Brief summary

Study Objectives: Primary reduction of pain and reduction in overall opioid utilization. Secondary improvement in overall patient well being, weight stabilization with increased appetite, improved oxygen saturation, improvement or prevention of nausea and vomiting. Study Rationale: To determine optimum use and dosing of medical marijuana (CBD:THC) for pain and symptom management. Study Population: This study specifically will enroll cancer and non-cancer patients as a primary diagnosis suffering from pain and having a terminal illness (defined as having less than 6 months to live) requiring end of life care.

Detailed description

Primary Endpoint: Primary reduction of pain and reduction in overall opioid utilization as evidenced by overall reduction in numeric pain scores and MME (Morphine Milliequivalents) Secondary and Exploratory endpoints:Secondary improvement in overall patient well being, weight stabilization with increased appetite, improved oxygen saturation, improvement or prevention of nausea and vomiting. Endpoints evaluation will be based on change from Baseline using the Modified Edmonton Assessment Scale. Study design: This will be an open-label study. Patients will choose to participate in a Marijuana adjuvant treatment group, receiving marijuana in combination with standard opioid therapy. Subject number: Minimum 66 patients Treatment Duration: Minimum 5 days Duration of follow up: Patients' initial opioid dose, dosing schedule and numeric pain score will be recorded. For the duration of the study (at least five days) changes in opioid doses and numeric pain scores will be tracked daily. Marijuana will be administered to the patient via oral route three times daily for at least five days. Patients will receive standardized CBD:THC product provided by NIDA. On admission to the study, a modified Edmonton Symptom assessment scale to quantify baseline appetite, depression, nausea, vomiting, overall well-being, and anxiety. Data Tracking: Primary objective tracking will include average numeric pain scores and number of opioid dosage increases and average daily opioid amount (mg equivalents of morphine). Secondary objectives include Weight, Appetite, N/V, O2 Saturation, Self-reported data points from the modified Edmonton Assessment Scale.

Design outcomes

Primary

MeasureTime frameDescription
Primary Reduction of Painminumum 3 daysA numeric pain scale (Units on a scale with the higher number indicating worse pain) was used to assess pain from a range of 0 to 10.
Reduction in Overall Opioid Utilizationminimum of 3 daysReduction in overall opioid utilization was measured in units of mg after converting every patient's opioids into equivalent doses (e.g. 2mg of oral dilaudid = 1/4 oral morphine), with a stabilization or reduction in Morphine Mg Equivalents indicating a positive result.

Secondary

MeasureTime frameDescription
Improvement in Overall Patient Well Beingminimum 3 daysA modified Edmonton Assessment Scale was used. The Edmonton Symptom Assessment System (ESAS) is a questionnaire used to rate the intensity of common symptoms experienced by cancer patients, including pain, tiredness, nausea, depression, anxiety, drowsiness, appetite, well-being, and shortness of breath. A scale of 1 to 10 was used, where, 1 corresponds to the best well-being and 10 corresponds to the worst well-being.
Weight Stabilization With Increased Appetiteminimum 3 daysA modified Edmonton Assessment Scale was used. The Edmonton Symptom Assessment System (ESAS) is a questionnaire used to rate the intensity of common symptoms experienced by cancer patients, including pain, tiredness, nausea, depression, anxiety, drowsiness, appetite, well-being, and shortness of breath. Appetite was analyzed as an ordinal variable where 1 = finished 0\ 25% of meal, 2 = 25\ 50% of meal, 3 = 50\ 75% of meal, 4 = 75\ 100% of meal.
Improved Oxygen Saturationminimum 3 daysOxygen saturation was reported as a percentage, the greater the % O2 saturation the more positive the outcome.
Reduction or Prevention of Nausea and Vomitingminimum 3 daysA modified Edmonton Assessment Scale was used; the scale is a numeric 0-10 scale (Units on a scale where the higher the number the more nausea and vomiting the patient experienced).
