CLINICAL TRIALS PROFILE FOR TOBRAMYCIN SULFATE

All Clinical Trials for tobramycin sulfate

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT01938417 ↗	Tobramycin Exposure From Active Calcium Sulfate Bone Graft Substitute	Completed	University of Lausanne Hospitals		2006-10-01	This study aimed to assess the systemic absorption and disposition of tobramycin in patients treated with a tobramycin-laden bone graft substitute (Osteoset® T).
NCT03308253 ↗	Study for Antibiotic Impregnated Calcium Sulfate Beads as Prophylaxis for Surgical Site Infection	Unknown status	McMaster University	Phase 4	2018-07-16	The CDC quotes a rate of wound infection of 2-5% for inpatient surgery. Patients undergoing a vascular operation, however, are generally at an increased risk of wound infection with rates often close to 5-10%.
