About this study

Official title: Phase I Study to Determine the Safety, Infectivity, and Tolerability of 2 Doses of Live Attenuated Recombinant Cold-Passaged (cp) 45 Human Parainfluenza Type 3 Virus Vaccine, rHPIV3cp45, Lot PIV3#102A, Delivered as Nose Drops to HPIV3-Seronegative Infants and Children 6 to 36 Months of Age, at a 6 Month Interval

Human parainfluenza viruses (HPIVs) are a major health concern in infants and young children under 5 years of age, causing serious respiratory tract disease. The primary purpose of this study is to test the safety of and immune response to a new HPIV vaccine in healthy infants and children.

Read the 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 approximately 28 weeks. Infants and children 6 months to 36 months of age will be randomly assigned to one of two groups. Group 1 participants will receive 2 immunizations of rHPIV3cp45. Group 2 participants will receive 2 doses of rHPIV3cp45 placebo. Immunizations will be given as nose drops and administered at study entry and approximately 22 to 27 weeks after study entry.

On the day of immunization, a physical exam and blood collection will occur. Participants 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 child'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 daily from Day 1 to Day 18 after each immunization.

Parents or guardians will need to record their child's temperature daily for at least 17 days immediately following immunization. During this 17-day period, study visits will occur on Days 3, 6, and 12 after each dose of vaccine or placebo. Participants will undergo a nasal wash for a viral culture at all study visits. There will be additional follow-up visits occurring sometime between 49 and 63 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing rHPIV3cp45 in people with Paramyxoviridae Infections and Virus Diseases, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Frequency of vaccine-related reactogenicity events and other adverse events (time frame: Throughout study). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01021397, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jan 2013.
