High-Dose and High-Frequency Lanreotide Autogel in Acromegaly: A Randomized, Multicenter Study

Context: Increase in drug frequency or dose is recommended for acromegaly patients with partial response to long-acting somatostatin receptor ligands (SRLs). However, the efficacy and safety data with lanreotide (LAN) Autogel (LAN-ATG) at high dose (HD) or high frequency (HF) are still scanty. Objective: To evaluate the biochemical efficacy and safety of HF and HD LAN-ATG in patients with active acromegaly. Design: Twenty-four-week prospective, multicenter, randomized, open-label trial. Patients and Interventions: Thirty patients with active acromegaly, partial responders to SRLs, were randomized to HF (120 mg/21 days; 15 patients) or HD (180 mg/28 days; 15 patients) LAN-ATG. Outcomes: Normalization of serum insulin-like growth factor-I (IGF-I) and reduction in random growth hormone (GH) values ,1.0 mg/L, reduction in serum IGF-I and GH from baseline, differences in biochemical response between HF and HD LAN-ATG, adverse events. Results: IGF-I decreased significantly (P = 0.007) during...
