NEW YORK, Nov. 06, 2025 (GLOBE NEWSWIRE) -- LB Pharmaceuticals Inc ("LB Pharmaceuticals" or the "Company") (NASDAQ:LBRX) today announced financial results for the third quarter ended on September 30, 2025 and provided recent corporate updates.

"Following our recent initial public offering, we are well-positioned to continue executing on our strategy to advance LB-102 into a Phase 3 trial in acute schizophrenia, as well as a Phase 2 trial in bipolar depression," said Heather Turner, Chief Executive Officer of LB Pharmaceuticals. "The robust and statistically significant results recently reported from our potentially registrational Phase 2 trial in acute schizophrenia confirm the meaningful clinical impact and differentiated tolerability of LB-102, which we believe has the potential to be the first benzamide antipsychotic drug approved for neuropsychiatric disorders in the United States. Our team is focused on advancing LB-102 towards FDA approval to expand treatment options for underserved patients."

Recent Corporate Updates

In September 2025, the Company announced the pricing of its upsized initial public offering of 21,850,000 shares of its common stock at a price of $15.00 per share. The aggregate gross proceeds to LB Pharmaceuticals from the offering were $327.8 million.
In October 2025, the Company presented three posters featuring new and previously reported analyses from its Phase 2 NOVA¹ clinical trial of LB-102 in acute schizophrenia at the 38th European College of Neuropsychopharmacology ("ECNP") Congress, which took place in Amsterdam, The Netherlands, from October 11-14, 2025. Using a validated battery of cognitive tests in its Phase 2 acute schizophrenia trial, a post-hoc analysis demonstrated that after four weeks of treatment with LB-102, a robust, dose-dependent, and significant treatment effect size was identified in a completer population for all doses of LB-102 compared with placebo. The treatment effect size versus placebo was 0.26 (p=0.0476) at the 50 mg dose, 0.41 (p=0.0027) at the 75 mg dose and reached 0.66 (p=0.0018) at the 100 mg dose. Significant effect sizes of the magnitude reported in this trial provide early evidence that LB-102 may positively impact cognitive deficits—an area of significant unmet need that spans across schizophrenia and mood disorders.
- The Company presented two additional posters at ECNP, which included an encore presentation of the primary efficacy and safety results from the NOVA¹ trial, and a post-hoc analysis focused on the effects of LB-102 on negative symptoms in a subset of patients with prominent negative symptoms at baseline.
- Collectively, these analyses further reinforce LB-102's balanced clinical profile, which is characterized by clinically meaningful reduction in Positive and Negative Syndrome Scale ("PANSS") scores, a generally favorable and potentially class-leading tolerability profile and differentiated clinical activity across multiple symptom domains.

To increase the statistical power of its planned Phase 3 clinical trial in acute schizophrenia, the Company plans to increase the sample size of this trial from approximately 400 patients to approximately 460 patients. The Company is planning to initiate this trial in the first quarter of 2026 and continues to expect to report topline data for this trial in the second half of 2027.
The Company also plans to initiate a potentially registrational Phase 2 trial in bipolar depression in the first quarter of 2026 and expects to report topline data for this trial in the first quarter of 2028.

New Team Appointments

In September 2025, the Company announced the appointments of William Kane and Rekha Hemrajani to its Board of Directors. These new Board members add valuable expertise in finance, business development, CNS product commercialization, and corporate strategy.
In October 2025, LB Pharmaceuticals announced the appointment of James Rawls, Pharm.D., as Senior Vice President of Regulatory Affairs. Throughout his career, Dr. Rawls has led or contributed to more than a dozen successful regulatory filings and product approvals in the United States, Europe, and Japan, with specific experience in neuropsychiatric diseases.

Financial Results for the Three Months ended September 30, 2025

Research & Development Expenses:

Research and development expenses were $2.4 million for the third quarter of 2025, as compared to $10.7 million in the third quarter of 2024. The decrease was primarily due to a decrease in clinical trial expenses related to the conduct of our Phase 2 clinical trial of LB-102 in acute schizophrenia in 2024.

General & Administrative Expenses:

General and administrative expenses were $2.8 million for the third quarter of 2025, as compared to $5.4 million for the third quarter of 2024. The decrease was primarily due to the write-off of deferred financing costs in 2024.

Net Loss:

Net loss was $3.6 million for the third quarter of 2025, as compared to a net loss of $14.2 million for the third quarter of 2024.

Cash Position:

Cash, cash equivalents and marketable securities as of September 30, 2025 were approximately $314.5 million following the Company's initial public offering in September.

Research & Development Expenses:

Research and development expenses were $8.3 million for the nine months ended September 30, 2025, as compared to $50.8 million for the nine months ended September 30, 2024.

General and administrative expenses were $8.3 million for the nine months ended September 30, 2025, as compared to $8.5 million for the nine months ended September 30, 2024.

About LB-102

LB-102 is a Phase 3-ready oral, small molecule and a methylated derivative of amisulpride. In early 2025, LB Pharmaceuticals announced positive data from a four-week placebo-controlled, double-blinded, Phase 2 trial in patients with acute schizophrenia. The Phase 2 trial demonstrated statistically significant benefit versus placebo at all doses studied, a potentially class leading safety profile among D2 antagonists and partial agonists, and positive effects on negative symptoms and cognition. LB-102 is advancing into a Phase 3 clinical trial for acute schizophrenia and a Phase 2 clinical trial for bipolar depression. Additional expansion opportunities for LB-102 could include major depressive disorder (MDD), predominantly negative symptoms of schizophrenia, Alzheimer's disease psychosis and agitation, as well as bipolar mania and cognitive impairment associated with schizophrenia.

About LB Pharmaceuticals

LB Pharmaceuticals is a clinical-stage biopharmaceutical company developing novel therapies for the treatment of schizophrenia, bipolar depression, and other neuropsychiatric 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 potential 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 potentially attractive alternative to branded and generic therapeutics for the treatment of schizophrenia, bipolar depression, and other neuropsychiatric diseases.
