Evaluation of Penetration of Ceftobiprole Into Soft Tissue Determined by Microdialysis in Healthy Volunteers

An Exploratory Study to Evaluate the Penetration of Ceftobiprole Into Soft Tissue Determined by In Vivo Microdialysis in Healthy Volunteers

• Status: Completed
• Phase: Phase 1
• Study type: Interventional
• Enrollment: 15 (actual)
• Sponsor: Basilea Pharmaceutica · Industry
• Sex: All
• Age: 18 Years – 55 Years
• Healthy volunteers: Not accepted

Summary

The primary objective of this study is to measure the penetration of ceftobiprole into subcutaneous (s.c.) adipose tissue and skeletal muscle and to determine the concentration over time of ceftobiprole in these tissues and in plasma after administration of a single intravenous (i.v.) infusion (directly into the vein) of ceftobiprole 500 mg administered over 2 hours. The secondary objective was to further assess the safety and tolerability of ceftobiprole after a single i.v. infusion.

Detailed description

This is a single-center, open-label (all patients involved know the identity of the drug), single-arm, nonrandomized study of ceftobiprole in healthy men and women. The study is conducted in 2 parts: a pilot study and a main study. Each study (i.e. the pilot study and the main study) consists of 3 phases: a pretreatment phase that includes up to a 21-day screening period, an open-label treatment phase (1 day in the pilot study and 2 days in the main study), and a posttreatment phase that included the end of study evaluations and follow-up study visit or telephone contact planned for 1 to 2 weeks after discharge from the study unit. Serial blood and dialysis samples will be collected at specified time points from predose through 24 hours after the start of the infusion for estimation of ceftobiprole and ceftobiprole medocaril concentrations. Additional samples will be collected for measurement of protein binding. The study will include the following evaluations of safety and tolerability: adverse events, clinical laboratory tests (including hematology, serum chemistry, and urinalysis), electrocardiogram (ECG), vital signs, physical examination, serology, pregnancy tests, urine drug screen, and alcohol breath test. In the pilot study, Ceftobiprole will be locally administered via a microdialysis probe at a concentration of approximately 30 µg/mL for 60 minutes. In the main Study, each volunteer will receive ceftobiprole locally via the microdialysis probe. After the washout period determined by the pilot study, each volunteer will receive a single 2-hour i.v. infusion of ceftobiprole.
