Summary

This study will compare the efficacy and safety of molecularly-guided therapy versus standard platinum-containing chemotherapy in participants with poor-prognosis cancer of unknown primary site (CUP; non-specific subset) who have achieved disease control after 3 cycles of first-line platinum based induction chemotherapy.
