Phase

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.

Ages Eligible for Study

65 years and older (Older Adult)

Accepts Healthy Volunteers

Yes

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
Geometric Mean Titer 21 Days After the Study Vaccination
Time Frame: 21 days after vaccination
21 days after vaccination
Percentage of Participants With Seroconversion 21 Days After the Study Vaccination
Time Frame: 21 days after vaccination
Seroconversion rate was defined as the proportion of participants with a HI titer of less than 1:10 before vaccination achieving a HI antibody titer of 1:40 or more after vaccination, or with a HI titer of 1:10 or more before vaccination achieving a four-fold or greater increase in HI titer after vaccination.
21 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
Frequency and Intensity of Local and Systemic Solicited Symptoms
Time Frame: 5 days after vaccination
5 days after vaccination
Duration of Local and Systemic Solicited Symptoms
Time Frame: 5 days after vaccination
5 days after vaccination
Frequency and Intensity of Unsolicited Adverse Events (UAEs)
Time Frame: 21 days after vaccination
Abbreviation UAE stands for Unsolicited Adverse Event.
21 days after vaccination
Serious Adverse Events
Time Frame: 180 days after vaccination
180 days after vaccination
New Onsets of Chronic Illness
Time Frame: 180 days after vaccination
A NOCI was defined as the diagnosis of a chronic medical condition where the symptoms commenced or worsened following exposure to the study vaccine and may have included those potentially controllable by medication (e.g., glaucoma, hypertension).
