Radiation Therapy and Temozolomide Followed by Temozolomide Plus Sorafenib for Glioblastoma Multiforme

21 de julio de 2016 actualizado por: SCRI Development Innovations, LLC

A Phase II Trial of Concurrent Radiation Therapy and Temozolomide Followed by Temozolomide Plus Sorafenib in the First-Line Treatment of Patients With Glioblastoma Multiforme

The mechanism of action of sorafenib makes it an interesting drug to investigate in the treatment of patients with glioblastoma multiforme. Efficacy of agents with anti-angiogenic activity has already been demonstrated and the PDGF receptor target may also be pertinent in glioblastoma. The combination of temozolomide plus sorafenib has been investigated previously in the treatment of patients with advanced melanoma. The combination was generally well tolerated; in previously untreated patients, a standard dose of sorafenib (400mg PO bid) was administered with temozolomide 150mg/m2 PO daily for 5 days, repeated every 28 days (23).

In this multicenter phase II study, patients with newly diagnosed glioblastoma will receive standard treatment, including initial debulking surgical resection (if feasible) followed by high-dose radiation therapy with concurrent temozolomide. After completion of radiation therapy, patients will continue treatment with temozolomide (150mg/m2 days 1-5) and sorafenib (400mg PO bid daily), repeated at 28-day intervals for 6 cycles.

Descripción detallada

All patients entering this study will initially undergo combined modality treatment with concurrent radiation therapy + temozolomide. Four weeks after completing radiation therapy, patients will begin 6 months of follow-up treatment with oral temozolomide plus sorafenib.

Combined Modality Therapy - Radiation Therapy Radiotherapy must begin within ≤ 6 weeks of surgery. One treatment of 2.0Gy will be given daily 5 days per week for a total of 60.0Gy over 6 weeks. Temozolomide 75mg/m2 PO will be given daily, beginning on the first day of radiation therapy and continuing through the last day of radiation therapy.

After completion of combined modality therapy, patients will have 4 weeks without any therapy.

Systemic Therapy Beginning 4 weeks after the completion of radiation therapy, patients will receive 6 months of treatment with temozolomide and sorafenib. Temozolomide 150mg/m2 orally will be administered days 1-5, and repeated every 28 days for 6 courses. Sorafenib 400mg PO bid will be administered on days 1-28, repeated for 6 courses concurrently with temozolomide

Descripción

Inclusion Criteria:

  1. Histologically confirmed intracranial glioblastoma multiforme (WHO grade 4).
  2. Patients who have had partial or complete surgical debulking are eligible, as are those with inoperable glioblastoma.
  3. No previous treatment for glioblastoma except for previous surgical debulking (i.e. no previous radiotherapy, local chemotherapy, or systemic therapy).
  4. ECOG performance status 0 or 1 (See Appendix C)
  5. Age ≥ 18 years
  6. Adequate bone marrow function: hemoglobin ≥ 9.0g/dL; ANC ≥ 1500/μL; platelet count ≥ 100,000/μL.

  7. Adequate liver function

    • Total bilirubin ≤ 1.5 x ULN
    • ALT and AST ≤ 2.5 x ULN
  8. Serum creatinine < 1.5 x ULN
  9. Women of child-bearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment. Women must agree to not breast feed while receiving study treatment.

However, patients receiving anticoagulation treatment with an agent such as warfarin or heparin are also eligible. For patients on warfarin, the INR should be measured prior to initiation of sorafenib and monitored at least weekly, or as defined by the local standard of care, until INR is stable.

Objective Response
Periodo de tiempo: every 8 weeks until disease progression, estimated 18 months

The number of patients with complete or partial responses measured from the time of initial response to documented tumor progression. Radiologic response was defined using the Macdonald criteria.

The Macdonald criteria divides response into 4 types of response based on imaging (MRI) and clinical features, as follows: 1) complete response (CR); 2) partial response (PR); 3) stable disease (SD); and 4) progression (PD).

Criteria:

CR: disappearance of all enhancing disease (measurable and non-measurable) sustained for at least 4 weeks, no new lesions. No corticosteroids, clinically stable or improved.

PR: >=50% decrease of all measurable enhancing lesions, sustained for at least 4 weeks, no new lesions. Stable or reduced corticosteroids, clinically stable or improved.

SD: does not qualify for complete response, partial response or progression. Clinically stable.

PD: >= 25% increase in enhancing lesions, any new lesions. Clinical deterioration.
