Wave Life Sciences to Highlight Advancements from PRISM Platform at Upcoming Scientific Congresses

Wave Life Sciences USA, Inc.
Wave Life Sciences USA, Inc.

Six presentations and posters between OTS and ESGCT meetings will highlight Wave’s oligonucleotide chemistry advancements as well as RNA editing and RNAi capabilities

First presentation in a scientific congress of preclinical data supporting WVE-006 as a potential best-in-class therapeutic approach in alpha-1 antitrypsin deficiency

CAMBRIDGE, Mass., Oct. 03, 2022 (GLOBE NEWSWIRE) -- Wave Life Sciences Ltd. (Nasdaq: WVE), a clinical-stage genetic medicines company committed to delivering life-changing treatments for people battling devastating diseases, today announced it will highlight oligonucleotide chemistry advancements from the company’s PRISMTM discovery and drug development platform at upcoming scientific conferences. The company will also highlight its A-to-I RNA base editing oligonucleotides (AIMers), including WVE-006 for alpha-1 antitrypsin deficiency (AATD), as well as its RNA interference (RNAi) capabilities. The scientific congresses include the 18th Annual Meeting of the Oligonucleotide Therapeutics Society (OTS), taking place October 2-5, 2022, and the European Society of Gene & Cell Therapy 29th Congress (ESGCT), taking place October 11-14, 2022.

“Wave continues to expand its genetic medicines toolkit of modalities and novel chemistries, enabling both the flexibility to optimally address disease biology, as well as the ability to fine-tune potency, durability of effect, and tissue distribution of our stereopure oligonucleotides. Our data at OTS and ESGCT are illustrative of both the evolution and the potential of Wave’s science,” said Chandra Vargeese, PhD, Chief Technology Officer and Head of Platform Discovery Sciences at Wave Life Sciences. “We are excited to share the preclinical data for WVE-006 – the most advanced program to harness an endogenous enzyme for editing – as well as how we are applying AIMers to upregulate gene expression. We also are highlighting our preclinical siRNA designed with PRISM chemistry, which demonstrates remarkably robust and durable RNA silencing in vivo. Underpinning all of these advancements is our next-generation PN backbone chemistry and the enhanced pharmacology enabled by control of stereochemistry.”

About AIMers
Wave’s AIMers are designed to correct mutations in an RNA transcript, thereby avoiding permanent changes to the genome that occur with DNA-targeting approaches. Rather than using an exogenous editing enzyme, AIMers recruit proteins that exist in the body, called ADAR enzymes, which naturally edit certain adenine (A) bases to inosine (I). Because I is read as G (guanine) by the cellular translational machinery, sequence-directed editing with ADAR has the potential to revert transcripts with single G-to-A point mutations that cause genetic diseases. This approach redirects a natural system for therapeutic purposes, enables simplified delivery without viral particles or liposomes, and avoids the risk of irreversible off-target effects of DNA-targeting approaches. AIMers are short in length, fully chemically modified, and use novel chemistry, including proprietary PN backbone modifications and chiral control, that make them distinct from other ADAR-mediated editing approaches.

About PRISM™
PRISM is Wave Life Sciences’ proprietary discovery and drug development platform that enables genetically defined diseases to be targeted with stereopure oligonucleotides across multiple therapeutic modalities, including silencing, splicing, and editing. PRISM combines the company’s unique ability to construct stereopure oligonucleotides with a deep understanding of how the interplay among oligonucleotide sequence, chemistry and backbone stereochemistry impacts key pharmacological properties. By exploring these interactions through iterative analysis of in vitro and in vivo outcomes and machine learning-driven predictive modeling, the company continues to define design principles that are deployed across programs to rapidly develop and manufacture clinical candidates that meet pre-defined product profiles.

About Wave Life Sciences
Wave Life Sciences (Nasdaq: WVE) is a clinical-stage genetic medicines company committed to delivering life-changing treatments for people battling devastating diseases. Wave aspires to develop best-in-class medicines across multiple therapeutic modalities using PRISM, the company’s proprietary discovery and drug development platform that enables the precise design, optimization, and production of stereopure oligonucleotides.
