Felzartamab’s 1.5-hour administration time is a major convenience upgrade over Darzalex’s 7-hour intravenous infusion, though Janssen’s 3–5 minute subcutaneous Darzalex Faspro formulation is currently in clinical trials in China, with Biogen Inc.

Expert Insights

Biogen’s felzartamab deal is a low-risk, targeted move to diversify its oncology and rare disease portfolio, offsetting expected slowing revenue growth from its Alzheimer’s disease franchise as competing therapies enter the global market. The Chinese r/r MM market remains significantly underpenetrated, with anti-CD38 utilization rates trailing those of the U.S. and EU by nearly 20 percentage points as of 2025, leaving material room for adoption expansion over the next 5 years. The domestic manufacturing designation is felzartamab’s core competitive moat: public hospital tenders, which drive approximately 65% of all pharmaceutical sales in China, give preferential weighting to locally produced drugs under VBP rules, which would allow Biogen to undercut the price of imported Darzalex while maintaining healthy gross margins. That said, meaningful execution risks remain. The largest near-term headwind is the potential NMPA approval of Janssen’s Darzalex Faspro, whose 3–5 minute administration time and possible home use designation would eliminate felzartamab’s current convenience advantage, forcing Biogen to compete solely on pricing and policy support. Additionally, prescriber loyalty to Darzalex is high: the first-in-class therapy held 87.5% of global anti-CD38 sales in 2025, with $7.1 billion in annual revenue, and has a well-documented real-world efficacy track record that felzartamab will need to match with published Phase III data to drive uptake. From a financial perspective, the deal’s largely milestone-driven payment structure limits Biogen’s downside risk, with less than 20% of the total $850 million commitment allocated to upfront payment, per unconfirmed industry sources. If felzartamab hits its projected 14.6% 2029 China market share, it would generate roughly $67 million in annual regional revenue for Biogen, with incremental upside from global launches. While the asset is not expected to be transformative to Biogen’s top line in the medium term, it provides a strategic entry into China’s fast-growing oncology segment. It remains to be seen if felzartamab’s domestic policy advantages are sufficient to mount a credible challenge to Darzalex’s incumbent leadership, and we maintain our neutral rating on BIIB shares pending further regulatory and clinical updates.
