A new study identified an adenovirus gene therapy vector carrying a VEGF isoform. It can improve uterine blood flow in placental insufficiency, as reported in the peer-reviewed journal Human Gene Therapy.
Reduced uterine blood flow and lack of bioavailable VEGF due to placental insufficiency is a major cause of severe fetal growth restriction (FGR). This is untreatable and causes serious neonatal morbidity and death.
Anna David, UCL Institute for Women’s Health, and colleagues tested different VEGF isoforms on endothelial cells from four species, including from human umbilical vein. The results support the use of the best performing VEGF isoform “in a human clinical trial for FGR caused by placental insufficiency.”
