Description: BI-2563 is a small molecule compound with potential antineoplastic activities. BI 2536 binds to and inhibits Polo-like kinase 1 (Plk1), resulting in mitotic arrest, disruption of cytokinesis, and apoptosis in susceptible tumor cell populations. Plk1, a serine/threonine-protein kinase, is a key regulator of multiple processes fundamental to mitosis and cell division.

Additional Information

Phase I study of BI2536 in patients with advanced solid tumors. Forty-four and 26 patients received each treatment schedule, respectively. The MTD of BI 2536 in the day 1 and 8 schedule was 100 mg per administration (200 mg per course). The MTD for the second dosing schedule was not determined; a 225-mg dose was well tolerated. The most frequently reported treatment-related nonhematologic adverse events were gastrointestinal events and fatigue. Hematotoxicity as the most relevant side effect was similar in both schedules; neutropenia grades 3 and 4 were observed in 16 patients (36.4%) of the day 1 and 8 schedule and 13 patients (50%) of the 24-hour infusion. Fourteen patients (32%) treated in the day 1 and 8 dosing schedule had a best overall response of stable disease. Plasma concentrations of BI 2536 increased dose proportionally, with no relevant accumulation of exposure in the day 1 and 8 dosing schedule. The average terminal half-life was 50 hours. BI 2536 administered in either treatment schedule has adequate safety in patients with advanced solid tumors, warranting further clinical investigation of polo-like kinase-1 inhibitors.

BI 2536 exhibits potent activity against malignant plasma cells and represents a novel therapy in multiple myeloma .  Cells treated with BI 2536 accumulate in the G(2)/M phase of the cell cycle causing endoduplication. The effects of BI 2536 are not abrogated when cells are cultured on extracellular matrix components, in the presence of interleukin-6, or with bone marrow stromal cells. Plk1 inhibition leads to cell death in MM cell lines and patient myeloma samples. Those data suggest that inhibition of Plk1 may have potential use as a therapeutic strategy in multiple myeloma.
