CAMBRIDGE, Mass., Jan. 08, 2024 (GLOBE NEWSWIRE) -- Wave Life Sciences Ltd. (Nasdaq: WVE), a clinical-stage biotechnology company focused on unlocking the broad potential of RNA medicines to transform human health, today announced key 2024 milestones across its clinical programs, growing pipeline, and leading RNA medicines platform.

“Wave is uniquely positioned to build the world’s leading RNA medicines company, with a clinically validated platform, diversified pipeline aimed at high-impact diseases, and meaningful commercial opportunities. Powered by multiple RNA modalities, a decade of chemistry innovation, and deep genetic insights, we are opening up new areas of disease biology and designing optimal ways of treating rare and common diseases. We expect 2024 will be an inflection year that will drive significant value for Wave, our shareholders, and most importantly, for the patients who will benefit from our research,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences.

Dr. Bolno continued: “This year, we expect the first-ever clinical proof-of-mechanism data for RNA editing with WVE-006 in AATD, which will accelerate additional Wave RNA editing programs. We are rapidly advancing our wholly owned INHBE program for obesity, which is designed to enable healthy, sustainable fat loss and address limitations of GLP1s. We also expect to deliver data demonstrating production of endogenous dystrophin protein in DMD with WVE-N531, as well as multidose data for WVE-003, our HD candidate that is uniquely designed to lower mutant huntingtin and maintain healthy, wild-type huntingtin. These programs underscore our drive to ‘Reimagine Possible’ for science, for medicine, and for human health.”

2024 Priorities and Anticipated Milestones

Advance AATD program to clinical proof-of-mechanism data and unlock additional opportunities for Wave’s leading RNA editing capability

WVE-006 in Alpha-1 Antitrypsin Deficiency (AATD) & RNA Editing

• WVE-006 is a GalNAc-conjugated, subcutaneously administered RNA editing oligonucleotide and is the first-ever RNA editing candidate to be evaluated in humans. WVE-006 is uniquely designed to correct the disease-causing SERPINA1 Z transcript mutation in AATD, thereby restoring circulation of wild-type M-AAT protein and reducing Z-AAT protein levels to address both lung and liver manifestations of the disease.
• In preclinical studies, WVE-006 demonstrated potent and durable editing of SERPINA1 Z transcript in mice, restoration of AAT protein up to 30 micromolar, and improvement in several markers of liver disease. WVE-006 is also highly specific with no evidence of bystander editing.
• In December 2023, Wave initiated dosing in healthy volunteers in the RestorAATion clinical trial program investigating WVE-006 as a potential treatment for AATD. RestorAATion includes healthy volunteers (RestorAATion-1) as well as individuals with AATD who have the homozygous PiZZ mutation (RestorAATion-2) and is designed to provide an efficient path to proof-of-mechanism as measured by restoration of M-AAT protein in serum.
• GSK has an exclusive global license to WVE-006 as part of its strategic collaboration with Wave. With initiation of dosing in RestorAATion, Wave achieved its first WVE-006 milestone under the collaboration, resulting in a $20 million payment from GSK. Wave is eligible to receive up to $505 million in additional development, launch, and commercial milestone payments, as well as tiered royalties on net sales, from GSK for WVE-006. Development and commercialization responsibilities will transfer to GSK after Wave completes the RestorAATion-2 study.
• Beyond WVE-006, Wave is advancing a pipeline of wholly owned RNA editing therapeutics across a range of high-impact GalNAc-hepatic and extra-hepatic targets.
• Expected milestones: Wave plans to deliver proof-of-mechanism data in individuals with AATD in 2024.

Advance INHBE program – first Wave wholly owned program to emerge from GSK collaboration – as well as progress GSK discovery programs under strategic collaboration

INHBE Program in Obesity

• Wave is advancing a novel approach for treating obesity with its GalNAc-small interfering RNA (siRNA) targeting INHBE, which is designed to induce fat loss while preserving muscle mass to restore and maintain metabolic health.
• This program is designed to silence the INHBE gene through RNA knockdown, thereby recapitulating the cardiometabolic profile of INHBE loss of function (LoF) heterozygous human carriers. These individuals exhibit reduced waist-to-hip ratio and reduced odds of type 2 diabetes and coronary artery disease. INHBE reduction of 50% or greater is expected to restore and maintain a healthy metabolic profile, while preserving muscle mass.
• In September 2023, Wave demonstrated the first in vivo proof-of-concept for INHBE silencing, with INHBE mRNA reduction in diet-induced obese mice well beyond the 50% therapeutic threshold, leading to substantially lower body weight and reduction of visceral fat as compared to control.
• Expected milestones: Wave has identified potent and highly specific INHBE siRNA leads and now expects to select an INHBE clinical candidate in the third quarter of 2024, ahead of expectation. This would enable clinical trial application (CTA) submission in 2025.

GSK Discovery Collaboration

• Wave continues to advance its discovery collaboration with GSK, which enables GSK to advance up to eight programs and Wave to advance up to three programs (inclusive of INHBE) leveraging Wave’s multimodal RNA medicines platform and GSK’s expertise in genetics and genomics.
• Wave is eligible for up to $3.3 billion in potential milestone payments for GSK’s eight collaboration programs and WVE-006, as well as royalties on net sales.
• Expected milestones: Advance collaboration activities with GSK, with potential for additional cash inflows in 2024.
  
  

Advance wholly owned DMD program with best-in-class exon skipping to potentially registrational dystrophin data

WVE-N531 in Duchenne Muscular Dystrophy (DMD)

• Wave’s WVE-N531 program for boys with DMD amenable to exon 53 skipping is designed to induce production of endogenous, functional dystrophin protein.
• Previous clinical data from the Phase 1b/2a Part A proof-of-concept trial of WVE-N531 in DMD demonstrated high muscle concentrations of WVE-N531 (mean of 42 micrograms/gram) and the highest level of exon skipping ever seen in the clinic (mean exon skipping of 53%; range: 48-62%) after three doses of 10 mg/kg every other week. WVE-N531 appeared safe and well-tolerated, with all treatment-related adverse events being mild.
• In December 2023, Wave announced the initiation of dosing in the potentially registrational Phase 2 FORWARD-53 study and also that the study was fully enrolled.
• Expected milestones: Wave expects to deliver data, including dystrophin protein expression from muscle biopsies at 24 weeks, in the third quarter of 2024.

Advance first-in-class, wild-type huntingtin-sparing HD program and deliver multi-dose data set for decision-making

WVE-003 in Huntington’s Disease (HD)

• WVE-003 is the most advanced investigational allele-selective HD therapeutic designed to reduce mutant huntingtin (mHTT) protein while also sparing healthy, wild-type huntingtin (wtHTT) protein, and is currently being evaluated in the 30 mg every-eight-week (Q8W) multi-dose cohort of the Phase 1b/2a SELECT-HD clinical trial.
• In a non-human primate (NHP) study, WVE-003 achieved significant tissue exposure levels in deep brain regions, including the striatum. These data bolstered Wave’s existing datasets that confirm the ability of its oligonucleotides to distribute to areas of the central nervous system associated with HD.
• WVE-003 has demonstrated single-dose reductions in mean cerebrospinal fluid mHTT of 35% compared to placebo, with preservation of wtHTT, as previously shared in September 2022.
• Expected milestones: Wave expects to report data from the 30 mg multi-dose cohort with extended follow-up, along with all single-dose data, in the second quarter of 2024. These data are expected to enable decision-making on the program and support the opt-in package for Takeda.

Cash runway

• Wave expects that its cash and cash equivalents, together with $115 million from its December 2023 offering and $27 million in recent collaboration milestones in the fourth quarter of 2023, will be sufficient to fund operations into the fourth quarter of 2025. Wave does not include future milestones or other contingent payments in its cash runway.

• Paul Bolno, MD, MBA, President and Chief Executive Officer, is scheduled to present at the 42^nd Annual J.P. Morgan Healthcare Conference in San Francisco, CA on Wednesday, January 10, 2024, at 3:00 p.m. PT / 6:00 p.m. ET.
