Positive
  • None.
Negative
  • None.

The validation of the marketing authorization application for tisotumab vedotin by the EMA marks a significant advancement in the treatment landscape for recurrent or metastatic cervical cancer. As an oncologist, the potential approval of an antibody-drug conjugate (ADC) such as tisotumab vedotin is noteworthy, given that ADCs represent a targeted therapy approach, combining an antibody with a cytotoxic drug to specifically target and kill cancer cells, while sparing healthy tissue.

Considering the Phase 3 innovaTV 301 trial results, which indicate superior overall survival, progression-free survival and objective response rate compared to chemotherapy, this could translate into a meaningful clinical benefit for patients. The safety profile consistency with known data is also reassuring. Should this ADC be approved, it could potentially establish a new standard of care for this patient population, which currently has limited treatment options after systemic therapy failure.

From a research perspective, the inclusion of data from both the Phase 3 innovaTV 301 trial and the Phase 2 innovaTV 204 trial in the MAA underscores the robustness of the clinical evidence supporting tisotumab vedotin. The fact that this ADC has demonstrated efficacy in a randomized trial setting adds significant weight to its potential market approval.

The ADC's mechanism of action and its ability to deliver cytotoxic drugs directly to cancer cells could reduce systemic toxicity, a critical consideration in oncology therapeutics. Moreover, the confirmed objective response rate (ORR) is a key metric indicating the drug's efficacy in shrinking or eliminating tumors, which is a primary goal in the management of metastatic cancer.

For investors and stakeholders in the pharmaceutical industry, the EMA's validation of tisotumab vedotin's MAA could signal a potential upcoming shift in the market dynamics for cervical cancer treatments. Approval could lead to market penetration in the EU, complementing its existing U.S. approval under the brand name TIVDAK.

Given that cervical cancer is the fourth most common cancer in women worldwide, the commercial prospects for an effective treatment are significant. An approval would not only benefit patients but also potentially enhance the market value of Genmab and Pfizer. It is important to monitor the regulatory review process closely, as any updates will likely impact the companies' stock performance. The collaboration between Genmab and Pfizer also illustrates the strategic partnerships shaping the oncology sector, potentially leading to faster drug development and greater market reach.

  • Validation is supported by data from Phase 3 innovaTV 301 trial

COPENHAGEN, Denmark--(BUSINESS WIRE)-- Genmab A/S (Nasdaq: GMAB) and Pfizer, Inc. (NYSE PFE) today announced that the European Medicines Agency (EMA) has validated for review the marketing authorization application (MAA) of tisotumab vedotin, an antibody-drug conjugate (ADC), developed for the treatment of adult patients with recurrent or metastatic cervical cancer with disease progression on or after systemic therapy. If approved, tisotumab vedotin would be the first ADC granted European Union (EU) marketing authorization for people living with cervical cancer.

The MAA is based on data from the global, randomized, Phase 3 innovaTV 301 trial (NCT04697628), in which tisotumab vedotin demonstrated superior overall survival (OS), progression-free survival (PFS) and a confirmed objective response rate (ORR) in patients with previously treated recurrent or metastatic cervical cancer compared to chemotherapy. Data 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 was also included in the MAA. The safety profile of tisotumab vedotin in innovaTV 301 was consistent with its known safety profile as presented in the U.S. prescribing information.

“The validation of our application is an important milestone supporting our commitment to bringing a new therapeutic option for recurring or metastatic cervical cancer to more patients,” said Jan van de Winkel, Ph.D., Chief Executive Officer, Genmab. “There continues to be a need for therapeutic options for these patients, and we’re dedicated to delivering potential improved outcomes to women diagnosed with this devastating disease.”

“Today’s milestone signifies our progress in exploring the availability of tisotumab vedotin for more patients with recurrent or metastatic cervical cancer,” said Roger Dansey, M.D., Chief Development Officer, Oncology, Pfizer. “We remain dedicated to collaborating closely with regulatory authorities, while we navigate the process to potentially deliver a new therapeutic option to people facing this debilitating disease.”

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. It is the fourth leading cause of cancer death in women worldwide,i,ii with approximately 570,000 new cases diagnosed and 311,000 new deaths of women annually.iii,iv Recurrent and/or metastatic cervical cancer is a particularly devastating and mostly incurable disease; when diagnosed in later stages, less than 5 percent of these patients survive five years.v In the European Union specifically, cervical cancer ranks 11th among the most frequently occurring cancers in women and 12th among the most frequent causes of cancer death in them.vi

About the innovaTV 301 Trial

The innovaTV 301 trial (NCT04697628) is a global, randomized, open-label Phase 3 trial evaluating tisotumab vedotin versus investigator’s choice of chemotherapy alone (topotecan, vinorelbine, gemcitabine, irinotecan, or pemetrexed) in 502 patients with recurrent or metastatic cervical cancer who received no more than 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).

About Tisotumab Vedotin

Tisotumab vedotin is an antibody-drug conjugate (ADC) composed of Genmab’s human monoclonal antibody directed to tissue factor (TF) and Pfizer’s ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (MMAE) to the antibody. Determination of TF expression is not required. Nonclinical data suggest that the anticancer activity of tisotumab vedotin is due to the binding of the ADC to TF-expressing cancer cells, followed by internalization of the ADC-TF complex, and release of MMAE via proteolytic cleavage. MMAE disrupts the microtubule network of actively dividing cells, leading to cell cycle arrest and apoptotic cell death. In vitro, tisotumab vedotin also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity.

Tisotumab vedotin-tftv (Tivdak®) is approved in the U.S. under the accelerated approval program, and a supplemental Biologics License Application (sBLA) seeking to convert its accelerated approval to a full approval was granted Priority Review by the U.S. Food and Drug Administration (FDA). Use of tisotumab vedotin in recurrent or metastatic cervical cancer is not approved in the EU.

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.

PN adverse reactions included peripheral neuropathy (20%), peripheral sensory neuropathy (11%), peripheral sensorimotor neuropathy (5%), motor neuropathy (3%), muscular weakness (3%), and demyelinating peripheral polyneuropathy (1%). One patient with another tumor type treated with TIVDAK at the recommended dose developed Guillain-Barré syndrome.

Hemorrhage occurred in 62% of cervical cancer patients treated with TIVDAK across clinical trials. The most common all grade hemorrhage adverse reactions were epistaxis (44%), hematuria (10%), and vaginal hemorrhage (10%). Grade 3 hemorrhage occurred in 5% of patients.

Monitor patients for signs and symptoms of hemorrhage. For patients experiencing pulmonary or central nervous system (CNS) hemorrhage, permanently discontinue TIVDAK. For Grade ≥2 hemorrhage in any other location, withhold until bleeding has resolved, blood hemoglobin is stable, there is no bleeding diathesis that could increase the risk of continuing therapy, and there is no anatomical or pathologic condition that can increase the risk of hemorrhage recurrence. After resolution, either resume treatment or permanently discontinue TIVDAK.

Pneumonitis that is severe, life-threatening, or fatal can occur in patients treated with antibody-drug conjugates containing vedotin, including TIVDAK. Among patients with cervical cancer treated with TIVDAK across clinical trials, 2 patients (1.3%) experienced pneumonitis, including 1 patient who had a fatal outcome.

Monitor patients for pulmonary symptoms of pneumonitis. Symptoms may include hypoxia, cough, dyspnea or interstitial infiltrates on radiologic exams. Infectious, neoplastic, and other causes for symptoms should be excluded through appropriate investigations. Withhold TIVDAK for patients who develop persistent or recurrent Grade 2 pneumonitis and consider dose reduction. Permanently discontinue TIVDAK in all patients with Grade 3 or 4 pneumonitis.

Severe cutaneous adverse reactions, including events of fatal or life-threatening Stevens-Johnson syndrome (SJS), can occur in patients treated with TIVDAK.

Monitor patients for signs or symptoms of severe cutaneous adverse reactions, which include target lesions, worsening skin reactions, blistering or peeling of the skin, painful sores in mouth, nose, throat, or genital area, fever or flu-like symptoms, and swollen lymph nodes. If signs or symptoms of severe cutaneous adverse reactions occur, withhold TIVDAK until the etiology of the reaction has been determined. Early consultation with a specialist is recommended to ensure greater diagnostic accuracy and appropriate management. Permanently discontinue TIVDAK for confirmed Grade 3 or 4 severe cutaneous adverse reactions, including SJS.
