4D Molecular Therapeutics Announces Upcoming Oral and Poster Presentations at the 23rd Annual Meeting of the American Society of Gene and Cell Therapy

April 29, 2020 11:05 UTC
  • Oral presentations to include data on 4D-310 Product Candidate for Fabry Disease and 4D-A101 Aerosol Vector for Cystic Fibrosis and other Lung Diseases
  • Additional poster presentations to include data on 4D-C102 IV Low Dose Vector for Lysosomal Storage Diseases and Neuromuscular Diseases

EMERYVILLE, Calif.--(BUSINESS WIRE)-- 4D Molecular Therapeutics Inc. (4DMT), a leader in precision-guided AAV gene medicines based on directed evolution, today announced the company will present two oral and two poster presentations at the American Society of Gene and Cell Therapy’s 23rd Annual Meeting, to be held virtually May 12-15, 2020.

These data will highlight the following preclinical evidence: safety and efficacy of the company’s product candidate 4D-310 in both human cell (in vitro) and animal (in vivo) models of Fabry disease; diffuse payload delivery and gene expression throughout the primate lung with the proprietary aerosol-delivered vector 4D-A101; diffuse payload delivery and gene expression throughout primate cardiac and skeletal muscle tissue with the proprietary low dose IV vector 4D-C102; improved targeting of cardiac and skeletal muscle tissue versus the liver in primates with low dose 4D-C102 as compared to conventional AAV vectors; improved transduction of human cardiomyocytes and skeletal muscle cells with 4D-C102 versus conventional AAV vectors.

“We are looking forward to sharing these important advances for our differentiated product candidates and industrialized directed evolution-based vector discovery platform. These data add to the growing body of evidence demonstrating our proprietary vectors solve the key challenges facing conventional AAV vectors that are in clinical and pre-clinical development today,” said David Kirn, MD, CEO and Chairman of 4DMT.

About 4DMT

4DMT is a precision gene medicines company harnessing the power of directed evolution to unlock the full potential of gene therapy for rare and large market diseases in lysosomal storage diseases, ophthalmology, neuromuscular diseases and cystic fibrosis. 4DMT’s proprietary Therapeutic Vector Evolution platform enables a “disease first” approach to product discovery and development, thereby allowing customization of AAV vectors to target specific tissue types associated with the underlying disease. These proprietary AAV vectors are designed to provide targeted delivery by routine clinical routes, efficient transduction, reduced immunogenicity and resistance to pre-existing antibodies -- attributes that could enable the development of gene therapies that overcome known limitations of conventional AAVs. 4DMT vectors are designed to exhibit improved therapeutic profiles that enable the company to pursue previously untreatable diseases and to address a broad range of rare and large market diseases.
