What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Dose Limiting and Intolerable Treatment-Related Adverse Events (AEs)
An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Dose limiting and intolerable treatment-related AEs were the AEs resulting from drug overdose, drug withdrawal, drug abuse, drug misuse, drug interactions, drug dependency, extravasation, exposure in utero, exposure during breast feeding.
Measured: Baseline up to Follow-up period (Day 78)
Number of Participants With Treatment-Emergent Adverse Events (AEs), Serious Adverse Events (SAEs) and Treatment-Related Adverse Events (AEs)
An AE was any untoward medical occurrence in participant who received study drug 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 or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug.

Secondary outcomes (41)
Area Under the Curve From Time Zero to End of Dosing Interval (AUCtau) of PF-04950615
AUCtau is area under the concentration-time profile from time zero to time tau (τ), the dosing interval, where tau =168 hours.
Measured: Day 1 and 22: pre-dose and 1, 6, 9, 24 and 72 hours post dose
Time to Reach Maximum Observed Plasma Concentration (Tmax) of PF-04950615

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PF-04950615 (RN316) in people with Hypercholesterolemia and Dyslipidemia, run by Pfizer at 9 sites 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 3 inclusion and 3 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 22 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites 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?
Yes. Results are posted in the registry (first posted 22 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Participants With Dose Limiting and Intolerable Treatment-Related Adverse Events (AEs) (time frame: Baseline up to Follow-up period (Day 78)). The study lists 7 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 NCT01243151, which also lists 3 linked publications.
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 22 Jan 2019.
