Dulaglutide

Also known as: Trulicity, Dulaglutida

Overview

Long-acting GLP-1 receptor agonist composed of a GLP-1 analog fused to a modified IgG4 immunoglobulin Fc fragment. This fusion protein confers an extended half-life of approximately 5 days, enabling weekly administration. Approved for type 2 diabetes treatment and cardiovascular risk reduction in diabetic patients.

FDA-approved as Trulicity (2014) for type 2 diabetes treatment, including cardiovascular risk reduction in diabetic patients, demonstrated in the REWIND study.

Fusion protein (~59.7 kDa) — GLP-1 analog fused with IgG4 Fc fragment

Half-life

~5 days

Administration Route

Subcutaneous

Mechanism of Action

GLP-1 receptor agonism with glucose-dependent insulin secretion stimulation
Suppression of glucagon secretion in hyperglycemic states
Delayed gastric emptying
Appetite and caloric intake reduction via hypothalamic signaling
Improved insulin sensitivity in peripheral tissues
Cardiovascular protection with reduction of major adverse cardiovascular events (MACE)
