Summary
This is a multi-center, double-blind, placebo-controlled study with two weeks of daily oral administration of one of three dose levels of Paxerol or placebo in subjects with nocturia. Eligible study subjects will be identified according to inclusion/exclusion criteria (see below), and baseline assessments will be recorded.
Due to small sample size of 25 patients per group in this proof-of-principle dosing-finding trial, stratification according to gender and BMI will be difficult. However, similar distribution of patient types to the four treatment groups will be attempted by evenly assigning patients to the four treatment groups according to genders and body mass index (BMI) of <25, 25-30 and 30-40.
Paxerol or placebo will be taken 30 minutes before bedtime daily for two weeks. Nocturia frequency, Nocturia Quality of Life (NQOL), Duration of First Undisturbed Sleep (DFUS), total hours of nightly sleep, safety and tolerability will be monitored before and after a two-week treatment period. Results from subjects treated with different doses of Paxerol and placebo will be assessed and compared. Baseline urinary Prostaglandin E2 (PGE2) production will also be assayed to assess potential correlation between baseline urinary PGE2 production and responsiveness to Paxerol treatment.
Eligibility Criteria
Inclusion:
- Subjects diagnosed with nocturia, as defined by International Continence Society (i.e., the interruption of sleep one or more times at night to void), confirmed by evaluation in participating investigator's urology practice for the following characteristics: nocturia is related to overactive bladder (OAB); nightly ≥2.5 times nocturia present for at least 3 months and not considered caused by persistent or recurrent urinary tract infection; Post-Void Residual (PVR) urine volume must be 150/100 mm Hg).
- Serious medical illness, such as significant cardiac disease (e.g. symptomatic congestive heart failure, unstable angina pectoris, myocardial infarction within the past 6 months, uncontrolled cardiac arrhythmia, or New York Heart Association Class II, III or IV), severe debilitating pulmonary disease, or history of stroke (hemorrhagic or thrombotic), A-V malformation, or other cerebrovascular disease.
- Receipt of any investigational drug or participation in any clinical trial within 30 days prior to study participation.
- Use of acetaminophen, ibuprofen, acetylsalicylic acid (ASA) or any NSAID on the day of entry into the study or any anticipated use during the study. In the event of the need for any unanticipated use of such drugs during the trial, the timing and doses of such use should be carefully recorded and reported at the next visit to the clinic.
- Any medical problem requiring uninterrupted use of acetaminophen, ibuprofen, or any NSAIDs, or any other pain medication.
- Daily use of phosphodiesterase (PDE) inhibitors (such as sildenafil, tadalafil, vardenafil, avanafil, and udenafil) within 30 days prior to study or any anticipated daily use during the study. (Note: PDE inhibitors are known to have positive effect on voiding dysfunction and thus can interfere with the assessment of Paxerol [Ückert et al 2010].)
- History of polyuria or evidence of polyuria (estimation of daily production >2.5 liters of urine).
- Uncontrolled Type 1 or 2 diabetes mellitus (HbA1c >7.0%).
- Diabetes insipidus.
- Significantly impaired renal function (creatinine clearance <50 mL/min/1.73kg/m2)
- Any visual, motor or other sensory abnormality that might predispose to a fall on nocturnal arising to urinate.
- Evidence of hyponatremia at baseline.
- Any significant disease or abnormality of the neurological, visual, gastrointestinal, hepatobiliary, pulmonary, cardiovascular, genitourinary or musculoskeletal system other than those specified above that, in the opinion of the involved investigator, might compromise the ability of the prospective subject to participate in the study or that could confound interpretation of study results.
- Any abnormality on screening medical history, physical examination or clinical laboratory examination other than those specified above that, in the opinion of the involved investigator, might confound interpretation of study results.
- Subjects with known hepatitis, HIV-AIDS, or tuberculosis.
- Subjects with known dysrhythmia of any form.
