Tisotumab vedotin

Tisotumab vedotin Overview

Tisotumab vedotin is a specialized medication utilized in clinical oncology to treat specific forms of cancer in adults. It is a tissue factor directed antibody drug conjugate. The complex biological structure is comprised of an anti tissue factor human immunoglobulin G1 kappa antibody. This specific antibody is conjugated to monomethyl auristatin E, which acts as a powerful microtubule disrupting agent, utilizing a protease cleavable valine citrulline linker. Each monoclonal antibody molecule carries an average of four monomethyl auristatin E molecules. It serves as a targeted palliative and immunosuppressive therapy for advanced malignancies.

What Is Tisotumab vedotin & How Does It Work?

Tisotumab vedotin operates as a targeted tissue factor binder and transporter. Tissue factor is a primary initiator of the extrinsic blood coagulation cascade and plays a key role in tumor associated angiogenesis, progression, and metastasis for tumor survival. This factor is a novel target for cancers, as it is frequently overexpressed on solid tumors, notably including cervical cancer, and is directly associated with poor clinical outcomes.

Is Tisotumab vedotin FDA Approved?

The United States Food and Drug Administration originally granted accelerated approval to Tisotumab vedotin on September 20, 2021. This initial approval was specifically for the treatment of recurrent or metastatic cervical cancer in adults in whom the disease progressed during or after standard chemotherapy. Subsequently, on April 29, 2024, the medication was granted full FDA approval. It stands as the first and only approved antibody drug conjugate for this therapeutic indication.
