Patient-Reported Outcomes with Mirvetuximab Versus Chemotherapy in FORWARD I Study Reinforces Differentiated Tolerability Profile
"The data presented at ESMO continue to support mirvetuximab's potential to displace single-agent chemotherapy in FRα-positive ovarian cancer and will serve as a guide as we seek to advance the broader development program," said
ANALYSES OF PATIENT-REPORTED OUTCOMES WITH MIRVETUXIMAB SORAVTANSINE VERSUS STANDARD CHEMOTHERAPY IN THE RANDOMIZED PHASE 3 FORWARD I STUDY IN OVARIAN CANCER (GOG 3011)

Poster: #532P
The Phase 3 FORWARD I trial enrolled 366 patients who were randomized 2:1 to receive either mirvetuximab or the physician's choice of single-agent chemotherapy (pegylated liposomal doxorubicin, topotecan, or weekly paclitaxel). Eligible patients were diagnosed with platinum-resistant ovarian cancer that expresses medium or high levels of FRα and were treated with up to three prior regimens. The primary endpoint was progression-free survival (PFS), which was assessed in the entire study population and in the subset of patients with high FRα expression. Patients completed PRO assessments during screening, on day 1 of cycle 1, every 9 weeks thereafter (±1 week) until disease progression, and at the end of treatment visit.
Key findings:
"An unmet need remains for safe, effective, and well-tolerated therapeutic options for patients with platinum-resistant ovarian cancer, despite treatment advancements seen in this setting," said
