The feasibility study will be based within a private clinic setting and will only involve existing patients of the clinic. The treatment regime, tests that the patients are required to take, the clinical information they are required to provide, and the informed consent required for treatment, will all follow the clinical protocol. The sponsor wishes to assess the feasibility of conducting the study within the private clinic to aid a future submission to Oxford A REC of the CANPAIN study.~The feasibility study will be conducted over a 3-month period with a minimum target recruitment number of 100 patients. Feasibility will be assessed through 3 distinct domains: Recruitment and patient experience, medication logistics and data management.~Patient experiences (part of domain 3) will be captured using comment forms, requesting feedback on ease of onboarding, ease of answering questionnaires, evidence of questionnaire fatigue and their satisfaction of service.
The CANPAIN study has been devised to evaluate the efficacy and safety of a defined cannabis based medicinal product (CBMP) delivered by inhalation to patients with non cancer chronic pain attending a private clinic. CANPAIN is a pragmatic non-randomised, non-blinded real-world trial of the safety, tolerability and effectiveness of a cannabis based medicinal product (CBMP) for the treatment of chronic non-cancer pain compared against matched controls receiving standard of care pain management. CANPAIN will run for 3 years with a minimal planned sample size of 5000 participants per group who have completed at least 12 months of treatment. CANPAIN will be an MHRA and REC approved study. (See Appendix 1 of the Feasibility Study for the full draft protocol of the CANPAIN Study)~Prior to commencing the CANPAIN study, the sponsor proposes to conduct a feasibility study. This study will aid in establishing likely rates of patient recruitment, duration of participant enrolment in the study, the demographic and geographic spread of patients, patient acceptability of data collection and identify any issues with technological and drug delivery logistics.
