In vivo data after single-dose IV administration demonstrate engagement with DMPK mRNA and broad rescue of mis-splicing across key transcripts

Findings provide support for hypothesized mechanism of action of anti-gene, which is designed to not degrade the DMPK transcript

Data further validate the potential of the PATrOL platform to develop highly targeted therapies that increase, decrease or change causal protein function

PITTSBURGH, Pa., Dec. 16, 2020 (GLOBE NEWSWIRE) -- NeuBase Therapeutics, Inc. (Nasdaq: NBSE) ("NeuBase" or the "Company"), a biotechnology company accelerating the genetic revolution using a new class of synthetic medicines, today announced positive in vitro and in vivo preclinical data for its PATrOL-enabled anti-gene therapies for the treatment of myotonic dystrophy type 1 (DM1). These new data show that PATrOL-enabled Compound A can rapidly resolve mis-splicing without negatively impacting DMPK protein levels. They also support the potential of NeuBases anti-gene approach to comprehensively treat the underlying cause of DM1.

Despite the fact that the genetic basis of DM1 is well understood today, there is still an urgent need to find the first genetically-targeted, disease-modifying treatment option for affected patients, said Curt Bradshaw, Ph.D., Chief Scientific Officer of NeuBase. DM1 is caused by a genetic mutation in the DMPK gene leading to mis-splicing of a broad spectrum of genes and DMPK protein insufficiency. A treatment option that addresses mis-splicing while retaining functional DMPK protein levels may be key to treating all aspects of DM1.

Dietrich A. Stephan, Ph.D., Chief Executive Officer of NeuBase, added, Using our proprietary PATrOL platform, we have designed a first-in-class anti-gene candidate that selectively binds mutant DMPK mRNA and opens its hairpin secondary structure, as opposed to a mechanism of action that explicitly degrades the mutant and wild-type transcripts indiscriminately, making it a unique option for the treatment of DM1. These in vitro and in vivo data both support our hypothesized mechanism of action and demonstrate rapid and broad resolution of the mis-splicing that is the primary cause of DM1.

This is the second set of positive data that weve announced in 2020 for our PATrOL-enabled therapies, which we believe serves as proof of concept that further validates our technologic foundation. With a single unified platform, we believe we can increase, decrease or change protein function of potentially any nucleic acid target, unique among genetic medicine approaches. We are excited by the progress we have made and look forward to providing additional updates on our platform and pipeline of programs at an R&D day in the first half of 2021.

In vivo data highlights in the HSALR transgenic mouse model of DM1 that expresses high levels of mutant CUG-repeat-containing mRNA (HSA) in skeletal muscle:

DM1 is a rare, autosomal dominant repeat expansion disorder characterized by progressive muscle wasting and weakness. It also affects the central nervous system (CNS) and heart. DM1 is caused by CTG nucleic acid repeats in the DMPK gene that produce a hairpin structure in the transcribed DMPK mRNA. The hairpin structure sequesters critical splice regulators and results in the mis-splicing of multiple gene transcripts. Furthermore, the binding of splice regulators traps the mutant DMPK mRNA in the nucleus, resulting in DMPK protein haploinsufficiency, or half the level of protein that is needed for normal function, which is thought to exacerbate the CNS and cardiac symptoms that are characteristic of DM1 (as knock-out mice for Dmpk show both severe cardiac conduction defects as well as issues with neuronal cytoskeletal remodeling manifesting in aberrant long-term potentiation). The prevalence of DM1 is >5/100,000 in the general population. There are currently no approved treatments for DM1.
