Condition

Fungal Infections

Yeast Infections

Treatment

N/A

Clinical Study ID

NCT03320486
GDN 018/16
  • Ages 18-65
  • All Genders

Study Summary

The main purpose of this study is to demonstrate that dapaconazole cream 2% (experimental drug) is non-inferior to ketoconazole cream 2% (Nizoral® - active comparator) for the treatment of dermatological lesions of Tinea pedis, when applied to the skin (topically) once daily during 28 days. Additionally, the safety and tolerability aspects will be evaluated in a descriptive way, through the observation of the incidence of adverse events.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Participants aged from 18 to 65 years old, male, or female with no childbearingpotential or who are using an effective contraceptive method and who do not plan tobecome pregnant during the study period.

  • Presence of dermatological lesion(s) of Tinea pedis, with a global clinical severityscore ≥ 4, being a minimum score of 2 for itching or desquamation/maceration and aminimum score of 2 for erythema, having, also, the diagnosis confirmed by directmycological (KOH) test.

  • No previous treatment with antimycotic medication, in the last 2 months, for thecurrent dermatologic lesion.

  • No evidence of other significant diseases, that, at the investigator's discretion, mayaffect the participation in the clinical trial, in accordance with the protocolrequirements.

  • Ability to understand the nature and the objective of the clinical trial, includingthe risks and possible side effects; intention to cooperate with the investigator andact in accordance with the protocol requirements, as confirmed by the informed consentform signature.

Exclusion

Exclusion Criteria:

  • Existing hepatic and/or renal diseases or other pathologic findings, which mightinterfere with the safety and tolerability of the active ingredients.

  • Screening laboratory tests presenting deviations deemed as clinically significant,which, due to possible risks, prevents the participation in clinical trial.

  • Known hypersensitivity to ketoconazole or to chemically related compounds (azoles) orto the compounds of the investigational products.

  • Participants with severe or multiple drugs allergies, unless judged by theinvestigator as not clinically relevant to the participation in the clinical trial.

  • Positive anti human immunodeficiency virus (anti-HIV) test, positive Hepatitis BSurface Antigen (HBs-Ag) test or positive anti hepatitis C virus (anti-HCV) test.

  • Treatment, within 3 months prior to the start of the clinical trial treatment, withany drug known to have a well-established toxic potential to major organs.

  • Pregnant or lactating women

  • Participation in any clinical trial, or intake of any investigational product, withinthe last twelve months prior to the inclusion in the clinical trial.

  • Presence of onychomycosis.

  • Presence of "Moccasin type" Tinea pedis.

  • Presence of infected Tinea pedis, or any other infection or pathology that may confusethe treatment evaluation.

  • History of drug addiction.

  • Diseases that may alter the immune system and, consequently, the host's response tothe fungal presence (immunosuppressed participants), as well as the use of systemicimmunosuppressive drugs, chemotherapy or radiotherapy, during the 3 months prior tothe start of treatment.

  • Use of drugs that may interfere with the assessment of the results, as well as use oftopical immunosuppressants, topical antibiotics or topical corticosteroids, within 2months prior to the start of treatment.

  • Use of antipruriginous drugs, including antihistaminics, within 72 hours prior to thestart of treatment.

  • History of alcohol dependence and/or regular intake of alcoholic food or beveragescontaining ≥ 20 g of pure ethanol per day.

  • Any prior treatment for the present lesion which, at investigator discretion, mayinterfere with the objectives of the clinical trial.

  • Participants who might be non-compliant to the study treatment and/or to therequirements and procedures of the protocol.

  • Participants who are unable to understand written and verbal instructions, inparticular those regarding the risks and inconveniences to which they will be exposedduring the participation in the clinical trial.

Study Description

This is a non-inferiority, phase 3, multicenter, double-blind, randomized (allocation of treatment), balanced, controlled (active comparator) trial, with two parallel groups in a 1:1 proportion.

Randomization will depend on inclusion/exclusion criteria, taking into account the confirmation of diagnosis by the direct mycological test performed during the screening phase. However, cases whose diagnosis is not additionally confirmed by positive fungal culture (sampled during the screening phase) will be excluded from the efficacy analysis.

Participants will show up to the clinic, for treatment, during 42 consecutive days, when one of the investigational products (according to the randomization) will be applied by a blind member of the study staff. A non-blind member of the study staff will weigh the corresponding investigational product and pass on to the blind member only a spatula with the weighed product, in order to maintain the blinded aspect of the trial.

For exploratory purposes, clinical and mycological evaluations will also be performed after 7 and after 14 days of treatment.

Safety analysis will be performed considering all the randomized patients to which at least one dose of the investigational products has been applied, regardless of the result of the fungal culture.

Conclusion of non-inferiority will be based on the per protocol set. It will be deemed as per protocol those participants who do not miss more than 20% of the applications and, also, no more than four consecutive application days.
