CD4 Update

Omega (AIM: ODX), the medical diagnostics company focused on allergy, food intolerance and infectious disease, announces the following update on its CD4 technology transfer project.

Further to the update given earlier this month, a number of experiments have been performed to investigate the variability within the production process. By definition, the experiments involved testing a number of variant devices, where each individual variant device incorporated controlled changes to a test parameter. The results from testing samples on these variant devices have enabled a majority of variants to be eliminated from further experimentation. The remaining variants are required to undergo further testing in order to select a single preferred manufacturing protocol. This protocol will be subject to a three-batch evaluation and the Board remains hopeful of completing the technology transfer by the end of December 2013 in line with revised expectations. Ultimately, the Board remains very confident of a successful technology transfer and will provide a further update in due course.
