4SC AG's Resminostat Meets Primary Efficacy Endpoint in Phase II Trial in Hodgkin's Lymphoma (HL)

PLANEGG-MARTINSRIED, Germany--(BUSINESS WIRE)-- 4SC AG (FWB:VSC.f - News), a discovery and development company of targeted small molecule drugs for autoimmune diseases and cancer, today announced positive topline data from its Phase II SAPHIRE trial with resminostat, its oral pan HDAC inhibitor, in patients with relapsed/refractory Hodgkin's Lymphoma (HL). Resminostat monotherapy exhibited substantial anti-tumour activity, including complete and partial tumour responses. Analysis of tumour response assessments revealed that the study achieved its primary endpoint. Furthermore the study verified the drug to be safe and well tolerated in this advanced stage patient population.

In June 2011 the SAPHIRE trial completed patient enrolment. 33 patients have been evaluated for tumour response which, according to the study protocol, represents the targeted number of patients required for efficacy analyses. Central assessment of patient tumour data by an independent expert review board revealed objective tumour responses in 11 patients, constituting a 33.3% overall response rate (ORR) and thereby successfully achieving the pre-defined requirements of the primary endpoint of the study. An additional 7 patients achieved stabilization of their disease and thus a clinical benefit as well. The ORR of 33.3% together with the clinical benefit recorded in total for 54.5% of the patients (disease control rate) demonstrates the substantial anti-tumour activity of resminostat monotherapy in an advanced and heavily pre-treated Hodgkin's Lymphoma patient population for which there is currently no established standard therapy available. Prior to study entry, the patients enrolled received a median of 6 treatments consisting of various chemo- and radiation therapies including autologous stem cell transplantation in 57% of the cases.

Final data from this trial, including secondary endpoints, will be presented at an upcoming international scientific conference.
