Brief Summary:
The aim of the SUISSE MPC 2 study is to treat stress urinary incontinence in adult women.

Condition or disease Intervention/treatment Phase
Female Stress Urinary Incontinence Biological: autologous muscle precursor cells Phase 2

Detailed Description:

Stress urinary incontinence is the loss of small amounts of urine associated with coughing, laughing, sneezing, exercising or other movements that increase pressure on the abdomen and therefore increasing the pressure on the bladder.

The goal of the SUISSE MPC2 study is to treat SUI in women using their own autologous muscle precursor cells. To guarantee enough outcome data a sufficient number of patients will be enrolled to complete the study with 70 patients.

The study will last approximately 8-9 months per patient. Each patients baseline measurements serve as comparison for the treated measurements.

Patients will participate in the study for up to approximately 8 to 9 months, including a baseline visit for screening, a visit to obtaing a muscle biopsy up to 8 weeks later, an injection of MPCs up to 5 weeks later, and follow-up visits after 1, 3 and 6 months post injection.

All patients will be treated with one of the two doses of MPCs, assigned according to the study's randomization method.

Half of the participating patients will receive the cell therapy that was previously studied in the completed phase I study. The other half of the participants, will receive a higher dose of the cell therapy to investigate the effects of dose increase. Both groups of patients will be additionally monitored by medical examinations performed by clinicians to ensure the safety of the treatment.

Furthermore, separate to the Principal Investigator, safety events will be reported to and investigated by the independend Data Safety Monitoring Board consisting of independent physicians and experts in the field. The injection is performed with ultrasound guidence using an endocavity ultrasound probe.

Arm Intervention/treatment
Experimental: Low dose
Already human tested low dose from phase I study
Biological: autologous muscle precursor cells
Patients own Muscle Precursor Cells are isolated and injected into the rhabdomyosphincter

Experimental: High dose
First in human dose used for efficacy reasons during phase II
Biological: autologous muscle precursor cells
Patients own Muscle Precursor Cells are isolated and injected into the rhabdomyosphincter

Primary Outcome Measures :
  1. Change of SUI episode frequency [ Time Frame: 8-9 months ]
    Assesment in episode change measured using a bladder diary, from baseline to 6 months after injection.

Secondary Outcome Measures :
  1. Incidence of (S)AEs [ Time Frame: 6-8 months ]

    AEs related to obtaining biopsy , injection procedure and MPCs, including surgical injury, scars, urinary tract infection, inflammation, pelvic pain, prolonged urinary retention, voiding dysfunction, de novo urge incontinence, haematuria, aberrant tissue formation.

    Measured from Visit 2 (biopsy) to End of Study.

  2. Number of patients with any clinical significant findings [ Time Frame: 8-9 months ]
    Number of patients with any clinically significant findings based on physical examination, standard haematology, clinical chemistry and urinalysis profiles, blood pressure (BP), pulse and adverse events recordings at baseline, 1 month, 3 months and 6 months post-implantation.

  3. Change in pad weight [ Time Frame: 8-9 months ]
    Change in pad weight based on using regular pad tests, from baseline to 6 months after injection.

Other Outcome Measures:
  1. Change in total leakage episodes [ Time Frame: 8-9 months ]
    Response rate at 6 months, defined as percentage of patients with at least 50% change in number of stress leaks

  2. Questionnaire ICIQ-UI SF (International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form ) [ Time Frame: 8-9 months ]
    Change in score from baseline to 6 months. Containing 1 scale ranging from 0 (not at all) to 10 (serious) measuring the impairment caused by urine leakage in everyday life.

  3. Questionnaire ICIQLUTSqol (International Consultation on Incontinence Questionnaire Lower Urinary Tract Symptoms quality of Life) [ Time Frame: 8-9 months ]
    Change in score from baseline to 6 months. This questionnaire contains 21 questions to measure the impact of urinary incontinence on quality of life with particular reference to social effects. Each question is accompanied by a scale to capture the subjective restriction concerning the respective topic. These scales range from 0 (not at all) to 10 (very much).

  4. Questionnaire VAS (Visual analogue scale) [ Time Frame: 8-9 months ]
    Change score for degree of suffering, quality of life overall and subjective health status from baseline to 6 months. Scales ranging from 0 to 10. For Quality of life and health status from 0 "very bad" to 10 "very well". The degree of suffering from 0 (low) to 10 (high).

  5. Urethral pressure profile [ Time Frame: 8-9 months ]
    It measures the changes in the bladder pressure (in cm/H2O) required to urinate and the flow rate (in ml/s) a given pressure generates between baseline and 6 months after injection.

  6. Urodynamic cystometric test [ Time Frame: 8-9 months ]
    It measures the change of how much urine (in mL) the bladder can hold, between baseline and 6 months after injection.

  7. Urodynamic cystometric test [ Time Frame: 8-9 months ]
    It measures the change how much pressure builds up inside the bladder (in cm/H2O) as it stores urine, between baseline and 6 months after injection.

  8. Urodynamic cystometric test [ Time Frame: 8-9 months ]
    It measures the change how full the bladder is (in mL) when the urge to urinate occurs, between baseline and 6 months after injection.

  9. Urodynamic leak point pressure measurement [ Time Frame: 8-9 months ]
    It measures the changes of pressure (in cm/H2O) at the point of leakage between baseline and 6 months after injection.

  10. % of subjects with successful injection [ Time Frame: 1 day ]
    at day of implantation
