JBT-101 in Systemic Lupus Erythematosus (SLE)

The objective of this study is to evaluate the efficacy, safety, and tolerability of JBT-101 (also known as lenabasum) in systemic lupus erythematosus (SLE). * One hundred adults with active joint disease and at least moderate pain will be enrolled in this study to evaluate treatment of their systemic lupus erythematosus (SLE) with JBT-101. JBT-101 is a synthetic endocannabinoid receptor type 2 (CB2) agonist and an activator of the body's normal processes, to resolve innate immune responses without immunosuppression. * Participants will receive 2 doses of JBT-101 by mouth (three groups of varying doses) or, placebo, for 84 days and will continue to be followed for an additional 28 days. Participant visits to assess endpoints occur on Day 1, then every 2 weeks twice, then every 4 weeks three times, for a total of six visits. * The change in maximum daily pain Numerical Rating Scale (NRS) score from Baseline (Visit 1) will be assessed at every visit.
