What is being measured

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

  1. Percentage of Participants Reporting Pre-Specified Local Reactions Within 7 Days After Vaccination in Participants Aged Between 6 to <18 Years

    Local reactions were recorded using an electronic daily diary. Local reactions included redness, swelling and pain at injection site. Redness and swelling were graded as mild (0.5 to 2.0 centimeter [cm]), moderate (greater than [>] 2.0 to 7.0 cm) and severe (>7.0 cm) for participants aged 6 to <12 years, and as mild (2.5 to 5.0 cm), moderate (>5.0 to 10.0 cm) and, severe (>10.0 cm) for participants aged 12 to <18 years. Pain at injection site was graded as mild (did not interfere with activity), moderate (interfered with activity), and severe (prevented daily activity).

    Measured: Day 1 up to Day 7

  2. Percentage of Participants Reporting Pre-Specified Local Reactions Within 14 Days After Vaccination in Participants Aged Between 18 to <65 Years

    Local reactions were recorded using an electronic daily diary. Local reactions included redness, swelling and pain at injection site. Redness and swelling were graded as mild (2.5 to 5.0 cm), moderate (>5.0 to 10.0 cm) and, severe (>10.0 cm). Pain at injection site was graded as mild (did not interfere with activity), moderate (interfered with activity), and severe (prevented daily activity).

    Measured: Day 1 up to Day 14

  3. Percentage of Participants Reporting Systemic Events and Use of Antipyretic or Pain Medication Within 7 Days After Vaccination in Participants Aged Between 6 to <18 Years

    Systemic events included fever, vomiting, diarrhea, headache, fatigue, muscle and joint pain, and were recorded by using an e-diary. Use of antipyretic or pain medication was also collected by using an e-diary. Fever was graded as 37.5 to 38.4 degree Celsius (C), 38.5 to 38.9 degree C, 39.0 to 40.0 degree C and >40.0 degree C. Vomiting was graded as mild (1-2 times in 24 hours), moderate (>2 times in 24 hours) and severe (required intravenous hydration). Diarrhea was graded as mild (2-3 loose stools in 24 hours), moderate (4-5 loose stools in 24 hours) and severe (greater than or equals to [>=] 6 loose stools in 24 hours). Headache, fatigue, muscle pain and joint pain were graded as mild (no interference with activity), moderate (some interference with activity) and severe (significant, prevented daily activity).

    Measured: Day 1 up to Day 7

  4. Percentage of Participants Reporting Systemic Events and Use of Antipyretic or Pain Medication Within 14 Days After Vaccination in Participants Aged Between 18 to <65 Years

    Systemic events included fever, vomiting, diarrhea, headache, fatigue, muscle and joint pain, and were recorded by using an e-diary. Use of antipyretic or pain medication was also collected by using an e-diary. Fever was graded as 37.5 to 38.4 degree C, 38.5 to 38.9 degree C, 39.0 to 40.0 degree C and >40.0 degree C. Vomiting was graded as mild (1-2 times in 24 hours), moderate (>2 times in 24 hours) and severe (required intravenous hydration). Diarrhea was graded as mild (2-3 loose stools in 24 hours), moderate (4-5 loose stools in 24 hours) and severe (>=6 loose stools in 24 hours). Headache, fatigue, muscle pain and joint pain were graded as mild (no interference with activity), moderate (some interference with activity) and severe (significant, prevented daily activity).

    Measured: Day 1 up to Day 14

  5. Percentage of Participants Reporting Adverse Events (AEs) and Serious Adverse Events (SAEs)

    An AE was any untoward medical occurrence in a participant who received study vaccine without regard to possibility of causal relationship. An SAE is any untoward medical occurrence at any dose that results in death; is life-threatening (immediate risk of death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); results in congenital anomaly/birth defect.

    Measured: signing of informed consent form (Day 1) up to Day 43

Secondary outcomes (4)
  1. Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) at Pre-vaccination and 1 Month After Vaccination

    Antibody-mediated serum OPA against each of the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) was measured centrally using a quantitative functional microcolony OPA (mcOPA) assay. Results were expressed as OPA titers. OPA titers were logarithmically transformed for analysis; geometric means calculated and expressed as geometric mean titers (GMTs). Two (2)-sided 95% CIs were constructed by back transformation of the CI for the mean of the logarithmically transformed assay results computed based on the Student t distribution. OPA titer was expressed as reciprocal of highest serum dilution.

    Measured: Pre-vaccination and 1 month after vaccination

  2. Geometric Mean Fold Rises (GMFRs) in Serotype-specific OPA Titers 1 Month After Vaccination

    OPA GMFRs were calculated along with corresponding 2-sided 95% CIs for pneumococcal serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F. GMFRs were computed as the fold rise in titer value at 1 month after vaccination compared to baseline (pre-vaccination). The CIs for GMFRs were back transformations of a CI based on the Student t distribution for the mean difference of the log-transformed assay results before vaccination and 1 month after vaccination.

    Measured: Pre-vaccination to 1 month after vaccination

  3. Serotype-specific Immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) at Pre-vaccination and 1 Month After Vaccination

    Pneumococcal IgG antibody against each of the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) was measured centrally using direct binding Luminex assay. Results were expressed as IgG concentrations. IgG concentrations were logarithmically transformed for analysis; geometric means calculated and expressed as GMCs. Two (2)-sided 95% CIs were constructed by back transformation of the CI for the mean of the logarithmically transformed assay results computed based on the Student t distribution.

    Measured: Pre-vaccination and 1 month after vaccination

  4. GMFRs in Serotype-specific IgG From Before Vaccination to 1 Month After Vaccination

    IgG GMFRs were calculated along with corresponding 2-sided 95% CIs for pneumococcal serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F. GMFRs were computed as the fold rise in concentrations at 1 month after vaccination compared to baseline (pre-vaccination). The CIs for GMFRs were back transformations of a CI based on the Student t distribution for the mean difference of the log-transformed assay results before vaccination and 1 month after vaccination.

    Measured: Pre- vaccination to 1 month after vaccination

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 10 Dec 2019). 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?

Percentage of Participants Reporting Pre-Specified Local Reactions Within 7 Days After Vaccination in Participants Aged Between 6 to <18 Years (time frame: Day 1 up to Day 7). The study lists 5 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 NCT03571607, 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 18 Feb 2020.
