This is an interventional basic science trial for Urinary Tract Infections focused on measuring UTI, Bacteriophage, Phage Read More

Inclusion Criteria:

1. Provision of signed and dated informed consent form.
2. Stated willingness to comply with all study procedures and availability for the duration of the study.
3. Males or females 18 years of age or older.

4. Patients with a lower urinary tract colonization caused by E. coli (≥10^3 CFU/mL) and who meet at least one of the following criteria:

   • Has an indwelling urinary catheter and medical documentation of a urinary tract infection by E. coli within the past 12 months
   • Requires intermittent catheterization and medical documentation of a urinary tract infection by E. coli within the past 12 months
   • Has medical documentation of a history of asymptomatic bacteriuria (i.e., lower urinary tract colonization) with E. coli at least once in the past 12 months
5. Patients must have experience with urinary catheterization or have Medical Monitor approval if the patient does not have prior experience with catheterization.
6. In good general health as evidenced by medical history and physical examination.
7. Women of childbearing potential and men with female partners of childbearing potential must use two forms of effective contraception, at least 1 of which is a physical barrier method, during the study and which is recommended to continue for 2 weeks after completing the study.

Exclusion Criteria:

1. Patients with clinical signs of active UTI or other infection requiring antimicrobial treatment. These may include dysuria, urinary frequency, urinary urgency, suprapubic discomfort and flank pain in addition to non-specific symptoms of urinary leakage, change in voiding habits, worsening muscle spasm, increasing autonomic dysreflexia, sweating, malaise, and fever or hypothermia. Analgesic use is permitted.

2. Patients who have received Gram-negative bacteria antimicrobials within 14 days of randomization.

   Note: Patients who are currently only receiving antibiotics with only Gram-positive activity (e.g., vancomycin, daptomycin, linezolid) to treat active infections against Gram-positive non-UTIs can be included in the trial.

3. Presence of a surgically-modified bladder, except for a repaired ruptured bladder.
4. History of severe autonomic dysreflexia, which is defined as those patients who have a spinal cord injury and who have had a documented sudden increase in systolic blood pressure of greater than 40 mm Hg due to an irritation or stimulation (including bladder or bowel irritation) below the level of the spinal cord injury. Autonomic dysreflexia can include findings of hypertensive crisis or emergency, clinically significant bradycardia/tachycardia, severe headache or other severe reaction requiring an acute intervention, so consultation with the Medical Monitor should take place if a history of severe autonomic dysreflexia is suspected but not clearly identified.
5. Active severe, progressive or uncontrolled renal, hepatic, hematologic, gastrointestinal, endocrine, pulmonary, cardiac, or neurologic disease per the investigator's discretion.
6. Any malignancies within the past 5 years (except those in remission).
7. Unless deemed acceptable by the Investigator, prescription drugs, over-the-counter (OTC) medications and supplements that acidify the urine are excluded.
8. Patients who have had allergic reactions to similar compounds, or any excipients.
9. Participation in an investigational drug or device study within 1 month (or 7 half-lives of drug, whichever is longer) prior to randomization.
10. Patients who are pregnant or expecting to conceive, are breast feeding or are planning to breast feed, within 1 month of completion of the study.
