About Stemline Therapeutics

Stemline Therapeutics, Inc. is a clinical stage biopharmaceutical company developing novel oncology therapeutics that target cancer stem cells (CSCs) and tumor bulk. Stemline is developing two clinical stage product candidates, SL-401 and SL-701, and preclinical candidates that include SL-801. SL-401 is a targeted therapy directed to the interleukin-3 receptor (IL-3R) present on CSCs and tumor bulk of a wide range of hematologic cancers. Several multicenter clinical trials with SL-401 are currently open in a variety of indications. Patients are currently being enrolled in the expansion stage of the SL-401 pivotal trial in relapsed/refractory blastic plasmacytoid dendritic cell neoplasm (BPDCN). This follows recent completion of the lead-in stage of this trial that enrolled first-line and relapsed/refractory BPDCN and relapsed/refractory acute myeloid leukemia (AML) patients at escalating doses and confirmed the dose and schedule for the current expansion stage. A previous Phase 1/2 trial with SL-401 demonstrated major responses, including complete responses (CRs), in both first-line and relapsed/refractory BPDCN as well as relapsed/refractory AML. Clinical studies with SL-401 are also open in additional malignancies including AML in CR with minimal residual disease (MRD) and several high-risk myeloproliferative neoplasms (MPN). SL-701, an immunotherapy designed to activate the immune system to attack tumors, is being developed in adult patients with second-line glioblastoma multiforme (GBM). SL-801, a novel oral small molecule reversible inhibitor of XPO1, is currently being advanced toward investigational new drug (IND) filing for clinical development in a variety of solid and hematologic cancers.
