- None.
Company Announcement
- Phase 3 innovaTV 301 confirmatory trial met its primary endpoint of improved overall survival (OS) at predetermined, independent interim analysis
- Trial results to be submitted for presentation at a future medical meeting
- Genmab and Seagen to engage in discussions with regulatory authorities
The results of innovaTV 301/ENGOT cx-12/GOG 3057, a global, randomized, open-label Phase 3 trial, add to the previous results of innovaTV 204, which served as the basis for the accelerated approval of TIVDAK in
“TIVDAK is the only
“With limited options for advanced cervical cancer patients who have progressed after front-line therapy, there is a need for therapeutic options with new mechanisms of action, particularly those with a demonstrated survival benefit,” said Jan van de Winkel, Ph.D., Chief Executive Officer, Genmab. “These results provide hope for patients with recurrent or metastatic cervical cancer.”
Results of the Phase 3 innovaTV 301 clinical trial will be submitted for presentation at an upcoming medical congress and discussed with regulatory authorities.
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
About the innovaTV 301 Trial
The innovaTV 301 trial (NCT04697628) is a global, randomized, open-label Phase 3 trial evaluating TIVDAK® (tisotumab vedotin-tftv) 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 a standard of care systemic chemotherapy doublet or platinum-based therapy (if eligible) are included. The main efficacy outcome measure is overall survival. The main secondary outcomes are progression-free survival, 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 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 TIVDAK® (tisotumab vedotin)
TIVDAK® (tisotumab vedotin) is an antibody-drug conjugate (ADC) composed of Genmab’s human monoclonal antibody directed to tissue factor (TF) and Seagen’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 TIVDAK 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, TIVDAK also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity.

Important Safety Information
BOXED WARNING: OCULAR TOXICITY
TIVDAK caused changes in the corneal epithelium and conjunctiva resulting in changes in vision, including severe vision loss, and corneal ulceration. Conduct an ophthalmic exam at baseline, prior to each dose, and as clinically indicated. Adhere to premedication and required eye care before, during, and after infusion. Withhold TIVDAK until improvement and resume, reduce the dose, or permanently discontinue, based on severity.
WARNINGS AND PRECAUTIONS
Ocular adverse reactions occurred in
In innovaTV 204,
Refer patients to an eye care provider for an ophthalmic exam, including visual acuity and slit lamp exam, at baseline, prior to each dose, and as clinically indicated. Adhere to premedication and required eye care to reduce the risk of ocular adverse reactions. Promptly refer patients to an eye care provider for any new or worsening ocular signs and symptoms. Withhold dose, reduce the dose, or permanently discontinue TIVDAK based on the severity of the adverse reaction.
Peripheral Neuropathy (PN) occurred in
Hemorrhage occurred in
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 (
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
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.
Embryo-fetal toxicity: TIVDAK can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TIVDAK and for 2 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with TIVDAK and for 4 months after the last dose.
Adverse Reactions
Serious adverse reactions occurred in
Adverse reactions leading to permanent discontinuation occurred in
The most common (≥
Drug Interactions
Strong CYP3A4 inhibitors: Concomitant use with strong CYP3A4 inhibitors may increase unconjugated monomethyl auristatin E (MMAE) exposure, which may increase the risk of TIVDAK adverse reactions. Closely monitor patients for TIVDAK adverse reactions.
Use in Specific Populations
Moderate or severe hepatic impairment: MMAE exposure and adverse reactions are increased. Avoid use.
Lactation: Advise lactating women not to breastfeed during TIVDAK treatment and for at least 3 weeks after the last dose.
