Dose-Escalation Study to Assess the Safety, Tolerability, and Pharmacokinetics of Donepezil From Single Dose of GB-5001 IM Depot and Aricept® Oral Tablets in Healthy Male Volunteers

Phase 1
Completed
Conditions
Alzheimer Disease
Interventions
Drug: Placebo
Drug: Oral cohort
Registration Number
NCT05525780
Lead Sponsor
G2GBio, Inc.
Brief Summary

This study is to evaluate the safety and tolerability of single dose of GB-5001 (donepezil) IM depot in healthy male volunteers. And, it is to predict the multiple-dose pharmacokinetics based on the single-dose pharmacokinetics of GB-5001 IM depot and the oral Aricept® (donepezil hydrochloride) tablet by PK modeling.

  • Known risk of developing ulcers (for example, if you are taking non-steroidal anti-inflammatory drugs [NSAIDS] or high doses of acetylsalicylic acid [ASA] [Aspirin®]), unless determined as not clinically significant by the PI/Sub-Investigator.
  • Clinically significant history or presence of any clinically significant gastrointestinal pathology (e.g., chronic diarrhea, inflammatory bowel disease), unresolved gastrointestinal symptoms, or other conditions known to interfere with the absorption, distribution, metabolism, or excretion of the drug experienced within 7 days prior to study drug administration, as determined by the PI/Sub-Investigator.
  • Presence of any clinically significant illness within 30 days prior to dosing, as determined by the PI/Sub-Investigator
  • Presence of any clinically significant illness within 30 days prior to dosing, as determined by the PI/Sub-Investigator.
