The purpose of this study is to determine if hydroxychloroquine (HCQ) is safe and effective for the prevention of future onset of rheumatoid arthritis (RA) in individuals who have elevations of an autoantibody, anti-cyclic citrullinated peptide (anti-CCP3).
The following recruitment strategies will be employed towards identifying healthy subjects with elevated anti-cyclic citrullinated peptide (anti-CCP3) levels:
-Pre-screening:
- first degree relatives of patients with rheumatoid arthritis (RA);
- subjects at health-fairs; and
- identification of subjects with elevated anti-CCP3 levels in the absence of inflammatory arthritis in rheumatology clinics.

Healthy Participants Rheumatoid Arthritis (RA) Prevention | Drug: Hydroxychloroquine Drug: HCQ Placebo | Phase 2 |
Rheumatoid arthritis (RA) affects an estimated 1% of the population. RA is a disease where the immune system attacks the joints, leading to joint inflammation and damage that is felt by someone with RA as joint pain, stiffness and swelling.
Recent studies have shown that there are markers in the blood called 'autoantibodies' that precede the onset of joint symptoms of RA. Antibodies are commonly made in the blood to fight infections. Sometimes, these antibodies attack one's own body. These are called autoantibodies.
Certain autoantibodies are specific for certain diseases. The autoantibody known as anti-CCP3 is specific for RA and can predict the development of RA in the future, especially if the level of anti-CCP3 is high. The investigators of this study believe that individuals with elevations of anti-CCP3 ≥2 times the normal value have approximately a 50% chance of developing RA within 3 years.
Hydroxychloroquine (HCQ) is already used successfully and safely in the treatment of malaria, lupus and RA. The objective of this study is to determine whether treatment with HCQ in individuals with elevations of anti-CCP3 without joint inflammation may help prevent the future onset of RA. This will involve a 12-month course of HCQ in the prevention of the development of clinically apparent RA at 36 months in individuals at high-risk for future RA due to high titer elevations of anti-CCP3. This study will recruit for individuals without a history or clinical findings of inflammatory arthritis. Eligible subjects will be randomized in a 1:1 ratio to HCQ versus HCQ placebo.

- Number of Participants Who Developed Clinically-Apparent Rheumatoid Arthritis (RA) From Treatment Initiation to Month 12 By Treatment Arm [ Time Frame: Up to Month 12 ]Clinically-Apparent RA is defined by the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) Classification Criteria as either: 1.) a score of ≥ 6 defining "definite RA" or 2.) a joint examination consistent with IA with ≥ 1 erosion confirmed by x-ray imaging of the hands, wrists, and feet.
- Number of Participants Who Developed Inflammatory Arthritis (IA) From Treatment Initiation to Month 12 by Treatment Arm [ Time Frame: Up to Month 12 ]IA is defined as the development of swollen joint(s) consistent with RA-like synovitis. The joint exams conducted by a physician at each clinic visit were used to identify the presence of swollen joints due to IA.
- Median Time to Development of Clinically-Apparent Rheumatoid Arthritis (RA) By Treatment Arm [ Time Frame: Up to Month 36 ]Median Time from treatment initiation until development of Clinically-Apparent RA. Clinically-Apparent RA is defined by the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) Classification Criteria as either: 1.) a score of ≥ 6 defining "definite RA" or 2.) a joint examination consistent with IA with ≥ 1 erosion confirmed by x-ray imaging of the hands, wrists, and feet.
- Number of Participants Who Developed Inflammatory Arthritis (IA) From Treatment Initiation to Month 36 by Treatment Arm [ Time Frame: Up to Month 36 ]IA is defined as the development of swollen joint(s) consistent with RA-like synovitis. The joint exams conducted by a physician at each clinic visit were used to identify the presence of swollen joints due to IA.
- Number of Participant Self-Reported Painful Joints By Treatment Arm [ Time Frame: At Week 52 and Month 36/End of Study ]The Participant Self-Reported Joint Symptoms assessment was used by participants to indicate which joints were painful on the day of the visit or in the past week. The Participant Self-Reported Joint Symptoms assessment contained a diagram of the body joints which participants used to mark their painful joints.
- Number of Participant Self-Reported Stiff Joints By Treatment Arm [ Time Frame: At Week 52 and Month 36/End of Study ]The Participant Self-Reported Joint Symptoms assessment was used by participants to indicate which joints were stiff on the day of the visit or in the past week. The Participant Self-Reported Joint Symptoms assessment contained a diagram of the body joints which participants used to mark their stiff joints.
- Number of Participant Self-Reported Swollen Joints By Treatment Arm [ Time Frame: At Week 52 and Month 36/End of Study ]The Participant Self-Reported Joint Symptoms assessment was used by participants to indicate which joints were swollen on the day of the visit or in the past week. The Participant Self-Reported Joint Symptoms assessment contained a diagram of the body joints which participants used to mark their swollen joints.
- Number of Participant Self-Reported Painful Joints in the Hands, Wrists and Feet By Treatment Arm [ Time Frame: At Week 52 and Month 36/End of Study ]The Participant Self-Reported Joint Symptoms assessment was used by participants to indicate which joints were painful on the day of the visit or in the past week. The Participant Self-Reported Joint Symptoms assessment contained a diagram of the body joints which participants used to mark their painful joints.
- Number of Participant Self-Reported Stiff Joints in the Hands, Wrists and Feet By Treatment Arm [ Time Frame: At Week 52 and Month 36/End of Study ]The Participant Self-Reported Joint Symptoms assessment was used by participants to indicate which joints were stiff on the day of the visit or in the past week. The Participant Self-Reported Joint Symptoms assessment contained a diagram of the body joints which participants used to mark their stiff joints.
- Number of Participant Self-Reported Swollen Joints in the Hands, Wrists and Feet By Treatment Arm [ Time Frame: At Week 52 and Month 36/End of Study ]The Participant Self-Reported Joint Symptoms assessment was used by participants to indicate which joints were swollen on the day of the visit or in the past week.

- Median Level of Anti-Cyclic Citrullinated Peptide-3 (Anti-CCP3) By Treatment Arm [ Time Frame: Baseline, Week 24, Week 52 (End of Treatment), Month 18, Month 24, Month 36/End of Study ]Anti-CCP3 is a laboratory test in serum for the presence of antibodies to citrullinated protein antigens (ACPAs). ACPA positivity assists with the classification/diagnosis of Rheumatoid Arthritis (RA) of a patient with Inflammatory Arthritis (IA). In addition, determining autoantibody positivity helps with the prediction of RA disease severity. Anti-CCP3 positivity at any level, and in particular anti-CCP3 levels of ≥2 times the normal cut-off level (or ≥ 40 units) are highly predictive of future RA development.
- Median Level of Immunoglobulin M - Rheumatoid Factor (IgM-RF) By Treatment Arm [ Time Frame: Baseline, Week 24, Week 52 (End of Treatment), Month 18, Month 24, Month 36/End of Study ]IgM-RF is a laboratory test in serum for the presence of antibodies to RF. IgM-RF positivity assists with the classification/diagnosis of Rheumatoid Arthritis (RA) of a patient with Inflammatory Arthritis (IA). In addition, determining autoantibody positivity helps with the prediction of RA disease severity. Higher levels of antibodies (e.g. >2-3 times the normal cut-off values) have greater specificity for RA disease.
- Median Level of High-Sensitivity C-Reactive Protein (hsCRP) Treatment Arm [ Time Frame: Baseline, Week 24, Week 52 (End of Treatment), Month 18, Month 24, Month 36/End of Study ]HsCRP is a laboratory test in serum for the presence of CRP. HsCRP is used to detect systemic inflammation in the body, assists with the classification/diagnosis of Rheumatoid Arthritis (RA), and elevations of hsCRP in patients with RA have been associated with poor disease outcomes.
- Percent of Participants Experiencing Grade 3 or Higher Adverse Events (AEs) [ Time Frame: Treatment Initiation (Day 0) through Month 36 ]Adverse Events (AEs) grading will be defined by the National Cancer Institute (NCI) - Common Terminology Criteria for Adverse Events (CTCAE), version 4.0. The number of AEs will be identified by monitoring participant-reported AEs, vital signs, medical history, physical exams and blood safety tests.
