NCT06014489

Brief Summary

The treatment of older unfit patients with acute myeloid leukemia (AML) is challenging. The hypomethylating agents (HMA) azacitidine and decitabine have relatively mild side effects and have proven to be feasible for the treatment of older patients and patients with co-morbidities. Currently, venetoclax added to an HMA agent is the new standard of treatment. Since this new standard comes with a substantial societal financial burden, there is a rational to optimize the venetoclax dosing schedule. The CYP3A4 inhibitor cobicistat (COBI) can be used to increase venetoclax exposure, thereby allowing to reduce the dose of venetoclax and thus costs substantially.

Study Arms (1)

single arm arm extension phase

EXPERIMENTAL

prior to the extention phase, there is a run-in phase with (n= 20 patients of 142 total) with the same study scheme, except that cobicistat is added from cycle 2 onwards to the treatment instead of during cycle 1

Drug: azacitidineDrug: VenetoclaxDrug: Cobicistat

Interventions

during run-in and extention phase: from Cycle 1 until relapse

single arm arm extension phase

during run-in and extention phase: from Cycle 1 until relapse

Eligibility Criteria

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

You may qualify if:

  • In order to be eligible to participate in this study, a patient must meet all of the following criteria:
  • Patients with: a diagnosis of AML and related precursor neoplasms according to ICC-2022 classification (excluding acute promyelocytic leukaemia) (appendix A). Patients may have had previous treatment with erythropoiesis stimulating agents (ESA) for an antecedent phase of MDS. ESAs must be stopped at least two weeks before registration.
  • Patients 18 years and older who are considered not fit for intensive chemotherapy or who decline the option of intensive chemotherapy.
  • WHO performance status 0, 1 or 2 (appendix E).
  • Adequate renal and hepatic functions unless clearly disease related as indicated by the following laboratory values:
  • Adequate renal function as demonstrated by a creatinine clearance ≥ 30 mL/min; calculated by the Cockcroft Gault formula or measured by 24 hours urine collection.
  • Serum bilirubin ≤ 3 x upper limit of normal (ULN), unless considered AML-related or due to Gilbert's syndrome.
  • Alanine transaminase (ALT) ≤ 3 x ULN, unless considered AML-related.
  • Male subjects who are sexually active, must agree, from Study Day 1 until at least 90 days after the last dose of study drug, to practice the protocol specified contraception. Male subjects must agree to refrain from sperm donation from initial study drug administration through at least 90 days after the last dose of study drug.
  • Female subjects must be either postmenopausal defined as: Age \>55 years with no menses for ≥12 months, without an alternative medical cause. OR willing and able to use adequate contraception during and until 180 days after the last protocol treatment.
  • Written informed consent.
  • Patient is capable of giving informed consent.
  • Patient agrees not to participate in another interventional study while on treatment without approval of the (co-) Principal Investigator.

You may not qualify if:

  • A patient who meets any of the following criteria cannot be included in this study:
  • Acute promyelocytic leukemia.
  • Myelodysplastic syndrome (MDS).
  • Patients previously treated for AML or MDS (any anti-leukemic therapy including investigational agents; excluding: 1) erythropoiesis stimulating agents (ESAs); 2) hydroxyurea (hydroxyurea is allowed for the control of peripheral leukemic blasts in patients with leukocytosis).
  • except when the patient successfully completed treatment (chemotherapy and/or surgery and/or radiotherapy) with curative intent for this malignancy at least 24 months prior to registration;
  • except for basal and squamous cell carcinoma of the skin or in situ carcinoma of the cervix.
  • Blast crisis of chronic myeloid leukemia.
  • Concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes, infection, hypertension, pulmonary disease etc.).
  • Cardiac dysfunction as defined by:
  • Myocardial infarction within the last 3 months of study entry, or
  • Reduced left ventricular function with an ejection fraction \< 40% as measured by MUGA scan or echocardiogram, or
  • Unstable angina or New York Heart Association (NYHA) grade IV congestive heart failure (see Appendix G), or
  • Unstable cardiac arrhythmias.
  • History of stroke or intracranial haemorrhage within 6 months prior to registration.
  • Symptomatic central nervous system (CNS) leukemia (NO routinely lumbar puncture required to investigate CNS involvement).
  • +6 more criteria
