DLT was any of the following drug related (DR) investigator-assessed adverse events: pancytopenia with hypocellular bone marrow and no marrow blasts lasting for ≥6 weeks; Grade (G)4 hematologic toxicity lasting ≥7 days except thrombocytopenia; G4 thrombocytopenia; G3 thrombocytopenia with bleeding; G3 or 4 febrile or infection-related neutropenia; G4 nonhematologic (NH) toxicity (not laboratory); G3 NH toxicity (not laboratory), nausea, vomiting, or diarrhea lasting >3 days despite supportive care; G3 or 4 NH laboratory abnormality requiring medical intervention, hospitalization, or persisting >1 week; increases in alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin, or international normalization ratio indicative of significant liver impairment; DR adverse event leading to discontinuation or ≥20% missed planned doses in Cycle 1; DR toxicity causing >2 week delay in starting Cycle 2; or G5 toxicity.

Secondary Outcome Measures

Percentage of Participants Who Experienced At Least One Adverse Event (AE)

An AE was defined as any untoward medical occurrence in a participant administered a study treatment and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the study treatment or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of study treatment, is also an AE. The percentage of all participants who experienced at least one AE is presented. Per protocol, these results are based on a data cutoff date of 09-May-2018.

Percentage of Participants Who Discontinued Study Treatment Due to an AE

An AE was defined as any untoward medical occurrence in a participant administered a study treatment and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the study treatment or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of study treatment, is also an AE. The percentage of all participants who discontinued study treatment due to an AE is presented. Per protocol, these results are based on a data cutoff date of 09-May-2018.

Objective Response Rate (ORR) in the Acute Myeloid Leukemia (AML) Cohort Per International Working Group Criteria: European LeukemiaNet (Döhner et al, Blood, 2010)

ORR was defined as the percentage of the participants who had complete response (CR) or partial response (PR) as assessed by investigator review. Participants in the AML cohort were assessed using bone marrow aspiration and hematologic criteria and response was evaluated based on European LeukemiaNet (Döhner et al, Blood, 2010). The criteria for complete response included: bone marrow blasts <5%; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count >1.0 × 10^9/Liter; platelet count >100 × 10^9/Liter; and independence of red cell transfusions. The criteria for partial response included: decrease of bone marrow blast percentage to 5% to 25%; decrease of pretreatment bone marrow blast percentage by at least 50%; and all hematologic criteria associated with CR. The percentage of participants who achieved CR or PR is presented.

Objective Response Rate (ORR) in the Diffuse Large B Cell Lymphoma (DLBCL) Cohort Per International Working Group Criteria: Lugano Classification (Cheson et al, Journal of Clinical Oncology, 2014)

ORR was defined as the percentage of the participants who had complete response (CR) or partial response (PR) as assessed by investigator review. Participants in the DLBCL cohort were assessed using computed tomography (CT) and positron emission tomography (PET)-CT and response was evaluated based on the Lugano Classification (Cheson et al, Journal of Clinical Oncology, 2014). The criteria for CR included complete metabolic (no/minimal fluorodeoxyglucose [FDG] uptake) and radiologic response (target lesions regress to ≤5 cm in longest transverse diameter of a lesion) and no new lesions. The criteria for PR included: partial metabolic (moderate/high FDG uptake) and radiologic response (≥50% decrease in sum of the product of the perpendicular diameters for multiple lesions of up to 6 target measurable nodes and extranodal sites, no increase in lesions, and spleen regressed by >50% in length beyond normal). The percentage of participants who achieved CR or PR is presented.

Duration of Response (DOR) in the Acute Myeloid Leukemia (AML) Cohort Per International Working Group Criteria: European LeukemiaNet (Döhner et al, Blood, 2010)

DOR was defined as the time from complete response (CR) or partial response (PR) to documented disease progression or death as assessed by investigator review. Participants in the AML cohort were assessed using bone marrow aspiration and hematologic criteria and response was evaluated based on European LeukemiaNet (Döhner et al, Blood, 2010). The criteria for complete response included: bone marrow blasts <5%; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count >1.0 × 10^9/Liter; platelet count >100 × 10^9/Liter; and independence of red cell transfusions. The criteria for partial response included: decrease of bone marrow blast percentage to 5% to 25%; decrease of pretreatment bone marrow blast percentage by at least 50%; and all hematologic criteria associated with CR.

Disease Control Rate (DCR) in the Acute Myeloid Leukemia (AML) Cohort Per International Working Group Criteria: European LeukemiaNet (Döhner et al, Blood, 2010)

DCR was defined as the percentage of the participants who had stable disease, complete response (CR) or partial response (PR) as assessed by investigator review. Participants in the AML cohort were assessed using bone marrow aspiration and hematologic criteria and response was evaluated based on European LeukemiaNet (Döhner et al, Blood, 2010). The criteria for complete response included: bone marrow blasts <5%; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count >1.0 × 10^9/Liter; platelet count >100 × 10^9/Liter; and independence of red cell transfusions.

Change From Baseline in Bromodomain and Extra-Terminal Domain (BET) Protein Target Gene Expression at 3 Hours Postdose on Day 1 of Cycle 1 (21-day Cycle)

Fold change from baseline (predose on Day 1 of Cycle 1 [21-day cycle]) in normalized gene expression ratios (nGER) for 49 target genes was measured to assess target engagement of BET proteins predose and 3 hours postdose using quantitative polymerase chain reaction (qPCR). Data were normalized by the delta-delta cycle threshold (Ct) method using housekeeping genes. Fold change from baseline was calculated as nGER at 3 hours postdose Day 1/baseline in logarithmic scale with a base of 2 (Log2 scale). Per protocol, target genes were assessed across all study participants by dose and this assessment was not related to any specific disease cohort. The fold change in nGER for each target gene is presented for participants pooled from the AML and DLBCL cohorts since both cohorts received the same dose. A two-fold increase in gene expression indicated a +1 Log2 fold change. Conversely, a two-fold decrease in gene expression indicated a -1 Log2 fold change.

Brief Summary

This is a study to determine the recommended dose of birabresib (MK-8628) for further studies in participants with acute myeloid leukemia (AML) including AML de novo and AML secondary to myelodysplastic syndrome (MDS) and in participants with diffuse large B cell lymphoma (DLBCL).
