Frequently asked questionsWhat is the Pan African Clinical Trials Registry?
The South African Cochrane Centre (SACC), in partnership with The European and Developing Countries Clinical Trials Partnership (EDCTP) and the Cochrane Infectious Disease Group,
has established an international registry for all clinical trials conducted in Africa.
The Pan African Clinical Trials Registry (PACTR) is an African initiative to support regional
clinical trial registration. The PACTR is an official registry and member of the World Health Organization (WHO) Network of Primary Registers.The PACTR provides data to the central
WHO International Clinical Trials Registry Platform (ICTRP), so that trials registered in the PACTR are represented in global searches

What are the aims of the Pan African Clinical Trials Registry?
The Registry aims to:
The Pan African Clinical Trials Registry aims to increase the number of trials in Africa that are
registered prospectively. In the initial phase, the registry registered trials in HIV/AIDS, Tuberculosis and Malaria to demonstrate proof of concept. Once established, the goal is that
the Registry will become the register of choice for any clinical trial conducted in Africa. The Registry is presently the only Africa member of the WHO Network of Primary Registers and
transfers all trial information to the WHO International Clinical Trials Search Portal on a quarterly basis.
- Provide a repository for prospective registration of clinical trials conducted in Africa
- Promote prospective clinical trial registration in the African region
- Ensure the WHO-stipulated minimum dataset for registered trials is publicly and freely available to all users of the registry
- Provide a searchable database of all clinical trials conducted in Africa.
What does it mean to be a member of the WHO Network of Primary Registers (NPR)?
Primary registry status is granted by the WHO only to registries who meet specific criteria for content. Criteria are separated into six categories, namely, content, quality and validity,
accessibility, unique identification, technical capacity and administration, and all categories must be met in order to receive primary registry status.
WHO primary registries meet the requirements of the ICMJE which stipulate that in order to be published in a member-journal, registration is mandatory.
How will the information contained in
the registry be useful?
The Pan African Clinical Trials Registry will be an important global resource for researchers, clinicians, policy makers and the lay public by:
The Pan African Clinical Trials Registry is unique in recognising that African trialists face additional challenges in trial registration and seeks to provide feasible ways of overcoming these.
Due to the limited and unreliable access to the internet experienced by individuals in a number of African countries, trials may be registered online,
(via the internet if access is sufficiently reliable) or by email, postal mail or facsimile.
- Providing a source of reliable information on the efficacy and safety of prevention and treatment measures
- Identifying research gaps that should be addressed in future trials
- Providing a "laboratory" for studying the scope, quality and funding patterns of trials
- Keeping track of on-going trials
- Ensuring effective allocation and use of limited research funding
- Decreasing wasteful duplication of research
- Promoting research collaboration within the region
- Providing a potential means of regulating clinical trial activity in Africa.
What is a clinical trial?
There are many definitions of clinical trials. In general clinical trials are biomedical or
health-related research studies in human beings that follow a pre-defined protocol. A clinical trial is prospective research designed to evaluate the safety and/or effectiveness of drugs,
medical devices, treatments or preventive measures in humans. For more information see World Health Organization International Clinical Trials
Registry Platform (WHO ICTRP) or the Ottawa Statement
Since clinical trials have been variably defined, it is important for PACTR to clearly state what we include in our definition.
How does the PACTR define clinical trials?
PACTR accepts interventional RCTs and CCTs, pharmacokinetic and pharmacodynamic studies on its registry (including phase 1 - 4 trials).
A Randomized Control Trial (RCT) is a trial in which participants are randomly allocated to one of two or more intervention arms allocating
people to groups using a method based on chance (e.g., random number table, random computer-generated sequence, minimization, adaptive randomization).
The control group is usually given either the standard intervention for the disease in question or a placebo while the other group (or groups) is assigned
to the experimental arm(s) (drug or other intervention).
A Controlled Clinical Trials (CCT) is a trial in which participants are allocated to one of two or more intervention arms allocating people to groups
using a method not based on chance (e.g., birthdate, day of the week registered, etc.). The control group is usually given either the standard intervention for
the disease in question or a placebo while the other group (or groups) is assigned to the experimental arm(s) (drug or other intervention).
What does the PACTR exclude from its definition of clinical trial?
Observational studies which are studies in which individuals are observed and their outcomes are measured by the investigators.
Why is it important to register your clinical trial?
There are both ethical and scientific reasons for registering trials. People who participate in clinical trials expect their contributions to be made use of in improving health care for everyone.
Open access to information about ongoing and completed trials will satisfy the ethical duty to trial participants and will promote greater trust and public confidence in clinical research.
Clinical trial registration in open access registries will also reduce selective publication of trial results.
In addition to this clinical trial registration will decrease wasteful duplication of research, promote international research collaboration and ensure more efficient and effective allocation of research funds.
What is a clinical trial register?
A clinical trial register is essentially a database that contains pertinent information (both administrative and scientific information) on each registered trial.
Which trials may be registered with the Pan African Clinical Trials Registry?
All clinical trials conducted in Africa may be registered in the Pan African Clinical Trials Registry. We encourage the registration of early phase trials and pilot studies.
What do I need to know before I register my trial?
- You must register as a user on the Pan African Clinical Trials Registry
- The trial you want to register must be an interventional clinical trial.
- Trial registrants must be provide copies of ethics approval
- You must have all the information to be able to complete the WHO dataset . All PACTR fields must be completed before a PACTR trial number is assigned.
- You must be registering the trial before enrolment of the first participant to meet the publication pre-requisites of the International Committee of Medical Journal Editors (ICJME) to publish in any of their member-journals
If the trial is already registered with a Primary or Partner register within the WHO ICTRP Registry Network, must the trial be registered again with the Pan African Clinical Trials Registry?
If your trial is already registered with a WHO Primary Register, there is no need to register the trial again with the Pan African Clinical Trials Registry.
If you have registered your trial in a registry that is not acknowledged within the WHO ICTRP Registry Network, it would be advisable to register with one of these in order to ensure that you fulfill journal requirements.
Who should register the trial?
It is recommended that the trial sponsor register the trial.
However trial coordinators or principal investigators may also register the trial.
For multi-site studies trial data should be submitted only once. (Do not submit trial data for each study location).
The trial registrant is responsible for:
- the accuracy and completeness of registered data
- ensuring that information on any one trial is submitted only once
- communicating with trial collaborators regarding the registration status of the trial, and the registration number
- ensuring information on the registered trial is kept up-to-date
When should a trial be registered?
Ideally, trials should be registered before the enrolment of the first participant. Trials may be registered either before or after receiving regulatory and/or ethics approval.
