Issued: London UK – LSE Announcement

In October, the European Medicines Agency (EMA) granted PRIME designation to GSK2857916 for the treatment of relapsed and refractory multiple myeloma patients whose prior therapy included a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 antibody. GSK2857916 is an anti B-cell maturation agent (BCMA) monoclonal antibody-drug conjugate.

GSK2857916 has also received orphan drug designation from the EMA and FDA for multiple myeloma.

The PRIME and Breakthrough Therapy Designations are based on results from a phase 1 open-label, dose escalation and expansion study in patients with relapsed/refractory multiple myeloma, irrespective of BCMA expression. Data from this ongoing trial will be presented on 11th December in an oral presentation at the 59th annual meeting of the American Society of Hematology (ASH) (Free ASH Whitepaper) meeting in Atlanta.

Axel Hoos, SVP Oncology R&D, GSK said "Oncology R&D at GSK is focussed on developing medicines with transformational potential for patients and we are pleased that our investigational antibody-drug conjugate is the first BCMA targeting agent to receive Breakthrough Therapy and PRIME designation. GSK plans to rapidly advance clinical trials with this promising therapy, alone and in combination with other therapies, to further investigate how GSK2857916 could benefit patients with multiple myeloma. The monotherapy data that we have seen for GSK2857916 support its transformational potential and we look forward to working with regulators as we progress the development programme."
Notes to editors

Breakthrough Therapy Designation is designed to expedite the development and review of drugs that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s). Drugs that receive breakthrough therapy designation are eligible for all features of FDA’s Fast Track Programme.[i]

PRIME designation is offered by the European Medicines Agency (EMA) to enhance support for the development of medicines that target an unmet medical need. It is based on enhanced interaction between sponsor companies and the EMA to optimise development plans and speed up evaluation so these medicines can reach patients earlier.[ii]

Orphan designation may be granted for therapies intended to treat conditions that affect fewer than 200,000 people in the U.S. The designation qualifies the sponsor of the drug for various development incentives of the Orphan Drug Act, including tax credits for qualified clinical testing[iii].

In Europe, sponsors who obtain Orphan Designation for a potential new medicine benefit from a range of incentives, including protocol assistance, access to the centralised procedure, market exclusivity and fee reductions.[iv]

Sunesis Pharmaceuticals Reports Third Quarter 2017 Financial Results and Recent Highlights

On November 2, 2017 Sunesis Pharmaceuticals, Inc. (Nasdaq:SNSS) reported financial results for the third quarter ended September 30, 2017 (Press release, Sunesis, NOV 2, 2017, View Source [SID1234521490]). Loss from operations for the three months ended September 30, 2017 was $9.9 million. As of September 30, 2017, cash, cash equivalents and marketable securities totaled $12.5 million. Subsequent to the end of the quarter, the company raised approximately $6 million from sales of common stock through its at the market facility in October 2017 and $20 million in gross proceeds from concurrent underwritten public offerings on October 27, 2017, which together will provide sufficient funds for the operation of the company’s business into early 2019.

“In the third quarter, we advanced our lead program, a reversible, non-covalent BTK inhibitor, SNS-062, with the ongoing enrollment in our Phase 1b/2 study in patients with relapsed chronic lymphocytic leukemia (CLL) and other B-cell malignancies,” said Daniel Swisher, Chief Executive Officer of Sunesis. “We will provide a program update at an investor presentation and webcast during the American Society of Hematology (ASH) (Free ASH Whitepaper) Conference in Atlanta, Georgia in December 2017, and to present interim data from the study at a peer-reviewed medical conference in mid-2018. We believe SNS-062 has the potential to overcome the leading resistance pathway to ibrutinib, the predominant standard of care for the treatment of CLL. In addition, in October, we secured the financial resources from leading life science investors extending our operating runway into early 2019.

Mr. Swisher added, “Beyond SNS-062, we have made progress with our proprietary PDK-1 and Takeda-partnered pan-RAF inhibitor programs. We are pleased to announce today the nomination of our PDK1 (phosphatidyl-inositol dependent kinase1) inhibitor, SNS-510, as a Development Candidate and potentially first-to-clinic selective inhibitor in this pathway. PDK1 is a master kinase that activates other kinases important to cell growth and survival including members of the AKT, PKC, RSK and SGK families. In addition, we look forward to announcing future updates from the ongoing clinical studies of our Takeda-partnered TAK-580 program.”

Recent Highlights

Completed $20 million concurrent public offerings with leading life science investors. On October 27, 2017, Sunesis raised $20 million in gross proceeds in concurrent underwritten public offerings of common and preferred stock and warrants, with participation by new and existing investors, including Oncology Impact Fund managed by MPM Capital, BVF Partners L.P and Burrage Capital.

Continued Progress in Phase 1b/2 Study Evaluating Oral Non-Covalent BTK-inhibitor SNS-062 in Adults with Chronic Lymphocytic Leukemia (CLL) and other B-Cell Malignancies. In July 2017, Sunesis announced that the first patient was dosed at the Dana-Farber Cancer Institute in the Phase 1b/2 dose-escalation and cohort-expansion study evaluating the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of its potent, reversible, non-covalent BTK-inhibitor, SNS-062, in adults with CLL, small lymphocytic leukemia, Waldenstrom’s macroglobulinemia, and mantle cell lymphoma. The Phase 1b/2 trial is an open-label, sequential-group study that is enrolling up to 124 subjects across leading sites in the United States. The Company plans to present interim data from this study in mid-2018.
Financial Highlights

Cash, cash equivalents and marketable securities totaled $12.5 million as of September 30, 2017, as compared to $42.6 million as of December 31, 2016. The decrease of $30.1 million was primarily due to $30.8 million of net cash used in operating activities and a debt restructuring payment of $7.6 million, partially offset by $8.3 million in net proceeds primarily from sales of common stock through the company’s at the market facility. An additional $24.6 million in net proceeds were raised in October, resulting in pro-forma September 30, 2017 cash, cash equivalents and marketable securities of $37.1 million. This capital is expected to fund the company into 2019.

Revenue for the three and nine months ended September 30, 2017 was nil and $0.7 million, as compared to $0.6 million and $1.9 million for the same periods in 2016. Revenue in each period was primarily due to deferred revenue recognized related to the Royalty Agreement with Royalty Pharma.

Research and development expense was $6.8 million and $17.9 million for the three and nine months ended September 30, 2017 as compared to $5.3 million and $18.1 million for the same periods in 2016, primarily relating to the SNS-062 and the vosaroxin development program in each period. The increase of $1.5 million between the comparable three month periods was primarily due to the $2.5 million milestone payment to Biogen under the license agreement, offset by decreases in professional services of $0.8 million and salary and personnel expenses of $0.2 million. The decrease in the comparable nine months periods of $0.2 million was primarily due to a decrease in professional services of $2.5 million, salary and personnel expenses of $0.2 million, and medical affairs expenses of $0.2 million, partially offset by the $2.5 million milestone payment to Biogen under the license agreement.

General and administrative expense was $3.2 million and $10.8 million for the three and nine months ended September 30, 2017, as compared to $3.9 million and $12.2 million for the same periods in 2016. The decrease of $0.7 million for the comparable three month periods was primarily due to decreases in salary and personnel expenses of $0.4 million and commercial expenses of $0.3 million, partially offset by increases of $0.1 million in professional services. The decrease in the comparable nine months periods of $1.4 million was primarily due to a decrease in salary and related expenses of $0.9 million, commercial expenses of $0.7 million, partially offset by increase of $0.4 million in professional services.

Interest expense was $0.3 million and $1.1 million for the three and nine months ended September 30, 2017, as compared to $0.5 million and $1.2 million for the same periods in 2016. The decrease in the 2017 periods was primarily due to the decrease in the outstanding notes payable.

Net other income was $0.1 million and $0.3 million for the three and nine months ended September 30, 2017, as compared to nil and $0.1 million for the same periods in 2016. The other income was primarily comprised of interest income from the short-term investments.

Cash used in operating activities was $30.8 million for the nine months ended September 30, 2017, as compared to $29.0 million for the same period in 2016. Net cash used in the 2017 period resulted primarily from the net loss of $28.8 million and changes in operating assets and liabilities of $4.6 million, offset by net adjustments for non-cash items of $2.6 million. Net cash used in the nine month period ended September 30, 2016 resulted primarily from the net loss of $29.5 million and changes in operating assets and liabilities of $3.6 million, including a final payment fee representing interest expense of $1.2 million under the Oxford Loan Agreement, partially offset by net adjustments for non-cash items of $4.1 million.

Sunesis reported loss from operations of $9.9 million and $28.0 million for the three and nine months ended September 30, 2017, as compared to $8.5 million and $28.4 million for the same periods in 2016. Net loss was $10.2 million and $28.8 million for the three and nine months ended September 30, 2017, as compared to $9.0 million and $29.5 million for the same periods in 2016.

“It is very encouraging for Radius to see TYMLOS gaining traction in the market,” said Jesper Høiland, President and CEO of Radius. “In addition to our stated goal of gaining market leadership for TYMLOS, we are excited by the positive response to the product by physicians, payors and patients. With the recent capital raise, we are also well funded to start investing in expanding the TYMLOS label and advancing the development of our other therapeutic candidates in the pipeline.”

“TYMLOS is proving itself to be an important treatment for a high unmet medical need, as demonstrated by the continued increase in lives covered through managed care contracts,” said David Snow, Chief Commercial Officer of Radius. “Postmenopausal women with osteoporosis at high risk for fractures deserve to have therapies that safely and effectively reduce that risk, with lower out of pocket costs. Our sales team is achieving strong reach and call frequency and we are continuing to expand payer acceptance while we see anabolic class volume stabilizing.”

TYMLOS (abaloparatide injection)

Third quarter reported sales of TYMLOS in the U.S. (the first full quarter since its launch) were approximately $3.5 million. Radius received FDA approval for TYMLOS on April 28, 2017 for the treatment of postmenopausal women with osteoporosis at high risk of fracture, and began shipments to wholesalers at the end of May 2017.

In September 2017, Radius presented results from the completed ACTIVExtend study in an abstract titled “Sustained Fracture Risk Reduction with Sequential Abaloparatide/Alendronate: Results of ACTIVExtend” at the ASBMR 2017 Annual Meeting in Denver, Colorado. In ACTIVExtend, patients who had completed 18 months of TYMLOS or placebo in the ACTIVE Phase 3 trial were transitioned to receive 24 additional months of open-label alendronate. Patients who received a sequential therapy of TYMLOS followed by alendronate demonstrated statistically significant fracture risk reductions through 3.5 years. At the 43-month timepoint, the previous TYMLOS-treated patients had a significant 84 percent relative risk reduction (p<0.0001) in the incidence of new vertebral fractures compared with women who received placebo followed by alendronate. Additionally, TYMLOS followed by alendronate demonstrated a 39 percent relative risk reduction in nonvertebral fractures (p=0.038), compared with women who received placebo followed by alendronate.

The Company expects to submit a labeling supplement to the FDA in connection with the ACTIVExtend results by the end of 2017.
Pipeline Updates

Abaloparatide — Subcutaneous (SC)

European MAA
Radius’ European Marketing Authorisation Application (MAA) for abaloparatide-SC for the treatment of postmenopausal women with osteoporosis is under review by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA). On July 21, 2017, the CHMP issued a second Day-180 List of Outstanding Issues. Radius is working with the CHMP to address these issues, and discussed preliminary responses with the Rapporteurs in a formal Clarification Meeting. We expect an opinion from the CHMP regarding the MAA prior to the end of 2017.
Male Osteoporosis Trial
We recently gained agreement with the FDA on the design of a clinical trial in men with osteoporosis, which, if successful, will form the basis of an sNDA seeking to expand the use of TYMLOS to treat men with osteoporosis at high risk for fracture. The study will be a randomized, double-blind, placebo-controlled trial that will enroll approximately 225 men with osteoporosis.
The primary endpoint is change in spine bone mineral density (“BMD”) at 12 months compared with placebo. TYMLOS has demonstrated in previous clinical trials that it increases BMD in postmenopausal women. The study will include specialized high-resolution imaging of bone structure in a subset of the study participants. We expect to initiate the trial in the first quarter of 2018.
Abaloparatide-Transdermal Patch (TD)

We have scheduled a meeting with the FDA in January 2018 to align on a regulatory pathway for a pivotal study (e.g. bioequivalence or BMD) for abaloparatide-TD and we are also discussing manufacturing arrangements with 3M Company related to potential commercial supplies of abaloparatide-TD. We are on track to complete manufacturing scale-up, production, and other required activities needed to initiate a pivotal study. The pharmacokinetic profile of an optimized abaloparatide-TD patch was successfully modified so as to improve comparability to abaloparatide-SC. We believe that the transdermal patch program, if approved, will offer patients who suffer from osteoporosis a convenient alternative.
Elacestrant (RAD1901)

In a meeting to discuss the elacestrant breast cancer development program, the FDA indicated that, depending on the study results, which must demonstrate an improvement over then available therapies, the planned single-arm Phase 2 trial could be considered a pivotal study for accelerated approval as long as a confirmatory study is ongoing by the time of the NDA submission. We will provide further study details when the Phase 2 study is initiated, which we expect will be in early 2018. In October, elacestrant received FDA Fast Track designation supporting a rapid speed to market strategy.
Elacestrant is also being evaluated at low doses as an estrogen receptor ligand for the potential relief of the frequency and severity of moderate to severe hot flashes in postmenopausal women with vasomotor symptoms. We are currently reviewing our elacestrant vasomotor development program and plan to provide an update by the end of 2017.
RAD140

In September 2017, the Company announced that the first patient had been enrolled in the Company’s Phase 1 study of RAD140, a nonsteroidal selective androgen receptor modulator (SARM) undergoing clinical evaluation for the treatment of hormone receptor positive breast cancer. The clinical trial is designed to evaluate the safety and maximum tolerated dose of RAD140 in approximately 40 patients.

Third Quarter 2017 Financial Results

Three Months Ended September 30, 2017
For the three months ended September 30, 2017, Radius reported a net loss of $57.8 million, or $1.31 per share, compared to a net loss of $46.2 million, or $1.07 per share, for the three months ended September 30, 2016.

For the three months ended September 30, 2017, Radius reported TYMLOS net product revenues of about $3.5 million, which reflects the first full quarter of recorded sales. Radius had no revenue in the three months ended September 30, 2016 as the FDA approved TYMLOS on April 28, 2017.

Research and development expense for the three months ended September 30, 2017, was $21.0 million compared to $27.5 million for the three months ended September 30, 2016, a decrease of $6.5 million, or 24%. This decrease was primarily driven by a $3.4 million decrease in vasomotor project related spending, a $2.0 million decrease in abaloparatide-SC project costs, and a $1.1 million decrease in RAD1901 oncology project costs.

Selling, general, and administrative expense for the three months ended September 30, 2017, was $47.7 million compared to $19.2 million for the three months ended September 30, 2016, an increase of $28.5 million, or 148%. This increase was primarily the result of an increase of approximately $10.1 million in professional fees and support costs, including the costs associated with increasing headcount and preparing for the commercialization of TYMLOS in the United States. This increase was also driven by a $15.2 million increase in compensation expense, including stock-based compensation, due to the increase in headcount.

Nine Months Ended September 30, 2017
For the nine months ended September 30, 2017, Radius reported a net loss of $183.2 million, or $4.21 per share, compared to a net loss of $130.1 million, or $3.02 per share, for the nine months ended September 30, 2016.

For the nine months ended September 30, 2017 Radius reported TYMLOS net product revenues of about $4.4 million, which reflects the first full quarter of reported sales. Radius had no revenue in the nine months ended September 30, 2016 as the FDA approved TYMLOS on April 28, 2017.

Research and development expense for the nine months ended September 30, 2017, was $60.2 million compared to $81.8 million for the nine months ended September 30, 2016, a decrease of $21.6 million, or 26%. This decrease was primarily driven by a $14.9 million decrease in RAD1901 project costs, a $14.1 million decrease in abaloparatide-SC project costs, and a $2.2 million decrease in development costs associated with abaloparatide-TD. This decrease was partially offset by a $9.7 million increase in compensation expense, including stock-based compensation, due to an increase in headcount.

Selling, general, and administrative expense for the nine months ended September 30, 2017, was $135.9 million compared to $50.1 million for the nine months ended September 30, 2016, an increase of $85.8 million, or 171%. This increase was primarily the result of an increase of approximately $27.9 million in professional fees and support costs during the nine months ended September 30, 2017, including the costs associated with increasing headcount and preparing for the commercialization of TYMLOS in the United States. This increase was also driven by a $49.4 million increase in compensation expense, including stock-based compensation, due to an increase in headcount.

As of September 30, 2017, Radius had $468.1 million in cash, cash equivalents and marketable securities. Based upon our cash, cash equivalents and marketable securities balance as of September 30, 2017, we believe that, prior to the consideration of proceeds from partnering and/or collaboration activities, we have sufficient capital to fund our development plans, U.S. commercial and other operational activities for not less than twelve months from the date of this press release.
