Detaljeret beskrivelse

Subject that meet inclusion and exclusion criteria will be consented and enrolled in this study. Initial screening includes blood and urine testing, questionnaires, physical examination, specialized bladder function testing and review of medical history. At the next visit a small sample of each subject's own thigh muscle is obtained by needle biopsy. This cell biopsy is sent to a specialized lab for growth and processing. Approximately ten weeks later the frozen cells will be sent back to the treatment site for thawing, diluting and injection under lighted instrumentation into the subject's bladder wall. The subject will be followed for 6 months and at that time may be eligible for a second injection of cells. The study doctor will determine if the second injection may be beneficial to the subject. All subjects will be followed for up to 12 months. The follow-up assessments at 12 months will include questionnaires, urine and blood testing, specialized bladder function testing and visualizing the inside of the bladder with a lighted instrument.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Autologous Muscle Derived Cells
Autologous Muscle Derived Cells are obtained by needle biopsy from the subject's own thigh muscle. These cells are sent to a special lab for growth and processing. When ready the cells are sent to the treatment location for injection into the bladder wall.
Biologisk: Autologous Muscle Derived Cells
A small sample of the subject's own thigh muscle is obtained by needle biopsy. The biopsy sample is sent to Cook Myosite, Inc. for growth and processing. When the sample cell dosage is achieved the cells are frozen and sent back to the treatment site. The cells are thawed, diluted and injected under lighted instrumentation and visualization into about 30 sites in the bladder wall.

Long term safety of Autologous Muscle Derived Cells in the treatment of underactive bladder as measured by occurrences of study-related adverse events (AEs) reported between 6 and 12 months after enrollment. Number of reports of each adverse event is listed for events determined to be definitely or possibly related to study activities.

Number of Participants With Improvement in Underactive Bladder Symptoms at 12 Months.
Tidsramme: 12 months
The efficacy of Autologous Muscle Derived Cells in the treatment of underactive bladder as measured by changes to subject completed GRA questionnaire. The GRA measures the subjects perceived level of change in underactive bladder symptoms at 12 months compared to before they were treated. The scale ranges from: Markedly worse, Moderately worse, Slightly worse, No change, Slightly improved, Moderately improved, to Markedly improved. Subjects select one response.
12 months
Number of Participants With Improvement in Underactive Bladder Symptoms at 12 Months.
Tidsramme: 12 months
The efficacy of Autologous Muscle Derived Cells in the treatment of underactive bladder as measured by changes to subject reported degree of change in urinary symptoms on the PGI-I at 12 months, compared to how their symptoms were before they began the study. Subjects select one response. The response scale ranges from: Very much better, Much better, A little bit better, No change, A little worse, Much worse, Very Much worse.

Change in Incontinence Questionnaire (ICIQ) Long Form Score From Baseline at 12 Months.
Tidsramme: 12 months
The efficacy of Autologous Muscle Derived Cells in the treatment of underactive bladder as measured by changes to subject reported urinary symptoms at 12 months from baseline. The ICIQ has a separate female (ICIQ-FLUTS Long form) and male (ICIQ-MLUTS long Form) set of questions to assess urinary symptoms in each sex. The total score range for ICIQ-FLUTS is 0-69. The total score range for ICIQ-MLUTS is 0-84. The sum of all the question scores equal a total score. Each question has a degree of bother scale associated with it. The degree of bother ranges from 0 (none at all) to 10 ( a great deal). Degree of bother scores are not incorporated in the overall score but indicate impact of the individual symptom. The difference taken in this analysis is the difference between the total score at 12 months minus the total score at baseline. If the difference is negative, it indicates improvement in the symptoms; 0 is no change; and a positive difference indicates a worsening of the symptoms.
12 months
Change in Underactive Bladder Questionnaire (UABQ) Score From Baseline at 12 Months
Tidsramme: 12 months
The efficacy of Autologous Muscle Derived Cells in the treatment of underactive bladder as measured by subject reported changes to urinary symptoms at 12 months from baseline on the UABQ. The UABQ is a set of questions to assess urinary symptoms associated with underactive bladder. The total score ranges between 0 to 16. A lower score indicates a better outcome. A higher score indicates a worse outcome.
