· Data presented at EAU 2026 show an 89 percent complete response rate in intermediate‑risk disease with durable responses observed over 18 months and tolerable safety profile
· Erda-iDRS has the potential to be the first targeted treatment for early‑stage bladder cancer
RARITAN, N.J., March 13, 2026 – Johnson & Johnson (NYSE:JNJ) today announced results from an open-label, multicenter Phase 1 study evaluating an investigational intravesical drug-releasing system with erdafitinib (Erda-iDRS) in patients with intermediate-risk and high-risk non–muscle-invasive bladder cancer (NMIBC) whose tumors harbor select fibroblast growth factor receptor (FGFR) alterations. The study met its primary safety endpoint and demonstrated complete and durable responses in patients with recurrent intermediate-risk disease, along with encouraging recurrence-free outcomes in high-risk disease. These findings support continued development of this targeted approach with ongoing Phase 2 and Phase 3 studies evaluating Erda-iDRS across risk settings. Data were presented during a late-breaking oral session at the European Association of Urology (EAU) 2026 Annual Meeting (Abstract #LB26-0083).1
FGFR alterations are common in early-stage bladder cancer, occurring in approximately 70 percent of intermediate-risk and 40 percent of high-risk non–muscle-invasive bladder cancer tumors.2,3 Because these changes may drive tumor growth, they represent an important therapeutic target in this setting. Erda-iDRS is designed to provide prolonged release of erdafitinib, an oral kinase inhibitor, directly into the bladder via intravesical administration over a three-month period, and may enable localized treatment while aiming to minimize systemic exposure and the risk of adverse events associated with oral administration.
“Intermediate-risk non–muscle-invasive bladder cancer is defined by recurrences, and many patients undergo repeated procedures as their tumors return,” said Antoni Vilaseca Cabo,* M.D., adjunct physician of the Urology Service at Hospital Clínic de Barcelona in Spain, and presenting author. “In this study, treatment with Erda-iDRS led most patients with FGFR-altered disease to achieve a complete response by the end of the second treatment cycle, and many of those responses were sustained over time. Achieving and maintaining a complete response is particularly meaningful in this setting, where recurrence is common and requires repeated surgical intervention.”
“For patients with FGFR-altered non–muscle-invasive bladder cancer, care has historically not been guided by precision‑based approaches,” said Christopher Cutie, M.D., Vice President, Disease Area Leader, Bladder Cancer, Johnson & Johnson. “The high and durable complete responses demonstrated with Erda-iDRS highlight the opportunity to deliver a targeted therapy to these patients. Bringing a biology-based approach into earlier stages of this disease has the potential to change how these patients are treated.”
About Erdafitinib Intravesical Drug-Releasing System (Erda-iDRS)
Erda-iDRS is an investigational intravesical drug delivery system designed to deliver prolonged, localized erdafitinib, an oral kinase inhibitor, directly to the bladder. The safety and efficacy of Erda-iDRS are being evaluated in a Phase 1 study in patients with non–muscle-invasive bladder cancer (NMIBC), including those with high-risk, BCG-unresponsive disease and intermediate-risk disease with visible tumors. Additional Phase 2 and Phase 3 studies are ongoing to further assess Erda-iDRS across intermediate- and high-risk NMIBC.
In 2008, Janssen Pharmaceuticals entered into an exclusive worldwide license and collaboration agreement with Astex Pharmaceuticals to develop and commercialize erdafitinib.
About Non–Muscle-Invasive Bladder Cancer
Non–muscle-invasive bladder cancer (NMIBC) is an early stage of bladder cancer confined to the lining of the bladder. It accounts for approximately 75 percent of newly diagnosed bladder cancer cases. NMIBC is categorized as low-, intermediate-, or high-risk based on tumor characteristics and likelihood of recurrence or progression.7
Patients with intermediate-risk NMIBC experience frequent tumor recurrences that often require repeated procedures and ongoing monitoring. High-risk NMIBC carries a greater likelihood of progression to muscle-invasive disease, which may require radical cystectomy.8,9,10 Despite available treatments, recurrence and progression remain common across intermediate- and high-risk disease, underscoring the need for durable bladder treatment options.
