History of Lantus
- Founded: 2000
- Founders: Sanofi (internal development)
Lantus's development originated from Sanofi's research into insulin analogs, modified forms of human insulin designed to have different pharmacokinetic profiles than regular human insulin. The key innovation in Lantus was the development of insulin glargine, an insulin analog that is soluble at acidic pH but forms microprecipitates at physiological pH when injected subcutaneously. These microprecipitates dissolve slowly, releasing insulin glargine gradually over approximately 24 hours and providing a relatively flat, peakless insulin profile.
This pharmacokinetic profile was a significant advance over the intermediate-acting insulins (such as NPH insulin) that were the standard of care for basal insulin replacement before Lantus. NPH insulin has a pronounced peak of activity several hours after injection and a duration of action of only 12-16 hours, requiring twice-daily dosing and creating a risk of nocturnal hypoglycemia from the peak effect. Lantus's peakless, 24-hour profile allowed once-daily dosing and reduced the risk of nocturnal hypoglycemia.
The FDA approved Lantus in April 2000 for the treatment of adults with type 1 or type 2 diabetes who require basal (long-acting) insulin. The European Medicines Agency approved Lantus in June 2000. Lantus was the first long-acting insulin analog to receive regulatory approval and represented a significant advance in diabetes management.
Following its approval, Lantus was rapidly adopted by endocrinologists and primary care physicians treating diabetes patients. The drug's once-daily dosing, peakless profile, and reduced risk of nocturnal hypoglycemia compared to NPH insulin made it a preferred basal insulin for many patients. Lantus became one of the most prescribed insulins globally and one of Sanofi's most commercially important products.
Lantus revenues grew steadily throughout the 2000s and early 2010s, reaching peak global sales of approximately $6.4 billion in 2015. At its peak, Lantus was one of the best-selling pharmaceutical products in the world and the dominant basal insulin globally. The drug's commercial success made Sanofi's diabetes franchise one of the most valuable in the pharmaceutical industry.
In anticipation of Lantus's patent expiration, Sanofi developed Toujeo (insulin glargine U-300), a higher-concentration formulation of insulin glargine (300 units/mL versus 100 units/mL for Lantus) that provides a slightly flatter and more prolonged insulin profile than Lantus. Toujeo was approved by the FDA in February 2015 and was intended to serve as a successor product to Lantus as biosimilar competition emerged.
Biosimilar competition for Lantus began in December 2016, when Eli Lilly launched Basaglar (insulin glargine-yfgn), which had been approved by the FDA in December 2015. Basaglar was the first insulin glargine biosimilar to launch in the United States and was priced at a discount to Lantus, beginning the erosion of Lantus's market share.
In July 2021, the FDA approved Semglee (insulin glargine-yfgn, Mylan/Biocon) as an interchangeable biosimilar to Lantus, the first interchangeable biosimilar insulin approved in the United States. Interchangeable status allows pharmacists to substitute Semglee for Lantus prescriptions without physician authorization in states that permit such substitution, significantly increasing the competitive pressure on Lantus. In December 2022, the FDA approved Rezvoglar (insulin glargine-aglr, Eli Lilly) as a second interchangeable biosimilar insulin glargine.
The entry of biosimilar competition, combined with pricing pressure from pharmacy benefit managers and payers, significantly reduced Lantus revenues from their 2015 peak. Sanofi's diabetes revenues declined substantially in the years following the launch of Basaglar and subsequent biosimilars.
In 2023, Sanofi sold its U.S. diabetes and cardiovascular operations, including Lantus's U.S. commercial operations, to a private equity consortium, reflecting the company's strategic decision to focus on specialty care (particularly Dupixent) and vaccines rather than managing the declining Lantus franchise.

Lantus Recalls & Controversies
Lantus has maintained a strong safety record throughout its more than 20 years of clinical use, though it has faced some controversies related to cancer risk questions, biosimilar competition, and broader pharmaceutical industry challenges. These issues reflect broader challenges in the pharmaceutical market rather than specific safety or quality concerns with Lantus itself.
Cancer Risk Safety Review (2009-2011): In July 2009, the FDA issued an Early Communication About Safety of Lantus to inform the public that it was reviewing four published observational studies, three of which suggested an increased risk of cancer associated with Lantus use. The FDA reviewed these studies and determined that the evidence was inconclusive due to limitations in study design and data analysis. The FDA also reviewed results from a five-year randomized clinical trial comparing Lantus to NPH insulin, which did not show an increased risk of cancer. In December 2011, the FDA concluded that the evidence did not support an increased cancer risk with Lantus.
Biosimilar Competition and Market Share Loss: Lantus faced significant commercial challenges following the entry of biosimilar competition. The approval of multiple insulin glargine biosimilars, particularly interchangeable biosimilars that could be substituted at pharmacies without physician authorization, created substantial pricing pressure and market share erosion. These commercial challenges reflect broader pharmaceutical industry dynamics rather than product-specific issues.
Biosimilar Labeling Issues: Viatris (formerly Mylan) has faced multiple recalls of its Semglee biosimilar insulin glargine due to potential missing labels on packaging. These recalls, while affecting the biosimilar rather than Lantus itself, demonstrate ongoing quality control challenges in the insulin biosimilar market that impact the broader insulin therapy landscape.
GLP-1 Competition Impact: The emergence of GLP-1 receptor agonists such as Ozempic and Mounjaro has created structural challenges for all insulin products, including Lantus. These medications provide significant weight loss benefits in addition to glucose control, reducing the role of insulin in type 2 diabetes management and creating a fundamental shift in diabetes treatment paradigms.
Sanofi Strategic Divestment: In 2023, Sanofi sold its U.S. diabetes and cardiovascular operations, including Lantus's U.S. commercial operations, to a private equity consortium. This divestment reflected Sanofi's strategic assessment that managing the declining Lantus franchise was not aligned with its focus on specialty care and vaccines, rather than specific problems with the Lantus product itself.
Pricing and Access Controversies: Lantus's high price point during its patent-protected period generated controversy regarding patient access and healthcare system costs. The drug's annual treatment costs were criticized by patient advocacy groups and healthcare payers, particularly in markets with limited insurance coverage or government healthcare systems.
