-- Median survival (IDM-2101 versus comparator group) -- 17.3 months
versus 12.0 months.
-- Stable disease >/= 3 months -- 54 patients (86%) treated with
IDM-2101.
-- Tumor Response IDM-2101 -- One patient had complete response; one
patient had partial response.
-- 17 patients (27%) treated with IDM-2101 continued treatment for one
year with no evidence of progressive disease
-- 14 patients (22%) treated with IDM-2101 continued treatment for two
years with no evidence of progressive disease
-- Measurable immune response - 91 percent of patients treated with
IDM-2101, who were tested for immune response, had a measurable
response to at least one of the epitopes included in the vaccine
with 64 percent responding to at least three of the epitopes.
-- Toxicities attributable to the vaccine were mild and consisted
primarily of injection site reactions.
"These results further support the survival trend and safety of IDM-2101 and will serve as a basis in determining an appropriate clinical pathway for this important treatment," said Timothy P. Walbert, president and chief executive officer, IDM Pharma, Inc.
About IDM-2101
IDM-2101 includes nine CTL epitopes from four tumor associated antigens (TAA) including two proprietary native epitopes and seven modified, or analog, epitopes and one universal epitope a source of T-cell help. Tolerance to TAA, which is a failure of the immune system to recognize the cancer as diseased tissue, is broken by using these analog epitopes which enhance the potency of the T cell response. The Phase 2 IDM-2101 study has been ongoing since late 2004 and patient treatment has been completed. Long-term follow-up is ongoing for overall survival.
