•We are developing pilavapadin (LX 9211), an orally-delivered small molecule drug candidate, as a treatment for neuropathic pain. We have completed three Phase 2 clinical trials evaluating the safety and tolerability of pilavapadin and its effects on diabetic peripheral neuropathic pain, or DPNP, and neuropathic pain. We have reported top-line results from our Phase 2b clinical trial of pilavapadin in DPNP, which demonstrated clear evidence of effect at the 10 mg dose, and have received Fast Track designation from the U.S. Food and Drug Administration, or FDA, for development of pilavapadin in that indication. We have also reported positive results from a Phase 2a clinical trial of pilavapadin in DPNP and results from a separate Phase 2a clinical trial of pilavapadin in post-herpetic neuralgia which also demonstrated evidence of effect.

Previous wording

Our ability to secure future revenue-generating agreements will depend upon our ability to address the needs of our potential future collaborators and licensees, and to negotiate agreements that we believe are in our long-term best interests. We may determine, as we have with INPEFA in heart failure in the United States, that our interests are better served by retaining rights to our discoveries and advancing our therapeutic programs to a later stage, which could limit our near-term revenues and increase expenses. Because of these and other factors, our operating results have fluctuated in the past and are likely to do so in the future, and we do not believe that period-to-period comparisons of our operating results are a good indication of our future performance.

Because of these and other factors, our operating results have fluctuated in the past and are likely to do so in the future, and we do not believe that period-to-period comparisons of our operating results are a good indication of our future performance.

Previous wording

Revenues were approximately $28.9 million and $1.6 million, respectively, for the three months ended June 30, 2025 and 2024 and $30.1 million and $2.8 million, respectively, for the six months ended June 30, 2025 and 2024. Revenues for 2025 included $27.5 million in licensing revenue recognized from the Novo Nordisk licensing agreement. See Note 5, Collaborations and Strategic Alliances, for further information. Total revenues for each of the periods presented also include product revenues from sales of INPEFA.

Current wording

Revenues were approximately $14.2 million and $1.8 million, respectively, for the three months ended September 30, 2025 and 2024 and $44.3 million and $4.5 million, respectively, for the nine months ended September 30, 2025 and 2024. Revenues for the three months and nine months ended September 30, 2025 included $13.2 million and $40.7 million in licensing revenue recognized from the Novo Nordisk licensing agreement. See Note 5, Collaborations and Strategic Alliances, for further information. Total revenues for each of the periods presented also include product revenues from sales of INPEFA.

Previous wording

Cost of sales during the three and six months ended June 30, 2025 and 2024 were less than $0.2 million and primarily consist of third-party manufacturing costs and freight associated with sales of INPEFA. Prior to receiving regulatory approval of INPEFA in May 2023, we had completed or begun the manufacturing of certain INPEFA raw materials. These raw materials were either received at “zero-cost” to us in conjunction with a terminated agreement in 2019 or recorded as research and development expense. Based on our expectations for future manufacturing costs, we estimate these amounts totaled approximately $39.0 million. We began capitalizing inventory manufactured subsequent to regulatory approval of INPEFA as the related costs were expected to be recoverable through the commercialization of the product. At June 30, 2025, substantially all of the “zero-cost” INPEFA raw materials remains available to us. However, the time period over which this inventory is consumed will depend on a number of factors, including the amount of future INPEFA sales, use of this inventory to satisfy manufacturing and supply agreements associated with strategic alliances (for further information, see our Annual Report on Form 10-K for the year ended December 31, 2024) or in clinical development or other research activities, production lead times, and/or the ability to utilize inventory prior to its expiration date. Any future sales of INPEFA will utilize this “zero-cost” inventory and will result in a lower average per unit cost of materials during that period. We estimate our cost of goods sold as a percentage of net product revenue will be less than 10% subsequent to the utilization of all of the remaining “zero-cost” inventory.
