Insights

Pharmaceutical Market Analyst

This strategic partnership between Samsung Bioepis and Teva for EPYSQLI® represents a significant market opportunity in the rare disease space. The original drug Soliris® generated $3.4 billion in sales in 2023, making this biosimilar commercialization agreement particularly valuable. The rare disease market typically maintains higher pricing power and patient retention compared to other therapeutic areas.

The deal strengthens Teva's position in the $28.2 billion U.S. biosimilars market, complementing their existing portfolio of 18 assets. For context, biosimilars can typically capture 30-50% of the reference product's market share within 2-3 years while offering 20-30% price discounts, suggesting substantial revenue potential for Teva.

Samsung Bioepis' established manufacturing infrastructure and successful track record with 9 biosimilars across 40 countries significantly reduces execution risk. The existing commercial availability in Europe and Korea provides valuable real-world evidence to support U.S. market adoption.

Healthcare Policy Expert

The introduction of EPYSQLI® addresses a critical healthcare access issue in the rare disease space. The reference product Soliris® has been one of the world's most expensive drugs, with annual treatment costs exceeding $500,000 per patient. This biosimilar entry could potentially reduce treatment costs by 20-30%, expanding access for the estimated 8,000-10,000 PNH patients in the U.S.

The timing is particularly strategic as healthcare payers are increasingly focused on specialty drug cost containment. The expanded indication for gMG, which affects approximately 20,000 patients in the U.S., provides additional market opportunity and potential cost savings for the healthcare system. The partnership's success in Europe since July 2023 provides a blueprint for U.S. market access strategies and payer negotiations.

Clinical Research Analyst

The FDA approval across three rare disease indications - PNH, aHUS and gMG - demonstrates the robust clinical equivalence of EPYSQLI® to Soliris®. The sequential approval pattern, with gMG indication added in November 2024, mirrors the reference product's development path and suggests strong clinical data package. The established safety and efficacy profile in Europe and Korea since 2023 provides additional confidence in the product's clinical performance.

For patients, the biosimilar maintains the same dosing regimen and mechanism of action as Soliris®, targeting C5 complement protein to reduce complement-mediated hemolysis in PNH and thrombotic microangiopathy in aHUS. The proven interchangeability in these complex molecular pathways is particularly noteworthy given the critical nature of these rare diseases.

• Marks a step forward in broadening treatment options for patients with paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS) and generalized myasthenia gravis (gMG) in the U.S.
• Partnership supports Teva's Pivot to Growth strategy and adds to its broad biosimilar portfolio

INCHEON, Korea and TEL AVIV, Israel, Jan. 10, 2025 (GLOBE NEWSWIRE) -- Samsung Bioepis Co., Ltd. and Teva Pharmaceutical Industries Ltd. (NYSE: and TASE: TEVA) announced today that the companies have entered into a license, development and commercialization agreement for EPYSQLI^® (eculizumab-aagh), Samsung Bioepis’ biosimilar to Soliris^®i (eculizumab-aagh) in the United States (U.S.).

SELECTED SAFETY INFORMATION

WARNING: SERIOUS MENINGOCOCCAL INFECTIONS

See full prescribing information for complete boxed warning.

Eculizumab products, complement inhibitors, increase the risk of serious infections caused by Neisseria meningitidis. Life-threatening and fatal meningococcal infections have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early.

Complete or update vaccination for meningococcal bacteria (for serogroups A, C, W, Y, and B) at least 2 weeks prior to the first dose of EPYSQLI, unless the risks of delaying therapy with EPYSQLI outweigh the risk of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations against meningococcal bacteria in patients receiving a complement inhibitor. Patients receiving eculizumab products are at increased risk for invasive disease caused by Neisseria meningitidis, even if they develop antibodies following vaccination. Monitor patients for early signs and symptoms of serious meningococcal infections and evaluate immediately if infection is suspected.

Because of the risk of serious meningococcal infections, EPYSQLI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called EPYSQLI REMS.

CONTRAINDICATIONS

EPYSQLI is contraindicated for initiation in patients with unresolved serious Neisseria meningitidis infection.

WARNINGS AND PRECAUTIONS

Serious Meningococcal Infections

Eculizumab products, complement inhibitors, increase a patient's susceptibility to serious, life-threatening, or fatal infections caused by meningococcal bacteria (septicemia and/or meningitis) in any serogroup, including non-groupable strains. Life-threatening and fatal meningococcal infections have occurred in both vaccinated and unvaccinated patients treated with complement inhibitors. The initiation of EPYSQLI treatment is contraindicated in patients with unresolved serious Neisseria meningitidis infection.

Complete or update meningococcal vaccination (for serogroups A, C, W, Y, and B) at least 2 weeks prior to administration of the first dose of EPYSQLI, according to current ACIP recommendations for patients receiving a complement inhibitor. Revaccinate patients in accordance with ACIP recommendations, considering the duration of therapy with EPYSQLI. Note that ACIP recommends an administration schedule in patients receiving complement inhibitors that differs from the administration schedule in the vaccine prescribing information. If urgent EPYSQLI therapy is indicated in a patient who is not up to date with meningococcal vaccines according to ACIP recommendations, provide the patient with antibacterial drug prophylaxis and administer meningococcal vaccines as soon as possible. Various durations and regimens of antibacterial drug prophylaxis have been considered, but the optimal durations and drug regimens for prophylaxis and their efficacy have not been studied in unvaccinated or vaccinated patients receiving complement inhibitors, including eculizumab products. The benefits and risks of treatment with EPYSQLI, as well as the benefits and risks of antibacterial drug prophylaxis in unvaccinated or vaccinated patients, must be considered against the known risks for serious infections caused by Neisseria meningitidis.

Vaccination does not eliminate the risk of serious meningococcal infections, despite development of antibodies following vaccination.

Closely monitor patients for early signs and symptoms of meningococcal infection and evaluate patients immediately if infection is suspected. Inform patients of these signs and symptoms and instruct patients to seek immediate medical care if these signs and symptoms occur. Promptly treat known infections. Meningococcal infection may become rapidly life- threatening or fatal if not recognized and treated early. Consider interruption of EPYSQLI in patients who are undergoing treatment for serious meningococcal infection, depending on the risks of interrupting treatment in the disease being treated.

EPYSQLI is available only through a restricted program under a REMS called EPYSQLI REMS, because of the risk of serious meningococcal infections.

Other Infections

Serious infections with Neisseria species (other than Neisseria meningitidis), including disseminated gonococcal infections, have been reported.

Eculizumab products block terminal complement activation; therefore, patients may have increased susceptibility to infections, especially with encapsulated bacteria, such as infections with Neisseria meningitidis but also Streptococcus pneumoniae, Haemophilus influenzae, and to a lesser extent, Neisseria gonorrhoeae. Additionally, Aspergillus infections have occurred in immunocompromised and neutropenic patients. Children treated with eculizumab products may be at increased risk of developing serious infections due to Streptococcus pneumoniae and Haemophilus influenzae type b (Hib). Administer vaccinations for the prevention of Streptococcus pneumoniae and Haemophilus influenzae type b (Hib) infections according to ACIP recommendations. Patients receiving eculizumab products are at increased risk for infections due to these organisms, even if they develop antibodies following vaccination.

Monitoring Disease Manifestations after EPYSQLI Discontinuation

Treatment Discontinuation for PNH
Monitor patients after discontinuing EPYSQLI for at least 8 weeks to detect hemolysis.

Treatment Discontinuation for aHUS
After discontinuing EPYSQLI, monitor patients with aHUS for signs and symptoms of thrombotic microangiopathy (TMA) complications for at least 12 weeks. In aHUS clinical trials, 18 patients (5 in the prospective studies) discontinued eculizumab treatment. TMA complications occurred following a missed dose in 5 patients, and eculizumab was reinitiated in 4 of these 5 patients.

Clinical signs and symptoms of TMA include changes in mental status, seizures, angina, dyspnea, or thrombosis. In addition, the following changes in laboratory parameters may identify a TMA complication: occurrence of two, or repeated measurement of any one of the following: a decrease in platelet count by 25% or more compared to baseline or the peak platelet count during EPYSQLI treatment; an increase in serum creatinine by 25% or more compared to baseline or nadir during EPYSQLI treatment; or, an increase in serum LDH by 25% or more over baseline or nadir during EPYSQLI treatment.

If TMA complications occur after EPYSQLI discontinuation, consider reinstitution of EPYSQLI treatment, plasma therapy [plasmapheresis, plasma exchange, or fresh frozen plasma infusion (PE/PI)], or appropriate organ-specific supportive measures.

Thrombosis Prevention and Management

The effect of withdrawal of anticoagulant therapy during eculizumab products treatment has not been established. Therefore, treatment with eculizumab products should not alter anticoagulant management.

Infusion-Related Reactions

Administration of eculizumab products may result in infusion-related reactions, including anaphylaxis or other hypersensitivity reactions. In clinical trials, no patients experienced an infusion-related reaction which required discontinuation of eculizumab. Interrupt EPYSQLI infusion and institute appropriate supportive measures if signs of cardiovascular instability or respiratory compromise occur.

ADVERSE REACTIONS

The most frequently reported adverse reactions in the PNH randomized trial (≥10% overall and greater than placebo) are: headache, nasopharyngitis, back pain, and nausea.

The most frequently reported adverse reactions in aHUS single arm prospective trials (≥20%) are: headache, diarrhea, hypertension, upper respiratory infection, abdominal pain, vomiting, nasopharyngitis, anemia, cough, peripheral edema, nausea, urinary tract infections, pyrexia.

The most frequently reported adverse reaction in the gMG placebo-controlled clinical trial (≥10%) is: musculoskeletal pain.
