4D Molecular Therapeutics develops gene therapies aimed at treating serious genetic diseases by delivering specific genetic material to patients' cells. The company utilizes a unique technology called Therapeutic Vector Evolution to create adeno-associated virus (AAV) vectors, which act as delivery vehicles for therapeutic genes targeting affected cells in the body. Unlike many competitors, 4DMT focuses on precision medicine for genetic disorders, including cystic fibrosis, and operates in the specialized biopharmaceutical market. Their goal is to advance gene therapies through rigorous research and clinical trials, ultimately commercializing effective treatments either directly or through partnerships with larger pharmaceutical companies.
