Although antibody-drug conjugate(ADC) has proved effective in treating many cancers, few patients receiving ADC may experience rare but life-threatening sepsis-related toxicities such as sepsis and septic shock. Today, data about sepsis/septic shock are scarce.

The objective was to investigate reports of sepsis/septic shock adverse events related to ADC, including Gemtuzumab Ozogamicin, Trastuzumab Emtansine, Inotuzumab Ozogamicin, Enfortumab vedotin, Trastuzumab deruxtecan, Sacituzumab govitecan, Brentuximab Vedotin, Moxetumomab pasudotox, Polatuzumab Vedotin, Belantamab Mafodotin, loncastuximab tesirine and Tisotumab vedotin using international pharmacovigilance databases such as the FDA Adverse Event Reporting System (FAERS).

Here, investigators use international pharmacovigilance databases such as the FDA Adverse Event Reporting System (FAERS) of individual safety case reports, to identify cases of sepsis-related toxicities related to ADC.

Inclusion Criteria:

Case reported in the FDA Adverse Event Reporting System (FAERS) or other international pharmacovigilance database of individual safety case reports to 12/31/2022 Adverse event reported were included the report with MedDRA terms: Sepsis(SMQ), agranulocytosis(SMQ), Opportunistic infections (SMQ).

Patients treated with ADC included: Gemtuzumab Ozogamicin, Trastuzumab Emtansine, Inotuzumab Ozogamicin, Enfortumab vedotin, Trastuzumab deruxtecan, Sacituzumab govitecan, Brentuximab Vedotin, Moxetumomab pasudotox, Polatuzumab Vedotin, Belantamab Mafodotin, loncastuximab tesirine and Tisotumab vedotin. Other cancer patients received common drug therapies such as chemotherapy, targeted therapy or immunotherapy would also be included as a comparator.

Exclusion Criteria:

Chronology not compatible between ADC and adverse event (sepsis-related toxicities)

Cancer patients treated with antibody-drug conjugate and experiencing sepsis-related toxicities.
