A randomized, double blind, study of dronabinol as a palliative agent in the treatment of pain, inflammation, and other complications of sickle cell disease (SCD).
A randomized, double blind, study of dronabinol as a palliative agent in the treatment of pain, inflammation, and other complications of sickle cell disease (SCD).
Primary Objective: To determine whether dronabinol will improve pain and QOL in adults with SCD and chronic pain.
Secondary Objectives: To assess dronabinol's effect on markers of inflammation in patients with SCD compared to placebo.
To determine the safety and tolerability of dronabinol use in adults with SCD compared to placebo.

| WBC with differential | a marker of Inflammation. The blood differential test measures the percentage of each type of white blood cell (WBC) in the blood. It also reveals if there are any abnormal or immature cells. | end of study at 8 weeks |
| C-reactive protein (CRP) | marker of Inflammation. C-reactive protein (CRP) is produced by the liver. The level of CRP rises when there is inflammation throughout the body. It is one of a group of proteins, called acute phase reactants, that go up in response to inflammation. The levels of acute phase reactants increase in response to certain inflammatory proteins called cytokines. These proteins are produced by white blood cells during inflammation. | end of study at 8 weeks |
| tryptase | marker of Inflammation. tryptase is an enzyme found in mast cells | end of study at 8 weeks |
| substance P | marker of Inflammation. Substance P ("P" standing for "Preparation" or "Powder") is a neuropeptide - but only nominally so, as it is ubiquitous. Its receptor - the neurokinin type 1 - is distributed over cytoplasmic membranes of many cell types (neurons, glia, endothelia of capillaries and lymphatics, fibroblasts, stem cells, white blood cells) in many tissues and organs. SP amplifies or excites most cellular processes. | end of study at 8 weeks |
| Vascular cell adhesion protein 1 (VCAM-1) | marker of Inflammation. plasma levels of oxidative stress and adhesion molecules | end of study at 8 weeks |
| cytokine IL1a | marker of Inflammation. Interleukin 1 alpha (IL-1α) also known as hematopoietin 1 is a cytokine of the interleukin 1 family that in humans is encoded by the IL1A gene. | end of study at 8 weeks |
| cytokine IL1b | marker of Inflammation. Interleukin 1 beta (IL-1β) also known as leukocytic pyrogen, leukocytic endogenous mediator, mononuclear cell factor, lymphocyte activating factor and other names, is a cytokine protein that in humans is encoded by the IL1B gene. | end of study at 8 weeks |
| cytokine IL6 | marker of Inflammation. Interleukin-6 (IL-6) is a pleiotropic cytokine with central roles in immune regulation, inflammation, hematopoiesis, and oncogenesis. | end of study at 8 weeks |
| cytokine IL4 | marker of Inflammation. The interleukin 4 (IL4, IL-4) is a cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. | end of study at 8 weeks |
| cytokine IL10 | marker of Inflammation. Interleukin 10 (IL-10), also known as human cytokine synthesis inhibitory factor (CSIF), is an anti-inflammatory cytokine. | end of study at 8 weeks |
| tumor necrosis factor alpha (TNFα). | marker of Inflammation. Tumor necrosis factor (TNF), a 17 kDa protein consisting of 157 amino acids, is a homotrimer in solution that is mainly produced by activated macrophages, T lymphocytes, and natural killer (NK) cells. | end of study at 8 weeks |
| PROMIS domains | PROMIS domains for anxiety, appetite, nausea, and cognitive function, opioid use in oral morphine equivalents (OME), episodes of emergency room, hospital, or psychiatric facility utilization. Each domain scale from 20 to 80, median of 50 and SD of 10. Higher scores represent better health outcomes. Total scale from 20 to 80, median of 50 and SD of 10. Higher scores represent better health outcomes. | end of study at 8 weeks |
| Columbia suicide severity rating scale | Columbia suicide severity rating scale. Full range from 0 to 9. Higher score represents higher intensity suicidal ideation. | end of study at 8 weeks |
| Prodromal questionnaire brief version (PQ-B) | Prodromal questionnaire brief version: 21-item self-report instrument. Full scale range from 0 to 21, higher score represents poorer health outcomes | end of study at 8 weeks |
| PROMIS domain for neuropathic pain quality | Total scale from 20-80, median of 50 and SD of 10. Higher scores represent worse outcomes. | end of study at 8 weeks |
| PROMIS domain for nociceptive pain quality | Total scale from 20-80, median of 50 and SD of 10. Higher scores represent worse outcomes. | end of study at 8 weeks |
| The Leeds assessment of neuropathic symptoms and signs (LANSS) Pain Scale | The Leeds assessment of neuropathic symptoms and signs (LANSS) Pain Scale comprises of a 7-item pain scale, including the sensory descriptors and items for sensory examination. Out of the seven items in the Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale (LANSS), five are symptom related and two are examination items. Full scale from scores between 0 and 24, higher score represents poorer health outcomes. | end of study at 8 weeks |
