INTRODUCTION
Immune checkpoint inhibitors (ICIs) have significantly
improved survival in various solid tumors. With the
increasing use of these agents, the number of
autoimmune toxicities—known as immune-related
adverse events (irAEs)—has risen.The incidence of
irAEs in patients receiving ICI therapy is estimated to
range between 60% and 85%.Renal irAEs are less
common compared to dermatologic, gastrointestinal,
and other organ toxicities.
RESULTS
AIM
This study aims to evaluate the incidence and
frequency of immune-related nephropathy among
patients treated with different ICIs, as reported in the
FDA adverse event reporting system (FAERS)
between 2020 and 2024.
METHOD
• The FDA Adverse Event Reporting System
(FAERS) is a publicly accessible database that
collects reports on adverse drug events.
• Data for this study were obtained from the publicly
available version of the FAERS database, covering
the period from January 2020 to December 2024..
• Five ICIs associated with immune-related
nephropathy were included in the analysis:
• AntiPD1agents: pembrolizumab and nivolumab
• Anti-PD-L1agents:atezolizumab,avelumab, and
durvalumab
• A total of 137,286 adverse events were
reported in the FAERS database between
January 2020 and December 2024.
• Immune-related nephropathy was identified
in 6,482 cases (4.7%).
• This condition was most frequently reported:
• In male patients (57.6%)
• In the 65–85 age group (50.9%)
• Distribution of immune-related nephropathy
by ICI (Figure 1):
✓ Pembrolizumab: 2,761 cases (5.1%)
✓ Nivolumab: 2,424 cases (5.3%)
✓ Durvalumab: 257 cases (2.2%)
✓ Atezolizumab: 928 cases (3.7%)
✓ Avelumab: 112 cases (4.7%)
• A statistically significant difference was
observed between individual ICIs (p < 0.01)
• A statistically significant difference in the
incidence of nephropathy was noted
between PD-1 and PD-L1 inhibitor groups
(5.2% vs 3.4%, p < 0.01) (Figure 2).
• No significant difference was found among
PD-1 inhibitors.
• A significant difference was found among
PD-L1 inhibitors;
✓ Avelumab vs Durvalumab: p < 0.01
✓ Avelumab vs Atezolizumab: p = 0.01
✓ Durvalumab vs Atezolizumab: p < 0.01
CONCLUSIONS
• ICI-associated acute kidney injury (ICI-AKI) is
a rare complication, reported in approximately
2–5% of patients receiving ICI therapy
• In our study, the frequency of renal irAEs was
found to be 4.7%
• Our study demonstrates significant variability
in the incidence of immune-related
nephropathy among different ICIs, with higher
frequencies observed in PD-1 inhibitors
• Among PD-L1 inhibitors, notable differences
were also detected, underscoring the
importance of vigilant renal monitoring during
ICI therapy
