Phase II - IV Outpatient Trials


Riverstar Research specializes in Phase II-IV multi-specialty trials, with an emphasis on CNS.  

Our diverse executive team has over 35 years of combined industry experience.  We have been involved in over 200+ Phase II-IV trials and were consistently among the highest enrollers in these trials.  In addition to our strong enrollment, we have an exemplary audit record, having been a part of several successful audits.  This experience has earned us a reputation within the clinical trials industry for building and managing first-rate research sites and has been instrumental in building long lasting relationships with Sponsors and CROs.

Riverstar Research runs on management systems that allow for efficient workflow and the effective management of all our Phase II-IV trials.  These systems allow us to provide expedited study setup and training, fast regulatory document turnaround and ensure timely subject recruitment and data capture.  We are able to move fast, while providing excellent results, making us an ideal choice not only for studies in the startup phase, but for those requiring add-on or rescue sites.

It is this experience, along with our well-trained, experienced staff and proven trial management systems, that make Riverstar Research a leading Phase II-IV site.
