Study of Orally Administered Enasidenib (AG-221) in Adults With Advanced Solid Tumors, Including Glioma, or Angioimmunoblastic T-cell Lymphoma, With an IDH2 Mutation

Completed · Phase 1/Phase 2

Conditions studied: Solid Tumor, Glioma, Angioimmunoblastic T-cell Lymphoma, Intrahepatic Cholangiocarcinoma, Chondrosarcoma

In brief

The purpose of this study is to evaluate the safety, pharmacokinetics, and clinical activity of enasidenib in adults with advanced solid tumors, including glioma, or with angioimmunoblastic T-cell lymphoma (AITL), with an isocitrate dehydrogenase-2 (IDH2) mutation.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subject must be ≥ 18 years of age
• Histologically or cytologically confirmed advanced solid tumor, including glioma, or angioimmunoblastic T-cell lymphoma (AITL) that has recurred or progressed following standard therapy, or that has not responded to standard therapy
• Subjects must be amenable to peripheral blood sampling, urine sampling, and biopsies during the study. Subjects with AITL must also be amenable to serial bone marrow biopsies
• Documented IDH2 gene-mutated disease based on local site testing
• Measurable disease by RECIST v1.1 for subjects with solid tumors without glioma, by modified RANO criteria for subjects with glioma, or by the revised IWG criteria for subjects with AITL
• Subjects must have Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
• Adequate bone marrow function (subjects other than those with AITL) as evidenced by: absolute neutrophil count ≥ 1.0 ×10\^9/L; hemoglobin > 9 g/dL (subjects may be transfused red blood cells to this level.); platelets ≥ 50 × 10\^9/L
• Adequate hepatic function as evidenced by: serum total bilirubin ≤ 1.5 × upper limit of normal (ULN), unless considered due to Gilbert's disease, a gene mutation in UGT1A1, or disease involvement, following approval by the Medical Monitor; aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) ≤ 2.5 × ULN, with the exception of subjects with bone metastases and/or suspected disease-related liver or biliary involvement, where ALP must be ≤ 5 × ULN
• Adequate renal function as evidenced by: serum creatinine ≤ 2.0 × ULN; OR creatinine clearance > 40 mL/min based on the Cockroft-Gault glomerular filtration rate (GFR) estimation: (140 - Age) x (weight in kg) x (0.85 if female)/72 x serum creatinine
• Female subjects with reproductive potential must have a negative serum pregnancy test within 7 days prior to the start of therapy. Women of childbearing potential as well as fertile men and their partners must agree to abstain from sexual intercourse or to use an effective form of contraception during the study and for 90 days (females and males) following the last dose of AG-221
• Previous allogeneic stem cell transplant is allowed only if subjects are >100 days from stem cell transplant and do not have uncontrolled acute or chronic graft-vs-host disease

You may not qualify if…

• Received systemic anticancer therapy or radiotherapy < 21 days prior to their first day of study drug administration
• Received an investigational agent < 14 days prior to their first day of study drug administration. In addition, the first dose of AG-221 should not occur before a period ≥ 5 half-lives of the investigational agent has elapsed
• Subjects taking the following sensitive cytochrome P450 (CYP) substrate medications that have a narrow therapeutic range are excluded from the study unless they can be transferred to other medications prior to enrolling: paclitaxel (CYP2C8), warfarin, phenytoin (CYP2C9), S-mephenytoin (CYP2C19), thioridazine (CYP2D6), theophylline and tizanidine (CYP1A2)
• Subjects taking the P-glycoprotein (P-gp) and breast cancer resistant protein (BCRP) transporter-sensitive substrates digoxin and rosuvastatin should be excluded from the study, unless they can be transferred to other medications prior to enrolling. study unless they can be transferred to other medications prior to enrolling
• Subjects for whom potentially curative anticancer therapy is available
• Pregnant or breastfeeding
• Active severe infection that required anti-infective therapy 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)
• Known hypersensitivity to any of the components of AG-221
• Subjects with New York Heart Association (NYHA) Class III or IV congestive heart failure or left ventricular ejection fraction (LVEF) < 40% by echocardiogram (ECHO) or multi-gated acquisition (MUGA) scan within approximately 28 days of Cycle 1Day 1
• History of myocardial infarction within the last 6 months
• Subjects with uncontrolled hypertension (systolic blood pressure > 180 mmHg or diastolic blood pressure > 100 mmHg) are excluded. Subjects requiring 2 or more medications to control hypertension are eligible with Medical Monitor approval.
• Known unstable or uncontrolled angina pectoris
• Known history of severe and/or uncontrolled ventricular arrhythmias
• Heart-rate corrected QT (QTc) interval > 450 msec or with other factors that increase the risk of QT prolongation or arrhythmic events (e.g., heart failure, hypokalemia, family history of long QT interval syndrome). Subjects with right bundle branch block and a prolonged QTc interval should be reviewed by the Medical Monitor for potential inclusion
• Subjects taking medications that are known to prolong the QT interval
• Known infection with human immunodeficiency virus (HIV) or active hepatitis B or C
• Any other medical or psychological condition, deemed by the Investigator to be likely to interfere with a subject's ability to sign informed consent, cooperate, or participate in the study
• Known dysphagia, short-gut syndrome, gastroparesis, or other conditions that limit the ingestion or gastrointestinal absorption of drugs administered orally
• Subjects with brain metastases that are untreated, symptomatic, or require therapy to control symptoms; or any radiation, surgery, or other therapy, including to control symptoms, within 2 months of first dose. Subjects with glioma who are on a stable, steroid-dosing regimen prior to screening magnetic resonance imaging (MRI) may be permitted to enroll with Medical Monitor approval
• In subjects with AITL, evidence of meningeal or cerebral disease or a history of progressive multifocal leukoencephalopathy
• Radiotherapy involving < 25% of the hematopoietically active bone marrow within 21 days preceding first dose of study treatment
• Radiotherapy involving ≥ 25% of the hematopoietically active bone marrow within 42 days preceding first dose of study treatment
