Trial master file

Trial master file is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Trial master file rather than just read about it. In short: In order to comply with government regulatory requirements pertinent to clinical trials, every organization involved in clinical trials must maintain and store certain documents, images and content related to the clinical trial. Depending on the regulatory jurisdiction, this information may be stored in the Trial Master File or TMF, which today takes the form of an electronic trial master file (eTMF).

Key takeaways

  • Trial master file belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Trial master file to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Trial master file from memory before moving on to harder problems.

Reference excerpt

In order to comply with government regulatory requirements pertinent to clinical trials, every organization involved in clinical trials must maintain and store certain documents, images and content related to the clinical trial. Depending on the regulatory jurisdiction, this information may be stored in the Trial Master File or TMF, which today takes the form of an electronic trial master file (eTMF). The International Conference on Harmonization (ICH) published a consolidated guidance for industry on Good Clinical Practice in 1996 with the objective of providing a unified standard for the European Union, Japan, and the United States of America to facilitate mutual acceptance of clinical data by the regulatory authorities in those jurisdictions. This guidance document established the requirement across all ICH regions to establish trial master files containing essential documents that individually and collectively permit evaluation of the conduct of a trial and the quality of the data produced.[2] In some jurisdictions, for example the USA, there is no specific requirement for a trial master file. However, if the regulatory authority requires ICH GCP to be followed, then there is consequently a requirement to create and maintain a trial master file.[2]

History In a clinical trial involving human subjects, a set of content known as a trial master file (TMF) must be produced in accordance with applicable international and local regulations. TMFs are a collection of documents and other artifacts which "individually and collectively permit evaluation of the conduct of a trial and the quality of the data produced. These documents serve to demonstrate the compliance of the investigator, sponsor and monitor with the standards of Good Clinical Practice and with all applicable regulatory requirements." Historically, TMFs have been paper-based content sets stored in physical file cabinets, central file rooms, or shelved in binders. The size and complexity of a TMF is in direct proportion to the length and complexity of the trial. The TMF is actively built during a trial, and must be maintained during a post-trial period for possible regulatory agency inspection in alignment with GCP and local country regulations. Traditionally, the TMF content names and requirements varies from sponsor to sponsor, creating a high degree of variability and inconsistency.

TMF definition A trial master file contains essential documents for a clinical trial that may be subject to regulatory agency oversight. In the European Union (EU), TMFs have a different definition and set of requirements than in the US. The EU Commission's Directive 2005/28/EC 63 Chapter 4 states 'the trial master file shall consist of essential documents, which enable both the conduct of a clinical trial and the quality of the data produced to be evaluated. Those documents shall show whether the investigator and the sponsor have complied with the principles and guidelines of good clinical practice and with the applicable requirements.' The US FDA recognizes the use of TMFs as a significant piece of information but unlike the EU with its TMF regulation, there is no formal requirement for maintenance of essential documents in a TMF in US-based clinical trials in the U.S. Code of Federal Regulations. However, since the U.S. FDA require trials to be conducted in compliance with ICH GCP, there is an expectation that a trial master file will be created and maintained in accordance with those guidelines.

TMF content The United States, the EU and Japan support the International Conference on Harmonisation or ICH. The ICH has published a minimum set of essential documents for the TMF. The minimum essential documents that are required for the registration of pharmaceutical products designed for human use are specified in the document 'ICH Good Clinical Practices,' published in 1997 by the ICH Example ICH essential documents that would be required in any US, EU or Japan based clinical trial would include: signed protocol, audit certificate, subject enrollment log. Although the ICH guidelines are applicable to the three named ICH regions, many other countries have agreed to follow the guidelines and have incorporated the principles into their national medicines legislation. Creation of a TMF and inclusion of ICH essential documents is based on the discretion of the regulatory agency for the country in which the clinical trial is conducted. In addition, the submission of a marketing application will normally require compliance with the regulatory requirements of that country, including requirements specific to TMF content.

Worked examples

Example 1 — a first encounter with Trial master file

Start with the simplest possible case. Write down what Trial master file claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Trial master file before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Trial master file ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Trial master file

In research
Trial master file appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Trial master file in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Trial master file is common in secondary-school and first-year university syllabi. It links to neighbouring topics Clinical trials, so understanding it makes those chapters shorter.
In everyday life
Look for Trial master file outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
