BESPONSA™ Patient Counseling Information (inotuzumab ozogamicin)


Hepatotoxicity, Including Hepatic Veno-occlusive Disease (VOD) (also known as Sinusoidal Obstruction Syndrome)

Inform patients that liver problems, including severe, life-threatening, or fatal VOD, and increases in liver tests may develop during BESPONSA treatment. Inform patients that they should seek immediate medical advice if they experience symptoms of VOD, which may include elevated bilirubin, rapid weight gain, and abdominal swelling that may be painful. Inform patients that they should carefully consider the benefit/risk of BESPONSA treatment if they have a prior history of VOD or serious ongoing liver disease [see Warnings and Precautions (5.1)].

Increased Risk of Post-HSCT Non-Relapse Mortality

Inform patients that there is an increased risk of post-HSCT non-relapse mortality after receiving BESPONSA, that the most common causes of post-HSCT non-relapse mortality included infection and VOD. Advise patients to report signs and symptoms of infection [see Warnings and Precautions (5.2)].


Inform patients that decreased blood counts, which may be life-threatening, may develop during BESPONSA treatment and that complications associated with decreased blood counts may include infections, which may be life-threatening or fatal, and bleeding/hemorrhage events. Inform patients that signs and symptoms of infection, bleeding/hemorrhage, or other effects of decreased blood counts should be reported during treatment with BESPONSA [see Warnings and Precautions (5.3)].
