At MSK, we're fighting cancer with genetically engineered immune cells built just for you.

Learn how our scientists are using this innovative immunotherapy — a type of living drug — to offer patients hope.

What is CAR T?

Your own body is one of your best defenses against cancer. Memorial Sloan Kettering scientists are learning how to harness the power of the body’s immune system to fight cancer, an approach called immunotherapy.

Racing to the front of the pack is a type of immunotherapy called chimeric antigen receptor (CAR) T cell therapy. In this approach, immune cells are removed from a patient, armed with new proteins that allow them to recognize cancer, and given back to the patient in large numbers. These cells persist in the body, becoming “living drugs.”

MSK scientists pioneered this approach, and they are working hard to improve and expand it. See how this treatment works.

Fast CAR T Facts
  • MSK is currently running CAR T-focused clinical trials for several different types of cancer.
  • MSK scientists pioneered CAR T cell therapy for cancer.
  • More than 80 percent of acute leukemia patients treated with CD19-directed CARs at MSK have seen their cancer regress.
  • MSK scientists were the first to show that CD19 was a good target for CAR T cells.
  • MSK scientists are exploring ways to make CAR T cell therapy safer, with fewer side effects.

Expert Patient Care

Our doctors and nurses have unparalleled expertise in caring for patients who are receiving this treatment. There are risks associated with receiving CAR T cells, but our clinicians — including members of the Cellular Therapeutics Center and the Bone Marrow Transplant Service — have vast experience in managing side effects, which are usually reversible.

CAR T cell therapy has proven very effective at treating acute lymphoblastic leukemia (ALL) in both children and adults. This type of blood cancer is usually treated successfully with chemotherapy, but in some cases conventional approaches do not work. That’s when CAR T cell therapy can be a patient’s best option.

Success Story: Ezzy

When chemotherapy couldn’t get Esmeralda Pineda’s pediatric leukemia under control, doctors at Memorial Sloan Kettering turned to immunotherapy. The successful treatment wiped out all signs of her disease, and one year later, she’s still cancer free. Read Ezzy’s story

Success Story: Karen

When avid golfer Karen Koehler was sidelined by cancer, CAR T immunotherapy got her back in full swing. Read Karen’s story

CAR T cells are also being explored as a treatment for several other types of cancer, including lymphoma, lung cancer, breast cancer, mesothelioma, ovarian cancer, and multiple myeloma. To search for an open CAR T trial at MSK, visit our clinical trial database.

Putting CARs on the Road

The roots of CAR T therapy stretch back nearly 30 years, to the work of a young immunologist named Michel Sadelain, who is now the Director of the Center for Cell Engineering at MSK.

In the early 1990s, the techniques to introduce genes into cells were just being developed. Dr. Sadelain wanted to use the new techniques to engineer T cells, giving them souped-up capabilities.

“At the time it sounded very pipe dream,” one of Dr. Sadelain’s doctoral thesis advisers told the New York Times. But Dr. Sadelain “believed in his approach and he pursued it relentlessly.” 

An important goal of this work was to prove to myself, and maybe to mankind, that our own cells can be harnessed, modified, and transformed into very effective drugs.

A decade later, in 2002, Dr. Sadelain and his MSK colleagues, including Isabelle Rivière and Renier Brentjenspublished a now seminal article showing that T cells engineered with a chimeric antigen receptor could kill tumor cells and persist in the body. They were also the first ones to show that targeting a marker called CD19, found on the surface of blood cells, was a good way to kill leukemia and lymphoma.

Center for Cell Engineering

It takes a particular kind of chutzpah to look at a cell — perhaps the greatest evolutionary invention of all time — and see room for improvement. The scientists in MSK’s Center for Cell Engineering are leaders in pushing the boundaries of the possible.

The FDA granted CD19 CAR T cells a Breakthrough Therapy designation for relapsed or refractory ALL in 2014. “CAR T cells are making history, beyond any doubt,” Dr. Sadelain says.

Manufacturing Living Drugs

Using cells as drugs requires a sterile facility that can manufacture these sophisticated cellular products under strict controls. MSK has an entire core facility devoted to this vital task.

Cell Therapy and Cell Engineering Facility

MSK’s Cell Therapy and Cell Engineering Facility, led by immunologist Isabelle Rivière, is responsible for making cellular therapies for use in clinical trials at MSK.

Cellular Therapeutics Center

Administering investigational CAR T cells safely and effectively is the job of members of MSK’s Cellular Therapeutics Center, led by physician-scientist Renier Brentjens. From designing clinical trials to working with other centers to establish CAR T programs, the members of this center are leaders in the clinical application of CARs.
