neurogenic detrusor overactivity due to spinal cord injury |
|
E.1.1.1 | Medical condition in easily understood language |
The neurogenic detrusor overactivity is a disease and event affecting the nervous systems controlling the lower urinary tract, that leads to urinary incontinence and poor quality of life. |

|
E.2.2 | Secondary objectives of the trial |
Secondary objectives of the study are to study pharmacokinetics and pharmacodynamics parameters. |

E.3 | Principal inclusion criteria |
1. Male and female subjects aged ≥18 years and ≤65 years. 2. Female subjects must be either sterile or, if with child–bearing potential, must have a pregnancy test negative and commit to the use of a highly effective method of birth control (see Appendix 15.6) for the duration of the study, and until at least 1 month after the last dose of study medication. Male subjects must be willing to use male contraception (condom) to avoid pregnancies of their female partner of childbearing potential throughout the entire duration of the study, and for 3 months after the last dose of study medication. 3. Suffering from NDO due to SCI at upper motor neuron level (below C6) and emptying the bladder performing clear intermittent self-catheterization (CISC). 4. Subjects classified in group A, B, or C, of the ASIA (American Spinal Injury Association) impairment scale. 5. Stable therapy for NDO in the last thirty days (Subjects should maintain the therapy stable for the duration of the study). 6. At least 1 incontinence episode/day despite current treatment, according to what is reported in the Bladder Diary filled in by the subject. 7. Subjects with diastolic blood pressure values between 60 and 99 mmHg (both inclusive), and systolic blood pressure values between 90 and 159 mmHg (both inclusive). Blood pressure measurement must be performed in subjects with an empty bladder. 8. Subjects with stable concomitant medication treatment at baseline. 9. Written informed consent must be given by subjects before any study related investigational procedures is performed. |
|
E.4 | Principal exclusion criteria |
1. Breastfeeding women. 2. Treatment with injection of botulinum toxin, unless in the opinion of the Investigator the bladder activity has returned to pre-treatment level. 3. Use of prohibited concomitant medications, such as drugs that could affect immunoassay testing (systemic corticosteroids: prednisone, budesonide, prednisolone; calcineurin inhibitors: cyclosporine, tacrolimus; mTOR inhibitors: sirolimus, everolimus; IMDH inhibitors: azathioprine, leflunomide, mycophenolate; biologics: abatacept, adalimumab, anakinra , certolizumab, etanercept, golimumab, infliximab, ixekizumab, natalizumab, rituximab, secukinumab, tocilizumab, ustekinumab, vedolizumab; monoclonal antibodies: basiliximab, daclizumab, muromonab) or initiation of therapy with drugs affecting lower urinary tract symptoms (such as alpha-blockers, tadalafil 5 mg oad). If already present at Screening visit, therapy with drugs affecting lower urinary tract symptoms must be maintained stable through the study period (Note: occasional treatment with PDE-5 inhibitors for erectile dysfunction should be avoided between Screening visit and Day 8 and between Day 25 and 28). 4. History of cerebro- or cardio-vascular diseases (TIA, stroke, hypertensive encephalopathy, angina pectoris, MI, cardiac by-pass, CHF NYHA classes III and IV). 5. Uncontrolled type 1 or type 2 diabetes (Hb A1c >8 %). 6. Moderate to severe renal impairment (estimated creatinine clearance <60 mL/min by the Cockcroft-Gault equation). 7. Moderate to severe liver impairment (any liver function test: AST, ALT, GGT, Bilirubin >2.5 times the upper limit of normal). 8. Hemodynamically significant valve disease, including aortic stenosis or clinically significant ventricular or supraventricular arrhythmia, heart rate >100 beats/min. 9. Clinically important abnormal laboratory findings during the run-in period, including: Haemoglobin <10 g/dL; Serum Potassium >5.5 mmol/L; Serum Sodium <132 mmol/L. 10. Symptomatic active urinary tract infection (i.e. cloudy and/or malodorous urine, chills, fever, increased muscle spasticity or increased autonomic dysreflexia, letargy, hypotension, malaise). 11. Evidence of any neoplastic disease. 12. History of allergy, hypersensitivity or intolerance to drugs. 13. Participation in an investigational drug study within 30 days prior to the screening assessment. 14. Any other diseases or conditions, that according to the Investigator’s opinion, make the subject unable to comply with protocol requirements, or unable to complete the study or increases the risk to the subject or which prevents optimal participation in achieving the objectives of the study.

E.5 End points |
E.5.1 | Primary end point(s) |
SAFETY endpoints, which will be evaluated on an ongoing basis are: • Clinically relevant findings in post-dose physical examination, vital signs and ECG. • Clinically relevant changes in post-dose laboratory tests. • Adverse events. • Immunogenicity to Rec 0/0438.

SAFETY: on an ongoing basis

|
E.5.2 | Secondary end point(s) |
PHARMACOKINETICS endpoint: The systemic exposure after single (Day 1) and repeated (Day 7) once daily intravesical instillations of Rec 0/0438 (Cmax, AUC) will be evaluated: •A blood sample will be collected at screening and Three blood samples (6 mL each) will be collected on the day of first administration and on the 7th day of administration between 0.5-1 hour, between 2-3 hours and between 4-6 hours post dose, in order to determine if systemic exposure occurs. •Urine collection will be performed on Screening visit, and at the first and second voiding after drug administration on Day 1 and Day 7. PHARMACODYNAMIC endpoint: Urodynamic parameters (day -1 and day 28±4): •Change from baseline in Maximum Cystometric Capacity (MCC – main pharmacodynamic parameter) •Change from baseline in Maximum Detrusor Pressure (Pdetmax) •Change from baseline in Volume at first involuntary detrusor contraction (VpmaxIDC) •Change from baseline in Bladder Compliance (BC) •Change from baseline in Detrusor Leak Point Pressure (DLPP). Bladder Diary parameters (for 3 days before baseline, day 7 and day 28): •Change from baseline in the number of daily urinary incontinence (UI) episodes. •Change from baseline in mean volume per catheterization (total volume voided in 24 hours divided by the number of catheterizations).
