4SC to Highlight the Potential of its Oncology Compounds at the 22nd EORTC-NCI-AACR Symposium 'on Molecular Targets and Cancer Therapeutics'

(PresseBox) ( Planegg-Martinsried, )
4SC (Frankfurt, Prime Standard: VSC), a drug discovery and development company focused on autoimmune and cancer indications, today announced that it will present four posters and respective abstracts that highlight the development of its lead oncology compound resminostat and several preclinical drug candidates at the 22nd EORTC-NCI-AACR symposium from 16 - 19 November, 2010 in Berlin, Germany. These data include an overview on the clinical development activities of the pan-HDAC inhibitor resminostat, currently in Phase II trials in hepatocellular cancer and Hodgkin's lymphoma, a profile of its second, selective-HDAC inhibitor 4SC-202 and an introduction to 4SC-207, an anti-mitotic cell cycle blocker.

'Our presence at EORTC underlines our commitment to developing oncology candidates that will offer an improved and targeted standard of care for cancer patients,' said Bernd Hentsch, Chief Development Officer, 4SC. 'We have focused our resources over the last three years in order to establish a pipeline of clinical and preclinical compounds targeting molecular pathways for various tumour types and hold the promise to provide more tailored treatment for patients.'

About Resminostat (4SC-201)

Resminostat (4SC-201) is an oral pan-histone-deacetylase (HDAC) inhibitor. HDAC inhibitors modify the DNA structure of tumour cells to cause their differentiation and programmed cell death (apoptosis) and are therefore considered to offer a mechanism of action that has the particular potential to halt tumour progression and induce tumour regression. Resminostat is currently in a Phase II study as a second line treatment for advanced hepatocellular carcinoma and as a third-line treatment in Hodgkin's lymphoma. In a completed Phase I trial in patients with various different cancer types, stable disease was achieved in over 50% of the patients, whilst the treatment was well tolerated and showed a positive, differentiating pharmacological profile to other drugs in this class.

About 4SC-202

This candidate is an oral, selective Class I histone-deacetylase (HDAC) inhibitor. In contrast to the further advanced pan- HDAC inhibitor resminostat it belongs to a different chemical class with a selective inhibitory effect on Class I HDAC enzymes. 4SC-202 enables a dual attack on malignant cancer cells as it exhibits a special anti-mitotic effect, which makes this candidate particularly suitable for the treatment of cancer types characterised by rapid tumour cell proliferation.

About 4SC-207

4SC-207 is a novel, orally available cell-cycle blocker (CCB) for the treatment of chemotherapy resistant tumours. This anti-mitotic compound inhibits the cell division of actively proliferating tumour cells. In preclinical testing, apoptosis was observed in dividing cancer cells only, rather than in non-proliferating cells. A prominent characteristic of 4SC-207 is its resistance breaking activity. 4SC-207 affects cancer cells which are already resistant to taxanes and alkaloids.
