SIGNS OF RENAL OR PULMONARY DYSFUNCTION
Be alert for the possible signs of renal or pulmonary dysfunction
Renal dysfunction may include1-4
- Decreased urinary output
- Elevated creatinine levels (≥1.5 x baseline)
- Decreased creatinine clearance
- Decreased glomerular filtration rate
- Need for dialysis
Pulmonary dysfunction may include2,3,5
- Pulmonary infiltrates
- Pleural effusion
- Reduced oxygen saturation
- Need for supplemental oxygen (nasal cannula)
- Ventilator dependence
30% TO 50%
of cases developed multi-organ dysfunction6,a
overall mortality in VOD with multi-organ dysfunction7,b
aBased on a study conducted by Carreras et al that used 2 sets of diagnostic criteria to estimate the incidence of VOD after HSCT.
bBased on 19 studies (235 patients) that specifically determined mortality from severe VOD, as reported within a meta-analysis of 135 studies performed between 1979 and 2007.
Defitelio® (defibrotide sodium) is indicated for the treatment of adult and pediatric patients with hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), with renal or pulmonary dysfunction following hematopoietic stem-cell transplantation (HSCT).
IMPORTANT SAFETY INFORMATION
Defitelio is contraindicated in the following conditions:
- Concomitant administration with systemic anticoagulant or fibrinolytic therapy
- Known hypersensitivity to Defitelio or to any of its excipients
Warnings and Precautions
Defitelio may increase the risk of bleeding in patients with VOD after HSCT. Do not initiate Defitelio in patients with active bleeding. Monitor patients on Defitelio for signs of bleeding. If bleeding occurs, withhold or discontinue Defitelio.
Concomitant systemic anticoagulant or fibrinolytic therapy may increase the risk of bleeding and should be discontinued prior to Defitelio treatment. Consider delaying Defitelio administration until the effects of the anticoagulant have abated.
Hypersensitivity reactions including rash, urticaria, and angioedema have occurred in less than 2% of patients treated with Defitelio. One case of an anaphylactic reaction was reported in a patient who had previously received Defitelio. Monitor patients for hypersensitivity reactions, especially if there is a history of previous exposure. If a severe hypersensitivity reaction occurs, discontinue Defitelio, treat according to the standard of care, and monitor until symptoms resolve.
Most Common Adverse Reactions
The most common adverse reactions (incidence ≥10% and independent of causality) with Defitelio treatment were hypotension, diarrhea, vomiting, nausea, and epistaxis.Please see full Prescribing Information.
