Liquent provided an integrated platform of software solutions for regulatory submissions and product registration management, as well as a range of complementary business process outsourcing capabilities.[6]

In 2008, PAREXEL closed the acquisition of ClinPhone plc, combining the company with its wholly owned subsidiary Perceptive Informatics, to provide additional eClinical solutions to facilitate the clinical development process. The Perceptive Informatics expanded technology portfolio now includes Randomization and Trial Supply Management technologies, Electronic Data Capture, Medical Imaging, Clinical Trial Management Systems (CTMS), and Electronic Patient-Reported Outcomes (ePRO). Perceptive Informatics won the European Outsourcing Award in 2009 for the Best e-Business/IT Strategy from PharmaTimes.

During 2007, PAREXEL completed the acquisition of Taiwan-based APEX International Clinical Research Co., Ltd. APEX locations were combined with the company’s previous existing presence in Japan, India, and Australia to expand its clinical research services throughout the Asia/Pacific region, including in mainland China, Hong Kong, India, Taiwan, Singapore, Indonesia, South Korea, Malaysia, Thailand, the Philippines, New Zealand and Australia. PAREXEL has 1,600 employees in the Asia/Pacific region and 17 offices throughout 12 countries. Prior to the acquisition, in 2003 PAREXEL had purchased a minority interest in APEX, which had carried out numerous clinical studies with PAREXEL. PAREXEL received the BioSingapore Award for Best Performing CRO in 2009 from BioSingapore, an industry association for life sciences businesses encouraged by the Economic Development Board of Singapore.

In 2006, PAREXEL completed the acquisition of California Clinical Trials Medical Group, Inc. (CCT) and Behavior Medical Research LLC, which provided the company with a broad range of specialty Phase I-IV clinical research services through sites in California. The acquisition expanded PAREXEL’s early phase bed capacity, now currently 580 beds globally, and brought new service offerings in the area of bridging studies, as well as expertise in neuroscience drug development, central nervous system, and sleep studies.


TeGenero Clinical Trial[edit]

Main article: TGN1412

In March 2006, a PAREXEL-run trial on behalf of TeGenero, the now bankrupt German biotechnology firm, on its anti-inflammatory drug TGN1412 to treat rheumatoid arthritis, multiple sclerosis or leukaemia, unexpectedly caused severe inflammation and multiple organ failure in six healthy volunteers at a facility based at Northwick Park Hospital in London.[7] The drug had been tested on animals but this was the first test on humans.

PAREXEL became the target of legal proceedings from lawyers representing the injured volunteers after the insurance policy of TeGenero was unable to provide sufficient compensation. When the liable company[8] subsequently declared bankruptcy,[9] lawyers for the volunteers initiated legal proceeding against PAREXEL and the two parties later entered into talks;[10] the results of this meeting have not been made public.[11][12]

A documentary shown in the UK on 28 September 2006 featuring journalist Brian Deer as part of Channel 4's Dispatches series exposed uncertainty about the existence of data that should mandatorily have been submitted by TeGenero to the Medicines and Healthcare products Regulatory Agency (MHRA) prior to the trial indicating whether TGN1412 had been adequately tested on human blood in vitro. Concerns were also raised about whether a safe human dosage was properly obtained by TeGenero. The MHRA however concluded that none of the companies involved could be held responsible for the outcome of the test and that the adverse events that occurred were most likely caused by an unpredicted biological action of the drug in humans.[13]
