Pilot Study Evaluating the Efficacy of Certolizumab Pegol for Interstitial Cystitis

Study Overview
=================
Brief Summary
-----------------
A Randomized, Double-blind, Placebo Controlled Trial of Certolizumab Pegol in Women with Refractory Interstitial Cystitis/Bladder Pain Syndrome

Detailed Description
-----------------
Interstitial cystitis (IC) is a chronic disabling bladder syndrome characterized by urinary frequency, nocturia, urinary urgency, and pain or discomfort with bladder filling. There is no cure for IC and the treatment options are suboptimal. Patients with IC report significant negative effects on their physical and mental quality of life. The etiology of IC is unknown. Certain aspects of IC suggest that autoimmunity may play a role in initiating or sustaining the chronic inflammatory response. Bladder biopsies of patients with IC demonstrate an increase number of mast cells. Mast cell activation with the release of tumor necrosis factor (TNF) may mediate this bladder inflammation. Cimzia (certolizumab pegol) is a medication that blocks the effect of TNF. Cimzia (certolizumab pegol) is FDA approved for the treatment of rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and Crohn's disease. These diseases are similar to IC. In this study, the hypothesis being tested is that Cimzia (certolizumab pegol) will show efficacy in improving the symptoms of patients with IC.

O'Leary-Sant Interstitial Cystitis Symptom and Problem Indexes (OSPI) score ≥ 18 No history of any cancer. No bacterial cystitis in previous 1 month No active herpes in previous 3 months Never treated with cyclophosphamide No neurogenic bladder dysfunction (due to a spinal cord injury, stroke, Parkinson's disease, multiple sclerosis, spina bifida or diabetic cystopathy) Absence of bladder, ureteral or urethral calculi for previous 3 months Exclusion criteria: Symptoms are relieved at one month reevaluation visit after receiving IC/BPS behavior modification advice at screening visit. Symptoms are relieved by antimicrobials, antibiotics, or other medications for IC/BPS Pregnant women, lactating mothers, nursing mothers, women suspected of being pregnant and woman who plan to be pregnant during the course of the clinical trial Males Patients with inadequate renal, hepatic, or cardiac function Patients with history of gross hematuria within 2 years. Patients with the following medical history: Lower urinary tract anatomical anomaly, pelvic radiotherapy, or active genital herpes Patients with a history of tuberculosis (TB), recent exposure to TB, or recent travel to TB endemic regions. Patients should have a recent negative PPD (or negative CXR) prior to receiving treatment. Patients who have undergone cystoscopy under anesthesia with bladder biopsy, hydrodistension, or fulguration of Hunner's ulcer within 3 months Patients taking the following treatments for interstitial cystitis at Screening: Intravesical BCG, corticosteroid therapy, cyclosporine, or TNF-alpha inhibitors. Patients with a history of receiving live vaccine including Flumist® influenza vaccine in the past 3 months. Patients with a history of allergic or anaphylactic reaction to a therapeutic or diagnostic monoclonal antibody or IgG-fusion protein. Patients with a history of alcohol, analgesic or drug abuse within 2 years of Screening. Patients with a history of any cancer. Patients with a history of active Hepatitis B, Hepatitis C, or Human Immunodeficiency Virus (HIV) infection, or who are known carriers (Hepatitis B). Patients with a history of invasive fungal infections, recent travel to regions endemic for the following invasive fungal infections: San Joaquin Fever, aspergillosis, histoplasmosis, candidiasis, coccidiodomycosis, blastomycosis, and pneumocystosis. Patients with a history of diabetes mellitus. Patients with a history of a neurologic disease included but not limited to central demyelinating diseases, including multiple sclerosis; and a history of peripheral demyelinating disease, including Guillain-Barre syndrome. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient inappropriate for entry into this study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| IC/BPS Symptoms Change With Overall Global Response Assessment (GRA) | Patient-reported global response assessment (GRA) such as Compared to when you began this trial, how would you rate your IC symptoms now? Study subjects reported their response to treatment of their pain, urgency, and overall status compared to their condition at trial start with a symmetric scale global response assessment (GRA) 28 at weeks 2, 4, 10, and 18. Possible responses were markedly worse (100% worse), moderately worse (50% worse), slightly worse (25% worse), no change (0% improvement), slightly improved (25% improvement), moderately improved (50% improvement), and markedly improved (100% improved). Treatment responders were defined by rating the GRA as moderately improved or markedly improved. | Week 2 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| IC/BPS Symptoms Change With Overall Global Response Assessment (GRA) | Patient-reported global response assessment (GRA) such as Compared to when you began this trial, how would you rate your IC symptoms now? Study subjects reported their response to treatment of their pain, urgency, and overall status compared to their condition at trial start with a symmetric scale global response assessment (GRA) 28 at weeks 2, 4, 10, and 18. Possible responses were markedly worse (100% worse), moderately worse (50% worse), slightly worse (25% worse), no change (0% improvement), slightly improved (25% improvement), moderately improved (50% improvement), and markedly improved (100% improved). Treatment responders were defined by rating the GRA as moderately improved or markedly improved. | Week 4, 10, 18 | 
| IC/BPS Symptoms Assessment With the Interstitial Cystitis Symptom Index | The Interstitial Cystitis Symptom Index is one of the two O'Leary-Sant Interstitial Cystitis Symptom and Problem Indexes. This scale has a 0 if the patient has no symptoms and a maximum of 19 with severe symptoms. Lubeck et al. validated ICSI as a valid measure of change in treatment outcome studies. A change of -4.03 in the ICSI score was the same as a 2 point improvement in GRA. Propert et al. validated the ICSI as responsive to change in IC/BPS symptoms and was recommended as secondary endpoints in clinical trials. A change of -2.4 in the ICSI score was the same as a 2 point improvement in GRA. | Value at Weeks 2, 4, 10 and 18 minus Baseline | 
| IC/BPS Symptoms Assessment With the Interstitial Cystitis Problem Index (ICPI) | The Interstitial Cystitis Symptom Index (ICPI) is one of the two O'Leary-Sant Interstitial Cystitis Symptom and Problem Indexes. This scale has a 0 if the patient has no symptoms and a maximum of 16 with severe symptoms. | Value of Weeks 2, 4, 10, and 18 minus baseline | 
| Pain Scale | an 11-point pain intensity numerical rating scale. Subjects rated their average pain, pressure, or discomfort associated with their bladder using an 11-point pain intensity numerical rating scale of 0-no pain to 10-worse ever pain at baseline, and at weeks 2, 4, 10, and 18. Meaningful, clinically important pain relief is a reduction in pain of approximately 30% from baseline. | Value at Weeks 2, 4, 10, and 18 minus baseline | 
| Urgency Scale | Subjects rated their average urinary urgency or need to urinate using an 11-point numerical rating scale of 0-no urgency to 10-worse ever urgency | Value of Weeks 2, 4, 10, and 18 minus baseline |
