The first member of a new class of osteoporosis drugs reduced spinal fractures by about two-thirds in post-menopausal women and in men undergoing hormone-deprivation therapy for prostate cancer, according to two studies released online Tuesday. The drug, called denosumab, blocks production of cells called osteoclasts that break down bones, and physicians have high hopes for it because of its efficacy, ease of administration and apparent lack of severe side effects. But it’s a biological agent rather than a chemical, meaning it’s difficult to produce, and it is likely to be the highest-priced osteoporosis drug in an already-crowded marketplace. – From LA Times
