1.Primary Outcome
Title Number of Patients With at Least 30% Improvement in Numerical Rating Scale (NRS) Average Pain Score From Baseline
Hide Description A positive 30% pain response is defined as a reduction of at least 30% in the mean NRS average pain score from baseline to week 5 (last 3 days). The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain or average pain in the last 24 hours" where 0 = no pain and 10 = pain as bad as you can imagine. No pain relates to the time prior to the onset of pain due to cancer. The average pain NRS was completed at the same time each day, i.e. bedtime in the evening.

2.Secondary Outcome
Title Change in Cumulative Average Pain Response Curves
Hide Description

The cumulative response to treatment is the percentage changes from baseline in the mean NRS pain score as defined as the 30% response.

The pain NRS was completed at the same time each day, i.e. bedtime in the evening. The patient was asked "on a scale of '0 to 10', please indicate the number that best describes your pain or average pain in the last 24 hours" where 0 = no pain and 10 = pain as bad as you can imagine. No pain relates to the time prior to the onset of pain due to cancer.

Title Change in Brief Pain Inventory – Short Form (BPI-SF)
Hide Description The BPI-SF is a 14-item questionnaire that asks patients to rate pain over the prior week and the degree to which it interferes with activities on a 0 to 10 scale, where 0=no pain and 10=pain as bad as you can imagine. Severity is measured as worst pain, least pain, average pain, and pain right now. The severity composite score was calculated as the arithmetic mean of the four severity items(range 0-10). the minimum value is zero and maximum is 10. A higher score represents a poor outcome.

The PAC-QoL was completed at baseline and then at the end of treatment. An overall score (range 0-4) was calculated at each visit and the difference determined. A positive difference in score represents an improvement.

Hide Description The MADRS comprises of 10 questions that are completed by the patient to determine their depression level. The MADRS was completed at Visit 2 (Baseline) prior to receiving the study drug and at Visit 4 (Week 5 or premature termination). Each item is scored on a 0-6 scale , where 0=no sadness to 6=extreme and continuous gloom and despondency, and the MADRS score is the sum of the 10 item scores (range 0-60). The higher the score the more severe the depression.

Hide Arm/Group Description Range of 11 to 16 sprays per day. Each actuation of oromucosal spray delivers 2.7mg delta-9-tetrahydrocannabinol (THC) and 2.5mg cannabidiol (CBD). Thus maximum daily dose is 43.2mg THC and 40mg CBD. Range of 6 to 10 sprays per day. Each actuation of oromucosal spray delivers 2.7mg delta-9-tetrahydrocannabinol (THC) and 2.5mg cannabidiol (CBD). Thus maximum daily dose is 27mg THC and 25mg CBD. Range of 1 to 4 sprays per day. Each actuation of oromucosal spray delivers 2.7mg delta-9-tetrahydrocannabinol (THC) and 2.5mg cannabidiol (CBD). Thus maximum daily dose is 10.8mg THC and 10mg CBD. Range of 1-16 sprays per day of placebo spray
