| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial | The primary objective of this study is to assess the effects of duloxetine 40 mg twice
daily (BID) in women with urodynamically proved stress urinary incontinence (SUI) on
the within-group change in vesical Valsalva leak point pressure (VLPP) from baseline to endpoint (4 weeks). | |
| E.2.2 | Secondary objectives of the trial | | To evaluate the within-group endpoint/baseline ratios of Root Mean Square Voltage and Mean Rectified Voltage from the rhabdosphincter electromyogram at rest and with coughing, and the ratio of cough/rest ratios from baseline to endpoint (4 weeks). To evaluate the within-group changes in VLPP and ratios of EMG variables from baseline to 6 months and from 4 weeks to 6 months. To describe the percent change in IEF (incontinence episode frequency) from baseline to postbaseline and define two groups, responders and non-responders, based on the threshold value of <50% IEF reduction values. To compare the changes in VLPP and in EMG ratios from baseline to 4 weeks and from baseline to 6 months in responders and non-responders. To evaluate the safety and tolerability of duloxetine 40 mg BID for up to 28 weeks in subjects diagnosed with urodynamic stress incontinence (USI). Safety and tolerability will be evaluated based on TEAEs, discontinuation rates, vital signs, and laboratory analyses. | |
| E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
| E.3 | Principal inclusion criteria | Subjects may be included in the study only if they meet all of the following criteria:
[1] Are female outpatients.
[2] Are ≥18 and ≤75 years of age.
[3] Have a diagnosis of only stress urinary incontinence (SUI)
(urodynamic stress incontinence [USI] with normal compliance and no
detrusor overactivity [DO]) confirmed on urodynamic studies (UDS)
(determined at Visit 2; see Section 3.2.2.1) and a positive Valsalva
leak point pressure (VLPP).
[4] Have discrete episodes of incontinence (that is, are dry between
episodes and not continuously leaking urine), synchronous with
increased abdominal pressure from coughing, sneezing, exercising,
etc. An episode is defined as an easily noticeable leakage of urine that
would wet a pad, containment garment, or article of clothing.

difficulty.
[6] Have no language or cognitive barriers, agree to comply with the
requirements of the protocol, and sign a written informed consent
document (ICD) prior to entry into the study.
[7] Are women of non-childbearing potential by reason of hysterectomy,
other surgery, or natural menopause, or are women of childbearing
potential agreeing to use a medically accepted means of contraception
(for example, intrauterine device [IUD], oral or injectable
contraceptives, implant, barrier device, sterilization, abstinence, or sex
with a vasectomized male partner) for the duration of the study.
Women using oral contraceptives or hormone replacement therapy
must have a stable dose and regimen for ≥3 months prior to entry into
the study.
[8] Have no pelvic organ prolapse protruding more than 1 cm beyond the
hymen (Bump et al. 1996). | |
| E.4 | Principal exclusion criteria | [9] At Visit 1, have a positive urine culture (>100,000 cfu/mL), or a history of four or more urinary tract infections in the preceding year.

nervous system (CNS) abnormalities that affect the lower urinary tract.
[11] Suffer from severe constipation (have a history of fecal impaction or
have impacted rectum at time of physical examination despite recent
evacuation).

and/or frequency has not been stable for at least 3 months prior to
randomization, or is anticipated to change during the course of the
study.
[13] Have had urethral surgery (for example, diverticulectomy, urethral
dilations, or bulk injections).
[14] Have had more than one continence surgery.
[15] Have had any major surgery or continence surgery within 6 months
prior to study entry.
[16] Have current diagnosis of any of the following conditions, disorders,
or diseases of the genitourinary tract: a. Ureteric, bladder, urethral, or rectal fistula;
b. Uncorrected congenital abnormality leading to urinary incontinence; c. Adult enuresis or voiding difficulty.
[17] Use any of the following currently or at any time during the study:
a. Any anti-incontinence device including tampons used to prevent incontinence
b. Any medication in the list of excluded medications

nonpharmacologic (such as electrostimulation, vaginal cones, or any
device) intervention for incontinence or prolapse within 3 months prior
to study entry or throughout the study.
[19] Began pelvic floor muscle exercises within 6 months prior to study entry. Subjects who regularly perform pelvic floor muscle exercises cannot change their
exercise regimen during the course of the study.
[20] Have current or past urogenital cancer.
[21] Have any condition, limitation, disease, or abnormal laboratory value
that could, in the judgment of the investigator, preclude evaluation of
response to duloxetine.
[22] On physical examination, have neurological and/or vaginal
examination results that, in the opinion of the investigator, should
exclude the subject.
[23] Are known to have increased intraocular pressure or to be at risk for
acute narrow-angle glaucoma.
[24] Have a symptomatic arrhythmia despite antiarrhythmic medication.
[25] Have current angina or any active cardiac ischemic condition,
including myocardial infarction, within 6 months prior to study entry.
[26] Have uncontrolled or poorly controlled hypertension.
[27] Have active seizure disorder.
[28] Have unstable diabetes mellitus.
[29] Have a known hypersensitivity to duloxetine or any of the inactive
ingredients.
[30] Have a history of severe allergies, including drug allergies, requiring
emergency medical treatment or have multiple and/or severe adverse
drug reactions.
[31] Have a history of ongoing episodic lung disease associated with four
or more acute exacerbations of severe coughing per year.

study entry; subjects who report regular consumption of >=21 alcoholic
drinks per week (an average of 3 drinks per day) will be excluded.
[38] Have previously entered any study investigating duloxetine.
[39] Are investigator site personnel directly affiliated with the study, or are
immediate family of investigator site personnel directly affiliated with
the study. Immediate family is defined as a spouse, parent, child, or
