Warnings and Precautions Adverse Reactions Discontinuations and Dose Modifications

Warnings and Precautions

Risks of substitution with other azacitidine products1

  • Due to substantial differences in the pharmacokinetic parameters, the recommended dose and schedule for ONUREG® are different from those for the intravenous or subcutaneous azacitidine products
  • Treatment of patients using intravenous or subcutaneous azacitidine at the recommended dosage of ONUREG® may result in a fatal adverse reaction
  • Treatment of patients using ONUREG® at the doses recommended for intravenous or subcutaneous azacitidine may not be effective
  • Do not substitute ONUREG® for intravenous or subcutaneous azacitidine

Myelosuppression1

  • New or worsening Grade 3 or 4 neutropenia and thrombocytopenia occurred in 49% and 22% of patients who received ONUREG®, respectively
  • Febrile neutropenia occurred in 12%
  • A dose reduction was required for 7% and 2% of patients due to neutropenia and thrombocytopenia, respectively
  • <1% of patients discontinued ONUREG® due to either neutropenia or thrombocytopenia
  • Monitor complete blood counts and modify the dosage as recommended
  • Provide standard supportive care, including hematopoietic growth factors, if myelosuppression occurs

Increased early mortality in patients with myelodysplastic syndromes1

  • In AZA-MDS-003 (NCT01566695), 216 patients with red blood cell transfusion-dependent anemia and thrombocytopenia due to myelodysplastic syndromes were randomized to ONUREG® or placebo
  • 107 patients received a median of 5 cycles of ONUREG® 300 mg daily for 21 days of a 28-day cycle
  • Enrollment was discontinued early due to a higher incidence of early fatal and/or serious adverse reactions in patients who received ONUREG® compared with placebo
  • The most frequent fatal adverse reaction was sepsis
  • The safety and effectiveness of ONUREG® for treatment of myelodysplastic syndromes have not been established
  • Treatment of patients with myelodysplastic syndromes with ONUREG® is not recommended outside of controlled trials

Embryo-fetal toxicity1

  • Based on the mechanism of action and findings in animals, ONUREG® can cause fetal harm when administered to a pregnant woman
  • Azacitidine administered to pregnant rats via a single intraperitoneal dose less than the recommended human daily dose of oral azacitidine on a mg/m2 basis caused fetal death and anomalies
  • Advise pregnant women of the potential risk to a fetus
  • Advise females of reproductive potential to use effective contraception during treatment with ONUREG® and for at least 6 months after the last dose
  • Advise males with female partners of reproductive potential to use effective contraception during treatment with ONUREG® and for at least 3 months after the last dose
Warnings and Precautions Adverse Reactions Discontinuations and Dose Modifications

ONUREG® safety was assessed in the QUAZAR® AML-001 trial1

  • 1 fatal AR (sepsis) occurred in a patient who received ONUREG®1
  • Serious ARs occurred in 15% of patients receiving ONUREG®1
    • Serious ARs in ≥2% of patients who received ONUREG® were pneumonia (8%) and febrile neutropenia (7%)

The majority of adverse reactions (ARs) were mild to moderate (Grade 1 or 2) with ONUREG®1

ARs (≥5%) in patients with AML who received ONUREG® with a difference between arms of >2% compared with placebo in QUAZAR® AML-0011
