Brief Summary:

The primary objective of this study is:

- Determine the safety, tolerability, maximum tolerated dose (MTD) or recommended Phase II dose (RP2D) of BAY 1436032 in patients with isocitrate dehydrogenase-1 (IDH1)-R132X-mutant advanced solid tumors.

The secondary objectives of this study are:

  • Evaluate the pharmacokinetics (PK) of BAY1436032 in patients with IDH1-R132X-mutant advanced solid tumors.
  • Evaluate the effect of a standard high-fat, high calorie meal on the PK of BAY1436032.
  • Assess pharmacodynamic (PD) effects and evidence of clinical efficacy associated with BAY1436032 administration in patients with IDH1-R132X-mutant advanced solid tumors.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-label, Non-randomized, Multicenter Phase I Study to Determine the Maximum Tolerated or Recommended Phase II Dose of Oral Mutant IDH1 Inhibitor BAY1436032 and to Characterize Its Safety, Tolerability, Pharmacokinetics and Preliminary Pharmacodynamic and Anti-tumor Activity in Patients With IDH1-R132X-mutant Advanced Solid Tumors
Actual Study Start Date : May 26, 2016
Actual Primary Completion Date : November 8, 2018
Estimated Study Completion Date : June 30, 2020

Arm Intervention/treatment
Experimental: BAY1436032

Dose escalation: Patients with any type of IDH1-R132X-mutant solid tumor may be eligible for enrollment. A minimum of 3 patients per cohort will be treated. If dose limiting toxicities (DLTs) occur, Bayesian dose-DLT modeling will be performed to help guide dosing decisions and to identify the maximum tolerated dose (MTD). If the MTD is not reached, a recommended phase II dose (RP2D) will be chosen based on available safety, tolerability, PK, PD and clinical efficacy data.

Dose expansion: The dose and schedule that was determined to be most appropriate in the dose escalation part of the study, which may be the MTD and / or the RP2D, will be used. Cohorts will consist of patients with the following IDH-R132X-mutant tumor types: (1) anaplastic glioma; (2) glioblastoma; (3) intrahepatic cholangiocarcinoma; (4) tumor types other than those in Cohorts 1-3.

Drug: BAY1436032
The selected starting dose of BAY1436032 is 300 mg/day (150 mg BID) to be administered orally continuously in tablet form in 21-day cycles. Adjustments to this schedule may be made if warranted by information collected during the course of the study. The maximum feasible dose of BAY1436032 is expected to be 3000 mg/day.




Primary Outcome Measures :
  1. Maximum tolerated dose (MTD) of BAY1436032 [ Time Frame: 21 days ]
    MTD is defined as the maximum dose at which the predicted incidence of DLTs during Cycle 1 (DLT evaluation period) is ≤25%.

  2. Number of participants with adverse events as a measure of safety and tolerability of BAY1436032 [ Time Frame: Up to 30 months ]
    Safety and tolerability variables will include AEs, laboratory safety tests, ECGs, and vital signs.

  3. Recommended Phase II Dose (RP2D) of BAY1436032 [ Time Frame: Up to 20 months ]
    If the MTD is not reached, the primary variable will be the RP2D, defined based on all available safety, PK, PD, biomarker, and efficacy data collected after the start of BAY1436032 treatment.


Secondary Outcome Measures :
  1. Objective response rate (partial and complete response) [ Time Frame: Up to 30 months ]
    Assessed by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) or for gliomas Response Assessment in Neuro-Oncology (RANO)

  2. Duration of response [ Time Frame: Up to 30 months ]
  3. Progression free survival (PFS) [ Time Frame: Up to 30 months ]
    For expansion part only

  4. Cmax of BAY1436032 [ Time Frame: on C1D-2 and C1D1 ]
  5. AUC(0-12) of BAY1436032 [ Time Frame: on C1D-2 and C1D1 ]
  6. AUC(0-24) of BAY1436032 [ Time Frame: on C1D-2 and C1D1 ]
  7. C(max,md) of BAY1436032 [ Time Frame: on C1D15 ]
  8. AUC(0-12)md of BAY1436032 [ Time Frame: on C1D15 ]
  9. Change of 2-hydroxyglutarate (2-HG) concentration in plasma from baseline [ Time Frame: Up to 30 months ]
  10. Change of 2-hydroxyglutarate (2-HG) concentration in urine from baseline [ Time Frame: Up to 30 months ]

Criteria

Inclusion Criteria:

  • Male or female patients ≥ 18 years of age
  • Patients with a histologically confirmed solid tumor:

    • Tumor must harbor an IDH1-R132X mutation

    • Patients with advanced cancer who are refractory to, have demonstrated intolerance to, or have refused access to, available standard therapies
    • Glioma patients must have completed chemoradiotherapy at least 12 weeks prior to screening and their baseline scan
  • Patient must be able to provide a formalin-fixed and paraffin-embedded (FFPE) tumor tissue specimen prior to treatment. The specimen may have been taken at any time during the course of the disease and may be from the primary tumor or from a metastasis
