Genmab and Seagen Announce U.S. FDA Filing Acceptance for Priority Review of Tisotumab Vedotin Biologics License Application for Patients with Recurrent or Metastatic Cervical Cancer

Company Announcement

• FDA action date is Oct 10, 2021
• BLA submission supported by positive pivotal innovaTV 204 trial results presented at the European Society of Medical Oncology Virtual Congress 2020

COPENHAGEN, Denmark and BOTHELL, Wash.; April 09, 2021 – Genmab A/S (Nasdaq: GMAB) and Seagen Inc. (Nasdaq: SGEN) today announced that the U.S. Food and Drug Administration (FDA) has accepted for Priority Review the Biologics License Application (BLA) seeking accelerated approval for tisotumab vedotin. This BLA requests FDA approval of tisotumab vedotin for the treatment of patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. Under the Prescription Drug User Fee Act (PDUFA), the FDA has set a target action date of Oct 10, 2021. Tisotumab vedotin is an investigational antibody-drug conjugate (ADC) directed to tissue factor (TF), a cell-surface protein expressed on multiple solid tumors including cervical cancer, and is associated with tumor growth, angiogenesis, metastasis and poor prognosis.¹

“We are pleased that the tisotumab vedotin BLA has been accepted with Priority Review by the FDA as there is an unmet need for effective therapies for women with recurrent or metastatic cervical cancer, who have disease progression on or after chemotherapy,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab. “This is an important milestone for Genmab as it brings us closer to our goal of bringing differentiated therapies to patients and transforming cancer treatment.”

The FDA’s filing of the tisotumab vedotin BLA with Priority Review marks an important step forward for this ADC as a potential treatment for patients with recurrent or metastatic cervical cancer,” said Roger Dansey, M.D., Chief Medical Officer at Seagen. “We are collaborating closely with the FDA throughout the review process to make this important therapy available to patients.”

The BLA for tisotumab vedotin was submitted in February 2021. The submission is based on the results of the innovaTV 204 pivotal phase 2 single-arm clinical trial evaluating tisotumab vedotin as monotherapy in patients with previously treated recurrent or metastatic cervical cancer. These data were presented at the European Society for Medical Oncology (ESMO) Virtual Congress 2020.

About Cervical Cancer
Cervical cancer originates in the cells lining the cervix. Over 13,500 women are expected to be diagnosed with invasive cervical cancer in the U.S. in 2020, with approximately 4,200 deaths.² Cervical cancer remains one of the leading causes of cancer death in women globally, with over 311,000 women dying annually; the vast majority of these women being in the developing world.³ Routine medical examinations and human papillomavirus (HPV) vaccines have lowered the incidence of cervical cancer in the developed world. Despite these advances, women are still diagnosed with cervical cancer, which often recurs or becomes metastatic. Current therapies for previously treated recurrent or metastatic cervical cancer generally result in limited objective response rates of typically less than 15 percent with median overall survival ranging from 6.0 to 9.4 months.^4-10
