Curis, Inc. announced that the first patient has been treated in a Phase I clinical study of CUDC-907 in patients with relapsed or refractory lymphoma or multiple myeloma. CUDC-907 is an orally-administered first-in-class small molecule drug candidate that has been designed as a dual inhibitor of phosphatidylinositol-3-kinase (PI3K) and histone deacetylase (HDAC). As a result of this clinical advance, Curis is entitled to receive an additional $350,000 in milestone payments under the terms of its agreement with The Leukemia and Lymphoma Society (LLS).

This clinical trial is designed as a standard dose escalation study in which CUDC-907 will be orally administered to patients with relapsed or refractory lymphoma or multiple myeloma at up to four study centers in the United States. The primary objectives of the study are to determine the maximum tolerated dose and recommended oral dose of CUDC-907 for Phase II study. The secondary objectives of this study are to assess safety and tolerability, to assess pharmacokinetics, to evaluate biomarker activity and to assess preliminary anti-cancer activity of CUDC-907 in this patient population.

In the absence of dose limiting toxicity, each patient will receive oral CUDC-907 once daily for a minimum of 21 days of continuous daily dosing (1 cycle), and may continue to receive additional cycles of study treatment until disease progression or other treatment discontinuation criteria are met. Additional details about this study can be found on clinicaltrials.gov (NCT01742988).
