Study Summary

By hypothesising that Interstitial Cystitis is an allergic disorder of the urogenital system that is linked to mast-cells, current therapy with omalizumab may represent a potential non symptomatic strategy for the treatment of IC/BPS

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Female patients 18 years, with a range in body weight of 20 and 150 kg, who haveprovided written informed consent

  • In patients diagnosed with IC/PBS that underwent treatment, basal levels of totalserum IgE were 30 and 700 IU/ml and patients showed a positive allergic anamnesis (asthma, rhinitis, atopic dermatitis, etc.)

  • Diagnosis of IC/PBS was performed according to the criteria established by theNational Institute of Health Consensus Conference and patients had symptoms for atleast 3 months. Cytoscopy was performed according to the clinical indications

Exclusion

Exclusion Criteria:

  • Pregnancy, breastfeeding. Fertile women that did not use secure contraceptive methods (hormonal or double barrier method). Hysterectomized or surgically sterilized women (tubal ligation) and menopause women were admitted into the study.

Study Description

Interstitial cystitis/Bladder Pain Syndrome is a chronic inflammatory disease of the bladder, that is characterized by pain in the pelvic region and a frequent need to urinate. So far there is not a an effective treatment for this uncommon distressing condition.

The objective of this preliminary study was to evaluate the efficacy of omalizumab in the treatment of Interstitial Cystitis/Bladder Pain Syndrome, evaluated by visual analogue score (VAS) for pain and urgency- frequency, O'Leary-Sant IC symptom and problem index questionnaire (primary outcome), PUF questionnaire and Patient Global Assessment questionnaire, and urination diary (secondary outcomes).

Three female adult patients (24-34 years) suffering form Interstitial Cystitis and chronic bladder pain were included in the study. The omalizumab dose has been calculated on the basis of body weight and basal levels of total serum IgE. Treatment was administered subcutaneously every 2 or 4 weeks (according to the calculated total dose) for a total of 48 weeks. Each vial contained 150 mg of the active compound, therefore the number of injections for each administration varied between 1 and 3, depending on the total dose used. Patients were allowed to take drugs used for IC (Fibrase, Pelvilen, Normast, Quercetin, Chondroitin, Glucosamine per os). During the screening process, the dosage of these drugs was established and stably maintained during the 4 week run-in period.
