Criteria

Inclusion Criteria:

  • The patient has advanced cancer for which there is no known curative therapy
  • The patient has a clinical diagnosis of cancer related pain, which is not alleviated with their current optimized opioid treatment
  • The patient is receiving an optimized maintenance dose of Step III opioid therapy, preferably with a sustained release preparation, but also allowing a regular maintenance dose of around the clock use of immediate release preparations
  • The patient is receiving a daily maintenance dose Step III opioid therapy of less than or equal to a total daily opioid dose of 500 mg/day of morphine equivalence (including maintenance and break-through opioids)
  • The patient is using no more than one type of break-through opioid analgesia

Exclusion Criteria (abbreviated):

  • Have any planned clinical interventions that would affect their pain (e.g., chemotherapy or radiation therapy where, in the clinical judgment of the investigator, these would be expected to affect pain)
  • The patient is currently using or has used cannabis or cannabinoid based medications within 30 days of study entry and is unwilling to abstain for the duration of the study
  • Has experienced myocardial infarction or clinically significant cardiac dysfunction within the last 12 months or has a cardiac disorder that, in the opinion of the investigator would put the patient at risk of a clinically significant arrhythmia or myocardial infarction
  • Has significantly impaired renal function
  • Has significantly impaired hepatic function
  • Female patients of child-bearing potential and male patients whose partner is of child-bearing potential, unless willing to ensure that they or their partner use effective contraception, for example, oral contraception, double barrier, intra-uterine device, during the study and for three months thereafter (however, a male condom should not be used in conjunction with a female condom as this may not prove effective)
