Candidate selected by GSK utilizes Wave’s best-in-class SpiNA design siRNA and triggers a milestone payment to Wave; three additional collaboration programs advancing

CAMBRIDGE, Mass., Sept. 30, 2026 (GLOBE NEWSWIRE) -- Wave Life Sciences, Inc. (Nasdaq: WVE), a clinical-stage biotechnology company focused on unlocking the broad potential of RNA medicines to transform human health, today announced that as part of the companies’ research collaboration, GSK has selected a candidate for a hepatology indication to transition into GSK’s development pipeline. This program was developed using Wave’s proprietary SpiNA design GalNAc-siRNA.

“The advancement of this development candidate by GSK reflects the recognition of Wave’s differentiated technology, including our best-in-class SpiNA design siRNA,” said Paul Bolno, MD, MBA. “Our SpiNA siRNA compounds demonstrate superior pharmacology, including improved potency, durability and Ago2 loading versus comparator formats. Our collaboration with GSK continues to leverage the versatility of our PRISM™ platform coupled with human genetic insights to advance novel oligonucleotide therapeutics. With this new hepatic program now transitioning to candidate, our collaboration momentum continues as we have three additional programs rapidly advancing towards candidate selection, all leveraging our proprietary PRISM chemistry.”

Wave will receive a $12 million milestone payment for this candidate selection. In addition, Wave is eligible to receive up to $330 - $375 million in development, launch, and commercial milestones for each collaboration program, plus tiered royalties on net sales. Wave is currently advancing three additional collaboration programs towards potential candidate selection.
