11. ROLE AND RESPONSIBILITIES OF CLINICAL TRIAL PERSONNEL AS PER ICH GCP

The conduct of a clinical trial requires the coordinated effort of multiple trained professionals. The International Council for Harmonisation – Good Clinical Practice (ICH GCP) guidelines outline clear responsibilities for each member involved in clinical research. These guidelines ensure scientific integrity, ethical conduct, participant safety, and high-quality data. This article provides an organized and easy-to-understand overview of the roles of clinical trial personnel including the Sponsor, Investigator, CRA, CRC, Auditor, and Regulatory Authorities.

1. Sponsor

The sponsor is an individual, company, or institution that initiates, manages, and finances a clinical trial. As per ICH-GCP, the sponsor’s responsibilities include:

  • Selection of Qualified Investigators: Sponsors must choose trained and experienced investigators and ensure that trial sites have the necessary facilities. :contentReference[oaicite:0]{index=0}

  • Maintaining communication between investigators and the sponsor. :contentReference[oaicite:28]{index=28}
  • Performing quality assurance and ensuring correct documentation. :contentReference[oaicite:29]{index=29}

4. Clinical Research Coordinator (CRC)

The CRC works under the PI and manages day-to-day trial activities at the site.

Before Trial Initiation

  • Completing feasibility forms and budget preparation. :contentReference[oaicite:30]{index=30}
  • Preparing and submitting IRB/IEC documents including protocol, IB, and ICF translations. :contentReference[oaicite:31]{index=31}
