Steven A. Rosenberg (born 2 August 1940 [1] ) is an American cancer researcher and surgeon, chief of Surgery at the National Cancer Institute in Bethesda, Maryland and a Professor of Surgery at the Uniformed Services University of Health Sciences and the George Washington University School of Medicine and Health Sciences. He pioneered the development of immunotherapy that has resulted in the first effective immunotherapies and the development of gene therapy. He is the first researcher to successfully insert foreign genes into humans.
Rosenberg was born in 1940, in the Bronx, the youngest of three children of Jewish immigrants from Poland, [2] [1] who owned a luncheonette. He met his wife to be, Alice O’Connell during his residency at Boston’s Peter Bent Brigham Hospital, who was the chief nurse at the time. They got married in 1968 and have three daughters. [1]
He is credited with developing the use of IL-2 and immune cells for the treatment of patients with melanoma in a procedure termed adoptive cell transfer. [3] He has shown that expanding immune cells (known as tumor infiltrating lymphocytes) in the lab can be used to treat patients with melanoma and has published two important studies describing their use. The first in 2002, demonstrated that some patients with advanced melanoma can be treated to complete remission with a combination of chemotherapy, immune cells and high doses of IL-2. [4] The second, in 2006, demonstrated that the receptor of T cells can be transferred to immune cells and in combination with chemotherapy and high doses of IL-2 can be used to treat patients with melanoma. [5] Although, this was the first time that the T cell receptor was used for gene therapy, it was not the first time that gene therapy was used in cancer. Tumor cells modified with a gene for immune growth factors such as GM-CSF, had been used many years previously and continue to be used, although the efficacy of GM-CSF modified tumor lines as a cancer vaccine remain extremely modest, at best. [6] There has been some debate as to the role of the T cells in treating the cancer in these studies as high-dose IL-2 and chemotherapy have also been shown to have anti-cancer properties. Nevertheless, the combination of chemotherapy, T cells and high-dose IL-2 was shown to be effective even in patients who had previously failed high-dose IL-2 treatment.
Rosenberg has pioneered the use of adoptive immunotherapy.
Rosenberg graduated from the Bronx High School of Science. He received his B.A. (biology, 1961) and M.D. (1964) degrees from Johns Hopkins University. [1] He served a surgical internship and residency at the Peter Bent Brigham Hospital, completing it in 1974. During his residency he also earned a Ph.D. in biophysics from Harvard University with thesis titled The proteins of human erythrocyte membranes (in 1968/1969). [1] Following the completion of his surgical residency, he became the Chief of Surgery at the National Cancer Institute, a position he continues to hold. [1] His research has focused on the immunotherapy of cancer.
Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system. Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies. Immunotherapy is under preliminary research for its potential to treat various forms of cancer.
A cancer vaccine, or oncovaccine, is a vaccine that either treats existing cancer or prevents development of cancer. Vaccines that treat existing cancer are known as therapeutic cancer vaccines or tumor antigen vaccines. Some of the vaccines are "autologous", being prepared from samples taken from the patient, and are specific to that patient.
Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15.5–16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 is part of the body's natural response to microbial infection, and in discriminating between foreign ("non-self") and "self". IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes. The major sources of IL-2 are activated CD4+ T cells and activated CD8+ T cells. Put shortly the function of IL-2 is to stimulate the growth of helper, cytotoxic and regulatory T cells.
Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving the immune system's natural ability to fight the disease. It is an application of the fundamental research of cancer immunology and a growing subspecialty of oncology.
Virotherapy is a treatment using biotechnology to convert viruses into therapeutic agents by reprogramming viruses to treat diseases. There are three main branches of virotherapy: anti-cancer oncolytic viruses, viral vectors for gene therapy and viral immunotherapy. These branches use three different types of treatment methods: gene overexpression, gene knockout, and suicide gene delivery. Gene overexpression adds genetic sequences that compensate for low to zero levels of needed gene expression. Gene knockout uses RNA methods to silence or reduce expression of disease-causing genes. Suicide gene delivery introduces genetic sequences that induce an apoptotic response in cells, usually to kill cancerous growths. In a slightly different context, virotherapy can also refer more broadly to the use of viruses to treat certain medical conditions by killing pathogens.
Ipilimumab, sold under the brand name Yervoy, is a monoclonal antibody medication that works to activate the immune system by targeting CTLA-4, a protein receptor that downregulates the immune system.
Cancer immunology (immuno-oncology) is an interdisciplinary branch of biology and a sub-discipline of immunology that is concerned with understanding the role of the immune system in the progression and development of cancer; the most well known application is cancer immunotherapy, which utilises the immune system as a treatment for cancer. Cancer immunosurveillance and immunoediting are based on protection against development of tumors in animal systems and (ii) identification of targets for immune recognition of human cancer.
Chemoimmunotherapy is chemotherapy combined with immunotherapy. Chemotherapy uses different drugs to kill or slow the growth of cancer cells; immunotherapy uses treatments to stimulate or restore the ability of the immune system to fight cancer. A common chemoimmunotherapy regimen is CHOP combined with rituximab (CHOP-R) for B-cell non-Hodgkin lymphomas.
Tumor-infiltrating lymphocytes (TIL) are white blood cells that have left the bloodstream and migrated towards a tumor. They include T cells and B cells and are part of the larger category of ‘tumor-infiltrating immune cells’ which consist of both mononuclear and polymorphonuclear immune cells, in variable proportions. Their abundance varies with tumor type and stage and in some cases relates to disease prognosis.
Vaccine therapy is a type of treatment that uses a substance or group of substances to stimulate the immune system to destroy a tumor or infectious microorganisms such as bacteria or viruses.
Immunotransplant is a maneuver used to make vaccines more powerful. It refers to the process of infusing vaccine-primed T lymphocytes into lymphodepleted recipients for the purpose of enhancing the proliferation and function of those T cells and increasing immune protection induced by that vaccine.
Adoptive cell transfer (ACT) is the transfer of cells into a patient. The cells may have originated from the patient or from another individual. The cells are most commonly derived from the immune system with the goal of improving immune functionality and characteristics. In autologous cancer immunotherapy, T cells are extracted from the patient, genetically modified and cultured in vitro and returned to the same patient. Comparatively, allogeneic therapies involve cells isolated and expanded from a donor separate from the patient receiving the cells.
Autologous immune enhancement therapy (AIET) is a treatment method in which immune cells are taken out from the patient's body which are cultured and processed to activate them until their resistance to cancer is strengthened and then the cells are put back in the body. The cells, antibodies, and organs of the immune system work to protect and defend the body against not only tumor cells but also bacteria or viruses.
Molecular oncology is an interdisciplinary medical specialty at the interface of medicinal chemistry and oncology that refers to the investigation of the chemistry of cancer and tumors at the molecular scale. Also the development and application of molecularly targeted therapies.
Urelumab is a fully human, non‐ligand binding, CD137 agonist immunoglobulin‐γ 4 (IgG4) monoclonal antibody. It was developed utilizing Medarex's UltiMAb(R) technology by Bristol-Myers Squibb for the treatment of cancer and solid tumors. Urelumab promotes anti-tumor immunity, or an immune response against tumor cells, via CD137 activation. The application of Urelumab has been limited due to the fact that it can cause severe liver toxicity.
James Patrick Allison is an American immunologist and Nobel laureate who holds the position of professor and chair of immunology and executive director of immunotherapy platform at the MD Anderson Cancer Center at the University of Texas.
Eftilagimod alpha is a large-molecule cancer drug being developed by the clinical-stage biotechnology company Immutep. Efti is a soluble version of the immune checkpoint molecule LAG-3. It is an APC Activator used to increase an immune response to tumors, and is administered by subcutaneous injection. Efti has three intended clinical settings:
T lymphocytes are cells of the immune system that attack and destroy virus-infected cells, tumor cells and cells from transplanted organs. This occurs because each T cell is endowed with a highly specific receptor that can bind to an antigen present at the surface of another cell. The T cell receptor binds to a complex formed by a surface protein named "MHC" and a small peptide of about 9 amino-acids, which is located in a groove of the MHC molecule. This peptide can originate from a protein that remains within the cell. Whereas each T cell recognizes a single antigen, collectively the T cells are endowed with a large diversity of receptors targeted at a wide variety of antigens. T cells originate in the thymus. There a process named central tolerance eliminates the T cells that have a receptor recognizing an antigen present on normal cells of the organism. This enables the T cells to eliminate cells with "foreign" or "abnormal" antigens without harming the normal cells.
Michel Sadelain is an genetic engineer and cell therapist at Memorial Sloan Kettering Cancer Center, New York, New York, where he holds the Steve and Barbara Friedman Chair. He is the founding director of the Center for Cell Engineering and the head of the Gene Transfer and Gene Expression Laboratory. He is a member of the department of medicine at Memorial Hospital and of the immunology program at the Sloan Kettering Institute. He is best known for his major contributions to T cell engineering and chimeric antigen receptor (CAR) therapy, an immunotherapy based on the genetic engineering of a patient's own T cells to treat cancer.
Cellular adoptive immunotherapy is a type of immunotherapy. Immune cells such as T-cells are usually isolated from patients for expansion or engineering purposes and reinfused back into patients to fight diseases using their own immune system. A major application of cellular adoptive therapy is cancer treatment, as the immune system plays a vital role in the development and growth of cancer. The primary types of cellular adoptive immunotherapies are T cell therapies. Other therapies include CAR-T therapy, CAR-NK therapy, macrophage-based immunotherapy and dendritic cell therapy.
