About BPN14770

BPN14770 is a novel therapeutic agent that selectively inhibits phosphodiesterase-4D (PDE4D) to enhance early and late stages of memory formation. This unique mechanism of action has the potential to improve cognitive and memory function in devastating disorders including Fragile X Syndrome, Alzheimer’s disease and other dementias, learning/developmental disabilities and schizophrenia. Tetra Discovery has initiated an investigational Phase 2 study of BPN14770 in adults with Fragile X Syndrome, an indication for which BPN14770 has received Orphan Drug Designation from the U.S. Food and Drug Administration. Preparations are also under way to initiate a Phase 2 trial of BPN14770 in patients with Alzheimer’s disease. BPN14770 is currently approved for investigational use only by the U.S. Food and Drug Administration and is not currently approved for marketing in any territory.
