ABSTRACT
BACKGROUND: Daratumumab and isatuximab are anti-CD38 monoclonal antibodies indicated for the treatment of multiple myeloma. These agents can increase the risk of infectious complications, including viral infections. Cases of hepatitis B virus (HBV) reactivation have been reported in the literature in patients receiving anti-CD38 monoclonal antibody-based therapies.
AIM: The objective of this analysis was to determine if the association between anti-CD38 monoclonal antibody exposure and the development of hepatitis B reactivation had a detectable reporting signal in the United States Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS).
METHOD: We conducted a post marketing pharmacovigilance analysis by querying the FAERS for reports of HBV reactivation with daratumumab or isatuximab exposure reported between 2015 and 2022. Disproportionality signal analysis was conducted by calculating reporting odds ratios (RORs).
RESULTS: Sixteen cases of hepatitis B virus reactivation were reported in the FAERS database among patients receiving daratumumab or isatuximab reported between 2015 and 2022. The ROR for HBV reactivation was statistically significant for both daratumumab (ROR 4.76, 95% CI 2.76-8.22) and isatuximab (ROR 9.31, 95% CI 3.00-28.92).
CONCLUSION: Overall, our analysis demonstrates a significant reporting signal for HBV reactivation with daratumumab and isatuximab.
