Making the differenceResearchDEBRA seeks £1,881,736 in 2013 to meet our research aimsDEBRA’s knowledge of EB is increasing and weare beginning to develop treatments which weexpect, based on extensive laboratory andpreclinical research, could offer real relief topeople with EB. Research represents hope andwe endeavour to balance our commitmentbetween projects we are confident will deliverbenefit in the near term, as well as those offeringmore significant long-term outcomes.DEBRA is now seeing a rapidly changing pictureof therapies progressing from laboratoryresearch, to preclinical studies, to clinical trials. EBresearch is dynamic and it is likely that eventual“cures” will be the result of an amalgamation ofvarious approaches currently in development,together with novel technologies and concepts asyet to emerge from fundamental research into EB.• Extraordinary progress has been made in ourunderstanding of the condition since DEBRAbegan funding research. As a direct result ofyour support we now know 12 genesassociated with the classic types of EB andincreasing knowledge is revealing many newgenes – another 5 or so to date – associatedwith rarer, or previously undiagnosed forms ofEB and conditions related to EB. We are theworld leaders in our field with only around onethird of other rare genetic conditions havingalso reached the point of identifying a causativegene.• DEBRA’s highly collaborative global approach toour work enables funding to be concentrated onthe best research most likely to lead toimproved treatments, and to be totallycoordinated to avoid unnecessary andexpensive duplication of research effort. Whenselecting our advanced and ground-breakingresearch DEBRA coordinates internationallywith DEBRAs and other EB research fundersaround the world.• We see DEBRA’s unique contribution asproviding seed funding to get research projects“off the ground”. This hugely successfulapproach allows ideas to be developed in thelab and through early stage trials to get to apoint where a commercial partner sees thedevelopments as a viable investment.Growing sheets of epidermal skin cells in the lab.• Because DEBRA researchers work withinuniversities and other research institutions webenefit from the infrastructure and resources ofthese organisations – allowing every pound youdonate to work much, much harder as we don’tthen pay for rents and expensive equipment.DEBRA International’s Medical and ScientificAdvisory Panel (MSAP) Board, in conjunctionwith senior EB researchers worldwide andpatient input, states that priorities forresearch funding are:• To spend research funds roughly 50/50 splitbetween long term and more immediate neartermbenefit.• To develop our understanding and practicalapplication of gene, cell and protein therapiesto manipulate the faulty genes that cause EB inorder to provide symptom relief.• Continue to develop our understanding andpractical application of wound healingtreatments. This will be a combination ofclinical and lab work with nurses andresearchers looking at effective dressings useas well as gene and cell manipulation.• Understand why squamous cell carcinomacancer is so aggressive in EB patients, andseek to understand if available treatments canbe of benefit in the near term.• Continue our commitment to understanding thecauses and make-up of EB and improvediagnosis expertise.4
DEBRA UK is seeking funding for thefollowing projects:£450,000 Aim: Phase I/II Clinical trial ofmesenchymal stromal cells in RDEB. Prof JohnMcGrath, Great Ormond Street Hospital forChildren NHS Trust (London) and UniversityCollege London. 3 year project.Bone-marrow derived MSC are multipotent stemcells that can differentiate into cell types in a widevariety of tissue, including skin. MSC are suitedto tissue-engineering and, when transplanted inthe bloodstream, they travel to the site of injury.Findings to date suggest that injections of MSCto treat EB report some benefits and limited sideeffects. This project will perform a phase I/IIclinical trial of intravenously administered bonemarrow-derived mesenchymal stromal cells(MSCs) in 10-20 children with recessivedystrophic epidermolysis bullosa (RDEB).£97,500 Aim: To document a natural history ofEB and validate Clinical Endpoints appropriate toTherapy Evaluation by industry and regulatoryauthorities. Dr Jemma Mellerio and Dr AnnaMartinez, Great Ormond Street Hospital andGuys & St Thomas. First 2 years of planned 5year programme.With many DEBRA funded research avenues nowleading to clinical trials it is imperative thatDEBRA is in the right position to developpartnerships to move the science into patientaccessible treatments. In order to do this, weneed to facilitate regulatory approval of potentialtherapies, and be able to attract industry andventure capital to invest in getting treatments intoproduction and be able to persuade healthcarefunders to pay for the therapy.DEBRA’s Translational Research Advisory Panel(TRAP) has advised that it is important forcompanies thinking of investing in clinical trialsto know there is a clear understanding of whatthe ‘normal’ course of the condition is.Additionally we must be able to show thattreatment under trial has been effective in such away as to ensure it will be accepted by theregulators who determine whether a treatment issafe and effective enough to be approved.€260,000 Aim: To develop therapies whichcombine ex vivo gene therapy with stem celltransplantation for Junctional EB. Prof. JohannBauer (Salzburg), Prof. Michele De Luca (Italy),Prof Christopher Baum (Germany). 3 year project.This project builds upon the success of the firstex vivo skin gene therapy trial in Italy. This PhaseI/IIa clinical trial will take stem cells from an EBpatient for the production of genetically modifiedskin grafts for use on the same patient. Thesegrafts can be repeated until large parts of thedamaged layers of the skin are covered with“new” skin. In this way several of the clinicalhallmarks of EB are combated:• No more loss of body fluids thus reduction inloss of proteins and peptides• Improved barrier defence against microbialinfection• Lessening likelihood of cancer developing dueto long-standing wound areas$250,000 Aim: To develop TALEN gene-correctiontechnology re individualised stem-cell therapyoptions for children with RDEB, Dr Jakub Tolar,University of Minnesota, I year project (selectedfor funding through the Sohana Research Fund)The ultimate goal is to develop safer, moreeffective, personalised treatment options for thechildren with EB, especially those undergoingthe systemic therapy of EB commonly calledBone Marrow Transplantation (BMT). In order toavoid serious transplant associated side effects,the ideal treatment would collect the patientsown cells, correct the gene defect, and deliverthe corrected cells back to the patient.This project proposes to unify two cutting edgetechnologies, involving the generation ofinducible pluripotent stem cells (iPS) – cellscapable of differentiating into any other cell type– and the powerful gene-editing, site directed,“molecular scissors” platform known as TALENsto realise the potential of individualised,genomic-medicine-based cellular therapy for EB.By the conclusion of the project, the aim is tohave provided proof of principle for the feasibilityof a truly individualised (therefore safer andmore effective), genomics-based medicineapproach for the treatment of EB.5
