Brief Summary
This project is a multicenter, randomized, placebo-controlled, double-blind clinical trial that is designed to test whether treating patients who are at risk for development of lupus with hydroxychloroquine can slow accumulation of disease features. Effects on clinical progression of symptoms, patient-reported outcomes and changes in the immune markers of response will be measured and toxicity of the treatment will be assessed. This trial is a first step in testing a prevention strategy for lupus.

Patient Reported Outcome Physical Function
Measured every 12 weeks for 96 weeks
Patient Reported Outcomes Fatigue
Measured every 12 weeks for up to 96 weeks
- +5 more secondary outcomes
Study Arms (2)
Hydroxychloroquine
ACTIVE COMPARATORHydroxychloroquine will be administered as a once daily dose of 200 or 400 mg, based on the patient's weight. Treatment will be for 96 weeks.
Placebo oral capsule
PLACEBO COMPARATORPlacebo will be administered as one or two capsules as a single daily dose, based on the patient's weight. Treatment will be for 96 weeks.
Interventions
Hydroxychloroquine is classified as an anti-malarial and it is has immunomodulatory functions that make it useful for treatment of autoimmune disorders including systemic lupus erythematosus and rheumatoid arthritis.
An oral capsule placebo is made to match the active intervention medication hydroxychloroquine.
Eligibility Criteria
You may qualify if:
- Between 15 and 49 years of age, inclusive, at Visit 1.
- Anti-nuclear antibody (ANA) titer of 1:80, or greater, as determined by immunofluorescence assay (IFA).
- Participants must have at least one (but not three or more) additional clinical or laboratory criterion from the 2012 Systemic Lupus International Collaborating Clinics (SLICC) classification criteria.
- Written informed consent (and assent when applicable) obtained from subject or subject's legal representative and ability for subject to comply with the requirements of the study.
You may not qualify if:
- The subject meets the 2012 SLICC classification criteria for SLE at Visit 1 (i.e., ANA plus 3 other criteria, or ANA plus biopsy-proven lupus nephritis).
- The subject has been diagnosed with another autoimmune disorder, other than autoimmune thyroid conditions.
- The subject has fibromyalgia, based on clinical history and exam.
- The subject has previously been or is currently being treated with oral antimalarial agents including hydroxychloroquine, chloroquine, or quinacrine.
- The subject is currently or has been treated with immunosuppressive, immune modifying, or cytotoxic medications as listed in Section 7.2.
- Use of any investigational agent within the preceding 12 months.
- History of primary immunodeficiency.
- Active bacterial, viral, fungal, or opportunistic infection.
- Evidence of infection with human immunodeficiency virus (HIV), Hepatitis B, or Hepatitis C.
- Concomitant malignancy or history of malignancy with the exception of adequately treated basal or squamous cell carcinoma of the skin, or carcinoma in situ of the cervix.
- The subject has significant findings on ophthalmological examination that, in the opinion of the examining Ophthalmologist, prevent safe use of hydroxychloroquine.
- The subject has other contraindications to treatment with hydroxychloroquine including pre-existing ocular disease, hepatic impairment, psoriasis, porphyria, or allergy to the drug or class.
- Co-morbidities requiring systemic corticosteroid therapy greater than 10 mg of prednisone per day, or equivalent, or a change in corticosteroid dose within the 3 months prior to Visit 1.
- Starting, stopping, or changing the dose of over the counter or prescription non-steroidal anti-inflammatory drugs (NSAIDs) in the three months prior to Visit 1.
- Pregnant, breastfeeding, or unwilling to practice birth control during participation in the study.
