WVE-006 is the most advanced candidate for AATD designed to restore functional wild-type AAT protein and reduce Z-AAT protein aggregation with potential for disease modification in both lung and liver phenotypes
IND-enabling activities for WVE-006 are underway and Wave expects to submit clinical trial applications for WVE-006 in 2023
Wave is also pioneering new therapeutic applications for RNA editing, including activating gene pathways and upregulating gene expression
CAMBRIDGE, Mass., Sept. 28, 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 hosted a virtual event, “Towards the Clinic: Spotlight on RNA Editing for AATD,” highlighting its WVE-006 program, which is Wave’s preclinical A-to-I RNA base editing oligonucleotide (“AIMer”) candidate for the treatment of alpha-1 antitrypsin deficiency (AATD). The event featured a presentation from an AATD clinical expert, D. Kyle Hogarth, MD, FCCP, Professor of Medicine in the Section of Pulmonary and Critical Care Medicine at the University of Chicago. The company also outlined future therapeutic applications of its leading RNA editing capability, including modulating protein interactions as well as addressing diseases outside the liver. A replay of the event and slide presentation are available here.
“Wave continues to lead the genetic medicines field in advancing therapeutic RNA editing toward the clinic with our WVE-006 AIMer program and we expect to submit clinical trial applications for our first-in-human study in 2023. WVE-006 is distinct from other approaches in development for AATD, as it offers the opportunity to treat the root genetic cause of the disease and restore functional, wild-type protein that remains under physiological regulation. This would be a holistic solution and applicable to those with lung disease, liver disease, or both,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. “Additionally, the opportunity for AIMers is much broader than restoring or correcting protein function in genetic diseases, as we demonstrated today with our preclinical data supporting the use of AIMers to modulate protein-protein interactions and upregulate gene expression. RNA editing is emerging as a distinct class of therapeutics with potential to address disease biology in novel and innovative ways and reach patients suffering from an array of diseases, including neurological disorders, as well as renal, cardiometabolic, or immunologic diseases. We are proud to be pioneers in this new area of genetic medicine and to have a best-in-class RNA editing capability with our AIMers.”
Highlights from today’s event, “Towards the Clinic: Spotlight on RNA Editing for AATD,” are below.
Best-in-Class Potential of WVE-006 for AATD
WVE-006 is a first-in-class, GalNAc-conjugated RNA editing candidate and the most advanced program currently in development using an oligonucleotide to harness an endogenous enzyme for editing. WVE-006 is designed to correct the single G-to-A base mutation in mRNA coded by the SERPINA1 Z allele, thereby enabling functional, wild-type M-AAT protein to be produced.
Data for WVE-006 highlighted today include:
WVE-006 Advancing Toward the Clinic
IND-enabling activities for WVE-006 are underway and Wave expects to submit clinical trial applications (CTAs) for WVE-006 in 2023.
In addition, Wave announced today initial plans for the anticipated first-in-human study of WVE-006. This Phase 1/2 study would evaluate safety, pharmacokinetics, and relevant biomarkers, including serum AAT. The study, which would use Wave’s adaptive design approach, is expected to first enroll healthy volunteers to establish dose, followed by cohort expansion with Pi*ZZ patients to evaluate target engagement based on change in serum AAT levels.
Future Applications of AIMers
Wave is advancing research using AIMers for applications beyond correction of G-to-A driver mutations and today highlighted preclinical data supporting the use of AIMers to activate gene pathways and upregulate gene expression. These applications would significantly expand the universe of targets addressable with AIMers, including diseases with large patient populations. Highlights from the presentation include:
Wave is also advancing research using AIMers beyond hepatocytes and using free uptake instead of GalNAc conjugation. Preclinical in vivo data supports the ability to edit with systemic delivery in multiple tissues, including heart, kidney, lung, spleen, liver, white adipose tissue, and brown adipose tissue. Wave has also generated in vivo data demonstrating substantial and durable editing and supporting administration of AIMers with intrathecal or intracerebroventricular delivery in central nervous system tissues.

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 Alpha-1 antitrypsin deficiency (AATD)
Alpha-1 antitrypsin deficiency (AATD) is an inherited genetic disorder that is commonly caused by a G-to-A point mutation (“Z allele”) in the SERPINA1 gene. This mutation leads to lung disease due to lack of wild-type alpha-1 antitrypsin (M-AAT) in lungs and liver disease due to aggregation of misfolded Z-AAT protein in hepatocytes. There are approximately 200,000 patients in the United States and Europe who have Z mutations on both alleles, known as the PiZZ genotype. Augmentation therapy is the only treatment option for AATD lung disease and requires weekly intravenous infusions. There are no treatments for AATD liver disease, other than liver transplant. The average age of diagnosis of AATD lung disease is 46 years and the average age of adult-onset liver disease is 61 years.
