A PHASE 2, OPEN LABEL EXTENSION STUDY TO INVESTIGATE THE LONG TERM SAFETY AND TOLERABILITY OF PF-06649751 IN SUBJECTS WITH MOTOR FLUCTUATIONS DUE TO PARKINSON'S DISEASE

Number of Participants With Treatment-Emergent Adverse Events (All Causalities)

时间窗: Baseline to last visit after termination (up to approximately 3 months)

An adverse event (AE) is any untoward medical occurrence in a study participant administered a product or medical device; the event need not necessarily have a causal relationship with the treatment or usage. Any AE occurring following the start of treatment or occurring before treatment but increasing in severity afterward were counted as treatment-emergent AE (TEAE).

Number of Participants With Vital Signs Data of Orthostatic Hypotension Meeting Pre-defined Criteria

时间窗: Baseline to last visit after termination (up to approximately 3 months)

Orthostatic hypotension was defined as a decrease of \>=20 mmHg for systolic blood pressure (SBP) or \>=10 mmHg for diastolic blood pressure (DBP) 2 minutes after standing from a supine position.

Number of Participants With Benzodiazepine Discontinuation Symptoms Based on Physician Withdrawal Checklist (PWC-20)

时间窗: At last visit

The PWC-20 is a physician-completed, 20-item reliable and sensitive instrument for the assessment of benzodiazepine discontinuation symptoms, including anxiety and nervous, depersonalization and derealization, diarrhea, diaphoresis, difficulty concentrating and remembering, dizziness-lightheadedness, depression, fatigue, lethargy and lack of energy, headaches, increased acuity for sound, smell, touch, or pain, insomnia, irritability, loss of appetite, muscle aches or stiffness, nausea-vomiting paresthesias, poor coordination, restlessness and agitation, tremor-tremulousness, and weakness. Summaries of the count of participants experiencing symptoms and severity listed in the PWC-20 were provided.

Number of Participants With Treatment-Emergent Adverse Events (Treatment Related)

时间窗: Baseline to last visit after termination (up to approximately 3 months)

An adverse event (AE) is any untoward medical occurrence in a study participant administered a product or medical device. Any AE occurring following the start of treatment or occurring before treatment but increasing in severity afterward were counted as treatment-emergent AE (TEAE).

Number of Participants With Clinically Significant Findings in Physical Examination

时间窗: Baseline to last visit after termination (up to approximately 3 months)

A full physical examination included head, ears, eyes, nose, mouth, skin, heart and lung examinations, lymph nodes, gastrointestinal and musculoskeletal systems. The clinical significance was determined by the investigator.

Number of Participants With Abnormalities in Laboratory Test (Without Regard to Baseline Abnormality)

时间窗: Baseline to last visit after termination(up to approximately 3 months)

Laboratory tests included hematology(hemoglobin,hematocrit,red and white blood cell count,mean corpuscular volume,mean corpuscular hemoglobin,mean corpuscular hemoglobin concentration,platelet count,neutrophils,eosinophils,monocytes, basophils,lymphocytes), chemistry(blood urea nitrogen/urea and creatinine,fasting glucose, calcium,sodium,potassium, chloride,total carbon dioxide,aspartate and alanine aminotransferase,total bilirubin,alkaline phosphatase,uric acid,albumin,total protein),urinalysis(pH,qualitative glucose protein,blood,ketones,nitrites,leukocyte esterase,urobilinogen,urine bilirubin,microscopy,specific gravity,urine creatinine),other tests(urine drug screen,follicle stimulating hormone,anti neutrophil cytoplasmic antibody panel,qualitative antinuclear antibody,fibrinogen,C reactive protein,erythrocyte sedimentation rate,C3, C4, CH50/CH100,rheumatoid factor,immunoglobulin panel,if anti- neutrophil cytoplasmic antibody positive:proteinase 3 Ab,myeloperoxidase Ab tests).

Number of Participants With Clinically Significant Findings in Neurological Examination

时间窗: Baseline to last visit after termination (up to approximately 3 months)

The full neurological examination included assessment of the visual fields and of the right and left optic fundus; cranial nerves; mental state; muscle strength and tone, abnormal movements; deep tendon reflexes; sensory exam, coordination, gait and station. Higher cortical and motor function was considered part of the complete neurological exam. The brief neurological exam included observation for cerebellar (intention) tremor and for non cerebellar tremors (eg, resting or positional), finger to nose, heel to shin, Romberg, gait and tandem walking, positional and gaze evoked nystagmus. The clinical significance was determined by the investigator.

Number of Participants With Vital Signs Data Meeting Pre-defined Criteria

时间窗: Baseline to last visit after termination (up to approximately 3 months)

Number of participants with vital signs findings meeting the following criteria is presented:(1) standing DBP increase from baseline\>= 20 mm Hg; (2) standing SBP increase from baseline\>= 30 mm Hg; (3) supine DBP increase from baseline \>=20 mm Hg; (4) supine SBP increase from baseline \>=30 mm Hg; (5)standing DBP decrease from baseline\>= 20 mm Hg; (6) standing SBP decrease from baseline\>= 30 mm Hg; (7) supine DBP decrease from baseline \>=20 mm Hg; (8) supine SBP decrease from baseline \>=30 mm Hg.

Number of Participants With Electrocardiogram Data Meeting Pre-defined Criteria

时间窗: Baseline to last visit after termination (up to approximately 3 months)

PR interval (time from the beginning of P wave to the start of QRS complex, corresponding to the end of atrial depolarization and onset of ventricular depolarization), QRS duration (time from Q wave to the end of S wave, corresponding to ventricle depolarization), QT interval (time from the beginning of Q wave to the end of T wave) and QTcF interval ( QT interval corresponding to electrical systole corrected for heart rate using Fridericia's formula) are summarized. Number of participants with ECG findings meeting the following criteria is presented: (1) PR interval \>=300 msec; (2) QRS duration \>=140 msec; (3) QT interval \>= 500; (4) QTcF interval: 450 to \<480 msec; (5) QTcF interval: 480 to \<500 msec; (6) QTcF interval \>=500 msec.

Number of Participants With Worsening Suicidality and New Onset Suicidality

时间窗: Baseline to last visit after termination (up to approximately 3 months)

The Columbia Suicide Severity Rating Scale (C-SSRS) is an interview based rating scale to systematically assess suicidal ideation and suicidal behavior. At each suicidality assessment, participants felt to have significant suicidal ideation with actual plan and intent or suicidal behavior, must be evaluated by a clinician/mental health professional (MHP) skilled in the evaluation of suicidality in the participants by virtue of training or experience who determined if it is safe for the participants to participate/continue in the trial. The denominator used in the percentages was the number of participants assessed for suicidality or worsening, the denominator included the subset of participants who had any level of suicidality reported at baseline. For new onset, the denominator included the subset of participants with no suicidality reported at baseline.
