NEW YORK, Nov. 22, 2013 (GLOBE NEWSWIRE) -- Stemline Therapeutics, Inc. (Nasdaq:STML) announced today that clinical trial results of a synthetic peptide vaccine for brain cancer, now being developed as SL-701, will be presented by investigators from the University of Pittsburgh at the 4th Quadrennial Meeting of the World Federation of Neuro-Oncology (WFNO) being held in conjunction with the 18th Annual Society for Neuro-Oncology (SNO) meeting in San Francisco, California on November 21-24, 2013. SL-701 is a subcutaneously-administered cancer vaccine comprised of multiple synthetic peptides corresponding to targets on tumor bulk and cancer stem cells (CSCs).
The synthetic peptide vaccine developed by the University of Pittsburgh has previously demonstrated single-agent clinical efficacy, including complete responses (CRs), in Phase 1/2 trials in both adults and children with high-grade glioma (HGG), including glioblastoma multiforme (GBM). Based on these results, Stemline, who licensed patent rights relating to the Pitt vaccine from the University of Pittsburgh, is planning registration-directed programs in both adults and children with HGG.
According to a research abstract published on the SNO meeting website, University of Pittsburgh investigators will report on the safety and immunological responses achieved with the Pitt vaccine in an additional indication, adults with newly diagnosed or recurrent low-grade glioma (LGG) (n=23). The Pitt Vaccine was determined to be well-tolerated and induced specific and sustained immune responses against its brain tumor targets. Further, patients with a high magnitude of immunologic responsiveness experienced prolonged progression free survival (PFS).
Eric Rowinsky, M.D., Chief Medical Officer and Head of Research and Development of Stemline, commented, "Our immediate plans now are to advance SL-701 into late-stage trials in HGG, including a potentially accelerated approval pathway in adults with second-line GBM, and in children with brainstem and non-brainstem glioma for which there are no approved therapies. We will also continue to monitor the ongoing Pittsburgh trial in LGG, another area of unmet medical need, and consider advancement in this indication as well."
Details on the presentation are as follows:
Robust induction of type-1 CD8+ T-cell responses in WHO grade II low-grade glioma patients receiving peptide-based vaccines (SL-701) in combination with poly-ICLC (IT-013)
Presenter: Hideho Okada, M.D., Ph.D., Professor of Neurological Surgery, Surgery and Immunology, University of Pittsburgh, Pittsburgh, PA.
Date/Time: Saturday, November 23, 2013; 5:00-7:00 pm PT
About Stemline Therapeutics, Inc.
Stemline Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing novel oncology therapeutics that target both cancer stem cells (CSCs) as well as the tumor bulk. Stemline's clinical candidates, SL-401 and SL-701, have demonstrated clinical activity, including durable complete responses (CRs), in Phase 1/2 studies of patients with advanced hematologic and brain cancer, respectively. SL-401 is being advanced into pivotal programs in blastic plasmacytoid dendritic cell neoplasm (BPDCN) and third-line acute myeloid leukemia (AML) as well as other clinical studies in additional hematologic cancers. SL-701 is being advanced into later stage trials of adults with second-line glioblastoma multiforme (GBM) and children with brainstem and non-brainstem glioma.
