Trulicity® (dulaglutide): Antibodies

Across 9 clinical studies, 64 (1.6%) patients treated with Trulicity (dulaglutide) developed anti-drug antibodies to dulaglutide.

Detailed Information

In 9 phase 2 and phase 3 clinical studies, treatment with dulaglutide was associated with a 1.6% incidence of treatment emergent dulaglutide anti-drug antibodies (Table 1. Incidence of Anti-Drug Antibodies Across 9 Phase 2 and Phase 3 Studies in Patients Treated With Dulaglutide), indicating that the structural modifications in the GLP-1 and modified IgG4 parts of the dulaglutide molecule, together with high homology with native GLP-1 and native IgG4, minimise the risk of immune response against dulaglutide. 1,2

Patients with dulaglutide anti‑drug antibodies generally had low titres, and although the number of patients developing dulaglutide anti‑drug antibodies was low, examination of the phase III data revealed no clear impact of dulaglutide anti‑drug antibodies on changes in HbA1c.1

None of the patients with systemic hypersensitivity developed dulaglutide anti‑drug antibodies.1
