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
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
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.
Phase II Study of Combined Tretinoin and Arsenic Trioxide for Patients With Newly Diagnosed Acute Promyelocytic Leukemia Followed by Risk-Adapted Postremission Therapy
Induction will consist of tretinoin 45 mg/m2 po daily (rounded up to the nearest 10mg) in two
divided doses (25 mg/m2 in patients <20 years of age) for 35 days and ATO 0.15 mg/kg IV daily
for 35 doses given 5-7 days per week. The drugs will then be discontinued, and the patient
will be followed until a clinical complete remission is achieved. Idarubicin 12 mg/m2 IV for
4 doses will be added during induction on day 2 if the presenting WBC is >10,000/μl, or if
the WBC increases to 5,000/μl on day 5, 10,000/μl on day 10, or 15,000/μl on day 15, because
of the increased risk of the APL differentiation syndrome and relapse in these patients.
Dexamethasone 10 mg twice daily with be given on days 1-14 of induction as prophylaxis for
the APL differentiation syndrome. All patients will then receive four courses of
consolidation with tretinoin 45 mg/m2 po daily (rounded up to the nearest 10mg) (25 mg/m2 in
patients <20 years of age) for 15 days and ATO 0.15 mg/kg IV for 25 doses.
Patients with high-risk disease or who received Idarubicin during Induction may receive
intrathecal cytarabine as CNS prophylaxis given by the treating physician during
consolidation, at the discretion of the site PI. High-risk patients will also receive
maintenance therapy with additional courses of tretinoin and ATO every 3 months for 2 years.
Each maintenance course will consist of tretinoin 45 mg/m2 po daily (25 mg/m2 in patients <20
years of age) for 15 days and ATO 0.15 mg/kg IV for 10 doses. Disease status will be
monitored with serial analyses of peripheral blood samples using RT-PCR for PML-RARα mRNA.
Patients will be followed until relapse, death, loss to follow-up, or removal from study.
Induction therapy can be given as an inpatient or outpatient. Consolidation and maintenance
treatments will be given as an outpatient. Consolidation may also be given at the patient's
local institution. Intrathecal cytarabine treatments will be administered as an outpatient.

A Pivotal Multicenter Trial of Moxetumomab Pasudotox in Relapsed/ Refractory Hairy Cell Leukemia
- Hairy cell leukemia is an indolent B-cell leukemia comprising 2% of all leukemias, or
approximately 900 of the 44,000 new cases of leukemia/year in the US
- Over the last two decades, immunotoxin research has accumulated to support a role for
CD22-targeted therapy in the treatment of HCL.
- Moxetumomab pasudotox is a recombinant immunotoxin containing an Fv fragment of an
anti-CD22 monoclonal antibody and truncated Pseudomonas exotoxin.
- Moxetumomab pasudotox has demonstrated a high complete response (CR) rate in patients
with chemoresistant hairy cell leukemia (HCL) and has shown activity in pediatric acute
lymphoblastic leukemia as well.
- Modification of the structure of moxetumomab pasudotox has greatly improved binding and
cytotoxicity toward CD22 expressing malignant cells compared to the precursor molecule.
Preclinical and clinical studies have demonstrated that this increase in binding
affinity results in improved antitumor activity and tolerability
- Currently there are no approved agents with significant efficacy for HCL patients after
failure of standard therapy
- This is a multicenter, single-arm study of moxetumomab pasudotox in patients with
relapsed/refractory hairy cell leukemia.
- 77 patients will be enrolled to receive moxetumomab pasudotox IV on days 1, 3 and 5 of
each 28 day cycle for a maximum of 6 cycles or until disease progression, unacceptable
toxicity occurs, the subject begins alternate therapy, or documented CR (for subjects
who have no assessable minimal residual disease and not to exceed 6 cycles). If less
than or equal to 2 of the first 25 patients do not achieve durable CR, no additional
patients will be accrued.
- The overall IRB accrual ceiling is currently set at 80 to allow for a small number of
patients that cannot be assessed for response.
