Eligibility Criteria
Inclusion Criteria: Patients must give written informed consent by signing an IRB-approved Informed Consent Form (ICF) prior to admission to this study. Males and females, 18 to 75 years of age, with active RA for at least 12 months (functional class I-III, e.g., not bed or wheelchair-bound) who have been receiving weekly doses of methotrexate (10-25 mg/week) for a minimum of 180 days, and who have been receiving a stable MTX dose of at least 15 mg without any change in route or change in folic acid supplementation for at least 30 days. Active RA is defined as the presence of (a)6 swollen joints (28 joint count); AND (b)6 tender joints (28 joint count); AND (c) CRP level > ULN for the central reference laboratory. Patient may receive up to 10 mg per day of oral prednisone or steroid equivalent, NSAID therapy, hydroxychloroquine, chloroquine, minocycline, sulfasalazine, and doxycycline. The dose(s) must have been stable for at least 30 days and must not be changed during the washout, screening and treatment periods, unless dictated by tolerability requirements. Females of childbearing potential must be fully informed of the potential for methotrexate and R788 to adversely affect the fetus and must agree to use adequate (2 methods) contraception during the study. These patients must not be lactating and must have a negative urine pregnancy test at the time of randomization and at each laboratory determination. The patient is in otherwise good health as determined by the Investigator on the basis of medical history, physical examination, and laboratory screening tests during the screening period, including the absence of clinically significant findings, such as HIV, HBV or HCV, interstitial pneumonitis or active pulmonary infection, on chest X-ray taken within 6 months prior to screening and a negative TB skin test, or abnormal liver function defined as known ALT >1.2xULN within the past 90 days. In the investigator's opinion, the patient has the ability to understand the nature of the study and any hazards of participation, and to communicate satisfactorily with the investigator and to participate in, and to comply with, the requirements of the entire protocol. Exclusion Criteria: The patient has a history of, or a concurrent, clinically significant illness, medical condition (other than arthritis) or laboratory abnormality that, in the Investigator's opinion, could affect the conduct of the study (these will be included in an exclusion log). The patient has a history of substance abuse, drug addiction or alcoholism. The patient is unable to abstain from alcohol during the study. The patient has a recent (past 5 years) history of, or treatment for, a malignancy other than basal skin cancer. The patient has received any investigational medication within 30 days prior to admission to the study. Any patient who has received any of the following treatments must abide by the indicated washout period: oral or injectable gold, azathioprine, penicillamine, anakinra require a 30 day washout period prior to Day 1 dosing cyclosporine, abatacept, etanercept, infliximab or adalimumab require a 60 day washout period prior to Day 1 dosing leflunomide requires a 60 day washout period prior to screening, unless the patient has undergone cholestyramine washout at least 30 days prior to Day 1 dosing cyclophosphamide requires a 180 day washout period prior to Day 1 dosing Rituxan requires a 180 day washout period and normal CD19 count prior to Day 1 dosing parenteral or intra-articular corticosteroids require a 30 day washout period prior to Day 1 dosing Patients with the following laboratory abnormalities: ALT > 1.2X ULN, creatinine > ULN, a neutrophil count < 2,500/mm3 or lymphocyte count < 800/mm3, Hgb < 10 g/dL, platelet count < 125,000/mm3 are excluded. Patients should not use CYP3A4 inhibitors from within 3 days of randomization until the end of study. R406 is metabolized by CYP3A4, and ketoconazole increases the R406 AUC of a dose of R788 by approximately 2 fold. Patients should not use CYP3A4 inducers from within 3 days of randomization until the end of the study. Although glucocorticoids are inducers, a stable dose of no more than 10 mg/day is allowed.
