FDA Approves J&J’s New Bladder Cancer Therapy
FDA has approved a Johnson & Johnson NDA for Inlexzo (gemcitabine intravesical system), offering a new treatment option for adults with non-muscle invasive bladder cancer (NMIBC) who do not respond to standard Bacillus Calmette-Guérin (BCG) therapy. The therapy is the first intravesical drug-releasing system designed to deliver continuous local release of chemotherapy directly into the bladder, according to the company. It is indicated for patients with BCG-unresponsive NMIBC with carcinoma in situ, with or without papillary tumors, and may provide a bladder-sparing alternative to radical cystectomy. Inlexzo is designed to be inserted in the bladder for three weeks per treatment cycle and can be used for up to 14 cycles, it says.
Approval was based on data from the Phase 2b SunRISe-1 trial, which found that 82% of patients achieved a complete response, with more than half maintaining that response for at least a year. The most common adverse events included urinary tract infections, bladder irritation, and changes in lab values such as decreased hemoglobin and increased creatinine.
Bladder cancer is among the most common cancers in the U.S., with NMIBC making up the majority of cases, according to the company. Patients who fail BCG treatment are often advised to undergo radical cystectomy, a surgery associated with significant risks and quality-of-life impacts, it says.
