NCT07075016

Brief Summary

The standard treatment for patients with acute myeloid leukemia (AML) with an abnormality in the IDH1 gene, who are not eligible for intensive chemotherapy, is a combination of ivosidenib and azacitidine. In this study it is investigated whether adding venetoclax to the standard treatment can improve the outcome of the treatment of this specific form of AML. The safety is investigated and how well it works. In order to properly assess the value of venetoclax, the effect of venetoclax is compared with the effect of a placebo. A placebo is a product without an active ingredient, a 'fake medicinal product'.

Outcome Measures

Primary Outcomes (1)

  • Event-free survival (EFS) in patients with newly diagnosed IDH1-mutated AML ineligible for intensive chemotherapy

    Event-free survival (EFS) in patients with newly diagnosed IDH1-mutated AML ineligible for intensive chemotherapy, measured from the date of randomization to the date of treatment failure, hematologic relapse from CR/CRh or death from any cause, whichever occurs first. Treatment failure is defined as lack of obtaining either CR or CRh by week 24. Patients evaluable for response but not achieving CR or CRh by week 24 will be considered a treatment failure at day 1 post randomization to avoid ambiguities of variable or prolonged periods without response. Patients who die before week 24 without response assessments will also be considered treatment failures at day 1 post randomization. Patients who are alive but not evaluable for response will be censored at day 1 post randomization. Patients who achieved CR or CRh by week 24 and are not known to have morphologic relapse or died will be censored at the date of the last clinical assessment.

    12 months after inclusion of last AML patient

Secondary Outcomes (8)

  • Overall survival (OS) in patients with newly diagnosed IDH1-mutated AML

    12 months after inclusion of last AML patient

  • Rate of CR/CRh in patients with newly diagnosed IDH1-mutated AML

    12 months after inclusion of last AML patient

  • Rate of CR in patients with newly diagnosed IDH1-mutated AML

    12 months after inclusion of last AML patient

  • Rate of CR/CRi in patients with newly diagnosed IDH1-mutated AML

    12 months after inclusion of last AML patient

  • Rates of CR, CR/CRh and CR/CRi without measurable residual disease as assessed by multicolor flow cytometry

    12 months after inclusion of last AML patient

  • +3 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Central confirmation of IDH1 mutation in one of the dedicated central genetic laboratories.
  • Age ≥ 18 years, no upper age limit.
  • Patient is ineligible for intensive induction chemotherapy by meeting at least 1 of the following criteria:
  • older than or equal to 75 years of age ineligible for intensive chemotherapy per physician's discretion (with an ECOG performance status 0-2; Appendix C).
  • years: patient is not eligible for standard chemotherapy because of any of the following co-morbidities: o ECOG performance status 2 or 3 (Appendix C). o Cardiac history of chronic heart failure requiring treatment; or with an ejection fraction ≤50%; or chronic stable angina.
  • DLCO ≤ 65% or FEV1 ≤ 65%.
  • Creatinine clearance ≥ 30 mL/min to \<45 ml/min calculated by the Cockcroft Gault formula.
  • Moderate hepatic impairment with total bilirubin \> 1.5 to \< 3.0 x upper limit of normal (ULN).
  • Any other comorbidity that the local physician assesses to be incompatible with intensive chemotherapy. If a patient meets this criterion, sponsor must be informed via HO173@erasmusmc.nl
  • Patient must have a projected life expectancy of at least 12 weeks (as assessed by the treating physician).
  • Patient must have a white cell blood (WBC) count of \< 25 x 109/L. Hydroxyurea can be used prior to study enrollment to reduce the WBC count to meet this criterion.
  • Adequate renal function as evidenced by serum creatinine ≤ 2.0 × upper limit of normal (ULN) or creatinine clearance \>30 mL/min based on the Cockcroft-Gault glomerular filtration rate (GFR).
  • Adequate hepatic function as evidenced by:
  • Serum total bilirubin ≤ 3.0 × ULN unless considered due to Gilbert's disease, or leukemic involvement. If a patient meets this criterion, sponsor must be informed via HO173@erasmusmc.nl Page 30 of 117 HOVON 173 AML / AMLSG 34-23 / ACT-HOV-AML-001 Version 1.1, UK 11 FEB 2025
  • Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤ 3.0 × ULN, unless considered due to leukemic involvement. If a patient meets this criterion, sponsor must be informed via HO173@erasmusmc.nl
  • +10 more criteria

You may not qualify if:

  • Subject has previously been treated for AML; a treatment period with hydroxyurea to control WBC counts is allowed; prior treatment with a hypomethylating agent for MDS-EB is not allowed; prior treatment with erythropoiesis-stimulating agents or luspatercept for MDS is allowed.
  • Acute promyelocytic leukemia (APL) with t(15;17)(q24.1;q21.2); PML-RARA; or one of the other pathognomonic variant chromosomal translocations / fusion genes.
  • AML with BCR-ABL1; or myeloid blast crisis of CML
  • Significant active cardiac disease within 3 months prior to the start of study treatment, including:
  • \- New York Heart Association (NYHA) class III or IV congestive heart failure (Appendix F)
  • \- Myocardial infarction
  • \- Unstable angina
  • Severe cardiac arrhythmias
  • Congenital long QT syndrome of family member with this condition
  • QTcF \>480 msec on screening electrogram (mean of triplicate recordings).
  • Familial history of sudden death or polymorphic ventricular arrhythmia.
  • Severe obstructive or restrictive ventilation disorder.
  • History of stroke or intracranial hemorrhage within 6 months prior to randomization.
  • Clinical symptoms suggestive of active central nervous system (CNS) leukemia or known CNS leukemia. Evaluation of cerebrospinal fluid (CSF) during screening is only required if there is a clinical suspicion of CNS involvement by leukemia during screening.
  • Immediate life-threatening, severe complications of leukemia such as uncontrolled bleeding and/or disseminated intravascular coagulation.
  • +11 more criteria
