Lilly Launches Rezvoglar in the US
Eli Lilly and Company has launched its insulin glargine biosimilar, Rezvoglar (insulin glargine-aglr), on the US market, making it the second interchangeable insulin biosimilar to become commercially available to American patients with diabetes.

Lilly’s KwikPen autoinjector for Rezvoglar
Rezvolgar was approved as the fourth biosimilar to receive an interchangeability designation in November 2022. It was originally approved by the FDA in December 2021. Insulin glargine products are used to improve glycemic control in adult and pediatric patients with type 1 diabetes and in adults with type 2 diabetes.
Interchangeability allows for pharmacists to substitute an insulin glargine prescription with Rezvoglar or Semglee (insulin glargine-yfgn), the first insulin glargine biosimilar to be deemed interchangeable, without having to get permission from a physician. The designation is unique to the United States and is intended to improve accessibility to biosimilars by allowing patients to get their medications faster if the one listed on their prescription is not available.
In early March, when Lilly announced that it will lower its list prices for all its insulin products, the company disclosed that Rezvolgar will launch at a 78% discount to the reference product (Lantus). The biosimilar will be available to patients for $92 for a 5-pack of KwikPens, the company’s autoinjector device.
In addition to Semglee and Lantus, Rezvoglar will compete against Basaglar, an authorized generic insulin. Authorized generic products, also known as follow-on biologics, are biosimilars by definition; however, because they were approved by the FDA prior to the installation of a biosimilars approval pathway, they are not legally considered biosimilars in the United States.
Outside of Rezvoglar, Lilly is the owner of Humulin (recombinant human insulin) and Humalog (reference insulin lispro), as well as an unbranded insulin lispro product.
From Amjevita to Zarxio: A Decade of US Biosimilar Approvals
March 6th 2025Since the FDA’s groundbreaking approval of Zarxio in 2015, the US biosimilars market has surged to 67 approvals across 18 originators—though the journey has been anything but smooth, with adoption facing hurdles along the way.
How AI Can Help Address Cost-Related Nonadherence to Biologic, Biosimilar Treatment
March 9th 2025Despite saving billions, biosimilars still account for only a small share of the biologics market—what's standing in the way of broader adoption and how can artificial intelligence (AI) help change that?
Biosimilars Fuel Price Cuts in European Insulin Glargine Markets
February 14th 2025Although Lantus continues to lead the insulin glargine market globally, the rise of biosimilars like Abasaglar and Semglee has sparked significant price reductions, with some European countries seeing discounts of up to 42.3%.
Will the FTC Be More PBM-Friendly Under a Second Trump Administration?
February 23rd 2025On this episode of Not So Different, we explore the Federal Trade Commission’s (FTC) second interim report on pharmacy benefit managers (PBMs) with Joe Wisniewski from Turquoise Health, discussing key issues like preferential reimbursement, drug pricing transparency, biosimilars, shifting regulations, and how a second Trump administration could reshape PBM practices.
The Biosimilar Void: 90% of Biologics Coming Off Patent Will Lack Biosimilars
February 5th 2025Of the 118 biologics losing exclusivity over the next decade, only 10% have biosimilars in development, meaning a vast majority of biologics have no pipeline, which limits savings potential for the health care system.
