Eligibility |
Inclusion criteria:
Subjects must meet all of the following inclusion criteria to be eligible for enrollment
into the study:
1. Adults (males and females) with a diagnosis of a clinically nonfunctioning pituitary
tumor of the silent corticotroph tumor type (i.e., positive adrenocorticotropin (ACTH)
staining on immunohistochemical staining of the pituitary tumor obtained at surgery)
2. Plasma POMC level > upper limit of normal
3. Prior pituitary tumor surgery with residual or recurrent pituitary tumor visible on
MRI scan that is = 5 mm from the optic chiasm.
4. Surgical resection of the pituitary adenoma must have occurred two or more months
prior to enrollment
5. If patients have undergone pituitary radiotherapy they must have completed their
course of radiotherapy at least 2 months prior to study screening
6. No prior somatostatin analog therapy
7. No concurrent use of dopamine agonist therapy
8. No active malignancy
9. Stable pituitary hormone supplements (x 2 months) prior to baseline visit
10. Sign and date an informed consent document indicating that the subject has been
informed of and agrees to all pertinent aspects of the trial
Exclusion criteria:
Subjects must not meet any of the following exclusion criteria to be eligible for
enrollment into the study:
1. Patients with Cushing's disease (biochemical evidence of hypercortisolism)
2. Patients with compression of the optic chiasm causing any visual field defect that
requires surgical intervention
3. Diabetic patients with poor glycemic control as evidenced by HbA1c >8%
4. Patients who are hypothyroid or adrenally insufficient and not on adequate replacement
therapy
5. Patients with symptomatic cholelithiasis and acute or chronic pancreatitis
6. Patients with risk factors for torsade de pointes, i.e., patients with a baseline QTcF
(Fridericia's Correction Formula value) >450 ms in males, and >460 ms in females
7. Hypokalaemia, hypomagnesaemia, uncontrolled hypothyroidism, family history of long QT
syndrome or concomitant medications with known risk of Torsades de pointes (TdP).
Drugs with possible risk of TdP should be avoided whenever feasible
8. Patients who have congestive heart failure (NYHA Class III or IV), unstable angina,
sustained ventricular tachycardia, clinically significant bradycardia, advanced heart
block, history of acute myocardial infarction (MI) less than one year prior to study
entry or clinically significant impairment in cardiovascular function
9. Concomitant disease(s) that could prolong the QT interval such as autonomic neuropathy
(caused by diabetes or Parkinson's disease), HIV, cirrhosis, uncontrolled
hypothyroidism or cardiac failure
10. Patients with liver disease such as cirrhosis, chronic active hepatitis, or chronic
persistent hepatitis, or patients with alanine aminotransferase (ALT)/aspartate
aminotransferase (AST) > 2.0 X upper limit of normal (ULN), serum bilirubin >2.0 X ULN
11. Presence of Hepatitis B surface antigen (HbsAg) or Hepatitis C antibody test
(anti-HCV)
12. Patients with serum creatinine >2.0 X ULN
13. Patients with white blood cell (WBC) count <3 X 109/L; Hb 90% < lower limit of normal
(LLN); platelet (PLT) count <100 X 109/L
14. Patients with the presence of active or suspected acute or chronic uncontrolled
infection
15. Patients who have undergone major surgery/surgical therapy for any cause within 4
weeks prior screening
16. Patients with abnormal coagulation (PT and/or activated partial thromboplastin time
(APTT) elevated by 30% above normal limits) or patients receiving anticoagulants that
affect PT (prothrombin time) or APTT (activated partial thromboplastin time)
17. History of syncope or family history of idiopathic sudden death
18. History of immunocompromise, including a positive HIV test result (ELISA and Western
blot)
19. Sexually active males unless they use a condom during intercourse while taking drug
and for 3 months following last dose of pasireotide and should not father a child in
this period. A condom is required to be used also by vasectomized men in order to
prevent delivery of the drug via seminal fluid
20. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a
female after conception and until the termination of gestation, confirmed by a
positive urine pregnancy test
21. Women of child-bearing potential, defined as all women physiologically capable of
becoming pregnant, unless they are using highly effective methods of contraception
during dosing and 3 months following last dose of pasireotide. Highly effective
contraception methods include:
- Total abstinence when this is in line with the preferred and usual lifestyle of
the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal,
post-ovulation methods) and withdrawal are not acceptable methods of
contraception
- Female sterilization (have had surgical bilateral oophorectomy with or without
hysterectomy) or tubal ligation at least six weeks before taking study treatment.
In case of oophorectomy alone, only when the reproductive status of the woman has
been confirmed by follow up hormone level assessment
- Male sterilization (at least 6 months prior to screening). For female subjects on
the study the vasectomized male partner should be the sole partner for that
subject
- Combination of any two of the following (a+b or a+c, or b+c):
1. Use of oral, injected or implanted hormonal methods of contraception or
other forms of hormonal contraception that have comparable efficacy (failure
rate <1%), for example hormone vaginal ring or transdermal hormone
contraception.
2. Placement of an intrauterine device (IUD) or intrauterine system (IUS)
3. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or
cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal
suppository
- In case of use of oral contraception women should have been stable on
the same pill for a minimum of 3 months before taking study treatment.
- Women are considered post-menopausal and not of child bearing potential
if they have had 12 months of natural (spontaneous) amenorrhea with an
appropriate clinical profile (e.g. age appropriate, history of
vasomotor symptoms) or have had surgical bilateral oophorectomy (with
or without hysterectomy) or tubal ligation at least six weeks ago. In
the case of oophorectomy alone, only when the reproductive status of
the woman has been confirmed by follow up hormone level assessment is
she considered not of child bearing potential.
