Radius, 3M Drug Delivery Systems Sign Development Agreement for Transdermal Delivery of BA058 for Treatment of Osteoporosis

CAMBRIDGE, Mass. and ST. PAUL, Minn., May 24, 2011 /PRNewswire/ -- Radius Health, Inc. ("Radius") and 3M Drug Delivery Systems ("3M") today announced an agreement to collaborate on the development of a transdermal delivery option of BA058, Radius' novel, proprietary PTHrP (parathyroid hormone-related protein) analog, for the treatment of osteoporosis.

The BA058 Microneedle Patch will use 3M's patented Microstructured Transdermal System microneedle technology to administer BA058 through the skin, as an alternative to subcutaneous injection. The BA058 patch is expected to combine the ease, convenience, and self-administration attributes of a transdermal patch with the speed and efficiency of a traditional injection. Terms of the agreement were not disclosed.

"Poor adherence to prescribed osteoporosis therapy is a common and serious problem. Patients who drop their treatment unknowingly place themselves at high risk of fracture, which exacts an enormous toll in terms of human and economic cost," said C. Richard Lyttle, PhD, President and Chief Executive Officer of Radius. "By providing a more convenient treatment alternative to injection that can promote improved compliance, the BA058 Microneedle Patch will be well-positioned to drive expansion of the osteoporosis market."

Radius' BA058 Microneedle Patch product is currently undergoing Phase 1 clinical studies. The company's recently concluded Phase 2 human testing of an injectable form of BA058 showed that BA058 significantly increased bone mineral density (BMD) at the lumbar spine and femoral neck (a common osteoporotic fracture site located in the hip joint) after six months of therapy, with greater BMD gains relative to Forteo®, the reference drug used in the study.

"We are pleased to partner with Radius, a company with deep domain expertise in osteoporosis," said Jim Vaughan, Division Vice President and General Manager of 3M Drug Delivery Systems Division. "This collaboration continues the validation of 3M's microneedle patch technology and provides an excellent example of how our technology adds value for promising new therapeutic agents. We look forward to merging 3M's innovative microneedle technology with Radius' promising bone-building agent to bring this important new therapy to market."
