- CX-904 demonstrated a favorable safety profile with no cytokine release syndrome (CRS) of any grade observed in step-dosing cohorts and no grade >1 CRS observed overall - - Encouraging initial signs of efficacy observed for CX-904 in advanced pancreatic cancer, including 2 of 6 patients (33%) with a confirmed partial response and all 6 patients (100%) with disease control - - Preliminary pharmacokinetic and pharmacodynamic analyses are supportive of PROBODY® T-Cell Engager platform mechanism of action - - Dose escalation and optimization continue - - Management to hold conference call today at 5 p.m. EDT / 2 p.m. PDT - May 08, 2024 -- CytomX Therapeutics, Inc. (Nasdaq: CTMX), a leader in the field of masked, conditionally activated biologic therapeutics, today announced positive initial data from the ongoing CX-904 Phase 1a dose escalation clinical study, demonstrating a favorable safety profile and confirmed anti-cancer activity. CX-904 is an investigational, masked, conditionally activated PROBODY T-cell engager designed to target the epidermal growth factor receptor (EGFR) on cancer cells and the CD3 receptor on T cells within the tumor microenvironment. “We are delighted to share these initial results today for CX-904, a highly innovative masked T-cell engager that embodies our vision at CytomX of transforming lives with safer, more effective therapies,” said Sean McCarthy, D.Phil., chief executive officer and chairman of CytomX. “These data build on more than a decade of innovation at CytomX, and, we believe, open broad new possibilities for T-cell engagers across many targets and cancer types. For EGFR specifically, a target that is present on normal epithelial tissues, we are very encouraged to see CX-904 working as designed by eliciting meaningful tumor reductions in a very difficult to treat tumor type and with a favorable overall safety profile. We look forward to continuing to explore the potential of this exciting agent in multiple EGFR positive cancers and to determining longer term strategy with our global development partner, Amgen.” As of the April 16, 2024 data cutoff, the Phase 1 study had enrolled 35 patients with advanced metastatic solid tumor types that are generally known to express EGFR, including pancreatic, colorectal (CRC), non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), gastric, and esophageal cancers. Patients enrolled in the study were heavily pre-treated and had a median of 4 prior lines of therapy. As of the data cutoff, 19 patients were enrolled into initial non-step dosing cohorts with target doses ranging from 0.007 mg to 6 mg, and 16 patients were subsequently enrolled into step-dosing cohorts with target doses ranging from 5 mg to 10 mg and with tocilizumab prophylaxis. Enrollment into a cohort with a target dose of 15 mg is ongoing. As of the cutoff date, CX-904 demonstrated a favorable safety profile that supports administration and monitoring of enrolled patients in an outpatient setting.1 There were no observed cases of CRS of any grade in step-dosing cohorts to-date. In non-step dosing cohorts, only Grade 1 CRS was observed in patients treated at the highest dose of 6 mg. Among all treated patients, the most common treatment-related adverse events (TRAEs) were rash, arthralgia, arthritis, pruritis, and vomiting, the majority of which were low grade, being observed in 14 (40%), 13 (37%), 5 (14%), 5 (14%) and 5 (14%) patients, respectively. Grade 3 TRAEs were tenosynovitis (n=1), arthralgia (n=2), arthritis (n=1), and rash (n=1). Eight patients had measurable tumor reduction at data cutoff, including 2 of 6 efficacy-evaluable patients (33%) with pancreatic cancer with confirmed partial responses per RECIST 1.1. All 6 efficacy-evaluable patients with pancreatic cancer achieved disease control (objective response or stable disease). For the two patients with a confirmed partial response, one patient (6 mg target dose) achieved an 83% tumor reduction. The second patient (5 mg target dose) with a confirmed response achieved a 51% tumor reduction and remained on study treatment as of the data cutoff. In addition, a third pancreatic cancer patient maintained stable disease with no evidence of tumor growth through 3.5 months of study treatment and remained on treatment as of the data cutoff. Preliminary pharmacokinetic and pharmacodynamic data were consistent with the PROBODY TCE mechanism of action, including maintained masking in circulation, and CD8+ T-cell margination and tumor infiltration. CX-904 Phase 1a dose escalation and optimization continue, with future enrollment focused on determining a recommended Phase 2 dose, or doses. The Company expects to provide an additional Phase 1a dose escalation update by the end of 2024. These additional data will inform discussions with CytomX partner, Amgen, towards initiation of Phase 1b expansion cohorts in specific EGFR positive tumor types. CytomX management will host a conference call and simultaneous webcast today at 5 p.m. EDT (2 p.m. PDT) to discuss the first quarter 2024 results and provide an initial CX-904 Phase 1a clinical data update. Participants may access the live webcast of the conference call from the Events and Presentations page of CytomX’s website at https://ir.cytomx.com/events-and-presentations. Participants may register for the conference call here and are advised to do so at least 10 minutes prior to joining the call. An archived replay of the webcast will be available on the company’s website for at least 30 days.

MOSAIC Study is First to use MRI to Assess Inflammation in Peripheral Joints and Entheses in Psoriatic Arthritis Patients Exploratory Analysis Examines Effects of Otezla on Cardiometabolic Parameters THOUSAND OAKS, Calif., May 30, 2023 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced new research examining the use of Otezla® (apremilast) in psoriatic arthritis, including the Phase 4 MOSAIC study and an exploratory analysis of cardiometabolic risk factors, which are commonly elevated in patients with psoriatic disease. The findings will be presented at the 2023 European Congress of Rheumatology (EULAR), taking place May 31-June 3 in Milan, Italy. "Research presented at EULAR sheds new light on psoriatic arthritis and the role of our oral medication Otezla," said Ponda Motsepe-Ditshego, vice president, Global Medical at Amgen. "Using MRI, the MOSAIC study visually captured an improvement in inflammation and no significant change in structural progression, with the effects being greater in patients with moderate as opposed to high disease activity." MOSAIC Phase 4 Study Unlike X-ray imaging – commonly used to assess joint damage caused by psoriatic arthritis – MOSAIC used magnetic resonance imaging (MRI), a more sensitive tool for imaging inflammation, which begins early and continues throughout the disease course in joints and entheses (sites where tendons or ligaments attach to bones). MOSAIC evaluated Otezla's effect on joint inflammation and structural progression of psoriatic arthritis measured by MRI. "MOSAIC is the first study to use MRI to assess inflammation in peripheral joints and entheses in a clinical trial, and shows MRI offers a promising way to measure inflammatory disease activity in patients with this condition," said Professor Mikkel Østergaard, M.D., Ph.D., DMSc, Copenhagen Center for Arthritis Research, Center for Rheumatology and Spine Diseases, Rigshospitalet, University of Copenhagen in Copenhagen, Denmark. "The results of this study are encouraging, as they provide important insights about Otezla treatment and its efficacy on both clinical and inflammatory manifestations of psoriatic arthritis." In MOSAIC, a multicenter, single-arm, open-label study, patients with active psoriatic arthritis who were treated with Otezla for 48 weeks had MRI of the hand (contrast-enhanced) performed at baseline, week 24 and week 48. The study evaluated change from baseline in the composite score of hand bone marrow edema (BME), synovitis and tenosynovitis in fingers 2-5, assessed by the psoriatic arthritis MRI score (PsAMRIS) at week 24 (the primary endpoint). Total inflammation score, comprised of BME, synovitis, tenosynovitis and periarticular inflammation in fingers, as well as structural progression, were also assessed. Patients treated with Otezla had improvements in both clinical and MRI measures of inflammation up to week 48. Detailed findings include: Inflammation improved, reflected in the mean change from baseline in the composite inflammation score of BME, synovitis, and tenosynovitis as assessed by PsAMRIS for the full analysis set (n=98), which was -2.32 (-4.73, 0.09) at week 24 and -2.91 (-5.45, -0.37) at week 48. Significant improvements at week 24 and 48 in the per protocol population (n=94) were also observed. No significant structural progression was observed with Otezla. Total damage score – a measure of disease progression – including bone erosion, showed no significant change at weeks 24 and 48. In addition, patients with moderate disease activity as measured by Clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) experienced greater reductions in inflammation with Otezla as compared to those with high disease activity. Common treatment-emergent adverse events were diarrhea (33.6%), nausea (12.3%), headache (10.7%), nasopharyngitis (7.4%) and dyspepsia (6.6%). Findings will be presented Friday, June 2 at 12:10 p.m. CEST: POS0226, Poster Tour Session: Apremilast Reduces Inflammation as Measured by MRI of the Hand in Patients with Psoriatic Arthritis: Primary Results from the Phase 4 MOSAIC Study. Otezla's Effect on Cardiometabolic Parameters in Psoriatic Arthritis A second EULAR presentation includes data evaluating the effects of Otezla on cardiometabolic parameters (low- and high-density lipoprotein [LDL, HDL], body mass index [BMI] and HbA1c levels) in 781 patients with psoriatic arthritis at 52 weeks. The post-hoc exploratory analysis of data from five pooled Phase 3 trials (PALACE 1-4, ACTIVE) showed Otezla treatment was associated with improvement in cardiometabolic parameters across psoriatic disease activity groups. Among the findings reported: Mean LDL in the overall population at baseline decreased by 2.0 mg/dL on average at week 52; 52.3% of patients moved from the high LDL category (≥160 mg/dL) at baseline to borderline (>129 – <160 mg/dL) or normal (≤129 mg/dL) at week 52; and 38.3% changed from borderline high to normal LDL levels. Mean BMI was 30.3 kg/m2 in the overall population at baseline and decreased by 0.5 kg/m2 at week 52; 9.0% of patients changed from the obese category (≥30 kg/m2) to the overweight category (25 – <30 kg/m2) and 12.3% of patients changed from the overweight category to the normal category (<25 kg/m2). 50.4% of patients who had prediabetes changed to normal HbA1c levels and 40.0% moved from diabetes to prediabetes at week 52. Findings will be presented Saturday, June 3 at 10:30 a.m. CEST: POS1527, Poster Session: Effects of Apremilast on Changes in Cardiometabolic Parameters by Diabetes and Obesity Status in Patients with Psoriatic Arthritis. About Psoriatic Arthritis Psoriatic arthritis is a chronic, inflammatory form of arthritis, which can cause swelling, stiffness and pain in and around the joints that worsens over time and can decrease physical function. It is estimated that nearly 38 million people worldwide have psoriatic arthritis.1 Around a third of people living with psoriasis may go on to develop psoriatic arthritis.1 If left untreated, psoriatic arthritis can cause disability. About Otezla® (apremilast) Otezla® (apremilast) is an oral small-molecule inhibitor of phosphodiesterase 4 (PDE4) specific for cyclic adenosine monophosphate (cAMP). PDE4 inhibition results in increased intracellular cAMP levels, which is thought to indirectly modulate the production of inflammatory mediators. The specific mechanism(s) by which Otezla exerts its therapeutic action in patients is not well defined. Since its initial FDA approval in 2014, Otezla has been prescribed to more than 840,000 patients worldwide.2 Otezla® (apremilast) U.S. INDICATIONS INDICATIONS Otezla® (apremilast) is indicated for the treatment of adult patients with plaque psoriasis who are candidates for phototherapy or systemic therapy. Otezla is indicated for the treatment of adult patients with active psoriatic arthritis. Otezla is indicated for the treatment of adult patients with oral ulcers associated with Behçet's Disease. Otezla® (apremilast) U.S. IMPORTANT SAFETY INFORMATION Contraindications Otezla® is contraindicated in patients with a known hypersensitivity to apremilast or to any of the excipients in the formulation Warnings and Precautions Hypersensitivity: Hypersensitivity reactions, including angioedema and anaphylaxis, have been reported during postmarketing surveillance. If signs or symptoms of serious hypersensitivity reactions occur, discontinue Otezla and institute appropriate therapy Diarrhea, Nausea, and Vomiting: Cases of severe diarrhea, nausea, and vomiting were associated with the use of Otezla. Most events occurred within the first few weeks of treatment. In some cases, patients were hospitalized. Patients 65 years of age or older and patients taking medications that can lead to volume depletion or hypotension may be at a higher risk of complications from severe diarrhea, nausea, or vomiting. Monitor patients who are more susceptible to complications of diarrhea or vomiting; advise patients to contact their healthcare provider. Consider Otezla dose reduction or suspension if patients develop severe diarrhea, nausea, or vomiting Depression: Carefully weigh the risks and benefits of treatment with Otezla for patients with a history of depression and/or suicidal thoughts/behavior, or in patients who develop such symptoms while on Otezla. Patients, caregivers, and families should be advised of the need to be alert for the emergence or worsening of depression, suicidal thoughts or other mood changes, and they should contact their healthcare provider if such changes occur Plaque Psoriasis: Treatment with Otezla is associated with an increase in depression. During clinical trials in patients with moderate to severe plaque psoriasis, 1.3% (12/920) of patients reported depression compared to 0.4% (2/506) on placebo. Depression was reported as serious in 0.1% (1/1308) of patients exposed to Otezla, compared to none in placebo-treated patients (0/506). Suicidal behavior was observed in 0.1% (1/1308) of patients on Otezla, compared to 0.2% (1/506) on placebo. One patient treated with Otezla attempted suicide; one patient on placebo committed suicide Psoriatic Arthritis: Treatment with Otezla is associated with an increase in depression. During clinical trials, 1.0% (10/998) reported depression or depressed mood compared to 0.8% (4/495) treated with placebo. Suicidal ideation and behavior was observed in 0.2% (3/1441) of patients on Otezla, compared to none in placebo-treated patients. Depression was reported as serious in 0.2% (3/1441) of patients exposed to Otezla, compared to none in placebo-treated patients (0/495). Two patients who received placebo committed suicide compared to none on Otezla Behçet's Disease: Treatment with Otezla is associated with an increase in depression. During the clinical trial, 1% (1/104) reported depression or depressed mood compared to 1% (1/103) treated with placebo. No instances of suicidal ideation or behavior were reported in patients treated with Otezla or treated with placebo Weight Decrease: Monitor body weight regularly; evaluate unexplained or clinically significant weight loss, and consider discontinuation of Otezla Plaque Psoriasis: Body weight loss of 5-10% occurred in 12% (96/784) of patients with moderate to severe plaque psoriasis treated with Otezla and in 5% (19/382) of patients treated with placebo. Body weight loss of ≥10% occurred in 2% (16/784) of patients treated with Otezla compared to 1% (3/382) of patients treated with placebo Psoriatic Arthritis: Body weight loss of 5-10% was reported in 10% (49/497) of patients taking Otezla and in 3.3% (16/495) of patients taking placebo Behçet's Disease: Body weight loss of >5% was reported in 4.9% (5/103) of patients taking Otezla and in 3.9% (4/102) of patients taking placebo Drug Interactions: Apremilast exposure was decreased when Otezla was co-administered with rifampin, a strong CYP450 enzyme inducer; loss of Otezla efficacy may occur. Concomitant use of Otezla with CYP450 enzyme inducers (e.g., rifampin, phenobarbital, carbamazepine, phenytoin) is not recommended Adverse Reactions Plaque Psoriasis: The most common adverse reactions (≥ 5%) are diarrhea, nausea, upper respiratory tract infection, and headache, including tension headache. Overall, the safety profile of Otezla in patients with mild to moderate plaque psoriasis was consistent with the safety profile previously established in adult patients with moderate to severe plaque psoriasis Psoriatic Arthritis: The most common adverse reactions (≥ 5%) are diarrhea, nausea, and headache Behçet's Disease: The most common adverse reactions (≥ 10%) are diarrhea, nausea, headache, and upper respiratory tract infection. Use in Specific Populations Otezla has not been studied in pregnant women. Advise pregnant women of the potential risk of fetal loss. Please click here for Otezla® Full Prescribing Information.

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. An outbreak of disease or similar public health threat, such as COVID-19, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. 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 collaborate with or acquire other companies, products or technology, and to integrate the operations of companies or to support the products or technology 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 and operations may be negatively affected by the failure, or perceived failure, of achieving our environmental, social and governance objectives. The effects of global climate change and related natural disasters could negatively affect our business and operations. Global economic conditions may magnify certain risks that affect our business. 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.

All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including any statements on the outcome, benefits and synergies of collaborations, or potential collaborations, with any other company (including BeiGene, Ltd., Kyowa Kirin Co., Ltd., or any collaboration to manufacture therapeutic antibodies against COVID-19), the performance of Otezla ® (apremilast) (including anticipated Otezla sales growth and the timing of non-GAAP EPS accretion), the Five Prime Therapeutics, Inc. acquisition, the Teneobio, Inc. acquisition, the ChemoCentryx, Inc. acquisition, or the proposed acquisition of Horizon Therapeutics plc, as well as 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, effects of pandemics or other widespread health problems such as the ongoing COVID-19 pandemic on our business, 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. An outbreak of disease or similar public health threat, such as COVID-19, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. 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 collaborate with or acquire other companies, products or technology, and to integrate the operations of companies or to support the products or technology 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 and operations may be negatively affected by the failure, or perceived failure, of achieving our environmental, social and governance objectives. The effects of global climate change and related natural disasters could negatively affect our business and operations. Global economic conditions may magnify certain risks that affect our business. 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. Any 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 U.S. Food and Drug Administration 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.
