What this trial studies

This study evaluates the effectiveness of Botulinum toxin (BT) in treating patients with Raynaud's Phenomenon (RP) that is resistant to standard medical therapies. It involves a single-site, double-blinded, randomized, placebo-controlled design where participants will receive either BT injections at two different doses or a saline control. The study aims to measure both objective and subjective outcomes related to pain, blood flow, and tissue health in the fingers. The goal is to provide a new treatment option for patients suffering from severe RP.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 or older with moderate to severe Raynaud's Phenomenon that has not responded to standard medical therapy.

Not a fit: Patients who have undergone previous Botulinum toxin treatment for Raynaud's Phenomenon within the past year or those with active infections at the treatment site may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients with refractory Raynaud's Phenomenon by reducing pain and preventing tissue loss.

How similar studies have performed: Previous studies have shown promising results for the use of Botulinum toxin in treating Raynaud's Phenomenon, although this specific approach is still being evaluated.
