Amgen and MD Anderson Announce Agreement to Develop BiTE® Therapies for Myelodysplastic Syndrome

On January 12, 2015 Amgen and The University of Texas MD Anderson Cancer Center reported a research collaborative agreement focusing on Amgen’s bispecific T cell engager (BiTE) antibody constructs, an immunotherapy that serves as a “bridge” between T cells and cancer cells (Press release Amgen, JAN 12, 2015, View Source [SID:1234501318]).

The research agreement will identify targets for this therapy in myelodysplastic syndrome (MDS), a bone marrow disorder in which the body does not produce sufficient healthy blood cells. MDS affects primarily older adults over age 60 and can cause severe anemia, potentially leading to development of acute myelogenous leukemia (AML), a blood cell cancer.

“This is a unique collaboration that explores BiTE therapy for its potential in treating a disorder that affects thousands of people each year,” said Guillermo Garcia-Manero, M.D., professor of leukemia at MD Anderson. “At MD Anderson, we have unrivaled proteomics capabilities to explore new targets for this disease, and this novel approach may very well open up new potential treatments for our patients.”

The collaboration’s innovative approach will draw on the expertise of MD Anderson’s Moon Shots Program, which aims to accelerate the conversion of scientific discoveries into clinical advances and significantly reduce cancer deaths. Garcia-Manero leads the MDS/AML Moon Shots Program.

The collaborative agreement will allow Amgen and MD Anderson to join forces in a research partnership that aims to take new drug development from “A to Z.” The agreement provides for joint development of new agents under pre-determined terms. Amgen retains all commercial rights, while MD Anderson is eligible to receive milestones and royalties upon successful achievement of key objectives.

“We are excited about the new research opportunities this collaboration will open up in further exploring the potential of BiTE technology,” said Sean E. Harper, M.D., executive vice president of Research and Development at Amgen. “BiTE antibody constructs represent an innovative immunotherapy approach that helps the body’s immune system target cancer cells. MD Anderson is a great partner in our quest to find potential new treatments for patients with serious illnesses.”

BiTE antibody constructs are recombinant proteins consisting of two separate antibodies held together by a flexible peptide linker or bands of amino acids. The antibodies are designed to function as a link between T cells and cancer cells. One antibody or protein domain binds to the cancer cell’s surface, while the other binds to the CD3 on the T cell, resulting in the malignant cell’s death. It is thought that BiTE antibody constructs may be engineered to target a range of tumors.

“This long-term collaboration between leading scientists at MD Anderson and Amgen takes advantage of significant advances in technologies available for target discovery through the MD Anderson Moon Shots Program,” said Samir Hanash, M.D., Ph.D., professor of clinical cancer prevention and director, the Red and Charline McCombs Institute for the Early Detection and Treatment of Cancer at MD Anderson. “The agreement covers the full scope of clinical development from identifying targets for this therapy in MDS to developing fully tested and approved new therapies.”

Information on NPS Pharma
NPS Pharma is a commercial-stage rare disease-focused biopharmaceutical company, whose first product, GATTEX (teduglutide [rDNA origin]) for injection, has been launched in the U.S. to treat adults with short bowel syndrome (SBS). NPS Pharma is in the process of launching the product in Europe under the trade name REVESTIVE. NPS Pharma’s second product rhPTH -83 (NATPARA in the U.S. / NATPAR in Europe) is currently under review in the U.S. and Europe for the treatment for hypoparathyroidism (HPT). NPS Pharma has an ongoing Phase 2a study evaluating its lead pipeline candidate NPSP795 for the treatment of adults with autosomal dominant hypocalcemia. NPS Pharma has an operational presence in the U.S., Canada, Europe, Latin America and Japan. The value of NPS Pharma’s gross assets were $282.2 million with net assets totaling $130.9 million as of September 30, 2014. NPS Pharma’s losses before tax for the three and nine month periods ending September 30, 2014 were $1.9 million and $6.2 million, respectively.

Information on GATTEX/REVESTIVE
In the United States, GATTEX (teduglutide [rDNA origin]) for injection is approved for the long-term treatment of adults with short bowel syndrome (SBS) who need parenteral support. GATTEX is the first analog of GLP-2 approved to treat SBS, a disease which may require patients to get their nutrition intravenously through a central line.

SBS is a condition in which a large portion of the intestine has been removed by surgery. As a result, people can’t absorb enough nutrients or fluids from food and liquids to maintain good health. It can also be caused by disease or injury that prevents the small intestine from functioning properly despite normal length. To make up for the inadequate absorption, intravenous (IV) feeding (parenteral support) may be prescribed to help the patient stay healthy.

In the U.S., approximately 6,000-7,000 SBS patients are dependent on parenteral support with a similar prevalence in Europe.2

GATTEX has received orphan drug designation from the U.S. Food and Drug Administration (FDA) and was approved in December 2012. GATTEX generated sales of $67.9 million in the nine months ending September 30, 2014.

In Europe, REVESTIVE has been launched in Germany and Sweden.

Information on NATPARA/NATPAR
NATPARA/NATPAR, NPS Pharma’s parathyroid hormone (rhPTH -83) for the treatment of hypoparathyroidism (HPT), a rare endocrine disorder characterized by insufficient levels of parathyroid hormone (PTH), is currently under review in the U.S. with an FDA Prescription Drug User Fee Act (PDUFA) action date for the Biologics License Application (BLA) on January 24, 2015. In Europe, the European Medicines Agency (EMA) has validated and initiated its review of NPS Pharma’s marketing authorization application (MAA) for NATPAR.

HPT is a rare condition in which the parathyroid glands fail to produce sufficient amounts of PTH or where PTH lacks biologic activity. PTH plays a central role in a variety of critical physiological functions in the body. In patients with HPT, insufficient levels of PTH lead to many physiological abnormalities, including low serum calcium and an inability to convert native vitamin D into its active state to properly absorb dietary calcium.

In the U.S., approximately 75,000 patients are diagnosed with HPT with 41,000 having moderate to severe disease with a similar prevalence in EU5 (France, Germany, United Kingdom, Italy and Spain).3

Acute symptoms of HPT are largely due to low serum calcium and range from muscle pain and tingling, to lack of focus or ability to concentrate, and anxiety and depression. In extreme cases, life-threatening events, such as arrhythmias and seizures, may occur. In the absence of an approved parathyroid replacement therapy, the standard approach focuses on using large doses of calcium and active vitamin D to increase calcium levels in the blood and reduce the severity of symptoms. However, balancing the administration of large doses of calcium and vitamin D is challenging due to calcium fluctuations and the long-term use of this regimen may lead to serious complications. In addition, calcium and vitamin D do not correct the abnormal bone metabolism due to PTH deficiency or enable the activation of vitamin D.

Additional value from NPS Pharma’s licenced products and pipeline
NPS Pharma currently has several successful partnerships in place. Amgen markets cinacalcet HCl as Sensipar in the U.S. and as Mimpara in the EU; Janssen Pharmaceuticals markets tapentadol as Nucynta in the U.S.; and Kyowa Hakko Kirin markets cinacalcet HCI as Regpara in Japan, Hong Kong, Malaysia, Macau, Singapore, and Taiwan.

NPS Pharma earned royalty revenues of $123.8 million for 2013 and $89.5 million for the first nine months ending September 30, 2014.

NPS Pharma is developing teduglutide as a treatment for pediatric SBS. NPS Pharma is currently conducting a global study for teduglutide in pediatric patients with SBS who are dependent on parenteral support.

NPS Pharma is also investigating NPSP795, a small molecule antagonist of the calcium-sensing receptor, which is believed to play a role in the distribution of PTH -83 throughout the body by antagonizing calcium-sensing receptors on the parathyroid gland to trigger a release of the body’s stores of PTH -83. NPSP795 is in development as a treatment for autosomal dominant hypocalcemia (ADH). There is no approved therapy for this ultra-rare, life-long genetic disorder that affects both adults and children.

Following the above transactions, Dr. Gillis holds 674 ADSs. One ADS is equal to three ordinary shares of 5 pence each in the Company.

Financial benefit to Shire
The acquisition of NPS Pharma is expected to enhance Shire’s revenue and earnings growth profile. Shire expects the transaction to be accretive to Non GAAP EPS from 2016 onward.

Related to the acquisition, Shire anticipates that it will realize operating synergies beginning in 2016 and growing substantially thereafter. Shire anticipates synergies approximating 25-35% of the Street’s consensus forecast of NPS Pharma’s standalone future operating cost base from 2017 onward.

Shire also expects that the transaction will deliver ROIC in excess of its weighted average cost of capital.

Financing

Shire has secured an $850 million fully underwritten short-term bank facility, which, in addition to Shire’s cash and cash equivalents and its existing $2.1 billion five-year revolving credit facility, is available to finance the transaction and pay related fees and expenses. Shire plans to refinance the short-term bank facility through new debt issuances in due course.

Closing

The acquisition is structured as an all-cash tender offer for all of the outstanding shares of NPS Pharma at a price of $46.00 per share followed by a merger in which each remaining untendered share of NPS Pharma common stock would be converted into the same $46.00 cash per share consideration as in the tender offer.

The closing of the transaction is subject to customary conditions, including the tender of a majority of the outstanding NPS Pharma shares and the receipt of Hart-Scott-Rodino clearance. Pending such closing conditions, it is anticipated that the transaction will close in the first quarter of 2015.

Citigroup Global Markets Limited and Lazard are acting as joint financial advisors to Shire. Goldman, Sachs & Co. and Leerink Partners LLC are acting as financial advisors to NPS Pharma. Davis Polk & Wardwell LLP and Slaughter & May are acting as legal advisors to Shire and Skadden, Arps, Slate, Meagher & Flom LLP is acting as legal advisor to NPS Pharma.

CheckMate -017, A Phase 3 Study of Opdivo (Nivolumab) Compared to Docetaxel in Patients with Second-Line Squamous Cell Non-small Cell Lung Cancer, Stopped Early

On January 11, 2015 Bristol-Myers Squibb Company reported that an open-label, randomized Phase 3 study evaluating Opdivo versus docetaxel in previously treated patients with advanced, squamous cell non-small cell lung cancer (NSCLC) was stopped early because an assessment conducted by the independent Data Monitoring Committee (DMC) concluded that the study met its endpoint, demonstrating superior overall survival in patients receiving Opdivo compared to the control arm (Press release Bristol-Myers Squibb, JAN 11, 2015, View Source [SID:1234501315]). The company will share these data – which for the first time indicate a survival advantage with an anti-PD1 immune checkpoint inhibitor in lung cancer – with health authorities.

CheckMate -017 investigators are being informed of the decision to stop the comparative portion of the trial. Bristol-Myers Squibb is working to ensure that eligible patients will be informed of the opportunity to continue or start treatment with Opdivo in an open-label extension as part of the company’s commitment to providing patient access to Opdivo, and characterizing long-term survival. The company will complete a full evaluation of the final CheckMate -017 data and work with investigators on the future presentation and publication of the results.

About the Study

CheckMate -017 is a Phase 3, open-label, randomized study of Opdivo versus docetaxel in previously treated patients with advanced or metastatic squamous cell NSCLC. The trial randomized 272 patients to receive either nivolumab 3 mg/kg intravenously every two weeks or docetaxel 75 mg/m2 intravenously every three weeks. The primary endpoint is overall survival. Secondary endpoints include objective response rate and progression free survival.

Peripheral T-cell lymphomas (PTCL) is a set of rare and heterogeneous group of mature T- and natural killer (NK)-cell neoplasms associated with poor outcome. PTCL makes up 25 percent to 30 percent of all Non-Hodgkin’s lymphoma (NHL) cases in China, much higher than that seen in Western countries of 10 percent to 15 percent. The subtype distribution of PTCL is also significantly different between China and Western countries, in which extranodal NK/T-cell lymphoma, nasal type (ENKL), a subtype highly aggressive with very poor prognosis, to be the leading subtype in Chinese population.

"Chidamide is the first new molecular entity discovered and developed by Chipscreen scientists in China. The CFDA’s decision to approval the world first orally administrated selective HDACi for PTCLs is an important validation of the drug’s therapeutic potential for this urgent medical need for Chinese PTCLs patients. The orally administrated Chidamide not just will provide affordable innovative treatment for the Chinese patients whom otherwise have no option to obtain most up-to-dated new treatment beyond conventional chemotherapies, but also have great potential, based on its unique epigenetic mechanism of actions and existing knowledge from the field, to be easily combined with other treatment modalities in comprehensive control and management of cancer patients in fight against drug resistance and tumor recurrence," said Xian-Ping LU, Ph.D., Chief Executive Officer and Chief Scientific Officer of Chipscreen Biosciences Ltd.

About Chidamide (Epidaza)

Chidamide is an orally bioavailable, low-nanomolar inhibitor of cancer-associated histone deacetylase (HDAC) enzymes with favorable pharmacology and tolerability profiles relative to existing benzamide and non-benzamide HDAC inhibitors. It targets specifically the subtype 1, 2, 3 of Class I and subtype 10 of Class IIb HDAC and is being studied in multiple clinical trials as a single agent or in combination with chemotherapeutic agents for the treatment of various hematological and solid cancers. In clinically administrated concentrations, it demonstrated a unique epigenetic mechanism of actions against tumor cell development, involving preferential induction of growth arrest and apoptosis in blood and lymphoid-derived tumor cells, activation of NK-mediated and CD8-mediated antigen-specific cellular anti-tumor immunity, differentiation of tumor stem cells, reversal of drug-resisting tumor cells and epithelia to mesenchymal transition, which are hallmarks of treatment resistance, tumor cell metastasis and recurrence.
