41OA phase I study of CPI-0610, a bromodomain and extra terminal protein (BET) inhibitor in patients with relapsed or refractory lymphoma

Background: NF-kB has been found to be constitutively activated in many lymphomas, such as diffuse large B-cell lymphomas (DLBCL), particularly the ABC subgroup. In preclinical studies, CPI-0610, a BET specific small molecule inhibitor, results in downregulation of NF-κB signaling activity, accompanied by loss of viability of ABC-DLBCL cell lines. Here we report the results from the first-in human Phase 1 study of CPI-0610 in patients with relapsed or refractory lymphomas (NCT01949883).
