Description
PRINCIPLE OF THE ASSAY This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant Human CD142 has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Tisotumab in the sample competitively binds to the pre-coated protein with biotin-labeled Tisotumab. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Tisotumab bound in the initial step. The color development is stopped and the intensity of the color is measured.
Applications
Used for the quantitative determination of Tisotumab concentration in serum and plasma.

Background
Tisotumab vedotin, also known as HuMax-TF, HuMax®-TF-ADC or TF-011-MMAE, is an antibody-drug conjugate (ADC) targeted to tissue factor (TF), a protein involved in tumor signaling and angiogenesis. Tisotumab vedotin includes an antibody targeting TF conjugated with monomethyl auristatin E (MMAE) via a cleavable maleimidocaproyl-valyl-citrullinyl-p-aminobenzyloxycarbonyl (mc-val-cit-PABC) type linker. Based on its high expression on many solid tumors (including ovarian, prostate, bladder, esophageal, endometrial and lung) and its rapid internalization, TF is considered a suitable target for antibody-drug conjugates. In pre-clinical trials tisotumab vedotin has shown strong ability to bind to TF and inhibit tumor growth. Genmab and Seattle Genetics are jointly developing tisotumab vedotin. In a Phase IIa study, preliminary data demonstrated a manageable safety profile and encouraging efficacy (ORR 37%) in relapsed, recurrent or metastatic cervical cancer.
