DIVA Trial:
The Dosing IntraVenous Administration (DIVA) trial was a 2-year, randomized, double-blind, double-dummy, phase III, noninferiority trial designed to confirm that once-quarterly injectable dosing was as effective as daily dosing in increasing lumbar spine BMD at year 1. Women with postmenopausal osteoporosis (N=1358) were assigned one of three ibandronate regimens including 2.5 mg daily (n=457) and 3 mg once-quarterly injection (n=459). All patients took 400 IU vitamin D and 500 mg calcium supplementation daily. Values represent intent-to-treat population.
Responder analysis:
At year 2, BONIVA Injection was clinically proven to maintain or increase BMD from baseline in4,5:
— 9 out of 10 patients at lumbar spine
— 4 out of 5 patients at total hip and trochanter
— 3 out of 4 patients at femoral neck
All daily bisphosphonate therapies for the treatment and prevention of postmenopausal osteoporosis were approved by demonstrating fracture reduction versus placebo. Approval of extended dosing regimens for bisphosphonates was based on demonstrating increases in bone mineral density (BMD) similar to those of the approved daily dose.
BONE Trial:

significantly reduces vertebral fracture risk vs placebo

The Oral IBandronate Osteoporosis Vertebral Fracture Trial in North America and Europe (BONE) consisted of 2946 women aged 55 to 80 years with postmenopausal osteoporosis. In this 3-year, double-blind trial, women were randomized to one of three regimens, including placebo (n=975) and BONIVA 2.5 mg daily (n=977). All patients took 400 IU vitamin D and 500 mg calcium supplementation each day. The primary endpoint was the incidence of new vertebral fractures after 3 years of treatment.
BONE Trial:
BONIVA
significantly increases BMD as early as 6 months
