Orbofiban was developed as an orally active glycoprotein IIb/IIIa antagonist. By 2001, this drug had progressed to phase III clinical trials. Unfortunately, was found that orbofiban induced thrombocytopenia and thrombosis. In addition, despite no significant excess risk of intracranial hemorrhage, orbofiban was not effective in preventing ischemic stroke or transient ischemic attack. Besides, the use of this drug had led to an increase in mortality. Based on all these results further development of this drug was discontinued.
