About Korsana Biosciences, Inc.
Korsana Biosciences, Inc. develops therapeutic antibodies for the treatment of neurodegenerative diseases. The company has developed Therapeutic Targeting (THETA), a blood-brain barrier-penetrant shuttle platform designed to enhance central nervous system exposure of investigational therapies and enable delivery of large therapeutic molecules across the blood-brain barrier into the central nervous system. The company advances a pipeline of THETA-enabled therapeutics with an initial focus on neurodegenerative disorders. Its lead product candidate is KRSA-028, an anti-amyloid beta antibody for the treatment of Alzheimer's disease, which combines the THETA platform with elements of anti-amyloid beta approaches and targets a clinically relevant form of amyloid beta designed to improve brain uptake while reducing effects on reticulocytes. The company is also advancing a pipeline of additional THETA-enabled therapies for other neurodegenerative diseases. Korsana Biosciences, Inc. was incorporated in 2024 and is based in Waltham, Massachusetts.
