About this study

Official title: A Phase I Escalating Dose Ranging Study to Evaluate the Safety and Immunogenicity of the VAX128 A, B, and C Novel H1N1 Influenza Vaccine Constructs in Healthy Adults 18-49 Years of Age and in Community Living Adults ≥65 Years of Age

This is a multicenter, escalating dose-ranging study to assess the safety, reactogenicity and immunogenicity of 3 different novel H1N1 influenza vaccine constructs delivered i.m. as a single dose vaccination on day 0.

Read the detailed description

VAX128-01 is a first in human study of three inactivated recombinant novel H1N1 influenza vaccines, designated VAX128 A, B and C. The purpose of the study is to compare the safety and immunogenicity of the three vaccines through a range of doses and to select one of the vaccines for further testing in phase II studies. We plan to assess the safety and immunogenicity in a dose escalating study. The study will enroll up to 100 healthy young adults (18-49 years) and 100 healthy adults than age 65 years. We are including the older adults in this phase 1 study because we have found that the elderly tolerated a vaccine similar to one of the candidates, VAX128A, better than young adults, but required a higher vaccine dose to achieve a similar antibody response. Nevertheless, because we are testing two other constructs (VAX128B and C), we will be making the conservative assumptions that the safety and immunogenicity data coming from the young adults will not predict the results in the elderly. Therefore, we will begin the study in the young adults and after the first three dose levels have been tested we will begin testing in the older adults. In this study we plan to enroll up to 100 young adults and up to 100 adults 65 years and older. The young adults will be most likely enrolled at one clinical site and the older adults will be enrolled at another clinical site. We plan to enroll a cohort of 10 young adults and 10 older adults every week. Each cohort will consist of 3 subjects to receive one of the three vaccines (9 subjects total) and one subject in each cohort will receive placebo. Dosing for the next cohort will be based on a two day assessment period after vaccination. The main part of the study will be conducted over 28 days and there will be two follow up phone calls at 6 months and one year.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety

    Assess safety, reactogenicity and tolerability. Symptoms will be collected from the memory aid and from the information collected at the clinic visits. All symptoms will be graded according to severity. Response to vaccine will be categorized as local (arm pain, redness, bruising etc) or systemic (headache, muscle aches, fatigue, etc) symptoms. Laboratory tests such as CRP, WBC, LFTs and cytokines collected before and after vaccination will also be analyzed. We will compare the types and severity of symptoms and laboratory results based on vaccine construct or placebo.

    Measured: 28 days

Secondary outcomes (1)
  1. Immunogenicity

    To assess serm immune response, sera collected at Day 0 (pre-vaccination), 7, 14 and 28 will be analyzed for HAI, serum IgG anti-HA by ELISA and serum IgG anti-flagellin by ELISA. The geometric mean, seroconversion and seroprotection rates will be determined.

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VAX128 in people with Influenza, run by VaxInnate Corporation 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 5 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 31 Jul 2012. 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?

Safety (time frame: 28 days). 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 NCT01172054, which also lists 1 linked publication.

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 31 Jul 2012.
