TIVDAK® Supplemental Biologics License Application Accepted for Priority Review by FDA for Patients with Recurrent or Metastatic Cervical Cancer

 Pfizer Inc. (NYSE: PFE) and Genmab A/S (Nasdaq: GMAB) announced today that the U.S. Food and Drug Administration (FDA) has accepted the supplemental Biologics License Application (sBLA) seeking to convert the accelerated approval of TIVDAK® (tisotumab vedotin-tftv) to full approval, for the treatment of patients with recurrent or metastatic cervical cancer with disease progression on or after first-line therapy. The application has been granted Priority Review with a Prescription Drug User Fee Act (PDUFA) goal date of May 9, 2024.

“The Phase 3 innovaTV 301 trial demonstrated a favorable benefit/risk profile, including improvement in overall survival, and adds to the overall data supporting TIVDAK as a treatment option for people with recurrent and metastatic cervical cancer who have limited treatment options,” said Roger Dansey, M.D., Chief Development Officer, Oncology at Pfizer. “The FDA acceptance of our sBLA for review is important progress toward continuing to offer an option that can extend the lives of more adults with cervical cancer.”

The sBLA is supported by efficacy and safety data from the global, randomized, Phase 3 innovaTV 301 trial (NCT04697628), in which TIVDAK demonstrated superior overall survival (OS), progression-free survival (PFS) and confirmed objective response rate (ORR), as assessed by the investigator, in patients with previously treated recurrent or metastatic cervical cancer compared to chemotherapy. The safety profile of TIVDAK in innovaTV 301 was consistent with its known safety profile as presented in the U.S. prescribing information. In October 2023, results from the innovaTV 301 study were presented during a Presidential Symposium at the European Society of Medical Oncology (ESMO) Congress.

The U.S. Prescribing Information for TIVDAK includes a BOXED WARNING for Ocular Toxicity as well as the following Warnings and Precautions: peripheral neuropathy, hemorrhage, pneumonitis, severe cutaneous adverse reactions, and embryo-fetal toxicity. Please see below for additional Important Safety Information.

“Therapeutic options for metastatic cervical cancer that not only demonstrate a survival advantage but also include a novel approach to treating this condition are needed,” said Jan van de Winkel, Ph.D., Chief Executive Officer at Genmab. “This milestone underscores our commitment to continuing to deliver TIVDAK as a treatment option to women in the U.S. diagnosed with cervical cancer whose disease has progressed after first-line treatment.”

TIVDAK was granted accelerated approval in the U.S. by the FDA in September 2021. The accelerated approval is based on tumor response and durability of response from the innovaTV 204 pivotal Phase 2 single-arm clinical trial evaluating TIVDAK as monotherapy in patients with previously treated recurrent or metastatic cervical cancer. The data from innovaTV 301 will support global regulatory submissions.

About Cervical Cancer 
Cervical cancer remains a disease with high unmet need despite advances in effective vaccination and screening practices to prevent and diagnose pre-/early-stage cancers for curative treatment. Recurrent and/or metastatic cervical cancer is a particularly devastating and mostly incurable disease; up to 15 percent of adults with cervical cancer are diagnosed with metastatic disease at diagnosis1,2 and, for adults diagnosed at earlier stages who receive treatment, up to 31.5 percent will experience disease recurrence.3 It was estimated that, in 2023, more than 13,960 new cases of invasive cervical cancer were diagnosed in the U.S. and 4,310 adults would die from the disease.4

About the innovaTV 301 Trial 
The innovaTV 301 trial (NCT04697628) is a global, 1:1 randomized, open-label Phase 3 trial evaluating (tisotumab vedotin-tftv) versus investigator’s choice of chemotherapy alone (topotecan, vinorelbine, gemcitabine, irinotecan, or pemetrexed) in 502 randomized patients with recurrent or metastatic cervical cancer who received one or two prior systemic regimens in the recurrent or metastatic setting.

Patients with recurrent or metastatic cervical cancer with squamous cell, adenocarcinoma, or adenosquamous histology, and disease progression during or after treatment with chemotherapy doublet +/- bevacizumab and an anti-PD-(L)1 agent (if eligible) are included. The primary endpoint is overall survival. The main secondary outcomes are progression-free survival, confirmed objective response rate, time to response, and duration of response, as assessed by the investigator, as well as safety and quality of life outcomes.

The study was conducted by Seagen, recently acquired by Pfizer, in collaboration with Genmab, European Network of Gynaecological Oncological Trial Groups (ENGOT, study number ENGOT cx-12) and the Gynecologic Oncology Group (GOG) Foundation (study number GOG 3057), as well as other global gynecological oncology cooperative groups.
