SunRISe-1

A tiny pretzel-shaped device that slowly releases chemotherapy inside the bladder cleared carcinoma in situ in over 80% of patients whose BCG had failed.

Cohort 2 (TAR-200 alone): confirmed CR 82%; 51% remained in CR at 1 year; 98% of responses within 12 weeks. FDA approval of Inlexzo (gemcitabine intravesical system) on 9 September 2025 for BCG-unresponsive NMIBC with CIS. Cetrelimab added little. Phase 3 SunRISe-3 (BCG-naive) and SunRISe-4 (MIBC) ongoing.

In plain words
What these results mean for people, not percentages
Complete response rate (CIS)primaryresponse endpoint
  • 82 out of 100 people had their tumour shrink with TAR-200 monotherapy.
  • A response rate counts how many people had their tumours shrink by a set amount; shrinking is encouraging but does not by itself show that people live longer or feel better.
Duration of CR ≥12 monthssurrogate endpoint
  • 51 out of 100 people reached this endpoint with TAR-200 monotherapy.
  • This is a surrogate endpoint: it measures the cancer being controlled or absent on scans and tests, which often, but not always, translates into living longer.
Be careful
  • There was no comparison group, so this number cannot tell you how much of the effect is due to the treatment.
  • These results apply to the people the trial enrolled: BCG-unresponsive high-risk NMIBC with carcinoma in situ: TAR-200 (gemcitabine intravesical system) ± cetrelimab, single-arm cohorts. People in a different situation may not see the same effect.
