Description of intervention(s) / exposure
This observational study will be conducted to observe patients for up to 6 months after receiving cannabis medicines for the treatment of one of four conditions: chronic pain, anxiety, PTSD and MS. The study will be conducted over 2022 and 2023, with recruitment ending at the end of May 2023 and data collection ending at the end of November 2023. The study will collect demographic data including gender, age, as well as medical condition, height/weight/BMI, and current medications at baseline- this is collected via an online form emailed to the participant after signing their informed consent form. This information is automatically uploaded to the study database. Participants will complete online questionnaires at baseline, then 3 months and 6 months. Recruitment for the study will end at the end of May 2023 and the study data collection will end at the end of November 2023. The questionnaires will take approximately 15-20 minutes to complete. Participants complete a questionnaire specific to their condition (ie. for chronic pain, MS, anxiety, PTSD)- there are two questionnaires for MS. Participants also complete questionnaires assessing quality of life, sleep, depression/mood, two questionnaires about side effects and behavioural changes, and a questionnaire about impact of treatment. To assess safety, pathology (blood) tests are conducted at baseline, then at 6 months.

Outcomes
Primary outcome [1] 330272 0
In chronic pain patients: efficacy in alleviating chronic pain is assessed using the Brief Pain Inventory Short Form (BPI-SF), a common validated questionnaire for evaluating chronic pain, including pain severity and interference of pain on feeling and function. For most of the questions, participants tick a box (10 point Likert scale, 0-10) to rate their pain and the impact that their pain has on them.
Timepoint [1] 330272 0
Assessment of chronic pain is conducted at baseline (prior to medicinal cannabis use) then at 3 months and 6 months.
Primary outcome [2] 330273 0
In patients with MS, primary outcome will be efficacy in alleviating chronic pain associated with MS, as measured using the Brief Pain Inventory Short Form (BPI-SF). This is a common validated questionnaire for evaluating chronic pain, including pain severity and interference of pain on feeling and function. For most of the questions, participants tick a box (10 point Likert scale, 0-10) to rate their pain and the impact that their pain has on them.
Timepoint [2] 330273 0
Assessment is conducted at baseline (prior to medicinal cannabis use) then at 3 months and 6 months.
Primary outcome [3] 330274 0
In patients with anxiety as their primary symptom/condition, the primary outcome will be efficacy in reducing anxiety as measured by score on the Generalised Anxiety Disorder 7 (GAD-7), one of the most commonly used, validated self-reported questionnaires used to assess anxiety. This asks patients to rate on a 4 point Likert scale (0,1,2,3) how often they have been bothered by particular problems.

Secondary outcome [1] 405544 0
Quality of life will be assessed using the the Euro Quality of Life 5 Dimensions (EQ-5D). This is a widely used, validated, reliable health-related quality of life tool that measures quality of life through assessment of the severity of each of the five following dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each of these items is assessed on a five-point Likert scale.

Secondary outcome [2] 405545 0
Safety is assessed via conduct of pathology tests (full blood examination, liver function tests and urea and electrolytes). Change from baseline results at 6 months and 12 months for all markers is recorded and assessed.

Secondary outcome [4] 407034 0
Mood/depression is assessed using the Patient Health Questionnaire (PHQ-9), which is a reliable and valid measure of depression severity, that has been validated in general populations, medical populations and psychiatric populations. It is a 9-item self-rating scale that assesses the frequency of depressive symptomatology during the previous two weeks on a four-point Likert scale (0 = not at all; 1 = several days; 2= over half the days; 3=nearly every day). These items are summed to form an overall measure of depressive symptomatology.

Baseline, and 3 months and 6 months after commencing medicinal cannabis.
Secondary outcome [5] 407037 0
Impact of treatment is assessed via the Patients’ Global Impression of Change (PGIC) questionnaire, a validated instrument that assesses impact of treatment. It asks participants to rate impact of treatment on symptoms, activity limitations, quality of life, and emotions on a Likert Scale of 1-7. It also asks participants to circle a number from 0-10 that matches the degree of change since beginning care at the clinic.

The PLC-C is a reliable and validated tool which is widely used to assess self-reported change in PTSD symptoms. It has 15 statements and participants are asked to indicate how much they are bothered by a particular symptom, choosing a response which ranges from not all (0) to extremely (5) (5 point Likert scale).

Statistical methods / analysis
As an exploratory real-world study, the study is intended to provide data about several outcome variables over a 6-month period. The outcomes of this study may also be used to assist in the design of a subsequent larger-scale RCT. It is anticipated that around 500 will be recruited over the recruitment time-period *early 2022 to end of May 2023).
Within each of the four clinical conditions examined in this study, primary endpoints will be the questionnaire scores for each of the condition-specific questionnaires. Secondary endpoints will be the scores from the general questionnaires.

Descriptive statistics will be provided for demographic data (age, height, weight, body mass index).
Data will be aggregated in order to conduct within-groups analyses to assess changes in outcome variables within each of the four conditions, comparing mean outcomes of questionnaire scores with baseline at 3 and 6 months. The data will be checked for normality. Where data is normal, the Paired Student T-test will be used. Where data is non-normal, the non-parametric equivalent of this test, the Wilcoxon Signed Ranks Test will be used. Safety and tolerability data and any changes in blood tests will be reported as frequency data.
Other statistical methods will include analyses of the repeated measures data to examine changes in symptomatology over time, regression-based methods and trajectory-based methods, such as latent trajectory analyses. Such methods allow for the identification of specific symptom trajectories (e.g., gradual reduction in symptoms vs. rapid reduction) and examination of whether individuals following these different trajectories vary on personal characteristics (e.g., gender, symptom intensity at start of treatment) or treatment characteristics (e.g., product type, dose).

Summary
Brief summary
Project Twenty21 Australia is an observational study which will follow patients prescribed medicinal cannabis who have been diagnosed with either chronic pain, anxiety, post-traumatic stress disorder or multiple sclerosis. They will be followed for up to 6 months. The purpose is to investigate whether medicinal cannabis products are efficacious in alleviating the symptoms associated with these conditions, and if they are safe and tolerable.
