6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of REVUFORJ reflects exposure in 241 patients (207 adult and 34 pediatric patients) with relapsed or refractory (R/R) acute leukemia with a KMT2A translocation or an NPM1 mutation treated with REVUFORJ at a dose approximately equivalent to 160 mg in adults orally twice daily with a strong CYP3A4 inhibitor [see Clinical Studies (14) ] .
The median duration of exposure to REVUFORJ was 2.5 months (range < 1 to 40 months), and 10% of patients were exposed for more than 6 months.
Fatal adverse reactions occurred in 9 (4%) patients who received REVUFORJ, including 4 with sudden death, 2 with differentiation syndrome, 2 with hemorrhage, and 1 with cardiac arrest.
Serious adverse reactions were reported in 184 (76%) patients.
The most frequent serious adverse reactions (≥ 10%) were infection (29%), febrile neutropenia (20%), bacterial infection (15%), differentiation syndrome (13%), and hemorrhage (11%).
Adverse reactions leading to dose interruption occurred in 49% of patients.
The most common adverse reactions (≥ 5%) leading to dose interruption were electrocardiogram QT prolonged, infection, febrile neutropenia, differentiation syndrome, nausea, and hypokalemia.
5 WARNINGS AND PRECAUTIONS Embryo-Fetal Toxicity : Can cause fetal harm.
Advise females of reproductive potential and males with female partners of reproductive potential of potential risk to a fetus and to use effective contraception .
( 5.3 , 8.1 , 8.3 ) 5.1 Differentiation Syndrome REVUFORJ can cause fatal or life-threatening differentiation syndrome (DS).
Symptoms of differentiation syndrome, including those seen in patients treated with REVUFORJ, include fever, dyspnea, hypoxia, peripheral edema, pleuropericardial effusion, acute renal failure, rash, and/or hypotension.
In clinical trials, DS occurred in 60 (25%) of 241 patients treated with REVUFORJ at the recommended dosage for relapsed or refractory acute leukemia [see Adverse Reactions (6.1) ] .
Like all medications, Revuforj can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
