Exon 51: WVE-210201 clinical program Current Study – Phase 1 trial to evaluate safety and tolerability • WVE-210201 Phase 1 clinical trial (ClinicalTrials.gov Identifier: NCT03508947) – Design: Multicenter, double-blind, placebo-controlled, single ascending dose study with intravenous administration – Primary endpoint: Safety and tolerability – Inclusion criteria: ages 5 to 18, amenable to exon 51 skipping • Ambulatory and non-ambulatory boys eligible, including those previously treated with eteplirsen (following appropriate washout period) • No muscle biopsy required for entry into phase 1 study – Study sites: North America and Europe – Randomization: 3: 1, active treatment to placebo; 40 boys total – Enrolling; readout expected in the third quarter of 2018 Source: Wave Life Sciences; ClinicalTrials.gov (I dentifier: NCT03508947) 6
Exon 51: WVE-210201 clinical program Next Steps – Planned Open Label Extension and Planned Efficacy Study • WVE-210201 planned open-label extension (OLE) of Phase 1 safety study – Includes muscle biopsy and ≥ 2-years of follow-up • WVE-210201 planned efficacy study being designed with the DMD community at large and with feedback from regulatory authorities. Preliminary considerations: – Design: Double-blind, placebo-controlled, multi-dose study assessing dystrophin expression and clinical outcomes – Interim analysis of dystrophin expression in muscle biopsies – Data readout anticipated in the second half of 2019 Source: Wave Life Sciences 7
