Treatment of Metastatic Melanoma With Autologous Melan-A/MART-1 Specific CTL Clones

01:29 EDT 22nd May 2013 | BioPortfolio

Summary

Most of HLA-A2 melanomas express Melan-A/MART-1 antigen and are recognized by tumor reactive Melan-A specific T lymphocytes. By using blood samples from HLA-A2 melanoma patients (stage III and IV), our goal is to produce a tumor reactive Melan-A specific T cell clones and to conduct a phase I-II clinical trial, based on the infusion of several millions to several billions of these lymphocytes to the patient, in order to induce passive immunity against this antigen. Production of the clones will be performed in the Unit for Cellular and Gene Therapy from Nantes University Hospital. Therapeutic response, safety treatment but also localization and survival of infused T cell clones will be assessed. This approach is expected to precise the ability of the clones to migrate within the tumor and to transfer specific immunity.

Medical and Biotech [MESH] Definitions

Lymphocytes, Tumor-infiltrating

Lymphocytes that show specificity for autologous tumor cells. Ex vivo isolation and culturing of TIL with interleukin-2, followed by reinfusion into the patient, is one form of adoptive immunotherapy of cancer.

Mart-1 Antigen

A melanosome-specific protein that plays a role in the expression, stability, trafficking, and processing of GP100 MELANOMA ANTIGEN, which is critical to the formation of Stage II MELANOSOMES. The protein is used as an antigen marker for MELANOMA cells.

Adoptive Transfer

Form of passive immunization where previously sensitized immunologic agents (cells or serum) are transferred to non-immune recipients. When transfer of cells is used as a therapy for the treatment of neoplasms, it is called adoptive immunotherapy (IMMUNOTHERAPY, ADOPTIVE).

Bcg Vaccine

An active immunizing agent and a viable avirulent attenuated strain of Mycobacterium tuberculosis, var. bovis, which confers immunity to mycobacterial infections. It is used also in immunotherapy of neoplasms due to its stimulation of antibodies and non-specific immunity.

Immunotherapy, Adoptive

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.

Differentiating Neurotized Melanocytic Nevi From Neurofibromas Using Melan-A (MART-1) Immunohistochemical Stain.

Context.-Neurotized melanocytic nevi and neurofibromas are common, benign cutaneous neoplasms. Usually they are histologically distinct from each other; however, neurotized melanocytic nevi and neurof...

Crystal structures of HLA-A*0201 complexed with Melan-A/MART-1(26(27L)-35) peptidomimetics reveal conformational heterogeneity and highlight degeneracy of T cell recognition.

There is growing interest in using tumor associated antigens presented by class I major histocompatibility complex (MHC-I) proteins as cancer vaccines. As native peptides are poorly stable in biologic...

Multivalent immunity targeting tumor-associated antigens by intra-lymph node DNA-prime, peptide-boost vaccination.

Active immunotherapy of cancer has yet to yield effective therapies in the clinic. To evaluate the translatability of DNA-based vaccines we analyzed the profile of T-cell immunity by plasmid vaccinati...

Memory and Effector CD8 T-cell Responses After Nanoparticle Vaccination of Melanoma Patients.

Induction of cytotoxic CD8 T-cell responses is enhanced by the exclusive presentation of antigen through dendritic cells, and by innate stimuli, such as toll-like receptor ligands. On the basis of the...

Trogocytosis Is a Gateway to Characterize Functional Diversity in Melanoma-Specific CD8+ T Cell Clones.

Trogocytosis, the transfer of membrane patches from target to immune effector cells, is a signature of tumor-T cell interaction. In this study, we used the trogocytosis phenomenon to study functional...
