简要总结
Determine the safety, tolerability, maximum tolerated dose (MTD), and recommended Phase 2 dose (RP2D) of oral BAY1217389 given in combination with intravenous (IV) paclitaxel using an intermittent dosing schedule (2 days on / 5 days off) in subjects with advanced malignancies.
详细描述
BAY1217389 is a potent and highly selective inhibitor of monopolar spindle 1 (MPS1) kinase activity. Human MPS1 is a serine threonine kinase, which functions as a core component of the spindle-assembly checkpoint (SAC), a key surveillance mechanism that monitors the attachment of spindle microtubules to the kinetochores of the chromosomes during pro-metaphase and halts the transitions to anaphase until all chromosomes are bi-oriented, fully attached, and correctly tensed at the metaphase plate. MPS1 is expressed in the mitosis phase of the cell cycle in proliferating cells. Overexpression of MPS1 has been observed in several cancer cell lines and tumor types, including lung and breast cancers.
Established anti-mitotic drugs such as vinca alkaloids, taxanes, or epothilones activate the SAC either by destabilizing or stabilizing spindle microtubules resulting in mitotic arrest. Prolonged arrest in mitosis forces a cell either into a mitotic exit without cytokinesis or into a mitotic catastrophe leading to cell death. In contrast, MPS1 inhibitors inactivate the SAC and accelerate progression of cells through mitosis eventually resulting in severe chromosomal missegregation, mitotic catastrophe, and cell death. Consequently, MPS1 inhibition leads to failure of cells to arrest in mitosis in response to anti-mitotic drugs. Thus, the combination of microtubule-interfering agents and MPS1 inhibition strongly increases chromosomal segregation errors and cell death and therefore, constitutes an efficient strategy for selectively eliminating tumor cells.
MPS1 inhibition in combination with microtubule-interfering agents is expected to improve therapeutic efficacy of anti-mitotic drugs and to overcome paclitaxel resistance.
The primary objectives of this study are to:
- Determine the safety, tolerability, maximum tolerated dose (MTD), and recommended Phase 2 dose (RP2D) of oral BAY1217389 given in combination with intravenous (IV) paclitaxel using an intermittent dosing schedule (2 days on / 5 days off) in subjects with advanced malignancies.
- Characterize the pharmacokinetics (PK) of oral BAY1217389 and IV paclitaxel.
