ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies: an infectious diseases perspective (Agents targeting lymphoid or myeloid cells surface antigens [II]: CD22, CD30, CD33, CD38, CD40, SLAMF-7 and CCR4)

Background: The present review is part of the ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies. Aims: To review, from an Infectious Diseases perspective, the safety profile of agents targeting CD22, CD30, CD33, CD38, CD40, SLAMF-7 and CCR4 and to suggest preventive recommendations. Sources: Computer-based MEDLINE searches with MeSH terms pertaining to each agent or therapeutic family. Content: The risk and spectrum of infections in patients receiving CD22-targeted agents (i.e. inotuzumab ozogamicin) are similar to those observed with anti-CD20 antibodies. Anti-Pneumocystis prophylaxis and monitoring for cytomegalovirus (CMV) infection is recommended for patients receiving CD30-targeted agents (brentuximab vedotin). Due to the scarcity of data, the risk posed by CD33-targeted agents (gemtuzumab ozogamicin) cannot be assessed. Patients receiving CD38-targeted agents (i.e. daratumumab) face an increased risk of varicella-zoster virus (VZV) infection. Therapy with CD40-targeted agents (lucatumumab or dacetuzumab) is associated with opportunistic infections similar to those observed in hyper-IgM syndrome, and prevention strategies (including anti-Pneumocystis prophylaxis and pre-emptive therapy for CMV infection) are warranted. SLAMF-7 (CD319)-targeted agents (elotuzumab) induce lymphopenia and increase the risk of infection (particularly due to VZV). The impact of CCR4-targeted agents (mogamulizumab) on infection susceptibility is difficult to distinguish from the effect of underlying diseases and concomitant therapies. However, anti-Pneumocystis and anti-herpesvirus prophylaxis and screening for chronic hepatitis B virus (HBV) infection are recommended. Implications: Specific management strategies should be put in place to reduce the risk and/or the severity of infectious complications associated to the reviewed agents.
