NCT03665454

Brief Summary

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.

Study Arms (2)

PF-06412562

EXPERIMENTAL

Subjects will receive 25 mg of PF-06412562 twice daily on study Days 2 and 3, along with placebo carbidopa/levodopa dosed at these times. Additional carbidopa/levodopa placebo capsules also will be administered according to the subject's home regimen.

Drug: PF-06412562

Standard of Care carbidopa/levodopa

ACTIVE COMPARATOR

Subjects will take placebo tablets for the PF-06412562 twice daily on study Days 2 and 3, along with active carbidopa/levodopa (25/100 mg) administered at these times. Additional active carbidopa/levodopa capsules also will be administered according to the subject's home regimen.

Drug: Standard of Care Placebo

Interventions

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.

PF-06412562

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

Also known as: Sinemet
Standard of Care carbidopa/levodopa

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of classic PD with history of clinically meaningful response to levodopa
  • Disease duration \>15 years since diagnosis
  • Hoehn \& Yahr stage \>IV "on" or "off" levodopa
  • Consent signed by subject, if possible
  • If subject is cognitively impaired, consent signed by power of attorney or legally authorized subject representative
  • Assent from the study subject, if possible

Masking Details
Investigational Drug Services, which is the investigational drug pharmacy at Hershey Medical Center, will be preparing and dispensing the drug. They will be the only party that is unblinded. Pfizer will provide placebo pills that are identical in appearance to the PF-06412562 study drug. The standard of care treatment, carbidopa/levodopa, is different in appearance to PF-06412562 and its corresponding matching placebo. In order to blind for this, Investigational Drug Services will encapsulate the carbidopa/levodopa pills. Thus, subjects may receive either an encapsulated carbidopa/levodopa pill or an empty non-active capsule, depending on the treatment arm and dosing they are scheduled to receive.

Intervention Model
CROSSOVER
Model Details: Subjects will participate in study for 2 consecutive weeks. Days 2-3 of Week 1, they will be blindly and randomly assigned to one of two treatment arms (study drug PF-06412562 or standard of care carbidopa/levodopa). Whichever treatment arm they did not receive during Week 1, they will receive during Days 2-3 of Week 2.
