HOW SHOULD NPH BE CONVERTED TO LEVEMIR?

A

HOW SHOULD NPH BE CONVERTED TO LEVEMIR? If converting from NPH insulin, the change can be done on a unit-to-unit basis. However, some patients with type 2 diabetes may require more LEVEMIR than NPH insulin, as observed in one trial [see Clinical Studies (14)]. Doses and timing of concurrent rapid-acting or short-acting insulins or other concomitant antidiabetic treatment may need to be adjusted.

Q

WHAT WAS THE IMPACT OF ANTIBODIES ON GLUCOSE CONTROL IN THE LEVEMIR CLINICAL TRIALS?

A

WHAT WAS THE IMPACT OF ANTIBODIES ON GLUCOSE CONTROL IN THE LEVEMIR CLINICAL TRIALS? All insulin products can elicit the formation of insulin antibodies. These insulin antibodies may increase or decrease the efficacy of insulin and may require adjustment of the insulin dose. In phase 3 clinical trials of LEVEMIR, antibody development has been observed with no apparent impact on glycemic control.

Q

HOW CAN LEVEMIR BE DESCRIBED? (ROUTE OF ADMINISTRATION, DURATION OF ACTION).

A

HOW CAN LEVEMIR BE DESCRIBED? (ROUTE OF ADMINISTRATION, DURATION OF ACTION). LEVEMIR (insulin detemir [rDNA origin] injection) is a sterile solution of insulin detemir for use as a subcutaneous injection. Insulin detemir is a long-acting (up to 24-hour duration of action) recombinant human insulin analog. LEVEMIR is produced by a process that includes expression of recombinant DNA in Saccharomyces cerevisiae followed by chemical modification.

A

Insulin-naïve patients with type 2 diabetes who are not achieving glycemic targets on OADs alone can begin treatment with Levemir® at 10 U once or twice daily.

48
Q

The adverse events observed with Levemir® are comparable to those observed with any insulin therapy.

50
Q

Compare the incidence of severe hypoglycemia in patients on Levemir to NPH for Type 1 and Type 2 diabetes.

A

The incidence of severe hypoglycemia was similar for both Levemir® and NPH in patients with type 1 or type 2 diabetes

51
Q

Levemir® may be used in pediatric patients starting at what age?

A

Levemir® may be used in pediatric patients with type 1 diabetes ≥6years of age.

52
Q

To create Levemir®, what was modified?

A

To create Levemir®, the B30 threonine in human insulin was removed, and a 14-carbon (C-14) fatty acid chain was attached to amino acid B29.

53
Q

The long-acting effects of Levemir® are due to:

A

Slow absorption from the SC injection site and its binding to albumin in the bloodstream. When Levemir® is injected just under the skin, it forms a depot of insulin that is absorbed slowly into the bloodstream over a period of up to 24hours.

54
Q

Injection of Levemir® resulted in higher AUC levels in:

A

Injection of Levemir® resulted in higher AUC levels in children and elderly patients in comparison to adolescents and adults.

55
Q

To obtain FDA approval, the studies cited in the PI were designed to show:

A

Equal efficacy (noninferiority) rather than greater efficacy (superiority).

56
Q

Treatments with Levemir®, NPH, and insulin glargine (rDNA origin) injection (Lantus®) have been compared in efficacy and safety studies. What was the difference in efficacy?

A

The efficacy of all three insulins in reducing A1C levels was comparable, with no clinically relevant differences. Treatments with Levemir®, NPH, and insulin glargine (rDNA origin) injection (Lantus®) have been compared in efficacy and safety studies. Levemir® and NPH were administered either once or twice daily, while insulin glargine was administered only once daily. A1C levels were used to evaluate glycemic control.

57
Q

Studies A and B used NovoLog® as the bolus insulin, and Study C used regular human insulin for bolus doses. Study A compared the A1C and FPG values of treatment with Levemir® to that of NPH as basal insulin; similarly, Study C compared the A1C values following treatment with Levemir® or NPH. Study B compared the A1C values following treatment with Levemir® or insulin glargine. What results for efficacy were observed?

A

Results from all three studies demonstrated comparable reductions in A1C for Levemir®, NPH, and insulin glargine.

58
Q

Study D in the PI, corresponds to the Robertson study. Levemir® and NPH were evaluated in a basal-bolus regimen for pediatric patients with type 1 diabetes. What were the results of the study?

A

A1C reductions in patients treated with Levemir® were comparable to those seen in patients treated with NPH.

59
Q

Study E, corresponds to the Hermansen study. In this treat-to-target trial, glycemic response was evaluated in adult patients with type 2 diabetes. The basal insulin, either Levemir® or NPH, was administered twice daily in combination with OADs. What were the results of the study?

A

Levemir® and NPH were effective enough to help a majority of patients, 70% and 74%, respectively, reach that goal.

60
Q

Study F corresponds to the Raslova study. Glycemic control was evaluated from a basal-bolus treatment with either Levemir® plus NovoLog® or NPH plus regular human insulin. How does LEVEMIR compare to NPH?

A

Levemir® demonstrated A1C and FPG reductions similar to those of NPH.

61
Q

The results from Studies E and F suggest what?

A

Levemir® effectively controls glucose levels in adults with type 2 diabetes as part of a basal-bolus treatment or as an add-on insulin to OAD therapy.
