Purpose: Tisotumab vedotin-tftv, an antibody-drug conjugate, was recently FDA-approved for metastatic or treatment-resistant cervical cancer. A high rate of ocular comorbidities was seen in pivotal clinical trials. We present a case of a 46-year-old woman who experienced prolonged ocular surface adverse effects associated with use of the drug.
Observations: Our patient was initiated on tri-weekly 2mg/kg infusions of tisotumab for metastatic cervical cancer. Baseline ophthalmic exam was unremarkable. One week after the second infusion, she developed bilateral eyelid edema and chalazia managed with initiation of lid hygiene measures. Preceding the fourth infusion, she developed unilateral pseudomembranous conjunctivitis and bilateral meibomitis that improved with topical corticosteroids. The fifth infusion was subsequently given at a reduced dosage. Despite this, she experienced decreased vision, bilateral diffuse punctate epitheliopathy, and subepithelial haze. The patient was subsequently referred to the cornea service. Symptomatic and clinical improvement was initially achieved with the addition of bandage contact lenses (BCLs). As the keratitis improved, topical steroids were tapered and BCLs removed. She is currently maintained on a regimen that includes eyelid hygiene, preservative-free artificial tears, punctal plugs, autologous serum tears, and lifitegrast. Given the severity of the ophthalmic adverse effects, however, further tisotumab infusions were held.
Conclusions and importance: This is a report of a patient with prolonged ocular surface disease following the initiation of tisotumab, significant enough to lead to discontinuation. Antibody-drug conjugates are an emerging class of therapeutics across oncology, and ophthalmologists should be aware of their potential effects on ocular health.
