Brief summary: 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.


Eligibility criteria: Inclusion Criteria:

* Fulfills the updated American College of Rheumatology (ACR) 1982 Revised Criteria for the Classification of Systemic Lupus Erythematosus;
* At least 3 months of treatment with an anti-malarial drug such as hydroxychloroquine or a history of intolerance, contraindication, or unwillingness to take an anti-malarial drug;
* Meets the Safety of Estrogen in Lupus: National Assessment (SELENA) Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) definition of arthritis (Petri et al., 1999) or mild/moderate arthritis or tendonitis scored as a BILAG B on the updated BILAG 2004;
* Seven-day average of maximum of daily pain Numerical Rating Scale (NRS) scores ≥ 4 out of 10;
* Overlap with polymyositis, systemic sclerosis, Sjögren's syndrome, or rheumatoid arthritis is allowed, if, in the site investigator's judgment, the predominant clinical features are those of Systemic Lupus Erythematosus (SLE);
* Not expected by the site investigator to require a change in potential disease- modifying treatments for SLE from Screening through Visit 6 (Day 112);
* Willing to not start nor stop any Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) or potential disease-modifying medications or supplements for SLE from Screening through Visit 6 (Day 112), unless a change is recommended by the site investigator or other treating physicians;
