Study summary

This is an open-label, randomized, multicenter, phase III study

Patients with baseline Hb comprised between 9 and 10.5g/dl will be randomized to receive EPO Alfa 60000 UI/week for at least 12 weeks:

  • Either at diagnosis Or
  • at the Hb threshold chosen for RBC transfusions (must be \< 9g/dl)
Read the detailed description

in this trial we will compare the early introduction of EPO alfa to the delayed introduction in lower risk MDS with non RBC transfusion dependent anemia.

At enrollment patients will be randomised in the 2 arms (early and delayed start of EPO alfa).

Treatment Regimen Epoetin alfa 60000 UI/week for at least 12 weeks

  1. Early onset arm: early onset of EPO ALFA 60000 IU/week , at patient inclusion
  2. Delayed onset arm: late introduction of EPO ALFA 60000 IU/week, whenever the patient reaches the level chosen RBC transfusions (based on age, comorbidities, anticipated tolerance of anemia).

Inclusion criteria

  1. Age ≥ 18 years
  2. MDS according to WHO 2016 criteria, with low or int 1 classical IPSS
  3. Non-RBC transfusion dependent anemia
  4. level between 9 and 10.5g/dl (at the center's lab)
  5. Hb level should be at least 1g/dl higher than the Hb threshold chosen to start RBC transfusions based on age, comorbidities and predicted clinical tolerance of anemia (this transfusion threshold should be chosen between 8 and 9g/dl)
  6. Serum EPO level \<500U/l
  7. No other cause of anemia (including iron deficiency, vitamin B12 or B9 deficiency, hemolysis, hypothyroidism….)
  8. Performance status \<=2

Exclusion criteria

Exclusion Criteria:

  1. Higher risk MDS (IPSS intermediate-2 or high)
  2. Del 5q
  3. Baseline level > 10.5 g/dl or \<9g/dl
  4. Transfusion threshold (based on age , comorbidities…) >9g/dl
  5. Transfusion threshold less than 1 g/dl below baseline Hb level
  6. RBC transfusion dependence. Patients may have received only one transfusion series for MDS prior to inclusion
  7. CMML , if >10 % BM blasts or WBC>13.000/mm3
  8. Uncontrolled hypertension
  9. Uncontrolled cardiovascular disease including angina pectoris or cardiac failure
  10. Renal failure: \<40ml/min (using formula)
  11. Pregnancy (positive bettaHCG) or nursing
Terms in these criteria, in plain language(3)

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.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

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.

What researchers measure

Primary outcomes

  1. Time to RBC transfusion dependence in non RBC transfusion dependent lower risk MDS patients with anemia with early (at inclusion of the patient) versus delayed onset,( at the threshold chosen for RBC transfusion) of EPO ALFA

    RBC transfusion dependence will be defined by requirement of at least transfusions of 2 PRBC within an interval of less than 8 weeks, given for Hb \<8g/dl or \<9g/dl according to comorbidities and in the absence of other cause of anemia (bleeding, surgery…), taking into account only transfusions given at least 12 weeks after onset of treatment with EPO ALFA.

    Time frame: 12 weeks

Secondary outcomes

  1. Erythroid response (according to IWG 2006 criteria)

    Erythroid response (according to IWG 2006 criteria) after 12 weeks of EPO ALFA treatment

    Time frame: 12 weeks

  2. response duration to EPO ALFA

    response duration to EPO ALFA measured from the date of enrollment until failure

    Time frame: 4 years

  3. Overall survival

    Overall survival measured from the date of enrollment to death or the date of last contact

    Time frame: 4 years

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

Ran from Mar 2018 to primary completion in Sep 2023, 65 months.

Of 45 phase 3 interventional studies under Myelodysplastic Syndromes, half reached primary completion within 50 months of starting (the median), counting those still running; a quarter within 38 and three quarters within 95. This study's 65 months is above that.

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 Sep 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
