Clinical Trial Summary

Digital ulcers (DUs) are an expression of the microangiopathy in patients with scleroderma (SSc). DUs lead to pain and impaired hand use. DUs remain a severe complication for many patients and effective therapy remains elusive. In the present study, the investigators propose to evaluate the efficacy of Sildenafil in DUs healing in a randomized double blind control study in SSc patients.

Description:

This is a multicenter, prospective, longitudinal, randomized, comparative, double-blind, 2-parallel-arm, placebo-controlled study aimed to evaluate the efficacy of sildenafil 20 mg TID study on time to healing of DUs in SSc patients with ischaemic DUs.

Approximately 120 patients aged from 18 years and above will be allocated to receive either placebo or sildenafil 20mg TID during 90 days. All potential subjects will present with ischaemic digital ulcers complicating scleroderma. An eligible digital ulcer must be beyond the proximal interphalangeal joint, on finger surface (included periungual ulcers), of ischemic origin according to the physician, and not over subcutaneous calcifications or bone relief.

• Patient with a history of upper extremity deep vein thrombosis or lymphedema within the previous 3 months.

• Patient participating in a clinical trial or having participated in a clinical trial within the previous 3 months.

• Patient having received a treatment with sildenafil for digital ulcers or pulmonary arterial hypertension within 3 months prior to inclusion.

• Patient having received a treatment with parenteral prostanoids (prostaglandin E, epoprostenol, treprostinil sodium or other prostacyclin analogs) within 3 months prior to inclusion.

• Patient having received a treatment with inhaled or oral prostanoids one month prior to inclusion.

• Patient with previous intolerance or allergy to PDE5 inhibitors or a history of multiple clinically significant allergies.

• Pregnant or lactating female.

• Patient with hemodynamic instability or systolic arterial pressure less than 90 mmHg and/or symptomatic orthostatic hypotension.

• Patient receiving all forms of prostacyclin or nitrates or nitric oxide donors in any form including Nicorandil.

• Patient receiving potent inhibitors of CYP3A4 such as ketoconazole, itraconazole, ritonavir.

• Patient with any condition that prevents compliance with the protocol or adhering to therapy.

• Patient who has donated blood during the previous month or intends to donate blood or blood products during the study or for one month following completion of the study.

• Patient under guardianship (including curators) or deprived of liberty.

• Patient presenting with an anatomic malformation of penis (such as an angulation, sclerosis of erectile tissue or "Lapeyronie's disease").

• Patient presenting with a disease which predisposes to priapism (such as sickle-cell disease, myeloma or leukemia).

• Patient presenting with at least one digital ulcer meeting the exclusion criteria (see below).

• Relative to each DU:

• Digital ulcer due to conditions other than scleroderma.

• Non ischaemic digital ulcer.

• Infected digital ulcer requiring systemic antibiotherapy.

• Digital ulcer requiring urgent surgery.
