VIRTUOSE : Efficiency of Sildenafil on the Absolute Claudication Distance of Peripheral Arterial Disease Patients With Intermittent Claudication. (VIRTUOSE)
VIRTUOSE : Efficiency of Sildenafil on the Absolute Claudication Distance of Peripheral Arterial Disease Patients With Intermittent Claudication. A Phase III, National, Multicentre, Prospective, Randomised, Double-blind, Placebo-Controlled Trial.
Peripheral Arterial Disease (PAD) is a highly debilitating disease that affects 202 million people around the world and about 7 million people in France. Morbi-mortality from cardiovascular events is increased in this population. Intermittent claudication is defined as a discomfort and/or pain in the legs during walking. It is the most common clinical feature of PAD.
In claudication, primary therapeutic approach is medical treatment and advice to walk. Revascularization is only proposed when medical treatment and advice to walk for at least 3 to 6 months have failed to improve symptoms and walking ability.
Optimal medical treatment includes Antiplatelet, Lipid Lowering Drugs, AT2 antagonists / ACE Inhibitors and advice to walk.
To date, no other drug has provided consistent evidence for functional improvement in claudication, except for Cilostazol, a type-3 phospho-diesterase inhibitor (PDEi). This compound has been scarcely used in France due to cost and frequent side effect (Headache, Flush, Diarrhea, etc.) and was withdrawn as a therapy in 2010.
Sildenafil, a type 5 PDEi, is well tolerated, largely used in impotence and has interesting clinical delay and duration of action in the concept of a potential use in claudication. Preliminary data from the literature and unpublished case reports, suggest that this drug could efficiently improve symptoms and walking capacity in patients with stage 2 claudication.

Detailed Description
Experimental design A Phase III, National, Multicentre, Prospective, Randomised, Double Blind, placebo-controlled clinical trial with two parallel groups.
Eligible patients will be randomised in two groups:
- Experimental group Sildenafil citrate 140 mg/day (single morning oral dose of 140 mg) for a total duration of 24 weeks.
- Control group Placebo (single morning oral dose) for a total duration of 24 weeks.
Treatment will be proposed in addition to optimal treatment (Antiplatelet / Direct Oral Anticoagulant + Lipid Lowering Drugs + AT2 antagonists / ACE Inhibitors; unless contra-indicated) + advice to walk.
The experimental drug will be delivered for a 4 weeks treatment period. Phone contact will be carried out at 7 and 14 days focusing on tolerance, compliance and eventual side effects.
First follow up visit at week 4 will focus on tolerance, compliance and side effects. If no major side effect is found, the study drug will be delivered for an additional 8 weeks.
Phone contact will be carried out at 8 weeks focusing on tolerance, compliance and eventual side effects.
Patients will be evaluated at week 12 (second follow-up visit) for persistent or non-persistent indication for revascularization and considered for revascularization if needed. In parallel, attention will be given to tolerance, compliance and eventual side effects. If no major side effect is found, the study drug will be delivered for an additional 12 weeks period.
Phone contact will be carried out at weeks 16 and 20 focusing on tolerance, compliance and eventual side effects.
Third and fourth follow-up visits are scheduled at week 24 (end of treatment) and week 48 (24 weeks after the end of experimental drugs).
Perspectives
- Improving quality of life of patients suffering a chronic debilitating disease is a major issue not only in vascular medicine.
- It is expected that the treatment may help patients change from a vicious circle (Pain > inactivity > disease progression > pain > increased morbi-mortality) to a virtuous circle (no Pain > improved ability for activity > collateral vessel development > slowing of disease progression > decreased morbi-mortality )
- We expect that half of the patients that fulfil inclusion criteria will be sufficiently improved not to require surgery anymore even 24 weeks after the end of the drug as a result of this virtuous circle.
