Becaplermin Gel for MARTORELL's Hypertensive Leg Ulcers (ERAN)

October 3, 2011 updated by: Assistance Publique - Hôpitaux de Paris

Double Blind Randomized Controlled Trial of Recombinant Human Platelet Derived Growth Factor-BB Gel (Regranex Gel®) Versus Hydrogel (Duoderm Hydrogel®) for Healing of MARTORELL's Hypertensive Leg Ulcers. ERAN Trial.

Background: No medical treatment has proved its efficacy for the treatment of hypertensive leg ulcers in a well designed trial.

Primary aim of the study: to compare the rate of healing in hypertensive leg ulcers treated with becaplermin gel (Regranex Gel®) daily application versus the application of the same quantity of an hydrogel (Duoderm Hydrogel™), corresponding to the excipient of becaplermin gel.

Method: Ambulatory or hospitalized patients presenting with an hypertensive leg ulcer, were randomized to receive either a daily application of becaplermin gel or hydrogel during 8 weeks. At week 8, a pinch graft was proposed to patients whom the ulcer has not healed.

Primary aim of the study: Complete closure at week 8

Secondary aims: percentage of wound area reduction at week 8, complete closure at week 12, pain and quality of life during treatment

Study hypothesis: becaplermin gel may promote the healing of hypertensive leg ulcers and be an alternative medical treatment to the skin graft usually proposed

Detailed Description

Hypertensive leg ulcers are a variety of leg ulcer characterized by very painful and spreading lesions, related to cutaneous microangiopathy, occurring in patients presenting hypertension and /or diabetes. Healing takes a mean of 4 to 12 months. Current treatment is difficult and usually surgical (pinch or meshed skin grafts). Growth factors release by autografted skin may be a significant factor in the promotion of hypertensive leg ulcer healing. Recombinant human platelet derived growth-factor-BB gel (becaplermin gel) has been shown to be effective in the treatment of diabetic ulcers related to diabetic microangiopathy. The objective of the study was to assess the efficacy of becaplermin gel for the healing of hypertensive leg ulcers. Study design: prospective, randomized, multi-centre, double blind, controlled, parallel groupPrimary aim: complete wound closure at week 8Secondary aims: complete wound closure at week 12, pain and quality of life assessment during the treatment( W4,8,10,12), % of wound area reduction at week 8 and 12 Method: Inclusion of 64 patients, 32 in each group. The study population consisted of consecutive patients presenting with one or more leg ulcers diagnosed as hypertensive MARTORELL's ulcers: hypertensive and/or diabetic patients, in absence of chronic venous insufficiency (C5-C6 of the CEAP) or peripheral arterial occlusive disease (presence of peripheral pulses or ankle brachial index ≥0.8), superficial spreading necrotic ulcer, presence of spontaneous pain, and presence of a red purpuric margin. Treatment consists of a daily application of a continuous thin layer of becaplermin gel (Regranex Gel®) or Duoderm Hydrogel™, during 8 weeks. The amount of the gel to be applied was determined based on ulcer area at inclusion (as recommended for Regranex gel®), and remains identical during all the treatment. Wound was then recovered by a moist saline gauze and a bandage. Duoderm Hydrogel™ is a sodium carboxymethylcellulose aqueous-based gel, similar in composition to becaplermin excipient.At week 8, a pinch graft was proposed to patients whom the ulcer was not healed. Between weeks 8 and 12, if patient had not healed and was not grafted, dressing was chosen by the investigator, depending on the wound stage. All patients were followed until week 12.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: becaplermin gel
application of a continuous thin layer of becaplermin gel (Regranex Gel®) during 8 weeks. The amount of the gel to be applied was determined based on ulcer area at inclusion, and remains identical during all the treatment.
Drug: becaplermin gel
the amount of the gel to be applied was determined based on ulcer area at inclusion and remains identical during all the treatment The posology was identical to what is recommended for Regranex gel®: a single 15g-tube is enough to treat a 5 cm2-wound during 6 weeks (1 cm of gel is applied daily for 5 cm2) Wound was then recovered by a moist saline gauze and a bandage. Becaplermin gel is packaged into masked 15g-tubes.
Active Comparator: Duoderm Hydrogel™
application of a continuous thin layer of hydrogel dressing (Duoderm Hydrogel®), during 8 weeks. Duoderm Hydrogel™ is a sodium carboxymethylcellulose aqueous-based gel, similar in composition to becaplermin excipient.
