ImmunoGen Provides Regulatory Update on Mirvetuximab Soravtansine Monotherapy in Ovarian Cancer
Conference Call to be Held at
ImmunoGen requested the meeting to discuss the results of the Phase 3
FORWARD I trial and a potential path to registration for mirvetuximab
monotherapy. The agency advised that, because FORWARD I did not meet its
primary endpoint under the pre-specified statistical analysis plan, the
data generated assessing the secondary endpoints from the study could
not be used to support an application for accelerated approval.
“We are encouraged by the consistent signal of anti-tumor activity and
the favorable benefit-risk profile in patients with high FRα expression
in our Phase 3 FORWARD I trial,” said

ABOUT FORWARD I
FORWARD I is a Phase 3 trial in which 366 patients were randomized 2:1 to receive either mirvetuximab soravtansine 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 of this study was progression free survival (PFS), which was assessed in the entire study population and in the subset of patients with high FRα expression. ImmunoGen estimates that 12,000-14,000 patients per year in the U.S. meet these criteria, with a comparable number in the major markets in

ABOUT MIRVETUXIMAB SORAVTANSINE
Mirvetuximab soravtansine (IMGN853) is the first folate receptor alpha (FRα)-targeting ADC. It uses a humanized FRα-binding antibody to target the ADC specifically to FRα-expressing cancer cells and a potent anti-tumor agent, DM4, to kill the targeted cancer cells.
ImmunoGen is developing the next generation of antibody-drug conjugates (ADCs) to improve outcomes for cancer patients. By generating targeted therapies with enhanced anti-tumor activity and favorable tolerability profiles, we aim to disrupt the progression of cancer and offer our patients more good days. We call this our commitment to “target a better now.” The Company has built a productive platform generating a broad pipeline of ADCs targeting solid tumors and hematologic malignancies.
