Acute Ischemic Stroke Clinical Trial
Official title:
A Single-Center, Randomized, Placebo-Controlled, Single Ascending Dose Trial to Evaluate the Safety, Tolerability, and Pharmacokinetics of Intravenous Nts-104 Tris in Healthy Adults
NTS-104 TRIS will be administered as a single intravenous dose to healthy subjects at doses of 0.8, 4, 8 and 16 mg/kg in 4 Cohorts. Each cohort of 8 subjects will begin with dosing 2 sentinel subjects with one being given the investigational product and one the placebo. If no safety issues arise, dosing the remaining subjects in the cohort will begin. A Safety Review Committee will review the safety and pharmacokinetic data before approving escalation to the next dose level.

Any active or current comorbidity with the exception of topical or allergic conditions treated with topical comedication and/or non-drowsy anti-allergic medication or acetaminophen 3. Any use of current comedication at admission or during the 30 days prior to enrollment with the exception of topical dermatological medication and/or non-drowsy anti-allergic medication or acetaminophen 4.

Specifically, any history or current diagnosis of renal impairment at screening 9. Specifically, a history of type 1 diabetes mellitus or current type 2 diabetes. 10. Any abnormality on the neurological examination, at screening or enrollment 11. Positive Columbia-Suicide Severity Rating Scale (C-SSRS). 12. Participation in another clinical trial with drugs received within 3 months prior to dosing (calculated from the previous study's last dosing date). 13. Participant who is an active smoker and/or has smoked or used nicotine or nicotine- containing products (e.g., nicotine patch, gum, e-cigarettes) within the past 6 months before enrollment. 14. The use of ketogenic diets within 12 months prior to enrollment. 15. Electrocardiogram (ECG) with clinically significant findings recorded at screening or admission. 17. Positive coronavirus disease 2019 (COVID-19) test determined at screening and admission (nasal swab). 18. Known history of alcohol or drug abuse in the past 5 years. 19. Positive urinary drug or cotinine screen determined at screening and admission. 20. Positive serum alcohol screen determined during the screening period and on admission. 21. Any other condition, which in the Investigator's opinion, would not make the participant a good candidate for the study. 22. Blood donation of 500 mL (1 pint) or more: 56 days before the screening visit and until after the follow-up visit. 23. Plasma donation: 7 days before the screening visit and until after the follow-up visit. 24. Grapefruit, grapefruit juice, star fruit, pomegranate, and Seville oranges: 7 days before screening and until after the follow-up visit |
