About
The present study is designed to assess the safety and tolerability of escalating, multiple ascending doses of Cavosonstat (N91115) in healthy subjects.
Full description
This study will assess the safety and tolerability of escalating, multiple ascending doses of Cavosonstat (N91115) in healthy subjects.
Approximately 5 ascending cohorts are planned with approximately 8 subjects per cohort (6 active, 2 placebo). Each subject will undergo screening (Day -28 to Day -2) and, if eligible, return to the unit on Day -1 when eligibility will be reconfirmed.
Eligible subjects will be randomized in a 3:1 ratio to receive investigational medicinal product (IMP) N91115 (daily [QD] or every 12 hours [Q12H]) or matching placebo (QD or Q12H) for 7 days and will be followed for safety while housed in the clinical research unit (CRU) until discharge on Day 8. Pharmacokinetics will be followed from Study Day 1 through the morning of Study Day 8. The subjects will be discharged from the CRU and complete the post treatment withdrawal phase, including a follow-up phone call on Day 15.

Unifocal couplets: > 20 / hour iii. Complex of multifocal singlets: > 50 / 24 hours iv. Complex of multifocal couplets: > 10 / 24 hours v. Any Run (ventricular tachycardia) c. Heart rate i. < 40 bpm for 1 minute while awake ii. < 35 bpm for 3 minutes while asleep iii. > 120 bpm for 3 minutes (when not exercising) iv. Pauses > 2000 msec d. 2nd or 3rd degree AV block e. Intraventricular conduction delay (IVCD) with QRS duration > 120 msec or right bundle branch block (RBBB) or left buddle branch block (LBBB) other than rare RBBB f.

Disorder that would interfere with the absorption, distribution, metabolism, or excretion of drugs as determined by the investigator
History of alcohol abuse or drug abuse (including cannabis, cocaine, and opioids) in the year prior to screening
Positive alcohol test at screening or Day -1.
Positive drug test (including but not limited to cocaine, amphetamines, barbiturates, opiates, benzodiazepines) at screening or Day -1.
a. A positive drug test for cannabinoids at screening will be allowed if the subject agrees to abstain from use of all forms of cannabinoids during screening and throughout the study and has a negative test at Day -1
Positive screening test for Hepatitis B surface antigen, Hepatitis C antibody, or human immunodeficiency virus (HIV) antibody.
Unwilling to limit consumption of coffee and caffeine-containing foods and beverages from Day -1 until discharge on Day 8.

Use of vitamins from Day -7 until end-of-study follow up call, and use of over-thecounter (OTC) medications, prescription medications, or herbal remedies from Day - 14 until end-of-study follow-up call. By exception, acetaminophen ≤ 1000 mg/day is permitted except within 48 hours prior to Day -1. Hormone replacement therapy (HRT) and hormonal contraception is allowed throughout the study. The Medical Monitor and Principal Investigator may allow certain OTC medications by exception if they are not likely to affect study conduct and output.
