Perceptive Informatics and Acurian Announce Strategic Product Development Partnership

Perceptive Informatics, Inc., a subsidiary of PAREXEL International Corporation (Nasdaq: PRXL), and provider of innovative technology-based solutions designed to accelerate drug development, and Acurian, Inc., a leading provider of direct-to-patient recruitment, investigator recruitment, and centralized patient screening technology, announced that the two companies have expanded their strategic product development partnership. Perceptive Informatics will integrate Acurian’s investigator database and aggregate patient data into IMPACT, its leading clinical trials management system (CTMS), and into INVESTIGATOR, its proprietary investigator database solution. Bio/pharmaceutical companies and clinical research organizations (CROs) will have online accessibility to evaluate investigator sites, based on performance as well as proximity to relevant populations of potential study participants. Sponsors will be able to utilize the technology to leverage investigator and patient data, and gain competitive and cost advantages.

Investigator selection is critical to the success of clinical development studies. According to Acurian project data, the top quartile of investigative sites consistently outperforms the bottom quartile by a factor of four to six times. Acurian’s investigator database currently contains searchable profiles of over 48,000 US-based investigators, enabling sponsors to rapidly and objectively evaluate research physicians for clinical trials.

With over 14,000 users worldwide, Perceptive’s IMPACT enables bio/pharmaceutical companies and CROs to better administer the complex process of conducting clinical trials. INVESTIGATOR is a flexible, web-based clinical investigator system that combines a rich data repository with a decision support environment, enabling companies to leverage investigator data across the entire enterprise.

“We are very pleased to be working with Perceptive Informatics, and to extend our integration with both IMPACT and INVESTIGATOR,” said Mark Eisenach, Acurian’s CEO. “Together we will offer customers the ability to make better decisions regarding who they select to run their trials, which can ultimately reduce clinical trial costs and accelerate enrollment.”

“Our relationship with Acurian is yet another indication of our commitment to providing customers with robust and functionally rich clinical trials management solutions,” added Mark A. Goldberg, MD, President of Perceptive Informatics, Inc. “By combining our online accessibility to critical trial management data with Acurian’s investigator and patient recruitment solutions, we believe we can add real value to the clinical development process.”
