Seelos Therapeutics Announces European Medicines Agency Guidance to Design an Open-Label Pivotal Study for SLS-005 in Sanfilippo Syndrome

New York, New York, UNITED STATES

NEW YORK, March 11, 2020 (GLOBE NEWSWIRE) -- Seelos Therapeutics, Inc. (Nasdaq: SEEL), a clinical-stage biopharmaceutical company focused on the development of therapies for central nervous system disorders and rare diseases, announced that it has received a written response from the European Medicines Agency (EMA), in lieu of a face to face meeting, offering guidance for Seelos’ planned European study of SLS-005 (IV trehalose) in patients with mucopolysaccharidosis type III (MPS III), also known as Sanfilippo syndrome.

Based upon the written response from the EMA, Seelos will design an open-label, non-placebo controlled, Phase IIb/III pivotal study for the treatment of patients with Sanfilippo syndrome types A and B in the European Union (EU).

“The EMA’s recommendation to use appropriate natural history data of Sanfilippo syndrome patients allows us to offer active therapy to all children enrolled in the study,” said Raj Mehra, Ph.D., Chairman and CEO of Seelos. “This devastating disease currently lacks any approved treatment and we look forward to taking this next step in advancing our SLS-005 program.”

About Trehalose

Trehalose is a low molecular weight disaccharide (0.342 kDa) that crosses the blood brain barrier, stabilizes proteins and, importantly, activates autophagy, which is the process that clears material from cells. In animal models of several diseases associated with abnormal cellular-protein aggregation or storage of pathologic material, has been shown to reduce aggregation of misfolded proteins and reduce accumulation of pathologic material. Trehalose activates autophagy through the activation of Transcription Factor EB (TFEB), a key factor in lysosomal and autophagy gene expression. Activation of TFEB is an emerging therapeutic target for a number of diseases with pathologic accumulation of storage material.
