- Neurological lesion or condition, including cerebrovascular accident, spinal lumbar disc hernia, spinal cord injury, multiple sclerosis, Parkinson's disease, Guillain-Barré syndrome, pudendal, hypogastric or pelvic nerve lesion. Diabetes mellitus is allowed if controlled with or without medical treatment (e.g., HbA1C < 7%).
- Increased pelvic floor muscle activity during voiding (e.g., dyssynergic striated sphincteric activity/striated sphincteric activity during voiding, Fowler syndrome and pelvic floor muscle spasm).
- Previous bladder surgery (e.g., bladder augmentation or reduction surgery, latissimus dorsi detrusor myoplasty). Prior Benign Prostatic Obstruction surgery or pelvic organ prolapse surgery is allowed if performed more than 6 months prior to screening.
- Previous implant surgery for incontinence still in situ (e.g., tape, sling or artificial sphincter)
- Significant active urological pain syndrome.
- Previous pelvic radiation therapy.
- Dependence on use of a manual assistance method intended to improve bladder emptying (e.g., Credé's maneuver or suprapubic tapping).
Related to (previous or current) treatment and/or study drug:
Subject is receiving 1 or more of the following non-medication therapies:
- Electrostimulation therapy, e.g., neurostimulation/modulation or sacral nerve stimulation in the past 3 months.
- Intravesical or injection based treatment (e.g., botulinum toxin injections in urethra or bladder in the past 12 months).
- An ongoing bladder training program and/or pelvic floor muscle exercises, which started within 6 weeks prior to visit 1.
- Muscle-derived stem cell injection in the bladder or urethra or bladder transplantation at any time prior to screening.
- Subject is using prohibited medications or subject is using restricted medications under conditions different to those specified in the concomitant medication section.
- Subject has a known or suspected hypersensitivity to ASP8302 or any of the inactive ingredients.
Related to concomitant conditions:
(Please note that these exclusion criteria do not require specific diagnostic evaluation during the screening visit, unless the subject presents with signs and symptoms suggesting the presence of this condition that were not present earlier.)
- Subject is known to have inflammatory bowel disease or clinically significant diarrhea.
- Subject is known to be immunocompromised due to conditions such as human immunodeficiency virus/acquired immune deficiency syndrome or hepatitis C.
- Subject has been diagnosed with clinically significant cardiovascular or cerebrovascular diseases within 6 months prior to visit 1, such as myocardial infarction, uncontrolled angina/coronary artery disease, significant ventricular arrhythmias and heart failure (New York Heart Association class III/IV).
- Subject has been diagnosed with clinically significant asthma, chronic bronchitis and/or chronic obstructive pulmonary disease.
- Subject is known to have a mean Fridericia corrected QT interval (QTcF) > 430 ms for males or > 450 ms for females, a pre-existing long QT syndrome or hypokalemia.
- Subject has a clinically significant abnormal 12-lead ECG.
- Subject has current or previous malignant disease of the pelvis. Subjects with a history of (non-pelvic) cancer are considered eligible if the subject has undergone therapy and the subject has been considered disease free for at least 5 years. Subject with completely excised basal cell carcinoma or squamous cell carcinoma of the skin and completely excised cervical cancer in situ are also considered eligible.
- Subject is known to have moderate to severe hepatic impairment (i.e., Child-Pugh class B or C).
- Subject is known to have severe renal impairment defined as estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m^2.
- Subject is known to have current or history of alcohol and/or drug abuse within the last 24 months prior to screening.
- Subject has clinical signs and symptoms of a urinary tract infection (UTI), which is combined with a result of urine test (e.g., positive urine culture containing > 100,000 cfu/mL in midstream urine). If a UTI is confirmed in the visit 1 sample, the run-in period should be stopped. After successful treatment of the UTI, the subject can be rescreened and if eligible enroll in the study. If the subject has asymptomatic bacteriuria (i.e., a positive urine culture without clinical signs and symptoms of a UTI), the subject should not be excluded.
Subject has any of the following abnormal liver or kidney function parameters (as assessed in visit 1 sample):
- Alanine aminotransferase (ALT), aspartate aminotransferase (AST) or bilirubin increased to > 1.5 times the upper limit of normal (ULN).
- Gamma glutamyltransferase (γ-GT) increased to > 3 times the ULN.
- eGFR < 45 mL/min/1.73 m^2 based on the Modification of Diet in Renal Disease formula.
General:
- Subject has received investigational therapy within 28 days or 5 half-lives, whichever is longer, prior to screening.
- Subject is known to have any condition, which makes the subject unsuitable for study participation.
At visit 2:
- Subject meets any of the exclusion criteria of visit 1.
- Subject has severe overactive bladder (OAB), i.e., experienced 3 or more episodes of urgency (Patient Perception of Intensity of Urgency Scale (PPIUS) grade 3 or 4), during the 3-day micturition diary period prior to visit 2.

Measure Description |
Time Frame |
---|---|---|
Change From Baseline in PVR After Standardized Bladder Filling Measured by Catheterization (PVRc2) at Week 4
Time Frame: Baseline and week 4
|
Volume of urine in the bladder after standardized bladder filling measured by catheterization (PVRc2).
|
Baseline and week 4
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Voided Volume After Standardized Bladder Filling (VV_St) at Week 4
Time Frame: Week 4
|
VVst is thought to increase as the bladder emptying is improved.
Standardizing the bladder filling is thought to increase accuracy in comparison with normal spontaneous bladder filling which will differ between time points.
No multiplicity correction will be performed.
|
Week 4
|
Bladder Voiding Efficiency Calculated With PVRc2 and VV-St (BVEc2) at Week 4
Time Frame: Week 4
|
Bladder voiding efficiency (BVE) is defined as the percentage of the total bladder capacity (BC) that is voided using the following formula: BVE = [volume voided (VV) / (PVR + VV)] x 100.
BVEc2: BVE calculated for PVRc2 parameter i.e.
BVEc2 = [VV_St / (PVRc2 + VV_St)] x 100.
