Wave Life Sciences Reports First Quarter 2021 Financial Results and Provides Business Update

CAMBRIDGE, Mass., May 13, 2021 (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 first quarter ended March 31, 2021 and provided a business update.

“Despite our PRECISION-HD results at the end of the first quarter, it has been a productive start of the year for Wave and our team remains focused on advancing our clinical trials for ALS/FTD, HD and DMD. These new trials mark the transition of our next-generation programs into the clinic. We expect clinical data that will provide insight into PN chemistry and enable decision making on next steps for these programs next year,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. “We have a deep and diverse pipeline of RNA therapeutics, each designed with our PN chemistry, which has been shown to increase potency, exposure and durability compared to our first-generation compounds in preclinical studies. We continue to produce compelling in vivo data, and we are advancing multiple programs for CNS indications, including Alzheimer’s disease, Parkinson’s disease and others, in collaboration with our partner Takeda. Our ADAR editing capability demonstrates the diversity of our genetic medicines toolkit and we are well-positioned to be leaders in the RNA editing field. We look forward to providing more updates on ADAR editing, including the first in vivo data from our AATD program, in the first half of this year.”

Recent Business Highlights and Upcoming Milestones

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

  • WVE-004 is an investigational antisense oligonucleotide designed to selectively target transcript variants containing a hexanucleotide repeat expansion (G4C2) in the C9orf72 gene, which is one of the most common genetic causes of the sporadic and inherited forms of ALS and FTD. WVE-004 uses novel PN backbone chemistry modifications.
  • In February 2021, Wave published in Nature Communications the results of initial work to identify and validate its targeting strategy to achieve variant-selective knockdown of expansion-containing C9orf72 transcripts.
  • In April 2021, during a platform presentation at the American Academy of Neurology (AAN) 2021 Virtual Annual Meeting, Wave highlighted preclinical in vivo data for WVE-004, which demonstrated potent and durable knockdown of more than 90% of polyGP dipeptide repeat (DPR) proteins in the spinal cord and at least 80% in the cortex, an effect that persisted for at least six months. C9orf72 protein was relatively unchanged over the same time period.
  • This week, at the European Network to Cure ALS (ENCALS) meeting being held May 12 – May 14, Wave is presenting a poster introducing its FOCUS-C9 Phase 1b/2a trial design for WVE-004. The FOCUS-C9 trial is a global, multicenter, randomized, double-blind, placebo-controlled Phase 1b/2a clinical trial to assess the safety and tolerability of intrathecal doses of WVE-004 for patients with C9-ALS and/or C9-FTD. Additional objectives include measurement of polyGP proteins in the cerebrospinal fluid (CSF), plasma and CSF pharmacokinetics, and exploratory biomarker and clinical endpoints. The FOCUS-C9 trial is designed to be adaptive and includes single- and multiple-ascending dose portions, with dose escalation and dosing frequency being guided by an independent safety committee.
  • Wave has received regulatory and ethics approvals and site activation is underway for the FOCUS-C9 clinical trial, and Wave expects to initiate dosing in 2021.

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

  • WVE-003 is Wave’s next-generation HD candidate and Wave’s first HD candidate that uses PN chemistry. WVE-003 is designed to selectively target the mutant allele of the huntingtin (mHTT) gene, while leaving the wild-type (wtHTT) protein relatively intact. Wave’s approach to HD is guided by the recognition that, in addition to a gain of function of the mHTT protein, people with this disease have less wtHTT protein, leaving them with a smaller protective reservoir of healthy protein than unaffected individuals. A growing body of scientific evidence suggests that preserving as much of this essential protein as possible, when in the setting of stress from toxic mHTT protein, may be important for favorable clinical outcomes.
  • In April 2021, at the 16th Annual CHDI Foundation Huntington’s Disease Therapeutic Conference, Wave highlighted preclinical data for WVE-003, which showed selective reduction of mHTT mRNA in vitro and potent and durable knockdown of mHTT mRNA in vivo. Wave also introduced the design for the Phase 1b/2a clinical trial of WVE-003, called SELECT-HD. The multicenter, randomized, double-blind, placebo-controlled trial will assess the safety and tolerability of intrathecally administered WVE-003 for patients with early manifest Huntington’s disease. Additional objectives include measurement of mHTT and wtHTT protein and exploratory pharmacokinetic, pharmacodynamic, clinical and MRI endpoints. The trial is designed to be adaptive, with dose escalation and dosing frequency being guided by an independent safety committee.
  • Wave has received regulatory and ethics approvals and site activation is underway for the SELECT-HD clinical trial, and Wave expects to initiate dosing in 2021.

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

  • WVE-N531 is Wave’s first splicing candidate to incorporate PN chemistry, which Wave advanced following results of an in vivo study in double knock-out mice (dKO) that showed that an oligonucleotide designed with PN chemistry appeared to significantly increase dystrophin production and substantially improve survival, compared to oligonucleotides designed with Wave’s first-generation chemistry.
  • In March 2021, Wave initiated clinical development of WVE-N531 with the submission of a clinical trial application.
  • Wave has received regulatory approval for a clinical trial of WVE-N531 to assess initial safety and dystrophin production in patients with DMD amenable to exon 53 skipping. Wave expects to initiate dosing in this trial in 2021.

ADAR editing:

  • In March 2021, Wave presented a poster at the 2021 Keystone eSymposia on Precision Engineering of the Genome, Epigenome and Transcriptome highlighting the breadth of RNA editing data generated using its ADAR editing capability to date. This presentation illustrated editing activity across in vivo and in vitro systems, including in vivo editing in the CNS, using conjugated and non-conjugated oligonucleotides. Wave will also present these data in an oral presentation at the 24th American Society of Gene and Cell Therapy (ASGCT) Annual Meeting being held this week, May 11 – 14, 2021.
  • Wave expects to present additional ADAR editing data at scientific congresses in 2021.

Alpha-1 antitrypsin deficiency (AATD) program with ADAR editing:

  • Wave’s AATD program, its first ADAR editing program, uses an oligonucleotide to correct the single RNA base mutation in mRNA coded by the SERPINA1 Z allele. ADAR editing may provide an ideal approach to treating AATD by increasing circulating levels of healthy alpha-1 antitrypsin (AAT) protein and reducing aggregation in the liver, thus simultaneously addressing both the lung and liver manifestations of the disease.
  • To support the continued development of its AATD program, Wave has developed a proprietary humanized SERPINA1/ADAR model. Wave expects to share in vivo data from this model in the first half of 2021 and plans to submit these data for presentation at a scientific congress in 2021.

First Quarter 2021 Financial Results and Financial Guidance
Wave reported a net loss of $42.5 million in the first quarter of 2021 as compared to $47.5 million in the same period in 2020.

Research and development expenses were $33.4 million in the first quarter of 2021 as compared to $41.2 million in the same period in 2020. The year-over-year decrease was primarily due to the decrease in external expenses related to Wave’s suvodirsen program, which was discontinued in December 2019, but had wind-down costs throughout 2020, as well as decreases in compensation-related expenses and other external expenses, partially offset by the increases in external expenses related to Wave’s clinical and preclinical activities related to its HD programs and its C9orf72 program for ALS and FTD.

General and administrative expenses were $10.1 million in the first quarter of 2021, as compared to $13.0 million in the same period in 2020. The year-over-year decrease was driven by decreases in compensation-related expenses and other external expenses.

Wave ended the first quarter of 2021 with $148.5 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, partially offset by the receipt of $8.0 million in net proceeds under Wave’s at-the-market equity program. In April 2021, Wave received an additional $30.0 million in committed research support under its collaboration with Takeda.

Wave expects that its existing cash and cash equivalents, together with expected and committed cash from its existing collaboration, will enable the company to fund its operating and capital expenditure requirements into the second quarter of 2023.
