Johnson & Johnson (J&J, NYSE: JNJ) announced positive Phase I results for Erda-iDRS, an investigational intravesical drug-releasing system delivering erdafitinib directly to the bladder for non-muscle-invasive bladder cancer (NMIBC) with FGFR alterations. The open-label, multicenter study demonstrated 89% complete response (CR) in intermediate-risk patients with 18-month median duration of response, and 20-month median recurrence-free survival in high-risk patients with 83% 12-month RFS. The localized three-month sustained release approach aims to minimize systemic exposure while maintaining efficacy, supporting ongoing Phase II/III development across risk settings.
