Dystrophic Epidermolysis Bullosa and B-VEC Dystrophic epidermolysis bullosa (DEB) is a serious, ultra-rare genetic blistering disease caused by mutations in the COL7A1 gene which lead to skin fragility and wounds1-3 Patients with DEB are at increased risk for serious complications, including aggressive squamous cell carcinoma4-6; management is currently supportive in nature7,8 Beremagene geperpavec (B-VEC) is an investigational HSV-1-based topical, redosable gene therapy designed to restore functional COL7 protein by delivering the COL7A1 gene B-VEC utilizes a differentiated HSV-1 vector platform that allows for episomal delivery, high payload capacity, tropism for skin cells, and evades the immune system enabling repeat delivery 1.

GEM-3 Study Design B-VEC, beremagene geperpavec; DEB, dystrophic epidermolysis bullosa GEM-3 (NCT04491604) is a Phase 3, multicenter, randomized, double-blind, placebo-controlled intra-patient study evaluating the efficacy and safety of B-VEC in patients with DEB B-VEC Placebo Randomized, double-blind 6-month treatment period Open-label 6-month treatment period Secondary Wounds 31 Patients Enrolled Age ≥ 6 months Genetically confirmed DEB Two cutaneous wounds similar in size, appearance, and anatomical regions Primary Wound Pair 30-day safety period Once weekly treatment until wound closure; treatment resumed if wound reopened Dosing continues after safety period Open-label extension period B-VEC Remaining weekly dose used to treat up to four secondary wounds Secondary Efficacy Endpoints Complete wound healing* at Weeks 8 & 10 or Weeks 10 & 12 (3 months) Mean change in pain severity associated with wound dressing changes Primary Efficacy Endpoint Complete wound healing* at Weeks 22 & 24 or Weeks 24 & 26 (6 months) *Complete wound healing defined as 100% wound closure from exact wound area at baseline, specified as skin re-epithelialization without drainage 8

Patient Disposition 31 patients were randomized and made up the intent-to-treat (ITT) population used for all primary and secondary efficacy analyses The safety population was the same as the ITT population and used for all safety analyses Three patients withdrew from the study for nondrug-related reasons B-VEC, beremagene geperpavec; ITT, intent-to-treat 31 patients screened and enrolled 30 patients completed through Week 12 One primary wound pair per patient randomized 1:1 28 patients completed through Week 26 1 withdrawal after Week 6 31 primary wounds received B-VEC 31 primary wounds received placebo 1 withdrawal after Week 12 1 withdrawal after Week 24 9

Slide 11

Significantly Greater Complete Wound Healing with B-VEC Treatment The proportion of primary wounds with complete wound healing was significantly greater with B-VEC than placebo at both 3- and 6-month timepoints (p <0.005) In the patient with DDEB, primary endpoint of complete wound healing at 6 months was achieved by the B-VEC treated wound, but not by the placebo treated wound At 6 months, 15 of 17 discordant pairs showed response to B-VEC but not placebo Discordant pair defined as when one wound meets complete wound healing responder definition and other does not Data as of database lock on 19Nov2021; data in figure based on ITT population (imputed); p-values and CIs are based on exact McNemar’s test B-VEC, beremagene geperpavec; CI, confidence interval; DDEB, dominant dystrophic epidermolysis bullosa; ITT, intent-to-treat 67.4% 21.6% 70.3% 20.0% 45.8% absolute difference (95% CI 23.6 – 68.0%) p < 0.005 50.3% absolute difference (95% CI 28.7 – 72.0%) p < 0.005 B-VEC Placebo Proportion of Primary Wounds with Complete Wound Healing in the ITT Population (n= 31) 6 Months (Primary Endpoint) 3 Months (Key Secondary Endpoint) 11

Consistent Evidence of a Treatment Response with B-VEC Across Subgroups Treatment response was in favor of B-VEC for all gender, age, and wound area/size subgroups, however the individual subgroups were not powered to demonstrate statistical significance Data as of database lock on 19Nov2021; data in figures based on ITT population (imputed); p-values and CIs are based on exact McNemar’s test; gender and age subgroups were pre-specified B-VEC, beremagene geperpavec; CI, confidence interval; ITT, intent-to-treat Favors B-VEC Favors placebo Gender Male (n=20) Female (n=11) ≤12 years (n=10) >12 and ≤18 years (n=9) >18 years (n=12) Absolute Difference, % (95% CI) Complete Wound Healing at 6 Months by Gender and Age Subgroups Age Baseline primary wound area/size category* B-VEC Placebo N Complete wound healing at 6 months, n (%) N Complete wound healing at 6 months, n (%) <20 cm2 23 14 (60.9) 22 5 (22.7) 20 - <40 cm2 6 4 (66.7) 8 1 (12.5) 40 – 60 cm2 2 1 (50.0) 1 0 (0) *In a small number of patients, the pre-defined threshold values for wound area/size category fell in between the size of the two wounds Complete Wound Healing at 6 Months by Baseline Primary Wound Area/Size Category 14

Pain and PRO Assessments Demonstrated Improvement Consistent with a Wound Healing Response Baseline VAS score of enrolled patients were approximately 2 to 3 on average A trend towards decreased pain in B-VEC treated versus placebo treated wounds was observed across Weeks 22, 24, and 26; improvement in pain was consistent with wound healing PRO measures (EQ-5D-5L and Skindex-29) assessed before and after treatment with B-VEC demonstrated improvement across multiple domains directionally, consistent with a wound healing response Data as of database lock on 19Nov2021 B-VEC, beremagene geperpavec; ITT, intent-to-treat; PRO, patient reported outcomes; VAS, Visual Analog Scale Change from baseline in pain severity associated with wound dressing changes, as measured by Visual Analog Scale, at Weeks 22, 24, and 26 for the ITT population, ages 6 and above Least square mean difference, 95% CI (shown as error bars), and p values were generated from analysis of covariance linear model with treatment and subject as the fixed effects and the baseline value as the covariate and change from baseline as the dependent variable Change from Baseline in Pain following B-VEC Treatment Week 22 Week 24 Week 26 15 p = 0.02 p = 0.06 p = 0.07
