Tebipenem (SPR994) Tissue Penetration in Diabetic Patients With Wound Infections and Healthy Volunteers Via In Vivo Microdialysis

Diabetes Clinical Trial

Official title: Pharmacokinetics and Soft-Tissue Penetration of Tebipenem (SPR994) in Healthy Volunteer Subjects and Diabetic Patients With Lower Limb Infections

Status Completed

Clinical Trial Summary

This study will determine the tissue penetration of a broad-spectrum orally bioavailable carbapenem, tebipenem pivoxil hydrobromide (SPR994) (Spero Therapeutics, Inc.), into the extracellular, interstitial fluid of soft tissue in diabetic patients with lower limb wound infections. Penetration will be compared with a group of healthy volunteer control participants.

Clinical Trial Description

This study will enroll 10 patients with diabetes who are admitted with a lower limb wound infection and 6 healthy volunteer control participants. The study will take place in an inpatient unit at Hartford Hospital for all patients and in the Clinical Research Center at Hartford Hospital for all healthy volunteers. All participants will receive 3 to 7 doses of tebipenem pivoxil hydrobromide (300 mg or 600 mg orally every 8 hours depending on renal function). A microdialysis probe (Mdialysis Inc., N. Chelmsford, MA) will be inserted into the subcutaneous soft tissue near the margin of the wound (patients) or in the thigh (healthy volunteers). The microdialysis probe is perfused with normal saline solution and samples are collected for the 8 hours following the final dose. A peripheral intravenous catheter will be inserted into an arm vein to collect blood samples simultaneously with microdialysis samples. Concentrations in tissue are compared with blood to determine percent penetration. ;
