The TRIUMPH study is a randomized, double-blinded, 3-arm, parallel-group trial designed tocompare the effects of anticholinergic bladder therapy versus a) beta-3-adrenergic agonistbladder therapy and b) no bladder pharmacotherapy on cognitive, urinary, and other aging-related functional outcomes in ambulatory older women with urgency-predominant urinaryincontinence and either normal or mildly impaired cognitive function at baseline.
134 studies on the registry are indexed under Nocturia; 22 are open to participants now.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

Tolterodine tartrate is a muscarinic receptor antagonist designed to treat urgency incontinence, urgency, and frequency associated with overactive bladder. Behavioral self-management education includes written education about timed urge suppression
Drug: TolterodineTartrate ER
Mirabegron, currently sold under the brand name Mybetriq by Astellas Pharma, is a selective beta-3-adrenergic receptor agonist approved for treatment of urgency urinary incontinence, urgency, and frequency associated with overactive bladder. Behavioral self-management education includes written education about timed urination, lifestyle changes, pelvic floor muscle exercises, and urge suppression.
Drug: Mirabegron
Microcrystalline cellulose placebo encapsulated to appear identical to tolterodine and mirabegron medication will be prepared by a compounding pharmacy. Behavioral self-management education includes written education about time duration, lifestyle changes, pelvic floor muscle exercises, and urge suppression.
Drug: Placebo

Change in nocturnal urination frequency over 6 months (24 weeks) of treatment, based on a validated voiding diary.
Frequency of nocturnal urination will be assessed using a standardized, 7-day voiding diary.
Time frame: Baseline to 6 months
Change in nocturnal urinary incontinence frequency over 6 months (24 weeks) of treatment, based on a validated voiding diary.
Frequency of nocturnal urination will be assessed using a standardized, 7-day voiding diary.
Time frame: Baseline to 6 months
Change in global sleep quality score over 6 months (24 weeks) of treatment.
Perceived sleep quality will be assessed using the Pittsburgh Sleep Quality Index(PSQI), an 18-item validated questionnaire designed to assess sleep quality, latency, efficiency, and problems over a one-week period. Score range: 0-21, with higher scores indicating a worse outcome.
Time frame: Baseline to 6 months
Change in daytime sleepiness score over 6 months (24 weeks) of treatment.
Daytime sleepiness will be assessed using the Epworth Sleepiness Scale (ESS), an 8-item questionnaire assessing the level of general sleepiness during real-life situations in order to distinguish excessive daytime sleepiness from normal daytime sleepiness. Score range: 0-24, with higher scores indicating a worse outcome.
Time frame: Baseline to 6 months
Change in sleep efficiency over 6 months (24 weeks) of treatment, based on the PSQI sleep efficiency score.
Sleep efficiency will be assessed based on questions 1, 3, and 4 of the Pittsburgh Sleep Quality Index (PSQI). Score range: 0-3, with higher scores indicating a worse sleep efficiency.
Time frame: Baseline to 6 months
Change in depression symptoms over 6 months (24 weeks) of treatment.
Depression symptoms will be assessed using the 15-item short form of the GeriatricDepression Scale-15 (GDS-15), which assesses symptoms of depression over a 1-week period. Score range: 0-24, with higher scores indicating a worse outcome. Score range: 0-15, with higher scores indicating a worse outcome.
Time frame: Baseline to 6 months
Change in anxiety symptoms over 6 months (24 weeks) of treatment.
Anxiety symptoms will be assessing using the Generalized Anxiety Disorder-7 (GAD7),7-item short form, questionnaire to assess severity of anxiety symptoms over a 2-week period. Score range: 0-21, with higher scores indicating a worse outcome.
Time frame: Baseline to 6 months
Change in composite cognitive function over 6 months (24 weeks) of treatment, using a composite cognitive score that incorporates normalized data from all domain-specific cognitive tests.
The composite cognitive score will be calculated as the average of Z-scores from the following individual cognitive tests: a) Auditory Verbal Learning Test (AVLT); b) Oral Trail Making Test (OTMT) part A; c) OTMT part B; d) Digit Span Test; and e) Digit Symbol Substitution Test (DSST). The normative mean of each cognitive test will be subtracted from each participant's component test score, and this difference will be divided by the standard deviation for the appropriate normative sample. After scores from individual tests are transformed to Z scores as a common metric based on normative data, the average Z score from all available tests will be calculated to provide a composite Z score.
Time frame: Baseline to 6 months
