ABSTRACT
Introduction: Acromegaly is a chronic disease with high morbidity and enhanced mortality if left untreated. Treatment options include surgery, medical therapy (somatostatin analogues (SA), dopamine agonists (DA) and growth hormone receptor antagonists) and radiotherapy. Despite these treatment options, “real-life” studies have shown that approximately 50% of patients are not controlled. In this scenario, a next-generation SA, pasireotide, has recently been approved for the treatment of acromegaly.
Areas covered: 1) pasireotide’s pharmacokinetics and pharmacodynamics; 2) pasireotide’s anti-secretory and anti-proliferative effects, from preclinical studies up to phase III clinical trials; and 3) the adverse effects of pasireotide, focusing on hyperglycemia; 4) biomarkers of response to SA treatment.
Expert opinion: surgery is the primary treatment for most patients with acromegaly; however, approximately half of them will need adjuvant therapy. At present, the decision of this adjuvant treatment is made on a “trial-and-error” fashion. Nevertheless, in recent years, efforts have been made to establish biomarkers for the response to drugs involved in the treatment of acromegaly, which will change the treatment of acromegaly towards a more personalized therapeutic decision-making process. In the near future, the establishment of pasireotide response biomarkers will allow us to identify good candidates for first-line medical monotherapy with pasireotide.
