Brief Summary
This is a single-arm, phase II trial of SOM230 in patients with documented recurrent or progressive intracranial meningioma who have failed conventional therapy and are not candidates for complete surgical resection of their tumors and/or radiation at the time of study entry. At the time of the final analysis, all patients who are receiving treatment with SOM230 will complete the core phase of the study and will continue on the extension phase. During this time, additional data on response duration, PFS, and safety will be collected.
Detailed Description
Study rationale/purpose: Most, though not all (Lamberts 1995; Koper 1992) in vitro studies suggest that the addition of somatostatin inhibits meningioma growth, and accelerates apoptosis, suggesting a potential therapeutic role for somatostatin receptor agonists (Arena 2004). SOM230 (pasireotide) is a novel somatostatin analogue with affinity for multiple somatostatin receptors. Compared to octreotide (Sandostatin®), SOM230 binds to a wider spectrum of somatostatin receptors, including subtypes 1, 2, 3, and 5, and possesses as a higher binding affinity for subtypes 1, 3, and 5). In a recent study evaluating the expression of somatostatin receptor mRNA in human meningiomas (Arena 2004), 88% of the tumors (37/42) were positive for at least 1 of the 5 SSTR subtypes. SSTR1 and SSTR2 were most commonly detected in meningiomas (69 % (29/42) and 79% (33/42) respectively). The other subtypes were also frequently detected (43%, 33%, and 33% for SSTR3, SSTR4, and SSTR5 respectively). In recently completed studies with SOM230 in patients with Cushing's disease and acromegaly, clinical responses have been documented in patients who were refractory to Sandostatin. In summary, SOM230 has broader binding affinity to somatostatin receptors than Sandostatin®, its toxicity is very modest, and qualitatively identical to that of Sandostatin®, and its longer half-life (approximately 23 hours) allows a more convenient (twice daily in contrast to three times a day) dosing schedule compared with Sandostatin®. For all these reasons, we anticipate that the efficacy and tolerability of SOM230 in patients with recurrent meningiomas should be better than that observed with Sandostatin. We therefore, propose a formal phase II trial of SOM230 (pasireotide) in patients with recurrent or progressive meningiomas who have already undergone or are not candidates for additional surgery or radiation. OBJECTIVES: Primary objective To determine the objective response rate (ORR) (complete response [CR] plus partial response [PR]) of SOM230 monotherapy in patients with recurrent or progressive meningiomas who have previously undergone or are not candidates for additional surgery or radiation. Secondary objectives To determine the duration of response to SOM230 To establish the 6-month progression-free survival rate To establish the median PFS and overall survival (OS) To determine the clinical benefit rate (CR + PR + stable disease) of SOM230 To characterize the safety and tolerability of SOM230 Exploratory objectives To determine the pharmacokinetic profile of SOM230 To analyze the expression of somatostatin receptor subtypes in tumor specimens (by immunohistochemistry) and in study participants (by octreotide scan). Please refer to sections 7.7.2 and 7.5.4.5 of the full protocol. To measure serum IGF levels in patients prior to and after receiving SOM230 To determine the ORR for Grade 1 versus Grade 2 /3 meningiomas SOM230 will be administered to all patients at a dose of 1200 µg given subcutaneously twice daily (Figure). One treatment cycle will be defined as four weeks of therapy. Complete blood counts will be obtained, and neurologic examinations and contrast-enhanced cranial MRI scans will be performed as described below (see Table 7-1). Serum IGF levels will be measured at the start of treatment, and at each MRI assessment point. Plasma pharmacokinetic studies will be performed in the subset of patients who consent to this additional study procedure. Participation in the pharmacokinetic component of this study is not mandatory. All patients will continue to receive SOM230 until disease progression or death occurs, unacceptable toxicity is reported, or the patient declines further therapy. In patients with stable (clinically unchanged or improved and radiographic disease increase or decrease in tumor size by less than 25%) or responding disease (clinically unchanged or improved and radiographic disease decrease in size by 50% or more), three additional cycles of SOM230 will be adminis¬tered, following which patients will be reassessed. Post-Treatment Evaluation, Study Completion, and Survival Phase Study evaluation and determination of response status will be performed every 3 treatment cycles for the first 12 cycles of therapy and every 6 cycles thereafter for the duration of SOM230 treatment. At the time of the final primary analysis, all patients who are continuing to receive treatment with SOM230, as well as those who are being followed for post-treatment evaluations, and those who are being followed for survival only will complete the core phase of the study and will transition to the extension phase. During the extension phase, data on response duration, PFS and safety will continue to be collected. Study completion will be declared following documentation of objective tumor progression by Macdonald and Levin criteria (either while on-treatment or during post-treatment evaluations) or at the time of death. It is critical that objective tumor progression by Macdonald and Levin criteria be documented for each patient. In the event of treatment discontinuation prior to objective disease progression, patients will remain eligible for ongoing post-treatment evaluations. All antineoplastic therapies administered during the post-treatment phase will also be recorded as part of the post-treatment evaluation phase.

Intervention Description
SOM230 is an injectable somatostatin analogue. Like natural somatostatin and other somatostatin analogues (SRIFa), SOM230 exerts its pharmacological activity via binding to somatostatin receptors (sst). There are five known somatostatin receptors: sst 1, 2, 3, 4 and 5. Somatostatin receptors are expressed in different tissues under normal physiological conditions. Somatostatin analogues activate these receptors with different potencies (Schmid and Schoeffter 2004) and this activation results in a reduced cellular activity and inhibition of hormone secretion. Somatostatin receptors are strongly expressed in many solid tumors, especially in neuroendocrine tumors where hormones are excessively secreted e.g. acromegaly (Freda 2002), GEP/NET tumors (Oberg, et al 2004) and Cushing's disease.
