PTI Pulls Filing

Precision Therapeutics Inc., a Pittsburgh-based oncology services company, has withdrawn registration for its IPO. The move comes just days after the company agreed to go public via a reverse merger with special purpose acquisition company Oracle Healthcare Acquisition Corp. (OTC BB: OHAQ). PTI has raised around $84 million in VC funding since 1996, from firms like Adams Capital Management (39.1% stake), Quaker BioVentures (21.5%), TVM Capital (9.1%), Birchmere Ventures (8.8%), Stephens Group (6.5%) and Draper Triangle Ventures.
