The following amendments have been made to the original version of the protocol (dated 7 October, 
2020).  
 
Version 1.1 (25 November 2020)  
• 
On the title page of the protocol we included the legal entity 11318152 Canada Inc. This was a request from the 
Study Insurance Broker.  
•    Appendix 6 Classification of Chronic Pain IASP ICD 11 was developed to further illustrate Subject Inclusion 
Criteria. The definition of Subject Inclusion Criteria 1. was changed from “Subject ≥ 25 years of age with a 
diagnosis of chronic non-cancer pain defined as pain lasting or recurring over a period > 3 months (IASP-ICD-11 
classification)” to “Subject ≥ 25 years of age with a diagnosis of chronic non-cancer pain defined as pain lasting 
or recurring over a period > 3 months (IASP-ICD-11 classification, refer to Appendix 6)”. Changes were made in 
several places in the protocol to reflect this change, including in the table of contents (p. 5), the Synopsis (p. 10), 
Section 6.1 (Subject Inclusion Criteria p. 21), and Appendix 6 (p. 79).  
• 
The ST Discontinuation and Exit Assessment are now two separate assessments. Changes were made in several 
places in the protocol to reflect this change including in the table of contents (p. 5), the Synopsis (p. 9), in Table 
1. (Schedule of Events p. 12), Section 3.1. (Study Design p. 17), in Appendix 4 (ST Discontinuation p. 76) and in 
Appendix 5 (Exit Assessment p. 78).

Title of Study 
Global Registry for the Use of Spectrum Therapeutics Cannabis Products in 
Subjects with Chronic Pain 
Number of sites: 
Estimated 50-150 sites 
Study Population: Adults ≥ 25 years of age with chronic non-cancer pain 
Purpose and Study Rationale 
Chronic pain affects at least 10% of the global population but is often poorly managed, given the variable 
efficacy of available pharmacological treatments and the limited accessibility of multidisciplinary 
interventions. The legalization of cannabis in at least 14 countries and the increasing regulatory approval 
of cannabis preparations and synthetic cannabinoids and analogues have led to a growing interest in the 
use of medical cannabis products to manage chronic pain. This use is supported by research 
demonstrating important interactions between cannabinoids and the human endocannabinoid system and 
pain modulation pathways. While medical cannabis products are increasingly available to practitioners 
who treat pain, there is little evidence-based guidance for prescribing or titrating these treatments to 
manage chronic non-cancer pain. This prospective registry aims to assemble real-world data regarding 
the use of Spectrum Therapeutics (ST) medical cannabis products in subjects with chronic non-cancer 
pain in countries where these products are commercially available. The registry will also assess 
treatment outcomes, including pain and related symptoms, global impressions of improvement, and 
change in concomitant pain medications (opioid use in particular), to better inform the utility of ST 
products for chronic non-cancer pain management.

Study Design 
The present study is a prospective, observational registry designed to generate real-world data on the 
physician-recommended use of ST products for the management of chronic non-cancer pain in countries 
where these products are commercially available. The study will enroll 1500 subjects from 50-150 sites 
in geographic regions of ST product distribution, over a 2-year period. Subjects at each site will be 
followed for one year to collect data on demographics, chronic pain classification, cannabis experience, 
treatment goals, concomitant medication(s), ST treatment regimen, clinical assessment, subject-reported 
outcomes, and safety. 
The study includes five physician-verified visits (baseline, 2, 4, 8, and 12 months), and four at-home 
subject-verified follow-ups (months 1, 3, 6, 10). Physician verified follow-ups can be conducted in 
person or via telemedicine. Additionally, should there be a need, according to the physician’s judgement, 
there may be other unscheduled visits, either in-clinic, or via telemedicine. 
All data will be collected using REDCap Cloud data management platform, via online electronic case 
report forms (eCRFs), and questionnaires. During physician-verified visits, online questionnaires will 
be completed by both the physician and the subject (in the presence of a physician or study site 
personnel). At-home subject-verified follow-ups will be conducted via the REDCap Cloud online portal 
accessible by computer, tablet, or smartphone. 
The following activities will be completed at the Baseline Visit. 
• 
The subject will receive an explanation of the study purpose and procedures, sign the electronic 
informed consent form (eICF), physician will review eligibility check list, if female of child- 
bearing potential, subject will complete a urine pregnancy test. 
• 
Together, physician and subject will create an account on REDCap Cloud. 
• 
Together, physician and subject will complete the baseline assessment measuring: 
o Demographics; 
o Chronic pain classification; 
o Cannabis experience; 
o Concomitant medications; 
o Treatment goal; 
o ST treatment regimen; 
o Brief Pain Inventory-Short Form (BPI-SF); 
o Euro Quality of Life Assessment (EQ5D-5L). 
• 
The subject will be scheduled for the first physician-verified follow-up visit approximately 2 
months after the initiation of treatment with an ST product. 
The following activities will be completed at each physician-verified follow-up visit: 
• 
Physician and subject will discuss the overall treatment regimen. 
• 
Physician will review the subject’s online REDCap Cloud entries. 
• 
Together, physician and subject will complete the follow-up visit assessment measuring: 
o ST treatment regimen 
o Concomitant medications 
o Clinician Global Impression of Improvement (CGI-I) 
o BPI-SF 
o EQ5D-5L 
o Patient Global Impression of Change (PGI-C) 
o Physician adverse events (AEs) form

The following measures are to be completed by the subject for each at-home follow-up: 
o ST treatment regimen 
o Additional cannabis consumption 
o BPI-SF 
o EQ5D-5L 
o Patient Global Impression of Change (PGI-C) 
o Subject adverse events (AEs) log 
In the event of ST treatment discontinuation or study dropout, physicians will be asked to attempt to 
follow-up with subjects for the completion of the ST Discontinuation assessment and  Exit assessment. 
Based on physician answers to the ST Discontinuation Assessment, subjects will either stay enrolled in 
the study (e.g., discontinue all cannabis treatment, but continue to be monitor by site physician for 
chronic pain), or be withdrawn (e.g., unwilling to stay in the study, switched cannabis licensed producer). 
A complete schedule of events is provided in Table 1. 
Safety Monitoring: 
Spontaneous AE reporting will be entered in REDCap Cloud by the subject during subject follow-ups, 
using the Subject AE log. Physicians will verify and assess all AEs entered at physician follow-ups, 
using the Physician AEs form. All serious adverse events will be sent directly to Canopy Growth’s 
Global Pharmacovigilance Department (GPVD) in real-time, where they will be reviewed with respect 
to country specific regulatory requirements. All non-serious adverse events will be sent in a monthly 
report to GPVD. 
Outcome Assessments: 
• 
The BPI-SF is a 9-item self-report questionnaire that includes 6 pain items (e.g., location, 24- 
hour worst pain, 24-hour average pain, pain right now); 2 treatment items; and 1 (7 part) pain 
interference item. 
• 
EQ5D-5L is a 5-category questionnaire (total of 6 questions) assessing mobility, self-care, usual 
activities, pain/discomfort, anxiety/depression, and overall health on a scale from 0-100 (where 
100 denotes the best, and 0 the worst health). 
• 
The PGI-C is a 1-item self-report outcome question that measures a subject's overall impression 
of improvement during treatment using a 7-point Likert-type scale. The PGI-C shows good 
performance in subjects with chronic pain and is often more responsive than primary measures 
of pain intensity. 
• 
The CGI-I is a 1-item clinician-reported outcome question, similar to the PGI-C, that measures 
a clinician’s overall impression of subject improvement in response to treatment using a 7-point 
Likert-type scale. The CGI-I typically correlates well with the PGI-C. 
Duration of Subject Participation and Treatment: Subjects will be followed for one year, unless the 
subject withdraws early, either independently or in response to physician recommendation. ST treatment 
will continue for as long as subjects and physicians agree that there is a benefit and treatment is tolerated.

The Sponsor will perform statistical analyses. The Sponsor or designee will extract and analyze 
descriptive data every 6 months. This will be done to keep sites apprised of study progress. A de- 
identified summary report will be generated and delivered to all registered site physicians. 
The report will indicate: 
• 
The number of physician-collaborators stratified by country. 
• 
The number of subjects enrolled stratified by country. 
• 
Subject demographics, chronic pain classification, and treatment goal. 
• 
Subject concomitant medication use. 
• 
Subject ST treatment regimens. 
• 
Incidence of AEs per individual ST product. 
Upon database lock a series of analysis will be conducted to address study objectives. For each analysis, 
the normality of the data distributions will be ascertained using the Shapiro-Wilk test of normality and 
Levene’s test of equality of error variance. Descriptive statistics (frequencies, means, and standard 
deviations for normally distributed parametric data; medians and interquartile ranges for nonparametric 
data) will be used to characterize the sample. Outcome analyses will include a change in ST regimen; a 
change in reported opioid consumption in MME/day; change in daily dose of other medications, 
including analgesics, sedatives, and benzodiazepines; change in responses to BPI-SF items and EQ-5DL 
items; initial PGI-C and changes over time; and initial CGI-I and changes over time. For the safety 
endpoint, AEs will be tabulated descriptively. Detailed analyses are outlined in the Statistical Analysis 
Plan. 
Number of Subjects (Planned): 
Given a continuous enrollment design, the study will include two enrollment milestones over the 2-year 
study period. Milestone 1, targeted for the end of year 1 will be to recruit 750 subjects. Milestone 2, 
targeted for the end of year 2 will be to recruit 750 subjects. To enroll a total of up to 1500 subjects. The 
number of subjects may vary based on the real-life use of ST products. Sites will be recruited from 
countries where ST products are available: Canada, United Kingdom, Germany, and Australia. Sites 
from additional countries may be included as ST products are rolled out in those countries and based on 
site feasibility. 
The present study has an observational design that poses low-burden for subjects, as the number and 
frequency of in-clinic (telemedicine) visits represent those necessary for adequate monitoring of 
treatment for chronic pain and at-home follow-ups will be completed using a simple online app and take 
no longer than 15 minutes to complete. On this premise, we did not restrict the sample size based on an 
estimated minimum required sample. Furthermore, the observational nature of the primary endpoint 
(daily average dose [in mg] of THC and CBD and mode of administration [inhaled or ingested]), did not 
permit an a priori power analysis to estimate sample size. A sample size of 1500 subjects is consistent 
with similar previous observational registry studies.

BACKGROUND INFORMATION AND STUDY RATIONALE 
 
1.1 
Background 
Chronic pain, defined by the International Association of Pain (IASP) as pain persisting or recurring for 
more than three months, refers to a complex and heterogeneous group of disorders that produce significant 
disability and emotional distress.1–5 Studies suggest that chronic pain affects at least 10% of the worldwide 
population, with estimates approaching 20–25% in some regions6. 
According to IASP27, chronic pain is the “parent code” for 7 other codes that compromise the most common 
clinically relevant groups of chronic pain conditions (Top-level diagnosis): (1) chronic primary pain; (2) 
chronic cancer-related pain; (3) chronic post-surgical or post-traumatic pain; (4) chronic neuropathic pain; 
(5) chronic secondary headache or orofacial pain; (6) chronic secondary visceral pain; and (7) chronic 
secondary musculoskeletal pain. Within the primary pain syndrome, pain is conceived as a disease or health 
condition, whereas in secondary pain syndromes, pain is regarded as a symptom. 
Given the limited access to physical and psychological interventions for chronic pain7–9 and the variable 
efficacy and tolerability of currently available medications10,11, there is a growing interest in the use of 
cannabinoids (medical cannabis and cannabis-based medicines) for chronic pain management. The 
legalization of cannabis in at least 14 countries and regulatory approval of cannabis extract preparations, as 
well as the emergence of synthetic cannabinoids and analogs, is expected to herald an increase in the number 
of individuals seeking cannabinoids as a means of pain relief. A recent European Pain Federation position 
paper provided a series of recommendations surrounding cannabis-based medicines to this effect12. 
Cannabis has a long history of therapeutic use for pain and other indications. Research into the 
pharmacology of cannabinoids and their mechanisms of action13 has led to the identification of an 
endocannabinoid system (ECS) in humans, composed of endogenous cannabinoids, the proteins responsible 
for their synthesis, release and degradation, their associated metabolites, and cannabinoid receptors14. Of 
more than 120 cannabis-derived phytocannabinoids, the majority of cannabis’ effects are attributed to two 
compounds: delta-9-tetrahydrocannabinol (THC), the main psychoactive cannabinoid in cannabis, and 
cannabidiol (CBD), a non-euphoric cannabinoid that has been investigated in pre-clinical studies for effects 
on anxiety, cognition, inflammation, and pain15,16. Both THC and CBD have been demonstrated to bind and 
modulate various receptors within the ECS to mediate their proposed therapeutic effects. 
Despite accumulating experimental and clinical evidence both for and against the use of cannabis products 
in subjects with chronic pain, there are limited guidelines or standards of care to facilitate the safe and 
effective prescription of cannabinoid formulations by physicians who treat subjects with chronic pain. This 
study aims to establish a Spectrum Therapeutics (ST) Chronic Pain Registry that will collect descriptive, 
clinical, and outcome data on the use of ST medical cannabis products in subjects with chronic pain. These 
real-world data will provide insights regarding physician-recommended treatment regimens, titration, 
safety, and changes in self-reported pain relief, daily function, and quality of life. Additionally, data 
generated from the registry will aid in the development of further controlled clinical studies, market access 
initiatives, educational programs, and future publications. 
 
1.2 
Rationale 
Primary chronic pain and chronic musculoskeletal pain are the most common reasons people cite for using 
medical cannabis products 13, 17-20. Rapid changes in the global regulatory landscape regarding medical use 
of cannabis and cannabinoids have had a significant impact on health care professionals who currently 
receive little or no education on medical cannabis19. Appropriate knowledge about the use of medical 
cannabis and evidence to support the development of clinical guidelines is essential for the effective use of 
medical cannabis by health care professionals. This sentiment parallels requests for the development of 
research in this area by professionals and the media 20, 21.

STUDY DESIGN 
 
3.1 
Description of the Study 
The present study is a prospective, observational registry designed to generate real-world data on the 
physician-recommended use of ST products to manage chronic pain in countries where these products are 
commercially available. The study will enroll up to 1500 subjects from 50-150 sites in geographic regions 
of ST product distribution over a two-year period. Physicians will recruit subjects during routine care visits 
and assess whether subjects with chronic pain are candidates for medical cannabis treatment. Once enrolled, 
subjects will be followed for 1 year to collect data on demographics, chronic pain classification, cannabis 
experience, treatment goals, concomitant medication(s), ST treatment regimen, clinical assessment, subject-
reported outcomes, and safety. 
The study includes five physician-verified visits (baseline, 2, 4, 8, and 12 months), and four at-home 
subject-verified follow-ups (months 1, 3, 6, 10). Physician verified follow ups can be conducted in person 
or via telemedicine. Additionally, should there be a need, according to the physician’s judgement, there 
may be other unscheduled visits, either in-clinic, or via telemedicine. All data will be collected using 
REDCap Cloud via online eCRFs. The study time-points were selected based on the typical timeframe of 
titration in routine care, and adverse event (AE) emergence for the use of cannabis products in new subjects; 
a majority of titration occurs within the first month of taking a new cannabis product29. Visits were also 
spaced out so that subject retention may be maximized, and treatment adjusted in a timely manner. Later 
time-points are designed to capture longer-term treatment-related outcomes while screening for AE 
emergence and medication use changes in the long term. 
At the first visit (Day 1), subjects will complete the informed consent. A pregnancy test will be administered 
to women of childbearing potential, and the site physician or study site personnel will confirm subject 
eligibility criteria. Following this, the site physician or study site personnel trained in the use of REDCap 
Cloud will assist each subject in creating a REDCap Cloud account and completing the baseline assessment 
(Appendix 1). The first visit (Day 1) will assess important baseline information, including demographics, 
chronic pain classification, cannabis experience, concomitant medications, treatment goal, and ST treatment 
regimen. Subjects will complete the Brief Pain Inventory-Short Form (BPI-SF) and Euro- Quality of life 
Assessment (EQ5DL) at this visit. 
At each subsequent physician-verified visit (a total of 4), the site physician or study site personnel will 
assist with the completion of physician follow-up assessment (Appendix 2) via REDCap Cloud, and 
reassess ST treatment regimen, concomitant medications, effectiveness and tolerability of the ST treatment 
regimen (including AEs & SAEs). Subjects will complete the BPI-SF, EQ5DL, and Patient Global 
Impression of Change (PGI-C) and physicians will complete the Clinical Global Impression-Improvement 
(CGI-I). 
Four subject-verified follow-up assessments will be completed by subjects via the REDCap Cloud online 
portal (Appendix 3). Subjects will receive an automated email one week prior and the day of subject- 
verified follow-up with a reminder to complete the online assessment. The subject-verified online 
assessment will include questions about their ST treatment regimen, additional cannabis consumption, 
numeric rating scale (NRS) pain items of the BPI-SF, the EQ5D-5L, and the PGI-C. 
Spontaneous AE reporting will be entered in REDCap Cloud by the subject during subject follow-up 
assessments, using the Subject AE log (Appendix 3). Physicians will verify and assess all AEs entered at 
physician follow-ups, using the Physician AE form (Appendix 2). All serious adverse events will be sent 
directly to Canopy Growth’s Global Pharmacovigilance Department (GPVD) in real-time, where they will 
be reviewed with respect to country specific regulatory requirements. All non-serious adverse events will 
be sent in a monthly report to GPVD.

In the event of ST treatment discontinuation, or study dropout, physicians will be asked to follow-up with 
subjects to complete the ST Discontinuation Assessment and  Exit assessment (Appendix 4). Based on 
physician answers to ST Discontinuation Assessment , subjects will either stay enrolled in the study (e.g., 
discontinue all cannabis treatment, but continue to be monitored by site physician for chronic pain), or be 
withdrawn (e.g., unwilling to stay in the study, switched cannabis licensed producer). 
A complete schedule of events is provided in Table 1.

STUDY MEDICATION 
For the purposes of this study, subjects enrolled will have been prescribed/authorized Spectrum 
Therapeutics products that are commercially available in participating countries. It is important to note that 
product availability varies from country to country. No country except Canada, has access to the full ST 
medical portfolio (e.g., only flowers are available in Germany). 
The full repertoire of Spectrum Therapeutics products is outlined here (see Figure 1). It encompasses six 
“colors” (order from Red to Yellow follows the descending THC:CBD ratio), and five types of 
formulations: soft gels, spray*, oil, flowers and vapes). Refer to webpage for the most up to date products 
available per country https://www.spectrumtherapeutics.com/canada/en/patients/products. 
Figure 1. Repertoire of Spectrum Therapeutics Products. 
 
*Spray formulation is the most recent addition to the formulations and not yet featured on the web site. 
 
4.1 
Study Medication Prescribing/Authorization 
Medical cannabis is accessible to subjects via different authorization or prescription pathways, in different 
regional jurisdictions. Authorization and prescription are the two most common pathways. 
In Canada, Spectrum Therapeutics products are authorized via the physician specifying the amount (in 
grams) of THC and/or CBD, and the subject is free to choose the product, licensed producer, and 
formulation on their own. Likewise, subjects have the freedom to switch from one product or producer to 
another, at will. 
In other countries, such as Germany, medical cannabis products are prescribed, and physicians are specific 
in this process regarding parameters such as the licensed producer, mode of administration, and cannabinoid 
content (THC:CBD). 
This protocol does not assign a specific intervention. The prescription of medical cannabis is decided by 
the subject and his or her physician prior to enrolling the subject in the study. The principal investigator has 
no control over the prescribing/authorization or administration of the cannabis product.

4.2 
Study Medication: Cannabinoid Content Calculation 
On entering study medication information into REDCap Cloud, the preprogrammed algorithm will calculate 
the intake amount of mgs of THC and CBD for all formulations, and whether it was inhaled or ingested. 
Only limited data exist on the plasma concentration of circulating cannabinoids and their metabolites 
resulting from inhalation of cannabis products. It is known that factors influencing this include, but are not 
limited to, pattern of smoking or vaping (length of inhalation), as well as the flower combustion 
temperature. It is possible that these data may be calculated in retrospect (unlike other formulations that 
will allow for real time mg calculation), if more structured studies are conducted to evaluate the cannabinoid 
intake from smoked and/or vaped products, from different flower varieties. 
 
4.3 
Study Medication Safety Information 
Cannabis and cannabinoids are generally considered to be well-tolerated, although there is a large degree 
of individual difference in the side effects seen. A review of medical cannabis trials found that 96.6% of 
side effects were not serious, with the most common side effects of acute use being22: 
- 
Somnolence 
- 
Dizziness 
- 
Drowsiness 
- 
Fatigue 
- 
Tachycardia (increased resting heart rate) 
- 
Temporary impairment of sensation and body functions 
- 
Intoxication or feeling “high” 
- 
Nausea 
- 
Vomiting 
- 
Cough 
- 
Abdominal Pain 
 
Withdrawal symptoms from chronic use of cannabis can occur, usually within 1-2 days following 
discontinuation. The most common withdrawal symptoms include irritability, anxiety, sleep difficulties, 
craving, headache, restlessness, and anger or aggression, which usually resolve within 1-2 weeks.

4. Subject has a suspected or confirmed cardiovascular disease. 
5. Subject is a liver transplant recipient or with severely compromised liver function. 
 
6.3 
Subject Withdrawal from Study Participation 
Subjects are free to withdraw from the study at any time. Subjects who start taking medical cannabis from 
another licensed producer or withdraw consent for study participation will be contacted by the site physician 
or study site personal to complete an Exit assessment as soon as possible. 
Subjects that have received ST products and started using them for treatment of chronic pain, will be entered 
in the data analysis population, unless they have withdrawn consent together with withdrawing from the 
study. This is described in more detail, in the Statistical Analysis Plan. 
The site physician, by joining the study, confirms commitment to subject retention through coaching, 
counseling, and education. 
The site physician may withdraw a subject from the study in the following circumstances: 
• 
Subject experiences a serious adverse event (SAE) or other safety concerns. 
• 
Subject does not benefit from ST product treatment. 
• 
Subject meets any exclusion criteria. 
• 
Noncompliance with the study protocol. 
• 
Administrative reasons or study termination (e.g., Sponsor decision). 
• 
Other factors determined by the physician to affect the eligibility of subjects to continue.

OUTCOME ASSESSMENTS 
 
7.1 
Study Endpoints 
Primary endpoints 
•

changes over time in: 
(1) average daily dose of THC and CBD (in mg); 
(2) route of administration (inhaled or ingested). 
 
Secondary endpoints 
• 
Subject selection of ST treatment regimen and changes over time in: 
(1) average daily dose of THC and CBD (in mg); 
(2) route of administration (inhaled or ingested). 
• 
Change in BPI-SF responses from baseline. 
• 
Change in EQ5D-5L responses from baseline. 
• 
PGI-C for the target treatment goal. 
• 
CGI-I for the target treatment goal. 
• 
In subjects taking an opioid, changes in opioid use over time (calculated as milligram morphine 
equivalents [MME]/day). 
• 
Among subjects taking other medication, total daily dose change over time. 
 
Safety endpoint 
• Incidence of AEs stratified by product and formulation. 
7.2 
Study Assessments 
 
7.2.1 
EQ5D-5L- Euro QoL 
EQ5D-5L is a 5-category questionnaire (with a total of 6 questions) assessing mobility, self-care, usual 
activities, pain/discomfort, anxiety/depression, and overall health on a scale from 0-100 (where 100 denotes 
the best, and 0 the worst health)28. 
 
7.2.2 
BPI-SF 
The BPI-SF is a 9-item self-report questionnaire that is quickly and easily administered to subjects with 
chronic pain. The questionnaire includes 6 pain items that assess the spatial and temporal characteristics of 
pain (e.g., location, 24-hour worst pain, 24-hour average pain, pain right now); 2 items that ask about current 
treatments assumed for chronic pain and pain relief; and 1 pain interference item (with parts A–G) were 
respondents rate the level of interference of pain with general activity, mood, walking ability, normal work, 
social relations, sleep, and enjoyment of life over the past 24 hours24. 
 
7.2.3 
PGI-C 
The PGI-C is a simple 1-item self-report outcome measure that assesses a subject’s overall treatment 
satisfaction using a 7-point Likert-type scale. The PGI-C shows good performance and high responsiveness 
in subjects with chronic pain and is often more responsive than primary measures of pain intensity, possibly 
because the PGI-C captures additional elements of the analgesic response such as physical and 
psychological functioning25. 

Protocol #710-4502 
25 November 2020 
CONFIDENTIAL
Page 23 of 79 
 
 
7.2.4 
CGI-I 
The CGI-I is a simple 1-item clinician-reported outcome measure, similar to the PGI-C, that assesses a 
clinician’s overall impression of subject improvement in response to treatment using a 7-point Likert-type 
scale. Although frequently used in clinical trials focused on mental disorders, the CGI has also been 
evaluated in a context of chronic pain and correlates well with subject responses to the PGI-C26. 
 
7.2.5 
Determination of Opioid Consumption 
Physicians will confirm subjects who take an opioid at baseline or who start an opioid during the study, and 
will be asked to report the opioid type and MME, so that opioid consumption (and any opioid-sparing effect 
of the ST treatment regimen) can be examined over time. 
 
7.2.6 
Other Concomitant Medications 
Physicians will confirm subjects who take any non-opioid concomitant medication for pain at baseline, or 
who start it during the study, and will be asked to report the medication type. The following medication 
categories have been identified as common medication classes taken by chronic pain patients: Nonsteroidal 
Anti-inflammatory Drugs 
(NSAIDs) and 
Acetaminophen, 
Antidepressants, 
Anticonvulsants, 
Benzodiazepines and Muscle Relaxants. Physicians will be asked to report the medication type and total 
daily dose, and any changes throughout the study. 
 
7.2.7 
AEs/SAEs 
All enrolled subjects and site physicians will receive guidance on AE reporting during the investigator 
training. Spontaneous AE reporting will be entered in REDCap Cloud by the subject, during at-home 
follow-up (subject to verification by physician at physician-verified follow-up). Physicians will classify 
each AE by seriousness, severity and inferred relation to the study product in the Physician AE form as 
described below. The GPVD will also review all SAEs with respect to applicable regulatory requirements. 
 
7.2.7.1 
AE Definition 
An AE is any untoward medical occurrence in a subject administered a pharmaceutical product and which 
does not necessarily have a causal relation with treatment. An AE can therefore be any unfavorable and 
unintended sign, symptom, psychological effect, or disease associated with the use of a medicinal product, 
whether or not related to the medicinal product. 
 
7.2.7.2 
SAE Definition 
An AE will be considered serious if it results in 1 or more of the following outcomes: 
• 
Death 
• 
Life-threatening (i.e., at immediate risk of death) 
• 
Subject in-subject hospitalization or prolongation of existing hospitalization 
• 
Persistent or significant disability/incapacity 
• 
Congenital anomaly/birth defect 
• 
Any other AE that the Investigator or company judges to be serious or which is defined as serious by 
the local regulatory agency. 
 
Important AEs that may not result in death, be life threatening, or that do not require hospitalization may 
be considered serious when, based upon appropriate medical judgment, they may jeopardize the subject or 
may necessitate medical or surgical intervention to prevent one of the outcomes listed in the definition 
above. For this registry, the Important Medical Event (IME) list will be used as a reference for the 
assessment of medically significant adverse events30.

25 November 2020 
CONFIDENTIAL
Page 24 of 79 
 
 
7.2.7.3 
AE Severity 
The physician will assess the severity of all AEs reported in eCRFs as mild, moderate, or severe. For 
consistency, these intensity grades have been defined as follows: 
 
Mild: 
An event that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual activities 
of daily living. 
Moderate: 
An event that is alleviated with additional specific therapeutic intervention. The event 
interferes with usual activities of daily living and may cause discomfort but poses no 
significant or permanent risk of harm to the subject. 
Severe: 
An event that requires intensive therapeutic intervention. The event interrupts usual 
activities of daily living or significantly affects clinical status. 
 
7.2.7.4 
Relationship of AEs to Study Products 
The physician will assess the relation of each AE/SAE to the study product after careful consideration and 
in accordance with the following guidelines: 
Definitely related: The AE/SAE is clearly related to the study product (an alternative cause is unlikely). 
Probably related: The connection to the study product can be made with a high degree of certainty. This 
causal relation is assigned when the AE/SAE meets the following criteria: 
• 
Follows a reasonable temporal sequence from administration of the study product. 
• 
Cannot be reasonably explained by the known characteristics of the subject’s clinical state, 
environmental or toxic factors, or other modes of therapy administered to the subject. 
• 
Follows a known pattern of response to the study product. 
• 
Reappears upon subsequent challenge with the study product. 
Possibly related: The connection to the study product appears unlikely but cannot be ruled out with 
certainty. This causal relation is assigned when the AE/SAE meets the following criteria: 
• 
Follows a reasonable temporal sequence from administration of the study product. 
• 
May have been produced by the subject’s clinical state, environmental or toxic factors, or other modes 
of therapy administered to the subject. 
• 
Follows a pattern of response to the study product. 
Unlikely related: The AE/SAE is unlikely related to the study product when the AE or SAE meets the 
following criteria: 
• 
Does not follow a reasonable temporal sequence from administration of the study product. 
• 
May readily have been produced by the subject’s clinical state, environmental or toxic factors, or other 
modes of therapy administered to the subject. 
• 
Does not follow a known pattern of response to the study product. 
• 
Does not reappear or worsen when the study product is re-administered. 
Not related: The AE/SAE is judged to be clearly and incontrovertibly due only to a cause other than the 
study product (e.g., disease, environment, etc.) and does not meet the criteria for a relation with the study 
product.

DATA HANDLING AND RECORD KEEPING 
 
8.1 
Data Collection 
Data collection will be achieved through a combination of subject and physician reporting with the aid of 
automated reminders and MSL contact. All data and study-specific forms (including eICF and eCRF forms), 
will be centralized electronically via REDCap (Research Electronic Data Capture Software) Cloud. A pdf 
copy of the ICF will be emailed to subjects for their own records. Access to REDCap Cloud will be 
password-protected and all subjects and physicians will be required to register with a unique username and 
password. 
Physicians will be trained on use of REDCap Cloud during Investigator training and ensure that subjects 
understand and are able to use REDCap Cloud software. REDCap Cloud is accessible by computer, tablet, 
or smartphone. Subjects who elect to complete at-home follow-up assessments online will receive an 
automated email 1 week prior and the day of at-home follow-up with a reminder to complete the 
questionnaire. 
 
8.2 
Data Management 
The REDCap Cloud system uses a variety of mechanisms for checking data at the time of entry including 
skip logic, range checks, and data type checks. Upon receipt of new data, the personnel at the Methods 
Center will query all missing, implausible, or inconsistent data. Study site personnel will be able to conduct 
a review of open queries in the system and will be trained/required to respond promptly. 
 
8.3 
Data Monitoring 
Data will be monitored by the Sponsor consistent with International Council for Harmonization (ICH) Good 
Clinical Practice (GCP) guidelines. Source data verification will be performed remotely on 10% of study 
sites. Continuous, real-time monitoring of data quality and completeness will be performed remotely by the 
Sponsor. The registry project management team will periodically review site compliance (completion of 
scheduled visits and questionnaires), send reminders for missed at-home subject follow-up questionnaires, 
and guarantee that all efforts are made to contact subjects who discontinue the study or ST treatment prior 
to 1-year follow-up. Issues with data quality or completeness will be addressed on a case-by-case basis and, 
if necessary, brought to the attention of the Sponsor when requiring remedial action (e.g., retraining of a 
site). 
 
8.4 
Record Retention 
Research data in electronic form will be stored and managed in a secure manner in accordance with 
applicable federal regulations and guidelines and according to institutional policies and practices. Further, 
any hard copy documents containing subject data will be stored in secure document containers (file cabinets, 
lockers, drawers, etc.) in accordance with standard document management practices. At all times, only listed 
key personnel specifically designated and authorized by the Sponsor shall have access to any research 
related documents, including electronic data. All such personnel will be properly trained and supervised 
regarding the management and handling of confidential materials. The Sponsor assumes full responsibility 
for such training. Site physicians will only have authorization to access data from their respective sites. 
 
8.5 
Database Access 
The database resulting from this registry is the sole property of Canopy Growth and will only be used for 
research purposes. During the study, the REDCap Cloud database will be accessible to the Sponsor by 
username and password for the sole purpose of generating summary reports. All forms of data

dissemination will require prior approval from the Sponsor as specified in the Scientific Committee 
agreement. Site physicians will only have access to their subject’s data during the study, but are not 
permitted to analyze their data or disseminate the results publicly. Site physicians will not have access to 
the full database; however, a formal request for specific analyses of the entire database can be submitted to 
the Scientific Committee. Not all requests will be approved.

Statistical overview 
The Sponsor will perform statistical analyses. The Sponsor or designee will extract and analyze descriptive 
data every 6 months. This will be done to keep sites apprised of study progress. A de-identified summary 
report will be generated and delivered to all registered site physicians. 
The report will indicate: 
• 
The number of physician-collaborators stratified by country. 
• 
The number of subjects enrolled stratified by country. 
• 
Subject demographics, chronic pain classification, and treatment goal. 
• 
Subject concomitant medication use. 
• 
Subject ST treatment regimens. 
• 
Incidence of AEs per individual ST product. 
Upon database lock a series of analysis will be conducted to address study objectives. For each analysis, 
the normality of the data distributions will be ascertained using the Shapiro-Wilk test of normality and 
Levene’s test of equality of error variance. Descriptive statistics (frequencies, means, and standard 
deviations for normally distributed parametric data; medians and interquartile ranges for nonparametric 
data) will be used to characterize the sample. Outcome analyses will include a change in ST regimen; a 
change in reported opioid consumption in MME/day; change in daily dose of other medications, including 
analgesics, sedatives, and benzodiazepines; change in responses to BPI-SF items and EQ-5DL items; initial 
PGI-C and changes over time; and initial CGI-I and changes over time. For the safety endpoint, AEs will 
be tabulated descriptively. Detailed analyses are outlined in the Statistical Analysis Plan. 
 
9.2 
Sample Size 
This study will include as many eligible subjects as are willing to participate; however, site criteria must be 
met. 
Given a continuous enrollment design, the study will include two enrollment milestones over the 2-year 
study period. Milestone 1, at the end of year 1 will be to recruit 750 subjects. Milestone 2, at the end of year 
2, will be recruit 750 subjects. Together, recruitment milestones result in enrolling a total of up to 1500 
subjects. 
The number of subjects may vary based on the real-life use of ST products. Sites will be recruited from 
countries where ST products are available: Canada, United Kingdom, Germany, and Australia. Sites from 
additional countries may be included as ST products become available in those countries. 
The present study has an observational design that poses low-burden for subjects, as the number and 
frequency of in-clinic (telemedicine) visits represent those necessary for adequate monitoring of treatment 
for chronic pain and at-home follow-ups will be completed using a simple online app and take no longer 
than 15 minutes to complete. On this premise, we did not restrict the sample size based on an estimated 
minimum required sample. Furthermore, the observational nature of the primary endpoint (daily average 
dose [in mg] of THC and CBD and mode of administration [inhaled or ingested]), did not permit a statistical 
calculation of a sample size. A sample size of up to 1500 subjects is consistent with similar previous 
observational registry studies.

9.3 
Handling of Dropouts, Missing Data 
For descriptive summaries of data, there will be no imputation for missing data, unless otherwise stated. 
All data collected prior to a subject withdrawing will be listed and included in data summaries. 
For analyses involving linear mixed effects modeling, data points that are missing due to participant dropout 
will be handled assuming that data are missing at random (MAR) conditional on observed information, 
which is less restrictive than missing completely at random assumed in fixed effects analyses such as 
ANCOVA. In this procedure, all available cases, including those with missing information, will be included 
in the analyses using full information maximum likelihood estimation. This procedure increases power and 
reduces bias in parameter estimation. 
 
9.4 
Statistical Software 
Data manipulation, tabulation of descriptive statistics, calculation of inferential statistics, and graphical 
representations will be performed using R (version 4.0 or higher)31 or the SuperMix statistical software. 
Mixed effects models of continuous outcomes will be conducted using the nlme32 and/or lme433 packages, 
mixed effects models of ordinal outcomes with the mixor34 or ordinal35 package, mixed effects models of 
binomial outcomes using the lme4 package33, and mixed effects hurdle regression models with the 
GLMMadaptive package36. 
If the use of other software is warranted, the final clinical study report will detail what software was used 
and for what purposes.

10. ETHICS 
 
10.1 Ethical Conduct of the Study 
The study will be conducted consistent with consensus ethics principles derived from international ethics 
guidelines including the ICH GCP, the Declaration of Helsinki, and applicable local regulatory 
requirements and laws. The registry will only launch after receiving ethical approval from the Canadian 
SHIELD ethics review board and approval will be renewed on a yearly basis. 
Any site that joins the registry will provide additional ethics approval as required by their local regulatory 
bodies as part of the feasibility evaluation. Canopy Growth will review all outside ethics approvals and only 
sites with ethical approval will receive a contract and invitation to the investigator training. 
 
10.2 Subject Information and Consent 
Informed consent will be obtained prior to the subject participation in any study activities. Prior to obtaining 
consent, the site physician will ensure that: 
• 
The potential subject has had a discussion with an individual knowledgeable about the research, 
including the nature and objectives of the study and possible risks associated with participation. 
• 
The potential subject is given a copy of written material (e.g., consent documents, Spectrum 
Therapeutics leaflet) that has received prior approval by the appropriate ethics committee(s) and 
meets local regulatory and legal requirements. 
• 
The potential subject has ample opportunity to ask questions about the study. 
• 
An assessment of capacity has taken place. For consent to be ethical and lawfully valid, subjects in 
this study must be capable of providing informed consent for their participation. A capable person 
will: 
▪ 
Understand the purpose and nature of the research. 
▪ 
Understand what the research involves, its benefits (or lack of benefits), risks, and 
burdens. 
▪ 
Understand how their interests and privacy are protected. 
▪ 
Understand the alternatives to participation. 
▪ 
Be able to retain the information long enough to make an effective decision. 
▪ 
Be able to make a free choice. 
▪ 
Be capable of making this particular decision at the time it needs to be made.

11. STUDY TERMINATION 
The Sponsor reserves the right to terminate the participation of either an individual site or the study at any 
time, for any reason, including, but not limited to, the following: 
• 
The information on the product leads to doubt as to the benefit/risk ratio. 
• 
Recommendation of the Scientific Committee. 
• 
Subject enrollment is unsatisfactory. 
• 
Noncompliance of the site physician, delegated staff with any provision of the study protocol, and 
breach of the applicable laws and regulations. 
As directed by the Sponsor, site physicians will be notified and required to inform local ethics committees 
and all study subjects of study termination. 
Local ethics committees or regulatory authorities may also decide to stop the study, part of the study, or a 
study site at any time.

12. PUBLICATION POLICY 
The information obtained during the conduct of this study is considered confidential. It may be used by, or 
on behalf of the Sponsor for regulatory purposes as well as for the general development of ST medical 
cannabis products. All information supplied by the Sponsor in connection with this study shall remain the 
sole property of the Sponsor and is to be considered confidential information. 
The site physicians will not disseminate any publication or release pertaining to the study and/or results of 
the study without the Sponsor’s express written consent; the Sponsor will not unreasonably withhold its 
approval. For example, withholding approval for publication will be deemed unreasonable if such a decision 
is based exclusively on the fact that the results of the study are negative or equivocal. In contrast, 
withholding approval will be deemed reasonable if the validity of the study methodology or results are in 
question. Different parts of the study may be published separately.
