Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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
Percentage of Participants With an Adverse Event (AE)
Time Frame: Up to 14 days after vaccination
The percentage of participants experiencing ≥1 AE(s) in each arm was determined. An AE is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
Up to 14 days after vaccination
Percentage of Participants With a Solicited Injection-site Adverse Event (AE)
Time Frame: Up to 14 days after vaccination
The percentage of participants experiencing ≥1 solicited injection-site AE(s) in each arm was determined.
Up to 14 days after vaccination
Percentage of Participants With a Solicited Systemic Adverse Event (AE)
Time Frame: Up to 14 days after vaccination
The percentage of participants experiencing ≥1 solicited systemic AE(s) in each arm was determined.
Up to 14 days after vaccination
Percentage of Participants With a Serious Adverse Event (SAE)
Time Frame: Up to 30 days after vaccination
The percentage of participants experiencing ≥1 SAE(s) in each arm was determined.
Up to 30 days after vaccination
Percentage of Participants With Vaccine-Related Serious Adverse Event (SAE)
Time Frame: Up to 30 days after vaccination
The percentage of participants experiencing ≥1 vaccine-related SAEs(s) in each arm was determined.
Up to 30 days after vaccination
Geometric Mean Titers (GMTs) of Serotype-specific Opsonophagocytic Killing Activity (OPA) at One Month Post-Vaccination
Time Frame: Day 30 (one month after vaccination)
The OPA GMTs of each common serotype (CS) and V114-specific serotype (VS) were determined in each arm. Titer levels were determined with the multiplexed opsonophagocytic assay (MOPA).
Day 30 (one month 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
Geometric Mean Concentrations (GMCs) of Serotype-specific Immunoglobulin G (IgG) at One Month Post-Vaccination
Time Frame: Day 30 (one month after vaccination)
The IgG GMCs of each common pneumococcal serotype (CS) and V114-specific pneumococcal serotype (VS) were determined for each arm. Concentrations were determined with pneumococcal electrochemiluminescence (PnECL).
Day 30 (one month after vaccination)
Percentage of Participants With a ≥4-fold Rise From Baseline in Serotype-specific Opsonophagocytic Killing Activity (OPA) Geometric Mean Titers (GMTs)
Time Frame: Baseline and Day 30 (one month after vaccination)
The percentage of participants with ≥4-fold rise from baseline in OPA GMTs of each common serotype (CS) and V114-specific serotype (VS) were compared in the V114 and Prevnar® 13 arms. Estimated GMT, GMT ratio, 95% CI, and p-values were obtained from a constrained longitudinal data analysis (cLDA) model.
Baseline and Day 30 (one month after vaccination)
Percentage of Participants With a ≥4-fold Rise From Baseline in Geometric Mean Concentrations (GMCs) of Serotype-specific Immunoglobulin G (IgG) Antibodies
Time Frame: Baseline and Day 30 (one month after vaccination)
The percentage of participants with ≥4-fold rise from baseline in IgG GMCs of each common serotype (CS) and V114-specific serotype (VS) were compared in the V114 and Prevnar® 13 arms. Estimated GMT, GMT ratio, 95% CI, and p-values were obtained from a constrained longitudinal data analysis (cLDA) model.
Baseline and Day 30 (one month after vaccination)
