Efficacy Study of Oral L-Citrulline in Patients Taking Simvastatin With Peripheral Arterial Disease

Peripheral Arterial Disease Clinical Trial

Official title:
Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of Oral L-Citrulline Compared to Placebo in Patients Taking Background Simvastatin 40 mg qD and With Peripheral Arterial Disease Including Intermittent Claudication

Clinical Trial Summary

To prove the combination of L-citrulline with simvastatin leads to greater improvement in the symptoms of peripheral arterial disease (PAD) than simvastatin alone by evaluating oral L- citrulline or placebo against simvastatin for improvement in treadmill walking distance in patients, 40–75 years of age, who have PAD with intermittent claudication.

Clinical Trial Description

The primary objective of this study is to prove the combination of L-citrulline with simvastatin leads to greater improvement in the symptoms of PAD than simvastatin alone. This will be accomplished by evaluating efficacy of orally administered L-citrulline or placebo against background therapy with simvastatin for improvement in treadmill absolute claudication walking distance (ACWD) in patients, 40–75 years of age, who have PAD with intermittent claudication in Fontaine stage II and symptom-limited treadmill walking distance.

Secondary objectives include comparing the combination therapy to simvastatin alone for improvement in treadmill pain-free walking distance (PFWD) and ischemic window.

Other secondary objectives include evaluating the safety and tolerability of L-citrulline alone or combined with simvastatin in this patient population and assessing the effects of treatment on quality of life (QOL) as measured by two QOL instruments. ;
