Investigator-Initiated Trials (IITs)

Investigator-Initiated Trials (IITs) are clinical trials in which the investigator assumes the roles of both the sponsor and the investigator.

Empowering Independent Research with Professional CRO Support

Investigator-Initiated Trials (IITs) are clinical studies where the investigator assumes both the sponsor and investigator roles. In these trials, the investigator is responsible for developing the protocol, initiating the study, and administering the investigational product—while also overseeing the trial’s conduct and data collection.

Although the investigator leads the study, the distinct responsibilities of sponsor and investigator still apply, requiring both scientific expertise and operational oversight.

Clinixir supports the success of IITs through expert clinical data management, statistical analysis, and regulatory guidance—ensuring research is not only scientifically sound, but also compliant and publication-ready.

Key Considerations for a Successful IIT Application

The process of initiating an IIT typically begins with a concept note submitted to a sponsor, followed by a full proposal. These proposals are carefully reviewed and evaluated against several key criteria:

Why IITs Matter

IITs play a vital role in advancing medical knowledge through independent research. These studies generate non-industry-sponsored data, which can enhance the credibility of findings and provide new insights that support product development or market expansion.

By improving clinical outcomes and contributing to scientific literature, IITs help drive innovation across the healthcare ecosystem.
