Acronym:
VARTUTRACE
Brief Summary:
VARTUTRACE is a first-in-human PETCT molecular imaging study in patients with solid tumors This study will investigate the biodistribution and pharmacology of two antibody fragments binding oncofetal Chondroitin Sulfate CS
Oncofetal CS are tumor-specific carbohydrate motifs present in proteoglycans and identified by VAR2 Pharmaceuticals as expressed during fetal development Oncofetal CS reappears in the vast majority of cancers while remaining largely absent from normal tissues
VAR2 Pharmaceuticals recently developed antibodies specific for oncofetal CS VARTUTRACE uses two of these as radiolabeled antibody fragments to study biodistribution tumor accumulation pharmacodynamics and clearance pathways in a diverse patient population

Detailed Description:
VARTUTRACE aims to investigate the biodistribution and pharmacology in patients with solid tumors of two antibody fragments specific for oncofetal CS
VAR2 Pharmaceuticals has identified and characterized oncofetal CS as a group of tumor-specific carbohydrate motifs that appear in placental tissue during fetal development and in most cancers while remaining largely absent from healthy tissue VAR2 Pharmaceuticals recently developed a panel of antibodies specific for oncofetal CS and characterized their tumor specificity therapeutic and safety in pre-clinical models under various formats
VARTUTRACE is a Phase 0 microdosing study of a single administration of lt30 nmol of one of the two most promising antibody fragments identified by VAR2 Pharmaceuticals - C9 and F8 Both antibody fragments will be used as short chain variable fragments scFvs labelled with the radioisotope Zirconium-89 89Zr and are therefore respectively named 89Zr-C9scFv or 89Zr-F8scFv As it remains unclear from the pre-clinical in vitro and in vivo data which of the two will have the most optimal tumor targeting properties in patients with solid tumors both scFvs will be evaluated
The biodistribution pharmacokinetics pharmacodynamics and clearance of two of these antibody fragments is planned to be studied in up to 32 patients with various cancers ie a basket-trial
