Study Design and Protocol Writing

The Principal Investigators affiliated with Julius Clinical Research have a widely published track record in the design of phase II-IV clinical trials. Intelligent and sophisticated study design based on thorough analysis of the drug and the main hypothesis under research, is one of the most important and unique strengths of Julius Clinical Research. This has frequently resulted in a reduction of timelines and costs in the development programs of new drugs.

 

Underneath, please find some examples of phase II-IV clinical trials that have been designed and conducted by Julius Center/ Julius Clinical Research.
