Progression-free survival defined as assessed by BICR per RECIST v1.1, defined as the time from date of randomization until BICR-assessed PD or death due to any cause, whichever occurs first
TEAEs defined as any adverse event (AE) with the onset after the first dose of study drug until 30 days after the last dose of the study drug.
TEAEs defined as any adverse event (AE) with the onset after the first dose of study drug until 30 days after the last dose of the study drug.
An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment.
OR is defined as achieving a best overall response of confirmed complete response (CR) or confirmed partial response (PR) based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
PFS is defined as the time from the date of randomization to the first occurrence of radiographic progression based on RECIST version 1.1 or death from any cause, whichever occurs first.
ORR was defined as percentage of participants with a confirmed best overall response (BOR) of complete response (CR) or partial response (PR). CR: Disappearance of all target or non-target lesions. All pathological or non-pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 millimeters (mm). PR: At least 30% decrease in the sum of the longest diameters (SoD) of target lesions, taking as reference the baseline SoD.
To assess percentage of patients with advanced-stage ovarian, fallopian tube, and peritoneal cancers per Response Evaluation Criteria in Solid Tumors (RECIST)1.1 and Gynecological Cancer Intergroup Cancer antigen 125 (GCIG CA-125) criteria.
To assess ORR per iRECIST 1.1 and GCIG CA-125 criteria
Radiographic tumor response by CT or MRI of chest, abdomen, and pelvis using RECIST v1.1

| mirvetuximab soravtansine (MIRV; IMGN853) | DRUG | Mirvetuximab soravtansine (also known as IMGN853 and MIRV) is an antibody-drug conjugate (ADC) that consists of a high affinity humanized monoclonal antibody against folate receptor α (FRα, the protein product of the folate receptor 1 \[FOLR1\] gene) that is conjugated to a cytotoxic maytansinoid by the hindered disulfide succinimidyl 4-(pyridin-2-yl)disulfanyl)-2-sulfo-butyrate linker (sulfo-SPDB) linker. FRα is a glycosyl-phosphatidylinositol (GPI)-linked protein, which shows limited normal tissue expression and high expression on the surface of solid tumors, particularly epithelial ovarian cancer, fallopian tube cancer, and primary peritoneal cancer (referenced herein collectively as EOC), endometrial cancer, non-small cell lung cancer (NSCLC), and renal cell cancer. |
Inclusion Criteria: 1. Adult women \>/=18 years old 2. Confirmed diagnosis of high-grade serous epithelial ovarian, primary peritoneal, or fallopian tube cancer 3. Confirmed high FRα expression by regulatory-agency approved Ventana FOLR1 (FOLR1-2.1) 4. Relapsed disease after frontline (first-line) ...

Mirvetuximab Soravtansine is an investigational oncology drug being studied for the treatment of ovarian cancer, including advanced high-grade epithelial ovarian cancer, recurrent ovarian cancer, and high-grade ovarian cancer. It is also being evaluated in related conditions such as primary peritoneal cancer and fallopian tube cancer.
Mirvetuximab Soravtansine targets FOLR1, also known as folate receptor-alpha (FRα). It is a binding agent designed to interact with this receptor, which is expressed on certain cancer cells. The drug is being studied in patients whose tumors have high FRα expression.
Mirvetuximab Soravtansine is being developed by AbbVie Inc., a biopharmaceutical company traded on the New York Stock Exchange under the ticker ABBV. AbbVie is conducting clinical trials to evaluate the drug's safety and efficacy in ovarian cancer and related conditions.
Mirvetuximab Soravtansine is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The drug is being studied in multiple clinical trials, including Phase 2 and Phase 3 studies, to assess its effects in patients with ovarian cancer.
Mirvetuximab Soravtansine is being studied in four clinical trials. NCT04209855 is a completed Phase 3 study in platinum-resistant ovarian cancer. NCT05445778 is an active Phase 3 trial testing the drug with bevacizumab as maintenance therapy. NCT06682988 and NCT06890338 are recruiting Phase 2 studies evaluating the drug in advanced ovarian cancer and newly diagnosed disease, respectively.
Mirvetuximab Soravtansine is the same drug as mirvetuximab soravtansine (MIRV; IMGN853). The combination of Mirvetuximab Soravtansine with Bevacizumab is a specific treatment regimen being tested in clinical trials, such as NCT05445778, where the two drugs are administered together as maintenance therapy for ovarian cancer.
