic taste..

    Time frame: 4 weeks

Secondary outcomes

  1. Safety evaluation of the test Oral Rinse

    Evaluate extra- and intra- oral areas for any mucosal irritation or pathology.

    Time frame: 4 Weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2017 to primary completion in Sep 2018, 15 months.

Of 18 interventional studies with no phase under Dysgeusia, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 16. This study's 15 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 22, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
