Says Wolchok’s Lab: we’ve got something that “Eliminates-Advanced-Tumors Without Off-Target Off-Target Toxicities in a Melanoma Preclinical Model”… Quite an AACR’17 attention grabber!

All we know so far is that the MSKCC/Wolchok.Lab will be presenting on 4-3-17 at AACR’17 an abstract titled, “Targeting Phosphatidylserine in Combination with Adoptive T Cell Transfer Eliminates Advanced Tumors without Off-Target Toxicities in a Melanoma Preclinical Model”.

We only know the TITLE at this point. On 3-1-17, AACR’17 will publish the Abstract Summaries at http://www.aacr.org/Meetings/Pages/MeetingDetail.aspx?EventItemID=105&DetailItemID=539 . This has obviously be known for some time by Mem.Sloan & Peregrine – the deadline for “regular abstracts” was Nov. 17th, and for “late breakers” was Jan. 12th.

The New PPHM+Mem.Sloan/Wolchok PS-Targeting Study revealed-via AACR’17 Abstracts – I’m learning more about this cancer immunotherapy approach called “Adoptive Cell Transfer (ACT)” that The Wolchok Lab & Peregrine are working on. It’s a bigger deal than I thought...

“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 cancer immunotherapy, T cells are extracted from the patient, genetically modified and cultured in vitro and returned to the same patient.

**From 3-2014 Immunotherapy article: “Cancer immunotherapy, particularly adoptive cell transfer (ACT), has shown great promise in the treatment of patients with late-stage disease, including those who are refractory to std. Therapies” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4372895

**Through the support from SEAN PARKER, Stand Up To Cancer (SU2C) and the Cancer Research Institute (CRI) formed an Immunology Research Dream Team dedicated to cancer immunology: “Immunologic Checkpoint Blockade & Adoptive Cell Transfer in Cancer Therapy.” The Immunotherapy Dream Team is focused on 2 approaches for this translational cancer research project, which will unite laboratory & clinical efforts towards the immunological treatment, control, and prevention of cancer.
The 1st is investigating blockades (by inhibitory molecules called “checkpoints”) of T lymphocytes’ inhibitory receptors, which block immune responses; and the use of antibodies to remove the checkpoints, once again allowing white blood cells called T lymphocytes to kill the cancer cells.
Second, the Immunotherapy Dream Team is pursuing multiple Adoptive Cell Transfer (ACT) approaches, which increase immunity.”
DREAM TEAM LEADERSHIP: 10 scientists, incl. MSKCC’s Jedd D. Wolchok & Michel Sadelain.

**12-12-2012: MSK Researchers Jedd Wolchok & Michel Sadelain Appointed to “Stand Up To Cancer” Immunology “Dream Team”
TWO APPROACHES TO ATTACKING CANCER:
The Immunology Dream Team will pursue 2 research techniques.
The 1st, being led by Dr. Wolchok, involves studying how a type of white blood cell called a T lymphocyte, or T cell, can kill cancer cells. Sometimes, the natural function of the T lymphocyte is blocked or not activated enough to attack cancer cells, allowing the cancer to grow ["Immunologic Checkpoint Blockade"]. Part of the Dream Team’s focus will be to investigate ways to ensure that the T lymphocytes work properly in recognizing and killing cancer cells.
The 2nd immunotherapy approach, known as Adoptive Cell Transfer (ACT), involves removing some of a patient’s T cells, enhancing their cancer-fighting abilities and growing them in the laboratory, and then infusing the enhanced cells back into the patient. This can provide a patient with an army of immune cells specifically programmed to fight against cancer. This part of the Dream Team’s research, led by Dr. Sadelain, will investigate several ways to use ACT as a cancer therapy.
