Clinical, Research Associate 

There was a patient participating in an ulcerative colitis study who was scheduled to come in at one of my sites, but the medication had been quarantined and the new drug wasn't scheduled to arrive until the day after the patient was due to be dosed. The patient and study coordinator were able to work together quickly to reschedule and avoid late dosing and potential risk of flares. It was amazing to witness the commitment and caring of everyone involved to keep the patient's well being at the core of our activities.



Senior Project Leader

I was a Project Leader on a Respiratory Syncytial Virus (RSV) pediatric study. At that time my son was about 2 years old, and our patients were up to 2-year-old children which are under a huge risk of severe, life-threatening RSV infections. This was a potential new therapy for RSV giving little patients better chances to survive the infection in the infant age. I remember asking myself a question, ‘Would I agree for my son to participate in such a study?’ and my answer was yes. This gave me additional strength, motivation and energy to put all my heart into this study.

Project Specialists and sisters

The patients are our main motivation for working With Heart™. In 2006, our eldest sister was diagnosed with Systemic Lupus Erythematosus (SLE) and sadly passed away in 2008. Back then, we didn’t know a lot about clinical trials but working at Parexel has broadened our knowledge of how much clinical trials are needed to improve the lives of so many people suffering from various illnesses including SLE. We are grateful that Parexel oversees clinical trials for SLE. Knowing that there are people who will receive some form of treatment for this dreadful illness is a definite personal motivation for us to make sure that we always adhere to the core values of Parexel: Patients First, Quality, Respect, Empowerment and Accountability.
