Study summary

This is an open-label, maximal use study to evaluate whether luliconazole in plasma acts as an inhibitor of cytochrome P2C19 (CYP2C19) as measured by circulating levels of omeprazole before and after treatment with a maximum dose of luliconazole cream 1% in participants with moderate to severe tinea pedis and tinea cruris.

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

  • Participants with a clinical diagnosis of moderate to severe interdigital tinea pedis, as defined by a Physician's Global Assessment (PGA) score of 2 or 3 on both feet, and moderate to severe tinea cruris, as defined by a PGA score of 2 or 3
  • Participants with a mycological diagnosis of tinea pedis and tinea cruris confirmed by the detection of fungal hyphae on a microscopic potassium hydroxide (KOH) wet mount
  • Participants must be in good general health and free of any disease that might interfere with study evaluations
  • Participants with the ability and willingness to follow all study procedures, attend all scheduled visits, and successfully complete the study

Exclusion criteria

Exclusion Criteria:

  • Female participants who are pregnant and/or nursing or planning a pregnancy during the course of the trial
  • Participants who are
  • Participants who have a recent history of or currently known drug or alcohol abuse
  • Participants with a history of intolerance or to imidazole compounds, proton pump inhibitors, or the inactive components of luliconazole cream 1% or omeprazole
  • Participants with a life-threatening condition within the last 6 months
  • Participants with uncontrolled diabetes mellitus
  • Participants who are unable to communicate or cooperate with the Investigator
  • Participants using medications for treatment of tinea pedis and/or tinea cruris (see Investigator for length of time prior to study start)
  • Participants receiving concomitant drugs that are known to inhibit and/or induce CYP2C19 and/or , or that interact with omeprazole
  • Because of the potential for drug interaction with luliconazole, administration with medications that are known to be substrates of CYP3A4, CYP2B6, CYP2C8, and CYP2C19 should be carefully monitored
Terms in these criteria, in plain language(3)

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

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.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

What researchers measure

Primary outcomes

  1. Circulating Levels (Plasma Concentration) of Omeprazole Prior to Treatment With Luliconazole Cream 1%

    Circulating plasma levels of omeprazole were measured using validated liquid chromatography with tandem mass spectrometry detection (LS/MS-MS) methods. The range for omeprazole determination was 4.64-9.27 nanograms/milliliter (ng/mL). Serial blood sampling occurred in each enrolled participant up to 24 hours post treatment (Day 1) with omeprazole (before the start of luliconazole cream 1% treatment on Day 2).

    Time frame: 15 minutes predose; 15, 30, 45, and 60 minutes postdose; and 1.5, 2, 2.5, 3, 4, 6, 8, 10, and 24 hours postdose of omeprazole on Day 1

  2. Circulating Levels (Plasma Concentration) of Omeprazole After 1 Week of Treatment With Luliconazole Cream 1%

    Circulating plasma levels of omeprazole were measured using validated LS/MS-MS methods. The range for omeprazole determination was 4.64-9.27 ng/mL. Serial blood sampling occurred in each enrolled participant up to 24 hours post treatment (Day 8) with omeprazole (after using luliconazole cream 1% treatment for 1 week).

    Time frame: 15 minutes predose; 15, 30, 45, and 60 minutes postdose; and 1.5, 2, 2.5, 3, 4, 6, 8, 10, and 24 hours postdose of omeprazole on Day 8
