A Study to Assess the Long-term Safety of Octreotide Subcutaneous Depot in Patients With Acromegaly

Overview

About this study

The purpose of this trial is to assess the long-term safety of CAM2029 in patients with acromegaly. Patients will be administered CAM2029 subcutaneously once monthly during 12 months. Patients fulfilling trial NCT04076462 will be offered to continue with open-label treatment week 24-52 in this trial. Anticipate approximately 70 patients enrolled from start in this trial and approximately 70 patients to roll-over from trial NCT04076462.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
