Drug: Placebo
Registration Number
NCT05519111
Lead Sponsor
Icahn School of Medicine at Mount Sinai
Brief Summary

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).

Detailed Description

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.

DronabinolDronabinolBID for 8 weeks. Dosage will be individualized per patient. In days 1-4 of the study each patient will be titrated from 5mg bid to a minimum dose of 2.5 mg bid to a maximum dose of 10 mg bid depending on patient preference.
Primary Outcome Measures
NameTimeMethod
Patient Reported Measurement Outcome Information System (PROMIS) pain impact scoreend of study at 8 weeks

Change in Patient Reported Measurement Outcome Information System (PROMIS) pain impact score. Total scale from 20-80, median of 50 and SD of 10. Higher score represent poorer health outcomes.

Secondary Outcome Measures
NameTimeMethod
tumor necrosis factor alpha (TNFα).end of study at 8 weeks

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.

The Leeds assessment of neuropathic symptoms and signs (LANSS) Pain Scaleend of study at 8 weeks

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.

Adult Sickle Cell Quality of Life Information System (ASCQ-Me) Pain impactend of study at 8 weeks

Total scale from 20 to 80, median of 50 and SD of 10. Higher scores represent better health outcomes.

Quality of Life Outcomesend of study at 8 weeks

ASCQ-Me survey domains for emotional impact, social impact, stiffness, and sleep.

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.

WBC with differentialend of study at 8 weeks

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.

C-reactive protein (CRP)end of study at 8 weeks

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.

tryptaseend of study at 8 weeks

marker of Inflammation. tryptase is an enzyme found in mast cells

cytokine IL10end of study at 8 weeks

marker of Inflammation. Interleukin 10 (IL-10), also known as human cytokine synthesis inhibitory factor (CSIF), is an anti-inflammatory cytokine.

Vascular cell adhesion protein 1 (VCAM-1)end of study at 8 weeks

marker of Inflammation. plasma levels of oxidative stress and adhesion molecules

cytokine IL1aend of study at 8 weeks

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.

substance Pend of study at 8 weeks

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.

cytokine IL1bend of study at 8 weeks

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.

cytokine IL6end of study at 8 weeks

marker of Inflammation. Interleukin-6 (IL-6) is a pleiotropic cytokine with central roles in immune regulation, inflammation, hematopoiesis, and oncogenesis.

cytokine IL4end of study at 8 weeks

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.

PROMIS domain for nociceptive pain qualityend of study at 8 weeks

Total scale from 20-80, median of 50 and SD of 10. Higher scores represent worse outcomes.

PROMIS domainsend of study at 8 weeks

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.

Columbia suicide severity rating scaleend of study at 8 weeks

Columbia suicide severity rating scale. Full range from 0 to 9. Higher score represents higher intensity suicidal ideation.

PROMIS domain for neuropathic pain qualityend of study at 8 weeks

Total scale from 20-80, median of 50 and SD of 10. Higher scores represent worse outcomes.

Prodromal questionnaire brief version (PQ-B)end of study at 8 weeks

Prodromal questionnaire brief version: 21-item self-report instrument. Full scale range from 0 to 21, higher score represents poorer health outcomes
