Studies suggest improved outcomes for dual checkpoint inhibition with high ipilimumab doses. We aimed to examine the safety and activity of nivolumab induction and high-dose ipilimumab as an immunotherapeutic boost as a second-line treatment for patients with metastatic urothelial carcinoma.TITAN-TCC is a multicentre, single-arm, phase 2 trial done at 19 hospitals and cancer centres in Germany and Austria. Adults aged 18 years or older with histologically confirmed metastatic or surgically unresectable urothelial cancer of the bladder, urethra, ureter, or renal pelvis were eligible. Patients had to have progression during or after first-line platinum-based chemotherapy and up to one more second-line or third-line treatment, a Karnofsky Performance Score of 70 or higher, and measurable disease as per Response Evaluation Criteria in Solid Tumors version 1.1. After four doses of intravenous nivolumab 240 mg induction monotherapy every 2 weeks, patients with a partial or complete response at week 8 continued maintenance nivolumab, whereas those with stable or progressive disease (non-responders) at week 8 received a boost of two or four doses of intravenous nivolumab 1 mg/kg plus ipilimumab 3 mg/kg every 3 weeks. Patients who subsequently had progressive disease during nivolumab maintenance also received a boost, using this schedule. The primary endpoint was the confirmed investigator-assessed objective response rate in the intention-to-treat population and had to exceed 20 LB - PUB:(DE-HGF)16 C6 - pmid:36868252 DO - DOI:10.1016/S1470-2045(23)00053-0 UR - https://inrepo02.dkfz.de/record/274133 ER -
