Details and patient eligibility

About

100 Russian children of 2 years of age and less in high-risk populations (preterm, and/or with heart and lung problems) will receive palivizumab (Synagis) 15 mg/kg intramuscularly as prophylaxis to severe respiratory syncytial virus (RSV) infection in order to study the safety and efficacy of the drug in Russian subjects.

Full description

A prospective, multicenter, open-label, non-comparative study of safety and efficacy of palivizumab (Synagis) 15 mg/kg intramuscularly as prophylaxis to severe lower respiratory tract respiratory syncytial virus infection in 100 Russian children of 2 years of age and less in high-risk populations (preterm infants [less than or equal to 35 weeks gestational age], infants with bronchopulmonary dysplasia [BPD], and infants with hemodynamically significant congenital heart disease [HSCHD]).

Enrollment: 100 patients

Sex: All

Ages: Under 2 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Subjects must meet all of the following criteria to be enrolled into the study:

1. Infants at high risk of severe RSV infection defined as fulfilling at least one of the following:

   • Infants born at less than or equal to 35 weeks gestational age AND are less than or equal to 6 months of age at enrollment
   • Infants less than or equal to 24 months of age at enrollment AND with a diagnosis of bronchopulmonary dysplasia (defined as oxygen requirement at a corrected gestational age of 36 weeks) requiring intervention/management (i.e., oxygen, diuretics, bronchodilators, corticosteroids, etc.) anytime within 6 months prior to enrollment
   • Infants less than or equal to 24 months of age at enrollment with hemodynamically significant congenital heart disease, either cyanotic or acyanotic, unoperated or partially corrected. Children with acyanotic cardiac lesions must have pulmonary hypertension (greater than or equal to 40 mmHg measured pressure in the pulmonary artery [ultrasound acceptable]) or the need for daily medication to manage congenital heart disease. Children with the following conditions are not eligible: hemodynamically insignificant small atrial or ventricular septal defects, patent ductus arteriosis, children with aortic stenosis, pulmonic stenosis, or coarctation of the aorta alone.

2. Informed Consent Form signed by parent(s).

Exclusion criteria

Subjects meeting any of the following criteria are not eligible for the study:

1. Hospitalization at the time of enrollment (unless discharge is anticipated within 14 days).
2. Mechanical ventilation (including continuous positive airway pressure [CPAP]) at the time of enrollment.
3. Life expectancy less than 6 months.
4. Active respiratory illness, or other acute infection.
5. Known renal impairment, as determined by the investigator.
6. Known hepatic impairment, as determined by the investigator.
7. History of seizures (except neonatal seizures).
8. Unstable neurological disorder (includes, but is not restricted to, epilepsy and decompensated hydrocephaly).
9. Known immunodeficiency, as determined by the investigator.
10. Allergy to immunoglobulin products.
11. Prior receipt of RSV vaccine or prophylaxis (e.g., palivizumab or motavizumab), or administration of a product possibly containing RSV-neutralizing antibody within 100 days prior to enrollment (includes, but is not restricted to, the following: RSV hyperimmunoglobulin, polyclonal intravenous immunoglobulin, cytomegalovirus hyperimmunoglobulin, varicella zoster hyperimmunoglobulin).
12. Participation in another clinical trial within 30 days prior to enrollment.
13. Previous enrollment in this trial.
14. For any reason, subject is considered by the investigator to be an unsuitable candidate for this study.
