CAMBRIDGE, Mass., March 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 financial results for the fourth quarter and full year ended December 31, 2021 and provided a business update.

“Wave achieved multiple significant milestones in 2021, including successfully bringing PN chemistry into the clinic with the initiation of three new clinical trials with our next-generation RNA silencing and exon-skipping therapeutics, as well as demonstrating the first successful protein restoration with AIMers in preclinical in vivo models for the treatment of alpha-1 antitrypsin deficiency, also known as AATD. These accomplishments have positioned us to deliver several key datasets in 2022 to inform the potential of our novel oligonucleotides across tissues and modalities,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences.

“We continue to rapidly advance our AIMer RNA editing capabilities and are poised to deliver a first-in-class novel modality to address both lung and liver manifestations of AATD. We remain on track to select our first GalNAc-AIMer development candidate in the third quarter of this year, and we are leading the way with RNA base editing to address a wide array of genetic diseases, with potentially even more expansive applications through protein modulation. Lastly, our decade of investment in our PRISM platform has resulted in a robust and diverse pipeline, as well as internal GMP manufacturing capabilities that can be scaled to support our needs as well as potential new partners,” continued Dr. Bolno.

Recent Business Highlights and Upcoming Milestones

Clinical silencing and exon skipping therapeutic programs:

Scientific publications:

In February 2022, Wave announced two publications in the journal Nucleic Acids Research (NAR) supporting the incorporation of PN backbone chemistry modifications (PN chemistry) in stereopure oligonucleotides as a significant advancement for the therapeutic oligonucleotide field. In the multitude of in vitro and in vivo (animal) studies highlighted in Wave’s papers, PN chemistry was shown to dramatically improve potency, distribution, and durability of effect. The papers explore the use of PN chemistry in stereopure silencing oligonucleotides (publication link) for central nervous system (CNS) diseases – designated as a Breakthrough Article by NAR — and stereopure splicing oligonucleotides (publication link) for neuromuscular diseases.

WVE-N531 for Duchenne muscular dystrophy (DMD) amenable to exon 53 skipping:

WVE-N531 (PN-modified splicing oligonucleotide) is being evaluated in an open-label, intra-patient dose escalation clinical trial. Dose escalation is ongoing and being guided by tolerability and plasma PK, with possible cohort expansion informed by an assessment of drug distribution in muscle and biomarkers, including dystrophin, following multiple doses of WVE-N531.When comparing PN-modified compounds, including WVE-N531, to first-generation PS/PO (non-PN-modified) compounds, PN chemistry consistently leads to increased exon-skipping activity, increases in muscle exposure, longer half-life, and more durable effects in preclinical mouse and non-human primate studies. Based on an analysis of initial plasma PK from the starting single dose of WVE-N531 in Wave’s ongoing clinical trial, there was a substantial increase in plasma concentrations and a clear increase in plasma half-life as compared to suvodirsen, Wave’s first-generation PS/PO exon-skipping compound.

WVE-004 for C9orf72-associated amyotrophic lateral sclerosis (C9-ALS) and frontotemporal dementia (C9-FTD):

FOCUS-C9 is an ongoing, double-blind, adaptive, Phase 1b/2a clinical trial of WVE-004. WVE-004 is an investigational stereopure PN-modified silencing oligonucleotide designed to selectively target transcript variants containing a hexanucleotide repeat expansion (G4C2) associated with the C9orf72 gene for the treatment of C9-ALS and C9-FTD.In January 2022, the Alzheimer’s Drug Discovery Foundation (ADDF) and The Association for Frontotemporal Degeneration (AFTD) announced they had partnered to support Wave’s FOCUS-C9 clinical trial, specifically the evaluation of fluid biomarkers, functional assessments, and digital biomarkers used in the study, potentially leading to clinically meaningful endpoints to inform drug development for FTD. The decision to support the FOCUS-C9 trial was made following a review by members of the Treat FTD Fund Joint Steering Committee of Wave’s Phase 1b/2a study plan, preclinical data supporting the program and expertise of the study team.

WVE-003 targeting SNP3 for Huntington’s disease (HD):

SELECT-HD is an ongoing, double-blind, adaptive, Phase 1b/2a clinical trial of WVE-003. WVE-003 is an investigational stereopure PN-modified silencing oligonucleotide designed to selectively target the mutant allele of the huntingtin (mHTT) gene, while leaving the wild-type (healthy) HTT (wtHTT) protein relatively intact.In March 2022, Wave presented at the CHDI Foundation’s 17th Annual HD Therapeutics Conference, including a poster titled “A novel quantitative wild-type huntingtin (wtHTT) protein biomarker method for human cerebrospinal fluid” that highlights Wave’s wtHTT assay, which is intended to assess preservation of wtHTT protein in CSF in the setting of mHTT targeting, including in the ongoing SELECT-HD clinical trial.

Upcoming clinical milestones:

Wave expects to share clinical data in 2022 for WVE-004, WVE-003, and WVE-N531 to provide insight into the clinical effects of PN chemistry and enable decision-making for each program.

ADAR editing therapeutic programs (RNA editing using endogenous ADAR enzymes)

Scientific presentations:

In January 2022, Wave gave an oral presentation titled “Towards the development of a therapeutic RNA editing platform” at the 3rd International Conference on Base Editing – Enzymes and Applications Deaminet 2022, which highlighted Wave’s RNA editing platform, the ability of AIMers to restore expression of functional protein in preclinical models in vivo and modulate protein-protein interactions in vitro.Wave leadership will present at the upcoming 3rd RNA Editing Summit on April 5 – 7, 2022 in Boston.

AATD program updates and upcoming milestones:

Wave today announced new preclinical data demonstrating restoration of functional AAT protein in a transgenic mouse model with GalNAc-conjugated SERPINA1 AIMers. At 19 weeks, AIMer treatment resulted in approximately 60% RNA editing of SERPINA1 transcript and circulating serum AAT levels (18.5 uM) in AIMer treated mice that were approximately 5-fold greater than PBS-treated controls.Today, Wave also shared a histological analysis that indicates reduction of liver aggregates in a transgenic mouse model at 19 weeks with AIMer treatment.In November 2021, Wave presented a poster at AASLD: The Liver Meeting, that included data demonstrating SERPINA1 AIMers achieve highly specific RNA editing in vivo, resulting in wild-type, M-AAT protein circulating in serum that was functional in a neutrophil elastase inhibition assay.Wave expects to select an AATD AIMer development candidate and initiate IND-enabling toxicology studies in the third quarter of 2022.

Fourth Quarter and Full Year 2021 Financial Results and Financial Guidance

Wave reported a net loss of $34.8 million in the fourth quarter of 2021, as compared to $28.8 million in the same period in 2020. Wave reported a net loss of $122.2 million for the year ended December 31, 2021, as compared to $149.9 million for the year ended December 31, 2020.

Revenue earned under the Takeda Collaboration in the fourth quarter of 2021 was $1.8 million, as compared to $9.4 million for the same period in 2020. The decrease in revenue year-over-year is mainly due to the amendment of Wave’s collaboration with Takeda, which discontinued the Category 2 discovery research component of the Takeda Collaboration in exchange for an additional $22.5 million, which Wave received in October 2021 and accounted for in the third quarter of 2021. The Category 1 late-stage component of the Takeda Collaboration remains in effect and was unchanged by the amendment. During the year ended December 31, 2021, Wave earned $41.0 million under the Takeda Collaboration, as compared to $20.1 million earned under the Takeda Collaboration and the Pfizer Collaboration during the year ended December 31, 2020. The year-over-year increase is primarily driven by recognition of revenue related to the $22.5 million related to the Takeda Amendment.

Research and development expenses were $25.8 million in the fourth quarter of 2021 as compared to $30.0 million in the same period in 2020. Research and development expenses were $121.9 million in 2021, as compared to $130.9 million in 2020. The decrease in research and development expenses in the fourth quarter and full year was primarily due to decreased external expenses related to our previously disclosed discontinued PRECISION-HD programs, partially offset by increased internal and external expenses related to WVE-004, PRISM, including ADAR editing, and other ongoing programs.

General and administrative expenses were $12.1 million in the fourth quarter of 2021 as compared to $9.7 million in the same period in 2020. General and administrative expenses were $46.1 million in 2021, as compared to $42.5 million in 2020. The increase in general and administrative expenses in the fourth quarter of 2021 and full year was driven by increases in compensation-related and other external general and administrative expenses.

As of December 31, 2021, Wave had $150.6 million in cash and cash equivalents as compared to $184.5 million as of December 31, 2020. The decrease in cash and cash equivalents was mainly due to Wave’s year-to-date net loss of $122.2 million, partially offset by the receipt of $54.9 million in net proceeds under Wave’s ATM equity program and funds of $52.5 million received from our collaboration with Takeda.

Wave expects that its existing cash and cash equivalents will enable the company to fund its operating and capital expenditure requirements into the second quarter of 2023.
