Biological Therapy in Treating Patients With Primary or Advanced Glioma

2014-08-27 03:58:52 | BioPortfolio

Summary

RATIONALE: Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Interleukin-2 may stimulate a person's white blood cells to kill cancer cells in patients with primary or advanced glioma.

PURPOSE: Clinical trial to study the effectiveness of biological therapy with interleukin-2 and lymphokine-activated killer cells in treating patients who have primary, recurrent, or refractory malignant glioma.

Description

OBJECTIVES:

- Confirm the antitumor efficacy of intracavitary interleukin-2 plus autologous lymphokine-activated killer cells in patients with primary, recurrent or refractory malignant gliomas.

- Determine whether the induction of a regional, intracavitary, eosinophilia is a prognosticator of response to immunotherapy and long term survival in these patients.

OUTLINE: Patients receive cytoreductive tumor surgery and/or biopsy and implantation of intracavitary Ommaya reservoir prior to therapy induction.

Patients undergo outpatient leukapheresis on day -4 or -5, and cells are incubated ex vivo with interleukin-2 (IL-2). Lymphokine-activated killer (LAK) cells and IL-2 are infused on day 1. Bolus infusions of low-dose IL-2 are administered on days 3, 5, 8, 10, and 12, followed by a rest period on days 13-24. The course is repeated on day 25 starting with leukapheresis. Therapy courses are repeated for up to 1 year for stable disease or response to therapy. Maintenance doses repeat every 4-6 months thereafter.

Disease restaging is done every 8-12 weeks.

PROJECTED ACCRUAL: A total of 30 patients per year will be enrolled.

Medical and Biotech [MESH] Definitions

Cytolytic lymphocytes with the unique capacity of killing natural killer (NK)-resistant fresh tumor cells. They are INTERLEUKIN-2-activated NK cells that have no MAJOR HISTOCOMPATIBILITY COMPLEX restriction or need for antigen stimulation. LAK cells are used for ADOPTIVE IMMUNOTHERAPY in cancer patients.

A mucoprotein found in the cell wall of various types of bacteria. It has adjuvant and antitumor activities and has been used to augment the production of lymphokine-activated killer (LAK) cells.

Form of adoptive transfer where cells with antitumor activity are transferred to the tumor-bearing host in order to mediate tumor regression. The lymphoid cells commonly used are lymphokine-activated killer (LAK) cells and tumor-infiltrating lymphocytes (TIL). This is usually considered a form of passive immunotherapy. (From DeVita, et al., Cancer, 1993, pp.305-7, 314)

A non-receptor protein-tyrosine kinase that is expressed primarily in the BRAIN; OSTEOBLASTS; and LYMPHOID CELLS. In the CENTRAL NERVOUS SYSTEM focal adhesion kinase 2 modulates ION CHANNEL function and MITOGEN-ACTIVATED PROTEIN KINASES activity.

Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.
