14 CLINICAL STUDIES
14.1 First-Line Treatment of Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN)
STML-401-0114 (NCT 02113982; Study 0114) was a multicenter, open-label, single-arm, clinical trial that included a prospective cohort of 13 patients with treatment-naive BPDCN. Treatment consisted of ELZONRIS 12 mcg/kg intravenously over 15 minutes once daily on days 1 to 5 of a 21-day cycle. Patient baseline characteristics are presented in Table 5.
| Parameter | N=13 |
| Gender, N (%) | |
| Male | 11 (84.6) |
| Female | 2 (15.4) |
| Age (years), N (%) | |
| Median | 65.0 |
| Minimum, Maximum | 22, 84 |
| ECOG, N (%) | |
| 0 | 8 (61.5) |
| 1 | 5 (38.5) |
| BPDCN at Baseline, N (%) | |
| Skin | 13 (100.0) |
| Bone Marrow | 7 (53.8) |
| Peripheral Blood | 3 (23.1) |
| Lymph Nodes | 6 (46.2) |
| Viscera | 2 (15.4) |
The efficacy of ELZONRIS in patients with treatment-naive BPDCN was based on the rate of complete response or clinical complete response (CR/CRc). Key efficacy measures are presented in Table 6. The median time to CR/CRc was 57 days (range: 14 to 107).
| * CRc is defined as complete response with residual skin abnormality not indicative of active disease. | |
| Parameter | N=13 |
| CR/CRc* Rate, N (%) | 7 (53.8) |
| (95% CI) | (25.1, 80.8) |
| Duration of CR/CRc (months) | |
| Median | Not Reached |
| Minimum, Maximum | 3.9, 12.2 |
| Duration of follow up (months) | |
| Median | 11.5 |
| Minimum, Maximum | 0.2, 12.7 |
14.2 Relapsed or Refractory Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN)
STML-401-0114 (NCT02113982; Study 0114) was a multicenter, open-label, single-arm, clinical trial that included 15 patients with relapsed or refractory BPDCN. Treatment consisted of ELZONRIS 12 mcg/kg on days 1 to 5 of each 21-day cycle. Patient baseline characteristics are presented in Table 7.
| Parameter | (N=15) |
| Gender, N (%) | |
| Male | 13 (86.7) |
| Female | 2 (13.3) |
| Age (years) | |
| Median | 72 |
| Minimum, Maximum | 44, 80 |
| ECOG, N (%) | |
| 0 | 5 (33.3) |
| 1 | 10 (66.7) |
| BPDCN at Baseline, N (%) | |
| Skin | 13 (86.7) |
| Bone marrow | 9 (60.0) |
| Lymph node | 8 (53.3) |
| Visceral | 4 (26.7) |
| Peripheral blood | 1 (6.7) |
In the 15 patients with relapsed/refractory BPDCN, one patient achieved a CR (duration: 111 days) and one patient achieved a CRc (duration: 424 days).
