What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) 1 Month After Vaccination
Time Frame: One month (28 to 42 days) after vaccination
Serotype-specific OPA GMTs for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) were determined in the blood samples of all the participants using a quantitative functional OPA assay. Confidence intervals (CIs) for GMT are back transformations of a CI based on the Student t distribution for the mean logarithm of the titers. Individual OPA assay values below the assay LLOQ (lower limit of quantification) were set at a titer of 0.5*limit of detection (LOD [8]) = (titer of 4) for the purpose of calculating the OPA GMT.
One month (28 to 42 days) after vaccination
Percentage of Participants Reporting Pre-Specified Local Reactions Within 14 Days After Vaccination
Time Frame: Within 14 days after vaccination
Local reactions reported using an electronic diary. Redness and Swelling scaled as Any (redness present or swelling present), Mild (2.5 to 5.0 centimeters [cm]), Moderate (5.1 to 10.0 cm), Severe (>10 cm). Pain at injection site scaled as Any (pain present), Mild (does not interfere with activity), Moderate (interferes with activity), Severe (prevents daily activity).
Within 14 days after vaccination
Percentage of Participants Reporting Pre-Specified Systemic Events Within 14 Days After Vaccination
Time Frame: Within 14 days after vaccination
Systemic events reported using electronic diary. Fever-Any:>=38 degrees Celsius (C), Mild (M):>=38 to <38.5 degrees C, Moderate(Mod):>=38.5 to <39 degrees C, Severe (S):>=39 to <=40 degrees C, Potentially life threatening:>40 degrees C. Headache, fatigue, muscle pain, joint pain- Any: present, M:did not interfere with activity, Mod:some interference, S:activity prevented. Vomiting- Any:present, M:1-2 times/day (d), Mod:>2/d, S:required intravenous hydration. Diarrhoea- Any:present, M:2-3 loose stools/d, Mod:4-5/d, S:>=6/d. All reports of fever >40 degrees C were confirmed as data entry errors.
Within 14 days after vaccination
Percentage of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)
Time Frame: Baseline up to 1 Month (28 to 42 days) after vaccination
An AE was any untoward medical occurrence in a participant who received vaccine without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial/prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between vaccination and up to 1 month (28 to 42 days) after vaccination that were absent before treatment or that worsened relative to pre-treatment state.
Baseline up to 1 Month (28 to 42 days) after vaccination

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving Serotype-Specific Opsonophagocytic Activity (OPA) Titer With at Least Lower Limit of Quantification (LLOQ) 1 Month After Vaccination
Time Frame: One month (28 to 42 days) after vaccination
Percentage of participants achieving OPA GMTs with at least LLOQ for 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) determined in blood samples of all participants using microcolony OPA assay. Exact 2-sided CI based on observed proportion of participants. LLOQ for each serotype: 1=1:18, 3=1:12, 4=1:21, 5=1:29, 6A=1:37, 6B=1:43, 7F=1:210, 9V=1:345, 14=1:35, 18C=1:31, 19A=1:18, 19F=1:48, 23F=1:13.
One month (28 to 42 days) after vaccination
Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Fold Rise (GMFR) From Pre-Vaccination to 1 Month Post-Vaccination
Time Frame: Pre-vaccination to 1 month (28 to 42 days) after vaccination
Geometric mean fold rises (GMFRs) for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from pre-vaccination to 1 month post-vaccination were computed using the logarithmically transformed assay results. CIs for GMFR are back transformations of a CI based on the Student t distribution for the mean logarithm of the titers.
Pre-vaccination to 1 month (28 to 42 days) after vaccination

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
