Detailed Description:

This is a multi-center, randomized, double blind, placebo-controlled, single dose escalation study of the safety and tolerability of subcutaneously administered REGN88 in rheumatoid arthritis patients who are receiving concomitant methotrexate.

Three (3) sequential dose cohorts of 5 subjects (4:1 active: placebo) will be dosed SC with REGN88 or placebo. Subjects who complete the study will participate in 14 study visits over 16 weeks.

  4. For women of childbearing potential, a negative serum pregnancy test at the Screening Visit (Visit 1) and a negative urine pregnancy test at Day -1
