Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
A randomized, double-blind, placebo controlled, Phase I study with 33 sero-susceptible individuals aged 18 to 45 years.

A total of 33 healthy individuals will be enrolled and randomized into 2 groups where each participant will receive a single dose of either CodaVax-H1N1, or placebo (22:11). Participants will receive one 0.1ml into both nostrils (one immediately after the other).

Twenty-two (22) participants will be administered CodaVax-H1N1 and 11 participants will be administered a placebo. All subjects will receive an intranasal (IN) dose of either CodaVax-H1N1, or saline (placebo).

Arm 1: Intranasal dose of CodaVax-H1N1
Arm 2: Intranasal dose of Placebo (Saline)

CodaVax-H1N1 is a potential universal live attenuated influenza vaccine (LAIV) manufactured using a proprietary SAVE platform based on the H1N1 A/California/07/2009 (H1N1) strain. The vaccination dose will be 8 x 10^5 PFU in 200 microlitre of current Good Manufacturing Practice (cGMP) Dulbecco Modified Eagle Medium media and 7.5% sucrose, and is to be administered through an intranasal sprayer into one or both nostrils.

As the CodaVax-H1N1 dose is 8-times higher than the highest dose administered in the first clinical trial (UTN: U1111-1191-3515), the first 3 participants dosed with CodaVax-H1N1 will be sentinel participants. These participants will be monitored for 60 to 90 minutes immediately following dosing on Day 0 (visit 3), and return for testing on Day 2 (visit 3) and Day 6 (visit 4). If dosing of the sentinels proceeds without clinically significant adverse events (AEs) over 7 days, all remaining participants will be dosed.

Following vaccination all participants (CodaVax, and placebo) will be monitored at the clinic for at least 60-90 minutes following vaccination, after which they will return to the clinic (Day 2 and 6) to be monitored until Day 6 post-vaccination and on Day 30 post-vaccination for a Follow-up visit.

A soft-lock will be placed on the database after the Day 30 Follow-up visits are complete, at which point the data will be unblinded and an interim preliminary report will be written.

All participants will then receive an open-label Close-out phone interview 6 months post-vaccination and a final clinical study report will be written.

Outcomes
Primary outcome [1] 308304 0
The primary outcome of this study is the assessment of the safety profile and tolerability of CodaVax-H1N1 influenza vaccine compared to placebo controls when administered to healthy adults. This is a composite primary outcome and will be tested by clinical laboratory testing, physical examination, vital sign assessments, noting the frequency and types of adverse events. The expected adverse events related to influenza vaccines are runny nose, nasal congestion, sore throat, chills, loss of appetite, shivers, fatigue, headache, sweating, muscle pain, vomiting, diarrhoea, chest pain, shortness of breath, joint pain. The participant will be asked to record these on a diary for 6 days after the day of dosing and the site staff will also specifically query for these at each visit

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
The data sharing statement was marked 'No' with the reason being that this is a healthy volunteer study and the individual participant results are not useful to the participants or to others outside of the Sponsor.
