Brief Summary:
Determine the safety, tolerability, maximum tolerated dose (MTD), and recommended Phase 2 dose (RP2D) of oral BAY 1217389 given in combination with intravenous (IV) paclitaxel using an intermittent dosing schedule (2 days on / 5 days off) in subjects with advanced malignancies.

Detailed Description:

BAY 1217389 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 BAY 1217389 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 BAY 1217389 and IV paclitaxel.

The exploratory objectives of this study are to:

  • Determine any preliminary clinical efficacy of oral BAY 1217389 given in combination with IV paclitaxel compared to paclitaxel given alone.
  • Determine pharmacodynamic (PD) target modulation effects (decrease in phosphorylated kinetochore-associated protein pKNL1 and potentially other biomarkers like activation of the p53 system) of oral BAY 1217389 in mandatory paired fresh tumor biopsies (or in mandatory paired fresh skin punch biopsies depending on the status of the subject and the accessibility of the tumor) taken on Day 2 of Cycle 1 (C1D2) and on C1D3.
  • Evaluate the effect of oral BAY 1217389 on the activation of p53 in blood samples as PD biomarker (blood samples will be taken as a mandatory procedure to monitor PD effects on C1D 4, C1D 3, and C1D 2).
  • Evaluate the effect of BAY 1217389 on levels of tumor-derived free circulating deoxyribonucleic acid (DNA) in blood samples taken before the first dose of study treatment and on C1D3, C1D8, and C1D15

Arm Intervention/treatment
Experimental: Arm 1
Experimental Treatment (combination of BAY 1217389 with paclitaxel in an intermittent dosing schedule) Expansion Cohort - Maximum tolerated dose of BAY 1217389 and Paclitaxel
Drug: BAY 1217389

BAY 1217389 will be given orally, with a starting dose of 0.25 mg twice daily, on D1, D2, D8, D9, D15 and D16 of a 28 day cycle. BAY 1217389 will be dosed in combination with paclitaxel in Arm 1 (Experimental Treatment) and from Cycle 2 onwards in Arm 2 (Standard Treatment).

After Maximum tolerated dose (MTD) has been defined, expansion cohorts will be conducted at the MTD dose of BAY 1217389 and paclitaxel following an intermittent dosing schedule as defined in the dose escalation phase. Up to 12 to 15 breast cancer (triple negative) subjects are planned to be enrolled in the expansion cohort.

In a higher dose level Cohort 4 > (or equal to) a relative bioavailability assessment of BAY 1217389 liquid capsule formulation compared to BAY 1217389 oral solution will be performed.


Drug: Paclitaxel
Paclitaxel will be given once per week IV at 90 mg/m2 on D1, D8, and D15 of a 28 day cycle. Paclitaxel will be dosed as a single-agent in Cycle 1 of Arm 2 (Standard Treatment Arm), and in combination with BAY 1217389 in Arm 1 (Experimental Treatment Arm) and from Cycle 2 onwards in Arm 2 (Standard Treatment Arm). After Maximum tolerated dose (MTD) has been defined, expansion cohorts will be conducted at the MTD dose of BAY 1217389 and paclitaxel following an intermittent dosing schedule as defined in the dose escalation phase.
