A Phase 1 study testing PF-06650833 in people with Healthy, run by Pfizer at 1 site in United States.
Trial summary
This single ascending dose study is the first evaluation of PF-06650833 in humans. The goals are to assess the safety, tolerability and blood levels of ascending doses of multiple formulations of PF-06650833 and to perform a preliminary assessment of the effect of food on exposure, in healthy subjects.

Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 55 years
- All sexes
- Healthy volunteers accepted
- Adult
Who may be able to join
- Healthy male and/or female subjects of non childbearing potential between the ages of 18 and 55 years, inclusive.
- Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lbs).
Who cannot join
- Screening supine blood pressure 100 mm Hg (systolic) or 50 mm Hg (diastolic); or 140 mm Hg (systolic) or 90 mm Hg (diastolic) following at least 5 minutes of supine rest. If blood pressure (BP) is 140 mm Hg (systolic) or 90 mm Hg (diastolic), the BP should be repeated two more times and the average of the three BP values should be used to determine the subject's eligibility.

Key inclusion criteria (2 listed)
- Healthy male and/or female subjects of non childbearing potential between the ages of 18 and 55 years, inclusive.
- Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lbs).
Key exclusion criteria (2 listed)
- Screening supine blood pressure 100 mm Hg (systolic) or 50 mm Hg (diastolic); or 140 mm Hg (systolic) or 90 mm Hg (diastolic) following at least 5 minutes of supine rest. If blood pressure (BP) is 140 mm Hg (systolic) or 90 mm Hg (diastolic), the BP should be repeated two more times and the average of the three BP values should be used to determine the subject's eligibility.
- Pulse or heart rate (HR) >100 bpm after at least 5 minutes of rest. If the pulse/HR is >100 bpm, the pulse/HR should be repeated two more times (separated by at least 2 minutes) and the average of the three pulse/HR values should be used to determine the subject's eligibility.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PF-06650833 in people with Healthy, run by Pfizer at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Incidence and severity of treatment emergent adverse events and withdrawals due to treatment emergent adverse events (time frame: Baseline-5 days). The study lists 4 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 NCT02224651, 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 2 Jul 2015.
