About T cells activated against CMV
T cells are a critical component of the body's immune system and can be harnessed to counteract viral infections and some cancers. By focusing the T cells on specific proteins involved in cancers and infections, the power of the immune system can be employed to combat these diseases.T cells activated against CMV use a technology in which third-party donor derived whole blood is collected and enriched for donor T cells. The T cells are then exposed to certain antigens and the resulting activated T cells are stored for future therapeutic use in an appropriate partially human leukocyte antigen, or HLA, matched patient. CMV is a virus that can result in blindness, illness or death depending on the tissue it affects in those with weakened immune systems. The CMV program is currently in a phase 2 clinical trial (NCT01646645). For more information, please visit www.clinicaltrials.gov.
Atara Biotherapeutics has entered into an exclusive option agreement with MSK under which it has the right to acquire (pursuant to a negotiated form of license agreement) the exclusive, worldwide license rights to three clinical stage T cell therapies, including MSK's CMV T cell therapy. The option has not been exercised.
