Study of Orally Administered AG-120 in Subjects With Advanced Hematologic Malignancies With an IDH1 Mutation
- Conditions
- Myelodysplastic SyndromesRelapsed or Refractory Acute Myeloid Leukemia (AML)Untreated AMLOther IDH1-mutated Positive Hematologic Malignancies
- Interventions
- Drug: AG-120
- Registration Number
- NCT02074839
- Lead Sponsor
- Institut de Recherches Internationales Servier
- Brief Summary
The purpose of this Phase I, multicenter study is to evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of AG-120 in advanced hematologic malignancies that harbor an IDH1 mutation. The first portion of the study is a dose escalation phase where cohorts of patients will receive ascending oral doses of AG-120 to determine maximum tolerated dose (MTD) and/or the recommended Phase II dose. The second portion of the study is a dose expansion phase where four cohorts of patients will receive AG-120 to further evaluate the safety, tolerability, and clinical activity of the recommended Phase II dose. Additionally, the study includes a substudy evaluating the safety and tolerability, clinical activity, pharmacokinetics, and pharmacodynamics of AG-120 in subjects with relapsed or refractory myelodysplastic syndrome with an IDH1 mutation. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

- Subjects must have adequate hepatic function as evidenced by: Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤3.0 × ULN, unless considered due to leukemic disease and serum total bilirubin ≤1.5 x upper limit of normal (ULN), unless considered due to Gilbert's disease or leukemic disease
- Subjects must have adequate renal function as evidenced by a serum creatinine ≤2.0 × ULN or creatinine clearance >40mL/min based on Cockroft-Gault glomerular filtration rate (GFR)
- Subjects must be recovered from any clinically relevant toxic effects of any prior surgery, radiotherapy, or other therapy intended for the treatment of cancer.
- Female subjects with reproductive potential must have a negative serum pregnancy test within 7 days prior to the start of therapy and on the first day of study drug administration.
Key
- Subjects who have undergone hematopoietic stem cell transplant (HSCT) within 60 days of the first dose of AG-120, or subjects 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 steroids post HSCT and/or topical for ongoing skin GVHD is permitted.)
- Subjects who received systemic anticancer therapy or radiotherapy <14 days prior to their first day of study drug administration. (Hydroxyurea is allowed prior to enrollment and after the start of AG-120).
- Subjects who received an investigational agent <14 days prior to their first day of study drug administration.
- Subjects who are pregnant or breastfeeding.
- Subjects with an active severe infection or with an unexplained fever >38.5°C during screening visits or on their first day of study drug administration (at the discretion of the Investigator, subjects with tumor fever may be enrolled).
- Subjects with New York Heart Association (NYHA) Class III or IV congestive heart failure or LVEF <40% by echocardiogram (ECHO) or multi-gated acquisition (MUGA) scan within approximately 28 days of C1D1.
- Subjects with a history of myocardial infarction within the last 6 months of screening.
- Subjects with a known unstable or uncontrolled angina pectoris.
- Subjects with a known history of severe and/or uncontrolled ventricular arrhythmias.
- Subjects with known unstable or uncontrolled angina pectoris.
- Subjects with heart-rate corrected QT (QTc) interval ≥450 ms or other factors that increase the risk of QT prolongation or arrhythmic events.
- Patients taking medications that are known to prolong the QT interval
- Subjects with known infection with human immunodeficiency virus (HIV) or active hepatitis B or C.
- Subjects with clinical symptoms suggesting active central nervous system (CNS) leukemia or known CNS leukemia. Evaluation of cerebrospinal fluid is only required if there is a clinical suspicion of CNS involvement by leukemia during screening.
- Subjects with immediately life-threatening, severe complications of leukemia such as uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation.

Group Intervention Description AG-120 AG-120 AG-120 administered continuously as a single agent dosed orally every day of a 28-day cycle.
- Primary Outcome Measures
Name Time Method Maximum Tolerated Dose and/or the recommended Phase II dose of AG-120 in subjects with advanced hematologic malignancies. up to 26 weeks, on average Assess clinical activity of AG-120 in subjects with relapsed or refractory AML who are enrolled in the Expansion Phase. up to 26 weeks, on average Safety/tolerability: incidence of adverse events. up to 26 weeks, on average Safety/tolerability of treatment with AG-120 in subjects with relapsed or refractory myelodysplastic syndrome. up to 26 weeks, on average Assess clinical activity of AG-120 in subjects with relapsed or refractory myelodysplastic syndrome. up to 26 weeks, on average
- Secondary Outcome Measures
Name Time Method Pharmacokinetics of AG-120 in subjects with advanced hematologic malignancies. up to 26 weeks, on average Descriptive statistics will be used to summarize PK parameters for each dose group and, where appropriate, for the entire population. Such parameters will include (but are not limited to) maximum concentration (Cmax), time to maximum concentration (Tmax), AUC, elimination half-life, and the fraction of drug excreted unchanged in the urine.
Serial blood sampling at specified time points for determination of plasma concentration-time profiles and PK parameters (Tmax) of AG-120 in subjects with R/R MDS. up to 26 weeks, on average Serial blood sampling at specified time points for determination of plasma concentration-time profiles and PK parameters (AUC) of AG-120 in subjects with R/R MDS. up to 26 weeks, on average Dose Limiting Toxicities of AG-120 in subjects with advanced hematologic malignancies. up to 26 weeks, on average Pharmacodynamic relationship of AG-120 and 2-HG. up to 26 weeks, on average The potential relationship between plasma exposure of AG-120 and plasma, urine, or bone marrow 2-HG levels will be explored with descriptive and graphical methods.
Clinical Activity of AG-120 in advanced hematologic malignancies according to the 2003 revised IWG criteria for AML or the 2006 modified IWG criteria for MDS or MDS/myeloproliferative neoplasms (MPN). up to 26 weeks, on average Serial blood sampling at specified time points for determination of plasma concentration-time profiles and PK parameters (Cmax) of AG-120 in subjects with R/R MDS. up to 26 weeks, on average Blood and bone marrow sampling at specified time points for determination of 2-HG levels to characterize the percent of 2-HG inhibition of AG-120 in plasma and bone marrow. up to 26 weeks, on average
