Efficacy and Safety Evaluation of the Intralesional Recombinant Human Epidermal Growth Factor (rhEGF) in Subjects With Diabetic Foot Ulcer.

Summary

Phase III clinical trial, multicenter, controlled, randomized, double-blind, with two parallel groups (experimental and control). Both study groups will receive standard therapy currently available in treatment centers for diabetic foot ulcer (DFU). Associate with the standard therapy, it will be given the recombinant human Epidermal Growth Factor (rhEGF) to experimental group and in the control group, it will be given a formulation without pharmacological effect (placebo) in order to masking and control of intralesional application. Participants with type 1 and type 2 diabetes mellitus (DM) diagnosed with DFU for at least 4 weeks, treated in referral centers participating in the study, agreeing to participate after reading, understanding and signing of Informed Consent (IC); meet all the inclusion criteria; and presenting no exclusion criteria. The Informed Consent (IC) should be applied to potential participants, as recommended by the regulations and ethical consensus before beginning any procedure related to the clinical trial. In the early weeks, participants will be evaluated at the research centers by the study team (doctors and / or staff). The number of visits will be determined by the investigator, thus ensuring appropriate assistance to participants, and avoiding any complications with DFU. By meeting the eligibility requirements (inclusion and exclusion criteria), the participant will undergo a thorough evaluation of the DFU before the start of treatment. This assessment is precisely to classify the condition of the ulcer before treatment and provide relevant information for statistical analysis of the protocol. If eligible, the participant will be randomly set to treatment arm (placebo or rhEGF) and the administration of investigational product associated with predefined standardized outpatient therapy will be initiated. This administration occurs three times per week until the DFU is scarred, not exceeding 8 weeks of treatment (T.01 to T.08) .The study will be randomized and balanced according to the type and size of the DFU. This balancing is necessary to ensure that both treatment groups are homogeneous for participants under different conditions. All participants will be applied established standard therapy for the treatment of DFU. The objective is to provide regular care for healing and reduce possible bias in the efficacy analysis and product safety. After the treatment period (last dose of the experimental drug) the participant will start the follow-up period, with 16 weeks duration. The participant shall be subjected to weekly visits for ongoing assessment of DFU, however, according to the investigator, may result in unscheduled visits to assess local or general clinical events. After the monitoring period, the participant will be observed for 24 additional weeks, visits every 4 weeks (E.01 E.24 a) having beginning one week after the last visit of follow-up. This period is intended to assess possible events related to the efficacy and safety that can happen in the period, mainly for analysis of secondary endpoints.

Conditions

• Foot Ulcer, Diabetic
• Epidermal Growth Factor

Interventions

DRUG

recombinant human Epidermal Growth Factor (rhEGF)

The Heberprot-P® is a parenteral formulation, which is in a lyophilized powder vial presentation containing 75μg of recombinant Epidermal Growth Factor (rhEGF) for local application (intralesional) with the therapeutic potential to promote granulation and wound healing of DFU. The rhEGF is a polypeptide of 53 amino acids and has the ability to stimulate fibroblasts, keratinocytes and vascular endothelial cells proliferation. Then it contributes to its properties in scar tissue formation. The action mechanism is based on the interaction with specific receptors located on specifics cell membranes. The rhEGF was developed through recombinant DNA technology and it has been produced by biotechnological methods in Saccharomyces cerevisiae yeast line.

OTHER

Placebo

This group will receive the standard medication and the placebo drug. The placebo drug has the same formulation, except for the fact that it does not contain the recombinant human Epidermal Growth Factor (rhEGF).
