A Phase II, Multi-site, Open-label, Dose-titration Trial to Investigate the Safety, Tolerability, Pharmacokinetics, and Efficacy of Lu AG13909 in Adults With Cushing's Disease
This trial will evaluate the effects of Lu AG13909 in adult participants with Cushing's disease (CD). CD is a rare and serious disorder where the body makes too much of a hormone called cortisol. The main goals of this trial are to learn about 1. the effect of Lu AG13909 on cortisol levels. 2. the safety and tolerability of Lu AG13909. 3. the pharmacokinetic parameters of Lu AG13909 (how the drug is absorbed, distributed, and processed by the body).
• The participant is a man or woman with a confirmed diagnosis of adrenocorticotropic hormone (ACTH) driven CD of pituitary source as per current guidelines
• Morning plasma ACTH levels \> lower limit of normal (LLN) and
• Evidence of a pituitary origin of the excess ACTH:
• i. Either MRI confirmation of pituitary adenoma \>6 millimeters (mm), or ii. inferior petrosal sinus gradient \>2, or iii. histopathology confirmation of ACTH-secreting tumour
• The participant has a 24-hour UFC \>1.5 × ULN (the mean of ≥3 days of 24-hour urine collection).
• Apart from CD and associated well-controlled comorbidities (for example, diabetes mellitus and hypertension), the participant is generally healthy in the opinion of the investigator and based on medical history, physical examination, vital signs, electrocardiogram (ECG), and the results of the safety laboratory tests.
• For participants on medical treatment for hypercortisolism due to CD, pre-defined washout periods must be completed prior to the Baseline efficacy assessments.
