Wave Life Sciences Reports Second Quarter 2024 Financial Results and Provides Business Update
Successful clinical translation of Wave’s RNA medicines platform in HD patients with WVE-003 provides further validation of Wave’s proprietary platform with PN and stereochemistry; opt-in package for WVE-003 submitted to partner Takeda and engagement with regulators initiated to discuss potential path to accelerated approval
Dystrophin data on track for 3Q 2024 from potentially registrational FORWARD-53 trial of WVE-N531, which has previously demonstrated industry-leading exon skipping of 53%; positive data would unlock a best-in-class functional dystrophin franchise for DMD
Dosing initiated in 3Q 2024 in RestorAATion-2 clinical trial of WVE-006 in AATD patients; proof-of-mechanism data in AATD patients expected in 4Q 2024
New preclinical data supporting INHBE siRNA (WVE-007) as a potential best-in-class treatment for obesity, as well as new data from Wave’s wholly owned pipeline of RNA medicines, expected at R&D Day in Fall 2024

CAMBRIDGE, Mass., August 8, 2024 – Wave Life Sciences Ltd. (Nasdaq: WVE), a clinical-stage biotechnology company focused on unlocking the broad potential of RNA medicines to transform human health, today announced financial results for the second quarter ended June 30, 2024, and provided a business update.
“With our recent positive SELECT-HD trial results, we have further validated our chemistry and the clinical translation of our platform. Today, we have built an RNA medicines platform that is positioned to sustainably translate clinical genetic insights into transformational medicines as we continue to advance our lead programs through multiple important milestones in the second half of this year,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. “Clinical results from our SELECT-HD trial in HD demonstrated statistically significant, potent, and durable allele-selective silencing with WVE-003, and we are working rapidly to engage regulators on a potential path to accelerated approval. These data have also bolstered our confidence ahead of expected upcoming readouts from our potentially registrational FORWARD-53 trial in DMD and our RestorAATion-2 trial in AATD. In parallel with these efforts, we continue to drive our best-in-class obesity candidate, WVE-007, toward the clinic and are on track to initiate the first-in-human study in the first quarter of next year. We look forward to providing additional updates on our growing, high-value pipeline and our progress towards reimagining what’s possible for human health at our R&D Day this Fall.”
