A Survival Study in Patients With High Risk Myelodysplastic Syndromes Comparing Azacitidine Versus Conventional Care

16. října 2019 aktualizováno: Celgene

A Multicenter, Randomized, Open-label, Parallel-group, Phase 3 Trial of Subcutaneous Azacitidine Plus Best Supportive Care Versus Conventional Care Regimens Plus Best Supportive Care for the Treatment of Myelodysplastic Syndromes (MDS)

The purpose of this study is to determine whether patients with high-risk myelodysplastic syndromes (MDS) treated with azacitidine have improved survival compared to conventional care treatments. The study will also assess the effect of treatments on response, duration of response, and transformation to acute myeloid leukemia (AML). The study will continue for 12 months following last patient enrolled.

See study AZA PH GL 2003 CL 001 E for information about the extension to this study.

Detailní popis

Comparison/Control Interventions offered the physician three options:

  • Best supportive care (BSC) alone,
  • Low-dose cytarabine subcutaneously for 14 days every 28 to 42 days, or
  • Standard chemotherapy administered for induction as a continuous intravenous infusion of cytarabine over 7 days plus an anthracycline (daunorubicin, idarubicin, or mitoxantrone) on Days 1, 2, and 3; and, for those eligible, 1 or 2 consolidation cycles administered as continuous intravenous infusions of cytarabine for 3 to 7 days with the same anthracycline that was used at induction on Days 1 and 2 (each cycle between 28 to 70 days from the start of the previous cycle).

All three options included best supportive care. Neither the experimental group (azacitidine) nor any of the comparison/control options allowed use of erythropoietin.

Duration of Intervention: Patients will be treated until death, withdrawal, unacceptable toxicity or conclusion of the study.

Kaplan-Meier Estimates for Median Time to Death From Any Cause
Časové okno: Day 1 (randomization) to 42 months
Kaplan-Meier estimates for the median months until death from any cause within the intent-to-treat population. Patients surviving at the end of the follow-up period were censored at the date of last contact. If a patient withdrew consent to follow-up or was lost to follow-up, the patient was censored as of the last date of contact.

Kaplan-Meier estimates for the median months until death from any cause within the intent-to-treat population. Patients surviving at the end of the follow-up period were censored at the date of last contact. If a patient withdrew consent to follow-up or was lost to follow-up, the patient was censored as of the last date of contact.

Časové okno: Day 1 (randomization) to 42 months
The time to transformation to AML or death from any cause (whichever occurred first) was defined as the number of days from the date of randomization until the date of documented AML transformation or death from any cause. Patients who did not transform to AML or die were censored at the date of last follow-up.

Časové okno: Day 1 (randomization) to 42 months
The time to transformation to AML was defined as the number of days from the date of randomization until the date of documented AML transformation, defined as a bone marrow blast count ≥ 30% independent of baseline bone marrow count. Patients who did not transform to AML were censored at the date of last follow-up or date of death.
