简要总结
The purpose of this research study is to identify the optimal usage of Onabotulinumtoxin A in interstitial cystitis. Onabotulinumtoxin A, more commonly known by the trade name Botox®, is a medication that comes from the bacteria Clostridium botulinum. It works by blocking the release of the neurotransmitter acetylcholine(a chemical messenger that carries signals between nerve cells and other cells in the body). Blocking that neurotransmitter results in decreased muscle activity.
详细描述
The purpose of this study is to evaluate the efficacy of intravesicular Onabotulinumtoxin A injections for the treatment of interstitial cystitis (IC). Specifically, we hypothesize that trigonal Onabotulinumtoxin A injections is an effective treatment for IC and will result in more subjective and objective symptom relief than posterior wall Onabotulinumtoxin A injections.

入选标准
- •Adult females between the ages of 18 and 80 inclusive
- •Patients being treated for IC who are refractory to conservative management and oral therapy.
- •willing and able to initiate catheterization post-treatment
排除标准
- •Any history of bladder cancer, uterine cancer, ovarian cancer, vaginal cancer, urethral diverticulum, spinal cord injury, stroke, Parkinson's disease, multiple sclerosis, spina bifida, cyclophosphamide treatment, radiation treatment to the pelvis, bladder tuberculosis, genital herpes.
- •Currently on or requiring anti-platelet/anti-coagulant concomitant therapy or having been on anti-platelet/ anti-coagulant therapy within the past 3 months
- •Pregnancy. Pregnancy is an absolute contraindication to undergoing these procedures. Thus, as part of their normal pre-operative work up, which is standard of care, pregnancy tests are administered if they are women of child-bearing age, are sexually active, and are within 10 days of the normal menstrual period. If positive, they will be excluded as they will not undergo the procedure.
- •An active urinary tract infection as shown during clean-catch urinalysis at screening visit. Subject may be re-screened if UTI is successfully treated and urinalysis is negative at rescreening.
- •A history of hypersensitivity or allergy to any botulinum toxin preparation
- •A post-void residual (PVR) urine volume >200mL at baseline
- •Treatment with botulinum toxin during the 12 week period prior to the trial
研究组 & 干预措施
Botox upper aspect trigone
Subjects in the experimental cohort will receive a one time dose of 100 units of Onabotulinumtoxin A diluted in 10 mL of preservative free normal saline and injected in 1.0 mL boluses in a set pattern across the upper aspect of the trigone of the urinary bladder.
干预措施: Onabotulinumtoxin A (Drug)
Botox upper aspect trigone
Subjects in the experimental cohort will receive a one time dose of 100 units of Onabotulinumtoxin A diluted in 10 mL of preservative free normal saline and injected in 1.0 mL boluses in a set pattern across the upper aspect of the trigone of the urinary bladder.
干预措施: injections upper aspect of trigone of urinary bladder (Procedure)
botox periphery of trigone
Each group will receive a total of 100 units of botox spread out among 10 separate injections. Subjects in the control group will have 10 injections made about the periphery of the trigone. The control cohort will receive a one time dose of Onabotulinumtoxin A using the same dilution and number of boluses, but boluses will be administered at random sites on the posterior bladder wall (excluding the trigone).

结局指标
主要结局
The Primary Outcome Will be Assessing the Measurement of Subjective Patient Pain Using the O'Leary-Sant Symptom and Problem Indexes.
时间窗: 30 and 90 days post treatment
The O'Leary-Sant is one questionnaire that assesses the severity of symptoms and the how much of a problem the symptoms cause for the patient and it provides two scores. The scores ranges for the symptoms is 0-20 and for how bothersome the symptoms are, the score range is 0-16. Higher scores for both denotes worse outcomes.
The Primary Outcome Will be Assessing the Measurement of Subjective Patient Pain Using the Pelvic Pain and Urinary Urgency Frequency (PUF) Questionnaire
时间窗: 30 and 90 days post-treatment
The PUF questionnaire evaluates symptoms of pain and how much they bother the patient. Two score are given and added together to produce a total score. The score range for symptoms is 0-28 and the range for bother is 0-16. Higher scores denotes worse outcomes.
次要结局
- Change in Patient Performance in Uroflowmetry.(30 days and 90 days post treatment)
