Achieving the first-ever therapeutic RNA editing in humans is a significant milestone for our
organization, for our GSK collaboration, and for the entire oligonucleotide field. It also unlocks and derisks Waves RNA editing platform, in light of the continued strong clinical translation of our proprietary
best-in-class chemistry, including PN, stereochemistry and our N3U AIMer modification, said Paul Bolno, MD, MBA, President and Chief Executive Officer
at Wave Life Sciences. The level of mRNA editing we are observing with a single dose exceeded our expectations and we expect M-AAT levels to continue to increase with repeat dosing, based on our
preclinical data. These initial data, alongside WVE-006s durability and convenient subcutaneous administration, are all supportive of a
best-in-class profile for WVE-006 relative to other editors and in the broader AATD space. These data also increase our
confidence in our wholly owned pipeline, including our HD, DMD and obesity programs, as well as our next RNA editing targets. We look forward to introducing the next RNA editing programs, as well as providing an update on our INHBE GalNAc-siRNA
program in obesity, at our Research Day on October 30.
There are an estimated 200,000 individuals living with AATD in the US and Europe who are
homozygous for the SERPINA1 Z mutation. Treatment options are currently limited to weekly IV augmentation therapy for lung disease only (representing over $1.4 billion in worldwide sales in 2023). There are no approved therapies to address AATD
liver disease, which ultimately requires many individuals living with AATD to undergo liver transplantation.
GSK has the exclusive global license for WVE-006. Development and commercialization responsibilities will transfer to GSK after Wave completes the RestorAATion-2 study. In total, Wave is eligible for up to
$525 million in milestones, as well as tiered royalties on net sales, for WVE-006.
