MeiraGTx Expands ALS Gene Therapy Program in Collaboration with Weill Cornell Medicine and LSU

— Program seeks to treat ALS patients by activating cells’ own quality control mechanisms

NEW YORK, October 11, 2016 – MeiraGTx, a New York and UK based gene therapy company, announces an expansion of its gene therapy program to treat amyotrophic lateral sclerosis (Lou Gehrig’s Disease, ALS).

MeiraGTx, together with Prof. Gregory Petsko, D.Phil. (The Arthur J. Mahon Professor of Neuroscience in the Feil Family Brain and Mind Research Institute at Weill Cornell Medicine), and Prof. Ronald Klein, Ph.D. (Associate Professor Department of Pharmacology, Toxicology and Neuroscience, LSU Health Shreveport), are developing a gene therapy to target TDP-43 toxicity in ALS patients. The cellular protein TDP-43 is misregulated in the vast majority of all ALS patients and is emerging as a possible Achilles’ heel in the treatment of this deadly neurodegenerative disease.

Research conducted in the Petsko laboratory (in collaboration with coworkers at Brandeis University, Wright State University and the University of Michigan) revealed that one of the cell’s own quality control mechanisms, called the nonsense-mediated decay (NMD) pathway, can alleviate TDP-43 mediated toxicity in cell-based disease models of ALS. Increased expression of UPF1, the master regulator of NMD, significantly protects mammalian motor neurons from TDP-43 mediated toxicity. “UPF1 has shown promising results in animal models of ALS involving TDP-43 dysfunction and provides a rationale for developing gene-based therapies for ALS, and we are excited about moving this forward with a company that has the scientific insights of MeiraGTx” said Dr. Petsko. MeiraGTx recently entered into a research collaboration with Professor Klein of Louisiana State University (LSU) to conduct pre-clinical animal studies aimed at demonstrating the efficacy of a UPF1-based therapy in animal models of TDP-43 induced ALS pioneered in his laboratory.

MeiraGTx and its academic collaborators are defining the role of RNA metabolism in the pathology of ALS, with the goal of developing effective gene therapies. “We are very excited about our work with Drs. Petsko and Klein, leaders in the field of neurodegeneration, to develop a gene therapy targeting TDP-43 dysfunction in ALS,” said Alexandria Forbes, Ph.D., President and CEO of MeiraGTx. “We believe that this may lead to not only an important new therapeutic approach, but further investigation of the genetic causes of ALS will provide insight for the development of additional gene therapies to treat this and other devastating neurodegenerative diseases.”



About MeiraGTx

MeiraGTx is committed to the development of novel gene therapies to transform the lives of patients suffering from acquired and inherited disorders. The company is developing treatments for ocular diseases, including rare inherited blindness and age-related macular degeneration (AMD). MeiraGTx is also establishing treatments for xerostomia, a frequent and debilitating side effect of radiation treatment used in head and neck cancers, as well as certain neurodegenerative diseases. In addition, MeiraGTx is developing novel gene regulation platforms that promise to transform the way gene therapy can be applied and create new paradigms for biologic therapeutics.
