Description
Summary
This Phase 3 study is designed to compare the efficacy and safety of mirvetuximab soravtansine vs. investigator's choice chemotherapy in patients with platinum-resistant high-grade epithelial ovarian cancer, primary peritoneal, or fallopian tube cancer, whose tumors express a high-level of FRα. Patients will be, in the opinion of the Investigator, appropriate for single-agent therapy for their next line of therapy. Folate receptor alpha (FRα) positivity will be defined by the Ventana FOLR1 (FOLR1-2.1) CDx assay.
Official Title
MIRASOL: A Randomized, Open-label, Phase 3 Study of Mirvetuximab Soravtansine vs. Investigator's Choice of Chemotherapy in Platinum-Resistant, Advanced High-Grade Epithelial Ovarian, Primary Peritoneal, or Fallopian Tube Cancers With High Folate Receptor-Alpha Expression
Details
Patients will be randomized to either mirvetuximab soravtansine (MIRV) or Investigator's Choice chemotherapy (paclitaxel, PEGylated liposomal doxorubicin, or topotecan).

Eligibility
You can join if…
Open to females ages 18 years and up
- Female patients ≥ 18 years of age
- Patients must have a confirmed diagnosis of high-grade serious epithelial ovarian cancer, primary peritoneal cancer, or fallopian tube cancer
- Patients must have platinum-resistant disease:
- 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 (CR or PR) and then progressed between >3 months and ≤ 6 months after the date of the last dose of platinum
Patients 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: Patients who are platinum-refractory during front-line treatment are excluded
- Patients must have progressed radiographically on or after their most recent line of therapy
- Patients 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 IHC confirmation of FRα positivity
- Patient's tumor must be positive for FRα expression as defined by the Ventana FOLR1 (FOLR-2.1) CDx assay
- Patients must have at least one lesion that meets the definition of measurable disease by RECIST v1.1 (radiologically measured by the Investigator)
- Patients 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 (eg, bevacizumab, PARP inhibitors) will be considered as part of the preceding line of therapy (ie, not counted independently)
- Therapy changed due to toxicity in the absence of progression will be considered as part of the same line (ie, not counted independently)
- Hormonal therapy will be counted as a separate line of therapy unless it was given as maintenance
Patient must have an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 or 1
10. Time from prior therapy:
- Systemic antineoplastic therapy (5 half-lives or 4 weeks, whichever is shorter)
- Focal radiation completed at least 2 weeks prior to first dose of study drug
- Patients must have stabilized or recovered (Grade 1 or baseline) from all prior therapy-related toxicities
- Major surgery must be completed at least 4 weeks prior to first dose and have recovered or stabilized from the side effects of prior surgery
- Patients must have adequate hematologic, liver and kidney functions defined as:
- Absolute neutrophil count (ANC) ≥ 1.5 x 109/L (1,500/μL) without G-CSF in the prior 10 days or long-acting WBC growth factors in the prior 20 days
- Platelet count ≥ 100 x 109/L (100,000/μL) without platelet transfusion in the prior 10 days
- Hemoglobin ≥ 9.0 g/dL without packed red blood cell (PRBC) transfusion in the prior 21 days
- Serum creatinine ≤ 1.5 x upper limit of normal (ULN)
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3.0 x ULN
- Serum bilirubin ≤ 1.5 x ULN (patients with documented diagnosis of Gilbert syndrome are eligible if total bilirubin < 3.0 x ULN
- Serum albumin ≥ 2 g/dL

- Women of childbearing potential (WCBP) must agree to use highly effective contraceptive method(s) (as defined in Section 5.9.6 in the protocol) while on study drug and for at least 3 months after the last dose of MIRV or at least 6 months after the last dose of paclitaxel, pegylated liposomal doxorubicin, or topotecan
- WCBP must have a negative pregnancy test within 4 days prior to the first dose of study drug
- Patients must have stabilized or recovered (Grade 1 or baseline) from all prior therapy-related toxicities
