AMGEN ANNOUNCES NEW OTEZLA (APREMILAST) DATA AT AAD CONGRESS 2022

New data further reinforces clinical benefit of Otezla in mild to moderate plaque psoriasis and in patients with palmoplantar pustulosis

Real-world evidence data being presented demonstrates continued burden of disease for patients with mild to moderate plaque psoriasis

Otezla is the first and only oral therapy FDA approved in adult patients with plaque psoriasis across all severities, including mild, moderate and severe

THOUSAND OAKS, Calif., March 25, 2022 /PRNewswire/ -- Amgen (NASDAQ: AMGN) today announced that new Otezla (apremilast) data, along with findings on the unmet need for patients with plaque psoriasis, will be presented at the American Academy of Dermatology (AAD) congress in Boston, Massachusetts, March 25-29, 2022. These data presentations follow the recent U.S. Food and Drug Administration (FDA) expanded Otezla label approval in December 2021.

"The data being presented at AAD demonstrates Amgen's continued commitment to supporting patients that are living with plaque psoriasis – especially those affected in difficult-to-treat areas as well as those with palmoplantar pustulosis – and understanding the unmet needs they continue to face," said Primal Kaur, vice president, Global Development, Inflammation at Amgen. "With Otezla's recently expanded label that enables us to reach plaque psoriasis patients across all levels of disease severity, Amgen is now able to offer a treatment that could help to alleviate the significant burden on these patients"

Amgen will present data from a Phase 2 palmoplantar pustulosis (PPP) Japanese trial (PPP-001) as well as data from both the PROMINENT and ADVANCE Phase 3 studies in patients with mild to moderate plaque psoriasis. Results from the PPP-001 trial showed that apremilast demonstrated meaningful and early improvements in PPP severity, itching and pain, and that adverse events (the most common including gastrointestinal events and headache) were consistent with the known safety profile. The PROMINENT and ADVANCE studies reinforced the efficacy of apremilast in patients with mild to moderate plaque psoriasis.

Additionally, results from the multinational UPLIFT survey and real-world CorEvitas' Psoriasis registry continue to highlight the ongoing impact and unmet needs in patients with mild to moderate plaque psoriasis especially those with special area involvement. Both will be shared as oral presentations on Sunday, March 27, 2022, from 10:35am – 10:40am ET and 10:25am – 10:30am ET, respectively.

Otezla is approved for three indications in the U.S., including adult patients with plaque psoriasis who are candidates for phototherapy or systemic therapy, adult patients with active psoriatic arthritis and for adult patients with oral ulcers associated with Behçet's Disease. Otezla is the most prescribed brand for plaque psoriasis patients starting systemic therapy.¹ Amgen is committed to investigating the potential of Otezla across the continuum of psoriasis, including underserved patients with genital psoriasis, pediatric psoriasis, juvenile psoriatic arthritis and other areas of high burden.

About PPP-001 PH2 Trial
Palmoplantar pustulosis (PPP) is a pruritic, painful and debilitating chronic dermatitis, characterized by recurrent eruptions of pustules on the palms and soles. Approved therapeutic options are limited. This randomized, phase 2 study (NCT04057937) evaluated apremilast 30 mg twice daily for efficacy and safety vs placebo (PBO) for moderate to severe PPP after inadequate response to topical therapy in Japan.

The primary endpoint was ≥50% improvement in PPP Area and Severity Index (PPPASI-50; chi-square, α=0.10) at Week 16.

About PROMINENT
PROMINENT (NCT03930186) is  Phase 3b, multicenter, open-label, single-arm study evaluating the efficacy and safety of apremilast in Japanese patients with mild to moderate plaque psoriasis (Static Physician's Global Assessment (sPGA) score of 2 to 3) not adequately controlled by topical therapy. The study recruited 152 patients to receive apremilast 30 mg twice daily for 32 weeks on top of their existing topical therapy.

The primary endpoint was percentage of patients who achieved an sPGA score of 0 or 1 at week 16.

About ADVANCE (PSOR-022)
ADVANCE (NCT03721172) is a Phase 3, multicenter, randomized, placebo-controlled, double-blind study evaluating the efficacy and safety of apremilast in patients with mild to moderate plaque psoriasis (defined as Body Surface Area involvement of 2% to 15%, Psoriasis Area and Severity Index (PASI) score of 2 to 15, sPGA score of 2 to 3). The study randomized 595 patients 1:1 to receive apremilast (n=297) 30 mg twice daily or placebo (n=298) for the first 16 weeks. All patients then received apremilast during an open-label extension phase through week 32.

The primary endpoint was the percentage of patients with sPGA response [defined as a sPGA score of clear (0) or almost clear (1) with at least a 2-point reduction from baseline] at week 16.

About the UPLIFT Survey
In 2020, Amgen conducted the global Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) survey exploring the evolution of attitudes and behaviors of 3,806 people living with psoriasis and psoriatic arthritis, 473 dermatologists and 450 rheumatologists in eight countries in North America, Europe and Asia. The survey was conducted in 2020 and was overseen by an academic steering committee of thought-leaders in dermatology and rheumatology. The survey builds upon findings from the 2012 Multinational Assessment of Psoriasis and Psoriatic Arthritis (MAPP) survey, a first-of-its-kind study conducted by Celgene that looked in-depth at the effect of psoriasis and psoriatic arthritis on people living with these conditions.  

About Psoriasis
Psoriasis is a serious, chronic inflammatory disease that causes raised, red, scaly patches to appear on the skin, typically affecting the outside of the elbows, knees or scalp, though it can appear on any location.² Approximately 125 million people worldwide have psoriasis, including around 14 million people in Europe and more than 7.5 million people in the United States.^3,4 About 80% of those patients have plaque psoriasis.⁵

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.

Otezla^® (apremilast) U.S. INDICATIONS

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

• 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.

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 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, or the Teneobio, Inc. acquisition, 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.

The scientific information discussed in this news release related to our product candidates is preliminary and investigative. Such product candidates are not approved by the U.S. Food and Drug Administration, and no conclusions can or should be drawn regarding the safety or effectiveness of the product candidates. Further, 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.
