This study investigates the combined use of Ivosidenib, venetoclax, and azacitidine in patients with newly diagnosed acute myeloid leukemia (AML) that carries an IDH1 mutation. It enrolls patients aged 18 and older with an IDH1 R132 mutation who have not previously been treated for AML. It is in Phase 2 and is currently recruiting.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria:
1. Be ≥18 years of age
2. Have previously untreated AML, defined according to World Health Organization criteria. Subjects with extramedullary disease alone (ie, no detectable bone marrow and no detectable peripheral blood AML) are not eligible for the study.
3. Have an IDHl mutation resulting in an R132C, R132G, R132H, R132L, or R132S substitution.
4. Have an ECOG PS score of 0 to 2.
5. Have adequate hepatic function, as evidenced by:
* Serum total bilirubin ≤2 × ULN, unless considered to be due to Gilbert's disease or underlying leukemia, where it must be \<3 x ULN.
* Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤3.0 × ULN, unless considered to be due to underlying leukemia.
6. Have adequate renal function, as evidenced by serum creatinine ≤2.0 x ULN or creatinine clearance \>30 mL/min based on the Cockcroft-Gault glomerular filtration rate.
7. Have agreed to undergo serial blood and bone marrow sampling.
8. Be able to understand and willing to sign an informed consent form.
9. Be willing to complete QoL assessments during study treatment and at the designated time points following treatment discontinuation.
10. If female with reproductive potential, must have a negative serum pregnancy test prior to the start of study therapy. Female subjects with reproductive potential are defined as sexually mature women who have not undergone a hysterectomy, bilateral oophorectomy, or tubal occlusion or who have not been naturally postmenopausal for at least 24 consecutive months. Females of reproductive potential, as well as fertile men with female partners of reproductive potential, must use 2 effective forms of contraception (including at least 1 barrier form) from the time of giving informed consent throughout the study and for 90 days (both females and males) following the last dose of study drugs). Effective forms of contraception are defined as hormonal oral contraceptives, injectables, patches, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal ligation, condoms with spermicide, or male partner sterilization.
Exclusion Criteria:
1. Have received any prior treatment for AML with the exception of nononcolytic treatments to stabilize disease such as hydroxyurea or leukapheresis.
2. Have received a hypomethylating agent for myelodysplastic syndrome (MDS).
3. Subject has favorable risk cytogenetics such as t(8;21), inv(16), t(16;16) or t(15;17).
4. Subject has acute promyelocytic leukemia
5. Subjects who had previously received treatment for an antecedent hematologic disorder, including investigational agents, may not be randomized until a washout period of at least 5 half-lives of the investigational agent has elapsed since the last dose of that agent.
6. Have received prior treatment with an IDH1 inhibitor or BCL-2 inhibitor.
7. Have a known hypersensitivity to any of the components of Ivosidenib, venetoclax, or azacitidine.
8. Are female and pregnant or breastfeeding.
9. Are taking known strong cytochrome P450 (CYP) 3A4 inducers or sensitive CYP3А4 substrate medications with a narrow therapeutic window, unless they can be transferred to other medications within ≥5 half-lives prior to dosing.
10. Have an active, uncontrolled, systemic fungal, bacterial, or viral infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment.
11. Have a prior history of malignancy other than MDS or myeloproliferative disorder, 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 or similar indolent cancer are allowed to participate in the study:
* Basal or squamous cell carcinoma of the skin
* Carcinoma in situ of the cervix
12. Have had significant active cardiac disease within 6 months prior to the start of study treatment, including New York Heart Association Class (NYHA) Class III or IV congestive heart failure, myocardial infarction, unstable angina, and/or stroke.
13. Have a heart-rate corrected QT interval using Fridericia's method (QTcF) \>470 msec or any other factor that increases the risk of QT prolongation or arrhythmic events (eg, NYHA Class III or IV congestive heart failure, hypokalemia, family history of long QT interval syndrome). Subjects with prolonged QTcF interval in the setting of bundle branch block may participate in the study.
14. Have a known infection caused by human immunodeficiency virus or active hepatitis B virus (HBV) or hepatitis C virus that cannot be controlled by treatment.
15. Have dysphagia, short-gut syndrome, gastroparesis, or any other condition that limits the ingestion or gastrointestinal absorption of orally administered drugs.
16. Have uncontrolled hypertension (systolic blood pressure \[BP\] \>180 mmHg or diastolic BP\>100 mmHg).
17. Have clinical symptoms suggestive of active central nervous system (CNS) leukemia or known CNS leukemia. Evaluation of cerebrospinal fluid during Screening is only required if there is a clinical suspicion of CNS involvement by leukemia during Screening.
18. Have immediate, life-threatening, severe complications of leukemia, such as uncontrolled bleeding, pneumonia with hypoxia or sepsis, and/or disseminated intravascular coagulation.
19. Have any other medical or psychological condition deemed by the Investigator to be likely to interfere with the subject's ability to give informed consent or participate in the study.
20. Are taking medications that are known to prolong the QT interval unless they can be transferred to other medications within ≥5 half-lives prior to dosing, or unless the medications can be properly monitored during the study. (If equivalent medication is not available, heart rate corrected QT interval \[QTc\] will be closely monitored.)
21. Subjects with a known medical history of progressive multifocal leukoencephalopathy.
