MART-1/Melan-A Melanoma Monotherapy <strong>Ph</strong>ase I No tumor regression observed. An enhancement of<br />

the cytotoxic activity against MART-1/Melan-A<br />

was detected<br />

MART-1/Melan-A, Melanoma Combinatorial <strong>Ph</strong>ase I Six of 12 patients developed a positive skin test<br />

gp100, and<br />

evaluated via IFN-gamma release assay and<br />

ELISPOT assay, so did 11 of 12 patients analyzed<br />

by MHC-peptide tetramer assay<br />

MART-1/Melan-A Melanoma Monotherapy <strong>Ph</strong>ase I Ten of 22 patients had response to peptide-pulsed<br />

targets or tumor cells by ELISA assay after<br />

vaccination. Twelve of 20 patients had response by<br />

ELISPOT. Immune response by ELISA correlated<br />

with prolonged relapse-free survival<br />

MART-1/Melan-A Melanoma Combinatorial <strong>Ph</strong>ase II Out of 20 patients, two patients had a complete<br />

(IL-12)<br />

response, five had a minor or mixed response, and<br />

four patients had stable disease. There was a<br />

correlation between the magnitude of the increase<br />

in MART-1/Melan-A–specific cells and clinical<br />

response<br />

MART-1/Melan-A, Melanoma Combinatorial <strong>Ph</strong>ase I/II Peptides were more effective when given with the<br />
