Clinical Trial Summary

The cannabinoid has benefits in many aspects but the evidence of the effect of cannabinoids in humans with SSc is limited. We, therefore, would like to investigate the efficacy of cannabinoids on the appetite, sleep efficiency, quality of life, pain, and critical cytokine level in SSc compared with placebo in SSc patients and the adverse events associated with cannabinoids in those patients.

Description:

Systemic sclerosis (SSc) is a connective tissue disease for which skin tightness is the hallmark. The disease is classified into 2 major subsets: limited cutaneous systemic sclerosis (lcSSc) and diffuse cutaneous systemic sclerosis (dcSSc) depending on the extent of skin tightness. Not only the skin tightness but also the internal organs such as the musculoskeletal, kidneys, lungs, heart, and intestines can be involved and associated with a poor outcome. Malnutrition and/or weight loss is a complications in SSc. The complication is possibly related to gastrointestinal involvement, inflammation, immunosuppressant agents, or mood disturbance which can affect the food appetite or eating behavior. As well as sleep quality, sleep disturbance has been reported in SSc patients and the associated factor of sleep disturbance in those patients was gastrointestinal involvement, particularly gastroesophageal reflux disease, the severity of pain, and depressed mood. The cannabinoid is an agent which affects appetite, pain, and sleep quality as mentioned above, hence it would improve the appetite, get a high sleep quality and reduce pain associated with musculoskeletal involvement in SSc patients.

Although cannabinoid has benefit in many aspects, they also resulted in serious adverse events after cannabinoid inhalation, including ischemic stroke related to vasospasm of the cerebral vessel, high cardiac output, cardiac arrhythmias, blood pressure fluctuation, and respiratory tract infection. Acute toxicity has been reported and depended on unit dose, tolerance, and route of cannabinoid use. Cannabis also influenced brain function including memory, and cognitive function, and expanded the risk for psychosis in those who had prolonged use. The symptoms of central nervous system (CNS) toxicity include euphoria, panic, agitation, mood alterations, alteration of perception, loss of social inhibition, muscle incoordination, myoclonic jerking, ataxia, slurred speech, and risk of the suicidal idea. In addition, prolonged high doses of cannabis use can lead to the development of cannabinoid hyperemesis syndrome caused by cyclic hyperemesis, finally resulting in electrolyte disturbances and impaired kidney function.

Because the evidence of the effect of cannabinoids in humans with SSc is limited. We, therefore, would like to investigate the efficacy of cannabinoids on the appetite, sleep efficiency, quality of life, pain, and key cytokine level in SSc compared with placebo in SScpatientst and the adverse events associated with cannabinoids in those patients.

• Placebo
The subjects will receive 1 droplet of placebo twice daily then titrate up to 2 droplets twice daily if tolerated and continue the treatment until the end of the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	The changing of sleep quality	The changing of sleep quality evaluated by the Thai Pittsburgh Sleep Quality Index* compare to baseline and a comparison between the treatment group and placebo group; *the score ranges from 0-to 21 and the higher score, the poorer sleep quality	4 weeks
Other	The changing of quality of life	The changing of the quality of life evaluated by EuroQol group 5 dimensions (EQ-5D)* compare to baseline and a comparison between the treatment group and placebo group; *the index composes of 5 dimensions and each dimension includes 3 levels (no problems, some problems, and extreme problems), the higher level of the dimension, the poorer quality of life	4 weeks
Other	The changing pain symptoms	50% decrease of joint pain evaluated by VAS from 0-100* compare to baseline and a comparison between the treatment group and placebo group; *a higher scale, a more pain	4 weeks
Other	The changing of cytokine level (transforming growth factor beta)	The changing of cytokine level compare to baseline and a comparison between the treatment group and placebo group	4 weeks
Primary	The changing of appetite	50% increase of appetite evaluated by a visual analogue scale (VAS) from 0-100* compared to baseline and a comparison between the treatment group and placebo group; *a higher score, a more appetite	4 weeks
Secondary	The changing of serum transferrin level	The mean difference of serum transferrin level compare to baseline and a comparison between the treatment group and placebo group	4 weeks
Secondary	An adverse event	An adverse event	4 weeks
