About this study

Official title: A Phase Ib Safety, Tolerability, and Efficacy Study of Two Days of Oral Split Dose (25/20 mg) Administration of PF 06412562 in Subjects With Advanced Stage Parkinson's Disease

The purpose of this study is to test the safety and tolerability of the investigational drug PF-06412562 compared to the current medical standard of care medication for Parkinson's disease, carbidopa/levodopa. This research also is being done to find out if the investigational drug PF-06412562 can help improve the motor (movement) function, alertness, and cognitive (thinking) skills of people who are considered to be in the advanced-stage of Parkinson's disease. In this study, PF06412562 is 'investigational,' which means that it is experimental and has not been approved by the US Food and Drug Administration (FDA), but can be used in clinical research studies such as this one.

Read the detailed description

The investigators are conducting a randomized, double-blind, carbidopa/levodopa-controlled crossover safety, tolerability, and efficacy study of the investigational compound, PF-06412562, in advanced Parkinson's patients. The primary purpose of this study is to test the safety and tolerability of the investigational drug PF-06412562 compared to the current medical standard of care medication for Parkinson's disease, carbidopa/levodopa, in these patients. This secondary purpose of this research is to find out if the investigational drug PF-06412562 can help improve the motor (movement) function, alertness, and cognitive (thinking) skills of people who are considered to be in the advanced-stage of Parkinson's disease. This study will inform the field as to whether PF-06412562 is safe and well-tolerated in advanced Parkinson's patients, and also may provide preliminary data on its efficacy in several domains.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PF-06412562Drug

    PF-06412562 is a dopamine agonist developed by Pfizer Inc. into a tablet form for oral usage. It will be provided as 5 mg tablets. Thus, to administer the 25 mg dose, 5 x 5 mg tablets will be given; and to administer the 20 mg dose, 4 x 5 mg tablets will be administered.

  • Standard of Care PlaceboDrug

    Also called Sinemet

    25/100 mg tablet(s) of carbidopa/levodopa will be encapsulated and administered according to the subject's home regimen.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06412562 in people with Parkinson Disease, run by Milton S. Hershey Medical Center 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 7 inclusion and 4 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 31 Jul 2019. 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. 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?

Safety and tolerability of PF-06412562 assessed by blood sample results (time frame: Day 1). The study lists 46 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 NCT03665454, 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 31 Jul 2019.
