Denosumab Phase-3 Scorecard

[New completion date for HRPC trial in prevention of bone
mets (from disclosures at AMGN’s ASCO webcast on 6/7/10).]


The phase-3 denosumab program is one of the largest ever conducted
for any drug by any company. All told, there are 22 phase-3 trials
(although some are open-label extension trials to assess long-term
safety that are effectively phase-4’s). The following table includes the
most consequential phase-3 trials; they fall into four main groups:
metastatic cancer/treatment of bone mets; metastatic cancer/prevention
of bone mets; preservation of bone health in non-metastatic cancer; and
postmenopausal osteoporosis.
