Amgen announced positive top-line results from a pivotal Phase III head-to-head trial evaluating denosumab administered subcutaneously versus Zometa administered as an intravenous (IV) infusion in the treatment of bone metastases in 1,776 advanced cancer patients with solid tumors (not including breast and prostate cancer) or multiple myeloma.
Here's what Amgen had to say: "For the primary endpoint, patients treated with denosumab experienced a similar time to first skeletal-related event (SRE) (fracture, radiation to bone, surgery to bone, or spinal cord compression) compared with those receiving Zometa (hazard ratio 0.84, 95 percent CI: 0.71-0.98), which is statistically significant for non-inferiority (p<0.0007). Although numerically greater, the delay in the time to first SRE associated with denosumab treatment was not statistically superior compared to Zometa (adjusted p=0.06) (secondary endpoint). The time to first-and-subsequent SRE was also numerically greater but not statistically superior compared to Zometa (hazard ratio 0.90, 95 percent CI: 0.77-1.04) (secondary endpoint)." Incidence of adverse events and serious adverse events was consistent with what was previously reported for these two agents.
"We are extremely pleased with these results, which continue to demonstrate that inhibiting RANK Ligand with denosumab provides a clinically meaningful benefit for advanced cancer patients with solid tumors that have metastasized to the bone, and to patients with multiple myeloma, both groups who routinely suffer SREs," said Roger M. Perlmutter, M.D., Ph.D., executive vice president of R&D at Amgen. "We are very encouraged by the overall strength of the data, which we will present in a scientific forum later this year. We are also looking forward to reviewing the results of a final SRE study, in patients with advanced prostate cancer, next year."
Full safety and efficacy data will be submitted for presentation at an upcoming medical meeting in the second half of this year.
