ACTIVE MOIETY
The EC1456 poster shows that EC1456 is generally well tolerated in previously treated cancer patients, with no treatment-related deaths, SAE's, dose modifications, or Grade 4 toxicities on either schedule. There is also no evidence of cumulative or late emerging toxicity, thus far. Grade 1-2 toxicities include nausea, vomiting, stomatitis, abdominal pain, constipation, diarrhea, paresthesia, and fatigue. Cohort expansions are continuing at 4.5 mg/m2 (weekly schedule) and 2.5 mg/m2 (biweekly schedule). Anti-tumor activity with EC1456 is suggested by prolonged stable disease in FR+ patients: 11/20 patients had stable disease as their best study response. EC1456 shows a dose-dependent PK profile that has prolonged drug concentration above IC50 and is more favorable than the 1st generation SMDC, vintafolide.
