Senior Consultant Houria Bachtarzi

Houria Bachtarzi, DPhil, MPharm, M.R.Pharm.S

SENIOR CONSULTANT

14+ years of experience in in vivo and ex vivo gene therapies; combined with extensive CMC gap analyses and regulatory/development strategies for genetically modified cells for tissue regeneration, virally vectored gene therapy products, in vivo and ex vivo genome editing, genetically engineered immune cells targeting cancer cells and stem cell-based products.   

ABOUT HOURIA

Houria joined Dark Horse Consulting in July 2020, bringing profound knowledge and expertise in gene engineering, genetically modified replication-deficient and replication competent (for oncolytic viral therapy) viral vectors, notably those based on adeno-associated viruses, adenoviruses, lentiviruses/retroviruses, vaccinia virus and herpes simplex virus for in vivo and ex vivo applications. Having worked in advanced biological therapies for indications as complex as cancer and muscular dystrophies, and at the interface between academia and industry for the last 14 years, she understands the unique challenges ahead that the gene and cell therapy field is still faced with to reach its optimal potential.

Houria started her career by first training and registering as a Pharmacist in the UK, before embarking into a unique journey in gene therapy and regenerative medicine.  She completed her PhD in cancer gene therapy at the University of Oxford, Department of Oncology (previously Department of Clinical Pharmacology), addressing a fundamental barrier to a successful clinical application of systemically delivered oncolytic viral-based gene therapy.  She subsequently followed up with additional post-doctoral work in AAV-based gene therapy and shRNA therapeutics for degenerative neuro-muscular disorders at the Centre for Biomedical Sciences, Royal Holloway – University of London, where she played a tremendous role in the early gene construct design, vector production and proof-of-concept studies of dual AAV vectors as part of a “gene silencing and replacement” treatment for Oculopharyngeal Muscular Dystrophy (OPMD) in collaboration with Benitec Biopharma, Inc. and the Institute of Myology at the Pitié-Salpétrière Hospital in Paris, France. 

In 2013, Houria was appointed as a Lecturer in Biopharmaceutics and Biotechnology at the School of Pharmacy and Biomolecular Sciences, University of Brighton, where she continued her collaboration with the gene and cell therapy research group at Royal Holloway – University of London as an academic visitor. She also established new links and collaboration with the Brighton Centre for Regenerative Medicine and Devices and was teaching pharmacy and biomedical sciences students, covering diverse topics including: medicines design/drug discovery; biopharmaceutics; principles of pharmacokinetics and pharmacodynamics; regulatory affairs; pharmaceutical manufacturing and microbiological/biotechnological aspects of medicines production.

Prior to joining Dark Horse Consulting, Houria was a Senior Consultant in Gene and Cell Therapies at other regulatory and product development consultancies: ERA Consulting (UK) Ltd. and NDA Group, where she provided CMC and regulatory/development strategic advice in relation to different complex gene and cell therapy technologies notably: genetically modified cells for cancer and tissue regeneration, in vivo viral gene therapy products for monogenic diseases, genome editing and stem cell-based products. She also provided expert advice on matters related to genetically modified organisms (GMOs). She was heavily involved and successfully contributed to the IND approval of one of the first gene edited off-the-shelf CAR T-cell product and the clinical trial approval of the first in vivo genome editing products in Europe.
