American Society for Bone and Mineral Research
Radius Health, Inc. presented on September 12-15, 2014 at the American Society for Bone and Mineral Research (ASBMR) 2014 Annual Meeting in Houston certain preclinical and clinical data from studies of abaloparatide, an investigational drug currently being evaluated in the Phase 3 ACTIVE trial as a potential therapeutic for the reduction of osteoporotic fracture risk.
At the ASBMR 2014 Annual Meeting, Radius Health presented a poster entitled: "Responder Analysis of the Effects of Abaloparatide and Teriparatide on Bone Mineral Density in Postmenopausal Osteoporosis," and results from this 24-week randomized controlled trial indicated that significantly more women treated with abaloparatide experienced increases in bone mineral density at the spine, femoral neck and total hip (66%) (abaloparatide as compared to teriparatide, p-value<0.05; abaloparatide as compared to placebo, p-value<0.01) as compared to the controls (teriparatide 40%, and placebo 29%). The potential clinical significance of these data is being evaluated in the ongoing Phase 3 ACTIVE trial and is subject to regulatory review of the entire package of data from our abaloparatide development program.
An oral presentation of the most recent preclinical data for abaloparatide was also given in the Osteoporosis Treatment section of the ASBMR 2014 Annual Meeting. In a study of osteopenic primates administered abaloparatide daily for 16 months, the results indicated a continued, significant, bone mineral density increase at the spine and femoral neck throughout the 16-month period accompanied by a commensurate increase in strength without increases in cortical porosity. The potential clinical significance of these data also is being evaluated in the ongoing Phase 3 ACTIVE trial.
Radius Health is nearing the completion of its pivotal Phase 3 ACTIVE fracture prevention trial in 2,400 postmenopausal osteoporotic women randomized to either placebo or 18 months of daily subcutaneous administration with abaloparatide or Eli Lilly's Forteo. As set forth in the protocol, the primary endpoint for the ACTIVE trial is the comparison of the vertebral fracture rate in the placebo and abaloparatide arms. Radius Health expects the last patient in the 18-month daily administration portion of the trial to complete their last visit under the trial protocol by November 2014 and to announce the top line results from the ACTIVE trial in December 2014.
Annual Brain Metastases Research and Emerging Therapy Conference
Radius Health presented an update on September 19, 2014 at the 4th Annual Brain Metastases Research and Emerging Therapy Conference 2014 in Marseille, France, from the ongoing Phase 1 maximum tolerated dose (MTD) study of its investigational drug RAD1901. The Phase 1 MTD clinical study is being conducted in healthy postmenopausal female volunteers to determine the MTD, safety, tolerability and pharmacokinetics (PK) of RAD1901 in these healthy volunteers. The study also includes subjects in which 18F-estradiol positron emission tomography (FES-PET) is used to assess estrogen receptor engagement. The study data presented at the conference from the first healthy volunteer in the PET imaging cohort of the study suggest that RAD1901 suppresses estrogen receptor signal according to FES-PET after 6-days of daily treatment. Following successful completion of the MTD clinical study, the potential clinical significance of these and other data on RAD 1901 must be evaluated in future clinical trials.
Radius believes that previously-completed preclinical studies have established the potential for RAD1901 to be a small molecule tissue-selective estrogen receptor degrader (SERD) that could selectively bind and degrade the estrogen receptor (ER) with the ability to cross the blood-brain barrier and oral bioavailability. In mouse xenograft studies, treatment with RAD1901 decreased estradiol-induced breast cancer tumor growth. Preclinical studies have also indicated that RAD1901 has the potential to be bone protective in a rat ovariectomy-induced osteoporosis model.
Upcoming Company Presentations
Radius Health will also be presenting at the 13th Annual BIO Investor Forum at The Palace Hotel in San Francisco on Tuesday, October 7, 2014 at 1:30 p.m. PT (4:30 p.m. ET). At 3:30 p.m. PT, President and CEO, Robert Ward will also be participating as a Panelist for the BIO Investor Forum Business Roundtable "JOBS Act, from Enactment to IPO: Surprises from the CEOs in the First Generation".
About the Investigational Drug Abaloparatide
Radius' investigational drug abaloparatide (BA058) is a synthetic peptide analog of human parathyroid hormone-related protein (hPTHrP), a naturally occurring bone-building hormone that we believe has the potential to increase bone mineral density. Abaloparatide SC is an investigational drug currently in Phase 3 development for potential use as a daily self-administered injection for the treatment of patients with postmenopausal osteoporosis at high risk of fracture. This potential is currently being studied in our ongoing active Phase 3 trial (ACTIVE) and is subject to regulatory review of the entire package of data from our abaloparatide development program. Topline results from an ongoing Phase 3 pivotal trial comparing abaloparatide SC daily injection to placebo and an active comparator for the prevention of new vertebral fractures are expected in December 2014. Radius is also developing the investigational drug 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
In June 2014, Radius initiated a Phase 1 MTD study in healthy volunteers, of its investigational drug RAD1901, a SERD, being developed for potential use in the treatment of metastatic breast cancer, including breast cancer brain metastases. As set forth in the protocol, the study is designed to evaluate the tolerability, safety and pharmacokinetics of RAD1901 in healthy volunteers, 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 determine that RAD1901 has crossed the blood-brain barrier.
Radius believes that there potentially could be a significant therapeutic opportunity for its investigational drug RAD1901 if it is successfully developed and cleared for marketing following completion of its development program, as RAD1901 may offer the following potential clinical options for patients with metastatic breast cancer:
- Protect the skeleton from loss of bone mineral density;
- Ability to penetrate the blood-brain barrier;
- Oral administration; and
- Treatment of hormone driven, or hormone resistant, metastatic breast cancers.
Radius is also developing RAD1901 as an investigational selective estrogen receptor modulator, or SERM, for potential use in the treatment of vasomotor symptoms. Data from a completed Phase 2 proof of concept study demonstrated that RAD1901 at lower doses has the potential to reduce the frequency and severity of moderate and severe hot flashes.
