Eligibility Criteria
INCLUSION CRITERIA Male and female outpatients between 18 and 75 years of age Females must be of non-childbearing potential (post-menopausal, surgically sterilized or post hysterectomy) or using a double-barrier method of birth control for the duration of the study. A protocol acceptable method of double barrier method of birth control includes any combination of two or three of the following: condom, spermicidal and diaphragm. Documented diagnosis of rheumatoid arthritis of at least six (6) months duration, as defined by the American Rheumatism Association 1987 Revised Criteria American Rheumatism Association Functional Class I, II, or III Meet the criteria for (active disease) at both screening and baseline visits by achieving all of the criteria below: 6 or more painful/tender joints 6 or more swollen joints Visual Analog Scale (VAS) for pain of at least 3 (on scale of 1-10, where 1 is mild) C-reactive protein (CRP) greater than or equal to 0.6 mg/dl or ESR greater than 25 mm/hr. Prior/Current Therapy: A. Subjects must be either DMARD or biological anti-RA agent naive or have failed a DMARD/biological RA agent, other than sulfasalazine, and have stopped this DMARD/biological one (1) month prior to randomization unless they have a flare in disease activity upon discontinuing DMARD/biological therapy as part of this protocol. DMARDs include but are not limited to methotrexate, leflunomide, minocycline, hydroxychloroquine, gold, cyclosporine, and biologics include anti-TNF and anti-IL-1 agents. B. Subjects may be taking NSAIDs, provided the dose and frequency have been stable for 30 days prior to randomization. However if the patient meets the flare criteria they can be enrolled even if they have not fulfilled the criteria of being on a stable dose of NSAIDs and steroids for 30 days prior to randomization. At the time of flare neither steroids nor NSAIDs can be increased. C. Subjects may be taking corticosteroid therapy equivalent to prednisone less than or equal to 7.5 mg/day. This dose must be stable for at least 1 month prior to randomization. Subjects may not change the dose of their corticosteroid or receive intra-articular or intra-muscular injections of corticosteroids, within 1 month of randomization or during the study. Note section 9.3 of the protocol, Concomitant Medication, has been amended to read: If it is medically necessary a one joint steroid injection is acceptable. This must be noted on the CRF and the joint excluded from the joint count. D. Subjects may not be taking other complementary and/or alternative medications for RA for the last 1-month prior to randomization. Subjects must provide written informed consent prior to any study-related screening tests. EXCLUSION CRITERIA Subjects with RA for less than six months duration, or onset before age 16 (JRA) Clinically significant, uncontrolled concurrent neurological, hematological, renal, hepatic, endocrine, pulmonary, or cardiovascular disease Subjects with evidence of an active clinically important cardiovascular disease as evidenced by an ECG at screening Concomitant therapy or therapy within the last 30 days with another investigational drug Subjects with screening laboratory values that deviate from the upper or lower limits of normal by greater that the percentages listed below: Liver function tests: Total bilirubin above the upper limit of normal (ULN). AST, ALT, 1.5 X greater than ULN Hematology: Total white blood count (WBC) less than 3500mm3. Hemoglobin and hematocrit less than 10 g/dl or 30%, unless stable for at least 3 months), and platelet count less than 100K or greater than 750 K. Renal function tests: BUN or creatinine greater than 1.2 X above the ULN Urinalysis: On dipstick - Proteinuria / hematuria / leukocytes greater than trace. Subjects with serological evidence of chronic hepatitis B (positive HbsAG) or hepatitis C (positive C Ab), HIV Subjects with evidence of active peptic ulcer disease or who have a reliable positive history of gastrointestinal bleeding within the past five (5) years. Any recurrent or history of an intestinal disorder that may interfere with the proper absorption of the drug Pregnant women or nursing mothers Subjects who plan to donate blood or blood products during the study or within 30 days following the last study visit. One re-screening to meet criterion 6.1.5 will be allowed. Multiple screenings, beyond one for failure to meet criterion 6.1.5 are not allowed (at either screening or baseline). Abuse of alcohol or drugs. The subject should not consume more than 2 units of alcohol per day. (A unit of alcohol is considered: 12 oz of beer, 6 oz of wine or 1 oz of spirits). This is on a per day basis and not the average for the week. Subjects with a sulfonamide allergy Subjects who have known G6PD deficiency Subjects who are unable or unwilling to follow the protocol Recent major trauma or major surgery or serious infection Subjects who started but left, or were dropped out of this study, for any reason (subjects who left or are dropped will not be replaced).
