Compelling first results from Cohort 4 of Phase 2b SunRISe-1 study show potential of TAR-200 monotherapy in patients with papillary-only, high-risk non-muscle invasive bladder cancer

Johnson & Johnson announced that new data from its leading oncology pipeline will be presented at the American Urological Association (AUA) 2025 Annual Meeting, taking place April 26-29 in Las Vegas. Among the highlights are the 12-month duration of response (DOR) data from the Phase 2b Cohort 2 SunRISe-1 study, evaluating TAR-200—an intravesical gemcitabine releasing system—for patients with Bacillus Calmette-Guérin (BCG)—unresponsive, high-risk non-muscle-invasive bladder cancer (HR-NMIBC) with carcinoma in situ (CIS) with or without papillary disease. These findings will be featured in the Practice-changing, Paradigm-shifting Clinical Trials in Urology plenary session on Saturday, April 26.

Bladder cancer ranks among the top ten most common cancers worldwide, affecting nearly a million people each year.1 Despite advancements, standard treatment has remained largely unchanged for over 40 years, leaving patients with limited treatment options if initial BCG therapy does not work.2 TAR-200 delivers sustained medication directly into the bladder and, in a pre-clinical setting, has been shown to allow for depth of penetration across bladder tissue layers.3

“Patients with bladder cancer need more effective treatment options that are both tolerable and easily incorporated into everyday practice, especially for those with HR-NMIBC, a highly recurrent disease that often necessitates difficult, life-altering decisions like bladder removal,” said Yusri Elsayed, M.D., M.H.Sc., Ph.D., Global Therapeutic Area Head, Oncology, Johnson & Johnson Innovative Medicine. “TAR-200 provides a new approach, with clinical data showing an impressive complete response rate, meaning the cancer was undetectable following treatment. The highly anticipated 12-month duration of response findings from our Cohort 2, SunRISe-1 study further support the potential for patients to remain cancer-free for a clinically meaningful period.”

A second plenary presentation will feature first results from Cohort 4 of the Phase 2b SunRISe-1 study evaluating TAR-200 monotherapy in patients with BCG–unresponsive, papillary-only HR-NMIBC. In this patient population, bladder removal remains a standard treatment, but many patients are elderly, have significant comorbidities, or are unwilling to undergo radical surgery, making treatment challenging.4

“Patients deserve more than the currently available treatment options. TAR-200 is a groundbreaking therapy for early-stage bladder cancer, designed to deliver a sustained local release of medication directly into the bladder—right where it is needed,” said Biljana Naumovic, U.S. President, Oncology, Solid Tumor, Johnson & Johnson Innovative Medicine. “This innovation provides a bladder-sparing treatment option that can meaningfully improve outcomes while integrating seamlessly into any urology practice.”

TAR-200 is inserted directly into the bladder by a healthcare professional in a brief outpatient, in-office procedure, without the need for anesthesia. Designed to remain in the bladder, it does not interfere with daily activities and provides sustained release of medication throughout the day. To date, TAR-200 has been placed more than 10,000 times as part of the SunRISe clinical program.

AUA 2025 Presentation Highlights:

  • First results from Cohort 4 of the Phase 2b SunRISe-1 study evaluating TAR-200 monotherapy in patients with BCG–unresponsive papillary-only HR-NMIBC 
  • Trial-in-progress mini-oral presentation from the Phase 3 MoonRISe-1 study evaluating TAR-210, an erdafitinib intravesical drug-releasing system, versus intravesical chemotherapy in patients with fibroblast growth factor receptors (FGFR)-altered intermediate-risk NMIBC (Clinical Trials in Progress Presentation). 
  • Trial-in-progress presentation from the Phase 3 SunRISe-5 study evaluating TAR-200 compared to intravesical chemotherapy after treatment with BCG in patients with recurrent HR-NMIBC (Clinical Trials in Progress Presentation).
