AEs (all causalities), treatment related AEs and CTCAE severity grades for AEs were reported. Same participant may be reported in more than 1 CTCAE severity grade. Categories with at least 1 participant were reported.
Measured: Day 1 up to Day 64
Number of Participants With Positive Anti-drug Antibodies (ADA)
Human serum ADA samples of participants who received PF-04950615 (RN316) were analyzed for the presence of anti-PF-04950615 (RN316) antibodies. Results with titer value >=4.32 nanogram per milliliter of anti-PF-04950615 antibodies were counted as positive. Number of participants with presence of anti-PF-04950615 antibodies were reported in this outcome measure.
Measured: Day 1 up to Day 64

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing 4 mg/kg and 0.5 mg/kg in people with Hypercholesterolemia and Dyslipidemia, run by Pfizer at 5 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 2 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 1 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 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. 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 7 May 2015). 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?
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of PF-04950615 (time frame: 0 (pre-dose on Day 4), 1, 4, 8 and 12 hours (hrs) post intravenous PF-04950615 (RN316) dose, pre atorvastatin dose on Day 5, 6, 7, 15, 22, 29, 36, 43, 50, 57 and 64). The study lists 13 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 NCT01163851, which also lists 2 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 1 Mar 2018.
