Lexicon Pharmaceuticals, Inc. (NASDAQ:LXRX) - Biotech Firm Poised for Growth with Promising Pipeline and Approved Drug

Published on September 24, 2024 | Ticker: LXRX

Lexicon Pharmaceuticals, Inc. (NASDAQ:LXRX) is a biopharmaceutical company with a mission to pioneer medicines that transform patients' lives. The company is currently focused on the commercialization of its approved drug, INPEFA, and the research and development of its most advanced drug candidates, including sotagliflozin and LX9211.

Business Overview

Lexicon has derived substantially all of its revenues from strategic collaborations, research and development collaborations, technology licenses, and commercial sales of its approved drug products. The company's operating results and ability to generate additional revenues are dependent on the success of its commercialization efforts, ongoing research and development programs, and its ability to secure new collaborations and licenses.

Lexicon's lead approved drug, INPEFA, is an orally-delivered small molecule drug that the company is commercializing in the United States to reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent heart failure visits in adults with heart failure or type 2 diabetes mellitus, chronic kidney disease, and other cardiovascular risk factors. The company is also pursuing regulatory approval of sotagliflozin as a treatment for type 1 diabetes.

In addition to INPEFA and sotagliflozin, Lexicon is developing LX9211 as a treatment for neuropathic pain, LX9851 as a treatment for obesity and weight management, and several other compounds from its internal drug discovery efforts.

Financials

For the full year 2023, Lexicon reported annual net income of -$177,119,000, annual revenue of $1,204,000, annual operating cash flow of -$161,897,000, and annual free cash flow of -$162,367,000.

In the first quarter of 2024, Lexicon reported revenues of $1,130,000, primarily from net sales of INPEFA. Research and development expenses for the quarter increased to $14.4 million from $12.0 million in the same period of 2023, while selling, general and administrative expenses increased to $32.1 million from $19.1 million. The company's net loss for the quarter was $48.4 million, or $0.20 per share, compared to a net loss of $31.9 million, or $0.17 per share, in the first quarter of 2023.

Lexicon ended the first quarter of 2024 with $355.6 million in cash, cash equivalents, and short-term investments, providing the company with the necessary resources to support the commercial launch of INPEFA, prepare for the potential launch of Zynquista in type 1 diabetes, and invest in its research and clinical development programs.

Outlook

For the full year 2024, Lexicon expects research and development expenses to be between $70 million and $80 million, selling, general and administrative expenses to be between $140 million and $155 million, and total operating expenses to be between $210 million and $235 million, including non-cash expenses of $18 million to $20 million for stock-based compensation, depreciation, and amortization.

INPEFA Commercial Launch

Lexicon's primary focus is on the successful commercialization of INPEFA in the United States. The company has seen encouraging results from its efforts to accelerate the adoption of INPEFA, with awareness of the drug continuing to trend positively and intention to prescribe increasing as more of the target customers are reached by the sales team and non-personal promotional efforts.

Lexicon's strategy has been to focus its in-person sales efforts on the highest volume heart failure prescribers, with nearly 80% of INPEFA script volume currently coming from the top-tier customers. The company has seen increased adoption of INPEFA among these priority segments, with adoption in the A and B segments growing by over 40% in the first quarter of 2024 compared to the fourth quarter of 2023.

While Lexicon's overall access to INPEFA has not changed considerably from the roughly 40% level as of the last quarter, the company has continued to see ongoing increases in total script volumes. Lexicon is currently engaged in the 2025 Medicare bid cycle, working with payers to secure broader coverage and formulary placement for INPEFA.

Sotagliflozin in Type 1 Diabetes

Lexicon is also preparing to resubmit its new drug application (NDA) for sotagliflozin as an adjunct to insulin therapy for the treatment of type 1 diabetes and chronic kidney disease in the middle of 2024. The company expects a 6-month review period following the resubmission.

Lexicon believes there is a significant unmet need and substantial advocacy group support for treatment to manage glycemic control for people with type 1 diabetes and chronic kidney disease. The company plans to leverage its existing infrastructure, including its access and medical teams, to support the potential launch of Zynquista in this indication.

Sotagliflozin in Hypertrophic Cardiomyopathy

Lexicon is also developing sotagliflozin as a treatment for hypertrophic cardiomyopathy (HCM) and is preparing to initiate a Phase 3 clinical trial. The company believes sotagliflozin has the potential to address key unmet needs in HCM, including symptom improvement and physical limitations, with a scientific rationale to support its development in this indication.

The proposed Phase 3 study will include both obstructive and non-obstructive HCM patients and will use the Kansas City Cardiomyopathy Questionnaire (KCCQ) as the primary endpoint, which has been validated by the FDA for non-obstructive HCM. Lexicon believes sotagliflozin could be a cost-effective treatment option for HCM patients with limited side effects and no significant added burden to healthcare providers or payers.

LX9211 for Neuropathic Pain

Lexicon is also advancing LX9211, an orally-delivered small molecule drug candidate, as a treatment for neuropathic pain. The company is conducting a Phase 2b clinical trial of LX9211 in diabetic peripheral neuropathic pain (DPNP) and has received Fast Track designation from the FDA for the development of LX9211 in this indication.

Lexicon has reported positive results from a Phase 2 clinical trial of LX9211 in DPNP and top-line results from a separate Phase 2 trial in post-herpetic neuralgia, which also demonstrated evidence of effect. The company believes LX9211 has the potential to be a first-to-market novel non-opioid therapy in the multibillion-dollar neuropathic pain market.

LX9851 for Obesity and Weight Management

Lexicon recently revealed an exciting pipeline opportunity with LX9851, a novel oral development candidate for chronic weight management. The company's preclinical data suggests that LX9851, an inhibitor of the ACSL5 target, has the potential to address the significant opportunities beyond weight loss with GLP-1 receptor agonists, including reducing body fat while sparing lean muscle mass and improving metabolic profile.

Lexicon has already received significant interest from potential partners regarding LX9851 and its ACSL5 target. The company is currently conducting IND-enabling studies and plans to advance LX9851 into clinical development.

Risks and Challenges

Lexicon faces several risks and challenges, including the successful commercialization of INPEFA, the ability to obtain regulatory approval for sotagliflozin in type 1 diabetes and other indications, the successful development and commercialization of its pipeline candidates, and the ability to secure new collaborations and licenses to generate additional revenues.

The company also faces competition from other pharmaceutical companies, including AstraZeneca and Eli Lilly, which market SGLT inhibitors that compete with INPEFA in the heart failure market. Additionally, Lexicon's operating results have fluctuated in the past and are likely to continue to do so, making period-to-period comparisons less indicative of future performance.

Conclusion

Lexicon Pharmaceuticals is a biopharmaceutical company with a promising pipeline and an approved drug, INPEFA, that is currently being commercialized in the United States. The company's focus on the successful launch of INPEFA, the potential approval and launch of Zynquista in type 1 diabetes, and the development of its pipeline candidates, including sotagliflozin in HCM and LX9211 for neuropathic pain, position Lexicon for potential growth in the coming years. With a strong balance sheet and a talented management team, Lexicon appears well-positioned to navigate the challenges and capitalize on the opportunities in the biopharmaceutical industry.
