What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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)

  2. 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. Treatment-emergent are events between first dose of study drug and up to Day 78 that were absent before treatment or that worsened relative to pretreatment state.

    Measured: Baseline up to Follow-up period (Day 78)

  3. Number of Participants With Adverse Events (AEs) by Severity

    An AE was any untoward medical occurrence in a participant who received study drug. AE was assessed according to common terminology criteria for adverse events (CTCAE) version 4.0 severity grades- Grade 1: mild (asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated); Grade 2: moderate (minimal, local or non invasive intervention indicated); Grade 3: severe (medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling); Grade 4: Life-threatening consequences; urgent intervention indicated and Grade 5: Death related to AE.

    Measured: Baseline up to Follow-up period (Day 78)

  5. Number of Participants With Clinically Relevant Changes in Vital Signs

    Criteria for clinically relevant vital signs: supine and standing systolic blood pressure (SBP): less than (<) 90 millimeter of mercury (mmHg); supine and standing diastolic blood pressure (DBP): <50 mmHg. Maximum increase from baseline (IFB) or decrease from baseline (DFB) in supine and standing SBP: greater than or equal to (>=) 30 mmHg and maximum IFB or DFB in supine and standing DBP: >=20 mmHg.

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.
