A Review of Tisotumab Vedotin-tftv in Recurrent or Metastatic Cervical Cancer

Abstract

Objective: To evaluate the safety and efficacy of tisotumab vedotin-tftv (TV), a first-in-class vectorized anti-tissue factor (TF) antibody-drug conjugate (ADC), for the treatment of recurrent or metastatic cervical cancer. Data Sources: A literature search of ClinicalTrials.gov, Embase, and PubMed was conducted using the terms tisotumab vedotin AND cervical cancer from inception to June 30, 2022. Study Selection and Data Extraction: All applicable publications, package inserts, meeting abstracts, and clinical trials involving TV in the treatment of cervical cancer were reviewed. Data Synthesis: TV is a fully human TF-specific monoclonal antibody conjugated to monomethyl auristatin E, which serves as a highly potent cytotoxic payload. In the pivotal phase II InnovaTV 204 clinical trial, TV demonstrated an objective response rate of 24% (95% confidence interval [CI], 16%-33%). The mean duration of response was 8.3 months. Common toxicities included abdominal pain, alopecia, conjunctivitis, constipation, decreased appetite, diarrhea, dry eye, epistaxis, nausea/vomiting, and peripheral neuropathy. Unique and/or serious adverse events warranting careful monitoring include ocular complications, hemorrhaging, peripheral neuropathies, fetal-embryo toxicity, pneumonitis, and immunogenicity. Relevance to Patient Care and Clinical Practice: Recurrent or metastatic cervical cancer remains a high-risk disease with limited treatment options. Using ADCs to target tumors with aberrant expression of TF appears to be a viable treatment strategy. Conclusions: TV is the first Food and Drug Administration–approved TF-directed ADC. With a manageable safety profile and promising anticancer activity, TV warrants consideration as a novel targeted agent for the treatment of recurrent or metastatic cervical cancer. Further studies are required to determine the optimal place in therapy for TV.
