Investigational drugs for the Treatment of Acromegaly: new agents to transform therapy.

Disease control is essential to decrease morbidity burden and mortality in acromegaly patients. In the last decades, the availability of new drugs increased the rate of disease control. However, up to 55% of patients remain uncontrolled despite available treatment strategies in real-world data. The reasons for this finding may include poor adherence, inadequate tolerability, therapeutic inertia, and high costs. Since acromegaly is a chronic disease and medical therapy is usually life-long, patient's adherence to treatment is fundamental in both achieving and maintaining disease control. Less invasive routes of administration could improve adherence and concur to increase disease control rate. The aim of current review is to provide a detailed update about investigational drugs for acromegaly treatment currently under investigation as paltusotine, ONO-5788, AP102, GT-02037, ISIS 766,720, CAM2024, Lanreotide PRF, DP1038, MTD201, solid dose injection of octreotide. Medical therapy of acromegaly is an evolving field. Current studies are addressing patient's needing for both new molecules and less invasive routes of administration for already existing drugs. It cannot be ruled out that drugs currently used for other disease such as cancers could be considered in the future for the treatment of acromegaly.
