selective, potent, and durable reduction of mHTT in preclinical models Selectively reduces mHTT mRNA in HD iPSC neurons in vitro Results from ND50036 iPSC-derived medium spiny neurons. Total HTT knockdown quantified by qPCR and normalized to
HPRT1. Oligonucleotide or PBS [100 μg ICV injections through cannula on days 1, 3, 5] delivered to BACHD transgenic. Mean ± SD (n=8, *P<0.0332, ***P<0.0002, ****P<0.0001 versus PBS unless otherwise noted). HPRT1,
hypoxanthine-guanine phosphoribosyl transferase; iPSC, induced pluripotent stem cell; ICV, intracerebroventricular; PBS, phosphate-buffered saline Similar results in cortex Pan-silencing reference compound WVE-003 PBS Weeks *** ****
**** **** **** **** Pan-silencing reference compound WVE-003 Percentage HTT mRNA Remaining Durable striatal mHTT knockdown for 12 weeks in BACHD mouse model
Preservation of wtHTT WVE-003:
First-in-class allele-selective candidate for HD mHTT protein levels Placebo WVE-003 (30 and 60 mg pooled*) wtHTT protein levels Reductions in mean CSF mHTT and preservation of wtHTT observed in pooled analysis of single-dose cohorts in SELECT-HD
clinical study Single dose of WVE-003 Single dose of WVE-003 Reduction in mHTT protein: 22% from baseline 35% vs. placebo mHTT: mutant huntingtin protein; wtHTT: wild-type huntingtin protein *Pooled considering no apparent dose response between 2
cohorts; Data cut-off: August 29, 2022 Data from 30 mg multi-dose cohort with extended follow-up, along with all single-dose data expected 2Q 2024 Reductions in mHTT
