Denosumab Phase-3 Scorecard

[The trial in the limelight today is in the second row of the table.]


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 spanning numerous indications (although
some of them 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 three main
groups: metastatic cancer, non-metastatic cancer, and post-
menopausal osteoporosis.
