Preventing Dato-DXd Associated Stomatitis With Dexamethasone Mouthwash, TROPION-DM (NCT06974604)
🩺 Plain-English Summary (8th-Grade Level)
TROPION-DM/BrUOG-431 is a prospective, , phase 2 trial with two non-comparative cohorts analyzed jointly for primary endpoint in adult patients with either (Cohort 1:) advanced/metastatic hormone-receptor positive (\[HR+\], estrogen receptor and/or progesterone receptor positive) breast cancer (BC), or advanced/metastatic triple negative breast cancer (TNBC) or (Cohort 2:) advanced/metastatic non-squamous non-small cell lung cancer (NSCLC). All patients will be treated with Datopotumab deruxtecan (Dato-DXd) at 6 mg/kg IV every 3 weeks until disease progression or unacceptable toxicity. Due to the risk of stomatitis, the investigational component of this trial will be to incorporate alcohol-free dexamethasone mouthwash, 10 mL 0.5 mg/5mL oral solution, days 1-5, swish and spit four times daily for the first 3 cycles.
