Bone metastases in metastatic castration-resistant prostate cancer (mCRPC) can invade a range of sites in the skeleton where they precipitate a spectrum of pathological processes that increase morbidity, negatively affect quality of life, and decrease survival.

The latest results from an open-label, phase Ib study of the STAT3 inhibitor BBI-608 (napabucasin) with a standard chemotherapy (FOLFIRI with or without bevacizumab) in the treatment of advanced colorectal cancer, have been presented at the ASCO 2016 Gastrointestinal Symposium. Evidence of antitumor activity and a favorable safety profile were seen in phase I studies.

Researchers note that chronic Hedgehog (Hh) pathway stimulation has been shown in prostate, lung, and ovarian cancers, and that zinc levels decrease early in prostate cancer continuing to castration-resistant disease. Researchers are exploring whether or not zinc may suppress the autocatalysis in the Hh precursor and inhibit production of biologically active Hh ligand.
