About this study

Official title: A Randomized, Observer-Blinded, Dose-Escalation Phase 1 Study to Assess the Safety and Immunogenicity of Three Different Dose Levels of a Live-Attenuated Chikungunya Virus Vaccine Candidate (VLA1553) in Healthy Volunteers Aged 18 To 45 Years

Randomized, observer-blinded, multicenter, dose-escalation Phase 1 clinical study investigating three dose levels of VLA1553 after a single immunization.

120 study participants will be enrolled into the study to receive three different doses (30 subjects in the low and medium and 60 subjects in the high dose group). Vaccination will be given intramuscularly on Day 0. As safety precaution, the study will begin with enrolment of 20 sentinel subjects in an open-label fashion. Thereafter, subjects will be enrolled in a blinded, randomized manner in the three study arms.

Read more

A re-vaccination will be given at Month 6 or Month 12 to confirm that a single vaccination will be sufficient to induce high titer neutralizing antibodies and protect subjects from CHIKV viremia.

Study participants will be followed up until 13 months after initial vaccination.

What is being measured

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

  1. Frequency of solicited injection site reactions

    Any measurable injection site reaction will be measured by size and includes injection site pain, tenderness, erythema/redness, induration and swelling.

    Measured: up to Day 14 after single vaccination

  2. Severity of solicited injection site reactions

    Any measurable injection site reaction will be measured by size and includes injection site pain, tenderness, erythema/redness, induration and swelling. They will be rated according to the Severity Grading Scale of Injection Site Reactions (FDA Guidance on Toxicity Grading Scales for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (FDA 2007)

    Measured: up to Day 14 after single vaccination

  3. Frequency of solicited systemic reactions

    Systemic reactions including fever, nausea/vomiting, headache, fatigue, myalgia (muscle pain), arthralgia (joint pain) and rash will be reported in a standardized manner

    Measured: up to Day 14 after single vaccination

  4. Severity of solicited systemic reactions

    Systemic reactions including fever, nausea/vomiting, headache, fatigue, myalgia (muscle pain), arthralgia (joint pain) and rash will be reported in a standardized manner. They will be rated according to the FDA Guidance on Toxicity Grading Scales

    Measured: up to Day 14 after single vaccination

Secondary outcomes (8)
  1. Frequency of any adverse event (AE)

    Measured: until Day 14, Day 28 and throughout the study period

  2. Severity of any adverse event (AE)

    The investigator will assess the severity of AEs using his/her clinical expertise and judgment based on the most appropriate description (mild, moderate, severe) as per study protocol

    Measured: until Day 14, Day 28 and throughout the study period

  3. Frequency of solicited injection site reactions

    Any measurable injection site reaction will be measured by size and includes injection site pain, tenderness, erythema/redness, induration and swelling.

    Measured: until Day 14, Day 28 and throughout the study period

  4. Severity of solicited injection site reactions

    Any measurable injection site reaction will be measured by size and includes injection site pain, tenderness, erythema/redness, induration and swelling. They will be rated according to the Severity Grading Scale of Injection Site Reactions (FDA Guidance on Toxicity Grading Scales for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (FDA 2007)

    Measured: until Day 14, Day 28 and throughout the study period

  5. Frequency of solicited systemic reactions

    Systemic reactions including fever, nausea/vomiting, headache, fatigue, myalgia (muscle pain), arthralgia (joint pain) and rash will be reported in a standardized manner

    Measured: until Day 14, Day 28 and throughout the study period

  6. Severity of solicited systemic reactions

    Systemic reactions including fever, nausea/vomiting, headache, fatigue, myalgia (muscle pain), arthralgia (joint pain) and rash will be reported in a standardized manner. They will be rated according to the FDA Guidance on Toxicity Grading Scales

    Measured: until Day 14, Day 28 and throughout the study period

  7. Assessment of viremia after each vaccination

    Assessment of CHIKV viremia will be done by RT (real-time)-qPCR (quantitative polymerase chain reaction) in blood and urine

    Measured: on Days 3, 7, 14 and beyond Day 14 after re-vaccination

  8. Immune response as measured by CHIKV-specific neutralizing antibody titer as determined by micro-neutralization (μNT) assay.

    Measured: Day 28, Day 84, Month 6, Month 12, and 28 days after re-vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VLA1553 in people with Chikungunya, run by Valneva Austria GmbH 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 7 inclusion and 21 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 29 Aug 2019. 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. 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?

Frequency of solicited injection site reactions (time frame: up to Day 14 after single vaccination). The study lists 4 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 NCT03382964, 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 29 Aug 2019.
