COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Each participant will receive a single oral dose of BNC210. The dose will be administered as a suspension in 10 mL of vehicle. The starting dose will be 5 mg, with 3-fold escalations up to 150 mg, which will be doses of 5, 15 and 50 mg and 150 mg, then 2 fold escalations thereafter with doses of 300, 600 and 1200 mg.
Intervention code [1] 236883 0
Treatment: Drugs
Comparator / control treatment
placebo - the placebo will be 10 mL of the liquid vehicle minus the active ingredient and will be taken as a single oral dose
Control group

Primary outcome [1] 238304 0
To determine the pharmacokinetics of single doses of BNC210. Plasma and urine samples will be collected for pharmacokinetic assessment. The samples will be assayed by a validated Liquid Chromatography/Mass Spectrometry (LC/MS) method which is specific for the determination of BNC210
Timepoint [1] 238304 0
from baseline to 32 hours post dose
Primary outcome [2] 238305 0
To determine the clinical tolerability of single doses of BNC210. This will be assessed using scheduled adverse event probes, spontaneous adverse event reporting, physical examination, routine laboratory investigations, Electrocardiogram (ECG) and vital sign evaluations plus clinical chemistry analysis (haematology, biochemistry, urinalysis)
Timepoint [2] 238305 0
from baseline to 8 days (+/- 3 days ) post dosing
Secondary outcome [1] 244696 0
To determine the effects of BNC210 on neurological and psychiatric symptoms using Bond and Lader visual analogue scales.
Timepoint [1] 244696 0
from baseline to 32 hours post dose
Secondary outcome [2] 244697 0
To identify a dose range to be used in subsequent trials.
Timepoint [2] 244697 0
from baseline to 8 days (+/- 3 days ) post dosing

Key inclusion criteria
1. Good general health without clinically significant renal, hepatic, cardiac or respiratory disease, as determined by the principal investigator.
2. Good general mental health as determined by scores on the Symptom Checklist-90-R (SCL-90-R (registered trademark)), a screening instrument which evaluates a broad range of psychological problems and symptoms of psychopathology.
3. Agree to and be capable of signing informed consent form.
4. Have suitable venous access for blood sampling.
5. Body Mass Index within the range of 19-30 kg/m2.
Minimum age
18 Years
Maximum age
65 Years
Can healthy volunteers participate?
Key exclusion criteria
1. Renal impairment as evidenced by estimated creatinine clearance, measured by the Cockcroft-Gault method of less than 90 mL/min.
2. Have a laboratory value at the Screening Visit that is outside the normal range, unless it is judged by the Investigator as not clinically significant after appropriate evaluation.
3. A score of more than two standard deviations from the mean on any of the key nine scales in the SCL-90-R (registered trademark)
4. Any medical condition that in the opinion of the investigator may adversely impact on the participant’s ability to complete the study.
5. Plasma Aspartate transaminase (AST), Alanine transaminase (ALT), and Alkaline phosphatase (ALP) tests in excess of 1.5 times the upper limit of normal.
6. History of severe allergic or anaphylactic drug-related reactions.
7. Current (within the last six months) clinically significant psychiatric disorder including anxiety or depression.
8. Concurrent use of other medication on a regular or daily basis.
9. Participation in another clinical trial of an investigational agent within 30 days of study entry.
10. Known history of past or present infection with hepatitis C virus (HCV), hepatitis B or human immunodeficiency virus (HIV).
11. Clinically significant abnormal electrocardiogram (ECG) (12-lead) at the screening visit or prior to dosing on Day 1, as determined by the Investigator.
12. Subjects who have a marked prolongation of the QT corrected (QTc) interval (i.e., repeated demonstration of a QTc interval >450 msec for females or >430 msec for males) at screening or prior to dosing on Day 1 will not be allowed to continue in the study.
13. Significant history of illicit drug or alcohol use or abuse (as determined by the Investigator) within 1 year of the Screening Visit.
14. Any alcohol use within 24 hours prior to dosing on Day 1.
15. Unwillingness or inability to comply with the requirements of this protocol, including the presence of any condition (physical, mental, or social) that is likely to affect the subject's returning for follow-up visits on schedule.
16. Blood donation (1 unit or more) within 1 month prior to the screening visit.
17. Smoke >5 cigarettes per day.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be entered into the study sequentially and will be randomly allocated to active drug or placebo using a randomisation table created by computer software. In order to maintain the blinding of subject treatment assignments all study site personnel (with the exception of the Pharmacist or designee who is responsible for preparing the study treatment) will be blinded to treatment assignment. All study site personnel performing subject assessments will not be informed of the subject’s treatment assignment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation -an electronically generated randomisation code created by computer software which will be supplied to the sponsor-contracted pharmacist by the CRO. The pharmacist will number the drug doses so that the allocation of subjects to placebo or active dose will be concealed from the clinical trial site personnel

Brief summary
This is a phase I trial to assess the safety and tolerability of a new anti-anxiety drug over a wide range of doses. This will enable doses, that are safe and produce good levels of drug in the body, to be selected for further studies in which measurement of anti-anxiety activity may be done.
