Study of Biomarker-Based Treatment of Acute Myeloid Leukemia

Open to people ages 18 years and up

(IC):

• Adults, age ≥60 yrs at diagnosis unless in a specific known cytogenetic & genomic group for which treatment in Group A, B, or C is allowed by the substudy where age 18+ is allowed. Patients <60 yrs who are screened but do not fall w/in the cytogenetic & genomic open substudies would still be followed on the M1 Master Protocol (MP) & not considered screen fails
• Patients must be able to understand & provide written informed consent
• Group A: Patients must have previously untreated AML according to WHO classification w/ no prior treatment other than hydroxyurea. Patients w/ myeloid malignancies [eg, myelodysplastic syndrome (MDS) or other disease], will be allowed to enroll to this group. For previously untreated subjects w/ ≥20% blasts in bone marrow or blood only: Prior therapy for MDS, myeloproliferative syndromes (MPD), or aplastic anemia is permitted. For select group, patients who cannot wait or choose not to wait for results of genomic testing, will be allowed to enroll to select substudies that allow enrollment & treatment of all patients regardless of their genomic mutations or cytogenetics. For this group, genomic samples will be collected to be analyzed retrospectively after patients' enrollment
• Group B: Patients must have relapsed or refractory AML according to WHO classification. For study purposes, refractory AML is defined as failure to ever achieve a complete response (CR) or recurrence of AML w/in 6 months of achieving CR; relapsed AML is defined as all others w/ disease after prior remission. For select genomic aberrations specified in substudies, patients ≥18 yrs may be allowed to enroll in this portion of the study. Patients w/ relapsed or refractory myeloid malignancies (eg, MDS or other diseases) will be allowed to enroll to this group
• Group C: For select sites not part of Beat AML core sites. These sites will only participate in select substudies. Patients in this group will enroll under the Beat AML M1 MP w/ the intent to enroll into these select substudies & following screening on Beat M1 MP, they will come off M1 MP

(EC):

• Acute promyelocytic leukemia (APL)
• Clinically active CNS involvement by AML. A patient may be considered eligible if CNS leukemia is showing response to treatment at study entry & should continue to receive intrathecal therapy as clinical indicated. Patients who require or are undergoing craniospinal irradiation of disease control are not eligible for participation
• Signs of leukostasis requiring urgent therapy
• Disseminated intravascular coagulopathy (DIC) w/ active bleeding or signs of thrombosis
• Patients w/ psychological, familial, social, or geographic factors that otherwise preclude them from giving informed consent, following the protocol (including failure to collect genomics samples for screening), or complying w/ study treatment & follow-up
• Any other significant medical condition, including psychiatric illness or lab abnormality, that would preclude patient participation in the trial or would confound interpretation of trial results
