Influenza Clinical Trial
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.
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. ;
