Experimental Drug SS1(dsFv)-PE38 to Treat Cancer
Experimental Drug SS1(dsFv)-PE38 to Treat Cancer
Background:
This study will determine the dose of the experimental anticancer drug SS1(dsFv)-PE38
that can be given safely to patients. It will also look at how the body handles
the drug, its side effects, and its effect on the tumor. SS1(dsFv)-PE38 will be
tried in patients with solid tumors that have an antigen called mesothelin. This
is a protein that is normally produced by cells lining body cavities, but has also
been found on several types of cancer cells. The drug SS1(dsFv)-PE38 is composed
of SS1, a protein that binds tightly to mesothelin, and PE38, parts of the Pseudomonas
exotoxin (PE) protein, which can kill human cells if it gains entry to them. SS1(dsFv)-PE38
is designed to attach to mesothelin on the cancer cells and allow entry of the PE38,
which will then destroy the cells.
