Topical Cannabidiol for Treating Carpal Tunnel Syndrome

Официальное название

A Randomized Controlled Trial of Topical Cannabidiol for the Treatment of Carpal Tunnel Syndrome

Обзор

The Purpose of this study is to assess the safety and efficacy of Cannabidiol on treatment of Carpal Tunnel Syndrome.

Подробное описание

Carpal tunnel syndrome (CTS), or compression neuropathy of the median nerve at the wrist, is the most common entrapment neuropathy affecting up to 15% of the general population Non-operative interventions for CTS include night-time splinting, physical therapy, and corticosteroid administration, however only surgery is considered a definitive treatment for CTS. There is an unmet need for novel, effective non-operative options for the treatment of CTS to provide care for patients who cannot undergo surgery for medical reasons or do not feel comfortable proceeding with a surgical option.

Cannabidiol (CBD) is a non-psychoactive minor cannabinoid component of Cannabis sativa that is emerging as a treatment to mitigate pain, numbness, and tingling associated with peripheral neuropathy. Pre-clinical data indicates that CBD acts through multiple receptors to modulate central and peripheral neuropathic signaling pathways to alleviate pain - specifically in pre-clinical models of compression neuropathy as in CTS. This pilot trial seeks to investigate whether CBD is a safe, feasible, and effective treatment for CTS in patients with confirmed mild to moderate CTS receiving standardized physiotherapy with primary endpoints assessing feasibility, symptom severity, and/or disability and also highlights the gap in knowledge regarding the clinical utility of cannabinoids

Первичные конечные точки

• Feasibility of CBD as a topical treatment for CTS is determined by the investigator by evaluating the Recruitment Rate, medication compliance rate and retention rate. [Срок оценки: 2 weeks and then crossover to other cream for 2 more weeks after a 1 week washout period.]

Вторичные конечные точки (7)

• The efficacy of CBD as a topical treatment for carpal tunnel syndrome is measured by a. Change in symptom severity as reported with the Boston Carpal Tunnel Symptom Severity Scale from baseline and study Days 14, 21 and 28. [Срок оценки: 2 weeks]
• The efficacy of CBD as a topical treatment for carpal tunnel syndrome is measured by change in patient reported outcomes measured by SANE scores from baseline and study Days 14, 21 and 28. [Срок оценки: 2 weeks]
• The efficacy of CBD as a topical treatment for carpal tunnel syndrome is measured by change in Patient reported outcomes measurement information system from baseline and study Days 14, 21 and 28. [Срок оценки: 2 weeks]
• The efficacy of CBD as a topical treatment for carpal tunnel syndrome is measured by change in VAS scores from baseline and study Days 14, 21 and 28. [Срок оценки: 2 weeks]
• Along with efficacy, safety of CBD is measured by performing set of Laboratory tests [Срок оценки: 2 weeks]
• Safety of CBD is measured by collecting relevant Medical History as a part of safety assessment. [Срок оценки: 2 weeks]
• Safety of CBD is measured by performing skin monitoring tests and physical examination. [Срок оценки: 2 weeks]
