Biogen's Felzartamab Enters Phase 3: Targeting Kidney Transplant Rejection#
TRANSCEND Trial Design: Efficacy and Safety Evaluation#
Biogen has initiated the TRANSCEND Phase 3 clinical trial to assess felzartamab's efficacy in treating late antibody-mediated rejection (AMR) in kidney transplant patients. This trial signifies a strategic move to broaden Biogen's pipeline beyond its traditional focus areas, addressing a critical unmet need in transplant medicine. The global study aims to enroll approximately 120 adult kidney transplant recipients diagnosed with late AMR and will evaluate felzartamab against a placebo (Biogen's Press Release on Felzartamab Phase 3 Trial).
Felzartamab's qualification as potentially "first-in-class" and "disease-modifying," based on Phase 2 results, underscores its promising clinical outlook and aligns with Biogen's strategy to diversify its portfolio and address unmet medical needs in specialized therapeutic areas. This development could potentially open a new avenue for growth in the pharmaceutical industry.
Antibody-Mediated Rejection (AMR): A Critical Unmet Need#
Late antibody-mediated rejection (AMR) is a significant complication following kidney transplantation, leading to graft dysfunction and eventual failure. The absence of approved therapies underscores the urgent need for innovative treatments like felzartamab. AMR affects approximately 23,000 patients in the U.S. and is a leading cause of kidney transplant loss. Existing treatments are based on consensus, with limited efficacy in altering long-term outcomes. Biogen plans to initiate Phase 3 trials for felzartamab in IgA nephropathy and primary membranous nephropathy in 2025, expanding its potential market.
Given the lack of effective treatments and the growing number of patients affected by AMR, felzartamab represents a potential breakthrough in improving the long-term outcomes for kidney transplant recipients. This strategic move aligns with Biogen's broader focus on addressing unmet medical needs and diversifying its revenue streams.

Leqembi's European Approval: Navigating Regulatory Hurdles#
Leqembi's US Performance: A Comparison#
The EU regulatory landscape surrounding Leqembi, Biogen's Alzheimer's treatment developed with Eisai, has been marked by uncertainty. While the Committee for Medicinal Products for Human Use (CHMP) reaffirmed its positive opinion for Leqembi in February 2025, earlier setbacks, including a negative opinion in July 2024, have created challenges for its market entry (Reuters on Leqembi EU Regulatory Status). In November 2024, CHMP issued a positive opinion in a restricted Alzheimer's population.
Slow uptake in the US, coupled with regulatory challenges in the EU and Australia, prompted Eisai to reduce its full-year sales forecast for Leqembi. However, sales of Leqembi increased steadily over 2024. Leqembi achieved sales of €200 million, triggering a €10 million payment to BioArctic. The US is expected to contribute the most to Leqembi's sales. The approval and subsequent market penetration of Leqembi in Europe will be crucial for Biogen's revenue forecasts for Alzheimer's treatments.
