ABSTRACT
An electronic safety reporting (ESR) module was developed and integrated into a home-grown web-based clinical trial management system (CTMS) to enhance the efficiency, completeness and consistency of reporting and reviewing serious adverse events, monitoring safety, and submitting safety reports to regulatory authorities for a large multicenter clinical trial. The architecture of this integrated module provided many advantages. First, the ESR module was developed based on a comprehensive procedure which incorporated both computer logic processing steps and human intervention steps in order to deal with the complex and unexpected situations where pre-programmed computer logic may fail. Second, safety and efficacy data were managed within the same relational database. Relevant data captured on efficacy case report forms, such as demographics, medical history, lab data and concomitant medications, were directly retrievable for MedWatch report composition without requiring redundant data entry. Finally, the ESR module shared the same generic user interfaces and data processing functions with other modules in the CTMS. These generic components include data editing, data retrieving, data reporting, dictionary-based automatic and interactive coding, event-driven and calendar-driven automatic email notifications, and user privilege management. This integrated ESR module was implemented in the Albumin in Acute Stroke (ALIAS) Trial-Part 1. A total of 397 serious adverse event reports were processed and 33 FDA MedWatch reports, 28 initial reports, and 5 follow-up reports were submitted to FDA and Health Canada using this system. Experiences and lessons learned from the development and implementation of this system are presented in this paper.

UNLABELLED: Stroke is a serious global illness. Human albumin has emerged as a putative therapy for ischaemic stroke based on strong evidence from animal models. Following confirmation of the safety and feasibility of high-dose albumin treatment for acute ischaemic stroke in a pilot study, the Albumin in Acute Stroke trial, a phase 3 randomised, double-blinded, placebo-controlled clinical trial was initiated to evaluate the efficacy of high-dose albumin compared to saline control within 5 h of ischaemic stroke onset. METHODS: The trial will enrol 1800 patients in two cohorts--a thrombolytic and a nonthrombolytic arm. High-dose (2 g/kg) human albumin will be administered in a 2-h straight intravenous infusion to ischaemic stroke patients, within 5 h of symptom onset. The primary outcome will be an NIH stroke scale score of 0-1 or a modified Rankin scale score of 0-1 at 90 days. Safety outcomes will include the incidence of congestive heart failure after study-drug administration. RESULTS: Enrolment opened at 40 sites in August 2006; new sites continue to be added. Recruitment is ongoing and is projected to be completed by 2010. CONCLUSIONS: The trial will continue through 2010. The study is proceeding as planned.
