ONTAK

Reported use of ONTAK to hold T-PLL at bay after failed Campath treatment.


ONTAK

Biologic Response Modifier Agent: Denileukin Diftitox. Denileukin diftitox is a fusion protein (a combination of diphtheria toxin and interleukin-2) which selectively delivers the cell-killing activity of the diphtheria toxin to targeted cells. The lymphoma cells need to be a specific type -- they must express the high affinity IL-2 receptor on the surface of the cancer cell which then permits the IL-2 part of the fusion protein to attach/bind to the cell, halt protein synthesis and lead to cell death because of the diptheria toxin.
