Wave to host investor conference call and webcast at 8:30 a.m. ET today
CAMBRIDGE, Mass., May 11, 2020 – 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, 2020 and provided a business update.
“During the last few months, our team has done a tremendous job of navigating the realities of the global COVID-19 pandemic, while making substantial progress on our critical priorities, including delivering on a key 2020 milestone, our initial in vivo RNA-editing dataset. We are working tirelessly to keep our clinical trials ongoing, our preclinical programs moving towards clinical development, and our discovery work on track, all while supporting each other and our communities during this difficult time,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences.
“Our PRECISION-HD clinical trials of WVE-120101 and WVE-120102, two investigational compounds designed to selectively target mutant HTT for the treatment of Huntington’s disease, are ongoing. While the pandemic has impacted several global clinical trial sites, the commitment of our patients and investigators remains resolute, speaking to the high unmet need for disease modifying therapeutics for this devastating disease. In addition, we currently remain on track to initiate clinical development for two additional neurological programs in the second half of 2020. Lastly, today we are announcing new data from our ADAR-mediated RNA-editing program and I look forward to sharing further updates on this emerging platform capability later this year.”
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) relatively intact.
PRECISION-HD2:
| • | The PRECISION-HD2 Phase 1b/2a clinical trial, Wave’s clinical trial investigating WVE-120102, a stereopure oligonucleotide designed to selectively target the mHTT mRNA transcript that contains the SNP rs362331 (SNP2) for HD, is ongoing. |
| • | Data from the 32 milligram (mg) dose cohort of the PRECISION-HD2 trial are currently expected in the second half of 2020. |
1
| • | An open-label extension (OLE) study open to patients outside of the U.S. who participated in the Phase 1b/2a PRECISION-HD2 trial is ongoing. |
PRECISION-HD1:
| • | In March 2020, Wave initiated a 32 mg dose cohort in the ongoing PRECISION-HD1 Phase 1b/2a clinical trial of WVE-120101, a stereopure oligonucleotide designed to selectively target the mHTT mRNA transcript that contains the SNP rs362307 (SNP1) for HD. |
| • | Wave currently expects to deliver topline clinical data from the PRECISION-HD1 trial, including the 32 mg dose cohort, in the second half of 2020. |
| • | An open-label extension (OLE) study open to patients outside of the U.S. who participated in the Phase 1b/2a PRECISION-HD1 trial is ongoing. |
PRECISION-HD trials:
| • | Wave continues to work closely with the PRECISION-HD clinical trial sites to monitor the impact of the evolving COVID-19 pandemic. If global restrictions continue or worsen, the ability to evaluate patients in both of the PRECISION-HD trials as planned may be impacted. |
| • | Wave is assessing the potential for a next higher dose cohort to be added to both PRECISION-HD trials. |
SNP3 program for HD: Wave is advancing a third HD program, which is designed to selectively target an undisclosed SNP on the mHTT mRNA transcript (SNP3), while leaving the wild-type (wtHTT) relatively intact.
| • | Wave expects to initiate clinical development of its SNP3 program in the second half of 2020. |
C9orf72 program for ALS and FTD: Wave’s C9orf72 program is designed to selectively target the transcripts containing the hexanucleotide repeat expansion (G4C2) in the C9orf72 gene.
| • | Wave is advancing its C9orf72 preclinical program to potentially treat amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) and expects to initiate clinical development in the second half of 2020. |
Central nervous system (CNS) programs in collaboration with Takeda: Wave is leveraging its learnings from PRISM™ to design additional stereopure oligonucleotides with optimized profiles for CNS indications, including Parkinson’s, Alzheimer’s and others, as part of its ongoing collaboration with Takeda.
| • | In the first quarter, Wave achieved target validation in vivo with a lead compound for a second program and expects to achieve target validation for a third program in 2020. |
RNA editing: Wave is designing a novel RNA-editing platform capability using endogenous ADAR (adenosine deaminases acting on RNA) enzymes via free uptake (non-viral, non-LNP) of RNA-editing oligonucleotides, which has the potential to be a best-in-class RNA-editing modality.
| • | Today, Wave announced it has achieved successful RNA editing of ACTB (Beta-actin) mRNA in non-human primates (NHPs) via endogenous ADARs using stereopure GalNAc-conjugated oligonucleotides. In an ongoing proof-of-concept study, Wave oligonucleotides demonstrated up to 50% A to I (G) editing of ACTB mRNA in the liver of NHPs two-days post-last dose. To the company’s knowledge, these are the first publicly available data that demonstrate successful RNA editing in vivo in NHPs. |
| • | This RNA-editing platform is expected to be applicable for a wide range of disease targets. Wave has previously shown that its RNA-editing oligonucleotides achieved editing across multiple distinct transcripts in primary human hepatocytes and this in vitro data will also be presented at the upcoming American Society of Gene & Cell Therapy (ASGCT) Annual Meeting, being held virtually May 12 – May 15. |
| • | Wave expects to share additional in vivo ADAR-mediated RNA-editing data and to announce its first RNA-editing program in 2020. |
First Quarter 2020 Financial Results and Financial Guidance
Wave reported a net loss of $47.5 million in the first quarter of 2020 as compared to $44.2 million in the same period in 2019.
2
Research and development expenses were $41.2 million in the first quarter of 2020 as compared to $40.1 million in the same period in 2019. The increase in research and development expenses in the first quarter was primarily due to increased external expenses related to our clinical and preclinical activities, including our HD programs and C9orf72 program for ALS and FTD, and separation costs associated with the workforce reduction implemented in February 2020, partially offset by decreased external expenses related to our DMD programs due to our December 2019 decision to discontinue the suvodirsen program and to cease development of our other DMD programs.
General and administrative expenses were $13.0 million in the first quarter of 2020 as compared to $10.9 million in the same period in 2019. The increase in general and administrative expenses in the first quarter of 2020 was mainly driven by separation costs associated with the workforce reduction implemented in February 2020.
As of March 31, 2020, Wave had $120.9 million in cash and cash equivalents as compared to $147.2 million as of December 31, 2019. The decrease in cash and cash equivalents was mainly due to Wave’s year-to-date net loss of $47.5 million, partially offset by the receipt of $20 million in research support funding from Takeda under our collaboration.
Wave expects that its existing cash and cash equivalents, together with expected and committed cash from its existing collaboration, will enable Wave to fund its operating and capital expenditure requirements into the third quarter of 2021.

Evidence suggests wild-type or healthy HTT is neuroprotective in an adult brain Transport of key neurotrophic factors such as brain-derived neurotrophic factor (BDNF) are regulated by wtHTT levels Relative proportion of wild-type to mutant protein is critical Increased amount of wild-type protein relative to mutant HTT may result in slower disease progression (measured by age-at-onset) Patients with lack of wild-type have significantly more severe disease (measured by disease progression after symptom onset) Importance of wild-type huntingtin (wtHTT) in HD Neuro HD Huntington’s disease (HD) may be caused by a dominant gain of function in mutant HTT and a loss of function of wtHTT protein Sources: Van Raamsdonk, J.M., et al., Hum Mol Genet, 2005; Van Raamsdonk, J.M., et al., BMC Neurosci, 2006; Becanovic, K., et al., Nat Neurosci, 2015; Saudou, F. and S.

Recent publication contributes to weight of evidence on importance of wild-type huntingtin Poplawski et al., Nature, April 2019; Htt: Huntingtin protein Conditional knock-out of Htt in 4-month old mice (post-neuronal development) Results suggest that: Htt plays a central role in the regenerating transcriptome (potentially influencing genes such as NFKB, STAT3, BDNF) Htt is essential for regeneration Indeed, conditional gene deletion showed that Htt is required for neuronal repair. Throughout life, neuronal maintenance and repair are essential to support adequate cellular functioning Neuro HD
Increasing evidence on the importance of wtHTT in HD pathogenesis, CNS and systemic health Striatum-specific defect in synaptic vesicle endocytosis that was not corrected by total lowering of HTT Corrected by overexpression of wild-type protein Striatal projection neurons require HTT for motor regulation, synaptic development, cell health, and survival during aging Loss of HTT function could play a critical role in HD pathogenesis wtHTT in HD highlighted at CHDI 15th Annual HD Therapeutics Conference: HTT LOWERING: EXPLORING DISTRIBUTION, TIMING, AND SAFETY (LOSS OF FUNCTION) Key points discussed at meeting: wtHTT has numerous critical functions throughout life (e.g., intracellular trafficking, cell-cell adhesion, BDNF transport) Near elimination of mouse wtHtt detrimental regardless of when suppression begins Specific brain regions, e.g., STN, may be particularly vulnerable to wtHTT lowering Mouse Htt lowering can lead to thalamic, hepatic, pancreatic toxicity HTT LoF mutations highly constrained in human population, suggesting selection against LoF mutations Recent publications on wtHTT LoF as a likely driver of HD pathogenesis LoF: Loss of function; wtHTT: wild-type huntingtin; HD: Huntington’s disease; STN: subthalamic nucleus Neuro HD
