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. |

NCT03697993 ↗ | Safety and Efficacy Study of Oral Fosfomycin Versus Oral Levofloxacin to Treat Complicated Urinary Syndromes (FOCUS) | Terminated | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 4 | 2018-11-07 | This is a Phase 4, multi-center, open-label, randomized pragmatic superiority clinical trial comparing two strategies for initial or step-down oral therapy for complicated urinary tract infections (cUTI) after 0-48 hours of parenteral antibiotic therapy. The trial will evaluate the success and safety of a strategy of initial or step-down fosfomycin, administered at a dose of 3 g once daily, vs. a strategy of initial or step-down levofloxacin administered at a dose of 750 mg once daily. Investigator-directed adjustment to another adequate oral therapy is allowed 1) if the causative pathogen is not susceptible in vitro to quinolone initial or step-down therapy in a subject randomized to the levofloxacin strategy, OR 2) if the subject develops an intolerance or allergy to the initial step-down oral therapy and at the investigator's discretion, OR 3) the subject has an underlying condition posing increasing risk for adverse events from quinolone therapy. The duration of oral therapy (initial + investigator-directed adjustment if indicated) in each strategy is 5-7 days of any per protocol antibiotic to which the pathogen is susceptible. The dosing of oral therapy depends on creatinine clearance (CrCl). The trial will enroll approximately 634 patients that are either male or female aged 18 or older with cUTI from outpatient and inpatient settings. The study will take place over 25 months in up to 15 US sites. The primary objective is to compare Strategy 1 and Strategy 2 in terms of treatment success rates at Test of Cure (TOC). |
