CAMBRIDGE, Mass., August 3, 2023 — 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 second quarter ended June 30, 2023, and provided a business update.
“In the second quarter, we continued to rapidly advance our pipeline of RNA medicines towards meaningful inflection points. We are on the cusp of moving the industry’s first RNA editing therapeutic candidate, WVE-006 for alpha-1 antitrypsin deficiency or AATD, into the clinic, which will mark an important milestone not only for Wave, but also for individuals living with AATD and the entire RNA medicines field. WVE-006 has the potential to transform the standard of care for people living with AATD, and the goal of our initial clinical trial will be delivering early clinical proof-of-concept via measurement of validated serum surrogate markers,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. “While we were disappointed to discontinue WVE-004 for C9-ALS and FTD in the second quarter, we did see successful translation of our preclinical pharmacodynamic effects to clinical biomarker effects, including robust, sustained reductions of up to 50% in poly(GP) with multiple doses. These results are also important validation of our PN chemistry, which is encouraging for our current and upcoming clinical programs, including in DMD, HD, and AATD.”
Dr. Bolno continued: “Momentum is building rapidly in our collaboration with GSK, which kicked off at the start of this year, and we are actively working on multiple targets while leveraging proprietary genetic insights through the collaboration. We are excited to share new data on RNA editing disease targets at our annual ‘R&D Day’ virtual event in September. Wave is well-capitalized to leverage our unique, multimodal platform to develop novel RNA medicines and deliver on a steady cadence of clinical data through 2024 and beyond.”
Recent Business Highlights
| • | Presented new preclinical data for WVE-006 supporting its potential to be a first-and best-in-class treatment for alpha-1 antitrypsin deficiency (AATD). In May 2023, at the American Society of Gene & Cell Therapy (ASGCT) Annual Meeting, Wave presented data demonstrating that treatment with WVE-006 improved several markers of liver disease in mice, including a decrease in liver inflammation and hepatocyte turnover and reduction in the size of PAS-D positive globules. WVE-006 is uniquely designed to address both liver and lung disease related to AATD and is poised to be the industry’s first RNA editing candidate to reach the clinic. The company expects to submit clinical trial applications (CTAs) for WVE-006 imminently. |
| • | Highlighted clinical data for WVE-N531 to DMD community at Parent Project Muscular Dystrophy (PPMD) Annual Conference. In June 2023, in an oral presentation at the PPMD Conference, Wave highlighted its clinical data from the proof-of-concept study of WVE-N531, including the highest level of exon skipping seen in any DMD trial, high muscle concentrations, and a safe and tolerable profile. Wave is on track to initiate dosing in Part B, a potentially registrational Phase 2 trial of WVE-N531, in 2023, which will be powered to evaluate functional dystrophin expression following 24 and 48 weeks of biweekly dosing. The primary endpoint will be dystrophin protein levels, and the study will also evaluate safety and tolerability, pharmacokinetics, and functional endpoints. Data are expected in 2024. If successful, WVE-N531 has potential to become a near-term wholly owned commercial opportunity for Wave and would enable accelerated development of additional exon skipping candidates for other mutations. |
| • | Multi-dose portion of SELECT-HD study of WVE-003 for HD underway. In the second quarter, Wave initiated the multi-dose portion of its ongoing Phase 1b/2a SELECT-HD clinical trial of WVE-003 (allele-selective silencing oligonucleotide) for Huntington’s disease, and dosing is currently underway. |
| • | Emerging best-in-class siRNA designs highlighted at ASGCT. Also at the May 2023 ASGCT Annual Meeting, Wave highlighted its novel siRNA formats in a poster presentation titled “PN modification of stereopure GalNAc-siRNAs enhances durability of human HSD17B13 silencing in transgenic mouse model.” Wave’s GalNAc-siRNAs were more potent and had better durability of effect in mice compared with reference GalNAc-siRNA designs, which were driven by improved Ago2 loading. These data were also included in Wave’s Nucleic Acids Research publication from April 2023, which can be accessed here. |
| • | Wave Life Sciences added to Russell Indexes. In June 2023, the company joined the Russell 2000® and Russell 3000® Indexes as part of the annual reconstitution. |
Anticipated Upcoming Milestones and Events
WVE-N531 for DMD:
| • | Initiate dosing in Part B of potentially registrational Phase 2 clinical trial in 2023 |
| • | Deliver data from Part B in 2024 |
WVE-006 for AATD:
| • | Submit CTAs for first-in-human study in 2H 2023 |
WVE-003 for HD:
| • | Deliver additional single-dose and available multi-dose biomarker and safety clinical data in 2H 2023 |
Platform and Pipeline:
| • | “R&D Day” virtual event to be held on September 28, 2023, during which Wave will demonstrate how it is continuing to extend its leadership in RNA editing and share preclinical data on new wholly owned programs |
| • | Advance collaboration activities with GSK, with potential for additional cash inflows in 2023 and beyond |
Second Quarter 2023 Financial Results
Wave reported a net loss of $21.1 million in the second quarter of 2023, as compared to $41.3 million in the same period in 2022. The decrease in net loss year-over-year was primarily driven by revenue recognized under the company’s collaboration with GSK, which became effective January 27, 2023. Revenue recognized under the GSK and Takeda collaborations in the second quarter of 2023 was $22.1 million. During the second quarter of 2022, revenue of $0.4 million was recognized under the Takeda collaboration.
Research and development expenses were $33.3 million in the second quarter of 2023, as compared to $29.7 million in the same period in 2022. The increase in research and development expenses was primarily due to increased external expenses related to Wave’s clinical programs.
General and administrative expenses were $12.3 million in the second quarter of 2023, as compared to $12.8 million in the same period in 2022, primarily due to a decrease in share-based compensation.
As of June 30, 2023, Wave had $173.0 million in cash and cash equivalents, as compared to $88.5 million as of December 31, 2022. The company expects that its current cash and cash equivalents will be sufficient to fund operations into 2025.
Investor Conference Call and Webcast
Wave will host an investor conference call today at 8:30 a.m. ET to review second quarter 2023 financial results and pipeline updates. A webcast of the conference call can be accessed by visiting “Investor Events” on the investor relations section of the Wave Life Sciences website: https://ir.wavelifesciences.com/events-and-presentations.
