THE WOODLANDS, Texas, Aug. 06, 2026 (GLOBE NEWSWIRE) — Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX), today reported financial results for the three months ended June 30, 2026, and provided an update on key corporate milestones and accomplishments. 

“Lexicon continued to make strong progress during the second quarter, with the refinement of our strategy and sharpening of our focus beginning to bear fruit across our business,” said Mike Exton, Ph.D., Lexicon’s chief executive officer and director. “Among all the accomplishments, I’m particularly pleased that we have completed enrollment of our SONATA-HCM study on time, reflecting strong clinical interest for a novel class of medicine to treat HCM. Overall, I could not be more confident in how these opportunities are poised to shape the company over the coming months.”

“We remain very focused on disciplined, targeted capital allocation as we continue to advance our clinical programs,” said Scott Coiante, Lexicon’s chief financial officer. “With early commercial planning now underway for our late-state pipeline, we are committed to maximizing the value of these opportunities to create long-term shareholder value.”

Second Quarter 2026 Business and Pipeline Highlights 

Cardiometabolic

Sotagliflozin
Sotagliflozin is a unique oral inhibitor of sodium-glucose cotransporter types 1 and 2 (SGLT1 and SGLT2) and has been studied in approximately 20,000 patients across multiple cardiometabolic indications. Sotagliflozin is commercially available in the U.S. for heart failure as INPEFA^®.

Hypertrophic Cardiomyopathy (HCM)

• Enrollment has been completed in SONATA-HCM, a pivotal Phase 3 placebo-controlled study, substantially exceeding its enrollment target of 500 patients across both non-obstructive (nHCM) or obstructive HCM (oHCM). 
• The primary efficacy endpoint will assess improvement in symptoms for the entire population (nHCM and oHCM). The final study population included a substantial majority of patients with nHCM, providing a robust opportunity to evaluate sotagliflozin in a patient group for whom effective treatment options remain limited, as well as a meaningful cohort of patients with oHCM.
• Lexicon continues to expect topline results in the first quarter of 2027.

Type 1 Diabetes (T1D) (ZYNQUISTA^®)

• Lexicon remains focused on bringing ZYNQUISTA to market for glycemic control in adults with T1D, a patient population for which there are no treatment options beyond insulin.
• STENO1, a third-party funded, investigator-initiated study of sotagliflozin being conducted by the STENO Diabetes Center (Denmark) is approaching the patient exposure and safety data requirements previously identified by the U.S. Food and Drug Administration (FDA) as being adequate to support a resubmission of the company’s New Drug Application (NDA), which Lexicon anticipates will occur in the fourth quarter of 2026 based on current estimated timing of data collection.
• The safety data received to date from this open-label trial continue to support the resubmission.

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

• Lexicon continues to support licensee Viatris in its regulatory filing and commercial strategy for sotagliflozin outside of the U.S. and Europe.
• Viatris has obtained regulatory approval for heart failure in the United Arab Emirates and Bahrain and has submitted applications for regulatory approval for heart failure in several other markets, including Saudi Arabia, Canada, Australia, New Zealand, Mexico, Singapore, Oman, Thailand, Turkey, Malaysia, Philippines, and Kuwait. Viatris anticipates regulatory decisions in Australia and Canada and regulatory submissions in other markets in 2026.

LX9851 
LX9851 is a first-in-class, non-incretin, oral, small molecule inhibitor of acyl-CoA synthetase 5 (ACSL5) in development by licensee Novo Nordisk for obesity and associated metabolic disorders.

Obesity and Associated Cardiometabolic Disorders

• In March 2026, Novo Nordisk initiated a Phase 1 study investigating single and multiple ascending doses of LX9851 compared to placebo in overweight or obese people. The Phase 1 program is expected to be completed in the first quarter of 2027.
• Under the terms of Lexicon’s exclusive license agreement with Novo Nordisk, Lexicon received an upfront payment of $45 million and two $10 million payments related to clinical development. Lexicon is eligible to receive a third $10 million milestone payment as early as later this year and up to an aggregate of $1 billion in upfront and development, regulatory and sales milestone payments. Lexicon is also eligible for tiered royalties on net sales of LX9851.

Pilavapadin (LX9211)

Discovered using Lexicon’s unique approach to gene science and target identification, pilavapadin is a potent, once-daily, orally delivered, selective, investigational small molecule inhibitor of AAK1. Lexicon identified AAK1 in its target discovery efforts as a promising approach for the treatment of neuropathic pain and is exploring its potential in other indications.   

Diabetic Peripheral Neuropathic Pain (DPNP)

• Pilavapadin has the potential to be the first oral, non-opioid drug therapy approved in neuropathic pain in more than 20 years.
• Lexicon continues to explore strategic opportunities to maximize the global potential of this investigative therapy.

Second Quarter 2026 Financial Highlights

Revenues: Total revenues were $0.7 million for the second quarter of 2026, consisting of net sales of INPEFA.

Total revenues for the second quarter of 2025 were $28.9 million, consisting of $27.6 million in licensing revenue recognized from the Novo Nordisk licensing agreement and $1.3 million from net sales of INPEFA.

Research and Development (R&D) Expenses: Research and development expenses for the second quarter of 2026 increased to $17.4 million from $15.7 million for the corresponding period in 2025, reflecting higher external research expense in 2026 related to the Company’s ongoing SONATA-HCM Phase 3 clinical trial.

Selling, General and Administrative (SG&A) Expenses: Selling, general and administrative expenses for the second quarter of 2026 increased to $9.8 million from $9.4 million for the corresponding period in 2025. The increase in 2026 reflects higher professional and consulting costs.
