Condition(s) targeted: Pseudomonas Infection

Intervention: Fosfomycin tromethamine (Drug); Fosfomycin disodium (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: National Institute of Allergy and Infectious Diseases (NIAID)

Summary

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.

Clinical Details

Official title: A Randomized, Safety, Tolerability and Pharmacokinetics 3-Period Crossover Study Comparing 2 Single Doses of ZTI-01 and Monurol« in Healthy Subjects

Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Assessed safety and tolerability via physical examinations, vital signs, standard 12-lead electrocardiograms, and clinical laboratory tests

Pharmacokinetics: Volume of distribution (Vd) or apparent volume of distribution (Vd/F) as appropriate, clearance (CL) or apparent Clearance (CL/F) as appropriate, renal Clearance (CLr) and Fraction Bioavailable as appropriate

Pharmacokinetics: Maximum measured plasma concentration (Cmax), area under the concentration versus time curve (AUC0-t and AUC0-inf), time to peak concentration (tmax), terminal elimination half-life (t1/2), terminal-phase elimination rate constant).

Adverse events (AEs) will be monitored and recorded

Detailed description: This is a Phase 1 single-dose, randomized, 3-Period, crossover study conducted at a single center. A total of 30 healthy subjects, aged 18-45years, will be randomized to receive one of 3 treatment sequences. The duration of study will be approximately 18-26 days and subject participation will be the duration of study. Each treatment sequence will be enrolled in parallel and each subject will receive all 3 treatments in crossover fashion. Each subject will complete Screening, Baseline, and Treatment Phases. The Screening Phase will be

conducted on an outpatient basis within 35 days of admission (Day - 1 of Period 1). All

subjects admitted to the study center the day before dosing in each treatment period (Day

- 1; check-in) for pre-dosing assessments and will remain in the study center through 48

hours post-dose for each Period. Final baseline qualification will only be evaluated prior to randomization for Treatment Period 1. Each one of the periods will be separated by a 3 (minimum) to 7 days (maximum) washout period. The Treatment Phase will be comprised of 3 crossover periods (duration Day-1 to 48 hours post dose). Each crossover period will include a single dose of study drug under fasting conditions followed by post-dose safety assessments and blood and urine collection for PK measures through 48 hours post-dose; each period will be separated by a 3 to 7 days washout. Subjects will remain in the study center

for all 3- study treatment periods (Day - 1 to 48 hours post dosing) and will be discharged

after the 48-hour sampling timepoint (if safety parameters are acceptable to the Investigator on Day 3).

Eligibility

Minimum age: 18 Years. Maximum age: 45 Years. Gender(s): Both.

Criteria:

Inclusion Criteria: To be considered for study enrollment, subjects must meet all of the inclusion criteria:

- Healthy men and women from 18 to 45 years of age with no clinically significant

findings on medical history, physical examination, vital signs, 12-lead electrocardiogram (ECG) or clinical laboratory evaluation that were performed at

Screening and Day - 1.

post-menopausal range as well as surgically sterile women (documented history of oophorectomy and/or hysterectomy, tubal ligation or tubal occlusion) will be eligible.

- Females of childbearing potential must use an acceptable birth control method (e. g.,

condom plus spermicide, combined oral contraceptive, implant, injectable, indwelling intrauterine device, sexual abstinence, or a vasectomized partner) throughout the study and for 4 weeks following initiation of dosing with study drug.

- Male subjects must either had a vasectomy or agree to use a double barrier method of

contraception, condom plus spermicide (or diaphragm plus spermicide in female partner) from the time of dosing with the study drug in Period 1 through 4 weeks following initiation of dosing with study drug.

- Nicotine-free by history (cigarettes, pipe, cigar, chewing tobacco, nicotine patch)

- 1 <400 ng/mL).

- Able to abstain from grapefruit, grapefruit juice, grapefruit-containing products or

alcoholic beverages within 48 hours before Day - 1 and throughout the inpatient

period.
