Lanreotide

approved

Also known as: Somatuline, BIM 23014

**Mechanism of Action** Lanreotide is a synthetic somatostatin analog with high affinity for somatostatin receptor subtypes 2 (SSTR2) and 5 (SSTR5). By binding to these receptors, it inhibits the secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1), as well as various neuroendocrine hormones (e.g., serotonin, gastrin, glucagon). Its depot formulation provides sustained release, enabling prolonged suppression of hormonal activity in conditions such as acromegaly and gastroenteropancreatic neuroendocrine tumors (GEP-NETs). **Key Research Findings** Clinical trials (e.g., the ELECT and CLARINET studies) demonstrated that lanreotide effectively normalizes GH and IGF-1 levels in acromegaly patients and significantly prolongs progression-free survival in patients with well-differentiated, non-functioning GEP-NETs. Pharmacokinetic data confirm stable drug concentrations over 28 days with monthly intramuscular injections. Adverse effects are typically mild and include gastrointestinal disturbances, gallstones, and transient injection-site reactions. **Clinical Relevance** Lanreotide is a first-line therapy for acromegaly and a standard treatment for unresectable or metastatic GEP-NETs. Its long-acting formulation improves patient compliance compared to daily injections. Ongoing research explores its utility in other neuroendocrine tumors and polycystic liver disease.
