About LB-102 LB-102 is a novel, once-daily, orally administered investigational small molecule and potential first benzamide antipsychotic in the United States for the treatment of neuropsychiatric disorders. A methylated derivative of amisulpride, a widely used antipsychotic outside the United States, LB-102 was developed to retain amisulpride’s benefits while addressing its limitations. LB-102 is a potent and selective antagonist of D2, D3, and 5-HT7 receptors with few off-target effects and broad therapeutic potential across psychosis and mood disorders. In early 2025, LB Pharmaceuticals announced positive data from a four-week placebo-controlled, double-blinded, Phase 2 trial in patients with acute schizophrenia. In this trial, LB-102 demonstrated statistically significant benefit versus placebo at all doses studied, including rapid onset of effect at week 1 and sustained benefit through the endpoint of the trial, a potentially class-leading safety profile with low rates of EPS (including akathisia), minimal sedation and few GI side effects, alongside effects on negative symptoms and cognitive performance. These data underscore LB-102’s potential to

address multiple dimensions of neuropsychiatric illness. The pivotal Phase 3 NOVA-2 trial of LB-102 for acute schizophrenia and the Phase 2 ILLUMINATE-1 trial of LB-102 for bipolar 1 depression are ongoing, and a Phase 2 trial of LB-102 in adjunctive treatment of MDD is planned. The Company is also pursuing additional expansion opportunities for LB-102 including predominantly negative symptoms of schizophrenia, Alzheimer’s disease psychosis and agitation, as well as other neuropsychiatric diseases. About LB Pharmaceuticals LB Pharmaceuticals is a neuromedicines company dedicated to developing and commercializing high-impact therapies that address the multiple dimensions of underserved brain diseases. The Company is building a pipeline that leverages the broad therapeutic potential of its lead product candidate, LB-102, which the Company believes has the opportunity to be the first benzamide antipsychotic drug approved for neuropsychiatric disorders in the United States. LB-102, if approved, has the potential to become a mainstay of psychiatric practice by offering a balanced clinical activity and tolerability profile that provides a potentially attractive alternative to branded and generic therapeutics for the treatment of a broad range of neuropsychiatric diseases.
