Michel Sadelain

(Redirected from User:Chefmikesf/sandbox/Michel Sadelain)

Michel Sadelain (born 1960) 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.[2] 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.[2] 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.[3]

Education and career edit

Sadelain was born in 1960 in Paris, France,[4] where he earned his MD at the University of Paris, France, in 1984.[5] After obtaining his PhD in immunology at the University of Alberta in Edmonton, Canada, in 1989, he trained as a postdoctoral fellow at the Whitehead Institute for Biomedical Research, Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts.[5] While at MIT, Sadelain began his research on genetic engineering.[6] In 1994, Sadelain joined Memorial Sloan Kettering as an assistant member in the Sloan Kettering Institute, where he established programs on human hematopoietic stem cell and T cell engineering.[6] In 2008, he founded the Center for Cell Engineering at Memorial Sloan Kettering.[6] He is a past president of the American Society of Cell and Gene Therapy (2014–2015) and previously served on its board of directors from 2004 to 2007. He served as a member of the Recombinant DNA Advisory Committee (RAC) of the NIH from 2013 to 2015.[5]

Research edit

Sadelain and his team study gene transfer in hematopoietic stem cells and T cells, the regulation of transgene expression, the biology of chimeric antigen receptors, and therapeutic strategies to enhance immunity against cancer. Sadelain is a recognized leader in the conceptualization and design of synthetic receptors for antigen, which he named chimeric antigen receptors (CARs).[7] T cells can be engineered to express a CAR to acquire the ability to recognize and destroy cancer cells. Sadelain has referred to CAR T cells as a “living drug.”[8] A CAR typically comprises an antibody fragment (scFv) to recognize the cancer and a modular signaling domain to activate the T cell and promote T cell multiplication and persistence. CAR T cells are made by extracting a cancer patient’s T cells, inserting a CAR into the cell using a vector such as a gamma-retroviral or lentiviral vector, and then re-infusing the genetically instructed T cells. Sadelain's current research makes use of genome editing, which he showed makes better CAR T cells when the CAR is expressed from the TRAC locus.[9][10][11]

Sadelain’s laboratory designed second generation CARs, which are endowed with both activating and costimulatory properties, which is integral to the success of CAR therapies.[12] In 2003, Sadelain's lab identified CD19 as a target for CAR therapy in mice. Following the establishment of clinical CAR T cell manufacturing by Dr. Isabelle Rivière at MSK, Sadelain's team was the first to report on molecular complete responses induced by CD19 CAR T cells in adults with relapsed, refractory acute lymphoblastic leukemia.[13][14][15] The MSK team received FDA breakthrough designation for this treatment in 2014. The US FDA approved the first CAR therapies, targeting CD19 with second generations CARs, in 2017.[16]

Sadelain's research on “off-the-shelf” CAR T cells derived from induced pluripotent stem cells (iPSCs) is now being developed in a collaboration with Fate Therapeutics. His research with Dr. Prasad S. Adusumilli led to a collaboration with Atara Biotherapeutics, Inc. for a product candidate to treat malignant mesothelioma using mesothelin-targeted CAR T cells named icasM28z.[17] In 2013, Sadelain co-founded Juno Therapeutics Inc.[18][19]

Sadelain also designed lentiviral vectors encoding the β-globin gene for the treatment of severe hemoglobinopathies, which include β-thalassemia and sickle cell disease.[20] The MSK team was the first to treat patients with β-thalassemia in the US.[20] The history of the field and Sadelain’s contributions are narrated in the 2021 George Stamatoyannopoulos Memorial Lecture at the annual meeting of the American Society of Gene and Cell Therapy.[21][22]

Patents edit

Sadelain holds numerous patents in immunotherapy.[23] Sadelain is a named inventor on U.S. Patent No. 7446190B2 covering nucleic acids encoding chimeric T cell receptors.[24] Sadelain is also named on patent U.S. Patent No. 10,370,452 covering compositions and uses of effector T cells expressing a chimeric antigen receptor (CAR), where such T cells are derived from a pluripotent stem cell including an induced pluripotent stem cell (iPSC).[25] The patent is licensed for off-the-shelf, T-cell receptor (TCR)-less CD19 chimeric antigen receptor (CAR) T-cell product candidate known as FT819.[26][23][27]
