Abstract

A solid organ transplant is life-saving therapy that engenders the use of immunosuppressive medications for the lifetime of the transplanted organ and its recipient. Conventional therapy includes both induction therapy (a biologic that is infused peri-operatively) followed by maintenance therapy. The cost of these medications is a constant concern and the advent of generics has brought this cost down modestly. For those lacking long term insurance coverage, this may be a significant out of pocket expense that is not affordable. Moreover, transplant Centers are managing higher risk transplant recipients that require more complex induction regimens and longer term use of such biologic agents in the context of desensitization or abrogation of de novo antibody mediated injury. While in kidney transplantation, Medicare part B covers three years of medication, there is frequent non-adherence due to cost after that time-point. The impact of the Affordable Care Act remains uncertain at this time. Finally the pipeline of new therapies is limited due to the cost of development of a drug, the inherent cost of clinical studies, and lack of defined endpoints for newer therapies in high risk patients. These new therapies are of high value to the community but will contribute additional burden to current drug costs.

摘要

实体器官移植是一种挽救生命的治疗方法,在移植器官及其接受者的一生中都需要使用免疫抑制药物。传统治疗包括诱导治疗(一种在围手术期输注的生物制剂),随后是维持治疗。这些药物的成本一直令人担忧,仿制药的出现使成本略有下降。对于那些缺乏长期保险覆盖的人来说,这可能是一笔无法承受得起的重大自付费用。此外,移植中心正在管理风险更高的移植受者,这些受者需要更复杂的诱导方案,并在脱敏或消除新发抗体介导损伤的情况下长期使用此类生物制剂。在肾移植中,医疗保险B部分涵盖三年的药物治疗,但在该时间点之后,由于成本原因,患者经常不坚持治疗。《平价医疗法案》的影响目前仍不确定。最后,由于药物开发成本、临床研究的固有成本以及高风险患者中新型疗法缺乏明确的终点,新疗法的研发渠道有限。这些新疗法对社区具有很高的价值,但将给当前的药物成本带来额外负担。
