About this study

Official title: A Phase I Randomized, Observer-blind, Controlled, Dose Escalation Trial of the Safety and Tolerability of a Single Intramuscular Dose of a PAL Adjuvant (FB-631) Co-administered With Seasonal TIV (2013-2014) in Healthy Adults.

This is a phase 1, research study is looking at the safety and acceptability of a new vaccine adjuvant (immune booster) called PAL when combined with the seasonal flu vaccine (Fluviral) to test the safety and effectiveness of new vaccines and medications on healthy volunteers.

The study will enroll approximately 48 healthy adult participants, and occur over 3 years. In the first six months/180 days of the study participants will have visits to the study site during which safety and immunogenicity outcomes will be measured. From Day 181 to Year 3, participants will be contacted by telephone or email to collect information on any adverse events.

Read the detailed description

This is a phase 1, dose-ranging, randomized (5:1), observer-blind, controlled study of the safety and immune response to intramuscular injection of PapMV (Papaya Mosaic Virus) rVLP (Recombinant Virus-Like Particles) which is PAL adjuvant, or "PAL" combined with Trivalent Influenza Vaccines (TIV) at one of four dose levels of PAL, combined with one of two dose levels of TIV, or active control (TIV). The study will enroll approximately 48 healthy adult participants, and occur over 3 years. In the first six months/180 days (Epoch 1) of the study participants will have visits to the study site during which safety and immunogenicity outcomes will be measured. In Epoch 2 (Day 181 to Year 3) participants will be contacted by telephone or email to collect unsolicited adverse events.

This is a controlled clinical trial. The control group will receive the standard dose of TIV, 0.5 mL, which consists of 15 μg haemagglutinin (HA) of each influenza strain recommended by the World Health Organization (WHO) for the 2013-2014 influenza season in the northern hemisphere. An active control is used so that the attributable risk of adverse events can be estimated, and so that outcome measures can be assessed in a blinded fashion. Only adults in stable health will be eligible in order to minimize participant risk. Only non-pregnant females of childbearing age are eligible, and they must agree to continue adequate contraception for 180 days after injection. Study holding rules and a safety evaluation by a Safety Review Committee (SRC) will be in place. The study will follow a staggered dose-escalation design, with each of four steps introducing a new dose of the adjuvant (30, 60, 120 and 240 μg respectively).

The first dose level of PAL adjuvant FB-631 is 0.5 X 60 µg (i.e., 30 µg), which is half the dose that was found to be most immunogenic in animal studies. The adjuvant is co-administered with 0.25 mL of TIV, which is half the dose of TIV that is routinely administered to adults (i.e. 7.5 μg of each of the three influenza subtypes contained in the vaccine). The next dose level is 60µg of FB-631 combined with 0.25 mL TIV. The third dose level is 120 μg of FB-631 with 0.25 mL TIV. In the fourth and final step the dose of adjuvant is 240 μg of PAL adjuvant combined with 0.25 mL TIV (8 participants) or 0.125 mL TIV (i.e. 3.75 μg HA of each influenza subtype contained in the vaccine) (8 participants).

Any safety signal observed in the study will lead to a hold until the decision of Safety Review Committee to continue, modify or suspend the conduct of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PAL and TIV in people with Flu, run by Folia Biotech Inc. at 1 site in Canada.

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 3 inclusion and 13 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: status not confirmed, as of the sponsor's last update on 12 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. 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. 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?

Results are not available in the source record.

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: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 12 Feb 2016.
