Phase 3

Conditions
Onychomycosis

Drug: MOB015B
Drug: Vehicle (Placebo Comparator)
Registration Number
NCT05279846
Lead Sponsor
Moberg Pharma AB
Brief Summary

This is a Phase 3 multicenter, double-blind study to evaluate the safety and efficacy of vehicle-controlled topical MOB015B in the treatment of Distal Subungual Onychomycosis (DSO)

Detailed Description

Distal subungual onychomycosis (DSO) is the most common form of Onychomycosis, in which fungi invade the underside of the nail plate. The infection may worsen, spread to other uninfected areas or infect other people. Without treatment the disease may have an impact on an individual's quality of life. MOB015B is a newly developed topical solution for the treatment of nail fungus (onychomycosis) containing the active antifungal ingredient terbinafine. All ingredients in MOB015B have a well-established use in approved pharmaceuticals for dermatological use. The purpose of this study is to evaluate the efficacy and safety of a new reduced dose treatment regimen of MOB015B whereby the investigational medicinal product (IMP) is applied daily for 8 weeks and then reduced to once weekly treatment for 40 weeks.

Target Recruitment
350
Inclusion Criteria
  1. Males or females 12 to 75 years of age
  2. Distal subungual onychomycosis of at least one of the great toenail(s) affecting 20% to 60% of the target great toenail (verified by a central blinded assessor before randomization)
  3. Positive KOH microscopy and culture for dermatophytes in the target toenail
  4. Ability of the great toenail to grow (e.g., subject reports cutting toenails at least monthly)
  5. Signed written informed consent and assent (if applicable)
Exclusion Criteria
  1. Proximal subungual onychomycosis, superficial white onychomycosis, or significant dystrophy judged clinically by the blinded assessor or by the Investigator that may interfere with clinical evaluation of onychomycosis
  2. Distal subungual onychomycosis where disease involvement has extended into the proximal portion of the target toenail and the unaffected proximal nail is less than 3 mm measured from proximal nail fold
  3. Target toenail thickness more than 3 mm measured at the distal end
  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) or severe onychorrhexis on the target toenail
  6. Nail conditions other than DSO that are known to cause abnormal nail appearance, presence of melanonychia or subungual hematoma that could obscure visualization of nail clearing
  7. Other microbial infections of the target toenail, for example, candida or mold infections without isolation of a dermatophyte
  8. Previous target toenail surgery (within 6 months) with any residual disfigurement that will impact efficacy outcome or will not allow nail to grow normally, as judged by the Investigator
  9. Topical treatment of the toenails with other antifungal medication within 6 weeks before Screening/Visit 1
  10. History of failing oral therapy for onychomycosis within the past 3 years, or inability for nail to appear normal due to trauma, as judged by the Investigator
  11. Systemic use of antifungal treatment within 6 months before Screening/Visit 1
  12. Moderate to severe moccasin tinea pedis that require prolonged topical antifungal treatment or oral antifungal treatment should be excluded. Subjects with symptomatic interdigital tinea pedis or mild moccasin type tinea pedis will be screen failed. However, However, they will be allowed to enter the study after appropriate effective treatment and washout period as per Investigator judgment.
  13. Signs of severe peripheral circulatory insufficiency as determined by significantly diminished/lack of pedal pulse on either foot
  14. Subjects with a current or past history of psoriasis and/or lichen planus
  15. Subjects with poorly controlled (or uncontrolled) diabetes mellitus as determined by HbA1c of > 8%
  16. Known immunodeficiency, i.e., congenital immunodeficiency, acquired immunodeficiency, iatrogenic by immunosuppressive drugs like cytostatics or by radiation therapy or immunomodulatory medications (e.g., TNF inhibitors)
  17. Participation in another clinical trial with an investigational drug or device during the previous 3 months before enrollment/baseline and for the duration of this study
  18. Known allergy to any of the tested treatment products
  19. Female subjects who are pregnant or breastfeeding; or intend to conceive a child during the duration of the study (52 weeks).
  20. Subjects previously randomized to any study involving MOB015B treatment/exposure
  21. History of, or current drug or alcohol abuse that would interfere with a subject's ability to participate in the study as determined by the Investigator
  22. Psychiatric condition that might limit the participation in the study and/or that lead to the assumption that the subject'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 the same study site, or subject who is an employee of the Sponsor/designee
  24. Subjects who are institutionalized because of legal or regulatory order
  25. Any diseases or circumstances in which the subject should not participate in the study in the opinion of the Investigator
