Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to determine the effectiveness and safety of mirabegron compared to oxybutynin chloride immediate release (oxybutynin IR) for a condition called neurogenic detrusor overactivity in individuals with chronic spinal cord injury (SCI).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Neurogenic detrusor overactivity or "NDO" is common in people with spinal cord injury (SCI) and is a medical condition characterized by involuntary urinary bladder contractions. These bladder contractions can cause episodes of urinary incontinence (involuntary urine leakage) and/or high bladder pressures that can lead to poor drainage from the kidneys and urinary tract infections (UTIs).

Neurogenic detrusor overactivity is most commonly treated with a medication called oxybutynin (Ditropan); however, this medication is associated with side effects such as dry mouth and constipation. Mirabegron (Myrbetriq) is a newer medication approved by the Food and Drug Administration for the treatment of overactive bladder that does not cause dry mouth or constipation; however, its use in persons with SCI is investigational.

The purpose of this research study is to determine the effectiveness and safety of mirabegron compared to oxybutynin chloride immediate release (oxybutynin IR) for neurogenic detrusor overactivity in individuals with SCI.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

After a two-day washout period, participants will be randomly assigned to one of two treatment groups: 1) an escalating dose of mirabegron for 6 weeks (25 mg once daily plus two placebo pills for 2 weeks, followed by 50 mg once daily plus 2 placebo pills for 4 weeks); or 2) Oxybutynin IR (5 mg orally three times daily) for 6 weeks. All participants will then be switched to the opposite study treatment for 6 weeks. Assessments will be performed at Baseline, Week 6 (completion of first study medication and prior to administration of second study medication), and Week 12 (completion of second study medication).

Participants Caregivers Investigators Outcome Assessors
All study investigators, participants, and assessors will be blind to group assignment. Blinding code will only be broken in emergency situations for reasons of subject safety, where knowledge of the treatment administered is necessary for the treatment of the adverse event under Good Clinical Practices (GCPs), or when required by local regulatory authorities.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Oxybutynin chloride IR then Mirabegron

Subjects randomized to this group will receive oxybutynin IR (5 mg three times daily) for 6 weeks. After the initial 6 weeks, subjects in this group will then be switched to an escalating dose of mirabegron for 6 weeks (25 mg once daily for 2 weeks, followed by 50 mg once daily for 4 weeks; Note: two placebo daily will be included with mirabegron once daily to match the frequency of dosing to oxybutynin IR three times daily).

Group Type EXPERIMENTAL

Oxybutynin Chloride IR

Intervention Type DRUG

Oxybutynin chloride immediate release (IR) 5 mg three times daily for 6 weeks

Mirabegron

Intervention Type DRUG

Mirabegron 25 mg tablet once daily for 2 weeks, followed by mirabegron 50 mg once daily for 4 weeks (Note: Placebo twice daily will be included with mirabegron once daily to match the three-time daily dosing of oxybutynin IR in the other intervention).

Mirabegron then Oxybutynin chloride IR

Subjects randomized to this group will receive an escalating dose of mirabegron for 6 weeks (25 mg once daily for 2 weeks, followed by 50 mg once daily for 4 weeks; Note: two placebo daily will be included with mirabegron once daily to match the frequency of dosing to oxybutynin IR three times daily). After the initial 6 weeks, subjects in this group will then be switched to receive oxybutynin IR (5 mg three times daily) for 6 weeks

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* The subject has a neurological impairment secondary to a traumatic spinal cord injury that occurred at least twelve (12) months prior to the screening visit.
* The injury is classified as complete or incomplete (AIS grade A-D) and the neurological level of the injury is above T12.
* The subject's method of bladder management is intermittent catheterization (IC) or indwelling catheter (transurethral or suprapubic).
* There is urodynamic documentation of neurogenic detrusor overactivity (NDO).
* The subject is on a stable dose of oxybutynin IR three times daily.
* The subject is able and willing to comply with the study protocol, including availability for all scheduled clinic visits and locomotor training sessions.
* The subject is able to and has voluntarily given informed consent prior to the performance of any study-specific procedures.

Exclusion Criteria

* The subject has taken mirabegron within one month of the Screening Visit.
* The subject has received a botulinum toxin injection to the bladder within one year of the Screening Visit.
* The subject is allergic to mirabegron.
* The subject has a history of uncontrolled autonomic dysreflexia or significant autonomic dysreflexia on urodynamics (systolic BP≥150 mm/Hg).
* The subject has a known history of significant anatomical problems of the upper tracts, including hydronephrosis, kidney stones, or ureteropelvic junction obstruction.
* The subject has a known history or treatment for a non-neurogenic bladder or prostate problem (prostate cancer, bladder cancer).
* The subject has recurrent UTIs, defined as a UTI more than every three months.
* The subject has untreated Grade 3 or above vesicoureteral reflux.
* If female, the subject is pregnant (documented by a urine pregnancy test) or breastfeeding.
* The subject has taken another investigational drug within 30 days before screening.
* The subject has a medical condition that might pose a safety issue or would interfere with interpretation of study results or study conduct.
