A CTMS is software for running the operations of a clinical trial: which sites are active, what milestones are due, which monitoring visits are done, and what is owed to whom. It tracks the trial itself, not the participant data.

In short
Explained
Every trial has two streams of information. One is clinical: what happened to each participant. The other is operational: which sites have been selected, which have approvals, who has been trained, how many people have been screened against target, whether a monitoring visit is overdue, which invoice has been paid. The first stream lives in the EDC. The second stream is what a CTMS exists to hold.
Typical CTMS functions fall into a handful of groups. Study and site set-up records, with contacts, addresses and status. Milestone tracking, from first site selected to last participant out. Monitoring visit planning and reports, including follow-up items. Enrolment tracking against targets. Contract, budget and payment tracking for sites and vendors. Document tracking links, and reports for sponsors and oversight committees. The exact feature set differs by product, so check what a vendor includes before assuming it.
The simplest test is the question being asked. "Has site 04 completed its monitoring visit?" is a CTMS question. "What was participant 04-007's systolic pressure at week 4?" is an EDC question. Because they hold different records, the two systems are usually connected by exports or integrations, such as enrolment numbers passed from EDC to CTMS. Our longer comparison, EDC versus CTMS, covers the overlap in detail.
The eTMF is the filing system for essential documents such as approvals, delegation logs and training records, which inspectors review. The CTMS tracks operational status. A CTMS may record that an ethics approval is expected on a date; the approval letter itself belongs in the TMF. See EDC versus eTMF for how the document file relates to the data system.
Operational data is usually owned by the sponsor or the contract research organisation (CRO) running the study, while clinical data collected in the EDC belongs to the study and is locked at the end through database lock. Keeping the roles and permissions in each system matched to people's actual jobs is a recurring audit theme.

Products vary. Some vendors bundle these functions; check the feature list rather than the label.
Capture is where the participant data is built, collected and audited. Build your study and test it in the sandbox before any operational tooling decisions.
In Capture
Capture is a self-serve platform for the data side of a trial: EDC, eCRF builder, ePRO, eConsent, randomization, safety reporting and monitoring workflows, in one system with one audit trail. Multi-site features include site-specific QR enrolment, site-level participant numbering, a site coordinator portal and by-site filtering and exports, which gives study teams a per-site view of enrolment and data without a separate tool.
Decision aid
One to three sites can often be tracked on a shared spreadsheet. Ten or more sites with milestones and payments tends to justify dedicated tooling.
If a CRO runs monitoring, it will usually bring its own CTMS. Ask which system they use and what reports you receive.
Payment tracking against completed visits is one of the first things teams outgrow spreadsheets on.
Some require periodic enrolment and milestone reporting; confirm the format early.
Enrolment by site, query backlog and visit completion often come straight from the EDC and cover the basics.
Clinical trial management system. It is software for managing the operational side of a clinical trial.
A CTMS tracks operations such as sites, milestones, monitoring visits and payments. An EDC collects and audits the clinical data about participants. They answer different questions and are often connected but separate.
No. The eTMF stores the essential documents of the trial for inspection. The CTMS tracks operational status. Some vendors sell both together.
No regulation requires a CTMS by name. Sponsors must oversee the trial and keep essential documents and records; how they do so is their choice, and many use spreadsheets for small studies.
Often not at first. A single-site or few-site study can usually track milestones and visits in a spreadsheet next to the EDC. The need grows with the number of sites, vendors and payments.
No. An EDC covers participant data and data quality. Some EDC systems report enrolment and queries by site, which covers part of the operational picture, but contracts, budgets and payments are separate.
