LB Pharmaceuticals Inc

We are a clinical-stage biopharmaceutical company developing novel therapies for the treatment of schizophrenia, bipolar depression, and other neuropsychiatric diseases. We are building a pipeline that leverages the broad therapeutic potential of our lead product candidate, LB-102, which we believe has the potential to be the first benzamide antipsychotic drug approved for neuropsychiatric disorders in the United States. LB-102 is a new chemical entity and a methylated derivative of amisulpride, a second-generation antipsychotic drug approved in over 50 countries, not including the United States, because the development and regulatory requirements of the U.S. Food and Drug Administration, or FDA, for amisulpride were incompatible with patent coverage on the drug. Amisulpride is a generic drug that has been extensively used in clinical practice following its initial approval in France in the 1980s, generating at least two million monthly prescriptions in 2023 in a subset of 16 continental European countries. Among these European prescriptions for amisulpride, our data suggest that approximately 60% are for schizophrenia and schizoaffective disorders, approximately 20% are for mood disorders, approximately 14% are for anxiety, and the remainder are for a variety of other indications. We developed LB-102 in order to address the limitations of amisulpride with a differentiated therapeutic profile and strong intellectual property protection. We believe LB-102’s mechanism of action
