Amgen To Present New Data Showcasing Extensive Portfolio And Exciting Early Oncology Pipeline At ASH 2018

THOUSAND OAKS, Calif., Nov. 1, 2018 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced that new clinical data will be presented at the 60(th) American Society of Hematology (ASH) Annual Meeting & Exposition in San Diego, Dec. 1-4, 2018. Data across an array of malignancies will be featured in 45 abstracts, including nine oral presentations, from the Company's broad portfolio and early-stage pipeline.

The breadth of data to be presented at ASH this year represent Amgen's continued search for answers to complex scientific questions, leveraging its long-standing expertise in blood cancers to develop early immuno-oncology pipeline candidates and innovative biologics in areas of significant unmet need. Notable data include two oral presentations on first-in-human studies evaluating two early-stage bi-specific T cell engager (BiTE(®)) molecules - AMG 420 and AMG 330. BiTE(®) molecules are designed to harness the immune system and can be modified in an effort to enable cytotoxic T cells in the body to recognize cancer cells and destroy them. Additional data from Amgen's hematology franchise will also be featured, including long-term overall survival (OS) data for BLINCYTO(®) (blinatumomab) in patients who had achieved complete minimal residual disease (MRD) response and for once-weekly dosing of KYPROLIS(®) (carfilzomib) in combination with dexamethasone.

"For nearly four decades, Amgen has been at the forefront of cutting-edge science that has helped change treatment paradigms for patients with difficult-to-treat blood cancers. Today, we are on the cusp of a new wave of advances that harness the body's own immune system to transform cancer care," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "We're excited to present the first data from our early oncology pipeline, including two investigational BiTE(®) candidates, which demonstrate our commitment to tackling the toughest scientific questions for cancer patients."

About BiTE(®) Technology
Bispecific T cell engager (BiTE(®)) antibody construct is an innovative technology that can be engineered to target any tumor antigen expressed by any type of cancer. The protein molecules are designed to kill malignant cells using the patient's own immune system by bridging T cells to tumor cells. BiTE(®) antibody construct helps connect the T cells to the targeted cell, with the intent of causing T cells to inject toxins which trigger cancer cell death (apoptosis). Amgen is developing BiTE(® )antibody constructs to uniquely (or specifically) target numerous hematologic malignancies and solid tumors.

About BLINCYTO(®) (blinatumomab)
BLINCYTO is a bispecific CD19-directed CD3 T cell engager (BiTE(®)) immunotherapy that binds to CD19 expressed on the surface of cells of B-lineage origin and CD3 expressed on the surface of effector T cells. BLINCYTO was granted breakthrough therapy and priority review designations by the U.S. Food and Drug Administration (FDA) in 2014, and now carries full approval in the U.S. for the treatment of relapsed or refractory B-cell precursor ALL in adults and children. In the U.S., BLINCYTO is also approved under accelerated approval for the treatment of adults and children with B-cell precursor ALL in first or second complete remission with minimal residual disease (MRD) greater than or equal to 0.1 percent.

BLINCYTO is now approved in 57 countries, including all member countries in the European Union and the European Economic Area, Canada, Japan, and Australia.

    --  Relapsed or refractory Bcell precursor acute lymphoblastic leukemia
        (ALL)

IMPORTANT SAFETY INFORMATION

WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGICAL TOXICITIES

    --  Cytokine Release Syndrome (CRS), which may be life-threatening or fatal,
        occurred in patients receiving BLINCYTO(®). Interrupt or discontinue
        BLINCYTO(®) as recommended.
    --  Neurological toxicities, which may be severe, life-threatening or fatal,
        occurred in patients receiving BLINCYTO(®). Interrupt or discontinue
        BLINCYTO(®) as recommended.

Contraindications

BLINCYTO(®) is contraindicated in patients with a known hypersensitivity to blinatumomab or to any component of the product formulation.

Warnings and Precautions

    --  Cytokine Release Syndrome (CRS): CRS, which may be life-threatening or
        fatal, occurred in patients receiving BLINCYTO(®). The median time to
        onset of CRS is 2 days after the start of infusion. Closely monitor
        patients for signs and symptoms of serious adverse events such as fever,
        headache, nausea, asthenia, hypotension, increased alanine
        aminotransferase (ALT), increased aspartate aminotransferase (AST),
        increased total bilirubin (TBILI), and disseminated intravascular
        coagulation (DIC). The manifestations of CRS after treatment with
        BLINCYTO overlap with those of infusion reactions, capillary leak
        syndrome (CLS), and hemophagocytic histiocytosis/macrophage activation
        syndrome (MAS). In clinical trials of BLINCYTO, CRS was reported in 15%
        of patients with relapsed or refractory ALL and in 7% of patients with
        MRD-positive ALL. Interrupt or discontinue BLINCYTO(® )as outlined in
        the PI.
    --  Neurological Toxicities: Approximately 65% of patients receiving
        BLINCYTO(®) in clinical trials experienced neurological toxicities. The
        median time to the first event was within the first 2 weeks of
        BLINCYTO(®) treatment and the majority of events resolved. The most
        common (>= 10%) manifestations of neurological toxicity were headache
        and tremor. Severe, life?threatening, or fatal neurological toxicities
        occurred in approximately 13% of patients, including encephalopathy,
        convulsions, speech disorders, disturbances in consciousness, confusion
        and disorientation, and coordination and balance disorders.
        Manifestations of neurological toxicity included cranial nerve
        disorders. Monitor patients for signs or symptoms and interrupt or
        discontinue BLINCYTO(®) as outlined in the PI.
    --  Infections: Approximately 25% of patients receiving BLINCYTO(®) in
        clinical trials experienced serious infections such as sepsis,
        pneumonia, bacteremia, opportunistic infections, and catheter-site
        infections, some of which were life-threatening or fatal. Administer
        prophylactic antibiotics and employ surveillance testing as appropriate
        during treatment. Monitor patients for signs or symptoms of infection
        and treat appropriately, including interruption or discontinuation of
        BLINCYTO(®) as needed.
    --  Tumor Lysis Syndrome (TLS), which may be life-threatening or fatal, has
        been observed. Preventive measures, including pretreatment nontoxic
        cytoreduction and on-treatment hydration, should be used during
        BLINCYTO(®) treatment. Monitor patients for signs and symptoms of TLS
        and interrupt or discontinue BLINCYTO(®) as needed to manage these
        events.
    --  Neutropenia and Febrile Neutropenia, including life-threatening cases,
        have been observed. Monitor appropriate laboratory parameters
        (including, but not limited to, white blood cell count and absolute
        neutrophil count) during BLINCYTO(®) infusion and interrupt
        BLINCYTO(®) if prolonged neutropenia occurs.
    --  Effects on Ability to Drive and Use Machines: Due to the possibility of
        neurological events, including seizures, patients receiving BLINCYTO(®)
        are at risk for loss of consciousness, and should be advised against
        driving and engaging in hazardous occupations or activities such as
        operating heavy or potentially dangerous machinery while BLINCYTO(®) is
        being administered.
    --  Elevated Liver Enzymes: Transient elevations in liver enzymes have been
        associated with BLINCYTO(®) treatment with a median time to onset of 3
        days. In patients receiving BLINCYTO(®), although the majority of these
        events were observed in the setting of CRS, some cases of elevated liver
        enzymes were observed outside the setting of CRS, with a median time to
        onset of 19 days. Grade 3 or greater elevations in liver enzymes
        occurred in approximately 7% of patients outside the setting of CRS and
        resulted in treatment discontinuation in less than 1% of patients.
        Monitor ALT, AST, gamma-glutamyl transferase (GGT), and TBILI prior to
        the start of and during BLINCYTO(®) treatment. BLINCYTO(®) treatment
        should be interrupted if transaminases rise to > 5 times the upper limit
        of normal (ULN) or if TBILI rises to > 3 times ULN.
    --  Pancreatitis: Fatal pancreatitis has been reported in patients receiving
        BLINCYTO(®) in combination with dexamethasone in clinical trials and
        the post-marketing setting. Evaluate patients who develop signs and
        symptoms of pancreatitis and interrupt or discontinue BLINCYTO(®) and
        dexamethasone as needed.
    --  Leukoencephalopathy: Although the clinical significance is unknown,
        cranial magnetic resonance imaging (MRI) changes showing
        leukoencephalopathy have been observed in patients receiving
        BLINCYTO(®), especially in patients previously treated with cranial
        irradiation and antileukemic chemotherapy.
    --  Preparation and administration errors have occurred with BLINCYTO(®)
        treatment. Follow instructions for preparation (including admixing) and
        administration in the PI strictly to minimize medication errors
        (including underdose and overdose).
    --  Immunization: Vaccination with live virus vaccines is not recommended
        for at least 2 weeks prior to the start of BLINCYTO(®) treatment,
        during treatment, and until immune recovery following last cycle of
        BLINCYTO(®).
    --  Risk of Serious Adverse Reactions in Pediatric Patients due to Benzyl
        Alcohol Preservative: Serious and fatal adverse reactions including
        "gasping syndrome," which is characterized by central nervous system
        depression, metabolic acidosis, and gasping respirations, can occur in
        neonates and infants treated with benzyl alcohol-preserved drugs
        including BLINCYTO(®) (with preservative). When prescribing
        BLINCYTO(®) (with preservative) for pediatric patients, consider the
        combined daily metabolic load of benzyl alcohol from all sources
        including BLINCYTO(®) (with preservative) and other drugs containing
        benzyl alcohol. The minimum amount of benzyl alcohol at which serious
        adverse reactions may occur is not known. Due to the addition of
        bacteriostatic saline, 7-day bags of BLINCYTO(®) solution for infusion
        with preservative contain benzyl alcohol and are not recommended for use
        in any patients weighing < 22 kg.

Adverse Reactions

    --  The most common adverse reactions (>= 20%) in clinical trial experience
        of patients with MRD-positive B-cell precursor ALL (BLAST Study) treated
        with BLINCYTO(®) were pyrexia, infusion related reactions, headache,
        infections (pathogen unspecified), tremor, and chills. Serious adverse
        reactions were reported in 61% of patients. The most common serious
        adverse reactions (>=2%) included pyrexia, tremor, encephalopathy,
        aphasia, lymphopenia, neutropenia, overdose, device related infection,
        seizure, and staphylococcal infection.
    --  The most common adverse reactions (>= 20%) in clinical trial experience
        of patients with Philadelphia chromosome-negative relapsed or refractory
        B-cell precursor ALL (TOWER Study) treated with BLINCYTO(®) were
        infections (bacterial and pathogen unspecified), pyrexia, headache,
        infusion-related reactions, anemia, febrile neutropenia,
        thrombocytopenia, and neutropenia. Serious adverse reactions were
        reported in 62% of patients. The most common serious adverse reactions
        (>= 2%) included febrile neutropenia, pyrexia, sepsis, pneumonia,
        overdose, septic shock, CRS, bacterial sepsis, device related infection,
        and bacteremia.
    --  Adverse reactions that were observed more frequently (>= 10%) in the
        pediatric population compared to the adult population were pyrexia (80%
        vs. 61%), hypertension (26% vs. 8%), anemia (41% vs. 24%),
        infusion-related reaction (49% vs. 34%), thrombocytopenia (34% vs. 21%),
        leukopenia (24% vs. 11%), and weight increased (17% vs. 6%).
    --  In pediatric patients less than 2 years old (infants), the incidence of
        neurologic toxicities was not significantly different than for the other
        age groups, but its manifestations were different; the only event terms
        reported were agitation, headache, insomnia, somnolence, and
        irritability. Infants also had an increased incidence of hypokalemia
        (50%) compared to other pediatric age cohorts (15-20%) or adults (17%).

Dosage and Administration Guidelines

    --  BLINCYTO(®) is administered as a continuous intravenous infusion at a
        constant flow rate using an infusion pump which should be programmable,
        lockable, non-elastomeric, and have an alarm.
    --  It is very important that the instructions for preparation (including
        admixing) and administration provided in the full Prescribing
        Information are strictly followed to minimize medication errors
        (including underdose and overdose).

Please see full Prescribing Information, including Boxed WARNINGS and Medication Guide, for BLINCYTO(®).

About Multiple Myeloma
Multiple myeloma is an incurable blood cancer, characterized by a recurring pattern of remission and relapse.(1) It is a rare disease that accounts for approximately two percent of all cancers.(2) Worldwide, approximately 114,000 people are diagnosed with multiple myeloma each year and 80,000 patient deaths are reported on an annual basis.(2)

About KYPROLIS(®) (carfilzomib)
Proteasomes play an important role in cell function and growth by breaking down proteins that are damaged or no longer needed.(3) KYPROLIS has been shown to block proteasomes, leading to an excessive build-up of proteins within cells.(4) In some cells, KYPROLIS can cause cell death, especially in myeloma cells because they are more likely to contain a higher amount of abnormal proteins.(3,4)

Since its first approval in 2012, approximately 80,000 patients worldwide have received KYPROLIS. KYPROLIS is approved in the U.S. for the following:

    --  In combination with dexamethasone or with lenalidomide plus
        dexamethasone for the treatment of patients with relapsed or refractory
        multiple myeloma who have received one to three lines of therapy.
    --  As a single agent for the treatment of patients with relapsed or
        refractory multiple myeloma who have received one or more lines of
        therapy.

KYPROLIS is also approved in Argentina, Australia, Bahrain, Canada, Hong Kong, Israel, Japan, Kuwait, Lebanon, Macao, Mexico, Thailand, Colombia, South Korea, Turkey, United Arab Emirates, Qatar, Switzerland, Russia, Brazil, India, Oman and additional U.S. regulatory applications for KYPROLIS are underway and have been submitted to health authorities worldwide.

Important U.S. KYPROLIS(®) (carfilzomib) Safety Information

Cardiac Toxicities

    --  New onset or worsening of pre-existing cardiac failure (e.g., congestive
        heart failure, pulmonary edema, decreased ejection fraction),
        restrictive cardiomyopathy, myocardial ischemia, and myocardial
        infarction including fatalities have occurred following administration
        of KYPROLIS. Some events occurred in patients with normal baseline
        ventricular function. Death due to cardiac arrest has occurred within
        one day of administration.
    --  Monitor patients for signs or symptoms of cardiac failure or ischemia.
        Evaluate promptly if cardiac toxicity is suspected. Withhold KYPROLIS
        for Grade 3 or 4 cardiac adverse events until recovery, and consider
        whether to restart at 1 dose level reduction based on a benefit/risk
        assessment.
    --  While adequate hydration is required prior to each dose in Cycle 1,
        monitor all patients for evidence of volume overload, especially
        patients at risk for cardiac failure. Adjust total fluid intake as
        clinically appropriate.
    --  For patients >= 75 years, the risk of cardiac failure is increased.
        Patients with New York Heart Association Class III and IV heart failure,
        recent myocardial infarction, conduction abnormalities, angina, or
        arrhythmias may be at greater risk for cardiac complications and should
        have a comprehensive medical assessment prior to starting treatment with
        KYPROLIS and remain under close follow-up with fluid management.

Acute Renal Failure

    --  Cases of acute renal failure, including some fatal renal failure events,
        and renal insufficiency adverse events (including renal failure) have
        occurred. Acute renal failure was reported more frequently in patients
        with advanced relapsed and refractory multiple myeloma who received
        KYPROLIS monotherapy. Monitor renal function with regular measurement of
        the serum creatinine and/or estimated creatinine clearance. Reduce or
        withhold dose as appropriate.

Tumor Lysis Syndrome

    --  Cases of Tumor Lysis Syndrome (TLS), including fatal outcomes, have
        occurred. Patients with a high tumor burden should be considered at
        greater risk for TLS. Adequate hydration is required prior to each dose
        in Cycle 1, and in subsequent cycles as needed. Consider uric acid
        lowering drugs in patients at risk for TLS. Monitor for evidence of TLS
        during treatment and manage promptly, and withhold until resolved.

Pulmonary Toxicity

    --  Acute Respiratory Distress Syndrome (ARDS), acute respiratory failure,
        and acute diffuse infiltrative pulmonary disease such as pneumonitis and
        interstitial lung disease have occurred. Some events have been fatal. In
        the event of drug?induced pulmonary toxicity, discontinue KYPROLIS.

Pulmonary Hypertension

    --  Pulmonary arterial hypertension (PAH) was reported. Evaluate with
        cardiac imaging and/or other tests as indicated. Withhold KYPROLIS for
        PAH until resolved or returned to baseline and consider whether to
        restart based on a benefit/risk assessment.

Dyspnea

    --  Dyspnea was reported in patients treated with KYPROLIS. Evaluate dyspnea
        to exclude cardiopulmonary conditions including cardiac failure and
        pulmonary syndromes. Stop KYPROLIS for Grade 3 or 4 dyspnea until
        resolved or returned to baseline. Consider whether to restart based on a
        benefit/risk assessment.

Hypertension

    --  Hypertension, including hypertensive crisis and hypertensive emergency,
        has been observed, some fatal. Control hypertension prior to starting
        KYPROLIS. Monitor blood pressure regularly in all patients. If
        hypertension cannot be adequately controlled, withhold KYPROLIS and
        evaluate. Consider whether to restart based on a benefit/risk
        assessment.

Venous Thrombosis

    --  Venous thromboembolic events (including deep venous thrombosis and
        pulmonary embolism) have been observed. Thromboprophylaxis is
        recommended for patients being treated with the combination of KYPROLIS
        with dexamethasone or with lenalidomide plus dexamethasone. The
        thromboprophylaxis regimen should be based on an assessment of the
        patient's underlying risks.
    --  Patients using hormonal contraception associated with a risk of
        thrombosis should consider an alternative method of effective
        contraception during treatment.

Infusion Reactions

    --  Infusion reactions, including life?threatening reactions, have occurred.
        Symptoms include fever, chills, arthralgia, myalgia, facial flushing,
        facial edema, vomiting, weakness, shortness of breath, hypotension,
        syncope, chest tightness, or angina. These reactions can occur
        immediately following or up to 24 hours after administration.
        Premedicate with dexamethasone to reduce the incidence and severity of
        infusion reactions. Inform patients of the risk and of symptoms and seek
        immediate medical attention if they occur.

Hemorrhage

    --  Fatal or serious cases of hemorrhage have been reported. Hemorrhagic
        events have included gastrointestinal, pulmonary, and intracranial
        hemorrhage and epistaxis. Promptly evaluate signs and symptoms of blood
        loss. Reduce or withhold dose as appropriate.

Thrombocytopenia

    --  KYPROLIS causes thrombocytopenia with recovery to baseline platelet
        count usually by the start of the next cycle. Monitor platelet counts
        frequently during treatment. Reduce or withhold dose as appropriate.

Hepatic Toxicity and Hepatic Failure

    --  Cases of hepatic failure, including fatal cases, have occurred. KYPROLIS
        can cause increased serum transaminases. Monitor liver enzymes regularly
        regardless of baseline values. Reduce or withhold dose as appropriate.

Thrombotic Microangiopathy

    --  Cases of thrombotic microangiopathy, including thrombotic
        thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS), including
        fatal outcome have occurred. Monitor for signs and symptoms of TTP/HUS.
        Discontinue if diagnosis is suspected. If the diagnosis of TTP/HUS is
        excluded, KYPROLIS may be restarted. The safety of reinitiating KYPROLIS
        is not known.

Posterior Reversible Encephalopathy Syndrome (PRES)

    --  Cases of PRES have occurred in patients receiving KYPROLIS. If PRES is
        suspected, discontinue and evaluate with appropriate imaging. The safety
        of reinitiating KYPROLIS is not known.

Increased Fatal and Serious Toxicities in Combination with Melphalan and Prednisone in Newly Diagnosed Transplant-ineligible Patients

    --  In a clinical trial of transplant-ineligible patients with newly
        diagnosed multiple myeloma comparing KYPROLIS, melphalan, and prednisone
        (KMP) vs bortezomib, melphalan, and prednisone (VMP), a higher incidence
        of serious and fatal adverse events was observed in patients in the KMP
        arm. KMP is not indicated for transplant-ineligible patients with newly
        diagnosed multiple myeloma.

Embryo-fetal Toxicity

    --  KYPROLIS can cause fetal harm when administered to a pregnant woman.
    --  Females of reproductive potential should be advised to avoid becoming
        pregnant while being treated with KYPROLIS and for 6 months following
        the final dose. Males of reproductive potential should be advised to
        avoid fathering a child while being treated with KYPROLIS and for 3
        months following the final dose. If this drug is used during pregnancy,
        or if pregnancy occurs while taking this drug, the patient should be
        apprised of the potential hazard to the fetus.

ADVERSE REACTIONS

    --  The most common adverse reactions in the combination therapy trials:
        anemia, neutropenia, diarrhea, dyspnea, fatigue, thrombocytopenia,
        pyrexia, insomnia, muscle spasm, cough, upper respiratory tract
        infection, hypokalemia.
    --  The most common adverse reactions in monotherapy trials: anemia,
        fatigue, thrombocytopenia, nausea, pyrexia, dyspnea, diarrhea, headache,

Forward-Looking Statements
This news release contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for us to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and we expect similar variability in the future. Even when clinical trials are successful, regulatory authorities may question the sufficiency for approval of the trial endpoints we have selected. We develop product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as we may have believed at the time of entering into such relationship. Also, we or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market.

Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. If we fail to meet the compliance obligations in the corporate integrity agreement between us and the U.S. government, we could become subject to significant sanctions. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to acquire other companies or products and to integrate the operations of companies we have acquired may not be successful. A breakdown, cyberattack or information security breach could compromise the confidentiality, integrity and availability of our systems and our data. Our stock price is volatile and may be affected by a number of events. Our business performance could affect or limit the ability of our Board of Directors to declare a dividend or our ability to pay a dividend or repurchase our common stock. We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.

The scientific information discussed in this news release relating to new indications for our products is preliminary and investigative and is not part of the labeling approved by the European Medicines Agency for the products. The products are not approved for the investigational use(s) discussed in this news release, and no conclusions can or should be drawn regarding the safety or effectiveness of the products for these uses.
