9080 Phase I oncology clinical trials are critical in the oncology drug development process. To protect human subjects, every phase 1 protocol must be approved by an institutional review board (IRB) to assure safety before patient accrual. As the volume and complexity of phase 1 trials have increased, the amount of time spent on IRB protocol reviews have also increased for various reasons. Objectives: 1) Determine the average time spent on protocol approval by IRB at KCI/WSU; 2) Identify potential issues raised by IRB resulting in approval delays; 3) Identify the redundancies for which “standard language” implementation could facilitate future IRB applications thereby expediting approval. Methods: 96 Phase 1 research IRB applications at KCI/WSU between 8/1/2005 and 10/31/2006 were reviewed. These applications were stratified based on submission (new protocol versus amendment) and IRB approval (tabled, provisional or approved) status. Concerns frequently brought up by the IRB were identified. Results: The average and median time spent from initial submission to final approval of all 96 applications were 41.4 days and 43 days, respectively. Forty eight of 96 applications (50%) were provisionally approved from the initial review. Average and median time of obtaining final approval were 52.5 days and 52 days. Nine of 96 (9.4%) protocols were tabled with their average approval 83 days. The most common concerns raised by IRB were risks/benefit issues. These concerns were an even greater approval barrier when protocols involved specialized technologies of molecular therapeutics or complicated study designs. Regulatory policy changes issued by oversight organizations also required “real-time” updates into protocols and consent form amendments. Areas of “standard language” for future IRB applications are being compiled and will be discussed upon presentation. Conclusion: Phase 1 clinical trials are essential to anti-cancer drug development. The complicated ethical issues and science warrant an ongoing constructive collaboration of both parties. Identification of commonalities that delay IRB approval will lead to more expeditious IRB approval not only at our institution, but could also benefit other institutions.
