Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT02178254 ↗	Safety, Tolerability and PK 3-Period Crossover Study Comparing 2 Single Doses of ZTI-01 and Monurol® in Healthy Subjects	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	Phase 1	2014-08-01	The objective is to determine the safety, tolerability and pharmacokinetics (PK) of 2 single doses of ZTI-01 (1g and 8g infused over 1-hr) and a single dose of the Reference Label Drug, Monurol® (oral sachet, 3g). Subjects will be randomized to a treatment sequence prior to dosing on Day 1 of Period 1 prior to study screening.
NCT02570074 ↗	PK/PD and Safety/Tolerability of Two Dosing Regimens of Oral Fosfomycin Tromethamine in Healthy Adults	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	Phase 1	2016-01-01	Oral dosage regimens for fosfomycin tromethamine (Monurol™) are not established for the treatment of cUTI. The most common and recommended adult dosage regimen in the literature is a single-dose sachet containing the equivalent of 3 grams of fosfomycin administered every other day (QOD) for a total of three doses. There are a myriad of different oral fosfomycin dosing regimens currently being used in clinical practice, including up to 3 grams orally twice daily for 7-21 days, but these regimens are not based on solid pharmacokinetic, pharmacodynamic or safety rationale. Initial pharmacokinetic studies performed with oral fosfomycin tromethamine primarily examined single dose regimens and did not use modern day bioanalytical or pharmacokinetic techniques. As the use of fosfomycin becomes more pervasive in concordance with the increase in multidrug resistant pathogens, further pharmacokinetic and safety data are needed for more intensive dosing regimens to support its continued use. The rationale of this study is that oral fosfomycin tromethamine requires a modern pharmacokinetic-pharmacodynamic study to identify alternative oral dosage regimens that are appropriate and safe. This study provided safety/tolerability and clinical pharmacology information regarding two oral dosing regimens that may have application to treat various types of infections involving resistant pathogens or when other oral antibacterial options are not available.
