ELZONRIS is the first and only approved treatment for BPDCN, a deadly hematologic cancer.1,2
Efficacy in treatment-naïve patients (N=29)3*
CR/CRc rate†
ORR
bridged to stem cell transplantation
- The median duration of CR/CRc has not yet been reached; median follow-up 19 months (range, 1-42 months)3
- The median time to CR/CRc was 43 days (range, 14-131 days)3
- The median time from the first dose to stem cell transplantation (SCT) was 4.4 months (range, 76-203 days)4
Efficacy in the pivotal cohort (N=13)1,4
CR/CRc rate†
ORR
bridged to stem cell transplantation
- The median duration of CR/CRc has not yet been reached (range, 3.9-12.2 months)1
- The median time to CR/CRc was 57 days (range, 14-107 days)1
In other cohorts (N=16)4
- Efficacy measures included 88% CR/CRc rate,† 100% ORR, and 44% bridged to stem cell transplantation4
- The median duration of CR/CRc has not yet been reached (range, 1.3-32.2 months)4
*All-cohorts population includes patients from the pivotal cohort.
†CRc = clinical complete response; defined as complete response with residual skin abnormality not indicative of active disease.1
BPDCN = blastic plasmacytoid dendritic cell neoplasm; CR = complete response; ORR = overall response rate.
