Inspyr Therapeutics (formerly GenSpera) developed mipsagargin (previously known as G-202), as a novel thapsigargin-based targeted prodrug that is activated by prostate-specific membrane antigen (PSMA)-mediated cleavage of an inert masking peptide. The active moiety is an inhibitor of the sarcoplasmic/endoplasmic reticulum calcium adenosine triphosphatase (SERCA) pump protein that is necessary for cellular viability. Mipsagargin was granted Orphan Drug designation by the U.S. Food and Drug Administration (FDA) in 2013 for evaluation in patients with hepatocellular carcinoma. In addition, mipsagargin has been studied in phase 2 clinical trial in patients with recurrent or progressive glioblastoma, in patients with clear cell renal cell carcinoma that expresses PSMA. Mipsagargin is expected to be launched on the market in the coming years.
