FDA Approves the First Prescription Wearable for Low Bone Density

The FDA has given its approval to a wearable belt, the first non-drug prescription medical device, that administers targeted vibrations to the spine and hips to treat low bone density, a precursor to osteoporosis. Proven effective in clinical trials, this innovative device provides postmenopausal women with an alternative treatment option compared to traditional vitamin and mineral supplements.

Postmenopausal women face an elevated risk of fractures due to a decline in the hormone estrogen. Estrogen plays a crucial role in preserving bone density, and its reduction can result in osteopenia or low bone density. Osteopenia, the precursor to osteoporosis, impacts 40.4% of the global population.

FDA Approves Osteoboost, a Wearable Device by Bone Health Technologies, for Osteopenia Treatment

Created by Bone Health Technologies (BHT), Osteoboost is an innovative wearable belt device designed to deliver vibrations to the lumbar spine and hips, promoting bone growth. The FDA recently granted approval for the device to treat osteopenia, marking it as the first non-drug prescription medical device to receive such recognition.

Laura Yecies, the CEO of BHT, expressed the significance of the FDA’s decision on January 18th, stating, “Today’s groundbreaking decision represents the first non-pharmacological therapy approved to treat this widespread and serious condition. With Osteoboost, we have a new treatment option – free of serious adverse events – that taps into the body’s natural mechanism to stimulate bone growth. Women’s health has been underserved for too long, making this a huge step forward for older women who have lacked effective treatment options and are seeking an effective way to protect their bone health.”

Derived from NASA technology to counteract bone loss in zero gravity, whole-body vibration therapy (WBVT) stimulates bone growth by simulating mechanical loading akin to high-impact exercise. Previous research indicates that WBVT can encourage bone growth and prevent bone loss in postmenopausal women, particularly in the hips and lumbar spine. Typically delivered via an oscillating platform, Osteoboost, an offshoot of WBVT, provides targeted, low-intensity vibrations to the hips and lumbar spine, addressing common areas susceptible to osteoporotic fractures.

FDA Approval Based on Clinical Trial Data for Osteoboost’s Efficacy in Postmenopausal Women with Low Bone Density

The FDA’s approval of Osteoboost relied on data from a clinical trial published in the Journal of the Endocrine Society. The trial involved 126 postmenopausal women with low bone density who received Osteoboost treatment five times a week for 12 months. In the sham setting, a sound was produced, but no vibration was delivered. Stratifying participants by age revealed significant differences in percent change in vertebral bone strength, particularly in the 50-to-60-year-old group.

Those in the sham group experienced a 3.4% loss in vertebral bone strength, compared to a 0.5% loss in the active group. In participants meeting the compliance criterion of three Osteoboost treatments per week, the sham group had a 2.84% loss of bone strength, while the active group only had a 0.48% loss, indicating a five times greater loss in the sham group. Additionally, Osteoboost treatment preserved the bone density of the first lumbar vertebra (L1), with the active group showing a 0.29% loss of bone mineral density (BMD) compared to a 1.97% loss in the sham group, representing a 6.8 times greater loss in the sham group.

Lead author Laura Bilek emphasized the threat to the well-being and active lifestyle of postmenopausal women due to rapid bone loss resulting from estrogen decline. While lifestyle interventions like exercise and diet offer modest benefits, Osteoboost shows promise in slowing the loss of bone density and strength, potentially filling a treatment gap.

Regulatory Milestone

The FDA employed the De Novo classification process, offering a marketing pathway for the approval of Osteoboost through Bone Health Technologies’ (BHT) request, initially before it gained Breakthrough Device designation. This approval establishes a new therapeutic class for addressing low bone density, distinct from pharmaceutical interventions. Notably, Osteoboost stands as the first therapeutic device specifically designed and approved for use in osteopenia.

Currently, aside from calcium and vitamin D supplements, there are no other available treatments for osteopenia.

David Karpf, Adjunct Clinical Professor of Endocrinology, Gerontology, and Metabolism at Stanford University School of Medicine, highlighted the lack of innovative approaches in the field of bone health. With no new agents in clinical trials for osteoporosis and a scarcity of options for women with osteopenia, the aging population necessitates novel methods to effectively prevent the decline in bone mass and strength affecting women in the perimenopause or postmenopausal stage.
