How to hire a Clinical Trial Assistant (CTA)

What a CTA does, how the role differs from a CRA and what to assess when adding a CTA to your Clinical Operations team in Latin America.

The CTA provides operational and documentation support to the study team, keeping files, systems and timelines in order.

What a CTA does

  • · Maintains and quality-checks the Trial Master File (TMF/eTMF).
  • · Tracks essential documents, site contracts and payments, depending on the organisation.
  • · Updates the CTMS and prepares status reports.
  • · Coordinates meetings and shipments of study materials.
  • · Supports CRAs and the Clinical Trial Manager.

CTA vs. CRA

The CTA works mainly in-house, with documents and systems; the CRA visits and monitors sites. The CTA role is often a step towards becoming a CRA, which is worth considering for retention and career planning.

Define the profile

  • · Background in life or health sciences.
  • · Experience with documentation or at a clinical research site (preferred).
  • · Comfort with eTMF, CTMS and office tools.
  • · English for documentation and meetings with global teams.

What to assess

  • · Attention to detail: how they check a document before filing it.
  • · Organisation and follow-up of open items.
  • · Understanding of what the TMF is and why it matters for inspection readiness.

ECR Talent supports CTA searches for CROs, sponsors and clinical research sites across Latin America.
