Summary

In this study, a combination of two T-cell directed antibodies both conjugated to a cell-killing toxin will be evaluated. Previous in vitro studies have demonstrated that this so-called immunotoxin-combination (IT-combination) acts synergistically in eliminating T cells. In a subsequent clinical pilot-study, the IT-combination has generated encouraging results when applied as third line therapy. Extensive biological and clinical responses could be noted in the absence of severe acute toxicities. Building on this experience, the current study aims at evaluating the characteristics of the IT-combination when administered in an earlier phase of the disease, i.e. as second line instead of as third line therapy.

Conditions

  • Acute Graft Versus Host Disease

Interventions

BIOLOGICAL

IT-Combination

The treatment consists of a standard dose of 4 infusions of IT-combination (4 mg/m2), given 48-hours apart over a 4-hour period. The IT-combination is a combination of two immunotoxins. One immunotoxin is a mAb anti-CD3 conjugated to recombinant ricin A chain and the other immunotoxin is a mAb anti-CD7 conjugated to recombinant ricin A chain.
