Parameter	No. of patients	%
Stable disease	11	73
Progression	3	20

Of the 15 patients who received more than two treatments, 11 had stable disease, 3 experienced tumor progression, and 1 had partial response. Nine patients displayed a reduction in CA 19-9 tumor markers, in five of which it was greater than 20%.
