Vismodegib and FAK Inhibitor GSK2256098 in Treating Patients With Progressive Meningiomas


This clinical trial will study how well drugs called Vismodegib and GSK2256098 work in treating patients with meningioma that is growing, spreading, or getting worse. These drugs are examples of targeted drug therapy, and may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Vismodegib is a small-molecule drug that has been approved for use in basal cell carcinoma, and is currently being evaluated for use in treating brain tumors. Vismodegib suppresses the activity of a signaling pathway called Hedgehog. The Hedgehog signaling pathway is involved in cell growth, and is abnormally active in some cancers, including some meningiomas.

GSK2256098 is a drug that inhibits FAK, a protein that is abnormally active in various tumor cell types. Excess FAK signaling promotes tumor progression and metastasis by regulating tumor cell migration, proliferation, and survival. By inhibiting FAK, this drug may be effective in stopping the growth of tumors.

This Phase II clinical trial will evaluate the efficacy of these drugs in the following two groups:

  • Patients with SMO/PTCH1 mutation: Vismodegib
  • Patients with NF2 mutation: GSK2256098


  1. Documentation of disease:
  2. Histologic documentation: histologically proven intracranial meningioma as documented by central pathology review
  3. Molecular documentation: presence of SMO, PTCH1 or NF2 mutation in tumor sample as documented by central laboratory
  4. Progressive OR residual disease, as defined by the following:
    1. Residual measurable disease: residual measurable disease immediately after surgery without requirement for progression; for grade I disease, progression pre-operatively needs to be documented, with an increase in size of the measurable primary lesion on imaging by 25% or more (bidirectional area); the change must occur between scans separated by no more than 12 months; residual measurable disease will be defined by bidimensionally measurable lesions with clearly defined margins by MRI scans, with a minimum diameter of 10 mm in both dimensions
    2. Progressive measurable disease: progression defined as an increase in size of the measurable primary lesion on imaging by 25% or more (bidirectional area); the change must occur between scans separated by no more than 12 months
    3. Post radiation patients: patients with measurable and progressive meningioma who have received radiation are potentially eligible, but need to show evidence of progressive disease after completion of radiation; at least 24 weeks must have elapsed from completion of radiation to registration
  5. Measurable disease: measurable disease is defined by a bidimensionally measurable main lesion on MRI or computed tomography (CT) images (MRI preferred) with clearly defined margins; multifocal disease is allowed
  6. Prior treatment
    1. Prior medical therapy is allowed but not required
    2. No limit on number of prior therapies  
    3. No chemotherapy, other investigational agents within 28 days of study treatment
    4. No other concurrent investigational agents or other meningioma-directed therapy (chemotherapy, radiation) while on study
    5. For patients treated with external beam radiation, interstitial brachytherapy or radiosurgery, an interval > 24 weeks must have elapsed from completion of radiation therapy to registration
    6. Steroid dosing stable for at least 4 days
    7. Recovered to Common Terminology Criteria for Adverse Events (CTCAE) grade 1 or less toxicity from other agents with exception of alopecia and fatigue
    8. No craniotomy within 28 days of registration
  7. Not pregnant and not nursing:
    1. A female of childbearing potential is a sexually mature female who:
      1. has not undergone a hysterectomy or bilateral oophorectomy; or
      2. has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)
  8. Eastern Cooperative Oncology Group (ECOG) performance status =< 2
  9. Patient history:
    1. Patients with history of neurofibromatosis (NF) may have other stable central nervous system (CNS) tumors (schwannoma, acoustic neuroma or ependymoma) if lesions have been stable for 6 months
    2. No metastatic meningiomas (as defined by extracranial meningiomas) allowed
    3. No history of allergic reactions attributed to compounds of similar or biologic composition to assigned study drug 
    4. No known active hepatitis B or C
    5. No current Child Pugh class B or C liver disease
    6. No uncontrolled gastric ulcer disease (grade 3 gastric ulcer disease within 28 days of registration)
    7. No uncontrolled diabetes defined as a known diabetic with hemoglobin A1C (HBA1C) > 7.5 OR fasting glucose > 140
    8. No uncontrolled hypertension defined as blood pressure (BP) > 140/90
    9. No abdominal fistula, gastrointestinal (GI) perforation, or intra-abdominal abscess within 28 days prior to registration 
  10. Concomitant medications:
    1. Chronic concomitant treatment with strong inhibitors of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inhibitors must discontinue the drug for 14 days prior to registration on the study for patients with NF2 mutation enrolled to GSK2256098
    2. Chronic concomitant treatment with strong CYP3A4 inducers is not allowed; patients must discontinue the drug 14 days prior to the start of study treatment for patients with NF2 mutation enrolled to GSK2256098
  11. Absolute neutrophil count (ANC) >= 1,500/mm^3
  12. Platelet count >= 100,000/mm^3
  13. Creatinine OR =< 1.5 mg/dl x upper limit of normal (ULN) OR calculated (calc.) creatinine clearance > 45 mL/min
  14. Urine protein:creatinine ratio (UPC) =< 45 mg/mmol; ONLY APPLICABLE for patients with NF2 mutation (GSK2256098)
  15. Total bilirubin =< 1.5 x upper limit of normal (ULN); except in case of Gilbert's disease
  16. Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 2.5 x upper limit of normal (ULN)
  17. Fasting triglyceride =< 200 mg/dL; ONLY APPLICABLE for patients with NF2 mutation (GSK2256098)
  18. Fasting cholesterol =< 240 mg/dL; ONLY APPLICABLE for patients with NF2 mutation (GSK2256098)
  19. Corrected QC interval calculated using Fridericia's formula (QTcF) =< 500 msec; ONLY APPLICABLE for patients with NF2 mutation (GSK2256098)
