Keypad question 1 • What bisphosphonate do you mainly use for treating metastatic bone disease? • Clodronate • Pamidronate • Zoledronic acid • Bondronat
Keypad question 2 • Do you consider intravenous or oral bisphosphonates to be more effective against skeletal complications from metastatic bone disease? • Intravenous more effective • Oral more effective • Both the same
What do patients need from their bisphosphonate? • Prevention of skeletal complications –a standard of care • Rapid and sustained relief from metastatic bone pain • Favorable safety profile

What are the benefits of Bondronat’s renal safety for routine clinical practice?
Intravenous Bondronat is simple Zometa (zoledronic acid). European SmPC. Novartis, April 2005 Bondronat (ibandronate). European SmPC. Roche, October 2003
Unchanged renal labeling for Bondronat • No renal function monitoring mandatory for Bondronat • Can be used in patients with severe renal impairment (<30mL/min creatinine clearance) • intravenous 2mg every 3–4 weeks (similar AUCto 6mg dose) Bondronat (ibandronate). European SmPC. Roche, October 2003
Implications of Bondronatrenal safety for the patient • No added renal safety risks and complications • Fewer hospital visits for renal management or monitoring • Reduces risk of bisphosphonate or chemotherapy discontinuation • Minimizes interaction with concomitant medications that have renal elimination or toxicity • Improves quality of life
Bondronat achieves better outcomes in metastatic bone disease: summary Proven efficacy • Proven efficacy in SREs across tumor types • Unmatched rapid relief of metastatic bone pain • Equivalent bone marker efficacy to zoledronic acid Favorable safety profile • Well tolerated for up to 4 years of treatment • No renal safety concerns, even with loading-dose Loading-dose Bondronat . . . it works!
