Safety of Intravenous Apramycin in Adults

A Phase I, Open-label Study to Assess Lung Pharmacokinetics and Safety of a Single Dose of Apramycin Administered Intravenously in Healthy Adult Subjects

• Status: Completed
• Phase: Phase 1
• Study type: Interventional
• Enrollment: 16 (actual)
• Sponsor: National Institute of Allergy and Infectious Diseases (NIAID) · NIH
• Sex: All
• Age: 18 Years – 45 Years
• Healthy volunteers: Accepted

Summary

A Phase I, open label study of a single dose of 30 mg/kg of apramycin administered intravenously (IV) over 30 (+/- 5) minutes. Twenty subjects will be enrolled in the study to one of 5 cohorts, T1-T5, each corresponding to a timepoint after initiation of infusion at which a single fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) is performed. There will be 4 subjects per cohort. Cohort T5 will be enrolled after plasma and lung apramycin concentrations and preliminary PK data analysis are completed in cohorts T1-T4. Enrollment and dosing will be determined by bronchoscopy schedule. For each cohort, if 2 subjects are scheduled to receive study drug on the same day, the dose will be administered sequentially at least 2 hours apart. The primary objective is to assess plasma pharmacokinetic (PK) profile of apramycin and lung penetration of apramycin in epithelial lining fluid (ELF) and alveolar macrophages (AM) after single intravenous (IV) apramycin dose of 30 mg/kg in healthy subjects.

The primary objective is to assess plasma pharmacokinetic (PK) profile of apramycin and lung penetration of apramycin in epithelial lining fluid (ELF) and alveolar macrophages (AM) after single intravenous (IV) apramycin dose of 30 mg/kg in healthy subjects. The secondary objectives are to 1) assess the safety of single IV administration of 30 mg/kg apramycin in healthy subject and 2) to assess changes in otoacoustic testing.
