• Female participants ≥ 18 years of age
• Participants must have a confirmed diagnosis of high-grade serious epithelial ovarian cancer, primary peritoneal cancer, or fallopian tube cancer
• Participants must have platinum-resistant disease:
  • Participants who have only had 1 line of platinum based therapy must have received at least 4 cycles of platinum, must have had a response (CR or PR) and then progressed between >3 months and ≤ 6 months after the date of the last dose of platinum
  • Participants who have received 2 or 3 lines of platinum therapy must have progressed on or within 6 months after the date of the last dose of platinum Note: Progression should be calculated from the date of the last administered dose of platinum therapy to the date of the radiographic imaging showing progression. Note: Participants who are platinum-refractory during front-line treatment are excluded
• Participants must have progressed radiographically on or after their most recent line of therapy
• Participants must be willing to provide an archival tumor tissue block or slides, or undergo procedure to obtain a new biopsy using a low risk, medically routine procedure for immunohistochemistry (IHC) confirmation of FRα positivity

• Participants must have at least one lesion that meets the definition of measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (radiologically measured by the Investigator)
• Participants must have received at least 1 but no more than 3 prior systemic lines of anticancer therapy, and for whom single-agent therapy is appropriate as the next line of treatment:
  • Adjuvant ± neoadjuvant considered one line of therapy
  • Maintenance therapy (for example, bevacizumab, poly (ADP-ribose) polymerase [PARP] inhibitors) will be considered as part of the preceding line of therapy (that is, not counted independently)
  • Therapy changed due to toxicity in the absence of progression will be considered as part of the same line (that is, not counted independently)
