Can-Art Effect and safety of using Canabis derivatives for the treatment of pain in patients with inflammatory Arthritis, such as reumatoid arthritis and ankylosing spondylitis, the latter being a type of arthritis that causes a long term inflammation of the joints of the spine. A randomized, double blinded, placebo controlled trial, i.e. in this drug trial, a control group is given a placebo while another group is given the Cannabis derivative being studied.

CAN-ART The efficacy and safety of using cannabis derivatives cannabidiol (CBD) and tetrahydrocannabinol (THC) for the treatment of pain in patients with inflammatory arthritis (RA, AS). A randomized, double blinded, placebo controlled trial - Can-Art

Design outcomes

Primary

MeasureTime frame
Secondary Objective: A significantly improved pain situation as assessed by the number of AS patients that achieve a Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) 20 after 12 and/ or 24 weeks of treatment with CBD or 12 weeks of treatment with CBD followed 12 weeks of treatment with the combination of CBD and THC in an open follow-up. A significantly improved life situation as assessed by the number of patients that achieve a Global VAS 20 after 12 and/ or 24 weeks of treatment with CBD or 12 weeks of treatment with CBD followed by 12 weeks of treatment with a combination of CBD and THC in an open follow-up study. The effect of the intervention on the patients attention and concentration is investigated using cognitive tests (Trail Making Test (TMT) and Digit Symbol Substitution Test (DSST)). Additionally, sleep quality is evaluated with the Pitssburgh Sleep Quality Index.;Primary end point(s): The study investigates the effect of CBD, more specific whether the add-on treatment with CBD results in a significantly improved pain situation as assessed by the number of patients achieving an improvement of pain-VAS with a reduction of ? VAS> 20. Assessment takes place after 12 and 24 weeks of active treatment with CBD. B. If the patient does not experience an acceptable effect of the CBD treatment in the assessment after 12 weeks (as defined by study protocol, i.e. pain VAS reduction > 20), the randomization is terminated and the treatment proceeds by a combination of CBD and THC. THC 2.5 mg daily in week 13 and 14, increasing to 5 mg (2.5 mg x 2 daily) in the following two weeks. If no effect has occurred after week 16, the dose increases in the beginning of the 17th week to the maximum of 7.5 mg THC (2.5 mg x 3 daily) in the 3rd week 2. Thus, the study investigates the effect of the combination of CBD and THC, more specific whether the add-on treatment with CBD for 12 weeks followed by the combined treatment of CBD and THC for another 12 weeks r

Secondary

MeasureTime frame
Secondary end point(s): Secondary outcomes 1) Outcomes: Clinical measurements, i.e. in RA the Disease Activity Score 28-joints (DAS28-CRP), Health Assessment Questionnaire (HAQ) and in the case of AS the Ankylosing spondylitis disease Activity Score (ASDAS) and Bath Ankylosing Spondylitis (BAS)-scores for disease activity (BASDAI), function (BASFI) and measures (BASMI) are registered . Patient Reported Outcome Measures (PROMs) more specific, visual analogue scales (VAS) for fatigue, patient’s global; the Quality of Life (QoL) - and pain- scores SF-36 and PainDETECT are obtained. Furthermore, the effect of intervention on attention and concentration is investigated using the following cognitive test: Trail Making Test (TMT) and Digit Symbol Substitution Test (DSST). Additionally, sleep quality is evaluated with the Pitssburgh Sleep Quality Index and the expected effect for treatment is measured with Credibility/expectancy Questionnare Devilly and semistructured course interviews. Thus, the study investigates the effect of CBD, more specific whether the add-on treatment with CBD results in a significantly improved fatigue situation and as well more holistic qulaity of life situation as assessed by the number of patients achieving an improvement of fatigue-VAS with a reduction of ? VAS> 20 and an improvement of global-VAS with a reduction of ? VAS> 20. Assessment takes place after 12 and 24 weeks of active treatment with CBD. Furthermore, the study investigates the effect of the combination of CBD and THC, more specific whether the add-on treatment with CBD for 12 weeks followed by the combined treatment of CBD and THC for another 12 weeks results in a significantly improved fatigue situation and as well more holistic qulaity of life situation as assessed by the number of patients achieving an improvement of fatigue-VAS with a reduction of ? VAS> 20 and an improvement of global-VAS with a reduction of ? VAS> 20. 2) Exposures, i.e. current treatments with DMAR
