Atalanta Therapeutics is a Boston-based biotechnology company pioneering RNA interference (RNAi) therapies for diseases of the brain and spinal cord. Its proprietary divalent small interfering RNA (di-siRNA) platform is engineered to silence disease-causing genes durably and broadly across the central nervous system - long the hardest place in the body to reach with RNAi. Founded out of the RNA Therapeutics Institute at UMass Chan Medical School by leaders in the RNAi field, including Nobel laureate Craig Mello, the company is advancing wholly-owned programs in KCNT1-related epilepsy and Huntington's disease toward the clinic, alongside collaborations with Biogen and Genentech.
Joanne Kotz is a chemist-turned-biotech-CEO who runs Atalanta Therapeutics, a Boston company using divalent siRNA to silence disease-causing genes throughout the brain and spinal cord. She took the top job in June 2025 after co-founding and leading Jnana Therapeutics from a blank slate to a roughly $1 billion acquisition by Otsuka. Before founding companies she helped build them from the science up, as a director at the Broad Institute, a leader of F-Prime's neurodegeneration initiative, and the founding editor of Nature Chemical Biology. Her career runs an unusual loop: bench scientist, science journal editor, partnership architect, founder, and now CEO of a company chasing some of the hardest diseases in the central nervous system.
