Look for Sanofi Insulins at Mark Cuban Cost Plus Drug Company Retail Store Partners Soon
Sanofi Aventis LLC, which is the U.S. division of the global pharmaceutical company Sanofi S.A. which happens to be headquartered in France and sells several insulin varieties in the U.S., has struggled to compete in the U.S. insulin business. For many years, Lantus was generating an overwhelming majority of the company's insulin revenues with its other products generating little sales in the U.S. That was the result of a very conscious business decision which the company had made more than 20 years ago. Now, Sanofi may be reconsidering that flawed decision.
Recall that back on March 4, 2020, on the front page of the Marketplace section of the Wall Street Journal, Sanofi cried to reporter Denise Roland that the realized price it received for its insulin had fallen, on average just over 11% in 2019, including the massive legally-exempt "rebate" kickbacks which it pays to insurers and their Pharmacy Benefit Managers (PBMs) for formulary placement (for reference see "Sanofi, Fighting Back in Insulin Price Debate, Says Its Net Prices Fell 11%" By Denise Roland, Wall Street Journal, March 4, 2020, https://www.wsj.com/articles/sanofi-fighting-back-in-insulin-price-debate-says-its-net-prices-fell-11-11583340721 [the article may be hidden behind a paywall]). However, at the time, Sanofi had effectively abandoned all marketing of prandial insulins including its proprietary rapid-acting Apidra product which received FDA approval in 2004, plus Sanofi's copy of Lilly's Humalog insulin lispro product which it had branded as Admelog.
Sanofi's Lantus sales addiction was so major that in 2015, Sanofi introduced a very high concentration version of glargine in 300 units/mL potency which it branded as Toujeo; a product which was aimed primarily at patients with clinical insulin resistant Type 2 diabetes. However, to its credit, Sanofi did give the high-potency version a unique trade-name which I think does a better job of minimizing risk of pharmacy and patient errors. The same is NOT true for Novo Nordisk's Tresiba, or Lilly's Humalog, which have been quietly introducing high-concentration versions (U-200 and U-300) under the same brand names.
In other words, Sanofi had really put all of its eggs in the Lantus/Toujeo insulin basket. In fact, one could argue that Sanofi only introduced Admelog in the U.S. as retribution against Lilly for introducing Basaglar a year earlier (Basaglar was Lilly's first copy of Sanofi's Lantus which was approved in 2016 as a "follow-on" biologic; Lilly subsequently introduced a second copy of Lantus it calls Rezvoglar which was approved by FDA in 2022 as a biosimilar, which then went on to attain the FDA "interchangeable" designation on November 18, 2022). In spite of an early, promising start to Admelog sales (which was enabled largely by the company's $35/vial manufacturer coupons which remain available, although Admelog sales stopped growing once Lilly further cut prices of its own unbranded Insulin Lispro Injection product by an additional 40%), the PBM demands for rebates had kind of curtailed Admelog sales growth after 2022.
In 2022, Sanofi eventually joined Lilly and Novo Nordisk's move which had started back in 2019 when they each introduced "unbranded" versions of their bestselling insulin products as a way to counteract the PBM price inflation when Sanofi introduced Winthrop by Sanofi Insulin Glargine Injection (rDNA origin, 100 units/mL) in 2022. I blogged about that when it happened, see my post at https://blog.sstrumello.com/2022/06/sanofi-joins-ranks-of-35vial-insulin.html for more). That product was more than 70% cheaper than brand-name Lantus. However, note that Lilly and Biocon's copies of Lantus are merely the first few copies of Lantus to hit the market. A whole bunch more copies of Lantus from Sandoz, Amphastar Pharmaceuticals, Lannett Company, Civica's CivicaScript unit, and a few years from now, another from Meitheal Pharmaceuticals are all expected to potentially hit the market, which would render insulin glargine as the most-copied insulin in the U.S. when all of the dust settles. That would mean that insulin glargine products from different manufacturers could soon become commoditized where lowest price wins. I would not be surprised if we could someday see private-label versions of insulins sold under the CVS, Walgreens or even Kroger Pharmacy retailer names when so much competition exists.
Of course, in March 2024, Lilly, Novo Nordisk and Sanofi all collectively announced they would be abandoning the rebate-contracting sales model promoted by the major PBMs for the insulin therapeutic class of drugs, and each has slashed the list prices on their top selling insulins by more than 70%. In Germany, where Sanofi's insulin began shortly after the discovery of insulin made by a company then known as Hoechst, it also sold a line of biosynthetic "human" insulins under the brand-name "Insuman", although it never sold Regular or Isophane/NPH in the because Lantus had become its sole revenue-generator. The Insuman brand of insulin products was discontinued in the UK market in 2023, although it may still exist in Germany and Austria.
Naturally, Sanofi's basal insulins including Lantus, and its unbranded version of Lantus sold by its Winthrop business unit called Insulin Glargine Injection 100 units/mL, as well as a very high concentration version of glargine in 300 units/mL potency branded as Toujeo remain for sale. But on the prandial insulin front, Sanofi still sells its proprietary Apidra (insulin glulisine, 100 units/mL) which has been FDA approved since 2004, but it also sells its copy of Lilly's Humalog (insulin lispro, 100 units/mL) which was approved as a follow-on biologic on December 11, 2017, and most recently, on February 14, 2025 Sanofi also received FDA approval to sell a copy of Novolog (insulin aspart, 100 units/mL) which was approved as a biosimilar (catch my coverage at https://blog.sstrumello.com/2025/02/fda-approves-merilog-insulin-aspart.html for more).
This also means that for the moment, Sanofi is the only insulin manufacturer which sells insulin glargine, glulisine, lispro and aspart. In other words, Sanofi is the only manufacturer who currently makes and sells every prandial insulin molecule except for Regular in the U.S. Note that next-generation prandial insulins including Novo Nordisk's Fiasp (the name is an acronym for "Faster Insulin Aspart") is essentially Novolog with the addition of Niacinamide [vitamin B3] added to the buffer solution, while Lilly's next-generation prandial insulin branded as Lyumjev is insulin lispro (Humalog) with the addition of citrate and treprostinil in the buffer solution. In other words, neither Fiasp nor Lyumjev are fundamentally new insulin molecules, just slightly expedited ADME profiles thanks to some additives included in the liquid. That's also why those products are really not too much faster than the originals.
However, the fact that Sanofi even applied for FDA approval to sell a copy of Novolog (branded as Merilog) suggests that Sanofi views business opportunity in biosimilar insulins. In Europe, biosimilars are a major part of Sanofi's insulin sales, and evidently, the company sees the same potential in the U.S. In some ways, it was a learning experience to understand how applying for a biosimilar is approved with the FDA compared to the old approval method.
Lilly has done the exact same thing since biosimilars became a thing when its second copy of Sanofi's Lantus branded as Rezvoglar hit the market on April 1, 2023. Novo Nordisk is the only major insulin supplier which has yet to introduce any biosimilars, hence that company has no experience with the comparatively new approval process at the U.S. Food and Drug Administration (FDA).
It now looks as if Sanofi is also about to start selling its insulin products via Mark Cuban Cost Plus Drug Company https://www.costplusdrugs.com/medications/ (MCCPDC) with its low prices and fixed, 15% markup. While the website says that Sanofi insulin "isn't currently available on the CostPlus platform", if you search for the names of say Apidra or Lantus, all of the Sanofi insulins now appear. Some may recall that MCCPDC had initiated a trial introduction of Lilly Insulin Lispro (the unbranded version of Humalog), but the trial ended about a year later. I believe that was about the time when it introduced an innovation known as the "Team Cuban Card" https://www.teamcubancard.com/.
MCCPDC has been expanding its retail footprint nationwide via the Team Cuban Card which it says is now accepted at most national grocery chain pharmacies as well as various other independent pharmacies as well. Where I live, that would be my local Stop & Shop Pharmacy. Maybe it's a Kroger Pharmacy near you, or a Safeway Pharmacy, or a Vons Pharmacy or a Ralphs Pharmacy or a Meijer Pharmacy where you happen to live. Team Cuban Card enables patients to get a discount card in their own name (there is no charge, but they require each patient to have their own card), and you can enjoy the lower prices which MCCPDC is known for. Team Cuban Card also enables people to buy their insulin at a local pharmacy without having to rely on shipping via UPS or FedEx, which is often problematic during the summer months when insulin (even with ice-packs in the packaging) can sometimes destroy insulin thanks to packages sitting in warehouses at temperatures of more than 100 degrees Fahrenheit for a number of hours, which can literally cook your insulin before it arrives. Thanks to retail pharmacies deliveries having temperature controls for certain medicines including insulin, the same problem seldom happens on retail pharmacy pick-ups.
