Background

Apatorsen is a second generation antisense drug which in preclinical experiments, inhibits production of Heat Shock Protein 27 (Hsp27) a cell survival protein found at elevated levels in many human cancers including prostate, lung, breast, ovarian, bladder, renal, pancreatic, multiple myeloma and liver cancer.
