Current report

Pursuant to Amended and Restated Royalty Participation Agreements entered into in August 2023, for which no consideration was received, we are obligated to pay certain investors, co-founders, and current and former directors and executive officers royalties on worldwide net sales of LB-102 in perpetuity, whether such sales are made by us or a licensee. As of September 30, 2026 and December 31, 2025, current and former directors and executive officers and their affiliates held 1.13% of these royalty interests.

Current report

30, 2026 and resulted in aggregate gross proceeds of $150.0 million, consisting of approximately $125.0 million from the sale of common stock and approximately $25.0 million from the sale of pre-funded warrants. Net proceeds were approximately $140.9 million, after deducting financial advisory fees and other financing costs of approximately $9.1 million. The pre-funded warrants are exercisable at any time for $0.0001 per share, have no expiration date, and are classified in permanent equity. In connection with the July private placement, we filed a registration statement on Form S-3ASR (File No. 333-299235) on October 1, 2026 (the “S-3 Registration Statement”), which became automatically effective upon filing. The S-3 Registration Statement also registered any and all unsold or unissued shares of common stock by the selling stockholders under the S-1 Registration Statement. Upon the effectiveness of the S-3 Registration Statement, we filed a post-effective amendment and terminated any and all offerings of our securities pursuant to the S-1 Registration Statement.

Current report

On October 1, 2026, we entered into a Sales Agreement (the “Sales Agreement”) with TD Securities (USA) LLC (“TD Cowen”) with respect to an “at-the-market” offering program, pursuant to which we may issue and sell, from time to time, shares of our common stock, par value $0.0001 per share. The issuance and sale, if any, of shares of our common stock under the Sales Agreement will be effected pursuant to the S-3 Registration Statement, which automatically became effective upon filing with the SEC on October 1, 2026. In accordance with the terms of the Sales Agreement, we may offer and sell shares of our common stock having an aggregate offering price of up to $200.0 million from time to time through TD Cowen.

Current report

Cash provided by financing activities for the nine months ended September 30, 2025 was $303.7 million primarily related to the proceeds from the IPO, net of issuance costs.
Removed paragraphs (34)

Previous report

In August 2023, contemporaneously with the closing of the Series C financing, we entered into several Amended and Restated Royalty Agreements with certain of our existing investors, co-founders, former and current directors, and former and current executive officers, including Zachary Prensky, Andrew Vaino, Ph.D., and Marc Panoff, none of whom were new investors of our Series C preferred stock. We received no consideration as part of the Amended and Restated Royalty Agreements. Pursuant to the Amended and Restated Royalty Agreements, we are obligated to pay royalties to all of the holders in an aggregate amount up to 2.75% of net sales arising from LB-102 worldwide through December 31, 2035. Thereafter, we are obligated to pay royalties to such holders in an aggregate amount up to 3.25% in perpetuity. Net sales are defined in these agreements as the gross payments received on total commercial sales of LB-102 less certain standard deductions, whether received by us or any licensee of LB-102. As of June 30, 2026, certain of our former and current officers and their affiliates held 1.13% of the future royalties.

Previous report

The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming. Furthermore, product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. The actual probability of success for our product candidates may be affected by a variety of factors, including the safety and efficacy of our product candidates, conduct of clinical trials, investment in our clinical programs, competition, manufacturing capability, and commercial viability. We may never succeed in achieving regulatory approval for any of our product candidates. As a result of the uncertainties discussed above, we are unable to determine the duration and completion of costs of our research and development projects or if, when, and to what extent we will generate revenue from the commercialization and sale of LB-102 or any future product candidates, if approved by the FDA and other applicable regulatory authorities.

Reworded paragraphs (34)

Previous wording

We are a neuromedicines company dedicated to developing and commercializing high-impact therapies that address the multiple dimensions of underserved brain diseases. Our growing pipeline leverages the broad therapeutic potential of our lead product candidate, LB-102, which we believe has the opportunity to be the first benzamide antipsychotic drug approved for neuropsychiatric disorders in the United States. LB-102 is currently in late-stage clinical development for schizophrenia (pivotal Phase 3 NOVA-2 trial) and bipolar depression (Phase 2 ILLUMINATE-1 trial). Concurrently with the Phase 3 NOVA-2 trial, we are enrolling an outpatient, open label trial (NOVA-3) to accrue the requisite safety population required to support NDA submission as well as other clinical trials and non-clinical studies typically required by FDA for an NDA approval.

Previous wording

We are also planning to conduct a Phase 2 clinical trial evaluating LB-102 as an adjunctive treatment in major depressive disorder (“aMDD”). Additional pipeline expansion is planned for LB-102 in new indications with strong mechanistic rationale and validating clinical and real-world experience from amisulpride, potentially including negative symptoms of schizophrenia (with potential for trial initiation in the second half of 2027, subject to regulatory feedback and other factors) and Alzheimer’s disease agitation/psychosis. We are also developing a long-acting injectable (“LAI”) formulation of LB-102, which may improve adherence, a common issue in patients with schizophrenia and bipolar disorder. LB-102 is a new chemical entity and a methylated derivative of amisulpride, a second-generation antipsychotic drug approved in over 50 countries. Amisulpride is not available in the United States because the development and regulatory requirements of the U.S. Food and Drug Administration (“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 and approximately 20% are for mood disorders and the remainder are for anxiety and a variety of other indications.

Based on ongoing engagement with FDA about a trial in predominantly negative symptoms of schizophrenia, we expect to provide an update about a potential trial design in the first quarter of 2027. We are also developing a long-acting injectable (“LAI”) formulation of LB-102, which may improve adherence, a common issue in patients with schizophrenia and bipolar disorder. LB-102 is a new chemical entity and a structural modification of amisulpride, a second-generation antipsychotic drug approved in over 50 countries. Amisulpride is not available in the United States because the development and regulatory requirements of the U.S. Food and Drug Administration (“FDA”), for amisulpride were incompatible with patent coverage on the drug.

Previous wording

We designed LB-102 to address the limitations of amisulpride with the aim of creating a product candidate with the potential for a differentiated therapeutic profile and strong intellectual property protection. We believe LB-102’s mechanism of action, data from our recently completed Phase 2 trial (NOVA-1) of LB-102 in acute schizophrenia, and the heritage of clinical and real-world experience with amisulpride support the continued development of LB-102 in both psychosis and mood disorders. We believe that LB-102, if approved, can become a mainstay of psychiatric practice by offering a potentially attractive alternative to branded and generic therapeutics for the treatment of schizophrenia, bipolar depression, adjunctive MDD and other neuropsychiatric diseases, given the compelling balance of clinical activity and tolerability observed to date.

Previous wording

The U.S. market for branded antipsychotic drugs was approximately $12 billion as of 2025. Antipsychotics that have expanded beyond schizophrenia into mood disorder indications have realized substantial increases in revenue. Despite the widespread use of generic antipsychotic drugs, several of these branded drugs each generate U.S. sales greater than $1 billion annually, with some approaching between $2 billion to $4 billion in annual U.S. sales. Additionally, while available therapeutics to treat schizophrenia, bipolar depression, MDD, and other neuropsychiatric diseases demonstrate clinical benefit, a significant unmet need remains for a treatment that delivers a more favorable risk–benefit profile by balancing tolerability with rapid onset and sustained, clinically meaningful efficacy with once-daily dosing. This includes addressing – across both psychosis and mood disorders – persistent residual symptoms such as anhedonia and cognitive impairment that continue to impact functioning despite available therapies, underscoring the opportunity for improvement in the management of these conditions.

Previous wording

Since our inception in 2015, we have devoted substantially all of our resources to the research and development of LB-102 by conducting clinical trials and preclinical studies and recruiting management and technical staff to support these operations. To date, we have funded our operations primarily through the aggregate gross proceeds of approximately $549.5 million from the sales of our redeemable convertible preferred stock, common stock, convertible notes, the proceeds of our initial public offering (“IPO”) and proceeds from our private placement. On September 12, 2025, we closed the IPO and issued 21,850,000 shares of common stock at a price to the public of $15.00 per share, including 2,850,000 shares issued upon the exercise in full of the underwriters’ over-allotment option to purchase additional shares. We received gross proceeds of $327.8 million. Net proceeds were $302.3 million, after deducting underwriting commissions and other offering costs totaling $25.4 million. In February 2026, we received gross proceeds of approximately $100.0 million from our private placement. Net proceeds were approximately $93.7 million, after deducting financial advisory and other financing costs. In July 2026, we completed a private placement financing resulting in total gross proceeds of $150.0 million before deducting any transaction-related expenses.

Previous wording

We will not generate any revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for one or more of our product candidates. If we obtain regulatory approval for any of our product candidates, we expect to incur significant expenses related to developing our internal commercialization capability to support product sales, marketing, and distribution. As a result, we will need substantial additional funding to support our operating activities as we advance our product candidates through clinical development, seek regulatory approval, and prepare for and, if any of our product candidates are approved, proceed to commercialization. Until such time, if ever, as we can generate substantial revenue from product sales to support our cost structure, we expect to finance our operating activities through a combination of public or private sales of equity, government or private party grants, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. Adequate funding may not be available to us on acceptable terms, or at all.
