Cell therapy aims to fix stubborn bladder leaks after failed surgery
NCT ID NCT03104517
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new treatment called AMDC-USR (iltamiocel) for women who still have stress urinary incontinence after having surgery for it. The treatment uses the patient's own muscle cells injected into the urinary sphincter to strengthen it. Half of the 96 participants get the cell injection, half get a placebo, and researchers track how many leaking episodes they have.

Inclusion Criteria: * Adult female patient ≥ 18 years of age who has primary and moderate-to-severe symptoms of SUI for at least 6 months, as confirmed by patient medical history and clinical symptoms, including a focused incontinence evaluation. * History of previous surgery for treatment of SUI. Previous surgery could include midurethral sling, retropubic suspension, or bladder neck sling. Bulking agents alone are not considered previous surgery for treatment of SUI. * Must be willing and able to comply with the study procedures, be mentally competent and able to understand all study requirements, and must agree to read and sign the informed consent form prior to any study-related procedures. * Must have completed 100% of the screening 3-day diary evening reports. Exclusion Criteria: * Patient has symptoms of only urge incontinence as confirmed by basic evaluation of etiology from a patient medical history, including a focused incontinence history. * Patient has symptoms of mixed urinary incontinence where urge incontinence is the predominant factor. * Patient has had stress urinary incontinence symptoms less than 6 months prior to signing the informed consent. * Patient has not previously attempted conservative treatment prior to signing the informed consent. (Examples of conservative treatment include behavior modifications, bladder exercises, biofeedback, pelvic floor muscle therapy, etc.) * Patient BMI ≥ 35. * Patient routinely has more than 2 episodes of awakening to void during normal sleeping hours. * If taking a medication known to affect lower urinary tract function, including but not limited to, anticholinergics, beta 3 adrenergic receptor agonists, tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitor (SNRI) or selective serotonin reuptake inhibitor (SSRI) antidepressants, diuretics, or alpha-adrenergic blockers, patient cannot be maintained on a stable dose and/or frequency of medication (including diuretics), cannot be maintained on a stable dose and/or frequency for at least 2 weeks prior to screening or is likely to change during the course of the study. * History of cancer in pelvic organs, ureters, or kidneys. * Patient is pregnant, lactating, or plans to become pregnant during the course of the study.
