A Study of TAK-853 in Adult Participants With Folate Receptor Alpha-Positive Advanced Ovarian Cancer And Other Solid Tumors

The main aim of this study are to check for side effects from TAK-853, check how much TAK-853 participants can receive without getting side effects from it, check how well TAK-853 controls symptoms, and to check how much TAK-853 stays in their blood over time. The study will be conducted in two phases including Phase 1 Part and Phase 2 Part. In Phase 1 Part, the participants will stay in the hospital for 3 days at least after their 1st injection for some tests and to check for any side effects from their treatment. In Phase 2 Part, participants will visit their study hospital for multiple times. In both phases, the participants will receive TAK-853 on the first days of each 3-week cycle. The participant will be in the study for about 9 months in Phase 1 Part and for about 24 months in Phase 2 Part. The study doctors will check for side effects from the study treatments.
