  • Access to a consistent means of telephone contact.
  • Comprehension of the study requirements, ability to comprehend and comply with procedures for collection of short- and long-term safety data, expressed availability for the required study period, and ability and willingness to attend scheduled visits.
  • Subjects who the investigator believes that they can and will comply with the requirements of the protocol should be enrolled in the study

Who cannot join

  • Presence of evidence of substance abuse or of neurological or psychiatric diagnoses which, even if clinically stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
  • Diagnosed with cancer, or treatment for cancer, within 3 years.
  • Persons with a history of cancer who are disease-free without treatment for 3 years or more are eligible.
  • Persons with a history of histologically-confirmed basal cell carcinoma of the skin successfully treated with local excision only are excepted and may be enrolled, but other histological types of skin cancer are exclusionary.
  • Women who are disease-free 3 years or more after treatment for breast cancer and receiving long-term prophylactic tamoxifen are excepted and may be enrolled.

  • Any significant disorder of coagulation or treatment with Coumadin derivatives or heparin.
  • Administration of any vaccines within 30 days before study enrollment or during the 30 days following the last test article dose. Subjects who receive such immunizations on an emergent basis after enrollment will be followed per protocol and included in the Total Vaccinated Cohort (TVC), but excluded from the According to Protocol (ATP) Cohort for both safety and immunogenicity.
  • Previous administration of any H5N1 vaccine.
  • Use of any investigational or non-registered product (drug or vaccine) or planned participation in another investigational study within 30 days prior to study enrollment, or during the 182 days following the first test article dose.

  • Known pregnancy or a positive urine beta-human chorionic gonadotropin (β-hCG) test result prior to either vaccination.
  • Lactating or nursing.
  • Women of child bearing potential who lack a history of reliable contraceptive practices. The provision of this history does NOT replace the requirement to perform, and obtain negative results in pregnancy urine tests prior to treatments. Note: all women will have urine pregnancy tests regardless of their status.
  • Known receipt of analgesic or antipyretic medication on the day of treatment with specific intent of prophylaxis of vaccine reactogenicity on the day of first or any treatment. Subjects on stable chronic regimens of potentially analgesic or anti-pyretic medications for pre-existing diagnoses are not required to discontinue them

About this study

Official title: A Trial to Evaluate the Immunogenicity of Accelerated Primary Vaccination With Monovalent A/Indonesia/5/05 (H5N1) Vaccine Antigen in Association With AS03 Adjuvant in Adults Aged 18-64

The purpose of the study is to characterize the immunogenicity \& safety of 2 doses of GSK's avian flu vaccine GSK 1557484A given according to different regimens to adults aged 18 to 64 years

Read the detailed description

A Phase 2, open-label, randomized, parallel group, multi-centered study designed to evaluate the immunogenicity and safety of a 2-dose series of avian influenza vaccine plus AS03 adjuvant according to different regimens, in adults aged 18-64 years. All subjects will receive active study vaccine; no subjects are to receive placebo. A total of 312 subjects will be enrolled in this study at approximately 3 study centers in Canada. All subjects will attend formal study center visits for safety and immunogenicity assessments on Days 0, 21, 42, and 182. Additional formal study center visits will be scheduled at additional timepoints for subjects in particular dose groups. In addition, a telephone call will be conducted for all subjects on Day 51

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Influenza A (H5N1) Virus Monovalent Vaccine in people with Influenza, run by GlaxoSmithKline at 3 sites 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 6 inclusion and 18 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 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Feb 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Seroconverted Subjects Against the A/Indonesia/5/2005 (H5N1) Strain of Influenza Disease. (time frame: At Day 14 post Dose 2). The study lists 3 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 NCT00695669, 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 2018.
