CellAct Pharma Advances Phase I Clinical Trial of Topoisomerase Inhibitor in Cancer

19-Oct-2009 - Germany

CellAct Pharma announced the continued enrollment of patients with advanced cancer into a Phase I clinical trial of CAP7.1. This follows a preliminary study in children with neuroblastoma. CAP7.1 is CellAct‘s lead small molecule candidate and is designed to target topoisomerase II in cancer cells and induce cell death.

The trial is an open-label, dose-escalation study evaluating the safety and pharmacokinetics of CAP7.1 in patients with solid tumors that are refractory to standard therapies. It will enroll 3 to 6 patients per cohort during the dose escalation phase of the study to a total of 30 patients.

The primary endpoint of the study will be safety, but patients also will be evaluated for anti-tumor activity as well as tolerance of the drug in order to determine the optimal schedule and level of dosing. The trial has been initiated in a specialized center for oncology in Germany. Data from the study is anticipated by mid 2010.

"CAP7.1 is a prodrug of Etoposide that has potential to treat multiple types of cancer, particularly lung and cancers with Multi Drug Resistance. The potential of CAP7.1 has been shown in a preliminary study in children with neuroblastoma, who tolerated the drug well and showed a preliminary therapeutic response,” stated Nalân Utku, M.D., Managing Director of CellAct. "The ability of CAP7.1 to inhibit growth of tumors in preclinical studies coupled with its bioavailability makes it an appealing product candidate to advance into human clinical trials."

CAP7.1 is designed as a prodrug of Etoposide, which inhibits topoisomerase II. In preclinical and clinical studies to date, CAP7.1 has demonstrated a unique mechanism of action independent of Etoposide effects, which is being further analyzed. CellAct has received a €0.7 million grant from the German ministry for education and science (Bmbf) to support this program.
