AspenBio Outlines Steps for FDA 510(k) Clearance of AppyScore(TM), the First Blood-Based Screen/Triage Test for Human Appendicitis

Clinical Data Collection Continues to Support High Test Sensitivity

    CASTLE ROCK, Colo., Dec. 27 /PRNewswire-FirstCall/ -- AspenBio Pharma,
 Inc. (Nasdaq:   APPY), an emerging bio-pharmaceutical company dedicated to
 the development of novel drugs and diagnostics for animals and humans, has
 outlined plans for submitting its final data package to the United States
 Food and Drug Administration ("FDA") for market approval of AppyScore(TM),
 the first blood-based screen/triage test for human appendicitis.
     Following its official pre-IDE response from FDA in November, AspenBio
 plans to complete the final data package for a 510(k) submission by mid to
 late 2008. FDA regulations require the FDA to complete the 510(k) review
 within 90 days of submission. Steps currently proceeding under supervision
 of the company's FDA consultants cover the following primary areas:
1) Pivotal clinical data trial definition and completion under FDA regulatory guidelines using GMP validated test version 2) Finalization of logistics with cGMP manufacturer of the AppyScore test 3) Preparation of FDA 510(k) final data submission package for clearance by FDA In order to receive FDA 510(k) clearance, AspenBio must successfully demonstrate the performance characteristics of its final GMP-validated device. This includes non-clinical laboratory performance testing, like assay precision and analytical sensitivity, as well as clinical testing in the field. AspenBio has selected a manufacturer for the AppyScore Screen Test with extensive experience in manufacturing in-vitro diagnostic devices according to 21 CFR 820, and which has been registered with the FDA to manufacture these types of devices. As disclosed in a September 28, 2007 press release, AspenBio's pre-FDA multi-hospital study substantially advanced the optimization of sampling and testing methodologies necessary for FDA clinical studies. AspenBio and its FDA advisors are finalizing the clinical protocol that will involve testing of about 500 patients in multiple hospital sites. Based upon AspenBio's prior experience with patient recruitment rates in the pre-FDA preliminary studies, the company expects this final FDA clinical study to be completed within five to six months. The clinical portion of the 510(k) application will be conducted concurrently in accordance with FDA guidelines and as directed by the company's FDA consultants. AppyScore Screen Test is designed to screen patients suspected of having appendicitis. Emergency room physicians are expected to use the device as part of a complete clinical workup. The key metric for the clinical study is the device's Negative Predictive Value, which has been shown consistently in pre-FDA clinical studies to be approximately 98%. "Our path to FDA 510(k) clearance is clear and well planned, and we are excited to be moving so rapidly toward the commercialization of this first-generation blood test for appendicitis," said AspenBio Pharma president and CEO, Richard Donnelly. "Ongoing data collection continues to support the exceptional effectiveness and efficacy of AppyScore, and we are carefully taking the final steps necessary to deliver a high-quality, first-of-its-kind appendicitis screen blood test to the U.S. market. Appendicitis is expected to afflict five to seven percent of the world's population at some point in their lives, so the worldwide market potential for this test is tremendously vast. Given our achievements over the last year that have taken us far down this path for final data acquisition and submission, we have every reason to expect FDA 510(k) clearance for AppyScore before the end of 2008."
