About
The purpose of this trial is to study A-dmDT390-bisFv(UCHT1) in combination with ionizing irradiation for the treatment of stage IV melanoma, a disease that is essentially incurable with median overall survival periods that range from 8-16 months.
Full description
A-dmDT390-bisFv(UCHT1) (Resimmune™), an anti-T cell immunotoxin is currently being studied as a treatment for cutaneous T cell lymphoma and other CD3+ malignant diseases (FDA IND Number: 100712, Scott and White Protocol 071163). During the course of this study, data accumulated that Resimmune could be acting as an immunomodulator. This was based on the observation that four out of six partial responses converted to complete responses at times ranging between 6 and 24 months following the completion of the 4-day treatment protocol and no other treatment took place.
The purpose of this trial is to test the hypothesis that Resimmune can act as an immunomodulator of late stage metastatic melanoma when combined with palliative radiation to induce the priming of activated T cells with tumor antigens. The primary objective of this study is to determine the safety of combining Resimmune with palliative radiation therapy in patients with stage IV melanoma. A secondary objective is to document the tumor response and duration of response at irradiated and unirradiated sites (the abscopal effect). An additional secondary objective is to determine if T cell activation occurs following administration of A-dmDT390-bisFv(UCHT1) and local radiation to a metastatic lesion of melanoma.
