Overview

This is a First in human (FIH) single ascending dose study to evaluate the safety, tolerability and pharmacokinetics (PKs) of BIIB118 following single oral doses in healthy human subjects

This study was previously posted by Pfizer. In March, 2020, sponsorship of the trial was transferred to Biogen.

Medical Language ↔ Plain English

Inclusion Criteria: •Healthy male and/or female subjects of non-childbearing potential between the ages of 18 and 55 years, inclusive (Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12-lead ECG and clinical laboratory tests). Female subjects of non-childbearing potential must meet at least one of the following criteria: 1. Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; and have a serum follicle-stimulating hormone (FSH) level confirming the post-menopausal state; 2. Have undergone a documented hysterectomy and/or bilateral oophorectomy; 3. Have medically confirmed ovarian failure. All other female subjects (including females with tubal ligations and females that do NOT have a documented hysterectomy, bilateral oophorectomy and/or ovarian failure) will be considered to be of childbearing potential. * Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight \>50 kg (110 lbs). * Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study. * Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures. Exclusion Criteria: * Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing). * Treatment with an investigational drug within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of study medication (whichever is longer). * Screening supine blood pressure \>= 140 mm Hg (systolic) or \>=90 mm Hg (diastolic), following at least 5 minutes of rest. If BP is \>=140 mm Hg (systolic) or \>=90 mm Hg (diastolic), repeat per local standard operating procedures (SOP). If orthostatic changes are present and deemed to be clinically significant by the investigator, Subject can be excluded.

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. A serious adverse event (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.

Change From Baseline in Bond and Lader Visual Analogue Scale (BL-VAS) at 2 Hours Post Dose in Cohorts 1 and 2

The BL-VAS monitored the subjective mood of each participant on 16 mood scales. Participants were asked to indicate on the VAS scale ranging from 0 to 100 mm about how they felt at the moment the scale was administered (example, alert/drowsy; calm/excited; content/tensed). The individual responses from the 16 mood scales were then combined to make three affective dimensions/subscales a) alertness (average of 9 items \[total range 0 to 100, where each item is ordered so that higher scores indicated more alertness\]), b) contentment (average of 2 items \[total range 0 to 100, where higher scores indicated more contentment\]), and c) calmness (average of 5 items \[total range 0 to 100, where higher scores indicated more calmness\]). Baseline is defined as the last available recording prior to dosing on Day 1 of the first Period.

Change From Baseline in Extrapyramidal Symptom Rating Scale (ESRS) at 2 Hours Post Dose in Cohorts 1 and 2

ESRS is a clinician rated scale to assess parkinsonism,dystonia,dyskinesia,akathisia.The ESRS consists of 4 subscales and 4 clinicians global impressions-severity scales(CGI-S scales):I)a questionnaire of extrapyramidal symptoms or drug-induced movement disorders(a series of 4-point Likert scale questions with 0=Absent and 3=Severe);II)an examination of Parkinsonism and akathisia(7-point Likert scale with 0=Absent,6=extremely severe);III)an examination of dystonia(7-point Likert scale with 0=Absent,6=extremely severe);IV)an examination of dyskinesia(7-point Likert scale with 0=normal,6=most severe);V)toVIII)CGI-S scales(9-point Likert scale with 0=Absent,8=extremely severe)of tardive dyskinesia,parkinsonism,dystonia,akathisia.ESRS-Parkinsonism:total score range:0 to 14 where higher scores indicates greater severity;ESRS-dystonia:total score range:0 to 14 where higher scores indicates greater severity.Change from baseline was only observed in examination of parkinsonism and dystonia.
