Symlin (Pramlintide Acetate Subcutaneous) - Summary



SYMLIN is used with insulin and has been associated with an increased risk of insulin-induced severe hypoglycemia, particularly in patients with type 1 diabetes. When severe hypoglycemia associated with SYMLIN use occurs, it is seen within 3 hours following a SYMLIN injection. If severe hypoglycemia occurs while operating a motor vehicle, heavy machinery, or while engaging in other high-risk activities, serious injuries may occur. Appropriate patient selection, careful patient instruction, and insulin dose adjustments are critical elements for reducing this risk.



(pramlintide acetate) Injection

Rx only

SYMLIN® (pramlintide acetate) Injection is an antihyperglycemic drug for use in patients with diabetes treated with insulin. Pramlintide is a synthetic analog of human amylin, a naturally occurring neuroendocrine hormone synthesized by pancreatic beta cells that contributes to glucose control during the postprandial period. Pramlintide is provided as an acetate salt of the synthetic 37-amino acid polypeptide, which differs in amino acid sequence from human amylin by replacement with proline at positions 25 (alanine), 28 (serine), and 29 (serine).

SYMLIN is given at mealtimes and is indicated for:

  • Type 1 diabetes, as an adjunct treatment in patients who use mealtime insulin therapy and who have failed to achieve desired glucose control despite optimal insulin therapy.
  • Type 2 diabetes, as an adjunct treatment in patients who use mealtime insulin therapy and who have failed to achieve desired glucose control despite optimal insulin therapy, with or without a concurrent sulfonylurea agent and/or metformin.

Published Studies Related to Symlin (Pramlintide Subcutaneous)

Efficacy and harms of the hypoglycemic agent pramlintide in diabetes mellitus. [2010.11]
PURPOSE: We conducted a study to examine the efficacy, effectiveness, and harms of pramlintide as adjunct therapy in adults and children with type 1 or type 2 diabetes... CONCLUSIONS: Pramlintide was somewhat more effective than placebo as adjunct therapy for improving HbA(1c) levels and weight in adults with type 1 diabetes on conventional insulin therapy, or type 2 diabetes and inadequate glycemic control with their current therapies, with between-group differences in HbA(1c) levels in the range of 0.2% to 0.4%. Further research is needed to determine pramlintide's durability of hypoglycemic effect, as well as effects on patient-reported outcomes, morbidity, mortality, and long-term harms.

Enhanced weight loss following coadministration of pramlintide with sibutramine or phentermine in a multicenter trial. [2010.09]
Preclinical evidence suggests that pharmacotherapy for obesity using combinations of agents targeted at distinct regulatory pathways may produce robust additive or synergistic effects on weight loss. This randomized placebo-controlled trial examined the safety and efficacy of the amylin analogue pramlintide alone or in combination with either phentermine or sibutramine...

Patient reported outcomes in adults with type 2 diabetes on basal insulin randomized to addition of mealtime pramlintide or rapid-acting insulin analogs. [2010.05]
CONCLUSIONS: Adding pramlintide on a background of basal insulin improved some aspects of treatment satisfaction and quality of life relative to adding rapid-acting insulin analogs.

Comparison of the post-meal glucose response to different insulin bolus waveforms in insulin pump- and pre-meal pramlintide-treated type 1 diabetes patients. [2010.02]
BACKGROUND: Both pramlintide and insulin pump waveforms separately provide improved post-meal glucose control. However, when used together there may be a mismatch in actions leading to hypoglycemia. We studied the three currently available waveforms and a "modified combination wave" (MC) in pramlintide-treated patients. The MC was a "square" (SQ) wave combined with a "standard" (ST) bolus that was delayed 1 h into the mealtime... CONCLUSIONS: For currently available insulin pump bolus waves, SQ and MC may be least likely to cause hypoglycemia in pramlintide-treated patients.

A pilot trial of pramlintide home usage in adolescents with type 1 diabetes. [2009.11]
OBJECTIVE: The objective of this study was to evaluate the safety and efficacy of home pramlintide use in adolescents with type 1 diabetes... CONCLUSIONS: Pramlintide can help some adolescents to decrease postprandial hyperglycemia, HbA1c values, body weight, and insulin dosages. Additional large-scale trials should now be considered.

Clinical Trials Related to Symlin (Pramlintide Subcutaneous)

An Observational Study Evaluating SYMLIN® (Pramlintide Acetate) Injection Use in Insulin Using Patients With Type 2 and Type 1 Diabetes [Completed]
This is an open label, observational study designed to collect data that characterize the use of SYMLIN following the introduction of the medication into the marketplace. Health care providers and subjects selected for study participation are intended to be representative of those providers prescribing, and subjects receiving, SYMLIN therapy.

A Study to Evaluate Symlin in Adolescent Subjects With Type 1 Diabetes Mellitus [Completed]
This study will be the first evaluation of Symlin in adolescent subjects with type 1 diabetes mellitus and is designed to evaluate the blood levels (pharmacokinetics), biochemical and physiological effects (pharmacodynamics), and safety and tolerability of Symlin in these subjects.

Use of Exenatide and Pramlintide to Decrease Post-prandial Hyperglycemia [Recruiting]
The main purpose of the study is to determine the effects of 16 weeks of adjunctive pramlintide or exenatide use on glycemic control in Type 1 Diabetes.

A Study to Characterize Regimens of Basal Insulin Intensified With Either Symlin® or Rapid Acting Insulin in Patients With Type 2 Diabetes [Completed]
This will be a randomized, open label, parallel group, multicenter study. There will be two phases in the study. Phase 1 (Baseline to Week 24) will compare the efficacy and safety of regimens of basal insulin intensified with either Symlin or rapid acting insulin in patients with type 2 diabetes who have either been on a prior regimen of insulin for less than 6 months and were taking less than 50 U total of insulin per day OR are candidates for the initiation of insulin therapy. The purpose of Phase 2 (Week 24 to Week 36) is to explore further intensification of diabetes regimens in patients failing to achieve HbA1c <=6. 5% at Week 24.

A Pilot Study of Continuous Subcutaneous Pramlintide Infusion Therapy in Patients With Type 1 Diabetes [Completed]
This research project will investigate the effects of pramlintide (Symlin) given by continuous subcutaneous (under the skin) infusion throughout the day and night, along with meal doses similar to those injected during conventional pramlintide (Symlin) treatment, delivered using a second insulin pump, in subjects with inadequately controlled type I diabetes mellitus who are already using insulin pump therapy. Study participants will wear two pumps for a four month period, taking insulin in their usual manner and pramlintide (Symlin) in a similar basal/bolus fashion. Continuous glucose monitors will be worn on three occasions during the study to assess blood glucose responses to continuous pramlintide (Symlin) treatment.
