People suffering from osteoporosis experience severe weakening and thinning of bones.
Prolia currently has U.S. approval to treat postmenopausal women with osteoporosis at high risk for fracture. The drug brought in sales of $120 million to Amgen between April and June, up 36 percent sequentially.
According to the National Osteoporosis Foundation, two million men in the U.S. have osteoporosis and another 12 million are at risk, Amgen said in a statement.
