Significant Growth Expected in Antibody-Mediated Rejection Market by 2034 Driven by New Therapeutics

Expansion of the Antibody-Mediated Rejection Market

The antibody-mediated rejection (AMR) market is poised for substantial growth from 2025 to 2034, driven by a rising number of organ transplants and enhanced awareness of AMR's crucial impact on graft survival. According to insights from DelveInsight, significant advancements in diagnostics, including improved assays and biomarkers, alongside emerging targeted therapies, are fundamentally shifting the landscape of AMR treatment.

Market Overview

In 2024, the United States accounted for the largest segment of the AMR treatment market in the seven major markets (7MM), which includes the US, EU4 (Germany, France, Italy, Spain), the UK, and Japan. The anticipated increase in transplant cases—estimated at approximately 55,000 in the US—highlights the urgency for innovative AMR therapies.

The report sheds light on many promising drugs in clinical trials such as Felzartamab (developed by Biogen), Imlifidase (by Hansa Biopharma), Riliprubart (from Sanofi), Efgartigimod PH20 SC (by argenx), and ALXN2030 (by AstraZeneca). As these drugs advance toward regulatory approval, they hold the potential to reshape treatment protocols significantly.

Driving Factors of Market Growth

1. Rising Transplant Cases

The increase in organ transplants correlates with the growing incidence of AMR, which emphasizes the need for enhanced diagnostics and innovative treatment approaches. Furthermore, better monitoring of transplanted organs through biomarkers is becoming critical, as traditional methods often yield insufficient results.

2. Diagnostic Advancements

Modern diagnostic tools, such as high-resolution anti-HLA and DSA testing, along with cell-free DNA analyses, have improved the precision and timing of AMR detection. These advancements facilitate timely interventions and the deployment of more effective therapies, establishing a vital market for companion diagnostics.

3. Emergence of Novel Therapeutics

Several companies are actively pursuing the development of drugs that target various aspects of AMR. Felzartamab has demonstrated potential in providing disease-modifying effects for late AMR, as indicated by promising results shown in Phase II trials. The need for a safer and more effective remedy in this arena has never been more apparent, underscoring the importance of these new therapeutic options.

Current Treatment Landscape

Initially, AMR management primarily relied on immunosuppressive techniques, plasmapheresis, intravenous immunoglobulin therapy, and complement inhibitors. However, given the limitations of these treatments—including their inability to prevent chronic rejection—there is an urgent demand for more efficacious therapies.

Currently, there are no FDA-approved medications expressly for AMR, presenting a significant barrier in the field of transplant medicine. Patients continue to suffer consequences due to the lack of substantial clinical trials that focus on improving AMR treatment outcomes, exacerbating the need for innovative solutions.

Market Challenges

Despite the plethora of emerging therapies, challenges lie ahead. Notably, Talaris Therapeutics has scrapped the FREEDOM-1 and FREEDOM-2 kidney transplant trials due to poor participant recruitment, while clazakizumab's development ceased following the failure of its Phase III IMAGINE trial. These setbacks highlight the complexities of advancing AMR treatments efficiently.

Competitive Landscape

The competitive landscape is evolving, with several new entrants introducing promising therapies to the market. The anticipation surrounding innovative therapies like Felzartamab, Imlifidase, and Riliprubart offers hope for transforming AMR management. Biogen's Felzartamab is under clinical evaluation and is touted as a breakthrough in targeting CD38, which could provide substantial treatment benefits across a range of immune-mediated disorders.

Conclusion

In summary, the antibody-mediated rejection market is on the verge of a significant transformation, propelled by advancements in diagnostic techniques and the introduction of innovative therapeutics. As the market evolves and companies continue to invest in research and development, a new standard of care may emerge, enhancing the prognosis for transplant recipients facing AMR challenges.
