Genmab and Seagen Present Data from Tisotumab Vedotin (TIVDAK®) Clinical Development Program and Additional Cervical Cancer Research at ASCO 2022 Annual Meeting
-- Interim results of tisotumab vedotin plus pembrolizumab from Phase 1b/2 innovaTV 205 trial, showing

“These data showed encouraging and durable anti-tumor activity and provide rationale for the continued development of tisotumab vedotin (TV) in front-line recurrent or metastatic cervical cancer, including its potential use as part of triplet or quadruplet combination therapy,” said
Dose expansion Cohort E enrolled 33 patients with recurrent or metastatic cervical cancer who had not received any prior systemic therapy. At the time of data cutoff, the confirmed ORR among 32 evaluable patients was

In Cohort E, the most common treatment-emergent adverse events (TEAEs) were alopecia (
Tisotumab vedotin in combination with pembrolizumab across lines of treatment (Cohorts E/F), and with carboplatin (Cohort D) in first-line, demonstrated a tolerable and manageable safety profile. Across all three cohorts, no new safety signals were reported outside of known adverse events associated with the individual agents.
Tisotumab vedotin is approved for treatment of patients with previously treated recurrent or metastatic cervical cancer in the US and is commercialized under the tradename TIVDAK. See TIVDAK
“With Genmab, we will continue to investigate tisotumab vedotin in combination with other therapies because there is still an unmet need for more effective first-line treatment for advanced cervical cancer patients,” said
One highlight of real-world studies presented is a poster discussion on the Cervical Cancer Geographical Burden Analyzer. This is an open access, web-based, interactive tool to visualize geographical areas in the US where cervical cancer education or healthcare resource needs are high.
“The Cervical Cancer Geographical Burden Analyzer has potential to help expand understanding of cervical cancer disease burden across different communities,” said
Additional updates from the tisotumab vedotin clinical development program were presented at the ASCO 2022 Annual Meeting, including trial-in-progress overviews for innovaTV 205/ENGOT-cx8/GOG-3024 evaluating first-line tisotumab vedotin in combination with pembrolizumab, carboplatin and bevacizumab in first-line r/mCC; and for innovaTV 207 Part D evaluating tisotumab vedotin in combination with pembrolizumab and platinum in squamous cell carcinoma of the head and neck (HNSCC) and squamous cell non-small cell lung cancer (sqNSCLC).
“The collective data presented for tisotumab vedotin at the ASCO 2022 Annual Meeting are reflective of our commitment to investigating this therapy across treatment lines and in combination with other therapies,” said
About the innovaTV 205 Trial
The innovaTV 205 trial (also known as ENGOT-cx8/GOG-3024) is a Phase 1b/2 open-label, multi-center trial of tisotumab vedotin monotherapy and in combination with bevacizumab, pembrolizumab, or carboplatin in patients with recurrent or metastatic cervical cancer. The study consists of two parts: dose escalation (Cohorts A, B, and C) and dose expansion (Cohorts D, E, F, G and H). Patients enrolled in the dose escalation cohorts have progressed during or after standard of care therapy or are intolerant or ineligible to receive standard of care treatments. The primary objective is to identify and establish the maximum tolerated dose and Recommended Phase 2 Dose (RP2D) of tisotumab vedotin as combination therapy. Within the dose expansion cohorts, patients with recurrent or metastatic cervical cancer who have not previously received prior systemic therapy are treated in Cohorts D, E and H, with patients who have progressed on or after standard of care treatments evaluated in Cohorts F and G.

About Tisotumab Vedotin
Tisotumab vedotin-tftv (TIVDAK®) 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. Nonclinical data suggests 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.
In
Indication
TIVDAK is indicated for the treatment of adult patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy.
This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.
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
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
Pneumonitis: Severe, life-threatening, or fatal pneumonitis 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. 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.
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
In the innovaTV 204 clinical trial (n=101), 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.
