Waltham, Massachusetts — August 4, 2016 (GLOBE NEWSWIRE): Radius Health, Inc. (“Radius” or the “Company”) (Nasdaq:RDUS), a science-driven biopharmaceutical company that is committed to developing innovative therapeutics in the areas of osteoporosis, oncology and endocrine diseases, reported its financial results for the second quarter ended June 30, 2016, and provided a business update.  As of June 30, 2016, Radius had $400.9 million in cash, cash equivalents and marketable securities.

“We are pleased to be working with the U.S. Food and Drug Administration and European Medicines Agency as they review our regulatory submissions for abaloparatide-SC for the treatment of postmenopausal osteoporosis. In anticipation of our first potential launch, we are building our commercial organization in the U.S. and continuing our productive partnering discussions”, said Robert Ward, President and Chief Executive Officer of Radius.  “At the same time, we continue to make steady progress in the development of an optimized transdermal patch line extension for abaloparatide as well as the advancement of our two oncology programs, both of which we believe can add substantial value to Radius.”

Pipeline Updates

Abaloparatide-SC

In May 2016, Radius’ new drug application (“NDA”) in the United States for abaloparatide-SC for the treatment of postmenopausal women with osteoporosis was accepted for filing by the FDA and was granted a Prescription Drug User Fee Act (PDUFA) date of March 30, 2017. Radius’ marketing authorisation application (“MAA”) to the European Medicines Agency (“EMA”), was validated in December 2015 and is currently undergoing regulatory review. We anticipate a CHMP scientific opinion in late 2016 or 2017.

Abaloparatide-TD

Radius is developing abaloparatide-transdermal, or abaloparatide-TD, based on 3M’s patented Microstructured Transdermal System technology for potential use as a short wear-time transdermal patch. Radius commenced a human replicative clinical evaluation of the optimized abaloparatide-TD patch in December 2015 with the goal of achieving comparability to abaloparatide-SC. An abstract submitted to the American Society for Bone Mineral Research 2016 Annual Meeting (ASBMR) was accepted as an oral late-breaking presentation to be made on September 19, 2016 in Atlanta, Georgia.

RAD1901

In December 2014, Radius commenced a Phase 1 multicenter, open-label, two-part, dose-escalation study of RAD1901 in postmenopausal women with estrogen receptor positive (ER+) and HER2-negative advanced breast cancer in the United States.  The Phase 1 study is designed to evaluate escalating doses of RAD1901 in Part A.  The Part B expansion cohorts allow for an evaluation of additional safety, tolerability and preliminary efficacy. In addition, in December 2015, Radius commenced a Phase 1 FES-PET study in patients with ER+, HER2-negative advanced breast cancer in the European Union, which includes the use of FES-PET imaging to assess estrogen receptor occupancy in tumor lesions following RAD1901 treatment.

As of the end of July, the Phase I Part B expansion cohort for RAD1901 that initiated in March 2016 at 400 mg daily in ER+, HER2-negative advanced breast cancer has enrolled 19 out of 20 patients. We continue to enroll patients in the European Phase I FES-PET trial — the first three-patient dosing cohort is enrolled. We are pleased with the progress across these trials and expect to provide an update on the RAD1901 program at an upcoming scientific meeting.

RAD140

We have reported that RAD140 in preclinical xenograft models of breast cancer has demonstrated potent tumor growth inhibition when administered alone or in combinations with CDK4/6 inhibitors. It is estimated that 77% of breast cancers show expression of the androgen receptor. Our preclinical data suggest that RAD140 activity at the androgen receptor stimulates up-regulation of a tumor suppression pathway. We expect to provide an update on the RAD140 program at an upcoming scientific meeting.

Recent Corporate Highlights

·                  In July 2016, Radius entered into a pre-clinical collaboration with Takeda Pharmaceutical Company Limited (TSE:4502) to evaluate the combination of investigational drug RAD1901 with investigational drug TAK-228, an oral mTORC 1/2 inhibitor in Phase 2b development for the treatment of breast, endometrial and renal cancer, with the goal of potentially exploring such combination in a clinical study.

·                  In June, Radius announced the opening of its Wayne, Pennsylvania office, which will serve as the Company’s Commercial and Medical hub and house marketing, sales, human resources, IT, pharmacovigilance, health economics outcomes, medical education, clinical affairs and medical affairs staff.

·                  In May, Radius announced that its New Drug Application (NDA) for abaloparatide—SC had been accepted for filing by the U.S. Food and Drug Administration (FDA).  The acceptance of the NDA reflects the FDA’s determination that the application is sufficiently complete to permit a substantive review. A PDUFA date of March 30, 2017 has been assigned.

Abaloparatide-SC as a treatment for postmenopausal women with osteoporosis is an investigational product and its safety and efficacy have not been established.

Second Quarter 2016 Financial Results

For the three months ended June 30, 2016, Radius reported a net loss of $43.4 million, or $1.01 per share, as compared to a net loss of $23.0 million, or $0.61 per share for the three months ended June 30, 2015. The increase in net loss for the three months ended June 30, 2016 as compared to the three months ended June 30, 2015 was primarily due to an increase in research and development and general and administrative expenses, partially offset by a decrease in interest expense and an increase in interest income.

Research and development expenses for the three months ended June 30, 2016 were $26.9 million, compared to $16.3 million for the same period in 2015. This increase was primarily driven by higher professional contract services costs associated with the development of RAD1901 to support a Phase 1 study in metastatic breast cancer that commenced in late 2014 and a Phase 2b study in postmenopausal vasomotor symptoms that commenced in December 2015. This increase was also a result of an

4

increase in compensation expense, including stock-based compensation, due to an increase in headcount from June 30, 2015 to June 30, 2016.

General and administrative expenses for the three months ended June 30, 2016 were $17.2 million, compared to $6.0 million for the same period in 2015. This increase was primarily attributable to an increase in professional support costs and legal fees, including the costs associated with increasing headcount and preparing for the potential commercialization of abaloparatide-SC, subject to a favorable regulatory review.

This increase was also driven by an increase in compensation expense due to an increase in headcount from June 30, 2015 to June 30, 2016.

As of June 30, 2016, Radius had $400.9 million in cash, cash equivalents and marketable securities.  Based upon Radius’ cash, cash equivalents and marketable securities balance, Radius believes that, prior to the consideration of revenue from the potential future sales of any of its investigational products that may receive regulatory approval or proceeds from collaboration activities, it has sufficient capital to fund its development plans, U.S. commercial scale-up and other operational activities into 2018.

About Abaloparatide

Abaloparatide is an investigational therapy for the potential treatment of women with postmenopausal osteoporosis who are at an increased risk for a fracture. Abaloparatide is a novel synthetic peptide that engages the parathyroid hormone receptor (PTH1 receptor) and was selected for clinical development based on its favorable bone building activity.

Abaloparatide has completed Phase 3 development for potential use as a daily self-administered injection (abaloparatide-SC). In the fourth quarter of 2015, Radius’ Marketing Authorisation Application (MAA) for abaloparatide-SC for the treatment of patients with postmenopausal osteoporosis was validated and is currently undergoing regulatory review by the European Medicines Agency (EMA). Radius submitted a New Drug Application (NDA) for abaloparatide-SC to the US Food and Drug Administration (FDA) at the end of the first quarter of 2016, which has been accepted for filing with a PDUFA date of March 30, 2017. Radius also is developing abaloparatide-transdermal (abaloparatide-TD) based on 3M’s patented Microstructured Transdermal System technology for potential use as a treatment for osteoporosis.

About RAD1901

RAD1901 is a selective estrogen receptor down-regulator/degrader (SERD), which at high doses is being evaluated for potential use as an oral non-steroidal treatment for hormone-driven, or hormone-resistant, breast cancer. RAD1901 is currently being investigated for potential use in postmenopausal women with estrogen receptor positive (ER+), HER2-negative advanced breast cancer, the most common form of the disease.

6

Studies completed to date indicate that the compound has the potential for use as a single agent or in combination with other therapies for the treatment of breast cancer.

RAD1901 also is being evaluated in a Phase 2b study at low doses for potential relief of the frequency and severity of moderate to severe hot flashes in postmenopausal women with vasomotor symptoms. Additional information on the clinical trial program of RAD1901 is available on www.clinicaltrials.gov.

RAD140

RAD140 is a nonsteroidal selective androgen receptor modulator. The androgen receptor (AR) is highly expressed in many estrogen receptor (ER)-positive, ER-negative, and triple-negative receptor breast cancers. Because of its receptor and tissue selectivity, potent activity, oral bioavailability, and long half-life, RAD140 could have clinical potential in the treatment of breast cancer. RAD140 resulted from an internal drug discovery program focused on the androgen receptor pathway, which is highly expressed in many breast cancers.
