Watch #ASGCT22 Sessions On Demand Through June 19
Hello, ASGCT Members!
I hope you’re all doing well. For those of you who don’t know me, my name is Hans-Peter Kiem, and I’m incredibly grateful to serve as ASGCT president for the upcoming year! I’m a professor of medicine and pathology at the University of Washington and the director of the stem cell and gene therapy program, as well as the Stephanus Family Endowed Chair for Cell and Gene Therapy, at the Fred Hutchinson Cancer Center. At ASGCT, I’ve been a Member for over 20 years and have served on more than a handful of committees. I’m looking forward to meeting and working with many of you over the next year to implement new ASGCT initiatives and programs.
I’m sure I’m not the only one still thinking about all the phenomenal research and the insightful discussions from last month’s Annual Meeting. After two years of online events, it was such a joy to be together again in person. I’m proud to report that our first meeting in a convention center was our largest yet with more than 7,500 attendees! Please remember that you can watch most of the sessions on demand through June 19 on the virtual meeting platform, and you can still register through that date as well. Thank you to everyone who made this meeting such a huge success!
Finally, we are officially into award season at ASGCT! This year, ASGCT Members can apply through August 1 for more than $1 million in funded awards. We’re offering $100,000 each to six Members working toward career independence in the field through our Career Development Awards (CDA) program, and the Cystic Fibrosis Foundation will support three more $100,000 CDA awards. We’re also offering three Diversity, Equity, & Inclusion Award (DEI) opportunities for Members who are part of underrepresented populations or are researching conditions that disproportionately affect minority populations. If you know anyone who you think might be interested in these opportunities, please pass this information along and make sure they are a Member of ASGCT.
Thank you for giving me the opportunity to serve as president this year, and I’m excited to work with many of you soon.
Sincerely,
Hans-Peter Kiem, MD, PhD
ASGCT President

Deepm5C: A deep-learning-based hybrid framework for identifying human RNA N5-methylcytosine sites using a stacking strategy

Summary by Edith Pfister, PhD
RNA modifications can affect RNAs' localization, accessibility, stability, or structure. Researchers have identified hundreds of RNA modifications; 5-methylcytosine (m5C) is a common RNA modification found in a variety of types of RNA, including ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), messenger RNAs (mRNAs), and non-coding RNAs (ncRNAs). The m5C modification is dynamically regulated, and in mRNA, m5C modification can influence RNA stability, expression, and protein synthesis. Several antibody-based methods for transcriptome-wide mapping of m5C sites exist*, however computational prediction methods have largely been optimized to detect human m5C sites and are less advanced. In a paper in Molecular Therapy, Hasan et al. have developed and validated a deep learning-based method for predicting m5C sites.
Deep learning is a type of unsupervised machine learning; the learning process involves extracting features from a training dataset by iterating over levels of increasing abstraction, much as children do when learning language. This process allows the program to learn the important features that define a true m5C from a biological dataset. A variety of variables can influence the accuracy of the resulting predictor, including how the data is encoded and exactly what type of model is used. The authors tested four methods of encoding and eight different models. To go a step further, they combined the best single models using a method called stacking. The stacking algorithm involves learning how best to combine and harness predictions from multiple models. The authors show that this method outperforms any of their single models and several established algorithms. This method represents an improvement over existing predictors and can likely be used to examine other types of modifications.

Highlights from Annual Meeting Policy-Focused Programming
Newborn Screening Workshop & Podcast on System Modernization
Speakers during the Pre-meeting Workshop Newborn Screening: Toward a System That Keeps Pace with Gene Therapy Advances debated challenges and solutions to the current newborn screening (NBS) system, given the anticipated wave of innovative therapy approvals. They discussed a host of issues surrounding the RUSP and NBS process, and emphasized the need for modernization. Specific topics included hastening state uptake of newly approved conditions, addressing the challenges of data collection via NBS pilot programs, and evaluating emerging screening and clinical programs.
ASGCT has been active in the NBS space since the Society’s current strategic plan took effect in 2020. The Policy and Advocacy team recently sat down with the Newborn Screening Translational Research Network to discuss some of the same issues raised in the NBS workshop. ASGCT’s Senior Manager of Government Affairs, Christina Mayer, details how gene therapy advocates can work to advance the newborn screening system in this podcast episode.
Peter Marks, Ana Hidalgo-Simon Pose Solutions to Development Challenges
On the second day of the Annual Meeting, audience members stepped up to the mic to ask high-level EMA and FDA regulators about regulatory barriers to gene and cell therapy development. Manufacturing challenges took center stage as Drs. Peter Marks and Ana Hidalgo-Simon outlined the need for platform approaches and global harmonization. For regulators specifically, one of these challenges has been changing or inconsistent manufacturing approaches throughout a product lifecycle, making comparability difficult at different stages in development.
Marks and Hidalgo-Simon also shared their thoughts on potential solutions to some of these barriers. Both regulators supported a gene therapy “playbook” approach to standardize early and late-stage manufacturing across products. Marks pointed to the Bespoke Gene Therapy Consortium, of which ASGCT is a member, as an example of the NIH’s commitment to the future of platform technologies.
In addition, audience members asked several questions about the accelerated approval pathway and its applications to gene therapies. The discussion between regulators pivoted to the use and importance of surrogate endpoints, urging early communication with FDA and EMA around the use of endpoints and their evidence of clinical benefit. Marks specifically addressed the communication concerns over OTAT staffing as the number of submitted INDs is expected to increase.
Assessing Ethical Considerations on CGT for Human Enhancement
Speakers during The Ethical Gray Zone? Perspectives on the Development and Governance of Gene and Cell Therapies for Human Enhancement considered a range of questions in the public and professional policy discussions of human genetic modification. Such discussions have traditionally drawn a line at going beyond the treatment of serious disease to attempt to improve on normal human traits within particular social contexts. Recent waves of reports addressing human genome editing concur with that context, even while they acknowledge the theoretical difficulties of defining the “treatment vs. enhancement” line clearly in specific cases. This symposium dived into the myriad considerations that the public dialogue on this issue must address, with the goal of supporting a responsible framework for this research frontier. Case studies in this session provided insight into cultural considerations and the role of governance, and offered a survey of the path leading to human enhancement. Registered attendees can watch the full session on demand to help answer some of these pervasive ethical questions for the field and to better understand the broader context of the “enhancement” debate around gene editing and new gene therapy applications.
Registered attendees can watch all sessions on demand through June 19. Not yet registered? Register here for access to Annual Meeting content.
