Transgenex Nanobiotech


Curing cancer with customized tests since 2012


Our technology targets the costly battery of cancer drug regimens causing patients to suffer side effects and at times catalyzing the growth of drug-resistant tumors. At TGN we individually assess each patient's tumor by creating the tumor outside the body, testing it with drugs and determining the most effective drug for the patient's treatment.
