Brief Summary

The aim of the original study was to compare Incobot/A versus Onabot/A in order to evaluate if the differences in the pharmacologic formulations between the two drugs could affect their efficacy and safety in the treatment of neurogenic overactive bladder (OAB). In the original study protocol two different dosages for either Incobot/A and Onabot/A (200 U and 100 U) were considered, to treat patients with neurogenic detrusor overactivity incontinence performing intermittent catheterization (IC) with higher dosages and those able to void spontaneously with lower dosage, with the resulting four treatment groups. For such a study, a very large sample of participants should have been treated and followed up, to have adequate power to demonstrate the hypothesis. At the end of last February 2020, we had to temporarily stop all the clinical activities related to the study and patients' recruitment, due to the occurrence of Sars-Cov-2 pandemic in our Country. At that point, a non-inferiority study seemed to be possible and adequate, and we adapted the protocol accordingly. In addition, on the basis of previously published information, we could hypothesize that the new drug (Incobot/A) would have had at least a roughly similar effect to the control drug (Onabot/A). In order to perform a non-inferiority study, the power and sample size analysis have been re-planned. Thus, we perform a not planned interim analysis to show the preliminary results of an ongoing, non-inferiority trial in which patients' recruitment temporarily stopped due to incontrollable external factors. The present study will be aimed to assess the non-inferiority of Incobot/A compared to Onabot/A on the efficacy and safety parameters, in the treatment of patients with refractory NDOI performing IC, who are randomized to receive 200 U of Incobot/A or Onabot/A intradetrusor injections and who are followed up to 12 wks after treatment

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • patients (males and females) with neurogenic urge urinary incontinence (UUI) (with urgency, increase in day- time and night- time urinary frequency) and with urodynamic diagnosis of DO;
  • years;
  • women of childbearing age, who use a reliable method of contraception throughout the study period (a pregnancy test must be performed during enrolment in the study);
  • spinal cord injury at or below T1, diagnosed at least 6 months before the screening in case of a vesico-sphincter dysfunction due to spinal cord injury;
  • EDSS score ≤ 6, in MS patients;
  • patients refractory to anticholinergic therapy (≥ 1 anticholinergic agent)
  • application of intermittent catheterizations to empty the bladder. In the case of spontaneous micturition, the patients should agree for the use of intermittent catheterizations, in case this will be necessary after treatment with the detrusor injection of botulinumtoxin A.

You may not qualify if:

  • recurring urinary tract infections (UTIs) (≥ 4 episodes/year);
  • spinal cord injuries above T1;
  • MS patients: EDSS score ≥ 6;
  • patients who won't or can't perform intermittent catheterization;
  • pregnancy or breast- feeding, if female patients;
  • post- void residual volume (PRV) \> 150 ml, in the case of spontaneous micturition;
  • hypersensitivity to the active substance or to any of the excipients (listed in section 6.1 of RCP);
  • generalized diseases of muscular activity (e.g. myasthenia gravis, Lambert-Eaton syndrome);
  • presence of infection or inflammation at the injection site;
  • patients with acute urinary retention at the time of treatment, not routinely subjected to catheterization;
  • men with overactive bladder and signs or symptoms of urinary obstruction should not be treated;
  • documented or suspected active malignant neoplasia or previous history, within 2 years prior to screening;
  • patients who must or want to continue taking illegal drugs or drugs that may interfere with the proper conduct of the study;
  • chronic abuse of alcohol or drugs or any condition that in the opinion of the investigator doctor makes an unreliable subject in correctly completing the study procedures;
  • any other clinical condition that would endanger the safety of patients in participating in the study or that could prevent the subjects from adhering to the protocol.
