Wave Life Sciences to Present New Data on Its DMD Exon 53 Skipping Program and Discovery Platform at Upcoming Meetings

September 20, 2018

CAMBRIDGE, Mass., Sept. 20, 2018 (GLOBE NEWSWIRE) -- Wave Life Sciences Ltd. (NASDAQ: WVE), a biotechnology company focused on delivering transformational therapies for patients with serious, genetically-defined diseases, today announced presentations at two upcoming meetings highlighting new data on the company’s Duchenne muscular dystrophy (DMD) exon 53 skipping program and the company’s proprietary chemistry platform.

23rd International Annual Congress of the World Muscle Society

A poster entitled “Identification of Potent, Muscle-Targeting Investigational Stereopure Oligonucleotides for Exon 53 DMD Therapy” (Poster #127) will be presented on October 3, 2018 at 4:00 pm ART at the 23rd International Annual Congress of the World Muscle Society in Mendoza, Argentina. The poster will include new data from a stereopure exon 23 skipping oligonucleotide demonstrating substantial and durable dystrophin protein restoration across multiple muscle tissues, including heart, in the mdx 23 mouse model of DMD. Wave’s exon 53 skipping program is in preclinical development and leverages the company’s ongoing neuromuscular research and in vivo data supporting the development of WVE-210201, the company’s lead exon 51 skipping investigational oligonucleotide in DMD.

WVE-210201 is currently being studied in a global Phase 1 clinical trial in DMD patients amenable to exon 51 skipping. As patients complete the Phase 1 trial, they have the option to enroll in an ongoing open-label extension study in which they continue to receive WVE-210201.

14th Annual Meeting of the Oligonucleotide Therapeutics Society (OTS)

A presentation entitled “Stereochemical Control of Antisense Oligonucleotides Enhances Target Efficacy” will take place on October 3, 2018 at 11:00 am PDT at the 14th Annual Meeting of the Oligonucleotide Therapeutics Society in Seattle, Washington. The presentation will be given by Chandra Vargeese, PhD, Senior Vice President and Head of Discovery at Wave.

Wave will also present the following three posters at this meeting:

-- “Optimized, Stereopure Antisense Oligonucleotides Achieve Broad Tissue Distribution and Excellent Exposure, Enabling Potent and Durable Knockdown of Nuclear Malat1 in Mice and Nonhuman Primates” (Poster #030) -- “A Bicyclic Synthetic Ligand for ASGR is a Safe Alternative to GalNAc for Effective Hepatocyte-specific Delivery in Mouse Models” (Poster #092) -- “Cellular Free-Uptake Models for Optimized, Stereopure Antisense Oligonucleotides Predict Exon Skipping Efficiency and Dystrophin Protein Restoration in Mice” (Poster #119)

Data from the presentation and the three posters highlight advances in Wave’s novel chemistry platform and its ability to precisely design, optimize and manufacture stereopure oligonucleotides.
