ABSTRACT
Background
Interstitial lung disease (ILD) events associated with anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugates (ADCs) have aroused wide attention.
Research design and methods
In meta-analysis, we systematically reviewed literatures, and the outcomes were the proportion and risk of ILD related to anti-HER2 ADCs. A disproportionality analysis based on data from VigiBase was conducted to characterize the main features of anti-HER2 ADC-related ILD/pneumonitis.
Results
Two hundred and forty-five all-grade and 47 grade ≥ 3 ILD events with the proportion of 4.4% (95% confidence interval (CI) [2.0%, 6.8%]) and 0.5% (95% CI [0.3%, 0.8%]) were observed for anti-HER2 ADCs, respectively. Trastuzumab emtansine, trastuzumab deruxtecan and trastuzumab duocarmazine significantly increased the risk of all-grade and grade ≥ 3 ILD events with Peto odd ratios of 2.62 (95% CI [1.71, 4.04], P < 0.0001) and 2.82 (95% CI [1.07, 7.42], P = 0.04), respectively. In VigiBase, 271 cases of ILD/pneumonitis related to trastuzumab emtansine and trastuzumab deruxtecan were extracted. The median time to the onset of event was 86 days and 54.95% of events occurred within 3 months.
Conclusions
Trastuzumab emtansine, trastuzumab deruxtecan and trastuzumab duocarmazine increased the risk of ILD, which can lead to serious outcomes and tends to occur early.
