Title:
RC48-ADC combined with toripalimab, an anti-PD-1 monoclonal antibody (Ab), in patients with locally advanced or metastatic urothelial carcinoma (UC): Preliminary results of a phase Ib/II study.
Published date:
05/19/2021
Excerpt:
...The primary site was in upper tract UC in 50%; 50% had visceral metastases (mets), including 36% with liver mets; HER2 expression was positive (IHC 3+ or 2+ ISH+) in 28%, and 43% PD-L1 CPS≥10. A total of 36 pts is anticipated to be enrolled by Apr 2021. No dose limiting toxicity was reported and the recommended dose for RC48-ADC was 2mg/kg. At data cutoff, 10/14 patients were evaluable for response, with 8 PR, 1 SD (tumor shrinking), and 1 PD. The objective response rate (ORR) was 80%, and disease control rate (DCR) was 90%...RC48-ADC in combination with toripalimab had a good tolerance and
