Radius Completes Enrollment for Phase 2 Study of BA058-Transdermal Patch for Treatment of Postmenopausal Osteoporosis


1/4/2013 8:55:06 AM

CAMBRIDGE, MA--(Marketwire - January 03, 2013) -

Radius Health, Inc. ("Radius"), a biopharmaceutical company focused on developing new therapeutics for the treatment of osteoporosis and other women's health conditions, completed enrollment for its randomized Phase 2 study of BA058-transdermal (BA058-TD) in healthy postmenopausal women with osteoporosis. The last of 250 patients completed her randomization visit for the Phase 2 study of this short wear-time transdermal patch based on 3M's patented Microstructured Transdermal System technology to administer BA058 without the need for subcutaneous injection.

Radius, which launched its new website this month at www.radiuspharm.com, is developing BA058, a novel synthetic peptide analog of human Parathyroid Hormone related Protein ("hPTHrP") that is a bone anabolic compound with the potential to treat severe osteoporosis. Currently, BA058 is also being studied as a daily subcutaneous injection (BA058-SC) in a Phase 3 study with 2,400 patients for fracture prevention in women with severe postmenopausal osteoporosis, in addition to the Phase 2 study of the transdermal patch, which is designed to improve patient compliance. Radius and 3M Drug Delivery Systems announced in December 2012 an exclusive agreement for the development and commercialization of the BA058-TD short wear time patch.

"With both studies underway, we are excited about the opportunity to improve treatment for patients with osteoporosis, a dramatically underserved patient population," said Michael Wyzga, Radius president and chief executive officer. "Our Phase 2 data for the BA058-SC demonstrates strong clinical evidence of bone-building capability, and with enrollment now complete in the Phase 2 transdermal patch trial, we seek to translate these results into a next generation, short wear time patch, which we hope will improve the therapeutic experience and compliance for patients with postmenopausal osteoporosis."

The Phase 2 BA058-transdermal study is a randomized, double-blind, placebo-controlled trial, designed to evaluate the safety and efficacy of BA058-TD in otherwise healthy postmenopausal women with osteoporosis, as assessed by changes in bone mineral density (BMD). In addition, pharmacokinetic parameters and serum markers of bone metabolism for BA058-TD will be compared to both transdermal placebo and BA058-SC.

"Phase 1 study data for BA058-TD showed that a five-minute patch wear time delivers peak drug levels consistent with subcutaneous injection," said Dr. Michael Bolognese, of Bethesda Health Research in Maryland and an investigator in the study. "We look forward to studying this potentially innovative treatment that has the potential to provide patients with an effective bone-building alternative to a daily subcutaneous injection. Our hope is patient compliance could increase with this novel mode of drug delivery."

Radius previously announced positive results from a series of BA058-TD Phase 1 clinical trials which successfully demonstrated the ability of the transdermal patch to safely and rapidly deliver BA058 after a short wear time, with no increased delivery resulting from longer wear, as well as supportive biochemical evidence of bone-building activity following seven days of dosing.

The previous Phase 1 pharmacokinetic studies have provided a strong basis for the current Phase 2 BA058-TD trial with key findings to date including:

Key findings from the PK study include:

  • Rapid release of BA058 from the transdermal patch
  • Peak transdermal drug levels consistent with BA058 subcutaneous injection
  • Faster time to reach peak concentration as well as more rapid elimination compared to subcutaneous injection
  • Increase in the serum bone-formation marker P1NP in serum after seven days of exposure, consistent with bone-building activity
  • Identification of an optimal wear time of 5 minutes or less, as well as effective sites of application

Additional study details can be found at www.clinicaltrials.gov.

Radius Health's new website at www.radiuspharm.com was developed by LaVoie Group Strategic Communications. The site features details on the disease areas Radius focuses on, including osteoporosis and menopause, as well as information on Radius' development pipeline.
