In summary, the first five evaluable patients there were two confirmed durable partial responses and one patient with stable disease. No grade 3 or 4 adverse events were reported to date and the two responding patients remain on trial. This study is currently actively enrolling.
Phase 2 Trial of TPI 287 for Pancreatic Cancer Initiated
Tapestry also initiated in the third quarter a second Phase 2 trial to explore the activity of TPI 287 in advanced pancreatic cancer. The trial is a multi-center, open-label, single arm Phase 2 study for up to 65 patients with advanced stage, unresectable pancreatic cancer, who have failed a prior gemcitabine-containing chemotherapy regimen for their disease. The trial will be conducted in approximately 10 to 15 centers in the U.S., Europe and India. This study is currently actively enrolling.
Data Presented from Preclinical Studies at International Cancer Conference
Tapestry also presented preclinical data on TPI-287 at the
AACR-NCI-EORTC International Conference on Molecular Targets and Cancer
Therapeutics. The poster presentation outlined the results of a number of
different assays that confirm the Company's earlier observations that TPI
287 is less sensitive in a variety of resistant cancer cell lines to MDR1
mediated efflux than other approved taxanes. MDR1 mediated drug efflux may
be a primary cause of resistance to chemotherapy with taxanes. Also
presented was data showing that TPI 287 is retained at higher levels in
MDR1 expressing cell lines than either paclitaxel or IDN 5109, another
taxane in development purported to be active in MDR1 expressing tumors. In
addition, data was presented that demonstrated tumor growth inhibition o
