Readministration of abciximab: interim report of the ReoPro readministration registry.
Even with continued improvements in the technology of percutaneous coronary intervention (PCI), approximately 10% to 20% of patients undergoing PCI will require repeat procedures within 1 year. Furthermore, because of the chronic nature of coronary artery disease, many patients will require additional treatment with PCI well after an initial episode of care. Abciximab (ReoPro), a chimeric (murine/human) monoclonal antibody fragment (c7E3 Fab), has been shown to significantly improve periprocedural and long-term outcomes associated with PCI and to reduce the need for repeat target vessel revascularization. However, because the structure of abciximab is derived from an antibody, concern has been raised about subsequent repeat administration. To prospectively evaluate the safety and efficacy of abciximab readministration, we established the ReoPro Readministration Registry with the intent to determine the efficacy, human antichimeric antibody response and rates of thrombocytopenia, bleeding, intracranial hemorrhage, and anaphylaxis in at least 500 patients being retreated with abciximab. The study was conducted at 19 centers beginning in March 1997. This article details interim data that are based on the first 329 patients. Data to date indicate that readministration with abciximab is safe and efficacious and that the same indications for first-time use should apply to subsequent readministration.
