Tisotumab vedotin 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 tisotumab vedotin until improvement and resume, reduce the dose, or permanently discontinue, based on severity.
Cervical cancer, recurrent or metastatic: IV: 2 mg/kg (maximum dose: 200 mg for patients ≥100 kg) once every 3 weeks until disease progression or unacceptable toxicity (Ref).
Ophthalmic care and premedication:
Topical corticosteroid ophthalmic drops: Initial prescription (and all renewals) for any corticosteroid should be made only after ophthalmic examination with a slit lamp. Administer the first drop in each eye prior to each tisotumab vedotin infusion. Instruct patients to continue eye drop administration in each eye as prescribed for 72 hours after each tisotumab vedotin infusion.
Topical vasoconstrictor ophthalmic drops: Administer in each eye immediately prior to each tisotumab vedotin infusion.
Cooling packs: Use cooling eye packs during each tisotumab vedotin infusion.
Topical lubricating ophthalmic drops: Instruct patients to administer during tisotumab vedotin treatment and for 30 days after the last tisotumab vedotin dose.
Contact lens: Patients should avoid wearing contact lens (unless advised by their eye care provider) for the duration of tisotumab vedotin treatment.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Concerns related to adverse effects:
• Dermatologic toxicity: Severe cutaneous adverse reactions, including Stevens Johnson syndrome (which may be life-threatening or fatal) may occur. Signs/symptoms of severe cutaneous adverse reactions include target lesions, worsening skin reactions, skin blistering/peeling, painful sores in the mouth, nose, throat, or genital area, fever/flu-like symptoms, and/or swollen lymph nodes.
• Hemorrhage: Hemorrhage commonly occurred in patients with cervical cancer who received tisotumab vedotin. The most common hemorrhagic adverse reactions (all grades) were epistaxis, hematuria, and vaginal hemorrhage. Grade 3 hemorrhage occurred in a small percentage of patients. The median time to onset of hemorrhage was 0.3 months (range: up to 6.5 months). Of the patients who experienced hemorrhage, a majority had complete resolution and some experienced partial resolution (defined as a decrease in severity by one or more grades from the worst grade) at last follow-up.
• Ocular toxicity: Ocular adverse reactions occurred in over half of patients with cervical cancer who were treated with tisotumab vedotin. The most common ocular adverse reactions were conjunctival adverse reactions, dry eye, corneal adverse reactions, and blepharitis. Grade 3 ocular adverse reactions (including severe ulcerative keratitis) occurred in a small percentage of patients. A case of ulcerative keratitis with perforation requiring corneal transplantation was reported and cases of symblepharon have been reported. The median time to onset of the first ocular adverse reaction was 1.2 months (range: up to 6.5 months). Of the patients who experienced ocular events, over half experienced complete resolution and nearly one-third experienced partial improvement (defined as a decrease in severity by one or more grades from the worst grade) at last follow-up. Visual acuity changes to 20/50 or worse have been reported in a small number of patients, including rare visual acuity changes to 20/200. Of the patients who experienced decreased visual acuity to 20/50 or worse, a majority of cases resolved.
• Peripheral neuropathy: Peripheral neuropathy occurred in almost half of patients with cervical cancer who received tisotumab vedotin; grade 3 peripheral neuropathy was reported. Peripheral neuropathy adverse reactions included peripheral neuropathy, peripheral sensory neuropathy, peripheral sensorimotor neuropathy, motor neuropathy, muscular weakness, and demyelinating peripheral polyneuropathy. A case of Guillain-Barre syndrome developed in a patient with a different tumor type (not cervical cancer) who received tisotumab vedotin at the recommended dose. The median time to onset of peripheral neuropathy was 2.4 months (range: up to ~11 months). Of the patients who developed peripheral neuropathy, some patients experienced complete resolution or partial improvement (defined as a decrease in severity by one or more grades from the worst grade) at last follow-up.
• Pulmonary toxicity: Severe, life-threatening, or fatal pneumonitis can occur in patients treated with antibody drug conjugates containing vedotin, including tisotumab vedotin. Among patients with cervical cancer treated who received tisotumab vedotin, a small percentage experienced pneumonitis, including a fatal case. Pulmonary symptoms indicative of pneumonitis may include hypoxia, cough, dyspnea, or interstitial infiltrates on radiologic exams.
Special populations:
• Older age: Patients ≥65 years of age experienced a higher incidence of grade 3 and higher and serious adverse reactions (compared to patients <65 years of age).

Verify pregnancy status prior to treatment initiation (in patients who could become pregnant). Monitor patients for signs/symptoms of hemorrhage, neuropathy (eg, paresthesia, tingling or a burning sensation, neuropathic pain, muscle weakness, or dysesthesia), ocular toxicity, cutaneous adverse reactions (including Stevens-Johnson syndrome and/or target lesions, worsening skin reactions, skin blistering/peeling, painful sores in the mouth, nose, throat, or genital area, fever/flu-like symptoms, and/or swollen lymph nodes), and for pulmonary symptoms indicative of pneumonitis (eg, hypoxia, cough, dyspnea, or interstitial infiltrates on radiologic exams); exclude infectious, neoplastic, and other causes for pulmonary symptoms via appropriate investigations.
The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.
Tisotumab vedotin is a tissue factor (TF)-directed antibody drug conjugate (ADC) comprised of an anti-TF IgG1-kappa antibody conjugated to the microtubule-disrupting agent monomethyl auristatin E (MMAE), via a protease-cleavable valine-citrulline linker. The antibody is directed against cell surface TF, which is the primary initiator of the extrinsic blood coagulation cascade. Tisotumab vedotin’s anticancer activity is likely due to the ADC binding 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 apoptosis. Tisotumab vedotin also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity.
Duration: Median duration of response: 8.3 months.
Distribution: Tisotumab vedotin: Vdss: 7.83 L.
Protein binding: Microtubule-disrupting agent monomethyl auristatin E (MMAE): 68% to 82%.
Metabolism: Tisotumab vedotin is expected to undergo catabolism to small peptides, amino acids, unconjugated MMAE, and unconjugated MMAE-related metabolites; tisotumab vedotin releases unconjugated MMAE via proteolytic cleavage, and unconjugated MMAE is primarily metabolized via CYP3A4.
Half-life elimination: Tisotumab vedotin: ~4 days; unconjugated MMAE: ~2.5 days.
Time to peak: Tisotumab vedotin: Near the end of the infusion; unconjugated MMAE: 2 to 3 days after the tisotumab vedotin dose.
Excretion: Clearance: Tisotumab vedotin: 1.54 L/day; unconjugated MMAE: ~46 L/day.
Hepatic function impairment: Although there were no clinically significant differences in tisotumab vedotin exposure, unconjugated microtubule-disrupting agent monomethyl auristatin E exposures were 37% higher in patients with mild hepatic impairment (bilirubin 1 to 1.5 times ULN and AST < ULN or bilirubin ≤ ULN and AST > ULN, compared to patients with normal hepatic function.
