Ovarian Cancer Clinical Trial

Mirvetuximab Soravtansine With Bevacizumab Versus Bevacizumab as Maintenance in Platinum-sensitive Ovarian, Fallopian Tube, or Peritoneal Cancer (GLORIOSA)

Summary

GLORIOSA is a Phase 3 multicenter, open label study designed to evaluate the safety and efficacy of Mirvetuximab Soravtansine in participants with platinum-sensitive ovarian, primary peritoneal or fallopian tube cancers with high folate receptor-alpha (FRα) expression.

Full Description

Mirvetuximab Soravtansine (MIRV) is an investigational antibody drug conjugate designed to selectively kill cancer cells. The antibody (protein) part of MIRV targets tumors by delivering a cell-killing drug to the tumor cells carrying a tumor-associated protein called folate receptor alpha (FRα). It is being developed for the treatment of subjects with recurrent platinum-sensitive, highgrade epithelial ovarian, primary peritoneal, or fallopian tube cancers with high folate receptor-alpha expression. Patients must have confirmation of FRα positivity by the Ventana FOLR1 Assay.

Eligibility Criteria

Inclusion Criteria:

Patients ≥ 18 years of age
Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Patients must have a confirmed diagnosis of high-grade serous epithelial ovarian, primary peritoneal, or fallopian tube cancer.
Patients must be willing to provide an archival tumor tissue block or slides, or must undergo a procedure to obtain a new biopsy using a low-risk, medically routine procedure for IHC confirmation of FRα positivity as defined by the Ventana FOLR1 Assay. Patients must be confirmed FRα-high as defined by FRα positivity of ≥ 75% of tumor membrane staining at ≥ 2+ intensity (PS2+) for entry into the study.

Prior BRCA testing on the tumor or prior germline testing is required for eligibility. If not done prior, tumor or germline testing will need to be done at study entry (Pre-screening). Somatic and germline BRCA-positive patients must have received prior treatment with a PARPi in maintenance following first-line treatment.

Note: Local tumor or germline BRCA testing will be acceptable for stratification. If the patient has not been tested, recommend archival tumor samples to be assessed for tissue BRCA. Patients with homologous recombination deficient-positive tumors who have received prior PARPi plus bevacizumab treatment are eligible.

Patients must have relapsed after 1 line (first line) of platinum-based chemotherapy and have platinum-sensitive disease defined as progression greater than 6 months from last dose of primary platinum therapy.
Patients must be appropriate for, currently be on, or have completed platinum-based triplet therapy in second line (recurrent platinum-sensitive, high-grade serous epithelial ovarian, primary peritoneal, or fallopian tube cancer)
Patients must have received no less than 4 and no more than 8 cycles of platinum-based triplet therapy in second line, to include no less than 3 cycles of bevacizumab in combination with platinum-based chemotherapy. If the number of cycles received is less than 6 due to toxicity, this must be documented and toxicity assessed as unlikely related to bevacizumab.
In the case of interval secondary cytoreductive surgery, patients are permitted to receive only 2 cycles of bevacizumab in combination with the last 3 cycles of platinum-based triplet therapy in the second line. In the case of primary cytoreductive surgery before second-line platinum-based triplet therapy, patients must have no less than 3 cycles of bevacizumab in combination with platinum-based chemotherapy after their surgery and before randomization.
Patients will either receive (per investigator's choice), must be receiving, or have received paclitaxel, gemcitabine, or PLD as the partner drug to platinum-based triplet therapy in the second line.
Patients must be in CR, PR, or SD, per the investigator, after completion of triplet therapy in second line to be eligible for randomization into the study population. All patients in both populations will have computed tomography (CT)/magnetic resonance imaging (MRI) scans and CA-125 measurements at least 3 weeks but no more than 8 weeks after their last planned dose of triplet therapy and before randomization.
Patients must be randomized no later than 8 weeks from the last dose of triplet therapy in second line.

After completion of triplet therapy and before randomization, patients must meet one of the following criteria:

Have at least 1 lesion that meets the definition of measurable disease by RECIST v1.1 (radiologically measured by the investigator), and determined by the investigator to either have SD or a PR to their treatment; or
Have persistently elevated CA-125 without measurable disease and determined by the investigator to either have SD or a PR to their treatment; or
Have clinically no evidence of disease by both radiographic interpretation by the investigator and normalization of their CA-125, determined to be a CR.
Patients must have stabilized or recovered (to Grade 1 or baseline) from all prior therapy-related toxicities (except alopecia).
Patients must have completed any major surgery at least 4 weeks before the first dose of maintenance treatment and have recovered or stabilized from the side effects of prior surgery before the first dose of maintenance treatment on study.

Patients must have adequate hematologic, liver, and kidney functions defined as follows:

Absolute neutrophil count (ANC) ≥ 1.5 × 109/L (1500/μL) without granulocyte colony-stimulating factor in the prior 10 days or long-acting white blood cell (WBC) growth factors in the prior 10 days of C1D1 of maintenance treatment.
Platelet count ≥ 100 × 109/L (100,000/μL) without platelet transfusion in the prior 10 days of C1D1 of maintenance treatment
Hemoglobin ≥ 9.0 g/dL without packed red blood cell (PRBC) transfusion in the prior 10 days of C1D1 of maintenance treatment
Serum creatinine ≤ 1.5 × upper limit of normal (ULN)
Aspartate aminotransferase and alanine aminotransferase ≤ 3.0 × ULN
Serum bilirubin ≤ 1.5 × ULN (patients with documented diagnosis of Gilbert syndrome are eligible if total bilirubin < 3.0 × ULN)
Serum albumin ≥ 2 g/dL Note: For Run-In patients, these criteria must be met before initiation of triplet therapy and before start of maintenance therapy.
Patients must be willing and able to sign the informed consent form (ICF) and to adhere to the protocol requirements.
Females of childbearing potential (FCBP) must agree to use highly effective contraceptive method(s) (as defined in Section 5.10.7) while on study medication and for at least 3 months after the last dose.
FCBP must have a negative pregnancy test within 4 days before the first dose of maintenance therapy.

Exclusion Criteria:

Patients with endometrioid, clear cell, mucinous, or sarcomatous histology; mixed tumors containing any of the above histologies; or low-grade/borderline ovarian tumor

More than one line of prior chemotherapy. Lines of prior anticancer therapy are counted with the following considerations:

Neoadjuvant ± adjuvant therapies are considered 1 line of therapy if the neoadjuvant and adjuvant correspond to 1 fully predefined regimen; otherwise, they are counted as 2 prior regimens.
Maintenance therapy (eg, bevacizumab, PARPi) will be considered part of the preceding line of therapy (ie, not counted independently).
