Prolia Scientific Support

Prolia has been studied in close to 10,000 postmenopausal women enrolled in clinical trials of up to 10 years in duration (4,886 Prolia vs. 4,886 comparator arms).1

FREEDOM Study

The FREEDOM (Fracture REduction Evaluation of Denosumab in Osteoporosis Every 6 Months) study is Prolia’s pivotal phase III, randomized, double-blind, controlled study completed of 7,808 postmenopausal women.1,2

The safety profile and efficacy of Prolia were evaluated in the FREEDOM trial and the results were published in the New England Journal of Medicine. FREEDOM’s primary endpoint was the incidence of new vertebral fracture over a period of 36 months. Secondary endpoints included the time to first nonvertebral fracture and time to first hip fracture.2

7,808 women between the ages of 60 and 91 years old with BMD T scores less than -2.5 and not less than -4.0 at the lumbar spine or total hip were enrolled in FREEDOM and randomized to receive either Prolia or placebo.1*

Key Findings

The key finding in the 3-year study was that patients taking Prolia had a significant reduction in the risk of new fracture at all measured sites (vertebral, hip, nonvertebral) compared with those taking placebo.

In the long-term, open-label extension, among 2,343 women who received Prolia in FREEDOM and continued on therapy (years 4 through 10 of Prolia treatment), 1,343 (57.3%) completed 10 years. Prolia treatment maintained a low incidence of new vertebral fractures in years 4 through 10 (7.0% had at least one new vertebral fracture).1

In the long-term, open-label extension, Prolia treatment also continued to increase BMD from extension baseline at the lumbar spine (10.8%; n=1,264), total hip (3.4%; n=1,232), and femoral neck (3.8%; n=1,232) over years 4 through 10. Percent increase in BMD from the original FREEDOM study baseline (i.e. after 10 years of treatment) in the long-term group was 21.7% at the lumbar spine, 9.2% at the total hip, and 9.0% at the femoral neck.
