Clinical Trial Summary

The primary objective is to determine the safety, tolerability, pharmacokinetics, maximum tolerated dose (MTD), or pharmacological active dose (PAD) of BAY2402234 in patients with acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or chronic myelomonocytic leukemia (CMML).

The secondary objective is to evaluate evidence of clinical efficacy associated with BAY2402234 in patients with AML (defined as Complete remission, Complete remission with partial hematologic recovery), and MDS (defined as hematological improvement).

Recruitment information / eligibility

• Enrollment: 40
• Est. completion date: January 26, 2021
• Est. primary completion date: January 26, 2021
• Accepts healthy volunteers: No
• Gender: All

Eligibility

Inclusion Criteria:

• Patients with relapsed or refractory AML. Relapsed AML is defined as relapse after achieving a response to initial therapy and refractory AML is defined as failure to achieve a response after one previous line of therapy. Response is defined as per IWG criteria (CR, CRi or CRp). Patients who are not candidates to receive or who decline standard of care therapy are also eligible.

• Patients with intermediate-1 or higher risk MDS who have failed therapy with a hypomethylating agent, or have failed lenalidomide therapy if harboring a 5q-chromosomal deletion.

• Patients with relapsed/refractory CMML.

• Estimated glomerular filtration rate (eGFR) > 40 mL per 1.73 m^2

• Patients must have adequate coagulation (international normalized ratio [INR] = 1.5; activated partial thromboplastin time [aPTT] =1.5 X the upper limit of normal [ULN]; patients on chronic anticoagulation therapy at investigator's discretion; patients on chronic use of direct-acting oral anticoagulants who have acceptable benefit-risk ratio at investigator's discretion)

• Adequate liver function (total bilirubin =1.5 X ULN (or =3 X ULN in patients with documented Gilbert's syndrome or for patients with hyperbilirubinemia considered due to myeloid disease), alanine aminotransferase [ALT] and aspartate aminotransferase [AST] =3 X ULN (or =5 X ULN for patients with liver involvement of their myeloid disease)

Exclusion Criteria:

• Patients eligible for hematopoietic stem cell transplantation

• Clinical symptoms suggesting active central nervous system (CNS) leukemia or known CNS leukemia

• Human immunodeficiency virus (HIV) infection

• Chronic or active hepatitis B or C if not controlled by antiviral therapy

• History of organ allograft (allogeneic bone marrow or stem cell transplant) within 3 months prior to first dose of study drug

• Serious, uncontrolled infection requiring systemic antibiotic, antifungal or antiviral therapy. Prophylactic antibiotic, antifungal and/or antiviral therapy is permitted

• Left ventricular ejection fraction (LVEF) <40%

Intervention

Drug:
• BAY2402234
BAY2402234 is a potent and selective small molecule inhibitor of dihydroorotate dehydrogenase. A solution of BAY2402234 will be available to initiate the trial and there are plans to transition to a tablet form of BAY2402234 once it becomes available. Both liquid and tablet formulations of BAY2402234 will be continually administered once daily by mouth in 28 day cycles.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum tolerated dose (MTD)	The MTD was defined as the maximum dose administered during Cycle 1 at which the estimated dose-limiting toxicity (DLT) probability is closest to 30%.	Up to 42 days after the first dose
Primary	Number of subjects with DLTs	A dose-limiting toxicity (DLT) was defined as any of the events that are clearly unrelated to underlying disease and occurring at any particular dose level during the first 28 days (i.e. Cycle 1) of treatment for non-hematological DLTs, or 42 days after the start of treatment, in the absence of active disease (i.e. < 5% blasts in bone marrow and absence of leukemic blasts in peripheral blood) for hematological DLTs. The National Cancer Institute Common Terminology Criteria for Adverse Events Version (CTCAE) v4.03 will be used to assess toxicities.	Up to 42 days after the first dose
Primary	AUC(0-24) (area under the concentration versus time curve from time zero to 24 hours) after single dose on Cycle 1 Day 1 (C1D1)		Pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24 hours after dose administration at C1D1
Primary	Cmax (maximum observed drug concentration in plasma after single dose administration) on C1D1		Pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24 hours (QD cohorts=until 24 hours; BID cohort=until 12 hours) after dose administration at C1D1
Primary	AUC(0-24)md (AUC(0-24) after multiple dose) on Cycle 1 Day 15 (C1D15)		Pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24 hours after dose administration at C1D15
Primary	Cmax,md (Cmax after multiple dose) on C1D15		Pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24 hours (QD cohorts=until 24 hours; BID cohort=until 12 hours) after dose administration at C1D1
Primary	Number of subjects with Treatment Emergent Adverse Events (TEAEs)	An AE was any untoward medical occurrence (i.e. any unfavorable and unintended sign [including abnormal laboratory findings], symptom or disease) in a patient or clinical investigation subject after providing written informed consent for participation in the study.	From first application of study intervention up to 30 days after end of treatment
Secondary	Number of acute myeloid leukemia (AML) patients with complete remission (CR) and complete response with partial recovery of peripheral blood counts (CRh)		Up to 6 months on average
Secondary	Number of myelodysplastic syndrome (MDS) patients with hematologic improvement (erythroid response, platelet response, and neutrophil response)		Every month until disease progression or patient was withdrawn from study, up to 6 months on average
