简要总结

The purpose of this study is to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple doses of BN201 in healthy subjects.

This is a phase I, randomised, double-blind, placebo-controlled study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of BN201 in healthy subjects following single ascending doses and two cohorts of multiple doses. The study will be conducted in two parts (Part A and Part B). Part A (up to 8 single ascending doses (SD)) will be conducted in 32 subjects (4 interlocking cohorts of 8 subjects). Part B (up to 2 multiple ascending doses (MD)) will be conducted in 16 subjects (2 cohorts of 8 subjects). Subjects in Part A will undergo a screening period (Day -28 to Day -2), two in-patient treatment periods compromising 3 overnight stays (from Day -1 to Day 3) with a wash out period of at least 14 days between dose administrations and a follow up visit 12 to 16 days following administration of IMP. Subjects in Part B will undergo a screening period (Day -28 to Day -2), an in-patient treatment period compromising 7 overnight stays (from Day -1 to Day 7) and a follow up visit 12 to 16 days following final administration of Investigational Medicinal Product (IMP).

详细描述

Screening (Days -28 to -2) Screening assessments will be performed within 28 days of the first dose to ensure the eligibility of participants. Assessments will include medical history, demographics, concomitant medication check, physical examination, body weight, height, BMI, HIV, Hepatitis B and Hepatitis C screen, drugs of abuse and alcohol screen, routine laboratory assessments (biochemistry, haematology and urinalysis), 12-lead ECG, EEG monitoring, brain MRI scan, vital signs (supine systolic and diastolic blood pressure, pulse) and body temperature. Female participants will also be screened for pregnancy and hormone status. A C-SSRS questionnaire will also be performed at screening for Part B only.

Treatment Period

Part A:

Up to four cohorts ((SD1), (SD2), (SD3), (SD4)) of eight subjects will be randomly assigned to receive either two single intravenous doses of BN201, two single intravenous doses of placebo or one single intravenous dose of BN201 and placebo (per treatment period) over two treatment periods (Period 1 and Period 2). Within each cohort, 6 subjects will receive BN201 and 2 subjects will receive placebo. Two "dose leader" subjects will be dosed on the same day, at least 48 h before the remaining subjects in the cohort. Of these two subjects, one will be dosed with BN201 and the other with placebo. The Chief Investigator (or delegate) must confirm it is safe to continue with the dosing of the remainder of the cohort following review of appropriate safety data. The remaining 6 subjects of the cohort (five randomised to active and one to placebo) will then be dosed.

Subjects will be admitted to the clinical unit in the morning of Day -1 and will remain in the unit until the 48 h post dose scheduled assessments and procedures have been performed (Day 3). On Day -1 of each Treatment Period subjects' eligibility will be re-assessed and blood and urine samples will be collected for laboratory safety tests (including drugs of abuse and alcohol screen, biochemistry, haematology, urinalysis and serum pregnancy test). A 12-lead ECG, vital signs (supine systolic and diastolic blood pressure, pulse), body temperature, adverse event and concomitant medication checks will be performed. The intravenous dose of BN201 or placebo will be based on body weight measured on Day -1. An evening snack will be consumed at least 10 hours (h) before (each) dose administration.

入选标准

•To be confirmed at screening:
•Healthy male and female subjects between 18 and 55 years of age.
•*Healthy subjects as determined by past medical history and as judged by the PI (including no significant infection in the last 3 months before trial enrolment).
•*Female subject of non-child bearing potential with negative pregnancy test at screening and each admission to the clinical unit. For the purposes of this study, this is defined as the subject being amenorrheic for at least 12 consecutive months or at least 4 months post-surgical sterilisation (including bilateral fallopian tube ligation or bilateral oophorectomy with or without hysterectomy). Menopausal status will be confirmed by demonstrating at screening that levels of follicle stimulating hormone (FSH) fall within the respective pathology reference range. In the event a subject's menopause status has been clearly established (for example, the subject indicates she has been amenorrheic for 10 years), but FSH levels are not consistent with a post-menopausal condition, determination of subject eligibility will be at Investigator's discretion following consultation with the Sponsor.
•*Female subjects of child bearing potential must be non-pregnant and non-lactating with negative pregnancy test at screening and each admission to the clinical unit.
•*Female subjects of child bearing potential and male subjects with female partners of child bearing potential must take one highly effective contraceptive precaution in addition to one acceptable contraceptive precaution (i.e., barrier precaution) from first dose until 3 months after last dose of IMP (as detailed in Section 9.4.1).
•*Male subject willing to use an effective method of contraception or 2 effective methods of contraception, i.e., highly effective method of contraception + condom, if applicable (unless anatomically sterile or where abstaining from sexual intercourse is in line with the preferred and usual lifestyle of the subject) from first dose until 3 months after last dose of IMP.
•*Subject with a body weight of ≥ 50.0 kg and ≤100 kg and have a body mass index (BMI) of 18-32 kg/m
•BMI = body weight (kg) / [height (m)]
•*Subject with no clinically significant history of previous allergy / sensitivity to BN201 or any of the excipients contained within the IMP.
•*Subject with no clinically significant abnormal serum biochemistry, haematology and urine examination values within 28 days before the first dose of IMP.
•*Subject with a negative urinary drugs of abuse screen, determined within 28 days before the first dose of IMP (N.B. a positive alcohol result may be repeated at Investigator's discretion).
•Subject with negative human immunodeficiency virus (HIV) and hepatitis B surface antigen (HBsAg) and hepatitis C virus antibody (HCV) results.
•*Subject with no clinically significant abnormalities in 12-lead electrocardiogram ((QTcF ≤ 430 ms) and (PR 120 - 200 ms)) determined within 28 days before first dose of IMP.
•Subjects with no clinically significant abnormalities in electroencephalogram (EEG) determined within 28 days before first dose of IMP.
•*Subject with no clinically significant abnormalities in vital signs (supine systolic and diastolic blood pressure, pulse) and body temperature determined within 28 days before first dose of IMP.
•Subject must be available to complete the study (including all follow up visits).
•Subject must satisfy the investigator / designee about their fitness to participate in the study.
•Subject must be willing and able to sign the written informed consent to participate in the study.
•Subjects must not donate sperm for the first dose and for at least 3 months after the last dose of IMP.
•Subject with no clinically significant abnormalities in brain MRI scan determined within 28 days before first dose of IMP.
•To be re-confirmed on Day -1 / prior to dosing:
•Subject continues to meet all screening inclusion criteria indicated with * (BMI will only apply to screening).
•Subject with a negative urinary drugs of abuse screen (including alcohol) prior to dosing.
•Female subject with negative pregnancy test.

•Evidence of renal, hepatic, central nervous system, respiratory, cardiovascular or metabolic dysfunction.
•A clinically significant history of drug or alcohol abuse.
•Users of nicotine products i.e., current smokers or ex-smokers who have smoked within the 6 months prior to dosing with the study medication or users of cigarette replacements (i.e., e-cigarettes, nicotine patches or gums).
•Inability to communicate well with Investigators (i.e., language problem, poor mental development or impaired cerebral function).
•Participation in a New Chemical Entity clinical study within the previous 3 months or a marketed drug clinical study within the 30 days before the first dose of IMP.
