FCX-007 Phase 1/2 Clinical Trial Design A Phase 1/2 Trial of FCX-007 (Genetically-Modified Autologous Human Dermal Fibroblasts) Title for Recessive Dystrophic Epidermolysis Bullosa (RDEB) NCT02810951 Primary Objective To evaluate the safety of a single intradermal injection session of FCX-007 • Pharmacology using immunofluorescence (IF), immunoelectron microcopy (IEM) and qPCR in wound and intact skin areas • Percent wound healing compared to baseline evaluation: Secondary Objectives . Wounds were evaluated during a monitoring period prior to dosing and were observed to be open up to 8 months . A matched size, untreated wound for each treated wound on the same patient was also monitored and evaluated • Stanford University School of Medicine Investigator Sites • Children’s Hospital Colorado Phase 1 Status • Four patients enrolled and dosed, continuing follow-up visits to 52 weeks • Obtained FDA allowance to initiate enrollment of pediatric patients Phase 2 Status • Six patients ages seven and older targeted for enrollment • One patient enrolled, three scheduled for screening visits prior to the end of June 2018 9
Interim Update • Selected to present data at the International Investigative Dermatology (IID) meeting in Orlando on May 19, 2018 Dosing Parameters Number of adult patients dosed 4 Patient age range 20 - 37 Number of wounds treated 7 Wound size range (cm2) 4.4 - 23.2 Cell dose concentration range (cells/mL) 1.4 x 107 - 2.5 x 107 • Administered a single intradermal injection session at baseline to assess safety prior to increasing dose regimen . One patient received a second injection session in the remaining unhealed areas of the wound 25 weeks post-administration after the baseline dose • Performed on an outpatient basis using conscious sedation rather than in a surgical suite under general anesthesia • FCX-007 continues to be well tolerated up to 52 weeks post-administration . No serious adverse events or product related adverse events . No replication competent lentivirus (RCL) detected . No autoantibody response detected, including one null genotype patient (NC-1-) 10

Phase 1 Observations • Product is well-tolerated up to 52 weeks post-administration, with no evidence of circulating autoantibodies to COL7 • Pharmacology: . Variable pharmacology signals continue to be detected throughout the data set out to 52 weeks post-administration, including COL7 expression using IF and IEM, and anchoring fibrils using IEM . Increased expression of COL7 over time noted using IF . Patients dosed with higher cell concentrations resulted in more robust COL7 expression signals . LV-COL7 vector was detected in skin 25 weeks post-administration, indicating FCX-007 cells are still present in the skin • Wound healing: . Positive healing trends maintained at 4 and 12 weeks post-administration . The majority of untreated control wounds are unhealed out to 12 weeks post-administration . A higher healing percentage is noted 25 weeks and beyond post-administration of FCX-007 compared to untreated control, but a larger data set is required to comment on trends . A patient’s wound receiving second injection at 25 weeks exhibited continued healing effect at 32 weeks . Based on observations, the addition of a second dose at 12 weeks post-administration may contribute to effect durability . Wound selection and classification is important for evaluation success 14
Moving Forward with Phase 2 • Based on safety, pharmacology and wound healing data, we plan to continue exploring dose range and administration to ensure robust information in support of future clinical study, including: . Addition of another injection session in the dose series . Increase in cells administered per injection session . Higher cell concentration targets • Three additional patients are scheduled for screening visits prior to the end of June 2018 . On track to achieve milestone of completing enrollment in 3Q2018 • 2018-2019 FCX-007 anticipated milestones: January 2018 2Q2018 3Q2018 1Q2019 FDA allowance of Interim Phase 1 data Complete enrollment Interim data readout pediatric patient readout and trial of Phase 2 patients and trial update enrollment in Phase 2 update Dose first Phase 2 patient 15
