Study Comparing Rovalpituzumab Tesirine Versus Topotecan in Subjects With Advanced or Metastatic Small Cell Lung Cancer With High Levels of Delta-like Protein 3 (DLL3) and Who Have First Disease Progression During or Following Front-line Platinum-based Chemotherapy (TAHOE)

The purpose of this randomized, open-label, 2-arm, phase 3 study is to assess the efficacy, safety and tolerability of rovalpituzumab tesirine versus topotecan in participants with advanced or metastatic SCLC with high levels of DLL3, who have first disease progression during or following front-line platinum-based chemotherapy.
