Additional Information

4SC-202 is an orally administered selective class I HDAC inhibitor. 4SC-202 demonstrates a particularly strong anti-mitotic activity. 4SC-202 enables a dual attack on malignant cancer cells and is therefore not a back-up compound for resminostat. Its strong, specific anti-mitotic effect could make this candidate particularly suitable for the treatment of cancer types that exhibit high rates of cell division. 4SC-202, currently being developed by A German Company called 4SC,  is in the Phase I TOPAS study in order to evaluate the safety, pharmacokinetics and clinical efficacy of the orally administered compound in patients with advanced hematological indications, including acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), multiple myeloma (MM), myelodysplastic syndrome (MDS) and lymphomas (source: http://www.4sc.de/product-pipeline/clinical/4SC-202).
