Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Healthy male or non-pregnant female aged ≥ 18 years
  2. Subjects must have provided IRB approved written .
  3. Subjects must have clinical diagnosis of tinea versicolor.
  4. Subjects must be willing to refrain from using all other tinea versicolor medications or antifungals during the study, other than the product.
  5. Female Subjects of (excluding women who are premenarchal, surgically sterilized (by hysterectomy) or for at least 1 year), in addition to having a negative urine pregnancy test, must be willing to use an acceptable form of during the study from the day of the first dose administration to 30 days after the last administration of study drug.

Exclusion criteria

Exclusion Criteria:

  1. Female Subjects who are pregnant, nursing or planning to become pregnant during study participation.
  2. Subjects with a history of or allergy to ketoconazole, other imidazole antifungals, and/or any of the study medication ingredients.
  3. Subjects with the presence of any skin condition that would interfere with the diagnosis or assessment of tinea versicolor (e.g., vitiligo, pityriasis alba, post inflammatory hypopigmentation and hyperpigmentation, seborrheic dermatitis, pityriasis rosea, guttate psoriasis, tinea corporis, nummular eczema, secondary syphilis, confluent reticulated papillomatosis of Gougerot and Carteaud, and mycosis fungoides).
  4. Treatment for tinea versicolor within the past 6 months that had been unresponsive to prescription topical or oral antifungals.
Terms in these criteria, in plain language(6)

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

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.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

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 Mar 12, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
