What is being measured

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

  1. Percentage of participants with treatment emergent adverse events (TEAEs) including serious AEs (SAEs), medically attended adverse events (MAAEs), potentially immune mediated medical conditions (PIMMCs) and new onset chronic diseases (NOCDs)

    An adverse event (AE) is any untoward medical occurrence in a subject administered an investigational product (IP), and which does not necessarily have to have a causal relationship with this treatment. TEAE is defined as an AE occurring after study immunization to the last visit (up to 30 days post-vaccination if the study is discontinued for an individual subject). An IP-related TEAE is defined as any TEAE with a causal relationship assessed as "yes" by the investigator or subinvestigator.

    Measured: Up to Day 30

  2. Percentage of participants with vital sign abnormalities and/or adverse events (AEs)

    Percentage of participants with potentially clinically significant vital sign values.

    Measured: Up to Day 30

  3. Percentage of participants reporting solicited local adverse reactions

    Local reactions include pain, tenderness, erythema/redness, swelling, and induration. The reaction will be graded with 4-range grade: 1 (mild) to 4 (potentially life-threatening).

    Measured: Up to Day 7

  4. Percentage of participants reporting solicited systemic adverse reactions

    Systemic reactions include nausea, vomiting, diarrhea, headache, fever, fatigue and myalgia and arthralgia. Vital signs up to 7 days postvaccination are collected as systemic reactions. The reaction will be graded with 4-range grade: 1 (mild) to 4 (potentially life-threatening).

    Measured: Up to Day 7

  5. Percentage of participants with laboratory value abnormalities and/or adverse events (AEs)

    Percentage of participants with potentially clinically significant laboratory values.

    Measured: Up to Day 30

  6. Percentage of participants with electrocardiogram (ECG) abnormalities and/or Adverse Events (AEs)

    Percentage of participants with potentially clinically significant ECG values.

    Measured: Up to Day 30

  7. Percentage of participants with physical exam abnormalities and/or adverse events (AEs)

    Percentage of participants with potentially clinically significant physical exam values.

    Measured: Up to Day 30

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ASP3772 (subcutaneous), ASP3772 (intramuscular) and PPSV23 (subcutaneous) in people with Healthy Volunteers, run by Affinivax, Inc. at 1 site in Japan.

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 5 inclusion and 8 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 2 May 2022. 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 Japan. 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?

Percentage of participants with treatment emergent adverse events (TEAEs) including serious AEs (SAEs), medically attended adverse events (MAAEs), potentially immune mediated medical conditions (PIMMCs) and new onset chronic diseases (NOCDs) (time frame: Up to Day 30). The study lists 7 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 NCT04265911, 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 2 May 2022.
