Bydureon

INDICATIONS

BYDUREON is an extended-release formulation of exenatide, administered as an injection once every 7 days (weekly).

Type 2 Diabetes Mellitus

BYDUREON is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus [see Clinical Studies].

Important Limitations Of Use

Because of the uncertain relevance of the rat thyroid C-cell tumor findings to humans, prescribe BYDUREON only to patients for whom the potential benefits are considered to outweigh the potential risk.

BYDUREON is not recommended as first-line therapy for patients who have inadequate glycemic control on diet and exercise.

BYDUREON is not a substitute for insulin. BYDUREON should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis, as it would not be effective in these settings.

The concurrent use of BYDUREON with insulin has not been studied and cannot be recommended.

BYDUREON and BYETTA® (exenatide) injection both contain the same active ingredient, exenatide, and therefore should not be used together.

Based on postmarketing data, exenatide has been associated with acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis. BYDUREON has not been studied in patients with a history of pancreatitis. It is unknown whether patients with a history of pancreatitis are at increased risk for pancreatitis while using BYDUREON. Other antidiabetic therapies should be considered in patients with a history of pancreatitis.

DOSAGE AND ADMINISTRATION

Recommended Dosing

BYDUREON (2 mg per dose) should be administered once every 7 days (weekly). The dose can be administered at any time of day, with or without meals.

Missed Dose

If a dose is missed, it should be administered as soon as noticed, provided the next regularly scheduled dose is due at least 3 days later. Thereafter, patients can resume their usual dosing schedule of once every 7 days (weekly).

If a dose is missed and the next regularly scheduled dose is due 1 or 2 days later, the patient should not administer the missed dose and instead resume BYDUREON with the next regularly scheduled dose.

Changing Weekly Dosing Schedule

The day of weekly administration can be changed if necessary as long as the last dose was administered 3 or more days before.

Administration

BYDUREON must be injected immediately after the dose is prepared. BYDUREON is administered as a subcutaneous (SC) injection in the abdomen, thigh, or upper arm region. Advise patients to use a different injection site each week when injecting in the same region. BYDUREON must not be administered intravenously or intramuscularly. BYDUREON is intended for patient self-administration.

Prior to initiation of BYDUREON, patients should be trained by their healthcare professional. For the BYDUREON Pen, study data demonstrated that training reduced the risk of administration errors such as inadequate mixing or incomplete dosing. Patients using the BYDUREON Pen should be trained on proper mixing and injection technique to ensure the product is adequately mixed and a full dose is delivered. Refer to the accompanying Instructions for Use for complete administration instructions with illustrations. The instructions can also be found at www.bydureon.com.

Changing From BYETTA To BYDUREON

Prior treatment with BYETTA is not required when initiating BYDUREON therapy. If the decision is made to start BYDUREON in an appropriate patient already taking BYETTA, BYETTA should be discontinued. Patients changing from BYETTA to BYDUREON may experience transient (approximately 2 weeks) elevations in blood glucose concentrations.
