Wyzwania to Wdrażanie

Despite the road to adopting biologics for Addisn 's disease is fraught wigh obstacles. First, the precise imty target (s) driving adrenang ar autoimmunoty are not fuly elucidated. While TNF- α ande IL- 17 are implicated, it unclear which pathway is dominant in humans. Thee rarity of thee disease also complicates trial recuritment; conventional parallel- group trials may bee impraktycal with out international attion.

Second, safety concerns are e paramount. Biologics carry inherent risks of serious infections, infusion reactions, ande in some cases increase and candisee cases increase cancer. Thee potential for biologics to induce neutrilizing anti- drug antibodies adds anotherr layer of complecity, especially if treatments needs to be incordict and restard.

Third, timing of intervention is critical. By the time a patient is diagnosed, substantial adrenal tissue has already been lost. Biologics are most likely to be effective in the preclinical or early subclinical phase, which requires better screening biomarkers and risk stratification. The development of validated surrogate endpoints—such as changes in autoantibody titers, T-cell activation markers, or adrenal volume measured by MRI—is essential for designing feasible trials. However, regulatory agencies have not yet accepted these surrogates for approval.

Cost is anothert barrier. Biologic therapies are locsive, and health systems may be instiltant to fund them for a condition in which quantiquatique; safe and effective convettivy quantity quality of life.
