Calcitonin Gene-Related Peptide (CGRP)

Intravenous, Subcutaneous injection

Overview

Calcitonin gene-related peptide is a 37-amino acid neuropeptide produced by alternative splicing of the calcitonin gene. CGRP acts as a potent vasodilator and plays a key role in migraine pathophysiology by binding to CGRP receptors on vascular smooth muscle and trigeminal nerve endings.

Mechanism of Action

While CGRP itself has effects on bone metabolism through regulation of osteoblast and osteoclast activity, therapeutic development has focused primarily on antagonizing CGRP signaling rather than administering the peptide. The peptide's role in bone includes modulation of bone formation and vascular coupling in skeletal tissue..

Research Summary & Key Findings

CGRP antagonists (gepants) and monoclonal antibodies targeting CGRP or its receptor have demonstrated efficacy in migraine prevention and treatment across multiple phase 3 trials. Research on CGRP's direct bone effects comes primarily from rodent models showing that CGRP-deficient mice exhibit altered bone density and that local CGRP administration can influence fracture healing. Clinical evidence for exogenous CGRP use in bone disorders remains limited, with most translational interest centered on understanding potential skeletal effects of CGRP-blocking therapies.

Clinical Status

Research Phase

Calcitonin Gene-Related Peptide (CGRP) is in the research phase with limited clinical data in humans. Current evidence is primarily derived from preclinical (animal or in vitro) studies.
