FDA Approves Selarsdi (ustekinumab-aekn), a Biosimilar to Stelara

REYKJAVIK, Iceland & PARSIPPANY, N.J.–(BUSINESS WIRE) April 16, 2024 –Alvotech (NASDAQ: ALVO) and Teva Pharmaceuticals, a U.S. affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA), today announced that the U.S. Food and Drug Administration (FDA) has approved Selarsdi (ustekinumab-aekn) injection for subcutaneous use, as a biosimilar to Stelara, for the treatment of moderate to severe plaque psoriasis and for active psoriatic arthritis in adults and pediatric patients 6 years and older. Under the strategic partnership between Teva and Alvotech, Teva is responsible for the exclusive commercialization of Selarsdi in the United States.

“The approval of Selarsdi – which is our second biosimilar approval this year – underscores Teva’s commitment to expanding the availability, access and uptake of this important treatment option to patients in the U.S.,” said Thomas Rainey, Senior Vice President, U.S. Market Access at Teva. “The biosimilars market is growing, both globally and in the U.S., and biosimilars are a key component of delivering on Teva’s Pivot to Growth strategy. The partnership model that we’ve established enables us to leverage our commercial presence and experiences globally as we move to bring additional biosimilars to market.”

Robert Wessman, Chairman and CEO of Alvotech, added, “We are delighted to announce our second biosimilar approval in the U.S., which is the thirty-eighth approved market for our biosimilar to Stelara globally. Bringing Selarsdi to market in the U.S. early next year presents a significant opportunity to improve patient access to a vital biologic in inflammatory disease and contribute to the reduction of inflationary pressure in healthcare costs. The development of Selarsdi leveraged our purpose-built end-to-end development and manufacturing platform for biosimilars. Being able to develop the biosimilar in the same cell type and continuous perfusion process as was used for the reference product, facilitated the development program’s success.”

Ustekinumab is a human monoclonal antibody (mAb) that selectively targets the p40 protein, a component common to both interleukin (IL)-12 and IL-23 cytokines, which play crucial roles in treating immune-mediated diseases like psoriasis and psoriatic arthritis. Alvotech developed and produces Selarsdi using Sp2/0 cells and a continuous perfusion process, which are the same type of host cell line and process used in the production of Stelara.

Sales of the reference product Stelara in the U.S. were nearly $7 billion in 2023.¹ The availability of a Stelara biosimilar will create opportunities for cost savings across the healthcare system and introduce additional treatment options for patients. In the U.S., plaque psoriasis is the most common form of psoriasis while psoriatic arthritis accounts for approximately six percent of all cases of juvenile arthritis.^2,3

In June 2023, Alvotech and Teva announced that they had reached a settlement and license agreement with the manufacturer of the reference biologic, Johnson & Johnson, granting a license entry date for Selarsdi in the United States no later than February 21, 2025.

In August 2020, Alvotech and Teva entered into a strategic partnership for the exclusive commercialization of five of Alvotech’s biosimilar product candidates, and in August 2023, the collaboration was extended to include two additional biosimilars and new presentations of two previously partnered products. Alvotech handles development and manufacturing, while Teva is responsible for the exclusive commercialization in the U.S., which leverages Teva’s experience and extensive sales and marketing infrastructure. Selarsdi is the second biosimilar approved under the strategic partnership: in February 2024, the FDA approved SIMLANDI®, the first high-concentration, citrate-free biosimilar to Humira that has been granted an interchangeability status by the FDA.

The FDA approval of Selarsdi, referred to as AVT04 during development, was based on a totality of evidence, including analytical and clinical data. The clinical development program included data from: 1) Study AVT04-GL-301, a randomized, double blind, multicenter, 52-week study to demonstrate equivalent efficacy and to compare safety and immunogenicity between Selarsdi and the reference product Stelara in patients with moderate to severe chronic plaque-type psoriasis. The study was conducted in four countries in Europe and enrolled 581 patients. The primary efficacy endpoint was Psoriasis Area and Severity Index (PASI) percent improvement from Baseline to Week 12; 2) Study AVT04-GL-101, a Phase I, randomized, double-blind, single-dose, parallel-group, 3-arm study to compare the pharmacokinetic, safety, tolerability, and immunogenicity profiles of Selarsdi, administered as a single 45mg/0.5mL subcutaneous injection with that of the US-licensed Stelara as well as EU-approved Stelara. The study was conducted in Australia and New Zealand and enrolled 294 healthy adult volunteers.

INDICATIONS

Selarsdi is a human interleukin-12 and -23 antagonist indicated for:

• the treatment of adults and pediatric patients 6 years of age and older with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy.
• the treatment of adults and pediatric patients 6 years of age and older with active psoriatic arthritis.

IMPORTANT SAFETY INFORMATION

Selarsdi injection is contraindicated in patients with clinically significant hypersensitivity to ustekinumab products or to any of the excipients in Selarsdi.

Infections

Ustekinumab products may increase the risk of infections and reactivation of latent infections. Serious bacterial, mycobacterial, fungal, and viral infections were observed in patients receiving ustekinumab products. Serious infections requiring hospitalization, or otherwise clinically significant infections, reported in clinical trials included the following:

• Plague psoriasis: diverticulitis, cellulitis, pneumonia, appendicitis, cholecystitis, sepsis, osteomyelitis, viral infections, gastroenteritis, and urinary tract infections.
• Psoriatic arthritis: cholecystitis.

Avoid initiating treatment with Selarsdi in patients with a clinically important active infection until the infection resolves or is adequately treated. Consider the risks and benefits of treatment prior to initiating use of Selarsdi in patients with a chronic infection or a history of recurrent infection.

Instruct patients to seek medical advice if signs or symptoms suggestive of an infection occur while on treatment with Selarsdi and discontinue Selarsdi for serious or clinically significant infections until the infection resolves or is adequately treated.

Theoretical Risk for Vulnerability to Particular Infections

Individuals genetically deficient in IL-12/IL-23 are particularly vulnerable to disseminated infections from mycobacteria (including nontuberculous, environmental mycobacteria), salmonella (including non typhi strains), and Bacillus Calmette-Guerin (BCG) vaccinations. Serious infections and fatal outcomes have been reported in such patients.

It is not known whether patients with pharmacologic blockade of IL-12/IL-23 from treatment with ustekinumab products may be susceptible to these types of infections. Consider appropriate diagnostic testing, (e.g., tissue culture, stool culture as dictated by clinical circumstances).

Pre-Treatment Evaluation of Tuberculosis (TB)

Evaluate patients for tuberculosis prior to initiating treatment with Selarsdi.

Avoid administering Selarsdi to patients with active tuberculosis infection. Initiate treatment of latent tuberculosis before administering Selarsdi. Consider anti-tuberculosis therapy prior to initiation of Selarsdi in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed. Closely monitor patients receiving Selarsdi for signs and symptoms of active tuberculosis during and after treatment.

Malignancies

Ustekinumab products are immunosuppressants and may increase the risk of malignancy. Malignancies were reported among patients who received ustekinumab in clinical trials. In rodent models, inhibition of IL-12/IL-23p40 increased the risk of malignancy.

The safety of ustekinumab products has not been evaluated in patients who have a history of malignancy or who have a known malignancy.

There have been post-marketing reports of the rapid appearance of multiple cutaneous squamous cell carcinomas in patients receiving ustekinumab products who had pre-existing risk factors for developing non-melanoma skin cancer. Monitor all patients receiving Selarsdi should be monitored for the appearance of non-melanoma skin cancer. Closely follow patients greater than 60 years of age, those with a medical history of prolonged immunosuppressant therapy and those with a history of PUVA treatment.

Hypersensitivity Reactions

Hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with ustekinumab products. If an anaphylactic or other clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue Selarsdi.

Posterior Reversible Encephalopathy Syndrome (PRES)

Two cases of posterior reversible encephalopathy syndrome (PRES), also known as Reversible Posterior Leukoencephalopathy Syndrome (RPLS), were reported in clinical trials. Cases have also been reported in postmarketing experience in patients with psoriasis and psoriatic arthritis. Clinical presentation included headaches, seizures, confusion, visual disturbances, and imaging changes consistent with PRES a few days to several months after ustekinumab product initiation. A few cases reported latency of a year or longer. Patients recovered with supportive care following withdrawal of ustekinumab products.

Monitor all patients treated with Selarsdi for signs and symptoms of PRES. If PRES is suspected, promptly administer appropriate treatment and discontinue Selarsdi.

Immunizations

Prior to initiating therapy with Selarsdi, patients should receive all age-appropriate immunizations as recommended by current immunization guidelines. Patients being treated with Selarsdi should avoid receiving live vaccines. Avoid administering BCG vaccines during treatment with Selarsdi or for one year prior to initiating treatment or for one year following discontinuation of treatment. Caution is advised when administering live vaccines to household contacts of patients receiving Selarsdi because of the potential risk for shedding from the household contact and transmission to patient.

Non-live vaccinations received during a course of Selarsdi may not elicit an immune response sufficient to prevent disease.

Noninfectious Pneumonia

Cases of interstitial pneumonia, eosinophilic pneumonia, and cryptogenic organizing pneumonia have been reported during post-approval use of ustekinumab products. Clinical presentations included cough, dyspnea, and interstitial infiltrates following one to three doses. Serious outcomes have included respiratory failure and prolonged hospitalization. Patients improved with discontinuation of therapy and in certain cases administration of corticosteroids. If diagnosis is confirmed, discontinue Selarsdi and institute appropriate treatment.

ADVERSE REACTIONS

The following serious adverse reactions are discussed elsewhere in the label:

• Infections
• Malignancies
• Hypersensitivity Reactions
• Posterior Reversible Encephalopathy Syndrome (PRES)
• Noninfectious Pneumonia
