Safety of and Immune Response to a Human Parainfluenza Virus Vaccine (rHPIV3cp45) in Healthy Infants
Phase 1 Study to Determine the Safety, Infectivity, and Tolerability of Two Doses of Live Attenuated Recombinant Cold Passaged (cp) 45 Parainfluenza Type 3 Virus Vaccine, rHPIV3cp45, Lot PIV3 102A, Delivered as Nose Drops to Infants 6 to 12 Months of Age, and to HPIV3 Seronegative Infants and Children 6 to 36 Months of Age

Detailed Description
HPIV type 3 (HPIV3) ranks second only to respiratory syncytial virus as the most important cause of bronchiolitis and pneumonia in infants less than 6 months of age. HPIV3 can cause severe disease in the first 2 years of life and is responsible for 11% of hospitalizations for respiratory diseases in children. This study will evaluate the safety and immunogenicity of a live recombinant attenuated intranasal HPIV3 vaccine, rHPIV3cp45.
This study will last for a maximum of 180 days. Infants will be enrolled into one of two study groups, Group 1 or Group 2. Depending on the study location, groups will enroll either sequentially or concurrently. Within each group, infants will be randomly assigned to receive 2 immunizations of rHPIV3cp45 or placebo. Immunizations will be given as nose drops. Immunizations will be given at study entry and approximately 4 to 10 weeks after study entry.
On the day of immunization, a physical exam, vital signs measurement, blood collection, and medical history will occur. Infants will be observed for 15 minutes after immunization for any immediate adverse effects. Parents or guardians will be given a thermometer to take with them and will be instructed on how to take their infant's temperature. They will be given the study schedule and will need to provide contact phone numbers so study personnel can contact them by phone during the days after immunization. Parents and guardians will be contacted by telephone on days without study visits, from Day 1 to Day 19 and on Day 180 after immunization, and asked about any illnesses or adverse effects they have observed in their immunized infants.
Parents or guardians will need to record their infant's temperature daily for at least the 17 days immediately following immunization. During this 17-day period, there will be at least 6 study visits associated with each immunization; visits will occur on the day of immunization and approximately 3, 7, 10, 14, and 17 days after immunization. At all study visits, infants will undergo a physical exam and vital signs measurement. Group 1 participants will also undergo a nasal wash for a viral culture. There will be additional follow-up visits occurring sometime between 28 and 70 days after the first dose and 28 to 35 days after the second dose; blood collection will occur at the follow-up visits. Additional visits may be required on selected days during the month after immunization. Infants who experience illness or side effects may be asked to return to the clinic for examination. Parents or guardians will be made aware of whether their infant received the HPIV vaccine or placebo 18 days after the second immunization or in the event of a lower respiratory tract illness.
