Johnson & Johnson reports that data from Cohort 2 of the Phase 2b SunRISe-1 study evaluating investigational TAR-200 monotherapy in patients with Bacillus Calmette-Guérin (BCG)-unresponsive high-risk, non–muscle-invasive bladder cancer (HR-NMIBC) with carcinoma in situ showed a high complete response rate and durability of response. The study is evaluating the therapy in patients who are ineligible for, or decline, radical cystectomy.

The results of 85 patients who received TAR-200 monotherapy showed a complete response rate of 82.8% by urine cytology and/or biopsy, the company says. The estimated one-year duration of response rate is 74.6%, adding that 41 of 48 responders (85%) remained in complete response status at the data cutoff (1/2/2024), it adds.

TAR-200 is an investigational drug-device targeted releasing system designed to provide extended local release of gemcitabine into the bladder, J&J says. It is installed in a physician’s office during a three to five minute procedure with no anesthesia. Late last year, FDA granted TAR-200 a Breakthrough Therapy Designation (BTD) for the potential future treatment of patients with BCG-unresponsive HR-NMIBC.
