Brief Summary:
This study will test the safety and tolerability (how the body reacts to the drug) of REGN88 and placebo (an inactive substance that contains no medicine) in patients with Rheumatoid Arthritis.

Condition or disease Intervention/treatment Phase
Rheumatoid Arthritis Biological: REGN88 Phase 1

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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 15 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose Study of the Safety and Tolerability of Subcutaneously Administered REGN88 in Subjects With Rheumatoid Arthritis Receiving Concomitant Methotrexate
Study Start Date : July 2008
