Rationale for the IMAGINE study for chronic active antibody-mediated rejection (caAMR) in kidney transplantation

Area of Science:

• Nephrology
• Transplantation Immunology
• Immunosuppression

Background:

• Chronic active antibody-mediated rejection (caAMR) is a primary driver of late kidney transplant loss.
• Current therapeutic options for caAMR are limited, with no proven effective treatments.
• The Transplant Society (TTS) recommends optimizing baseline immunosuppression and supportive care for caAMR management.

Approach:

• This review discusses the rationale and early evidence supporting the IMAGINE study.
• The IMAGINE study aims to evaluate the impact of targeting the IL6/IL6R pathway.
• Investigating the IL6/IL6R pathway offers a novel therapeutic strategy for caAMR.

Key Points:

• caAMR poses a significant threat to long-term kidney allograft survival.
• The lack of effective therapies necessitates novel treatment approaches.
• Targeting the IL6/IL6R pathway is being explored as a potential intervention.

Conclusions:

• The IMAGINE study is designed to assess the efficacy of IL6/IL6R pathway inhibition in caAMR.
• Early evidence supports the investigation of this pathway as a therapeutic target.
• Further research is crucial to establish effective treatments for caAMR.
