Study summary

The primary objective of this study is to evaluate the efficacy of topical MOB015B in patients with mild to moderate distal subungual onychomycosis (DSO).

The secondary objective is to evaluate the safety of topical MOB015B in patients with mild to moderate DSO.

Read the detailed description

Male or female subjects aged between 12 and 75 years with confirmed DSO involving 20-60% of at least one great toenail will be screened for randomization in this study. The diagnosis of DSO will be confirmed prior to randomization through a positive culture of dermatophytes. In addition, a central blinded assessment of the clinical disease involvement (i.e., affected nail area) will be performed at Screening. Subjects have to meet all eligibility criteria before being randomized in to the study.

Eligible subjects will be randomized to the investigational medicinal products (MOB015B or vehicle) in a ratio of 2:1. The investigational medicinal products (IMPs) will be applied to all affected fingernails and/or toenails for 48 weeks once daily at bedtime. However, fingernails will not be assessed for efficacy.

Since both the IMPs are indistinguishable in appearance and mode of administration, the study will be performed as a double-blind study, i.e., both the investigator and the subject will remain blinded throughout the entire study.

After a 4-week follow-up period without IMP treatment the end of study (EoS) Visit will be performed at Week 52 (Visit 7). The primary efficacy variable will be assessed at Week 52. The end of the clinical study for each individual subject is defined as the EoS Visit at Week 52 (Visit 7). The end of the clinical study is defined as the last visit of the last subject in the study.

Inclusion criteria

  1. Males or females 12 - 75 years of age
  2. Distal subungual onychomycosis (DSO) of at least one of the great toenail(s) affecting 20% to 60% of the target nail
  3. Positive culture for dermatophytes
  4. Written

Exclusion criteria

Exclusion Criteria:

  1. Proximal subungual onychomycosis
  2. Distal subungual onychomycosis of both great toenails where involvement has extended into the proximal portion of the target nail (unaffected proximal nail is less than 3 mm)
  3. Target toenail thickness more than 3 mm
  4. "Spike" of onychomycosis extending to eponychium of the target toenail
  5. Presence of dermatophytoma (defined as thick masses of fungal hyphae and necrotic keratin between the nail plate and nail bed) on the target nail
  6. Other conditions than DSO known to cause abnormal nail appearance
  7. Presence of toenail infection other than dermatophytes
  8. Previous target toenail surgery with any residual disfigurement
  9. Topical treatment of the nails with other antifungal medication within 6 weeks before screening/Visit 1
  10. Systemic use of antifungal treatment within 6 months before screening/visit 1
  11. Severe moccasin tinea pedis
  12. Signs of severe peripheral circulatory insufficiency
  13. Uncontrolled diabetes mellitus
  14. Known immunodeficiency
  15. Participation in another clinical trial with an drug or device during the previous 3 months before Baseline/ Visit 2
  16. Known allergy to any of the tested treatment products
  17. A positive pregnancy test at Baseline/Visit 2 indicating pregnancy in a woman of or a premenarche subject
  18. Females who are pregnant or breastfeeding
  19. Men who have female sexual partners of child-bearing potential and sexually active women of child-bearing potential who are not practicing an acceptable method of , or who will not remain abstinent through the trial.
  20. Patients previously randomized in this study
  21. History of, or current drug or alcohol abuse
  22. Psychiatric condition that might limit the participation in the study and/or that lead to the assumption that the patient's ability to completely understand the consequences of consent is missing
  23. Close affiliation with the investigator (e.g. a close relative) or persons working at a study site, or patient who is an employee of the sponsor's company
  24. Patients who are institutionalized because of legal or regulatory order
  25. Any diseases or circumstances in which the patient should not participate in the study in the opinion of the investigator
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.

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.

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.

    Time frame: Week 52

Secondary outcomes

  1. Subjects with mycological cure of the target toe nail at Week 52

    Mycological cure was defined as negative fungal culture of dermatophytes and negative direct KOH microscopy of the target toenail.

    Time frame: Week 52

  2. Subjects with treatment success of the target toe nail at Week 52

    Treatment success was defined as negative fungal culture of dermatophytes, negative direct KOH microscopy and ≤10% clinical disease involvement of the target toenail.

    Time frame: Week 52
