Study summary

To explore the efficacy and safety of prolonged low-dose decitabine (10 days of 6mg/m2) plus venetoclax (3 weeks/cycle) regimen in primary diagnosed elderly or frail AML/ high-risk MDS.

Read the detailed description

Acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) are hematological malignancies. Some patients are over 65 years old, have poor response to traditional chemotherapy, and rarely have the opportunity to receive allogeneic hematopoietic stem cell transplantation, resulting in poor prognosis and short survival.

In recent years, with the advent of molecular targeted drugs Bcl-2 inhibitors, the treatment of elderly AML/ high-risk MDS has achieved breakthrough progress. In particular, the combination of demethylated drugs (decitabine/azacidacidin) and Bcl-2 inhibitors of chemotherapy-free regimen has been recommended by NCCN as the first-line treatment for elderly and frail patients.

However, how to achieve the optimal combination of decitabine and Bcl-2 inhibitors is an urgent problem to be solved.

Our previous pilot trial showed that prolonged low-dose decitabine combined with venetoclax (Bcl-2 inhibitor) resulted in higher complete remission rate, longer disease-free survival, and lower treatment-related risks.

The purpose of this study was to expand the multi-center sample to explore the efficacy and safety of prolonged low-dose decitabine plus venetoclax regimen in primary diagnosed elderly or frail AML/ high-risk MDS.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Patients must be diagnosed with acute myeloid leukemia (non-acute promyelocytic leukemia)/high-risk myelodysplastic syndrome before admission.

    Diagnostic criteria refer to 2016 WHO classification.

  2. Age 60 or older.
  3. The scores of physical fitness in the Eastern Tumor Cooperative group () ranged from 0 to 3(see Appendix 1).
  4. ≥30 mL/min(as assessed by the Cockcrod-Gault formula [Cockcroft et al 1976] [13] or the estimated [eGFR] from the Kidney Drink adjustment formula .
  5. (AST) and alanine aminotransferase (ALT)≤3× (ULN), total ≤2×ULN.
  6. Echocardiography (ECHO) showed (LVEF)≥50% (AHA 2016).
  7. >8 weeks.
  8. Sign the voluntarily, and understand and comply with the requirements of the study.

Exclusion criteria

Exclusion Criteria:

  1. Age \<60 years old.
  2. Treated patients who had received various chemotherapy regiments.
  3. Present active cardiovascular disease, such as uncontrolled arrhythmia, uncontrolled hypertension, congestive heart failure, any grade 3 or 4 heart disease as determined by the (NYHA) functional scale (see Appendix 2), or history of myocardial infarction in the 6 months prior to screening.
  4. Other serious diseases that may limit participation in the trial (e.g. advanced infections, uncontrolled diabetes).
  5. Those who cannot understand and follow the research plan or sign the .
Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2023 (actual). Primary completion is estimated for Oct 2025, 24 months after the start.

Of 386 non-industry phase 2 interventional studies under Leukemia, Myeloid, Acute, half reached primary completion within 67 months of starting (the median), counting those still running; a quarter within 40 and three quarters within 108. This study's planned 24 months is below that.

Counting every sponsor, half of 443 studies reached it within 60 months; a quarter within 38 and three quarters within 104.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 5, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
