Description of intervention(s) / exposure
Treatment: Drugs - Maraviroc
Treatment: Drugs - Maraviroc Placebo

Placebo comparator: 2 -

Experimental: 1 - This study was divided into two components: safety/pharmacokinetic (PK) and proof-of-concept (POC). In the safety/PK component either 150 mg or 300 mg tablets of maraviroc was administered twice a day (BID) to 16 rheumatoid arthritis subjects for 4 weeks.


Treatment: Drugs: Maraviroc
300 mg (2- 150 mg tablets) are administered by mouth twice a day (BID) for 12 weeks.

Treatment: Drugs: Maraviroc Placebo
Placebo tablets to match active drug. Two tablets are administered by mouth twice a day (BID) for 12 weeks.
