NEW YORK, NY, USA I March 11, 2019 I Stemline Therapeutics, Inc. (Nasdaq: STML), a commercial-stage biopharmaceutical company focused on the development and commercialization of novel oncology therapeutics, announced today that it has exclusively licensed worldwide rights to develop and commercialize a novel, oral, selective small molecule RET (rearranged during transfection) kinase inhibitor from the CRT Pioneer Fund LP, a £70 million specialist oncology investment fund managed by Sixth Element Capital, a UK based fund manager. The RET inhibitor was rationally designed by scientists at Cancer Research UK Manchester Institute at the University of Manchester (United Kingdom). The preclinical compound has been designated SL-1001 and is expected to enter the clinic in 2020.
RET kinase genetic alterations have been found in a diverse range of cancers and, we believe, is a clinically validated target in multiple indications. SL-1001 is an oral RET kinase inhibitor that has demonstrated potent, selective, preclinical anti-cancer activity, both in vitro and in vivo, in RET-driven tumor models.
“SL-1001 is an ideal strategic fit for us, given its targeted mechanism of action and potential for streamlined development,” commented Stemline’s CEO, Ivan Bergstein. He continued, “Building upon our team’s proven track record of success, culminating with the recent ELZONRIS approval, we intend to advance SL-1001 swiftly through the clinical and regulatory process with an eye towards achieving our goal of helping more patients succeed in their fight against cancer.”
Robert James, Managing Partner at Sixth Element Capital said, “We are delighted to have partnered SL-1001 with Stemline. We are confident that Stemline’s skills and resources will take the project forward rapidly and offer an alternative treatment option to patients with cancer driven by RET kinase”.
About Stemline Therapeutics
Stemline Therapeutics, Inc. is a biopharmaceutical company focused on the development and commercialization of novel oncology therapeutics. In December 2018, the FDA approved ELZONRIS, a targeted therapy directed to CD123, for the treatment of adult and pediatric patients, two years or older, with blastic plasmacytoid dendritic cell neoplasm (BPDCN). In November 2018, the European Medicines Agency (EMA) granted accelerated assessment to the marketing authorization application (MAA) of ELZONRIS for the treatment of patients with BPDCN, which was submitted to, and validated by, the EMA in January 2019. ELZONRIS is also being evaluated in clinical trials in additional indications including chronic myelomonocytic leukemia (CMML), myelofibrosis (MF) and acute myeloid leukemia (AML). Additional pipeline candidates include: SL-701 (immunotherapeutic; Phase 2 in glioblastoma patients completed), SL-801 (XPO1 inhibitor; Phase 1 in advanced solid tumor patients ongoing), SL-901 (novel kinase inhibitor; prior abbreviated European Phase 1, IND-enabling studies ongoing), and SL-1001 (novel RET kinase inhibitor, IND-enabling studies pending).
ELZONRIS (tagraxofusp), a CD123-directed cytotoxin, was approved by the Food and Drug Administration (FDA) on December 21, 2018 for the treatment of adult and pediatric patients, two years and older, with blastic plasmacytoid dendritic cell neoplasm (BPDCN).

BPDCN is an aggressive hematologic malignancy with historically poor outcomes and an area of unmet medical need. BPDCN typically presents in the bone marrow and/or skin and may also involve lymph nodes and viscera. The BPDCN cell of origin is the plasmacytoid dendritic cell (pDC) precursor. The diagnosis of BPDCN is based on the immunophenotypic diagnostic triad of CD123, CD4, and CD56, and other markers.
