NCT02577406

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

    The time between randomization and death from any cause. Participants who drop-out or are alive at the end of trial will have their OS times censored at the time of last contact, as appropriate.

    From randomization to death due to any cause (up to approximately 49 months)

Secondary Outcomes (19)

  • Overall Response Rate

    From randomization up to study completion (approximately 78 months)

  • Event-Free Survival

    From randomization up to study completion (approximately 78 months)

  • Duration of Response

    From randomization up to study completion (approximately 78 months)

  • Time to Response

    From randomization to to first documented MLFS/CR/CRi/CRp/PR (up to approximately 49 months)

  • Treatment Mortality at 30 Days

    From first dose to 30 days after first dose

  • +14 more secondary outcomes

Study Arms (2)

AG-221 plus Best supportive care (BSC)

EXPERIMENTAL

Continuous 28-day cycles of AG 221 100 mg orally (PO) once a day (QD) for 28 days, plus BSC.

Drug: AG-221Other: BSC

Conventional care regimen (CCR)

ACTIVE COMPARATOR

Continuous 28-day cycles of BSC only, azacitidine subcutaneously (SC) plus BSC, low-dose cytarabine (LDAC) SC plus BSC, or intermediate-dose cytarabine (IDAC) intravenously (IV) plus BSC.

Eligibility Criteria

Age60 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects must satisfy the following criteria to be enrolled in the study:
  • Subject is ≥ 60 years of age at the time of signing the ICF
  • Subject has primary (ie, de novo) or secondary (progression of MDS or myeloproliferative neoplasms (\[MPN\], or therapy-related) AML according to WHO classification (Appendix B)
  • Subject has received second- or third-line of AML therapy (see Appendix G for the definition of prior AML line; note that, for subjects having AML secondary to prior higher risk \[Intermediate-2 or High risk according to the International Prognostic Scoring System\] MDS treated with a hypomethylating agent \[eg, azacitidine or decitabine\], the hypomethylating therapy can be counted as a line if there is disease progression to AML during or shortly \[eg, within 60 days\] after the hypomethylating therapy.)
  • Subject has the following disease status:
  • Refractory to or relapsed after second- or third-line of intensive therapy for AML (eg, the "7 + 3" regimen):
  • at least 5% leukemic blasts in bone marrow (the minimum number of treatment cycles of the intensive therapy is per the investigator's discretion); or
  • Refractory to or relapsed after second- or third-line low-intensity AML therapy (eg, LDAC, azacitidine or decitabine):
  • at least 5% leukemic blasts in bone marrow after at least 2 treatment cycles
  • Subject is eligible for and willing to receive the pre-selected CCR treatment option, according to the investigator's assessment (Note: Subjects with degenerative and toxic encephalopathies, especially after the use of methotrexate or treatment with ionizing radiation, should not receive cytarabine.)
  • Subject has Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2 (Appendix D)
  • Subject has IDH2 gene mutations tested centrally (using the "investigational use only"PCR assay, Abbott RealTime IDH2) in samples of bone marrow aspirate and peripheral blood, and confirmed positive in bone marrow aspirate and/or peripheral blood. (Note: in the event that the central laboratory result is delayed and precludes acute clinical management of a subject who has confirmed IDH2 gene mutation by local evaluation, the subject may be eligible for randomization with approval by the Medical Monitor.)
  • Subject has adequate organ function defined as:
  • Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT) and alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT) ≤ 3 x upper limit of normal (ULN), unless considered due to leukemic organ involvement, following review by the Medical Monitor; and
  • Serum total bilirubin ≤ 1.5 x ULN, unless considered due to Gilbert's syndrome (eg, a gene mutation in UGT1A1) or leukemic organ involvement, following review by the Medical Monitor; and
  • +9 more criteria

You may not qualify if:

  • The presence of any of the following will exclude a subject from enrollment:
  • Subject is suspected or proven to have acute promyelocytic leukemia based on morphology, immunophenotype, molecular assay, or karyotype
  • Subject has AML secondary to chronic myelogenous leukemia
  • Subject has received a targeted agent against an IDH2 mutation
  • Subject has received systemic anticancer therapy or radiotherapy \< 14 days prior to the start of study treatment. Note that hydroxyurea is allowed prior to the start of study treatment for the control of leukocytosis (however, hydroxyurea should not be given within 72 hours prior to and after administration of azacitidine).
  • Subject has received non-cytotoxic or investigational agents \< 14 days or 5 half-lives, whichever is longer, prior to the start of study treatment
  • Subject has undergone HSCT within 60 days prior to the start of study treatment, or on immunosuppressive therapy post HSCT at the time of screening, or with clinically significant graft-versus-host disease (GVHD). The use of a stable dose of oral steroid post-HSCT and/or topical steroids for ongoing skin GVHD is permitted.
  • Subject has persistent, clinically significant non-hematologic toxicities from prior therapies
  • Subject has or is suspected of having central nervous system (CNS) leukemia. Evaluation of cerebrospinal fluid is only required if CNS involvement by leukemia is suspected during screening.
  • Subject has active uncontrolled systemic fungal, bacterial, or viral infection (defined as ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment)
  • Subject has immediately life-threatening, severe complications of leukemia such as uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation
  • Subject has significant active cardiac disease within 6 months prior to the start of study treatment, including New York Heart Association (NYHA) class III or IV congestive heart failure (Appendix E); acute coronary syndrome (ACS); and/or stroke; or left ventricular ejection fraction (LVEF) \< 40% by echocardiogram (ECHO) or multi-gated acquisition (MUGA) scan obtained within 28 days prior to the start of study treatment
  • Subject has prior history of malignancy, other than MDS, MPN or AML, unless the subject has been free of the disease for ≥ 1 year prior to the start of study treatment.
  • However, subjects with the following history/concurrent conditions are allowed:
  • Basal or squamous cell carcinoma of the skin
  • +15 more criteria
