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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Participants Caregivers Investigators Outcome Assessors
Dronabinol and placebo will be over-encapsulated so that neither participants nor investigators are aware of the subjects assignment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dronabinol

BID 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.
