1. Patients who have only had 1 line of platinum-based therapy must have received at
least 4 cycles of platinum, must have had a response [complete response/remission
(CR) or partial response/remission (PR)], and then progressed between 3 months
and ≤ 6 months after the date of the last dose of platinum

least 4 cycles of platinum and then progressed within 6 months after the date of
the last dose of platinum

a. Prior treatment with bevacizumab is required for patients with 1 to 2 prior lines
of therapy
- Patients must be willing to provide an archival tumor tissue block or slides or if not
available, undergo procedure to obtain a new tumor biopsy using a low-risk, medically
routine procedure
Ovarian Cancer Exclusion Criteria for UPLIFT:
- Low-grade, clear cell, endometrioid, mucinous, carcinosarcoma, germ-cell, mixed
histology, or stromal tumors
- Prior treatment with mirvetuximab soravtansine or another ADC containing an
antitubulin payload
- Primary platinum-resistant disease, defined by a lack of response or by progression
within 3 months after completing front-line, platinum-containing therapy.
- Participation in DES or EXP segments of this study
Ovarian Cancer Inclusion Criteria for Expansion:
- Histological diagnosis of high grade serous ovarian cancer, which includes fallopian
tube, or primary peritoneal cancer, that is metastatic or recurrent.
- One to 3 prior lines of systemic therapy for ovarian cancer including at least 1 prior
line of a platinum-containing regimen. These patients must have platinum-resistant
disease, defined as completing 4 or more cycles of platinum-based therapy and
progressing within 6 months of last platinum-based therapy.
1. Patients with 4 lines of prior systemic therapy regardless of platinum
sensitivity status may be enrolled at the Investigator's discretion and upon
written approval by the Sponsor Medical Monitor.
2. Maintenance therapy, e.g., a PARP-inhibitor or bevacizumab given after a
platinum-containing regimen, will not count as a separate line of therapy.
- Tumor sample must be provided from both timepoints.
1. An archived tumor sample
2. A recent tumor biopsy (if medically feasible). If a recent biopsy cannot be
obtained, enrollment requires written approval by the Sponsor Medical Monitor.
