E.3 | Principal inclusion criteria |
(1) Provided written informed consent prior to any study related procedures. (2) Subjects will have a documented diagnosis of acromegaly. (3) Subjects will have active acromegaly confirmed by a mean serum concentration of GH over 2 hours > 2.5 µg/L at screening analysed by central laboratory. (4) Subjects who have had pituitary surgery must be >8 weeks post-surgery. (5) 18 to 75 years of age. (6) Negative pregnancy test (female subjects). (7) Female who is either of non-childbearing potential or who is not pregnant at screening and agrees to use highly effective contraception during whole duration of the study. Non-childbearing potential is defined as being postmenopausal for at least 1 year, or women with documented infertility (natural or acquired). (8) Male subjects must agree that, if their partner is at risk of becoming pregnant, they will use a medically accepted, effective method of contraception (i.e. condom) for the duration of the treatment period of the study. (9) Subjects must be willing and able to comply with study restrictions and to remain at the clinic for the required duration during the study period and willing to return to the clinic for the follow up evaluation as specified in the protocol. |
|
E.4 | Principal exclusion criteria |
(1) The subject has received long-acting SSA within 12 weeks prior screening (e.g. octreotide long acting release (LAR), lanreotide Autogel, pasireotide LAR). (2) The subject has received short-acting SSA within 1 week (e.g. octreotide s.c.) prior to screening. (3) The subject has received a dopamine agonist within 6 weeks (e.g. bromocriptine or cabergoline) prior to screening. (4) The subject has received GH antagonist within 12 weeks prior to screening (e.g. pegvisomant). (5) The subject had undergone radiotherapy to the pituitary gland at any time prior to study entry. (6) It is anticipated that the subject will undergo pituitary surgery or radiation to the pituitary gland during the study, or will require additional medical therapy for acromegaly (including SSA, pegvisomant, or dopamine agonists) during the study. (7) The subject has unsubstituted/untreated adrenal insufficiency. (8) If the subject has any history of postural hypotension or evidence of postural hypotension at screening (>= 20 mm Hg decrease in SBP, >= 10 mm Hg decrease in DBP, or >=30 bpm increases in pulse rate, after standing for 2 minutes from resting supine position of at least 10 min).

(11) Subject is taking beta-blockers (which can inhibit compensatory increases in HR during hypotensive episodes). (12) Subject is taking Clonidine, Alpha-blockers, Verapamil and Diltiazem, Amiodarone, Ivabradine and Anti-cholinesterase drugs. (13) Subject is being treated for hypertension and in the opinion of the Investigator their antihypertensive medication puts them at increased risk of postural hypotension. (14) Subject is hypotensive at screening as defined as systolic < 90 mmHg and/or diastolic <60 mmHg. (15) Subject has clinically significant hepatic abnormalities and/or ALT and/or AST ≥2 x ULN and/or alkaline phosphatase (ALP) ≥2 x ULN and/or total bilirubin ≥1.5 x ULN and gamma-glutamyl transferase (GGT) ≥2.5 x ULN during the screening period (local laboratory results). (16) Subject has a compression of the optic chiasm causing visual-field defects. (17) Subject with a life expectancy of < 1 year. (18) Subject is receiving any oestrogen-containing Hormone Replacement Therapy (HRT). (19) Subject is receiving neuroleptic antipsychotic/antiemetic drugs. (20) Subject has clinically significant pancreatic abnormalities and/or amylase and/or lipase ≥2 x ULN during the Screening period (local laboratory results). (21) Any significant renal abnormalities, including confirmed proteinuria and/or creatinine ≥1.5x ULN during screening assessed by the local laboratory. (22) Subject has any known uncontrolled cardiovascular disease or any of the following within 6 months of Screening: ventricular or atrial dysrhythmia ≥ common terminology criteria for adverse event (CTCAE) grade 2, bradycardia ≥ CTCAE grade 2, electrocardiogram (ECG), QTc prolonged ≥ CTCAE grade 2, myocardial infarction, severe/unstable angina, symptomatic congestive heart failure, cerebrovascular accident or transient ischemic attack, pulmonary embolism, hypertension not adequately controlled by current medications. (23) Subject with history of, or known current, problems with alcohol or drug abuse. (24) Subject with any mental condition rendering him/her unable to understand the nature, scope and possible consequences of the study, and/or evidence of an uncooperative attitude. (25) Subject with uncontrolled hypothyroidism. (26) Subject with abnormal coagulation. (27) Subject with previously known immune compromise. (28) Subject with history of gallstones or any gallstones/sludge observed at screening gallbladder echography (local assessment). (29) Subject has been treated with any other IMP prior to the first study visit without undergoing a washout period of seven times the elimination t1/2 of the investigational compound. (30) Subject has a known hypersensitivity to any of the test materials or related compounds. (31) Subject had abnormal findings during the screening period, any other medical condition(s) or laboratory findings that, in the opinion of the Investigator, might jeopardise the subject's safety or ability to complete the study. (32) Blood donation within the last 3 months. |
