Here are 1-2 brief analogies to describe Lexicon Pharmaceuticals (LXRX):

• Acadia Pharmaceuticals, but for heart failure drugs. (Like Acadia, Lexicon is a biopharma company primarily focused on commercializing a single key approved drug, Inpefa, for a specific therapeutic area.)
• Esperion Therapeutics, but focused on heart failure treatments. (Similar to Esperion, Lexicon is a smaller biopharma company with an approved product in the cardiometabolic space, working to establish its market presence against larger competitors.)

• Inpefa (sotagliflozin): An oral dual SGLT1 and SGLT2 inhibitor approved to reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent heart failure visits in adults with heart failure.

Lexicon Pharmaceuticals (LXRX) sells primarily to other companies, specifically major wholesale pharmaceutical distributors in the United States.

While Lexicon's financial filings refer to these as "major wholesale pharmaceutical distributors" without explicitly naming them, industry practice and the market landscape indicate that their primary customers are typically the largest pharmaceutical wholesalers. Based on their 2023 10-K filing, Lexicon commenced commercialization of its drug INPEFA® in the U.S. in the third quarter of 2023 and sold the product to three major wholesale pharmaceutical distributors. One distributor accounted for approximately 75% of gross product sales, and another accounted for approximately 25% of gross product sales for the year ended December 31, 2023.

The major customer companies for Lexicon Pharmaceuticals are likely:

• McKesson Corporation (MCK)
• Cencora, Inc. (formerly AmerisourceBergen Corporation) (COR)
• Cardinal Health, Inc. (CAH)

• WuXi AppTec Co., Ltd. (603259.SS, 2359.HK)

The overwhelming market dominance and entrenched positions of existing, highly effective SGLT2 inhibitors (such as Jardiance and Farxiga) present a clear emerging threat to Lexicon Pharmaceuticals. This strong competitive landscape severely hinders the commercial adoption and market penetration of Lexicon's Inpefa (sotagliflozin) for heart failure, as Inpefa struggles to establish meaningful differentiation and capture significant market share against these well-established, broadly indicated, and aggressively marketed alternatives. This dynamic threatens the commercial viability of Lexicon's primary revenue-generating product and its long-term financial stability.

Lexicon Pharmaceuticals (LXRX) has several main products and pipeline candidates with the following addressable market sizes:

• INPEFA (sotagliflozin) for Heart Failure: The addressable market in the U.S. for chronic heart failure was approximately USD 5.5 billion in 2023. Approximately 6.7 million Americans suffer from heart failure, a figure projected to increase to 8 million by 2030.
• Pilavapadin (LX9211) for Diabetic Peripheral Neuropathic Pain (DPNP): The global market for DPNP is valued at USD 3.6 billion.

Lexicon Pharmaceuticals' sotagliflozin was rejected by the FDA for Type 1 diabetes in the U.S., and the company has halted launch preparations for this indication.

For LX9851 for obesity and associated cardiometabolic disorders, Lexicon has entered into a licensing agreement with Novo Nordisk for its development, manufacture, and commercialization in all indications. As this product is in preclinical/IND stage and licensed out, a specific addressable market size directly attributable to Lexicon for this product is not readily available.

Lexicon Pharmaceuticals (LXRX) is anticipated to drive future revenue growth over the next two to three years through several key initiatives and product advancements:

1. Increased Sales and Global Expansion of INPEFA (sotagliflozin) for Heart Failure: Lexicon's INPEFA, an oral inhibitor for heart failure, is a significant revenue contributor, with US sales reported at $1.0 million in Q3 2025. Further growth is expected through expanded commercialization efforts by its licensee, Viatris, which is pursuing regulatory approvals and launching sotagliflozin in markets outside the U.S. and Europe, including a first commercial order shipped to the United Arab Emirates. Additionally, ongoing clinical trials like the SONATA Phase 3 study for sotagliflozin in hypertrophic cardiomyopathy (HCM) could broaden its market and indications.
2. Milestone Payments and Royalties from LX9851 Licensing Agreement with Novo Nordisk: A substantial driver of future revenue is the exclusive licensing agreement for LX9851 with Novo Nordisk, announced in March 2025. Lexicon received an upfront payment of $45 million in April 2025 and is eligible for up to $1 billion in potential development, regulatory, and sales milestone payments, along with tiered royalties on net sales. The completion of IND-enabling studies for LX9851 positions Novo Nordisk to advance it into clinical development, triggering potential near-term milestone payments.
3. Potential Re-submission and Approval of Zynquista for Type 1 Diabetes: Lexicon submitted additional data to the FDA in September 2025 to support the benefit-risk profile of Zynquista (sotagliflozin) as an adjunct to insulin for glycemic control in adults with type 1 diabetes. The company anticipates receiving written feedback from the FDA by the end of 2025 and aims for an NDA re-submission as early as 2026. A successful re-submission and subsequent approval would open up a new product revenue stream.
4. Development and Partnership Opportunities for Pilavapadin (LX9211): Pilavapadin, an oral, non-opioid drug candidate for diabetic peripheral neuropathic pain (DPNP), has shown promising Phase 2b data supporting a 10 mg dose. Lexicon plans an End-of-Phase 2 meeting with the FDA in Q4 2025 and is actively engaging with potential partners for its Phase 3 registrational trials. Any future partnership agreements could include upfront payments and development milestones, contributing to revenue growth.
