The efficacy and safety of monoclonal antibody therapies for interstitial cystitis/bladder pain syndrome: A meta‐analysis of randomized controlled trials

Objectives This study aimed to assess the efficacy and safety of monoclonal antibody therapies (MATs) for interstitial cystitis/bladder pain syndrome (IC/BPS). Methods A systematic search was conducted across databases including PubMed, Embase, clinicalTrial.gov, and the Cochrane Library Central Register of Controlled Trials. Randomized controlled trials (RCTs) comparing MATs versus placebo were included. Primary outcomes comprised the Global Response Assessment (GRA) scale and the O'Leary‐Sant Interstitial Cystitis Symptom Index (ICSI). Additional analyses encompassed mean daily frequency of voids, the O'Leary‐Sant Interstitial Cystitis Problem Index, pain scores, and complications. Statistical analyses were performed using Review Manager 5.3. Results Five high‐quality RCTs, comprising 263 patients with IC/BPS, were ultimately selected. MATs were generally effective in treating IC/BPS. Patients receiving MATs exhibited a higher satisfaction rate (odds ratio [OR]: 2.7, confidence interval [CI]: 1.31–5.58, p = 0.007) and lower ICSI scores (mean difference [MD]: −1.44, CI: −2.36 to −0.52, p = 0.002). Moreover, MAT recipients experienced reduced pain (MD: −0.53, CI: −0.79 to −0.26, p
