Tefinostat (also known as CHR-2845) was developed as an innovative oral HDAC (histone deacetylase) inhibitor that selectively targets macrophages and monocytes – central cells of the innate immune system. Chroma Therapeutics develops tefinostat for the treatment of hematological and lymphoid malignancies. In addition, the drug is under investigation in clinical trial phase I/II for cancer-associated inflammation in hepatocellular carcinoma. The aim of this study is to find the best dose of the drug without causing side effects. Besides, Phase II of clinical trial ‘MONOCLE’ study for the treatment of chronic myelomonocytic leukemia (CMML) has been initiated and the first patient has been recruited.

Sample Use Guides

In Vivo Use Guide

Up to 5 cohorts of 3-6 patients (number is dependent on DLT occurrence) will be treated for 28 days once or twice daily (360, 480mg once daily, then 240, 360, 480mg twice daily) to determine safety and tolerability of Tefinostat and to identify the recommended dose for Phase II.
