(Yakult Honsha) has completed the randomized Phase II part of a clinical Phase I/II study which evaluates 4SC's epigenetic cancer compound resminostat in combination with the cancer drug sorafenib as a potential novel first-line therapy of Asian patients in Japan and South Korea with advanced liver cancer (hepatocellular cancer, HCC). In April 2011, 4SC has granted an exclusive license to Yakult Honsha, the Japanese market leader in gastro-intestinal cancer therapeutics, for the development and commercialization of resminostat in Japan. After successfully completing a Phase I safety study with resminostat in Japanese patients with advanced solid tumors in May 2014, Yakult Honsha initiated the Phase I/II study in patients with HCC, a cancer with high medical need and very limited therapeutic options, which has a particularly high incidence in Japan. In the Phase II part in 170 Asian patients with advanced HCC, resminostat in combination with sorafenib as first-line therapy in HCC did not meet the primary endpoint of statistically significant prolonged time to disease progression (TTP) compared to sorafenib monotherapy. Based on the result of the Phase II part, Yakult Honsha will not conduct a pivotal study of resminostat/sorafenib combination as first-line treatment of HCC in all- comer patients. However, patients with high expression levels of the ZFP64 biomarker at baseline seem to have longer TTP in the sorafenib/resminostat combination therapy when compared with sorafenib monotherapy. Yakult Honsha is now analyzing the results in more detail. Other ongoing as well as planned clinical trials, and in particular 4SC's anticipated Phase II CTCL trial in the EU, will not be affected. --------------------------------------------------------------------------- Information and Explanation of the Issuer to this News: About Resminostat Resminostat is an HDAC (histone deacetylase) inhibitor administered in tablet form with an innovative epigenetic mechanism of action. The compound has already been clinically tested for treating Hodgkin's lymphoma as well as liver, lung, colon, pancreatic, and biliary tract cancer. In new preclinical models, resminostat further showed promising anti-cancer and immunomodulatory activity. About liver cancer (liver cell carcinoma, hepatocellular carcinoma, HCC) With around 748,000 new cases each year, liver cancer is the fifth most common type of cancer worldwide and the third most frequent tumor-related cause of death. In the past three decades alone, the number of new cases has almost doubled. Liver cancer often remains undetected until it reaches an advanced stage, resulting in only a slim chance of recovery. The tyrosine kinase inhibitor sorafenib is the only approved drug-based first- line therapy for patients with advanced liver cancer which has been shown to offer a survival benefit in clinical trials. About the resminostat partnering agreement with Yakult Honsha for Japan 4SC granted an exclusive license to Yakult Honsha for the development and commercialization of resminostat in Japan in April 2011. 4SC has received an upfront payment from Yakult Honsha of EUR 6 million and is eligible for up to approximately EUR 127 million payable upon achieving specified milestones including clinical and regulatory events in Japan. In addition to milestone payments, Yakult Honsha will pay 4SC double-digit royalties linked to product sales of resminostat. Yakult Honsha will be responsible for all clinical requirements for resminostat development in Japan in oncology indications.
