Genetic Therapies for Rare Diseases: Developing Ethical Regulatory Policies

Publication

Published on: March 12, 2026

Published in: Hastings Bioethics Forum

Description: In “Genetic Therapies for Rare Diseases: Developing Ethical Regulatory Policies,” a commentary published in the Hastings Bioethics Forum, Carolyn Riley Chapman, former lead of the MRCT Center’s Cell and Gene Therapies project, and co-author Nirvan Bhatia argue that the U.S. should adopt a differentiated approval system for gene-based therapies for rare diseases, conferring different tiers of regulatory approval based on different levels of evidence. The authors contend that this approach would improve patient access to innovative therapies while increasing transparency about evidentiary standards and providing stronger incentives for timely post-marketing studies. The MRCT Center’s Toolkit for Supporting the Design and Conduct of Long-Term Follow-Up Studies for Gene Therapies, released in January, offers practical guidance on related challenges in gene therapy research.

Deploying Digital Twins and Synthetic Data in Evidence Generation

Webinar

Presented on: March 19, 2026

What does it take to deploy digital twins and synthetic data in clinical evidence generation — and what do regulators expect when you do?

In this third webinar in the MRCT Center’s Digital Twins and Synthetic Data series, a multidisciplinary panel examines the real-world application of these technologies across the clinical trial lifecycle. The discussion covers evidence quality and validation, regulatory benchmarks, model transparency, and the evolving landscape of FDA and EMA expectations. Panelists draw on experience spanning machine learning, FDA policy development, and drug development leadership to offer practical, grounded perspectives on what adoption looks like today — and where the field is headed.

Topics include:

  • Defining digital twins and synthetic data: key distinctions and appropriate uses
  • Reducing control arms and enhancing statistical power in randomized and single-arm trials
  • Applications across rare disease, oncology, and common conditions
  • Machine learning vs. traditional statistical approaches: complementary, not competing

A Framework for AI Adoption and Oversight in Clinical Research

Characterization of Key Information Sections in Informed Consent Forms Posted on ClinicalTrials.gov 

Publication

Published on: August 14, 2023

Published in: Journal of Clinical and Translational Science

Abstract: Barbara Bierer and MRCT Center colleagues Walker Morrell, Ava Glazier, and Deborah Zarin, together with Luke Gelinas of Advarra and Tony Tse of the National Institutes of Health, published Characterization of Key Information Sections in Informed Consent Forms Posted on ClinicalTrials.gov in the Journal of Clinical and Translational Science. The 2018 revised Common Rule requires informed consent forms to open with a “concise and focused” key information (KI) section, but provides no guidance on content or format. Analyzing federally funded treatment trial ICFs posted on ClinicalTrials.gov, the authors found that three-quarters included an identifiable KI section averaging one page—yet readability showed little improvement over full ICFs, and a meaningful minority omitted core content such as the main reasons to join or not join a study. The authors call for consensus-based guidelines to help researchers and IRBs develop KI sections that are both compliant and genuinely useful to participants.

Long-Term Follow-Up for Gene Therapies: Key Deliverables and the Path Forward 

Video

Presented on: October 22, 2025, at the MRCT Center Annual Symposium

Long-Term Follow-Up (LTFU) studies are critical for understanding the long-term safety and risk/benefit profile of innovative cell and gene therapies. Study participants, patients, treating clinicians, companies, regulators, payers, and society-at-large all derive different value from LTFU studies. However, these studies present unique challenges due to their unprecedented duration. For sponsors, they are challenging and expensive to design, conduct, and operationalize. For patients, LTFU participation can be burdensome in terms of time, expense, and opportunity costs.

In this recorded panel, which was held during the MRCT Center’s Annual Symposium in October 2025, Dr. Carolyn Chapman describes the aims of the Center’s LTFU Working Group, which was launched in September 2024 and benefited from the perspectives of 25 members from outside the Center.  Dr. Chapman also previews the release of the LTFU Toolkit, which was collaboratively developed by the Working Group. The Toolkit offers practical guidance to support best practices for LTFU studies for both investigational and approved gene therapies.

In this session, Dr. Chapman leads a discussion with three distinguished industry leaders on a variety of issues addressed in the LTFU Toolkit. These include integrating decentralized elements to reduce burden, refining endpoint selection, harmonizing data for interoperability across LTFU studies, and minimizing loss to follow-up through participant engagement and clear communication. They also highlight the need for flexibility in LTFU study designs to meet evolving patient needs, and the importance of keeping new and current participants informed about protocol changes and any key findings. Looking ahead, the group calls for ongoing dialogue on data harmonization and sharing, results transparency, and innovative approaches to streamline the collection of long-term safety information.
