289P - Risk factors for interstitial lung disease in patients treated with trastuzumab deruxtecan from two interventional studies
- Charles A. Powell (New York, United States of America)
Abstract
Background
Trastuzumab deruxtecan (T-DXd; DS-8201) is a HER2-targeted antibody drug conjugate with demonstrated antitumor activity and manageable safety profile in HER2-expressing/mutated solid tumors. Interstitial lung disease (ILD) is an important identified risk for patients (pts) treated with T-DXd. We report incidence of independently adjudicated drug-related ILD events and explore potential risk factors.
Methods
A post hoc analysis was conducted of pooled data from 542 pts who received at least one dose of 1.6, 3.2, 5.4, 6.4, 7.4, or 8.0 mg/kg T-DXd in two open-label interventional studies in advanced solid tumors (NCT02564900) and breast cancer (BC) (NCT03248492) (data cutoff, August 1, 2019). Baseline characteristics, exposure, incidence, and time to onset were summarized. Potential risk factors were evaluated in a stepwise multivariable logistic regression model.
Results
437 (80.6%) pts had BC; the remainder consisted of other tumors across all doses. 234 (43%) pts were from Japan. Median treatment duration was 8.4 months (range, 0.7-46.0). Overall, 16.8% (91/542) pts experienced an ILD (grade ≥ 3: 20/542, 3.7%), of which 18.1% (79/437) all grade ILD was reported in BC. Median time to onset was 208 days (range, 0-582) in the overall population and 134 days (range, 35-338) in the BC 5.4 mg/kg group. Potential risk factors associated with drug-related ILD were country (Japan vs. non-Japan; OR 3.6; 95% CI, 2.1-6.1) and tumor type (BC vs. other tumors; OR, 2.5; 95% CI, 1.2-5.0). Additional results will be presented, including for the non BC patients.
Conclusions
In this population, higher incidence of ILD related to T-DXd treatment was observed among pts from Japan and those with BC. However, these results should be interpreted with caution given that the majority of patients in the analysis had BC.
