Benefits of Bonviva/Boniva for the treatment of post menopausal osteoporosis
A new approach towards compliance
Roche announced today the results from the first year of a phase III study (DIVA) investigating an intravenous injection of Bonviva/Boniva (ibandronate) with extended intervals between dosages, for the treatment of post menopausal osteoporosis. Both regimens studied (2mg every 2 months and 3mg every 3 months) were at least equivalent to the 2.5 mg daily regimen in increasing spine Bone Mineral Density (BMD). Dosing by intravenous injection is predicted to provide advantages to some patients who would find it helpful for compliance or for tolerance of therapy.
The US Food and Drug Administration (FDA) approved a once-daily formulation of Boniva in May 2003 and the European Commission approval for Bonviva was received in February 2004. A supplemental new drug application for once-monthly Boniva in osteoporosis was submitted to the FDA in May 2004.
"This study demonstrates Bonviva/Boniva given once every two or three months as an injection shows promise in the management of post menopausal osteoporosis. Bonviva/Boniva will be the first intravenous bisphosphonate, and the first monthly oral treatment, giving doctors and patients flexibility and choice in the management of osteoporosis" commented William M. Burns, Head of Roche Pharmaceuticals Division. "We will be sharing these data with the regulatory authorities at the earliest possible opportunity to supplement the oral filings."
DIVA Study Details
The DIVA1 (Dosing IntraVenous Administration) is a 2 year multinational study in postmenopausal women that compares the efficacy and safety of the FDA approved oral daily ibandronate regimen with intravenous injections of ibandronate: 2 mg every 2 months and 3 mg every 3 months.
DIVA is a non-inferiority study with lumbar spine Bone Mineral Density (BMD) at one year as the primary endpoint. The study is currently ongoing for a second year.
In December 2001, Roche and GSK announced that they would co-develop and co-promote Bonviva/Boniva for the treatment and prevention of postmenopausal osteoporosis in all countries, except Japan.
