Radius Health, Inc.: Third Quarter 2021 Results

Boston, Mass., November 8, 2021 – Radius Health, Inc. (“Radius” or the “Company”) (Nasdaq: RDUS), today reported its results for the third quarter ended September 30, 2021.

Q3, 2021 FINANCIAL HIGHLIGHTS:

Our shift from a general osteoporosis sales approach to one that focuses on – primarily – the fracture patient segment continues to evolve. We have made progress and expect to make more in the future. However, due to lower-than-expected year-to-date TYMLOS net revenue, the Company is making the following changes to full year 2021 forecasts:

ELACESTRANT:

On October 20, 2021, Radius announced along with its partner the Menarini Group that EMERALD, a pivotal study evaluating elacestrant in breast cancer, was positive as a monotherapy vs. the standard of care for patients with ER+/HER2- advanced or metastatic breast cancer (mBC), including those with the Estrogen Receptor Mutation (ESR1). The study met both primary endpoints for the overall population as well as the ESR1 mutation subgroup.

Chhaya Shah, Senior Vice President and clinical program lead for Radius commented, “The study results were certainly encouraging for patients and their families, as the first oral selective estrogen receptor degrader to show positive topline data. We are working with our partner on progressing the program towards regulatory submission in the U.S. as well as Europe in 2022.”

Kelly Martin, Chief Executive Officer of Radius, elaborated, “We work closely with the Menarini Group on all aspects of the elacestrant asset – they are a terrific partner. We are collectively enthusiastic about the opportunities to bring potential benefit to patients by progressing this molecule.”

He added, “Given the significance of the positive topline data to Radius, it is important to outline key aspects of the molecule as well as the financial/business relationship that exists between the Menarini Group and ourselves.”

Martin concluded, “Creating tangible value for our capital providers is a fundamental objective of our business and central to our management approach and operating philosophy. To that end, we intend to utilize a minimum of 50% of the up to $300 million in potential future sales milestones from elacestrant to strengthen the capital structure.”

As to the detail – mentioned above – the following five (5) items are of particular relevance to Radius shareholders, capital providers, and other stakeholders:

ABALOPARATIDE:

Clinical and Regulatory

Commercial

RAD011:

All remains on track as previously communicated for Prader-Willi Syndrome (PWS). The seamless pivotal trial (SCOUT) is expected to commence in Q4, 2021 or early Q1, 2022.

We will provide a further update on the RAD011 molecule in the near term. We plan to add at least two additional neurological orphan disease indications and progress those forward with pivotal trials.

Use of Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States (GAAP), we use the following non-GAAP financial measures in this press release: non-GAAP adjusted net loss and non-GAAP net loss per share. These non-GAAP financial measures exclude certain amounts or expenses from the corresponding financial measures determined in accordance with GAAP. Management believes this non-GAAP information is useful for investors, taken in conjunction with Radius’ GAAP financial statements, because it provides greater transparency and period-over-period comparability with respect to Radius’ operating performance and can enhance investors’ ability to identify operating trends in our business. Management uses these measures, among other factors, to assess and analyze operational results and trends and to make financial and operational decisions. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of Radius’ operating results as reported under GAAP, not in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. In addition, these non-GAAP financial measures are unlikely to be comparable with non-GAAP information provided by other companies. The determination of the amounts that are excluded from non-GAAP financial measures is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts. Reconciliations between these non-GAAP financial measures and the most comparable GAAP financial measures for the three months ended September 30, 2021 and 2020 are included in the tables accompanying this press release after the unaudited condensed consolidated financial statements.

About Radius

Radius is a global biopharmaceutical company focused on addressing unmet medical needs in the areas of bone health, orphan diseases, and oncology. Radius’ lead product, TYMLOS® (abaloparatide) injection, was approved by the U.S. Food and Drug Administration for the treatment of postmenopausal women with osteoporosis at high risk for fracture. The Radius clinical pipeline includes investigational abaloparatide injection for potential use in the treatment of men with osteoporosis; an investigational abaloparatide transdermal system for potential use in the treatment of postmenopausal women with osteoporosis; the investigational drug, elacestrant (RAD1901), for potential use in the treatment of hormone-receptor positive breast cancer out-licensed to Menarini Group; and the investigational drug RAD011, a synthetic cannabidiol oral solution with potential utilization in multiple endocrine and metabolic orphan diseases, initially targeting Prader-Willi Syndrome.

About TYMLOS (abaloparatide) injection

multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy.

About ATOM Phase 3 Study

The ATOM Phase 3 study is a randomized, double-blind, placebo-controlled study to assess efficacy and safety of abaloparatide injection in 228 men with osteoporosis. The primary endpoint is change in lumbar spine BMD at 12 months compared with placebo, and it is expected to form the basis of a supplemental NDA seeking to expand the use of TYMLOS to treat men with osteoporosis at high risk for fracture.

About the Abaloparatide Transdermal System and wearABLe Phase 3 Study

The abaloparatide transdermal system was developed in a collaboration between Radius and Kindeva Drug Delivery (“Kindeva”) (formerly 3M Drug Delivery Systems) with the application of Kindeva’s innovative microstructured transdermal system technology. The wearABLe study is a pivotal, randomized, open label, active-controlled, bone mineral density (“BMD”) non-inferiority bridging study that will evaluate the efficacy and safety of abaloparatide transdermal system versus TYMLOS (abaloparatide) injection in approximately 500 patients with postmenopausal osteoporosis at high risk for fracture. The primary endpoint of the study is the percentage change in lumbar spine BMD at 12 months.

About Elacestrant (RAD1901) and EMERALD Phase 3 Study

Elacestrant is a selective estrogen receptor degrader (SERD), out-licensed to Menarini Group, which is being evaluated for potential use as a once daily oral treatment in patients with ER+/ HER2- advanced breast cancer. Studies completed prior to EMERALD 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. The EMERALD Phase 3 trial is a randomized, open label, active-controlled study evaluating elacestrant as second- or third-line monotherapy in ER+/HER2- advanced/metastatic breast cancer patients. The study has enrolled 466 patients who have received prior treatment with one or two lines of endocrine therapy, including a cyclin-dependent kinase (CDK) 4/6 inhibitor. Patients in the study were randomized to receive either elacestrant or the investigator’s choice of an approved hormonal agent. The primary endpoint of the study is progression-free survival (PFS) in the overall patient population and in patients with estrogen receptor 1 gene (ESR1) mutations. Secondary endpoints include evaluation of overall survival (OS), objective response rate (ORR), and duration of response (DOR).

About Prader-Willi Syndrome

PWS, an orphan disease, is a complex genetic disorder with clinical manifestations on the endocrine and neurological systems. Clinical signs of PWS develop throughout childhood, with hyperphagia and anxiety ranked as the key clinical features seeking medical attention by caregivers of individuals with PWS. Hyperphagia is a relentless, insatiable, pathological drive to eat that requires caregivers to strictly manage access to food through the locking of cabinets and refrigerators. PWS is recognized as the leading genetic cause of life-threatening obesity in children. As life-threatening hyperphagia persists into adulthood, metabolic syndrome expressed through obesity and diabetes can develop and contribute to morbidity and mortality. In addition to food-related behaviors, the behavioral symptoms commonly observed in PWS include high irritability, habitual skin picking, oppositional defiance and cognitive rigidity. There are currently no approved therapies to treat this disorder’s hyperphagia, irritability, or metabolic aspects. In the U.S., PWS occurs in approximately one out of every 15,000 births.

About RAD011

Investigational drug RAD011 is a pharmaceutical-grade synthetic cannabidiol oral solution, manufactured utilizing traditional pharmaceutical manufacturing processes. The product has purity specifications that meet standardized regulatory and quality control requirements and, compared to the process of developing a plant-derived product,

10

the synthetic manufacturing process usually enables increased consistency and greater precision in the product supply. RAD011 has been assessed in over 150 patients across multiple indications and has potential utilization in multiple endocrine and metabolic orphan diseases. Radius is initially targeting Prader-Willi syndrome (PWS) and anticipates initiating a seamless pivotal Phase 2/3 study for patients with PWS in the fourth quarter of 2021 or first quarter of 2022.
