NEW YORK, May 12, 2026 (GLOBE NEWSWIRE) -- LB Pharmaceuticals Inc ("LB Pharmaceuticals" or the "Company") (NASDAQ:LBRX), a late-stage biopharmaceutical company developing novel therapies for schizophrenia, bipolar depression, adjunctive treatment of MDD, and other neuropsychiatric diseases, today announced financial results for the first quarter ended on March 31, 2026 and provided a corporate update.

"With multiple clinical trials ongoing, our focus is on execution to support several clinical readouts over the next three years that have the potential to unlock tremendous value of LB-102 in both psychosis and mood disorder indications," said Heather Turner, Chief Executive Officer of LB Pharmaceuticals. "We remain on track for topline data from NOVA-2 in schizophrenia in the second half of 2027, from ILLUMINATE-1 in bipolar depression in the first quarter of 2028 and in adjunctive MDD in the first half of 2029. Our recent successful financing supports the expansion of our pipeline and positions us to advance our strategy of building a fully integrated neuropsychiatric company."

First Quarter 2026 and Recent Highlights

The Company is building a pipeline that leverages the broad therapeutic potential of LB-102, which has the opportunity to be the first benzamide antipsychotic drug approved for neuropsychiatric disorders in the United States.

LB-102 in Schizophrenia

Initiated the pivotal Phase 3 NOVA-2 trial evaluating the efficacy and safety of LB-102 in patients with acute schizophrenia in March 2026, with topline data expected in the second half of 2027.
Initiated the 52-week open-label safety and tolerability trial (NOVA-3) to evaluate the long-term safety and tolerability of LB-102 in patients with stable schizophrenia
Published results from the Phase 2 NOVA-1 trial of LB-102 in schizophrenia in The Journal of the American Medical Association (JAMA) Psychiatry.
Presented new data from the Phase 2 NOVA-1 trial at the 2026 Annual Congress of the Schizophrenia International Research Society (SIRS) in March 2026. A poster presentation highlighted a post hoc analysis designed to assess whether the improvement in cognitive performance demonstrated in the Phase 2 NOVA-1 trial, as measured by the Global Cognition composite score, was a direct effect of LB-102 or an indirect consequence of the effect of LB-102 on total schizophrenia symptoms. Results of the analysis demonstrated that the cognitive benefit was primarily, and statistically significantly, a direct effect of LB‑102.

LB-102 in Mood Disorders: Bipolar Depression and Adjunctive Treatment of MDD

Initiated the Phase 2 ILLUMINATE-1 trial evaluating the efficacy and safety of LB-102 in patients with bipolar 1 depression in January 2026, with topline data expected in the first quarter of 2028.
Announced the further expansion of the LB-102 development program in mood disorders, with plans to initiate a Phase 2 trial in the adjunctive treatment of MDD in early 2027, with topline data expected in the first half of 2029.

Corporate Updates

The Company further strengthened its board, with the appointment of Robert Lenz, M.D., Ph.D., and its executive team with several key hires to support the advancement of LB-102.
In February 2026, the Company announced a private placement of $100 million with participation from new and existing institutional investors. Net proceeds were approximately $93.8 million, after deducting financial advisory fees and other financing expenses.

Financial Results for First Quarter 2026

Research & Development Expenses: Research and development expenses were $14.6 million for the three months ended March 31, 2026, compared to $3.4 million for the three months ended March 31, 2025. The increase of $11.2 million was primarily due to a (i) $7.6 million increase in clinical trial expenses related to the conduct of our Phase 2 trial of LB-102 in the treatment of patients with bipolar 1 depression and our Phase 3 trial of LB-102 in the treatment of patients with acute schizophrenia; (ii) a $1.7 million increase in expenses related to the formulation and production of LB-102 for use in our active and planned clinical trials; (iii) a $0.5 million increase in preclinical and other direct expenses primarily related to preclinical testing of LB-102; (iv) a $0.9 million increase in personnel-related expenses primarily due to an increase in headcount; and (v) a $0.6 million increase in other research and development expenses, primarily due to increased use of consultants.
General & Administrative Expenses: General and administrative expenses were $7.5 million for the three months ended March 31, 2026, compared to $3.0 million for the three months ended March 31, 2025. The increase of $4.5 million was due to (i) a $1.5 million increase in personnel-related expenses primarily due to an increase in headcount; (ii) a $1.6 million increase in stock-based compensation expense primarily related to stock options granted and repriced in connection with the IPO, as well as new hire grants; and (iii) a $1.4 million increase in professional fees, including accounting and legal fees and consulting fees.
Net Loss: Net loss was $19.1 million for the three months ended March 31, 2026, as compared to $5.3 million for the three months ended March 31, 2025.
Cash Position: Cash, cash equivalents and marketable securities as of March 31, 2026 were approximately $365.6 million. Based on current operating assumptions, the Company anticipates its current cash, cash equivalents, and marketable securities will support its planned operations into the second quarter of 2029.

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 5HT-7 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 have been initiated, and a Phase 2 trial of LB-102 in adjunctive treatment of MDD is planned. Additional expansion opportunities for LB-102 include predominantly negative symptoms of schizophrenia, Alzheimer's disease psychosis and agitation, as well as other neuropsychiatric diseases.
