Effectiveness Study of Ketoconazole and Betamethasone to Treat Fungal Infection and Dermatophytosis (DaVinci)

September 16, 2021 updated by: Ache Laboratorios Farmaceuticos S.A.

Phase 3 Study, Randomized, Double-blind, Parallel to Evaluate Ketoconazole and Betamethasone Dipropionate(Candicort®) Compared to Clotrimazole and Dexamethasone Acetate(Baycuten N®) in Relief of Fungal Infections/Dermatophytosis Symptoms.

To evaluate the no-inferiority of the ketoconazole20mg/g and betamethasone dipropionate 0.64 mg/g association (Candicort®) cream versus clotrimazole 10mg and dexamethasone acetate 0.443 mg/g association (Baycuten N®) cream, general relief of signs and symptoms (erythema, maceration, peeling, blistering / papules / pustules, itching and burning / stinging) 06 (± 1) days after onset treatment.

Study Overview

Detailed Description

Candicort® presents formulation with agents that act both etiological agent of superficial mycosis, with coverage for dermatophytes and more frequent yeast; as inflammation generated by the infectious process or prior to it, in cases of secondary fungal infection in wet or potentially infected eczema fungal dermatitis (atopic dermatitis, seborrhoeic dermatitis, intertrigo, dyshidrosis, contact dermatitis).

The active ingredients ketoconazole and betamethasone act, respectively, on the etiologic agent of the infection and the inflammation generated by the process, and the association of both showed a positive therapeutic response in dermatitis with confirmed secondary infections or potential yeast (analysis carried out in association with sulfate neomycin, aimed to cover bacterial infections together).

160 participants that meet all the inclusion criteria and are not classified in any of the exclusion criteria will be randomly allocated to one of two treatment groups(Candicort® or Baycuten N®) of the study.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage change in the total score of signs and symptoms
Time Frame: 6 (±1) days

Percentage change in the total score of signs and symptoms (erythema, maceration, peeling, blistering /papules /pustules, itching and burning/ stinging) in 6 (±1) days after onset first stage of treatment in relation to the basal.

The total score will be established by the sum of individual scores of the signs and symptoms assessed by the four-point categorical scale (0=absent, 1=mild, 2=moderate, 3=severe), ranging from 0 to 18 points.

The percentage change in the total score of signs and symptoms will be calculated by the following expression:

VTSS(%) = [(TSS0 -TSS6)/ TSS0]*100

TSS0: total score of signs and symptoms (erythema, maceration, peeling, blistering /papules /pustules, itching and burning/ stinging) in 0 day.

TSS6: total score of signs and symptoms (erythema, maceration, peeling, blistering /papules /pustules, itching and burning/ stinging) in 6 (±1) days after onset first stage of treatment
