Chronic Pain Clinical Trial
Official title:
Dose-Titration Study to Evaluate the Opioid-Sparing Effect of Dronabinol When Coadministered With Opioid Analgesics to Chronic Pain Patients
This study will be a 12-week, open-label trial that is designed to evaluate the Opioid-Sparing effect of Dronabinol at ranging doses when coadministered with the opioid analgesics that are currently being prescribed to patients for their chronic pain condition. The purpose of this trial will be to assess the effectiveness of Dronabinol when combined with opioid analgesics to relieve pain at lower opioid doses and to evaluate any reduction of opioid-related side effects. Participants will take the study-drug, Dronabinol, along with their regular prescribed opioids and the results will be evaluated and analyzed according to defined endpoints.

---|---|---|---|---|
Primary | Pain Intensity Scale (0-10) | To measure the change in pain intensity from baseline using the Opioid Sparing Diary Toolkit. The measurement of the pain intensity will be derived from the Brief Pain Inventory (Short-Form) item #3. "Please rate your pain by marking the box beside the number that best describes your pain at its worst in the last 24 hours." The score is reported as a value between 0 and 10, with 0 indicative of no pain, and 10 indicative of "pain as bad as you can imagine". The score will be considered a continuous level of measurement. | Daily (Days 1-82) | |
Primary | Self-Reported Opioid Use (Opioid Dose) | To measure the change in opioid dose from baseline using the Opioid Sparing Diary Toolkit | Daily (Days 1-82) | |
Primary | Self-Reported Opioid Use Frequency (Opioid Dose Frequency) | To measure the change in opioid use frequency from baseline using the Opioid Sparing Diary Toolkit | Daily (Days 1-82) | |
Secondary | Brief Pain Inventory (BPI) | To evaluate and measure any changes in pain history, intensity, location, relief, and life interference indicators from baseline | Study Visits 1-5 (Days 1, 14, 28, 56, 82) | |
Secondary | Hospital and Anxiety Depression Scale (HADS) | To measure the change in depression and generalized anxiety from baseline. The HADS measures levels of anxiety and depression that a patient is experiencing. The HADS is a fourteen item scale. Seven of the items relate to a factor that measures anxiety and seven relate to a factor that measures depression. The seven items for each factor are summed into a total score and range from 0 to 21, with higher scores indicative of greater anxiety/depression. The scores will be analyzed as continuous level variables and one-sided paired-samples t-tests will be used to compare mean scores for anxiety and depression for all subjects between Week 1 (baseline) and Week 12 (EOS). | Study Visits 1-5 (Days 1, 14, 28, 56, 82) | |
Secondary | Side Effect Checklist 29-item | To evaluate the presence or absence of side effects associated with the intervention | Study Visits 1-5 (Days 1, 14, 28, 56, 82) | |
Secondary | RAND Health Survey 36-item | To measure the change in overall quality of life from baseline | Study Visits 1-5 (Days 1, 14, 28, 56, 82) | |
Secondary | MOS Sleep Scale | To measure the change in quality of sleep from baseline. The MOS Sleep Scale Self Report includes 12 items which measure 7 individual continuous-level factors relating to sleep quality: (a) sleep disturbances, (b) snoring, (c) sleep short of breath or headache, (d) sleep adequacy, (e) sleep somnolence, (f) sleep problems index I, and (g) sleep problems index II. Each of the seven factors is scored via a two-step process such that higher resulting scores are indicative of greater sleep problems. All 7 scores are measured at the continuous level. | Study Visits 1-5 (Days 1, 14, 28, 56, 82) | |
Secondary | Treatment Satisfaction Questionnaire for Medication (TSQM) | To measure the change in satisfaction with medication from baseline | Study Visits 1-5 (Days 1, 14, 28, 56, 82) | |

Secondary | OSD: Mood Scale Self Report (0-10) | To measure the change in Mood from baseline. The Mood Scale is a 10 item Likert-scaled instrument with each of the 10 items scored from 1 = absolutely miserable to 10 = absolutely happy. The scores for each of the 10 items will be summed into a mood total score. The mood total score can range from 10 to 100, with higher scores indicative of happier states. The mood total score is a continuous level of measurement. | Daily (Days 1-82) | |
Secondary | OSD: Sleep Scale Self Report (0-10) | To measure the change in Quality of Sleep from baseline. The Sleep Scale is a 10 item Likert-scaled instrument with each of the 10 items scored from 1 = worst imaginable to 10 = best . The scores for each of the 10 items will be summed into a sleep total score. The sleep total score can range from 10 to 100, with higher scores indicative of better quality sleep. The sleep total score is a continuous level of measurement. | Daily (Days 1-82) | |

Secondary | FITBIT: Sleep Tracker | To measure the change in quantity and quality of sleep from baseline | Daily (Days 1-82) | |
