QUILT 3.032

An IL-15 booster given with BCG produced complete responses in about 70% of patients with BCG-unresponsive carcinoma in situ and kept most bladders intact for years.

CR 71% in CIS cohort; median duration of CR ~26 months; bladder preservation >80% at 3 years in responders (company 5-year update). FDA approval 22 April 2024 after a 2023 complete response letter over manufacturing.

Setting
BCG-unresponsive NMIBC with CIS: nogapendekin alfa inbakicept (N-803) + BCG, single arm

Replication
Single-arm; QUILT 2.005 (BCG-naive) and BCG-unresponsive papillary cohorts extend the evidence.

Outcomes

In plain words
What these results mean for people, not percentages
Complete response rate (CIS)primaryresponse endpoint
  • 71 out of 100 people had their tumour shrink with N-803 + BCG.
  • There was no comparison group, so this number cannot tell you how much of the effect is due to the treatment.
  • 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.
  • These results apply to the people the trial enrolled: BCG-unresponsive NMIBC with CIS: nogapendekin alfa inbakicept (N-803) + BCG, single arm. People in a different situation may not see the same effect.

Numbers are from the trial as recorded here; see the source links in the table below. This is orientation, not medical advice: ask your team how closely the trial population matches you.
