Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The treatment product is a topical 4% w/w Cannabidiol gel that is applied 3 times per day over a four week period to joints of the hand suffering painful arthritis. The product is supplied in a metered pump that administers 0.25 ml. Subjects will be instructed to apply a single 0.25 ml pump to the affected hand at each application. The gel will then be massaged into the joints of the hand affected by arthritis.

Subjects will complete a questionnaire each night via their smart-phone, that will ask them to confirm that they have adhered to the application instructions that day as described by the protocol.

Outcomes
Primary outcome [1] 328892 0
Changes in hand pain as assessed by the Numeric Pain Rating Scale (NPRS)
Timepoint [1] 328892 0
Pain scores will be recorded on a daily basis during week 1 to calculate baseline pain scores. Pain scores will be recorded on a daily basis from weeks 2-5 to accompany the 4 week dosing period. The primary outcome will compare pain scores 4 weeks post commencement with those obtained at baseline to determine whether the treatment has had any effect..
Secondary outcome [1] 400812 0
Changes in grip strength as assessed by a squeeze ball dynamometer connected via Bluetooth to a recording app
Timepoint [1] 400812 0
Grip strength will be recorded on a daily basis during week 1 to calculate baseline scores. Grip strength will be recorded on a daily basis from weeks 2-5 to accompany the 4 week dosing period. The secondary outcome will compare grip strength scores 4 weeks post commencement with those obtained at baseline to determine whether the treatment has had any effect..
Secondary outcome [2] 401565 0
Changes in hand functionality as measured by the Functional Index for Hand OsteoArthritis (FIHOA) score.
Timepoint [2] 401565 0
FIHOA scores will be recorded on a weekly basis. FIHOA scores at 4 weeks will be compared with those recorded at Baseline..

Summary
Brief summary
This study will assess whether topical application of a CBD gel can provide analgesia for patients suffering from osteoarthritis of the hand.

A growing body of evidence suggests that inflamed tissue caused by osteoarthritis may be susceptible to treatment using CBD. Despite oral ingestion of cannabinoid products being the preferred route of administration, its poor aqueous solubility and extensive first-pass metabolism lead to poor bioavailability, which limits see its potential efficacy. The ability to deliver CBD directly to local, inflamed tissue using topical application may provide superior analgesia than oral dosage forms, whilst minimising any concerns related to systemic exposure.

This study will assess whether topical application of a CBD gel can provide analgesia for patients suffering from osteoarthritis of the hand. In addition to analgesia, the study will investigate whether topical CBD can provide benefits for other symptoms of osteoarthritis of the hand; poor grip strength and hand functionality. Results from this study will support further clinical development of the CBD gel, as well as future prescribing to patients.
