Belatacept in Solid Organ Transplantation: Current Kidney Applications, Future Perspectives in Other Organs, and Clinical Implications.
Review in Pharmaceuticals (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Belatacept, a selective costimulation blocker targeting the CD28-CD80/86 pathway, represents a major innovation in solid organ transplantation immunosuppression. By providing upstream inhibition of T-cell activation without calcineurin inhibition, belatacept offers the potential for improved long-term graft and patient outcomes with reduced nephrotoxicity and metabolic adverse effects. This review summarizes the mechanistic rationale, pivotal evidence, and clinical experience supporting the use of belatacept as first-line or conversion therapy in solid organ transplantation, while addressing safety, pharmacoeconomic impact, and future research directions. A comprehensive analysis of pivotal phase II-III trials (BENEFIT, BENEFIT-EXT), recent prospective conversion studies, and ongoing trials in liver, heart, and lung transplantation was performed. Safety data and health-economic evaluations were critically appraised. In kidney transplantation, belatacept-based immunosuppression provides superior renal function and improved metabolic profiles compared with calcineurin inhibitors (CNIs), though with higher early acute rejection rates. In liver, heart, and lung transplantation, evidence remains limited, with de novo use contraindicated in liver grafts due to excess mortality and rejection. Conversion from CNI to belatacept in selected patients improves renal outcomes without compromising graft survival. Safety considerations include a higher risk of post-transplant lymphoproliferative disorder (PTLD) in Epstein-Barr virus-negative recipients. Belatacept represents a paradigm shift in transplant immunology by targeting upstream T-cell activation. While currently approved only for kidney transplantation, ongoing studies in thoracic and hepatic grafts may expand its therapeutic role. Personalized patient selection, combination regimens mitigating rejection risk, and real-world cost-effectiveness analyses will define its place in future precision immunosuppression strategies.
