Overview of Recessive Dystrophic Epidermolysis Bullosa (RDEB) and Genetically Modified Human Dermal Fibroblasts (GM-HDF)

Problem: Patients are not producing collagen VII or producing non-functional collagen VII Cause: A mutation in the COL7A1 gene which encodes for type VII collagen – the main component of anchoring fibrils Symptoms: Blisters and lesions over widespread areas of the body Potential therapy: Genetically modify the cell to produce collagen VII and re-establish the anchoring fibrils Keratinocytes Interstitial collagen fibers (1) J. Uitto, “Molecular Therapeutics for Heritable Skin Diseases.” Milestones Cutaneous Biology, November 2012 (1) High-Level Overview RDEB

GM-HDF A genetically modified (GM) fibroblast upregulated to produce Collagen VII in a controlled manner for localized treatment of RDEB Autologous dermal fibroblast (azficel-T) transfected with a vector containing the gene for COL7A1 Cells will be expanded to clinical populations and administered directly to periphery of affected area Administered to the papillary dermis via injection Potential Advantages: Autologous therapy is believed to reduce rejection concern Localized injection avoids systemic treatment The fibroblast cellular engine may provide more control and sustained delivery of protein targets Integration into cell genome may translate to longer-term protein expression, potentially reducing dose administration cycles

No clinical trials have been or are currently being conducted with genetically modified human dermal fibroblasts. 10 June 2014: Fibrocell received orphan drug designation from FDA. 4 August 2014: Fibrocell met with FDA for a Pre-IND meeting to discuss the development path for GM-HDF. Regulatory

Chemistry, Manufacturing and Control FDA concurrence on draft manufacturing process and specifications for release of Drug Substance and Drug Product GMP manufacture of vector (CoH) In-process testing Skin tissue biopsy collection at a clinic Overnight shipment to Manufacturer Tissue enzymatic digestion Cell expansion Cell expansion in 2x 10-layer Cellstacks Wash and harvest GM-HDF Freeze and cryo-preserve GM-HDF (multiple doses) QC release testing of GM-HDF (Drug Substance) Overnight shipment (2-8C) to clinic for administration Thaw GM-HDF, wash and resuspend GM-HDF in DMEM (Drug Product) Vector transduction in 1-stack Cellstack

Preclinical and Clinical FDA concurrence on preclinical development plan obtained during Pre-IND meeting Materials and cells are being prepared for the conduct of the studies at Stanford University Three evaluations to be conducted in two studies: Multiple doses of GM-HDF in an in vitro organ culture study. Multiple doses of GM-HDF in vivo on RDEB human skin, which would be grown in vitro prior to grafting. GM-HDF administered to normal human skin on the xenograft SCID mouse model Initial clinical protocol will be a small phase 1 (~5 subjects) in adults. Feedback received from FDA is being incorporated.

40,000 or more yearly hospitalizations for severe burns1 Most cases treated at 127 U.S. burn centers Partial and full thickness (2nd/3rd degree) have potential to form scars Wounds heal by forming scar tissue which shrinks and tightens as it forms The formation of scars can restrict the normal range of motion or mobility of the surrounding areas If left untreated, can impact underlying tissues, bone and muscles Restrictive Burn Scarring Overview Courtesy of Daniel Lozano, MD; Lehigh Valley Health Network www.ameriburn.org; Goodis.

Schneider JC, Holavanahali R, Helm P, Goldstein R, Kowalske K. Contractures in burn injury: defining the problem. J Burn Care Res. 2006; 27:508-514. Patient Impact 3 “Burn scarring and contracture affecting function remain the most frustrating late complications of burn injury”1 Restrictive burn scars can have significant consequences to quality of life, including pain and reduced functionality In a prospective survey of burn survivors at one burn center, more than one-third of patients had developed at least one restrictive scar affecting a major joint at the time of hospital discharge2 Most frequently restricted large joint was the shoulder, followed by the elbow and the knee Restrictive burn scars may result in reduced mobility, limited reach, difficulties with grasping and manipulating objects, or impaired mobility of the neck and face Contractures of the upper extremities may impact activities of daily living, such as grooming, dressing, eating, and bathing and fine motor tasks2

Current Methods of Treatment No FDA approved drug or biologic therapies available Physical and occupational therapy Training for activities of daily living (ADL) Splinting Massage Pressure garments Surgery to release the contracture Flap procedures (Z-plasty) Skin grafting (full or partial thickness) Tissue expansion Although patient status limits how early such operations can be conducted, surgery on scars matured over 2 years may prolong recovery unnecessarily (Sheridan, 2004) A lack of healthy, unburned skin “can be a major issue during burn reconstruction” (Chester, 2004) 4

Role of Fibroblasts 5 Human dermal fibroblasts play an essential role in wound healing, migrating to the site of injury Injection into mature burn scars may stimulate a wound healing response Potentially breaks down existing, disorganized extracellular matrix as cells are stimulated to migrate into the injection site Potentially regenerates new, organized matrix within the wound Fibrocell has previous experience with injection of autologous fibroblasts into acute wounds and scars in case studies

Images of right lateral neck showing burn wound pre- and post-treatment Case Study Prior to treatment the patient had severely restricted range of motion of her neck and shoulder and required daily opiate analgesia for her chronic pain. The patient received a total of two 4mL azficel-T treatments in her neck region. Post-Treatment Full range of neck rotation, and pain-free Patient has stopped all analgesics Discarded cervical collar Case study by Mark Palmer, MD

 The same patient subsequently underwent treatment of her upper arm scars. Prior to treatment these scars had been severely disabling, such that she was unable to lift her arm beyond 90° due to pain. By 3 months after a single treatment of 1.5mL of azficel-T each to 2 contracted scar bands on her arm, the scars had almost disappeared and the patient had restored 180° range of motion without pain. Images of left arm showing tight contracted band of scar tissue pre- and 3 months pos- treatment Case Study Case study by Mark Palmer, MD

Case Study Able to lift arm for the first time in 10 years (3 months post-treatment) Case study by Mark Palmer, MD

Double-blind, randomized, placebo-controlled, 21 subjects Trial Initiated; 7 subjects enrolled Multi-center trial: 8 centers 6 month efficacy endpoint Subjects inclusion criteria: Unilateral restrictive burn scars of a jointed area 20-60% restriction in normal range of motion Validated Measurement Scales: Range of Motion Measurement(1) Brief Pain Index (BPI)(2) Scar Appearance – Vancouver Scar Scale(3) Restrictive Burn Scarring Phase II 9 Standard ROM measuring techniques (Parry, et al 2010) Brief Pain Inventory (BPI) numerical scale (0 to 10) (Cleeland and Ryan 1994; Tan, et al 2004) Vancouver Scar Scale (Baryza and Baryza 1995; Nedelec, et al 2000)

Conclusion Restrictive burn scars have a major impact on the quality of life for patients Current therapies are limited to physical manipulation, pressure garments and surgery Autologous fibroblasts may provide a non-surgical approach for improvement of range of motion for joints affected by restrictive burn scars 10

Part 1. Why is there so much genetic damage in hiPSCs? Part 2. Why is this important? Part 3. Can Fibrocell’s newly discovered supplement make a difference?

Part 1. There are multiple causes of genetic damage in hiPSCs Fibrocell initiated a sponsored research agreement to investigate if a simple proprietary culture media supplement could: 1) reduce oxidative and replicative stress of hiPSCs and their derivatives, 2) help hiPSCs grow faster & 3) increase the feasibility of using hiPSCs for personalized cellular therapies. Stress (oxidative/replicative) Ji et al 2014, Stem Cell Reports 2:44–51

Part 2. Why is this important? Safety is the number 1 concern of the FDA with regards to personalized hiPSC-based therapeutics. Any technology that significantly increases the safety of personalized hiPSC-based therapeutics would likely become broadly adopted. Current Market for hiPSC-based regenerative market: Extremely large any degenerative disease, disorder or injury. Current spending on stem cell media/supplements is (after salary costs) the LARGEST proportion of budget for any stem cell lab. Future Market for our supplement: depend on scientific, political and regulatory developments - CIDMOD Initiative - Over $500,000,000 left to spend on stem cell research in CA from CIRM alone!

Does it work? Our supplement can significantly rescue dNTP pools in hiPSCs.

n = 12 27% increase in doubling rate with supplement ** ** = p<0.05 ** 35% increase in doubling rate with supplement ** = p<0.05 n = 12 ** 13% increase in doubling rate with supplement n = 20 Cell counts of fibroblasts and stem cells grown with and without supplement were taken at 0 and 48 hours post-plating. For the AD1 stem cells, one subclone that had been reprogrammed with culture supplement was taken off supplement temporarily to conduct doubling rate experiment. Equation used to calculate population doubling time (PDT) 48 hours post-plating: 48 / (LOG(T48) – LOG(T0)) To calculate doubling rate per 24 hours: 24 / PDT ** = p<0.05 Stem cells AND somatic cells grow much faster with our supplement

Patient’s skin cells can be reprogrammed into morphologically normal stem cells in the presence of our supplement Day 10: potential stem cell colonies emerge after plating lentiviral-transduced dermal fibroblasts onto mouse feeder cells (no supplement) (with supplement) Day 28: Putative stem cells before subclone selection and transfer onto new feeder cells Conversion to feeder-free conditions: Colonies were picked from feeder cells onto Matrigel and converted to defined feeder-free stem cell culture media

Part 1. Why is there so much genetic damage in hiPSCs? The two most important reasons are oxidative and replicative stress. Part 2. Why is this important? High genetic damage is directly correlated to increased safety concerns, a major focus of current and future FDA regulations. Part 3. Can Fibrocell’s newly discovered supplement make a difference? Preliminary evidence is that Fibrocell supplement can: 3.1 Decrease stress on stem cells 3.2 Allow stem cells to grow faster 3.3 Allow stem cells to differentiate into large numbers of clinically relevant cells (such as liver cells). Future directions: Complete research & development of supplement and then commercialize with partners, for academic and industry usage.
