Investor conference call and webcast at 8:30 a.m. ET today

CAMBRIDGE, Mass., Nov. 09, 2023 (GLOBE NEWSWIRE) -- Wave Life Sciences Ltd. (NASDAQ:WVE), a clinical-stage RNA medicines company committed to delivering life-changing treatments for people battling devastating diseases, today announced financial results for the third quarter ended September 30, 2023, and provided a business update.

"The team has made tremendous progress during the past quarter as we solidified our leadership in RNA editing through the initiation of our clinical trial evaluating the first-ever RNA editing therapeutic, WVE-006. Additionally this quarter, we advanced our WVE-N531 (DMD) and WVE-003 (HD) clinical development programs and expanded our RNA therapeutic capabilities beyond rare diseases to common diseases with the announcement of our first GalNAc-conjugated siRNA program targeting INHBE to treat metabolic disorders, including obesity," said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. "As we shared during our recent R&D Day, we will sustain our leadership in RNA editing by building a pipeline of wholly owned editing candidates, each of which will have efficient paths to clinical proof-of-concept and represent significant commercial opportunities. With multiple, high impact clinical data readouts expected over the course of 2024 and plans to expeditiously deliver on a growing pipeline of RNA-targeting modalities, Wave is truly at an exciting inflection point."

Recent Business Highlights

• Initiated RestorAATion clinical program investigating WVE-006 as a treatment for alpha-1 antitrypsin deficiency (AATD). Wave recently initiated RestorAATion following approval of multiple clinical trial applications (CTAs). WVE-006 is uniquely designed to address AATD-related lung disease, liver disease, or both. The RestorAATion clinical program 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 wild-type alpha-1 antitrypsin (M-AAT) protein in serum. Wave expects to initiate dosing with WVE-006 in healthy volunteers in the fourth quarter of 2023 and deliver proof-of-mechanism data in individuals with AATD in 2024.
  
  
  
  
• Announced plans to advance a wholly owned pipeline of RNA editing candidates. Wave is utilizing its proprietary "edit-verse," which is powered by genetic datasets and deep learning models and designed to identify new RNA editing targets and edit sites. These targets leverage easily accessible biomarkers, offer efficient paths to proof-of-concept in humans, and represent meaningful commercial opportunities. Wave demonstrated in vivo and in vitro proof-of-concept data on several of these new targets, achieving at least 2-fold mRNA upregulation in liver and kidney targets and more than 60% mRNA correction in liver and lung targets.
  
  
  
  
• Announced new, wholly owned GalNAc-conjugated siRNA program targeting INHBE for metabolic disorders, including obesity, along with preclinical in vivo proof-of-concept data. INHBE loss-of-function heterozygous human carriers exhibit a healthy metabolic profile, including reduced waist-to-hip ratio and reduced odds of type 2 diabetes and coronary artery disease, and INHBE reduction of 50% or greater is expected to restore a healthy metabolic profile. Wave presented in vivo data at its recent R&D Day demonstrating INHBE silencing well beyond the 50% therapeutic threshold, which led to substantially lower body weight and reduction of visceral fat in diet-induced obesity mice as compared to control. These are the first in vivo data to demonstrate INHBE silencing is consistent with the phenotypes of heterozygous loss-of-function carriers. Wave has identified potent and highly specific leads and expects to select an INHBE clinical candidate in the fourth quarter of 2024. The INHBE program is Wave's first wholly owned program to emerge from its collaboration with GSK.
  
  
  
  
• Advancing potentially registrational Phase 2 FORWARD-53 clinical trial for WVE-N531. Wave remains on track to initiate dosing in FORWARD-53 in 2023 and enroll up to 10 boys in the trial. The clinical trial is powered to evaluate functional, endogenous dystrophin expression following 24 and 48 weeks of bi-weekly dosing. The primary endpoint will be dystrophin protein levels, and the trial will also evaluate pharmacokinetics, digital and functional endpoints, and safety and tolerability. Pending positive results from this trial, the company is planning to advance a broader DMD pipeline with PN-modified splicing oligonucleotides for skipping other exons, with the goal of providing new treatment options for a larger population of boys with DMD. Data from FORWARD-53 are expected in 2024.
  
  
  
  
• Delivered first clinical data in DMD demonstrating uptake in satellite cells after three biweekly doses. At Wave's annual R&D Day held in September 2023, the company highlighted clinical data from Part A of the Phase 1b/2a trial indicating that WVE-N531 was present in myogenic satellite cells, which is important for potential muscle regeneration. These are the first clinical data in DMD to demonstrate uptake in satellite cells at this early time point and further support the potential differentiation of WVE-N531 from other therapeutics, including gene therapies.
  
  
  
  
• Achievement of a non-clinical milestone under Takeda collaboration; NHP data supports broad distribution of WVE-003 in CNS. WVE-003 is the most advanced investigational HD therapeutic designed to reduce mutant huntingtin (mHTT) protein while also sparing healthy, wild-type huntingtin (wtHTT) protein, and previously demonstrated single-dose reductions in mean CSF mHTT of 35% as compared to placebo, with preservation of wtHTT, in September 2022. In the third quarter of 2023, Wave achieved a milestone in its collaboration with Takeda, which pertained to the positive results from a non-clinical study of WVE-003 in non-human primates (NHPs) and resulted in a payment of $7 million to Wave in the fourth quarter of 2023. This study showed significant tissue exposure levels of WVE-003 in the deep brain regions, including striatum, and bolstered Wave's existing datasets that confirm the ability of its oligonucleotides to distribute to the areas of the CNS important for HD.
  
  
  
  
• Completed enrollment in 30 mg multi-dose cohort of Phase 1b/2a SELECT-HD clinical trial for WVE-003 – the most advanced allele-selective investigational therapeutic for individuals with HD. Wave recently completed enrollment in the 30 mg multi-dose cohort of the SELECT-HD clinical trial, which is evaluating doses administered every eight weeks. Having rolled over patients from the single-dose cohort and fully enrolled the 30 mg multi-dose cohort, Wave will now evaluate the completed single-dose and multi-dose cohorts simultaneously. 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 company's opt-in package for Takeda.

Third Quarter 2023 Financial Results

Wave reported a net income of $7.3 million in the third quarter of 2023, as compared to a net loss of $39.0 million in the same period in 2022. The year-over-year change was primarily driven by the $48.9 million increase in revenue recognized under its collaborations. Under the Takeda collaboration, Wave earned $7.0 million dollars for the achievement of a WVE-003 non-clinical milestone. Additionally, under the Takeda collaboration, Wave recognized $28.0 million relating to the discontinuation of WVE-004 and under the GSK Collaboration, recognized $14.3 million.

Research and development expenses were $31.6 million in the third quarter of 2023, as compared to $27.6 million in the same period in 2022. The increase in research and development expenses was primarily driven by increased external expenses related to all three of Wave's clinical programs.

General and administrative expenses were $13.1 million in the third quarter of 2023, as compared to $11.6 million in the same period in 2022. The increase was primarily due to increased professional and consulting expenses as well as other general expenses.

As of September 30, 2023, Wave had $139.9 million in cash and cash equivalents, as compared to $88.5 million as of December 31, 2022. Subsequent to the quarter end, Wave received the $7.0 million for the achievement of the previously discussed milestone. The company expects that its current cash and cash equivalents will be sufficient to fund operations into 2025.
