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

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Cohort 2: Baseline Absolute Lymphocyte Count in Cerebrospinal Fluid (CSF)
Time Frame: Baseline
The primary CSF endpoint of Cohort 2 was the percent change from baseline in absolute lymphocyte counts in CSF after 3 doses of PF-00547659. The hypothesis for the primary endpoint was evaluated using the CSF evaluable population in Cohort 2. CSF samples were obtained via lumbar puncture and analyzed by fluorescence-activated cell sorting (FACS) for total lymphocyte counts. Lumbar punctures were performed by a highly qualified physician using a 20-22 gauge needle, preferably an atraumatic needle.
Baseline
Cohort 2: Percent Change From Baseline in Absolute Lymphocyte Count in CSF at Month 3
Time Frame: Baseline, Month 3
The primary CSF endpoint of Cohort 2 was the percent change from baseline in absolute lymphocyte counts in CSF after 3 doses of PF-00547659. The hypothesis for the primary endpoint was evaluated using the CSF evaluable population in Cohort 2. CSF samples were obtained via lumbar puncture and analyzed by FACS for total lymphocyte counts. Lumbar punctures were performed by a highly qualified physician using a 20-22 gauge needle, preferably an atraumatic needle.
Baseline, Month 3

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
Cohorts 1 and 2: Total Number of Participants With Non-Lumbar Puncture (LP) Related Treatment-Emergent Adverse Events (AEs), Withdrawals Due to AEs, and Serious Adverse Events (SAEs) During the 12-week Treatment Period
Time Frame: Baseline up to Week 12
An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly/birth defect. Treatment-emergent for this measure are events between first dose of study drug and up to 85 days (Week 12) after last dose that were absent before treatment or that worsened relative to pretreatment state. AEs included serious and non-serious AEs.
Baseline up to Week 12
Cohorts 1 and 2: Number of Participants Who Developed Anti-Drug Antibodies (ADAs) to PF-00547659
Time Frame: Day 1; Weeks 4, 8, 9-11 (Cohort 2 only), 12, 20, 28, and 36; Early Withdrawal
Serum samples were analysed for presence of ADAs to PF-00547659. Participants who showed positive results for PF-00547659 were reported.
Day 1; Weeks 4, 8, 9-11 (Cohort 2 only), 12, 20, 28, and 36; Early Withdrawal
Cohorts 1 and 2: Number of Participants With Injection Site Reactions by Severity
Time Frame: Baseline till End of Study/Early Withdrawal, up to Week 12
Injection site reaction AEs include: injection site irritation, injection site pain, injection site rash, contusion, and erythema.
Baseline till End of Study/Early Withdrawal, up to Week 12

Primary Completion (Actual)

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. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
