RT, Temozolomide, and Bevacizumab Followed by Bevacizumab/Everolimus in First-line Treatment of GBM

2014-08-27 03:25:44 | BioPortfolio

Summary

In this phase II trial the investigators plan to incorporate two targeted agents, bevacizumab and everolimus, into the first-line multimodality therapy of glioblastoma. In the first portion of the treatment, bevacizumab will be added to standard concurrent radiation therapy plus temozolomide. After completing radiation therapy, patients will continue treatment with the combination of bevacizumab and everolimus.

Description

Although this maintenance regimen departs from the standard treatment with single agent temozolomide, we feel this approach may add to the overall efficacy of treatment for the following reasons: 1) results with bevacizumab/everolimus in renal cell carcinoma suggest there is at least an additive efficacy when these drugs are used in combination; 2) the efficacy of single agent temozolomide following standard concurrent radiation therapy/temozolomide has not been proven, 3) the use of the three-drug maintenance program (i.e., bevacizumab/everolimus/temozolomide) would probably not be tolerated well on a chronic basis in this patient population; and 4) the bevacizumab/everolimus combination has potential advantages as a maintenance therapy, since it has been well tolerated for many months in patients with other malignancies.

Medical and Biotech [MESH] Definitions

An anti-VEGF recombinant monoclonal antibody consisting of humanized murine antibody. It inhibits VEGF receptors and prevents the proliferation of blood vessels.

Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle. (From Escourolle et al., Manual of Basic Neuropathology, 2nd ed, p21)

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.

Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. military, purposes.
