Phase II Study of SOM230 in Patients With Recurrent or Progressive Meningioma

PARTICIPANT SELECTION CRITERIA:

Inclusion Criteria:

1. Male or female patients aged 18 years or greater.
2. Patients with radiographically measurable disease and histologically confirmed recurrent or progressive intracranial meningiomas (refer to Appendix 1) who are not candidates for complete surgical resection of their tumors because the tumors are in eloquent areas of the brain (near critical neural structures)or are not candidates for cranial irradiation because a) they have already received radiation or b) the tumor is in close proximity to the optic nerve and radiation would likely result in vision damage.
3. Karnofsky Performance Status ≥ 60 (Requires occasional assistance, but is able to care for most of his/her personal needs.)
4. The following labs must not be clinically significant, as determined by PI. (Albumin, alkaline phosphatase, calcium, chloride, potassium, total protein, and sodium,)
5. Serum chemistries are as follows: bilirubin ≤ 1.5 X ULN, ALT or AST ≤ 2.5 X ULN, BUN ≤ 1.5X ULN, creatinine ≤ 1.5 X ULN.
6. Signed informed consent

Exclusion Criteria:

1. Patients receiving any cytotoxic chemotherapy, radiation or immunotherapy within 4 weeks prior to study enrollment
2. Patients who have undergone major surgery within 4 weeks(other than diagnostic surgery) or have not fully recovered, prior to study enrollment
3. Patients with malabsorption syndrome, short bowel syndrome, or chologenic diarrhea not controlled by specific therapeutic means
4. Patients with uncontrolled diabetes mellitus or a fasting plasma glucose > 1.5 ULN. Note: At the principle investigator's discretion, non-eligible patients can be re-screened after adequate medical therapy has been instituted.
5. Patients with symptomatic cholelithiasis
6. Patients who have congestive heart failure (NYHA Class III or IV), unstable angina, sustained ventricular tachycardia, ventricular fibrillation, clinically significant bradycardia, advanced heart block, or a history of acute myocardial infarction within the six months preceding enrollment.
7. Patients with congenital QTc syndrome, drug-induced prolonged QTc interval, or QTc measurement > 450 msec.
8. Patients with liver disease such as cirrhosis, chronic active hepatitis or chronic persistent hepatitis with serum bilirubin > 1.5 X ULN, and/ or ALT or AST > 2.5 X ULN
9. Patients with prior or concurrent malignancy except for the following: adequately treated basal cell or squamous cell skin cancer, or other adequately treated in situ cancer, or any other cancer from which the patient has been disease free for five years.
10. Patients with active or suspected acute or chronic uncontrolled infection or with a history of immunocompromise, including a positive HIV test result (ELISA and Western blot).
11. Patients with ANC <1.5 X 109/L; Hgb <10 g/dL; PLT <100 X 109/L
12. Patients who have any current or prior medical condition that, in the opinion of the Investigator, may interfere with the conduct of the study, the evaluation of its results, or the rigorous completion of the informed consent process.
13. Female patients who are pregnant or lactating, or adults of childbearing potential who are not practicing a medically acceptable method of birth control. Female patients must use barrier contraception in addition to condom use in their partner. If oral contraception is used, the patient must have been practicing this method for at least two months prior to enrollment and must agree to continue the oral contraceptive throughout the course of the study, and for three months after the study has ended. Male patients who are sexually active are required to use condoms during the study and for three months afterward.
14. Patients who have participated in any clinical investigation with an investigational drug (other than SOM230) within 1 month prior to study drug dosing.
15. Known hypersensitivity to somatostatin analogues or any component of the pasireotide or octreotide LAR or s.c. formulations (see section 6.1.1)
16. Patients with a history of non-adherence to medical regimens or who are considered potentially unreliable or will be unable to complete the entire study
17. QTcF at screening > 450 msec.
18. History of syncope or family history of idiopathic sudden death.
19. Sustained or clinically significant cardiac arrhythmias.
20. Risk factors for Torsades de Pointes such as hypokalemia, hypomagnesemia, cardiac failure, clinically significant/symptomatic bradycardia, or high-grade AV block.
21. Concomitant disease (s) that could prolong QT such as autonomic neuropathy (caused by diabetes, or Parkinson's disease), HIV, cirrhosis, uncontrolled hypothyroidism or cardiac failure.
22. Concomitant medication (s) known to increase the QT interval.
