CLINICAL NEWS Literature Scan Continued from page 22 New Agent PER977 Shows Promise in Reversing Anticoagulation Although newer target-specific oral anticoagulants represent great advances in the prevention and treatment of blood clots, their use is limited by a lack of effective reversal agents. Severe or life-threatening bleeding thus remains a dangerous GAZYVA® (obinutuzumab) Injection, for intravenous infusion Initial U.S. Approval: 2013 This is a brief summary of information about GAZYVA. Before prescribing, please see full Prescribing Information. WARNING: HEPATITIS B VIRUS REACTIVATION AND PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY • Hepatitis B Virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients receiving CD20-directed cytolytic antibodies, including GAZYVA. Screen all patients for HBV infection before treatment initiation. Monitor HBV positive patients during and after treatment with GAZYVA. Discontinue GAZYVA and concomitant medications in the event of HBV reactivation [see Warnings and Precautions (5.1)]. • Progressive Multifocal Leukoencephalopathy (PML) including fatal PML, can occur in patients receiving GAZYVA [see Warnings and Precautions (5.2)]. 1 INDICATIONS AND USAGE GAZYVA, in combination with chlorambucil, is indicated for the treatment of patients with previously untreated chronic lymphocytic leukemia (CLL) [see Clinical Studies (14.1)]. 4 CONTRAINDICATIONS None. 5 WARNINGS AND PRECAUTIONS 5.1 Hepatitis B Virus Reactivation Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure and death, can occur in patients treated with anti-CD20 antibodies such as GAZYVA. HBV reactivation has been reported in patients who are hepatitis B surface antigen (HBsAg) positive and also in patients who are HBsAg negative but are hepatitis B core antibody (anti-HBc) positive. Reactivation has also occurred in patients who appear to have resolved hepatitis B infection (i.e., HBsAg negative, anti-HBc positive, and hepatitis B surface antibody [anti-HBs] positive). HBV reactivation is defined as an abrupt increase in HBV replication manifesting as a rapid increase in serum HBV DNA level or detection of HBsAg in a person who was previously HBsAg negative and anti-HBc positive.
