Third Quarter 2025 Business and Pipeline Highlights 

Pilavapadin (LX9211) for Diabetic Peripheral Neuropathic Pain (DPNP)
Pilavapadin is an orally delivered, small molecule drug candidate for the treatment of DPNP, among other potential indications. Pilavapadin has the potential to be the first oral, non-opioid drug therapy approved in neuropathic pain in more than 20 years.  

• Key recent data presentation highlights include:
  • Oral presentations at the European Association for the Study of Diabetes (EASD) and NEUROdiab Annual Meetings in September 2025, demonstrating that pilavapadin 10 mg resulted in a two-point reduction from baseline in average daily pain scores (ADPS) by week 12 and was generally well tolerated in the PROGRESS Phase 2b study in DPNP.
  • Oral presentation at the Arrowhead 19th Annual Pain Therapeutics Summit in October 2025, with results from a post-hoc pooled analysis of the Phase 2 RELIEF-DPN-1 and Phase 2b PROGRESS studies supporting advancement of the 10 mg dose into Phase 3 development for DPNP.
• End-of-Phase 2 meeting scheduled with FDA during the fourth quarter of 2025 and partnership discussions are ongoing.

LX9851 for Obesity and Associated Cardiometabolic Disorders 
LX9851 is a first-in-class, non-incretin, oral, small molecule inhibitor of acyl-CoA synthetase 5 (ACSL5) in IND-enabling studies for obesity and weight management.

• In March 2025, Lexicon announced an exclusive licensing agreement for LX9851 with Novo Nordisk. Under the terms of the agreement, Lexicon received an upfront payment of $45 million in April and is eligible to receive up to $1 billion in upfront and potential development, regulatory and sales milestone payments. Lexicon is also eligible for tiered royalties on net sales of LX9851.
• Lexicon has completed all IND-enabling studies of LX9851. Our licensee Novo Nordisk is now preparing for IND submission and initiation of clinical development, which would potentially trigger up to an additional $30 million in near-term milestone payments to Lexicon.

Sotagliflozin
Sotagliflozin is an oral inhibitor of sodium-glucose cotransporter types 2 and 1 (SGLT2 and SGLT1) and has been studied in approximately 20,000 patients across multiple cardiometabolic indications.

Heart Failure (INPEFA^®)

• • Sotagliflozin is commercially available in the U.S. for heart failure as INPEFA^®.
  • Lexicon presented a post-hoc analysis of the SCORED and SOLOIST-WHF studies of sotagliflozin at the European Society of Cardiology (ESC) 2025 Congress, demonstrating that sotagliflozin provides consistent relative risk reduction in heart failure and major cardiovascular events across all age ranges, including in adults older than 75.

Hypertrophic Cardiomyopathy (HCM)

• • Enrollment continues to accelerate in SONATA-HCM, a pivotal Phase 3 placebo-controlled study with a targeted enrollment of 500 patients with obstructive or nonobstructive HCM. 
  • Lexicon has completed the initiation of 130 sites in 20 countries across the United States, Europe and Latin America.

Viatris License for All Indications Ex-U.S. and Ex-Europe

• • Lexicon has supported licensee Viatris in its regulatory filing strategy for sotagliflozin outside of the U.S. and Europe, with preparations underway by Viatris for regulatory approval submissions in a number of ex-U.S. and ex-European markets.
  • Lexicon has shipped the first commercial order of INPEFA to Viatris in the United Arab Emirates, the first country to obtain approval outside of the U.S.

Type 1 Diabetes (T1D) (ZYNQUISTA^®)

• • The Company remains focused on bringing ZYNQUISTA to market for people with T1D who have not benefitted from a new treatment in over two decades.
  • Lexicon has submitted new data to U.S. Food and Drug Administration (FDA) supporting the benefit risk profile of Zynquista in T1D. The Company is currently engaged with FDA and expects regulatory feedback in the fourth quarter of 2025 regarding a potential resubmission of its New Drug Application (NDA).

Third Quarter 2025 Financial Highlights
Revenues: Total revenues for the third quarter of 2025 increased to $14.2 million from $1.8 million for the corresponding period in 2024. Total revenues for the third quarter of 2025 consist of $13.2 million of licensing revenue derived from the Company’s licensing agreement with Novo Nordisk and $1.0 million of revenues from US sales of INPEFA. 

Research and Development (R&D) Expenses: Research and development expenses for the third quarter of 2025 decreased to $18.8 million from $25.8 million for the corresponding period in 2024, primarily reflecting lower external research expense on the PROGRESS clinical trial partially offset by increased investment in the SONATA Phase 3 clinical trial.

Selling, General and Administrative (SG&A) Expenses: Selling, general and administrative expenses for the third quarter of 2025 decreased to $7.6 million from $39.6 million for the corresponding period in 2024. The decrease in 2025 reflects lower costs as a result of the Company’s strategic repositioning in late 2024 and the significantly reduced marketing efforts for INPEFA in 2025.  

Net Loss: Net loss for the third quarter of 2025 was $12.8 million, or $0.04 per share, as compared to a net loss of $64.8 million, or $0.18 per share, in the corresponding period in 2024. For the third quarters of 2025 and 2024, net losses included non-cash, stock-based compensation expense of $3.4 million, and $2.8 million, respectively.

Cash, Investments, and Restricted Cash: As of September 30, 2025, Lexicon had $145.0 million in cash and investments including $29 million in restricted cash, as compared to $238.0 million in cash and investments as of December 31, 2024.
