A combinatory vaccine with IMA950 plus varlilumab promotes effector memory T-cell differentiation in the peripheral blood of patients with low-grade gliomas.

Background: Central nervous system (CNS) WHO grade 2 low-grade glioma (LGG) patients are at high risk for recurrence and with unfavorable long-term prognosis due to the treatment resistance and malignant transformation to high-grade glioma. Considering the relatively intact systemic immunity and slow-growing nature, immunotherapy may offer an effective treatment option for LGG patients.

Methods: We conducted a prospective, randomized pilot study to evaluate the safety and immunological response of the multipeptide IMA950 vaccine with agonistic anti-CD27 antibody, varlilumab, in CNS WHO grade 2 LGG patients.

Randomized trial of neoadjuvant vaccination with tumor-cell lysate induces T cell response in low-grade gliomas.

BACKGROUNDLong-term prognosis of WHO grade II low-grade gliomas (LGGs) is poor, with a high risk of recurrence and malignant transformation into high-grade gliomas. Given the relatively intact immune system of patients with LGGs and the slow tumor growth rate, vaccines are an attractive treatment strategy.METHODSWe conducted a pilot study to evaluate the safety and immunological effects of vaccination with GBM6-AD, lysate of an allogeneic glioblastoma stem cell line, with poly-ICLC in patients with LGGs.

Attitudes toward fertility and fertility preservation in women with glioma.

Background: No studies have examined the fertility priorities of women undergoing treatment for their glioma. Glioma patients frequently undergo chemotherapy as part of their treatment; however, it is unknown whether patients truly are aware of its possible effects on their fertility. Our objective was to assess the fertility priorities of glioma patients and ascertain whether female glioma patients are being effectively counseled on the effects of chemotherapy on their fertility prior to beginning treatment.

A phase 1 trial of intravenous liposomal irinotecan in patients with recurrent high-grade glioma.

Purpose: Preclinical activity of irinotecan has been seen in glioma models, but only modest efficacy has been noted in clinical studies, perhaps related to drug distribution and/or pharmacokinetic limitations. In preclinical testing, irinotecan liposome injection (nal-IRI) results in prolongation of drug exposure and higher tissue levels of drug due to slower metabolism and the effect of enhanced permeability and retention. The objective of the current study was to assess the safety and pharmacokinetics (PK) of nal-IRI and to determine the maximum tolerated dose (MTD) in patients with recurrent high-grade glioma stratified based on UGT1A1 genotyping.

A single-institution phase II trial of radiation, temozolomide, erlotinib, and bevacizumab for initial treatment of glioblastoma.

Background: Both the epidermal growth factor receptor and vascular endothelial growth factor pathways are frequently overexpressed in glioblastoma multiforme. This study combined bevacizumab, a vascular endothelial growth factor inhibitor, and erlotinib, an epidermal growth factor receptor inhibitor, with standard radiation and temozolomide (TMZ), with the goal of improving overall survival (OS).

Methods: Treatment consisted of fractionated radiotherapy to 60 Gy, with daily TMZ at 75 mg/m²/d and erlotinib 150-200 mg/d (or 500-600 mg/d for patients on enzyme-inducing antiepileptic drugs).

Identifying the needs of brain tumor patients and their caregivers.

The purpose of this study is to identify the needs of brain tumor patients and their caregivers to provide improved health services to these populations. Two different questionnaires were designed for patients and caregivers. Both questionnaires contained questions pertaining to three realms: disease symptoms/treatment, health care provider, daily living/finances.

Phase II study of erlotinib plus temozolomide during and after radiation therapy in patients with newly diagnosed glioblastoma multiforme or gliosarcoma.

Purpose: This open-label, prospective, single-arm, phase II study combined erlotinib with radiation therapy (XRT) and temozolomide to treat glioblastoma multiforme (GBM) and gliosarcoma. The objectives were to determine efficacy of this treatment as measured by survival and to explore the relationship between molecular markers and treatment response.

Patients And Methods: Sixty-five eligible adults with newly diagnosed GBM or gliosarcoma were enrolled.

Quality of life in low-grade glioma patients receiving temozolomide.

The purpose of this study was to describe the quality of life (QOL) of low-grade glioma (LGG) patients at baseline prior to chemotherapy and through 12 cycles of temozolomide (TMZ) chemotherapy. Patients with histologically confirmed LGG with only prior surgery were given TMZ for 12 cycles. QOL assessments by the Functional Assessment of Cancer Therapy-Brain (FACT-Br) were obtained at baseline prior to chemotherapy and at 2-month intervals while receiving TMZ.

Phase 1 study of erlotinib HCl alone and combined with temozolomide in patients with stable or recurrent malignant glioma.

The purpose of this study was to define the maximum tolerated dose of erlotinib and characterize its pharmaco-kinetics and safety profile, alone and with temozolomide, with and without enzyme-inducing antiepileptic drugs (EIAEDs), in patients with malignant gliomas. Patients with stable or progressive malignant primary glioma received erlotinib alone or combined with temozolomide in this dose-escalation study. In each treatment group, patients were stratified by coadministration of EIAEDs.

A phase II study of concurrent temozolomide and cis-retinoic acid with radiation for adult patients with newly diagnosed supratentorial glioblastoma.

Purpose: This Phase II study was designed to determine the median survival time of adults with supratentorial glioblastoma treated with a combination of temozolomide (TMZ) and 13-cis-retinoic acid (cRA) given daily with conventional radiation therapy (XRT).

Methods And Materials: This was a single arm, open-labeled, Phase II study. Patients were treated with XRT in conjunction with cRA and TMZ.

Phase II study of temozolomide and thalidomide with radiation therapy for newly diagnosed glioblastoma multiforme.

Purpose: The chemotherapeutic agent temozolomide (TMZ) and the antiangiogenic agent thalidomide have both demonstrated antitumor activity in patients with recurrent malignant glioma. The objectives of this study were to determine if the combined strategy of these oral agents with radiation therapy (RT) is associated with an improved median survival of patients with newly diagnosed glioblastoma multiforme and to evaluate toxicity.

Methods And Materials: Sixty-seven patients were enrolled in this trial.

Temozolomide in the treatment of recurrent malignant glioma.

Background: Options for chemotherapy at the time of recurrence in patients with malignant glioma are limited. The authors describe the efficacy and safety results of their institution's open-label, compassionate-use protocol of temozolomide for patients with recurrent malignant glioma.

Methods: Patients with recurrent malignant glioma at any time during recurrence were treated with oral temozolomide at a dose of 150 mg/m2 per day on a 5-day schedule every 28 days.
