E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the Phase 1 portion of the study is to determine the Maximal Tolerated Dose (MTD) of ABT-199 in combination with low-dose cytarabine (LDC) in treatment-naïve subjects with Acute Myelogenous Leukemia (AML) who are ≥ 65 years of age and who are not eligible for standard Anthracycline-Based induction therapy due to co-morbidity or other factors.
The primary objective of the Phase 2 portion of the study is to evaluate the leukemia response rate and duration and characterize the toxicities of the combination at the Recommended Phase 2 Dose (RPTD). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate rate and duration of hematological response, including transfusion support needs and Progression-Free survival. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Subject must be ≥ 65 years of age.
2. Subject must have a projected life expectancy of at least 12 weeks.
3. Subject must have histological confirmation of AML and be ineligible for treatment with a standard cytarabine and anthracycline induction regimen due to co-morbidity or other factors.
4. Subject must have received no prior treatment for AML with the exception of hydroxyurea, allowed through first cycle of treatment. NOTE: Subject may have been treated for prior Myelodysplastic Syndrome.
5. Subject must have an Eastern Cooperative Oncology Group (ECOG) Performance status of 0 to 2.
6. Subject must have adequate renal function as demonstrated by a calculated creatinine clearance ≥ 50 mL/min; determined via urine collection for 24-hour creatinine clearance or by the Cockcroft Gault formula.
7. Subject must have adequate liver function as demonstrated by: aspartate aminotransferase (AST) ≤ 2.5 × ULN*, alanine aminotransferase (ALT) ≤ 2.5 × ULN*, bilirubin ≤ 1.5 × ULN*, Unless considered due to leukemic organ involvement.
Note: Subjects with Gilbert's Syndrome may have a bilirubin > 1.5 × ULN per discussion between the investigator and AbbVie medical monitor. |
|
E.4 | Principal exclusion criteria |
1. Subject has received treatment with cytarabine for a pre-existing myeloid disorder.
2. Subject has acute promyelocytic leukemia .
3. Subject has known active CNS involvement with AML.
4. Subject has tested positive for HIV (due to potential drug-drug interactions between antiretroviral medications and ABT-199, as well as anticipated ABT-199 mechanism-based lymphopenia that may potentially increase the risk of opportunistic infections). Note: HIV testing is not required.
5. Subject has received the following within 7 days prior to the initiation of study treatment:
• Potent CYP3A inducers such as rifampin, carbamazepine, phenytoin, and St. John's Wort;
• Warfarin or requires the use of warfarin (due to potential drug-drug interactions that may potentially increase the exposure of warfarin and complications of this effect).
6. Subject has received the following within 5 days prior to the initiation of study treatment:
• CYP3A inhibitors such as fluconazole, ketoconazole, and clarithromycin.
7. Subject has consumed grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges) or Starfruit within 3 days prior to the initiation of study treatment.
8. Subject has a cardiovascular disability status of New York Heart Association Class ≥ 2. Class 2 is defined as cardiac disease in which subjects are comfortable at rest but ordinary physical activity results in fatigue, palpitations, dyspnea, or anginal pain.
9. Subject has a white blood cell count > 25 × 109/L. Note: Hydroxyurea is permitted to meet this criterion. |
