Brief Title  ICMJE PF 06412562 in Subjects With Advanced Stage Parkinson's Disease
Official Title  ICMJE 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
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.
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.
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: Randomized
Intervention Model: Crossover Assignment
Intervention Model Description:
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.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description:
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.
Primary Purpose: Treatment
Condition  ICMJE Parkinson Disease
Intervention  ICMJE
  • Drug: PF-06412562
    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.
  • Drug: Standard of Care Placebo
    25/100 mg tablet(s) of carbidopa/levodopa will be encapsulated and administered according to the subject's home regimen.
    Other Name: Sinemet
Study Arms  ICMJE
  • Experimental: PF-06412562
    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.
    Intervention: Drug: PF-06412562
  • Active Comparator: Standard of Care carbidopa/levodopa
    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.
    Intervention: Drug: Standard of Care Placebo
