E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to describe the safety and tolerability of MEDI-524 when given monthly as prophylaxis against serious RSV infection among children with hemodynamically significant CHD. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are: 1. To describe the pharmacokinetics and immunogenicity of MEDI-524 2. To describe the RSV hospitalization rates in children with hemodynamically significant CHD given MEDI-524 or palivizumab for prophylaxis against serious RSV disease 3. To describe the effect of cardiopulmonary bypass on serum MEDI-524 concentrations |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Children must meet all of the following criteria: 1. 24 months of age or younger at randomization (child must be randomized on or before their 24-month birthday) 2. Documented, hemodynamically significant CHD. Note: The following children are not eligible: children with uncomplicated small atrial or ventricular septal defects or patent ductus arteriosus, children with aortic stenosis, pulmonic stenosis, or coarctation of the aorta alone. Children with acyanotic cardiac lesions must have pulmonary hypertension (≥ 40 mmHg measured pressure in the PA) or the need for daily medication to manage CHD. 3. Unoperated or partially corrected CHD 4. Written informed consent obtained from the patient’s parent(s) or legal guardian |
|
E.4 | Principal exclusion criteria |
Children must have none of the following: 1. Unstable cardiac or respiratory status, including cardiac defects so severe that survival is not expected or for which cardiac transplantation is planned or anticipated 2. Hospitalization, unless discharge is anticipated within 21 days 3. Anticipated cardiac surgery within two weeks of randomization 4. Requirement for mechanical ventilation, extracorporeal membrane oxygenation, continuous positive airway pressure or other mechanical respiratory or cardiac support 5. Associated non-cardiac anomalies or end organ dysfunction resulting in anticipated survival of less than six months or unstable abnormalities of end organ function 6. Acute respiratory or other acute infection or illness. Note: children with any respiratory symptoms must have a negative RSV test prior to randomization. 7. Chronic seizure or evolving or unstable neurologic disorder 8. Known immunodeficiency 9. Mother with HIV infection (unless the child has been proven to be not infected) 10. Known allergy to Ig products 11. Receipt of palivizumab, RSV-IGIV, or other RSV-specific monoclonal antibody, or any other polyclonal antibody (for example, Hepatitis B IG, IVIG, VZIG) within 3 months prior to randomization 12. Use of investigational agents within the past three months (other than investigational agents commonly used during cardiac surgery or the immediate post-operative period, e.g., nitric oxide) 13. Current participation in other investigational protocols of drugs or biological agents |

E.5 End points |
E.5.1 | Primary end point(s) |
Safety and tolerability of MEDI-524 will be assessed primarily by summarizing adverse events occurring through Study Day 150, including the occurrence of increased toxicity grade from baseline as determined in laboratory evaluations. Adverse and serious adverse events will be summarized by system organ class and preferred term, severity, and relationship to study drug. Cardiac surgical events (elective, sooner than planned, associated with deaths) will also be summarized. |
