HUMALOG® (insulin lispro) 100 units/mL: Biosimilarity to Admelog® (insulin lispro) 100 units/mL

Admelog (insulin lispro) is not considered biosimilar to Humalog (insulin lispro) in the United States.


Detailed Information

Sanofi-Aventis in 2017, received FDA approval for Admelog® (insulin lispro injection) 100 units/mL via an abbreviated pathway as a follow-on biologic. The Admelog new drug application allowed the FDA to consider the safety and efficacy of Humalog® (insulin lispro injection) 100 units/mL as the relied upon listed drug and two phase 2 clinical trials specific to Admelog. In March 2020, all insulins were transitioned from drugs to biologics and due to regulatory definitional differences, Admelog is not considered a biosimilar in the United States.

Lilly has not investigated Admelog. The best source of information for any product is its manufacturer. Therefore, please refer to Sanofi-Aventis for questions specific to Admelog.

It is important to talk to your health care provider if you are unsure about your current prescribed dose of insulin. He/she is in the best position to discuss your insulin dose as he/she has access to your medical records. If your health care provider has questions or needs additional information about Humalog, please have him/her contact Lilly at 1-800-Lilly-Rx (1-800-545-5979).
