About
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.

- 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;

Exclusion criteria
-
Severe or unstable Systemic lupus erythematosus (SLE), such as any one of the following:
- A British Isles Lupus Activity Group (BILAG) A score in one or more BILAG domains at Screening;
- Treatment with any intraarticular, intravenous, or intramuscular systemic corticosteroids within 14 days of Screening;
- Treatment with oral prednisone > 10 mg per day or > 20 mg every other day (or equivalent dose of another corticosteroid) within 14 days of Screening;

- Actively listed on an organ transplantation list or have received an organ transplant other than a corneal transplant.
-
Significant diseases or conditions other than SLE that may influence response to the study product or safety, such as:
-
Active bacterial or viral infection requiring systemic antibiotic or anti-viral treatment within 14 days before Visit 1 (Day 1);
-
Acute or chronic hepatitis B or C infection;
-
Human immunodeficiency infection (HIV);
-
History of active tuberculosis or positive tuberculosis skin or blood test without: 1) completing a course of appropriate treatment; or ) having received at least one month of appropriate treatment prior to Visit 1 (Day 1) and continuing to receive appropriate treatment during the study;
-
No elective surgery should be planned from Visit 1 (Day 1) through Visit 6 (Day 112); or
-
A history of cancer except basal cell carcinoma or in situ carcinoma of the cervix treated with apparent success with curative therapy greater than one year before Visit 1 (Day 1).
-
Significant heart disease as defined by:
- Uncontrollable congestive heart failure, unstable angina, unstable atherosclerotic cardiovascular disease, significant arrhythmia requiring chronic therapy, pulmonary arterial hypertension with dyspnea, disability rated as New York heart Association Grade III or higher, severe systemic hypertension or severe peripheral vascular disease;
- Marked baseline prolongation of QT/QTc interval (i.e. repeated demonstration of a QTc interval ≥ 450 msec for males and ≥470 msec for females);
- History of risk factors for torsade de pointes (e.g., heart failure, hypokalemia, family history of long QT/QTc syndrome); or
- Clinically significant confirmed abnormality, as determined by the site investigator or qualified designee, on 12-lead Electrocardiogram (ECG) at Screening or Visit 1 (Day 1) before dosing.
-
-
History of chronic pain requiring treatment with narcotic analgesia for more than 14 days total within 6 months of baseline. This does not include self-limited pain associated with identifiable events such as surgery;
-
Current evidence of alcohol abuse (defined as 4 or more drinks per day on at least 4 days of the week) or history of abuse of illegal and/or legally prescribed drugs such as barbiturates, benzodiazepines, amphetamines, cocaine, or opioids during the 1 year prior to Screening;

- A newly positive QuantiFERON(R) blood test for tuberculosis, without: 1) completing a course of appropriate treatment; or ) having received at least one month of appropriate treatment prior to Visit 1 and continuing to receive appropriate treatment during the study. If the subject has a previous documented positive tuberculosis skin, then this testing does not need to be repeated. If the subject has a documented negative test result within the last year, testing does not need to be repeated, at the discretion of the site investigator.
- Hemoglobin < 8 g/dL;
- Neutrophils < 1.0 x 10^9/L;

When in doubt, the site investigator or qualified designee should discuss the situation with the Protocol Chairs.
