Pasireotide LAR and Pegvisomant Study in Acromegaly
Pasireotide LAR and Pegvisomant Study in Acromegaly
The objective of this study is to assess the efficacy of Pasireotide Long Acting Release
 (LAR) alone and in combination with weekly Pegvisomant (PEGV) in acromegaIy patients
 previously controlled with combination treatment of long-acting Somatostatin analogs
 (LA-SSAs) and PEGV.
Pasireotide Long Acting Release (Signifor ®), a novel long-acting multi-receptor ligand
 somatostatin analogue, has been shown to be more effective for the treatment of GH-secreting
 pituitary adenomas than currently used long-acting somatostatin analogues (LA-SSAs). The
 long-term efficacy of acromegaly patients using LA-SSAs in combination with PEGV was over 90%
 in terms of normalization of IGF-I. The combination of PEGV with pasireotide LAR has not been
 studied yet. Combining PEGV with pasireotide LAR could result in a lower dose and less
 injections of pegvisomant. This may ultimately lead to a more cost-effective treatment and
 improved quality of life.
Inclusion Criteria:

 -  written informed consent male or female aged ≥ 18 years

 -  documentation supporting the diagnosis of acromegaly based on elevated GH and/or IGF-I
 levels due to a pituitary tumor

 -  the patient is treated with lanreotide Autogel or octreotide LAR and PEGV (twice)
 weekly for at least 6 months and has a serum IGF-I level within 120 % of the age
 adjusted normal limits. These patients were previously not controlled by somatostatin
 analogs alone.

 -  female of no childbearing potential or male. No childbearing potential is defined as
 being postmenopausal for at least 1 year, or women with documented infertility
 (natural or acquired) or using two acceptable contraceptive measures, except for oral
 contraceptives.

 -  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. use a condom)
 for the duration of the study

 -  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.

 Exclusion Criteria:

 Patients will not be included in the study if he or she:

 -  has undergone pituitary surgery or radiotherapy within 6 months prior to study entry.

 -  it is anticipated that the patient will receive pituitary surgery or radiotherapy
 during the study.

 -  has a history of hypersensitivity to lanreotide, octreotide or pegvisomant or drugs
 with a similar chemical structure

 -  has been treated with any unlicensed drug within the last 30 days before study entry.

 -  has abnormal hepatic function at study entry (defined as AST, ALT, gGT, alkaline
 phosphatase, or total bilirubin above 3 ULN)

 -  is at risk of pregnancy or is lactating. Females of childbearing potential must
 provide a negative pregnancy test within 5 days before the start of the study and must
 be using contraception. Non-childbearing potential is defined as post-menopause for at
 least one year, surgical sterilization or hysterectomy at least three months before
 the start of the study.

 -  has a history of, or known current problems with alcohol or drug abuse.

 -  has a mental condition rendering the subject unable to understand the nature, scope
 and possible consequences of the study, and/or evidence of an uncooperative attitude.

 -  has abnormal baseline findings, any other medical condition(s) or laboratory findings
 that, in the opinion of the investigator, might jeopardize the subject's safety or
 decrease the chance of obtaining satisfactory data needed to achieve the objective(s)
 of the study.

 -  renal insufficiency, clearance < 50ml/min

 -  poorly controlled diabetes mellitus with an HbA1c > 9.0%

 -  patients with a QTc > 500 ms on the EKG

 -  participation in a clinical trial in the last 6 months
