Amgen and UCB announce positive results from Phase 3 study evaluating Romosozumab in men with Osteoporosis
Amgen and UCB announced positive top-line results for romosozumab from the pivotal Phase 3 placeBo-contRolled study evaluatIng the efficacy anD safety of romosozumab in treatinG mEn with osteoporosis (BRIDGE). These data showed the BRIDGE study met the primary endpoint, demonstrating a statistically significant increase in bone mineral density (BMD) at the lumbar spine (as assessed by dual energy x-ray absorptiometry) in men with osteoporosis treated with romosozumab compared with placebo at 12 months.

All secondary endpoints comparing romosozumab with placebo were also met. Patients receiving romosozumab experienced a statistically significant increase in BMD at the femoral neck and total hip at 12 months and a statistically significant increase in BMD at the lumbar spine, femoral neck, and total hip at six months, compared with those receiving placebo.
In the BRIDGE study, a total of 245 men were randomized 2:1 to receive either 210 mg romosozumab subcutaneous (SC) every month (QM) or matched placebo SC QM for the duration of the 12-month treatment period.
