Phase I Study Of The Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Of Multiple Intravenously Administered Doses Of PF-04236921 In Patients With Rheumatoid Arthritis

This study has been completed.
Information provided by (Responsible Party):
Pfizer Identifier:
First received: February 4, 2009
Last updated: March 28, 2012
Last verified: March 2012
This study will evaluate the safety and tolerability of PF-04236921 administered monthly as three intravenous infusions. Each group of patients will be assigned to a dose level; Safety and tolerability of a low dose level will be required before proceeding to successively higher dose levels. Blood tests will be performed to measure the amount of drug and changes in measures of inflammation.
