Continued access can be defined as the continued provision of the investigational medicine or continued maintenance of the investigational significant risk device for any clinical trial participant after participation in the trial. Some investigational interventions may require unique supportive care that should be considered by the sponsor, researcher, healthcare systems, or host country governments. Post-trial, continued access is a shared responsibility and should be determined before the trial begins.
The PTR task force developed a revised set of principles with associated analysis and a framework of responsibilities for continued access to investigational medicines and a framework for significant risk (SR) devices after a clinical trial: scenarios that require further consideration.
Research participants deserve consideration of continued access to an investigational product to which they have received benefits as part of a clinical trial.
International ethical guidelines, including the Declaration of Helsinki and the Council for International Organizations of Medical Sciences (CIOMS) discuss the responsibilities stakeholders have to provide continued access to investigational products. Notably, in 2024, paragraph 34 of the Declaration of Helsinki was revised to reflect the responsibilities that sponsors and researchers have to plan for post-trial provisions and the role research ethics committees play in approving exceptions.
Post-Trial Provisions
34. In advance of a clinical trial, post-trial provisions must be arranged by sponsors and researchers to be provided by themselves, healthcare systems, or governments for all participants who still need an intervention identified as beneficial and reasonably safe in the trial. Exceptions to this requirement must be approved by a research ethics committee. Specific information about post-trial provisions must be disclosed to participants as part of informed consent.
World Medical Association. (2024). WMA Declaration of Helsinki: Ethical principles for medical research involving human subjects
There is no guidance or instruction on fulfilling the responsibilities set forth in the Declaration of Helsinki and CIOMS. To fill this gap, the MRCT Center convened a group of experts to develop and put forth actionable and practical tools to help sponsors and researchers understand their ethical responsibilities and how to achieve them practically. We have developed a series of resources, including principles, frameworks, recommendations, and case studies.
The MRCT Center’s Post-Trial Responsibilities: Continued Access to an Investigational Product outlines a principled and practical approach to identify the shared ethical responsibilities that can, in turn, guide action to provide continued access to an investigational product at the conclusion of a patient’s participation in a clinical trial.
The foundation of the MRCT Center’s work is grounded in 12 principles. The principles, accompanied by an analysis, should be read as a whole.

This image illustrates the shared responsibility of continued access throughout product development in an ideal situation, from planning to marketing to product availability. The work of the task force focused on challenging scenarios when this ideal situation does not happen.
The sponsor should apply interdependent criteria to determine whether continued access will be offered tostudy participants.
The MRCT Center has defined a set of interdependent criteria related to the study program that may lead to continued access, which may include but are not limited to:
In addition, the following criteria should be considered at completion of the trial:
Sponsors and Researchers generally agree upon the criteria used to determine post-trial, continued access, the regulatory milestones, and the mechanisms used to provide continued access. The timing between a pivotal trial of an investigational product and its regulatory approval is variable, as is the timing to commercial milestones such as market availability and reimbursement. It is in these windows that decisions about the provision of continued access must be made. There are, however, complex decisions that require further analysis.
The Framework of Responsibility: Scenarios that Require Further Consideration is a list of considerations that organizations can utilize to make equitable and fair decisions related to continued access to an investigational medicine or significant-risk (SR) device. These frameworks were designed for organizations developing investigational products and can be utilized to develop policy or guidance.
In November 2017, the MRCT Center published the Post-Trial Responsibilities: Continued Access to Investigational Medicines Guidance Document and Toolkit. This original framework outlined a case-based, principled, stakeholder approach to evaluate and guide the ethical responsibilities related to providing continued access to investigational medicine at the conclusion of a patient’s participation in a clinical trial. These resources have been used to develop policies and procedures at many global research organizations.
In 2022, the MRCT Center initiated the “PTR Taskforce” to update and add to the original resources. Utilization identified that the ethical principles and main consensus points remained valid. However, additional work was needed to advise on the practical application of the work. Throughout 2023 and the early months of 2024, the MRCT Center met monthly with the PTR task force to identify and develop updated tools and resources. The PTR task force developed a revised set of principles with associated analysis and a framework of responsibilities for continued access to investigational medicines. At the beginning of 2024, the work pivoted to the challenges of continued maintenance of investigational significant-risk (SR) devices after a clinical trial. The MRCT Center, working with device experts, developed a device-specific framework of responsibilities reflecting the unique challenges of post-trial continued access to and maintenance of SR devices. This work was released in April 2025.
ONGOING & FUTURE WORK
In 2025 and 2026, the MRCT Center will focus on the challenges of continued access in lower- and middle-income countries. This work started in November of 2024 during a hybrid meeting of involved parties. Additional future work will focus on post-trial, continued access in Investigator-Initiated Trials (IITs) and analyzing the role of the Research Ethics Committee in assessing post-trial continued access to an investigational product.

The development and administration of safe and effective therapeutic products for children is critical to the health of a population. Global innovation in pediatric drug development lags behind adult product development due to myriad practical challenges of executing multi-national clinical trials, regulatory challenges of working across jurisdictions, and ethical challenges of enrolling children in research. As a consequence, pediatric patients are often prescribed therapeutic products for which safety or efficacy information for those age groups and/or those indications is inadequate.
Medicines—including drugs, biologics, and devices—must be more frequently, rigorously, and carefully evaluated for safety and efficacy in the global pediatric population. This vision depends, in part, on identifying and overcoming existing barriers to conducting multi-regional pediatric trials, and then motivating their enrollment, conduct, and completion.
To harmonize approaches globally, the MRCT Center convened a workgroup in 2019 of academia, industry, regulators, non-profits, trial networks, patients, and advocates. With the work ongoing, we are sharing findings and advancing international collaborations. Our resources include the Including Young People in Research toolkit, currently under revision with a release anticipated in early 2026, Guiding Principles, and a curated selection of pediatric-focused webinars, complete with recordings and summaries.
In 2024, we released a comprehensive interactive webpage to summarize the work and link to key deliverables and began exploring pediatric platform trials—studies evaluating multiple investigational products simultaneously. An October 2024 workshop, with 80 global experts, identified gaps and strategies in three disease areas: major depressive disorder, oncology, and multidrug-resistant tuberculosis. In July 2025, a follow-on workshop focused on pediatric oncology met to develop an implementation framework for academic–industry platform studies to support regulatory requirements (PIPs, iPSPs) and potential marketing authorization. That work continues with a number of smaller workstreams developing products that will be collated for dissemination in early 2026.


The moniker “Protocol Ethics” refers to addressing ethical issues in the design of clinical trials and documenting their rationale in a section of the study protocol easily understood by institutional review boards/research ethics committees. Study teams designing and developing clinical trial protocols may benefit from a systematic methodology to ensure that ethical issues have been considered, addressed, and documented appropriately.
Launched in August 2012, this project was driven to ensure that key ethical questions are addressed when navigating the process of designing protocols for multi-regional clinical trials. Released in November 2013, the resulting toolkit defined eleven essential elements that are recommended to be addressed in the design of multi-regional clinical trials. In November 2014, in collaboration with Global Health Network, an e-learning course was launched with the content of the toolkit, which has been utilized by learners around the world.
Given the evolution of clinical trial design and conduct, and the emergence of new considerations, the MRCT Center’s Protocol Ethics toolkit is currently under revision. It aims to ensure key ethical questions are systematically addressed during the design and conduct of multi-regional clinical trials to provide timely and relevant guidance when designing clinical trials.

Derived from data sources such as electronic health records, claims data, registries, and mobile devices, real world evidence (RWE) has the potential to bring innovative products to patients more quickly. Unlike randomized controlled trials (RCTs), which may not be representative of a general population due to strict inclusion and exclusion criteria, RWE may more closely identify how an investigational product will perform in a general population. To address the absence of widely accepted best practices for utilizing RWE, the MRCT Center collaborated with Duke-Margolis Center for Health Policy to define a framework to establish best practices for utilizing RWE for regulatory decision-making.
The MRCT Center also worked with OptumLabs to investigate sources of variability in RWE analysis as applied to replication (emulation) of RCTs. Conceptualized by the MRCT Center and OptumLabs, the Observational Patient Evidence for Regulatory Approval and uNderstanding Disease (OPERAND) Project aimed to understand the sources of variation in design, approach, methodologies, statistical analyses, and decision-making using real world evidence (RWE, specifically claims and EHR data) to emulate phase 3 clinical trials. First, RWE is used to replicate published clinical trials, using and analyzing data limited explicitly to the eligibility criteria of the trial. Later, the aperture of inclusion is broadened to determine any change in effect size by the broader population.
The OPERAND project convened a technical expert panel (TEP) comprising key stakeholders from industry, academia, and regulators, to consider the principles behind, the methodology to draw upon, and the appropriate utilization of, observational data in regulatory review and approval and comparative effectiveness research.
Brown University and Harvard Pilgrim Health Institute, were selected to replicate two trials:
The project helped validate the use of observational data to complement evidence from RCTs and used empirical data to understand methodologies and sources of variability.

Abstract
The exclusion of people with disabilities from clinical research without appropriate justification is discriminatory, is counter to federal regulations and research guidelines, and limits study generalizability. This matter is understudied, and data on the disability status of trial participants are rarely collected or reported. We analyzed ninety-seven recent interventional protocols in four therapeutic areas registered on ClinicalTrials.gov. Eighty-five percent of protocols allowed broad investigator discretion to determine eligibility, whereas only 18 percent explicitly permitted people with disabilities to use forms of support (such as supported decision making or assistive devices) to facilitate study participation. Eligibility criteria affecting people with disabilities included exclusions for psychiatric (68 percent), substance use (62 percent), HIV or hepatitis (53 percent), cognitive or intellectual (42 percent), visual (34 percent), hearing (10 percent), mobility (9 percent), long-term care (6 percent), and speech and communication (3 percent) disability-related domains. Documented justification was provided for only 24 percent of these exclusions. We recommend greater scrutiny of study eligibility criteria, scientific or ethical justification of exclusions, and accessible study design.
