A Phase 3 Multicenter Double-blind Randomized Study of Taletrectinib Versus Placebo in Patients With ROS1-Fusion Positive Stage IB-IIIA Non-Small Cell Lung Cancer Who Have Undergone Complete Tumor Resection
The purpose of this phase 3 multicenter double-blind randomized study is to assess the use of taletrectinib in the early-stage non-small cell lung cancer (NSCLC). The study compares taletrectinib (study drug) versus placebo (sugar pill) in patients with ROS1-fusion positive stage IB, II, IIIA NSCLC. The study will evaluate if taletrectinib is better than placebo at preventing the participant's disease from coming back after the participant's lung tumor was removed.
• Histologically confirmed stage IB, II, or IIIA NSCLC (AJCC 9th edition) based on pathological staging.
• Documented ROS1 rearrangement in primary tumor by a validated local assay performed in CLIA-certified or locally equivalent diagnostic laboratories.
• Adequate tissue is available for prospective central laboratory confirmatory testing. Confirmation of central test positivity is required prior to Randomization.
• Note: In the event that the local testing assay is the same as the central testing assay, and the local test was conducted in a CLIA-certified laboratory or local equivalent, prospective central confirmation is not needed, but tumor tissue must still be provided for other biomarker studies.
• Age ≥18 years (or ≥20 years as required by local regulations).
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Received definitive locoregional curative surgery for stage IB, II, or IIIA NSCLC. All surgical margins of resection must be negative for tumor.
• Complete recovery from surgery (including complete wound healing) that was performed ≥4 weeks but no more than 16 weeks before Randomization if no adjuvant chemotherapy was given. Surgery must have occurred ≥4 weeks but no more than 30 weeks prior to Randomization if adjuvant chemotherapy was given. For participants who received post-resection adjuvant chemotherapy, the final dose of chemotherapy must also have occurred at least 7 days before Randomization. All chemotherapy related toxicities must have resolved to baseline or ≤Grade 1 (per CTCAE v5.0) prior to Randomization.
