• Patients who completed Studies C-788-010 or C-788-011 and did not withdraw due to adverse events
• Patients who withdrew from Study C-788-010 at Month 4 or Month 5 because of a pre-defined lack of efficacy
• Females of childbearing potential must be fully informed of the potential for R788 to adversely affect the fetus and, if sexually active, must agree to use a well established method of birth control during the study (oral contraceptive, mechanical barrier, long acting hormonal agent). These patients must not be lactating and must have a negative pregnancy test at the time of entry and at each laboratory determination.

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. Specifically, excluded are patients with the following:

  1. unresolved Grade 2 or greater toxicity in a RA protocol studying R788
  2. uncontrolled or poorly controlled hypertension;
  3. recent (within past 2 months) serious surgery or infectious disease;
  4. recent history (since enrollment in prior R788 study) of, or treatment for, a malignancy other than non-melanomatous skin cancer, or any history of lymphoma;
  5. known to be positive for Hepatitis B, Hepatitis C, HIV or Tuberculosis;
  6. interstitial pneumonitis or active pulmonary infection;
  7. known laboratory abnormalities: ALT > 1.2 x ULN, creatinine >1.5x ULN, an ANC <2,500/mm3 or 2.5 x 109/L, lymphocyte count < 600/mm3 or 0.6 x 109L, Hgb < 9 g/dL or 5 mmol/L, platelet count <125,000/mm3 or 125 x 109/L are excluded.
• The patient has a history of substance abuse, drug addiction or alcoholism. Patients may consume up to 4 units of alcohol per week; however, alcohol should be avoided in the 72 hours prior to lab assessments. Patients who cannot reliably comply with this should be excluded.
