Radius Health Reports Second Quarter 2014 Financial and Operating Results

·                  Management to host conference today at 8:30 am EDT

Waltham, Massachusetts - August 12, 2014: Radius Health, Inc. (“Radius”) (Nasdaq:RDUS), a science-driven biopharmaceutical company focused on developing novel differentiated therapeutics for patients with osteoporosis as well as other serious endocrine-mediated diseases, reported its financial results for the second quarter ended June 30, 2014, and provided recent corporate highlights.

“The second quarter of 2014 marked a significant milestone for the company with the completion of our initial public offering providing us with capital that we expect to be sufficient to complete the development of our lead  product candidate Abaloparatide-SC (subcutaneous) and submit an NDA/MAA in mid-2015,” said Robert Ward, President and Chief Executive Officer of Radius Health. “Our Phase 3 study (ACTIVE) evaluating Abaloparatide-SC, a novel synthetic peptide analog or PTHrP for the reduction of fractures in osteoporosis is nearing completion, and we anticipate the top-line fracture data to read-out in late December 2014.”

Recent Corporate Highlights

Initial Public Offering

In June 2014, Radius completed an initial public offering of 6,500,000 shares and closed on an additional 512,744 shares upon the exercise of a portion of the over-allotment option.  As a result, Radius received aggregate proceeds, net of underwriting discounts, commissions and offering costs of approximately $50.2 million.

Abaloparatide-SC

Radius is currently on track to announce the top-line 18-month fracture data from its Phase 3 clinical study of Abaloparatide-SC at the end of the fourth quarter of 2014 and projects the last patient visit to take place by November 2014.

In June 2014, the company presented three abstracts for Abaloparatide-SC at the joint meeting of the International Society of Endocrinology and the US Endocrine Society (ICE/ENDO 2014) in Chicago, Illinois, June 21-24, 2014. These included presentations of clinical data on the consistency of bone mineral density (“BMD”) increases with Abaloparatide-SC in two Phase 2 clinical studies, the efficacy of Abaloparatide-TD (transdermal) in a Phase 2 clinical study, and nonclinical data related to the differential PTH receptor conformation binding selectivity of abaloparatide compared to PTH and PTHrP.

In anticipation of an expected commercial launch of Abaloparatide-SC globally in 2016, Radius has recently completed market research among high-prescribers in the osteoporosis treatment market which confirmed that increases in BMD and safety are of high importance when these physicians make a choice of which injectable biologic or peptide to prescribe.  Radius’ research found that prescribers would find a new agent with faster and greater BMD increases at all sites to be highly desirable. Radius expects that the worldwide injectable osteoporosis treatment market will grow to be $2.5 billion or greater by 2016 when it expects to launch Abaloparatide-SC globally.  Radius is currently exploring collaboration opportunities with companies that can help it accelerate the launch of this potential best in disease therapeutic around the world.

RAD1901

In June 2014, Radius initiated a Phase 1 maximum tolerated dose (“MTD”) study in healthy volunteers for another key pipeline asset, RAD1901, a selective estrogen receptor degrader (“SERD”), for the treatment of metastatic breast cancer, including breast cancer brain metastases.  The study is designed to evaluate the tolerability, safety and pharmacokinetics of RAD1901, and also use 18F-fluroestradiol positron emission tomography to provide a pharmacodynamic assessment of estrogen receptor turnover following RAD1901 treatment. Levels of RAD1901 in cerebrospinal fluid samples taken from the study subjects will be measured to confirm that RAD1901 has crossed the blood brain barrier. Radius believes there is a significant therapeutic opportunity for RAD1901 as it may offer the following advantages over the current standard of care for patients with metastatic breast cancer:

·                  ability to penetrate the blood-brain barrier;

·                  oral administration; and

·                  treatment of hormone driven, or hormone resistant, metastatic breast cancers.

Anticipated Upcoming Milestones

·                  Abaloparatide-SC

·                  Report of top-line fracture data from Abaloparatide-SC Phase 3 clinical study in late December 2014.

·                  Submit a New Drug Application/NDA and a European Marketing Authorization Application/MAA for Abaloparatide-SC in mid-2015.

·                  RAD1901

·                  Initiate a Phase 1 clinical study of RAD1901 in metastatic breast cancer in late 2014.

·                  Report results of MTD study of RAD1901.

·                  Presentations

·                  American Society of Bone and Mineral Research 2014 annual meeting in September 2014.

·                  Canaccord Annual Growth Conference (August 2014), BioCentury Annual NewsMakers Conference (September 2014), BIO Investor Forum (October 2014) and Jefferies 2014 Global Healthcare Conference (November 2014).

Second Quarter 2014 Financial Results

For the three months ended June 30, 2014, Radius reported a net loss of $12.6 million, or $2.22 per share, as compared to a net loss of $19.5 million, or $62.59 per share for the same period in 2013.  The net loss per share calculation for the three months ended June 30, 2014 includes the weighted average impact of Radius’ convertible preferred stock converting into common stock upon the completion of its initial public offering in June 2014.  The decrease in net loss for the 2014 period was primarily due to a decrease in research and development expenses.

Research and development expenses for the three months ended June 30, 2014 were $10.6 million, compared to $16.2 million for the same period in 2013. The decrease for the 2014 period was primarily attributable to a decrease in the costs associated with the Abaloparatide-SC Phase 3 clinical trial as it nears completion, and a decrease in the costs incurred for the development of Abaloparatide-TD, for which a Phase 2 clinical trial was completed in September 2013.  These reductions in cost were partially offset by an increase in the costs associated with the advancement of RAD1901.

As of June 30, 2014, Radius had $79.0 million in cash, cash equivalents and marketable securities, compared to $12.3 million on December 31, 2013. On June 11, 2014, Radius achieved an important milestone with the completion of its initial public offering. Radius sold 6,500,000 shares of common stock at a price of $8.00 per share and began trading on the NASDAQ Global Market on June 6, 2014. On June 18, 2014 and June 25, 2014, the underwriters purchased an additional 512,744 shares in the aggregate by exercising a portion of the over-allotment option granted to them in connection with the initial public offering.  As a result of the closing of the initial public offering and subsequent exercise of the over-allotment option, Radius received aggregate proceeds, net of underwriting discounts, commissions and offering costs, of approximately $50.2 million.
