Parallax Clinical Research was founded by a group of experienced scientists and clinicians dedicated to the facilitation of translational research.  Translational research is defined as: “The process of translating discoveries in the laboratory into clinical interventions for the diagnosis, treatment, prognosis, or prevention of disease with a direct benefit to human health.”  Parallax has established a network of scientific, clinical and operational experts who are committed to leveraging their cumulative pharmaceutical knowledge to facilitate the development of novel therapeutics. Parallax has worked with over 20 pharmaceutical and biotechnology companies, facilitating their entry into clinical trials. 

Beginning with the process of discovery, through animal toxicology, pharmacology, and increasingly complex phase 1, 2, and 3 studies designed to satisfy the most demanding regulatory reviewers, the modern drug discovery process is complex and requires the application of extensive resources.

To successfully gather the essentials of a successful NDA application requires the input of a wide range of skills and expertise. At Parallax Clinical Research, we have put together an outstanding group of skilled professionals with many years of experience in the pharma industry to assist in the process. We pride ourselves on our scientific and operational expertise that would make us an asset to assist with all aspects of the clinical development process from development strategy to submission.
