Radius Health Announced Today That it Has Acquired the License to Develop and Market RAD1901 in Japan, and Has Hired Dinesh Purandare, Former Sanofi Oncology Executive to the Position of Senior Vice President (SVP) and Head of Global Oncology at Radius

WALTHAM, Mass., March 9, 2015 (GLOBE NEWSWIRE) -- Radius Health, Inc. (Nasdaq:RDUS), a science-driven biopharmaceutical company developing new therapeutics for patients with advanced osteoporosis as well as other serious endocrine-mediated diseases including hormone responsive cancers, today announced several updates for the investigational drug RAD1901, and its oncology business. RAD1901 is being evaluated at high doses as a SERD for potential use in metastatic breast cancer and at lower doses as a SERM for vasomotor symptoms. Radius announced today that it has obtained a license to develop and market RAD1901 in Japan from Eisai. On June 29, 2006, Radius had acquired the ex-Japan rights to RAD1901 and now has the full global rights to develop and commercialize this potential new therapy. Terms were not disclosed for the acquisition of Japanese rights to RAD1901.

Radius Health also continues to build its senior corporate leadership team, and expand its presence in oncology. To that end, the company is pleased to announce that on March 18, Dinesh Purandare will join as SVP and Head of Global Oncology, reporting to Radius President and CEO Robert E. Ward. Most recently, Dinesh was Vice President and Project Head for Sanofi Oncology based in Cambridge, MA. Prior to that he led the Global Oncology Marketing for Sanofi. Oncology. Prior to joining Sanofi, Dinesh served as VP and Head of Oncology Center of Excellence at the GSK Headquarters in the UK.

"We are excited to have attracted such an experienced and respected leader in oncology as Dinesh with deep knowledge of development, commercialization, and market access," said Radius Health CEO, Robert E. Ward. "Over his career, he has served as the brand CEO in bringing multiple tumor therapeutics from development through the full commercial life cycle. Dinesh leads several successful product launches including Aromasin and Tyverb in breast cancer and his experience and capabilities will be immensely valuable as we continue the development of RAD1901 in breast cancer in major markets around the world, now including Japan."

About The Investigational Drug RAD1901

Radius is developing the investigational agent RAD1901 as a potential treatment for estrogen positive (ER+) cancers, like breast, ovarian or endometrial cancer. Currently we are focusing our clinical research activities in breast cancer. The National Cancer Institute estimates that approximately 70% of breast cancers are ER+ and may grow in response to exposure to estrogen. Endocrine therapy is intended to block the estrogen signal or reduce the production of estrogen. More information about breast cancer and endocrine therapy may be found on the National Cancer Institute website http://www.cancer.gov/cancertopics/factsheet/Therapy/hormone-therapy-breast.

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+ breast cancer in preclinical testing and complete suppression of the FES-PET signal after six days of dosing in a maximum tolerated dose 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 addition, we believe that RAD1901 also has the ability to cross the blood-brain barrier. 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.

Radius is recruiting patients for a Phase 1 multicenter, open-label, two-part, dose-escalation study of the investigational drug RAD1901 in postmenopausal women with advanced estrogen receptor positive and HER2-negative breast cancer. The study is designed to determine the recommended Phase 2 dose of RAD1901, and includes a preliminary evaluation of the potential anti-tumor effects. The incidence of Dose Limiting toxicities will be assessed during the first 28 days. Tumor response will be evaluated in patients with measurable or evaluable disease, using RECISTv1.1 guidelines every 8 weeks until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 12 months of treatment. Plasma concentrations of RAD1901 will be assessed every 28 days for up to 12 months of treatment. The details of the planned Phase 1 study of RAD1901 in breast cancer metastases are posted on www.clinicaltrials.gov.

Radius is also developing RAD1901 at lower doses as a SERM, for the potential treatment of vasomotor symptoms. Historically, hormone replacement therapy, or HRT, with estrogen or progesterone was considered the most efficacious approach to relieving menopausal symptoms such as hot flashes. However, because of the concerns about the potential long-term risks and contraindications associated with HRT, we believe a significant need exists for new therapeutic treatment options to treat vasomotor symptoms. 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. We intend to commence a Phase 2b trial in vasomotor symptoms in the second half of 2015.
