Sandoz files antitrust litigation against Amgen regarding patient access to etanercept biosimilar in the US

/EIN News/ -- Ad hoc announcement pursuant to art. 53 SIX Swiss Exchange Listing Rules

• Company aims to accelerate access to much-needed biosimilar to reference medicine Enbrel®^* for US patients with disabling inflammatory diseases
• Despite FDA approval nearly a decade ago, etanercept biosimilar continues to be blocked
• Sandoz seeking damages in addition to clearing path for launch
  
  

Basel, April 14, 2025 – Sandoz (SIX:SDZ/OTCQX:SDZNY), the global leader in generic and biosimilar medicines, today announced the filing of an antitrust lawsuit in the US against Amgen, Inc. (Amgen), for extending and entrenching the dominant market position of its blockbuster medicine, Enbrel® (etanercept), first approved by the US Food and Drug Administration (FDA) in 1998.

Etanercept is a biologic medicine used to treat a range of disabling inflammatory diseases. Sandoz alleges that Amgen blocked competition from more cost-effective biosimilar competitors, including Sandoz etanercept biosimilar, Erelzi®+ (etanercept-szzs), by unlawfully purchasing and using certain patent rights to entrench its position in the market. In 2024, Enbrel® generated USD 3.3 billion in revenue in the US[1].

Sandoz received US FDA approval for Erelzi® in 2016, the same year the company launched the medicine in Europe. Today, Amgen is continuing to block entry of this important treatment option for approximately 7.5 million Americans living with chronic inflammatory diseases, including rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis and juvenile idiopathic arthritis[2-6], many of whom could benefit from the cost savings and expanded access resulting from the introduction of high-quality, more-affordable biosimilar options.

Sandoz is seeking an injunction to prevent Amgen from using certain patent rights to block biosimilar competition and allow Sandoz to launch Erelzi® as soon as possible. The company is also seeking damages, which could be tripled under applicable laws. The lawsuit was filed in the US District Court for the Eastern District of Virginia.

About Erelzi® (etanercept-szzs)
Erelzi® is the Sandoz biosimilar of the reference medicine Enbrel®. Erelzi® has been studied in a global development program, which included a comprehensive comparison of Erelzi® and Enbrel® at the analytical, preclinical, and clinical levels. The program included preclinical studies, pharmacokinetic (PK) studies, and the Phase III confirmatory safety and efficacy EGALITY study. Erelzi® is approved by the US FDA for the following indications: adult rheumatoid arthritis (RA), ankylosing spondylitis (AS), polyarticular juvenile idiopathic arthritis (JIA), psoriatic arthritis (PsA) and moderate to severe plaque psoriasis (PsO).
