Adverse reactions
6. ADVERSE REACTIONS The following clinically significant adverse reactions are discussed elsewhere in the labeling: Hepatotoxicity, Including Hepatic VOD (also known as Sinusoidal Obstruction Syndrome) [see Warnings and Precautions ( 5.1 )] Infusion-Related Reactions [see Warnings and Precautions ( 5.2 )] Edema [see Warnings and Precautions ( 5.3 )] The most common adverse reactions (≥20%) were edema, fatigue, musculoskeletal pain, hemorrhage, infusion-related reactions, nausea, and diarrhea.
( 6.1 ) The most common Grade 3 or 4 laboratory abnormalities (≥10%) were neutrophils decreased, platelets decreased, lymphocyte count decreased, white blood cells decreased, hemoglobin decreased, and glucose increased.

6.1Clinical
T rials 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 DECNUPAZ was evaluated in CADENZA, a single-arm, open-label study that included 116 adults with newly diagnosed or relapsed/refractory myeloid malignancies, including 84 with BPDCN, treated with DECNUPAZ 0.045 mg/kg once every three weeks.
The median number of cycles administered was 3 (range: 1 to 34) in the overall population, and 3.5 (range: 1 to 34) in patients with BPDCN. Serious adverse reactions occurred in 55% of patients treated with DECNUPAZ. The most common (≥2%) serious adverse reactions were febrile neutropenia, pneumonia, edema, sepsis, hemorrhage, thrombosis, infusion-related reactions, viral infection, pneumonitis, infections without specified pathogens, pyrexia, and musculoskeletal pain.
Fatal adverse reactions occurred in 4.3% of patients who received DECNUPAZ, including cardiac arrest (0.9%), clostridium difficile infection (0.9%), failure to thrive (0.9%), depressed level of consciousness (0.9%), and respiratory failure (0.9%). Permanent discontinuation due to adverse reactions occurred in 10% of patients who received DECNUPAZ. Adverse reactions which resulted in permanent discontinuation of DECNUPAZ in ≥1% of patients included veno-occlusive disease and pneumonitis.
Dosage interruptions of DECNUPAZ due to adverse reactions occurred in 37% of patients. Adverse reactions which resulted in dosage interruptions in ≥2% of patients included edema, pneumonia, infusion-related reaction, bacterial infections, fatigue, hemorrhage, neutropenia, pneumonitis, and pyrexia. Dose reductions of DECNUPAZ due to an adverse reaction occurred in 6% of patients. Adverse reactions which required dose reductions in ≥2% of patients included edema.
The most common adverse reactions (≥20%) were edema, fatigue, musculoskeletal pain, hemorrhage, infusion-related reactions, nausea, and diarrhea. The most common Grade 3 to 4 laboratory abnormalities (≥10%) were neutrophils decreased, platelets decreased, lymphocyte count decreased, white blood cells decreased, hemoglobin decreased, and glucose increased. Table 3 summarizes the common adverse reactions (≥10%) in patients treated with DECNUPAZ in CADENZA.
