- Evidence of active infection unless the medical monitor and investigator agreed that the participant was appropriate for this study
- History of rheumatoid arthritis or systemic lupus erythematosus (SLE) (History of osteoarthritis or gout did not exclude participants from eligibility in the study.)
- Age-related macular degeneration (AMD), diabetic macular edema or active diabetic proliferative retinopathy that was likely to require treatment during the trial

- Intravenous iron supplementation within the past 21 days
- Currently taking acetaminophen \> 2.6 grams/day
- History of prior organ transplantation, or stem cell or bone marrow transplantation
- Alcohol consumption greater than 14 or more drinks per week within the past year (1 drink = 12 ounce \[oz\] beer, 5 oz wine, or 1.5 oz hard liquor.)
