TROPION-Lung01 Study Design and Baseline demographics

DESTINY-Pan Tumor02: a Phase 2 study of T-DXd for HER2-expressing solid tumors An open-label, multicenter study (NCT04482309) • Key eligibility criteria Advanced solid tumors not eligible for curative therapy • 2L+ patient population ⚫ HER2 expression (IHC 3+ or 2+) Endometrial cancer Cervical cancer Daiichi-Sankyo - Local test or central test by Hercep Test if local test T-DXd Ovarian cancer not feasible (ASCO/CAP gastric cancer scoring 1)a 5.4 mg/kg Q3W Bladder cancer • Prior HER2-targeting therapy allowed · ECOG/WHO PS 0-1 Baseline characteristics • ⚫ 267 patients received treatment; 202 (75.7%) based on local HER2 testing 40 per cohortb Other tumorsc Biliary tract cancer - 111 (41.6%) patients were IHC 3+ based on HER2 test (local or central) at enrollment, primary efficacy analysis (all patients) 75 (28.1%) patients were IHC 3+ on central testing, sensitivity analysis on efficacy endpoints (subgroup analyses) Pancreatic cancer Primary endpoint • Confirmed ORR (investigator) Secondary endpoints DOR, DCR, PFS, OS Exploratory analysis • Subgroup analyses by HER2 status Primary analysis data cutoff: Jun 8, 2023 Median follow up: 12.75 mo • • Safety • Median age was 62 years (23-85) and 109 (40.8%) patients had received ≥3 lines of therapy *Patients were eligible for either test. All patients were centrally confirmed; 'planned recruitment, cohorts with no objective responses in the first 15 patients were to be closed; "patients with tumors that express HER2, excluding tumors in the tumor- specific cohorts, and breast cancer, non-small cell lung cancer, gastric cancer, and colorectal cancer 2L, second-line; ASCO, American Society of Clinical Oncology; CAP, College of American Pathologists; DCR, disease control rate; DOR, duration of response; ECOG, Eastern Cooperative Oncology Group; HER2, human epidermal growth factor receptor 2; IHC, immunohistochemistry; ORR, objective response rate; OS, overall survival; PFS, progression-free survival; PS, performance status; Q3W, every 3 weeks; T-DXd, trastuzumab deruxtecan; WHO, World Health Organization 1.
