An Efficacy and Safety Study of AG-221 (CC-90007) Versus Conventional Care Regimens in Older Subjects With Late Stage Acute Myeloid Leukemia Harboring an Isocitrate Dehydrogenase 2 Mutation (IDHENTIFY)

A Phase 3, Multicenter, Open-label, Randomized Study Comparing the Efficacy and Safety of AG-221 (CC-90007) Versus Conventional Care Regimens in Older Subjects With Late Stage Acute Myeloid Leukemia Harboring an Isocitrate Dehydrogenase 2 Mutation

This is an international, multicenter, open-label, randomized, Phase 3 study comparing the efficacy and safety of AG-221 versus conventional care regimens (CCRs) in subjects 60 years or older with acute myeloid leukemia (AML) refractory to or relapsed after second- or third-line AML therapy and positive for an isocitrate dehydrogenase (IDH2) mutation.

Study Overview

• Status: Active, not recruiting
• Conditions: Leukemia, Myeloid; Isocitrate Dehydrogenase
• Intervention / Treatment: Drug: AG-221; Other: BSC; Drug: Azacitidine; Drug: Low-dose cytarabine (LDAC); Drug: Intermediate-dose cytarabine (IDAC)

Detailed Description

Acute myeloid leukaemia (AML) is a form of cancer that is common in older patients. Mutations in the isocitrate dehydrogenase enzyme 2 (IDH2) have been found in approximately 15% of patients with AML.

The outcome of first line chemotherapy treatment is poor and many patients fail to attain complete remission (CR, ie refractory) or will eventually relapse. There is no single standard of care for relapsed or refractory AML. Since the prognosis is very poor there is a great need for new therapies.

Inhibition of the mutant IDH2 enzyme may represent a promising targeted therapy for AML. AG-221 is a small molecule inhibitor of the IDH2 enzyme, designed to preferentially target the mutant IDH2 variants. Data from the ongoing first-in-human study has shown AG-221 to be generally well tolerated and demonstrated CR in patients with IDH2 mutation positive relapsed or refractory AML.

The study purpose is to test the safety and efficacy of AG-221 compared with conventional care regimens (CCR), which include best supportive care (BSC) only, azacitidine plus BSC, low-dose cytarabine plus BSC or intermediate-dose cytarabine plus BSC, in patients with late stage AML refractory to or relapsed after second or third line therapy and positive for the IDH2 mutation. Patients will be randomly assigned to receive open-label tablets of AG-221 or one of the CCR on continuous 28-day treatment cycles. The trial duration is expected to be 78 months which includes 42 months enrollment, approximately 7 months treatment and a follow-up period.

Study procedures include: vital signs, physical exams, ECGs, ECHO, urine/blood samples, bone marrow aspirates and/or biopsies and peripheral blood to test for IDH2 and assess treatment response. Bone marrow, blood, cheek swab samples will be used for genetic tests.

This study is being sponsored by Celgene Corporation. Approximately 316 participants will take part in the study.

HI-E is defined as a hemoglobin increase by ≥ 1.5 g/dL and a relevant reduction in units of RBC transfusions by an absolute number of at least 4 RBC transfusions/8 week compared with the pretreatment transfusion number in the previous 8 week. HI-P is defined as an absolute increase of ≥ 30 X 10^9/L for participants starting with > 20 X and an increase from < 20 X 10^9/L to > 20 X 10^9/L and by at least 100%. HI-N is defined as At least 100% increase and an absolute increase > 0.5 X 10^9/L.	From randomization up to approximately 49 months
The Number of Participants That Underwent Hematopoietic Stem Cell Transplantation (HSCT)	The number of participants that underwent hematopoietic stem cell transplantation during the study.	From randomization up to approximately 49 months
Time to Treatment Failure	Time from randomization to discontinuation of study treatment due to any cause	From randomization to discontinuation of study treatment due to any cause (up to approximately 49 months)
The Number of Participants Experiencing Adverse Events (AEs)	The number of participants experiencing different types of adverse events (AE). An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participant during the course of a study. A Serious Adverse Event (SAE) is any AE occurring at any dose that: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or constitutes an important medical event. All AEs were coded using the MedDRA Version 22.0. Adverse events were analyzed in terms of treatment-emergent AEs (TEAEs). A treatment-related TEAE was defined as a TEAE that was suspected by the investigator to be related to study treatment. The severity was graded by the study personnel based on NCI National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03.	From first dose up to 28 days after last dose (up to approximately 49 months)
The Percent of Participants Experiencing Clinically Significant Laboratory Abnormalities - Serum Chemistry	The percent of participants with clinically significant serum chemistry laboratory abnormalities. A clinically significant laboratory abnormality is defined as meeting Grade 3 or Grade 4 criteria according to the Common Terminology Criteria for Adverse Events (CTCAE). Grade 3 is defined as severe or medically significant but not immediately life threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care. Grade 4 is defined as life-threatening consequences; urgent intervention indicated. The chemistry panel includes sodium, potassium, calcium, magnesium, chloride, phosphorus, CO2, bicarbonate, blood urea nitrogen (BUN), creatinine, glucose, albumin, total protein, alkaline phosphatase (ALP), bilirubin (total and direct), uric acid, lactate dehydrogenase (LDH), AST/SGOT, ALT/SGPT, gamma glutamyl transpeptidase (GGT), amylase and lipase.	From first dose up to approximately 49 months
The Percent of Participants Experiencing Clinically Significant Laboratory Abnormalities - Hematology	The percent of participants with clinically significant hematology laboratory abnormalities. A clinically significant laboratory abnormality is defined as meeting Grade 3 or Grade 4 criteria according to the Common Terminology Criteria for Adverse Events (CTCAE). Grade 3 is defined as severe or medically significant but not immediately life threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care. Grade 4 is defined as life-threatening consequences; urgent intervention indicated. The hematology panel includes complete blood count (CBC) with differential, including red blood cell (RBC) count, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), white blood cell (WBC) count (with differential), absolute neutrophil count (ANC) and platelet count.	From first dose up to approximately 49 months
The Percent of Participants Experiencing Clinically Significant Vital Sign Abnormalities	The percent of participants with clinically significant vital sign abnormalities including weight, temperature, blood pressure, pulse rate, and respiratory rate.	From first dose up to approximately 49 months
The Percentage of Participants Experiencing Clinically Significant Electrocardiogram (ECG) Abnormalities	The percent of participants with clinically significant ECG abnormalities. 12-lead ECG was assessed by a physician trained in ECG interpretation. Intervals including PR, QRS, QT and RR were collected, as well as heart rate and rhythm.	From first dose up to approximately 49 months
Change From Baseline in the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire (EORTC QLQ-C30)	The change from baseline in the EORTC QLQ-C30 questionnaire. The EORTC QLQ-C30 is composed of 30 items that address general physical symptoms, physical functioning, fatigue and malaise, and social and emotional functioning. Subscale scores are transformed to a 0 to 100 scale, with higher scores on functional scales indicating better function and higher scores on symptom scales indicating worse symptoms. A change of at least 10 points on the standardized domain scores was required for it to be considered meaningful. Results obtained just prior to the start of study treatment on Day 1 of Cycle 1 will serve as the baseline values. If not available, the most recent screening results prior to the start of study treatment on Day 1 of Cycle 1 will be considered the baseline values.	From baseline to cycle 2 day 1 (up to approximately 1 month)
Change From Baseline in EQ-5D-5L Health Utility Index	The European Quality of Life 5D-5L Scale (EQ-5D-5L) assesses general health-related quality of life. Health is defined in 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Responses are coded so that a '1' indicates no problem, and '5' indicates the most serious problem. The responses for the 5 dimensions are combined in a 5-digit number. These health states are converted to a single index value using the crosswalk method to the EQ-5D-3L value set from the United Kingdom (UK). The EQ-5D-3L health utility index based on the UK population weights range from -0.594 to 1.0 with higher scores indicating higher health utility. Baseline results are obtained just prior to the start of study treatment on Day 1 of Cycle 1 and will serve as the baseline values.	From baseline up to cycle 2 day 1 (up to approximately 1 month)
