FDA approves Basaglar, the first follow-on insulin glargine product to treat diabetes

Basaglar is the first insulin product approved through an abbreviated approval pathway under the Federal Food, Drug, and Cosmetic Act. A 505(b)(2) application was submitted for Basaglar that relied, in part, on the FDA’s finding of safety and effectiveness for Lantus(insulin glargine injection) to support approval. The applicant demonstrated that Basaglar was sufficiently similar to Lantus to scientifically justify reliance, and also provided Basaglar-specific data to establish the drug’s safety and efficacy for its approved uses. The Basaglar-specific data included two clinical trials enrolling 534 and 744 patients with type 1 and 2 diabetes mellitus respectively.

Dosing of Basaglar should be individualized based on the patient’s needs. Basaglar is administered subcutaneously once daily at any time of day, but at the same time every day.

Basaglar should not be used during episodes of hypoglycemia (low blood sugar) or in patients with hypersensitivity to insulin glargine or one of its ingredients. Basaglar KwikPens must never be shared between patients, even if the needle is changed. Sharing poses a risk for transmission of blood-borne pathogens.

Patients or caregivers should monitor blood glucose in all patients treated with insulin products. Insulin regimens should be modified cautiously and only under medical supervision. Basaglar may cause low blood sugar (hypoglycemia), which can be life-threatening. Patients should be monitored more closely with changes to insulin dosage, co-administration of other glucose-lowering medications, meal pattern, physical activity and in patients with renal impairment or hepatic impairment or hypoglycemia unawareness.

Severe, life-threatening, generalized allergic reactions, including anaphylaxis, or generalized skin reactions, angioedema, bronchospasm, hypotension and shock may occur with any insulin.

The most common adverse reactions associated with Basaglar in clinical trials were hypoglycemia, allergic reactions, injection site reactions, pitting at the injection site (lipodystrophy), itching, rash, edema (fluid retention) and weight gain.

Basaglar received tentative approval  from the FDA on Aug. 18, 2014, and is now being granted final approval. Basaglar is not approved as a biosimilar product. No insulin glargine products are currently licensed under the Public Health Service Act, so there is no “reference product” for a proposed biosimilar product.

Basaglar is manufactured by Eli Lilly and Company in Indianapolis, Indiana.
