Radius Health Reports First Quarter 2015 Financial and Operating Results

• Management to host conference call today at 7:30 am ET

WALTHAM, Mass., May 6, 2015 (GLOBE NEWSWIRE) -- Radius Health, Inc. ("Radius") (Nasdaq:RDUS), a science-driven biopharmaceutical company focused on developing new therapeutics for patients with osteoporosis as well as other serious endocrine-mediated diseases, including hormone responsive breast cancer, reported its financial results for the first quarter ended March 31, 2015, and provided recent corporate highlights. As of March 31, 2015, Radius had cash, cash equivalents and marketable securities of $243.1 million, including $158.4 million in proceeds from a public offering on January 28, 2015, net of underwriting discounts and offering costs.

"Radius has already achieved a number of significant milestones in 2015, including a successful follow-on offering in January," said Robert Ward, President and Chief Executive Officer of Radius Health. "We are taking the necessary steps to achieve our critical priorities in 2015: preparing for our NDA and MAA submissions for the investigational drug abaloparatide-SC, seeking a global collaborator and planning for the potential commercial launch of abaloparatide-SC following regulatory approval. In oncology, we are pleased to be continuing to enroll and dose patients in our Phase 1 study for the investigational drug RAD1901 to evaluate its potential in the treatment of metastatic breast cancer."

Pipeline Update

Abaloparatide-SC

On April 28, 2015, additional positive data from the Phase 3 ACTIVE study of our investigational drug abaloparatide-SC, "Treatment with Abaloparatide Significantly Reduces Wrist Fractures Compared to Teriparatide", was presented in the HOT TOPICS Session at the ECTS-IBMS 2015 Congress. This presentation focused on data from a post-hoc analysis (not prespecified in the study protocol or the original or amended statistical analysis plan for the ACTIVE trial) relating to the effects seen for abaloparatide on bone mineral density and fracture risk at the wrist. The post-hoc analysis showed that abaloparatide, as compared to teriparatide, showed a significant 72% reduction in wrist fractures. Any potential clinical significance of these data will be evaluated during the anticipated regulatory review of these and all other data from the ACTIVE trial.

In the ACTIVE Phase 3 clinical trial, abaloparatide-SC demonstrated the largest reduction ever reported in vertebral fracture risk versus placebo of 86%. Importantly, the ACTIVE trial demonstrated that abaloparatide-SC resulted in more bone growth, at more skeletal sites, and in more patients than an open-label arm in which the current standard of care was administered. These data indicate that the unique structure and mechanism of abaloparatide translate to a longer anabolic window and reduced calcium resorption versus native PTH, which, subject to regulatory review, may have clinical significance at some of the most difficult to treat non-vertebral sites, such as the hip, wrist and femoral neck.

Radius is on track to report the results of the first six months of the ACTIVExtend trial at the end of the second quarter of 2015. Patients from the abaloparatide-SC and placebo groups from the ACTIVE clinical trial were eligible to continue in ACTIVExtend, in which they are receiving an approved alendronate therapy for osteoporosis management. The results from this ACTIVExtend six month period will be combined with the 18 month Phase 3 ACTIVE results to provide the complete 24-month data set. This will form the basis of Radius' planned submission of a new drug application ("NDA") to the U.S. Food and Drug Administration ("FDA") and of a marketing authorization application ("MAA") to the European Medicines Agency ("EMA"), in the second half of 2015. We currently anticipate a standard review at the FDA and EMA with, pending a positive regulatory outcome, first commercial sales of abaloparatide in 2016.

During the quarter, Radius continued the nonhuman primate pharmacokinetic studies of the investigational drug abaloparatide‑TD, a short wear time transdermal patch form of abaloparatide. In December 2014, we reported that a prototype achieved a desirable pharmacokinetic profile, with comparable AUC, Cmax, Tmax and T1/2 relative to abaloparatide-SC. Radius expects to initiate the clinical evaluation of the optimized abaloparatide-TD patch in the second half of 2015, with the goal of achieving comparability to abaloparatide-SC.

RAD1901

Radius is continuing to enroll and dose patients in the United States in the Phase 1 clinical trial of the investigational drug RAD1901 for potential use in the treatment of metastatic breast cancer. The Phase 1 study is a multicenter, open-label, two-part, dose-escalation study of RAD1901 in postmenopausal women with advanced estrogen receptor positive and HER2-negative breast cancer that is designed to determine the recommended dose for a Phase 2 study and includes a preliminary evaluation of the potential anti-tumor effect of RAD1901. Radius expects to report an update on the Phase 1 study at the American Society of Clinical Oncology Annual Meeting that is scheduled to take place May 29-June 2, 2015, and to report further progress on this study in the second half of 2015. Radius plans to initiate Phase 1 clinical development in the European Union for RAD1901 in metastatic breast cancer patients in 2015.

During the quarter, Radius secured worldwide rights for RAD1901 by amending its license agreement with Eisai Co. Ltd. This is an important step as Radius looks to expand the potential therapeutic profile for RAD1901.

First Quarter 2015 Financial Results

For the three months ended March 31, 2015, Radius reported a net loss of $17.1 million, or $0.47 per share, as compared to a net loss of $14.5 million, or $50.45 per share for the three months ended March 31, 2014. The net loss per share calculation for the three months ended March 31, 2015 includes the impact of the conversion of Radius' convertible preferred stock into common stock upon the completion of its initial public offering in June 2014. The increase in net loss for the three months ended March 31, 2015 as compared to the three months ended March 31, 2014 was primarily due to an increase in general and administrative and research and development expenses, which was partially offset by a decrease in other (expense) income, net.

Research and development expenses for the three months ended March 31, 2015 were $11.6 million, compared to $9.7 million for the same period in 2014. The increase for the 2015 period as compared to the 2014 period was primarily attributable to an increase in compensation costs, including non-cash stock-based compensation costs, due to increases in employee headcount and an increase in consulting costs incurred to support the NDA submission for abaloparatide-SC. These increases were partially offset by a decrease in the costs associated with the abaloparatide-SC Phase 3 clinical trial.

General and administrative expenses for the three months ended March 31, 2015 were $4.8 million, compared to $2.1 million for the same period in 2014. The increase for the 2015 period as compared to the 2014 period was primarily attributable to an increase in consulting support costs and legal fees, as well as higher compensation costs, including non-cash stock-based compensation expense.

For the three months ended March 31, 2015, other (expense) income, net, was $(50) thousand, as compared to $(2.2) million for the same period in 2014. Other (expense) income, net, for the 2015 period primarily represents state tax expenses. Other (expense) income, net, for the 2014 period reflected changes in the fair value of Radius' stock liability, other liability and warrant liability.

As of March 31, 2015, Radius had $243.1 million in cash, cash equivalents and marketable securities. Radius expects that its cash, cash equivalents and marketable securities of as of March 31, 2015, will carry it into the fourth quarter of 2016 and through the key milestones associated with abaloparatide and RAD1901.

About the Investigational Drug Abaloparatide

Radius' investigational drug is a novel synthetic peptide analog of parathyroid hormone-related protein (PTHrP), a naturally occurring bone-building hormone that Radius believes has the potential to increase bone mineral density by stimulating new bone formation. Abaloparatide-SC is an investigational drug currently in Phase 3 development for potential use as a daily self-administered injection for the reduction of fracture risk in postmenopausal women with severe osteoporosis. Radius is also developing abaloparatide-TD, for potential use as a short wear-time transdermal patch designed to administer abaloparatide without the need for subcutaneous injection, based on 3M's patented Microstructured Transdermal System technology.

About The Investigational Drug RAD1901

Radius is developing the investigational drug RAD1901 as a potential treatment for estrogen positive (ER-positive) cancers, like breast, ovarian or endometrial cancer. Currently, Radius is focusing our clinical research activities in breast cancer. The National Cancer Institute estimates that approximately 70% of breast cancers are ER-positive and may grow in response to exposure to estrogen. Endocrine therapy is intended to block the estrogen signal or reduce the production of estrogen.

RAD1901 is an investigational, non-steroidal small molecule that is designed to selectively bind and degrade the estrogen receptor. RAD1901 has demonstrated potent anti-tumor activity in xenograft models of ER-positive breast cancer in preclinical testing and complete suppression of the FES-PET signal in healthy volunteers after six days of dosing in a maximum tolerated dose Phase 1 clinical study. In preclinical models thus far, RAD1901 has shown good tissue selectivity, does not appear to stimulate the uterine endometrium, and appears to protect against bone loss in an ovariectomy-induced osteopenia rat model. In vitro, treatment of human breast cancer cell lines with the investigational drug RAD1901 resulted in degradation of the ER and inhibition of both basal and estradiol-stimulated proliferation.

In a Phase 2 proof of concept study, RAD1901 at lower doses demonstrated a reduction in the frequency and severity of moderate and severe hot flashes.  Radius believes a significant need exists for new therapeutic treatment options to treat vasomotor symptoms.

About Osteoporosis

According to the International Osteoporosis Foundation, it is estimated that over 200 million women worldwide suffer from osteoporosis causing more than 8.9 million fractures annually, or one every three seconds.

Breaking a bone is a serious complication of osteoporosis, especially when you're older. Broken bones due to osteoporosis are most likely to occur in the hip, spine and wrist. According to the National Osteoporosis Foundation, in the U.S. between 2000 and 2011, 4.9 million women over age 55 were hospitalized for osteoporotic fracture of the hip, pelvis, arm, leg or spine, compared to 3 million for stroke, 2.9 million for heart attack and 700,000 for breast cancer.¹

There are two categories of osteoporosis medications: antiresorptive medications that slow bone loss and anabolic drugs that increase the rate of bone formation. Bisphosphonates, calcitonin, denosumab, estrogen and estrogen agonists/antagonists are antiresorptive medicines, and slow bone loss.

Teriparatide, a form of parathyroid hormone, is an anabolic drug, and is currently the only osteoporosis medicine approved by the FDA that rebuilds bone.

In 2014, global sales of osteoporosis therapies totaled $6.4 billion, $2.3 billion of which was for injectable drugs.
