IRB approval is usually stressful, but the guidance here made it simple. Documents were flawless, and we avoided the usual delays completely.

Key Takeways

An IIT is a clinical study designed and conducted by a qualified investigator rather than a sponsor, often to explore new indications, mechanisms, or patient populations.

In IITs, the investigator controls study design and conduct, while sponsors may provide support. Sponsor-initiated trials are fully managed by the sponsor.

IITs must follow FDA regulations, ICH-GCP guidelines, and local ethics/IRB approvals. This includes safety reporting and compliance with FDA submission standards.

Investigators are responsible for documenting and reporting adverse events and serious adverse events (SAEs) in accordance with Investigator initiated trials safety reporting standards and FDA guidance.

Services include Investigator-Initiated Clinical Trial Support, regulatory compliance, IND submission, protocol development, medical writing, data management, monitoring, and consulting.

Investigator-Initiated Clinical Trials (IITs) are studies designed and led by qualified investigators rather than sponsors, often exploring new indications, mechanisms, or patient populations.

IITs allow independent exploration of scientific questions, address gaps not prioritized by sponsors, and advance medical knowledge while improving patient care.

ProRelix Research provides comprehensive services for Investigator-Initiated Trials, including clinical trial support, regulatory compliance, FDA IND submission, protocol development, medical writing, data management, trial monitoring, safety reporting, and consulting to ensure efficient and compliant study execution.
