EZ-2053 in the Prophylaxis of Acute Pulmonary Allograft Rejection

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00105183

Brief Summary:
The purpose of this study is to assess the efficacy and safety of the study drug, known as "ATG Fresenius S," which is sometimes called "EZ-2053," to prevent a lung transplant patient's body from rejecting a transplanted lung or lungs.

Condition or disease Intervention/treatment Phase
Chronic Obstructive Pulmonary Idiopathic Pulmonary Fibrosis Cystic Fibrosis Bronchiectasis Pulmonary Vascular Disease Biological: Placebo Biological: EZ-2053 Biological: EZ-2053 5mg/kg Phase 3

Detailed Description:
Patients are generally consented for the study once they go on the lung transplant waiting list and then are re-consented periodically thereafter until they undergo the lung transplant surgery. A pre-surgical assessment consisting of medical history, physical exam, ECG, chest X-Ray, and blood tests are conducted. After lung transplant surgery, patients are assessed for continued eligibility. Within 6-24 hours after the end of surgery, patients are randomized to receive one infusion of study drug or placebo through a central venous catheter. Each day for 5 days following transplant surgery, patients are monitored for transplant rejection, infections, adverse events and laboratory test changes. On post-randomization Days 14, 30, 60, 90, 180, 270 and 365, patients will be monitored for acute transplant rejection, infections and cancer, pulmonary function tests and adverse experiences. Pulmonary biopsies will be performed on post-randomization Days 30, 60, 90, 180 and 365. Blood samples will be drawn during each visit.
