• The benefits of zoledronic acid, in combination with hormone therapy have been investigated<br />

in a study by Saad in men with HRPC and bone metastases. 124 This was a <strong>multi</strong>centre, randomised,<br />

placebo-controlled trial evaluating the efficacy of zoledronic acid 4 mg administered every<br />

3 weeks in 422 patients with HRPC <strong>for</strong> 15 months, with an option to continue <strong>for</strong> an additional<br />

9 months.<br />

o At the 2-year analysis, treatment with zoledronic acid was found to significantly reduce the<br />

percentage of patients with at least one skeletal-related event (SRE; defined as radiation <strong>for</strong><br />

bone pain or to prevent pathological fracture/spinal cord compression; pathological fracture;<br />

spinal cord compression; surgery to bone; change in antineoplastic therapy) compared with<br />

placebo (38% versus 49%; p=0.028). All SREs were delayed.<br />

o Zoledronic acid also significantly delayed the time to first SRE by around 6 months (median<br />

488 versus 321 days; p=0.009). Furthermore, patients in the zoledronic acid group had<br />

consistently lower incidences of all types of SRE than the placebo group. Pain scores were<br />

consistently lower in patients taking zoledronic acid 4mg than placebo, and significantly<br />
