CAMBRIDGE, Mass., Nov. 09, 2020 (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 third quarter ended September 30, 2020 and provided a business update.
“The substantial progress made by Wave’s research and clinical teams during the third quarter has ushered in a new phase for the company, during which we are rapidly advancing several new programs incorporating our novel PN backbone chemistry modification. We are on track to file clinical trial applications for WVE-003 for Huntington’s disease and WVE-004 for amyotrophic lateral sclerosis and frontotemporal dementia this quarter. In addition, we are announcing today our plan to submit a clinical trial application in the first quarter of 2021 for a third PN backbone-containing molecule, WVE-N531 for patients with Duchenne muscular dystrophy who have mutations amenable to exon 53 skipping,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. “We are also excited to announce our first ADAR editing target, the SERPINA1 gene transcript, where a single base mutation is often the cause of alpha-1 antitrypsin deficiency. Using our unique ADAR editing capability to correct the RNA transcript, we will have the opportunity to address both liver and lung manifestations of the disease.”
“The 32 mg cohorts in the PRECISION-HD1 and PRECISION-HD2 Phase 1b/2a clinical trials continue to move ahead, and we look forward to sharing results from all cohorts, as well as initial data from the ongoing open-label extension trials, in the first quarter of 2021. We are well-positioned to progress our planned and existing programs with our current cash balance.”
Recent Business Highlights
PRECISION-HD programs for Huntington’s disease (HD): Wave is developing a unique portfolio of investigational stereopure oligonucleotides 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 lost one copy of the wtHTT allele, 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 is important for favorable health outcomes over a lifetime with the disease.
PRECISION-HD and OLE trials of WVE-120101 and WVE-120102:
- The PRECISION-HD1 and PRECISION-HD2 Phase 1b/2a clinical trials evaluating investigational WVE-120101 and WVE-120102, stereopure oligonucleotides designed to selectively target the mHTT mRNA transcript that contains SNP rs362307 (SNP1) and rs362331 (SNP2), respectively, in patients with HD are ongoing.
- Open-label extension (OLE) clinical trials for patients outside of the U.S. who participated in the Phase 1b/2a PRECISION-HD trials are also ongoing.
- In the first quarter of 2021, Wave expects to report data from all cohorts in both PRECISION-HD trials, including the 32 mg dose cohorts, as well as data from patients who received multiple doses of 8 or 16 mg of WVE-120101 or WVE-120102 in the OLE trials.
HD SNP3 program (WVE-003):
- Wave is developing a third allele-selective HD candidate, WVE-003, which is designed to selectively target an undisclosed SNP on the mHTT mRNA transcript (SNP3), while leaving wtHTT protein relatively intact. Between its SNP1, SNP2 and SNP3-targeted molecules, Wave has the potential to provide allele-selective options for up to 80% of people with HD.
- In preclinical studies, WVE-003 showed selective reduction of mHTT mRNA in vitro, and potent and durable knockdown of mHTT mRNA in vivo.
- WVE-003 incorporates Wave’s novel PN chemistry into its design.
- Wave expects to initiate clinical development of WVE-003 with the submission of a clinical trial application (CTA) in the fourth quarter of 2020.
C9orf72 program (WVE-004) for amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD): WVE-004 is designed to selectively target the transcript variants containing the hexanucleotide repeat expansion (G4C2) in the C9orf72 gene. G4C2 expansions in the C9orf72 gene lead to reduced expression of healthy protein, accumulation of repeat-containing transcripts and RNA binding proteins into nuclear RNA foci, and aberrant expression of neurotoxic dipeptide repeat proteins (DPRs).
- In preclinical studies in transgenic mice following two intracerebroventricular administered doses, WVE-004 showed potent and durable knockdown of repeat-containing transcripts and DPRs while sparing healthy C9orf72 protein over a period of six months.
- WVE-004 incorporates Wave’s novel PN chemistry into its design.
- Wave expects to initiate clinical development of WVE-004 with the submission of a CTA in the fourth quarter of 2020.
Exon 53 program (WVE-N531) for Duchenne muscular dystrophy (DMD): Based on compelling in vitro and in vivo preclinical results from compounds incorporating Wave’s novel PN chemistry, Wave is advancing WVE-N531 to explore splicing in dystrophic muscle. Planning is underway for a clinical trial to assess dystrophin production and initial safety in patients with DMD amenable to exon 53 skipping.
- WVE-N531 induced a dose-dependent increase in dystrophin production (up to 71%) in vitro in DMD patient-derived myoblasts.
- In an ongoing in vivo study of double knock-out mice (a model lacking dystrophin and utrophin protein with a severe phenotype), an oligonucleotide with PN backbone chemistry modifications appeared to significantly increase dystrophin production and substantially improve muscle function and survival.
- WVE-N531 incorporates Wave’s novel PN chemistry into its design.
- Wave expects to submit a CTA for WVE-N531 in the first quarter of 2021.
SERPINA1 program for alpha-1 antitrypsin deficiency (AATD) with ADAR-mediated RNA editing (ADAR editing): Wave announced today that it is applying its ADAR editing platform capability to develop a potential novel treatment for AATD aimed at addressing the lung and liver manifestations of the disease.
- AATD is a rare, inherited genetic disorder that is commonly caused by a single G-to-A point mutation in the SERPINA1 gene, called the SERPINA1 Z allele. This mutation leads to misfolding and aggregation of alpha-1 antitrypsin (AAT) protein in hepatocytes and a lack of functional AAT in the lungs. People with AATD typically exhibit progressive lung damage, liver damage or both, leading to frequent hospitalizations and potentially terminal lung disease and/or liver disease. The few approved therapies for AATD modestly increase circulating levels of AAT in those with the lung pathology; there are no approved therapies to address the liver pathology. Approximately 250,000 people worldwide are homozygous for the Z allele, which is the most severe form of the disease.
- Wave’s novel RNA editing platform capability uses endogenous ADAR (adenosine deaminases acting on RNA) enzymes via free uptake (non-viral, no nanoparticles) of A-to-I (G) RNA editing oligonucleotides, making this a potentially best-in-class modality for correcting the G-to-A disease-causing mutation in mRNA coded by the SERPINA1 Z allele.
- By correcting the single RNA base mutation, ADAR editing may provide an ideal approach for increasing circulating levels of wild-type AAT protein and reducing aggregation in the liver, thus simultaneously addressing both the lung and liver manifestations of the disease.
- In a primary hepatocyte SERPINA1 Z cell model, editing the Z transcript back to wild-type prevented protein misfolding and increased secretion from hepatocytes.
- Wave is developing a proprietary in vivo model system, which uses human ADAR and human target transcript, to support the ongoing development of its ADAR editing platform. Data from its humanized SERPINA1/ADAR model are expected in the first half of 2021.
- Wave’s SERPINA1 program and ADAR editing platform capability incorporate the company’s novel PN chemistry.
Central nervous system (CNS) programs in collaboration with Takeda: Wave is leveraging learnings from PRISMTM, the company’s propriety discovery and drug development platform, to design additional stereopure oligonucleotides with optimized profiles for CNS indications, including in Alzheimer’s disease, Parkinson’s disease and others, as part of its ongoing collaboration with Takeda.
- Wave is utilizing PN backbone chemistry modifications to produce compelling in vivo data and actively progress up to six preclinical targets.
- In an in vivo study in non-human primates (NHPs) for the most advanced therapeutic program in the collaboration, approximately 90% knockdown of the target mRNA was observed one month after a single 12 mg intrathecal dose. The therapeutic candidate distributed widely across multiple relevant CNS tissues.
Novel PN chemistry announced at Analyst & Investor Research Webcast: On August 25, 2020, Wave held an Analyst and Investor Research Webcast to highlight recent advancements to PRISM, including the expansion of its repertoire of backbone modifications with the introduction of PN backbone chemistry.
- PN chemistry is a backbone modification that involves replacing a non-bridging Oxygen atom with a Nitrogen-containing moiety.
- In preclinical experiments, judicious use of PN backbone chemistry modifications in stereopure oligonucleotides have generally increased potency, exposure and durability across Wave’s silencing, splicing and editing modalities.
- Wave’s current preclinical and discovery-stage programs incorporate PN backbone chemistry modifications.
Third Quarter 2020 Financial Results and Financial Guidance
As of September 30, 2020, Wave had $216.4 million in cash and cash equivalents as compared to $147.2 million as of December 31, 2019. During the third quarter of 2020, Wave substantially extended its cash runway by raising $93.7 million in net proceeds from its September 2020 public offering and $48 million in net proceeds from its at-the-market equity program, and receiving $16.8 million in refundable tax credits.
Wave reported a net loss of $33.1 million in the third quarter of 2020 as compared to $50.7 million in the same period in 2019.
Research and development expenses were $28.3 million in the third quarter of 2020 as compared to $44.6 million in the same period in 2019. The decrease in research and development expenses in the third quarter was primarily due to decreased external expenses related to suvodirsen, due to Wave’s December 2019 decision to discontinue the program, as well as decreased headcount and other external expenses driven by Wave's February 2020 cost reduction plan, partially offset by increased 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 $9.6 million in the third quarter of 2020 as compared to $12.5 million in the same period in 2019. The decrease in general and administrative expenses in the third quarter of 2020 was primarily due to the February 2020 cost reduction plan, which included a workforce reduction.
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.
