Argenx Releases H1 2025 Financials and Q2 Business Highlights
Argenx, a global immunology company dedicated to improving the lives of people suffering from severe autoimmune diseases, has published its first-half 2025 financial results and second-quarter business highlights. The company’s robust pipeline development and strategic partnerships continue to shape its position as a biotech leader in rare diseases.
Strong Revenue Growth Driven by Vyvgart Franchise
Argenx reported total revenues of $949 million in the first half of 2025, reflecting an impressive year-over-year increase. The growth was mainly fueled by strong global sales of Vyvgart (efgartigimod), the company’s flagship treatment for generalized myasthenia gravis (gMG). Vyvgart continues to perform well in both the U.S. and international markets, backed by increasing patient demand and healthcare provider adoption.
In the second quarter alone, Vyvgart generated $491 million, accounting for over half of the total revenue. This strong performance underlines the product’s clinical value and commercial success in multiple territories, including the U.S., Europe, Japan, and China. The SC (subcutaneous) version, Vyvgart Hytrulo, has also gained momentum since its approval, further expanding treatment options for patients.
Argenx Expands Clinical Pipeline
Beyond Vyvgart, Argenx is progressing rapidly in expanding its clinical pipeline. The company now has three molecules in late-stage development, including:
- efgartigimod in additional autoimmune indications such as chronic inflammatory demyelinating polyneuropathy (CIDP), primary immune thrombocytopenia (ITP), and pemphigus.
- ARGX-117, targeting complement-mediated diseases, is currently in Phase 2 trials.
- ARGX-119, being developed for neurodegenerative conditions, is now moving into clinical evaluation.
Argenx’s strategy includes not just broadening indications for efgartigimod but also developing entirely new assets that address high unmet needs in the autoimmune space. Health Canada approved Vyvgart SC for the treatment of adult gMG patients, marking a major step in the North American market.
Business Milestones in Q2 2025
During the second quarter of 2025, Argenx achieved multiple key business milestones:
- Regulatory Approval in Canada: Health Canada approved Vyvgart SC for the treatment of adult gMG patients, marking a major step in the North American market.
- New Partnership in China: The company expanded its collaboration with Zai Lab, a key pharmaceutical partner, to accelerate access to Vyvgart in Asia.
- Enrollment Completed: Phase 3 trials for CIDP completed patient enrollment, with top-line results expected by Q4 2025.
Argenx also made significant strides in building commercial infrastructure in emerging markets and streamlining its supply chain to meet increasing demand.
R&D Investment and Operational Focus
Argenx remains committed to reinvesting revenues into research and development. In Argenx H1 2025, R&D expenses reached $446 million, representing its commitment to advancing transformative treatments. The company’s total operating loss stood at $83 million, reflecting heavy front-loaded investments into clinical trials and manufacturing scale-up.
The company’s management maintains a disciplined approach to spending while balancing strategic expansion. Argenx holds a strong cash position of $2.3 billion, enabling it to support its next phase of growth and innovation.
Global Expansion of Vyvgart
Vyvgart’s success is not limited to the United States. The treatment is now available in over 30 countries, with more regulatory submissions underway. Market penetration is steadily improving in Europe, especially in Germany, the Netherlands, and the UK. Japan and China have also shown promising uptake thanks to favorable reimbursement environments.
Argenx’s strategic goal is to make Vyvgart accessible to all eligible gMG patients globally. Continued education, patient support programs, and collaborations with patient advocacy groups remain central to their expansion strategy.
Guidance for Remainder of 2025
Looking ahead, Argenx is confident in achieving full-year revenue growth in the double digits. Continued focus will be on:
- Clinical readouts from pivotal trials
- Expanding indications for Vyvgart
- Strengthening partnerships and commercial access
- Advancing preclinical assets
The company aims to become a fully integrated immunology business with a broad therapeutic footprint and scalable infrastructure.
