ClinicalTrials.gov Identifier:
NCT01239017
First received: November 9, 2010

  Purpose

This is a double-blind, prospective, randomized study in which patients will be randomized to 1 of 5 treatment arms (4 active and 1 placebo).

Each patient will receive one SC injection of REGN475 or placebo and 1 IV infusion of either REGN475 or placebo, on day 1 (baseline) In order to preserve the blind, patients receiving REGN475 SC will also receive placebo IV, and patients receiving REGN475 IV will also receive placebo SC.
