GVAX

Last updated

GVAX is a cancer vaccine composed of whole tumor cells genetically modified to secrete the immune stimulatory cytokine, granulocyte-macrophage colony-stimulating factor (GM-CSF), and then irradiated to prevent further cell division. The product exists as both autologous (patient specific) and allogeneic (non-patient specific) therapy. [1]

History

GVAX was developed around 1993 by Glenn Dranoff, a cancer researcher then at the Whitehead Institute in Cambridge, Massachusetts. [2] The therapy was initially developed by a public gene therapy company called Somatix, which was acquired in 1997 by Cell Genesys. [3] That company took the vaccine into Phase III trials in 2004 however these trials were halted in 2008 due to an apparent lack of efficacy. [4] Cell Genesys continued development, however in August 2009, due to funding difficulties, the company announced that it was merging with BioSante Pharmaceuticals. [5] In 2013 BioSante sold the GVAx program to Aduro Biotech, a company based in Berkeley, California. [6] In 2020 Aduro Biotech merged with Chinook Therapeutics, Inc. to form Chinook Therapeutics. [7]

Current development

Aduro Biotech is currently in Phase II with GVAX in pancreatic cancer, where the company is also trialing a combination of GVAX with a PD-1 inhibitor. [8]

Granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as colony-stimulating factor 2 (CSF2), is a monomeric glycoprotein secreted by macrophages, T cells, mast cells, natural killer cells, endothelial cells and fibroblasts that functions as a cytokine. The pharmaceutical analogs of naturally occurring GM-CSF are called sargramostim and molgramostim.

<span class="mw-page-title-main">Interleukin 3</span> Protein-coding gene in the species Homo sapiens

Interleukin 3 (IL-3) is a protein that in humans is encoded by the IL3 gene localized on chromosome 5q31.1. Sometimes also called colony-stimulating factor, multi-CSF, mast cell growth factor, MULTI-CSF, MCGF; MGC79398, MGC79399: after removal of the signal peptide sequence, the mature protein contains 133 amino acids in its polypeptide chain. IL-3 is produced as a monomer by activated T cells, monocytes/macrophages and stroma cells. The major function of IL-3 cytokine is to regulate the concentrations of various blood-cell types. It induces proliferation and differentiation in both early pluripotent stem cells and committed progenitors. It also has many more specific effects like the regeneration of platelets and potentially aids in early antibody isotype switching.

Hemopoietic growth factors regulate the differentiation and proliferation of particular progenitor cells. Made available through recombinant DNA technology, they hold tremendous potential for medical uses when a person's natural ability to form blood cells is diminished or defective. Recombinant erythropoietin (EPO) is very effective in treating the diminished red blood cell production that accompanies end-stage kidney disease. Erythropoietin is a sialoglycoprotein hormone produced by peritubular cells of kidney.

Sargramostim is a recombinant granulocyte macrophage colony-stimulating factor (GM-CSF) that functions as an immunostimulator.

JX-594 is an oncolytic virus is designed to target and destroy cancer cells.

Jennerex Biotherapeutics, Inc. was an American private biopharmaceutical company that developed the oncolytic viruses JX-594 and JX-929 among others. By creating oncolytic viruses that can (1) kill tumor cells directly through lysis, (2) activate the immune system by delivering genes that encode immunostimulants and by overcoming tumor cell-induced immunological tolerance, and (3) reduce tumor nutrient supply through the destruction of blood vessels, Jennerex aimed to create a novel approach to treating and possibly curing cancer.

Talimogene laherparepvec, sold under the brand name Imlygic, is a biopharmaceutical medication used to treat melanoma that cannot be operated on; it is injected directly into a subset of lesions which generates a systemic immune response against the recipient's cancer. The final four year analysis from the pivotal phase 3 study upon which TVEC was approved by the FDA showed a 31.5% response rate with a 16.9% complete response (CR) rate. There was also a substantial and statistically significant survival benefit in patients with earlier metastatic disease and in patients who hadn't received prior systemic treatment for melanoma. The earlier stage group had a reduction in the risk of death of approximately 50% with one in four patients appearing to have met, or be close to be reaching, the medical definition of cure. Real world use of talimogene laherparepvec have shown response rates of up to 88.5% with CR rates of up to 61.5%.

Myeloid-derived suppressor cells (MDSC) are a heterogeneous group of immune cells from the myeloid lineage.

Tolerogenic therapy aims to induce immune tolerance where there is pathological or undesirable activation of the normal immune response. This can occur, for example, when an allogeneic transplantation patient develops an immune reaction to donor antigens, or when the body responds inappropriately to self antigens implicated in autoimmune diseases. It must provide absence of specific antibodies for exactly that antigenes.

Dinutuximab and dinutuximab beta are monoclonal antibodies used as a second-line treatment for children with high-risk neuroblastoma. Each antibody is made of both mouse and human components and targets glycolipid GD2, expressed on neuroblastoma cells and on normal cells of neuroectodermal origin, including the central nervous system and peripheral nerves. They differ in that dinutuximab is manufactured using mouse cells, and dinutuximab beta is manufactured using hamster cells. The dosing regime differs, and dinutuximab is given in combination with granulocyte-macrophage colony stimulating factor (GM-CSF), interleukin-2 (IL-2) and 13-cis-retinoic acid (RA), while dinutuximab beta can be given alone.
