Treating for Life: Why the Data Matters
Nano-rare patients represent the most medically underserved population, and for most, this marks the first time a targeted treatment has ever been available. In this presentation, we examine the critical role of continued engagement with the treating physician and patient after the initial treatment period. We discuss the challenges of collecting and publishing aggregate data, where endpoints may be different among patients and are often dynamic and evolving with treatment. Our longitudinal data are not only essential to guide care for each patient, but also offer unprecedented insights into disease progression and therapeutic response in nano-rare patients. Continued publication of these findings is vital to advancing the science and setting new standards for future individualized treatments.

Opening Remarks – Day 2
Investigator Presentation
Improvement in Developmental Disability from Genetically-targeted Treatments: What Have We Seen?
Dr. Berry-Kravis discusses what has been observed in development disabilities on disease-modifying treatment. Genetic and developmental and intellectual disabilities (ID) have recently been a target for genetically-directed treatments that reverse the disease mechanism. We do not know how much, for which ages of patients, and for which conditions, reversal of the abnormal brain development and function is possible. Additional measurement issues for those with ID make this a complex problem to address. Some headway is gradually being made in this area, however, and it is only by attempting to reverse the cognitive and behavioral deficits in these disorders that we can understand how possible each is to reverse.

‘N of 1‘ to ‘N of a Few‘
The success of n-Lorem’s the N of 1 ASO program leads to the question of what comes after the first patient. If there is evidence of safety and efficacy for the first patient, how do we assess who else might be appropriate for the same ASO and how do we develop standardized protocols and tools to assess efficacy across patients at different disease stages and across different sites?
Presentation
Creating Connectivity: Building a Community for the Nano-rare
Nano-rare patients face profound isolation, not just medically but socially and emotionally. With no patient registries, no disease-specific organizations and often no other known individuals sharing their disease, these patients have had no support networks in the past. We want to change that. This presentation explores how n-Lorem has worked to change the isolation nano-rare patients face. Through intentional efforts, including a dedicated website, robust social media presence, educational podcasts series and a successful patient colloquium. n-Lorem is creating a space for shared experience, trusted information and collective support. We share data demonstrating the growth and engagement of our audience, outline the tools and platforms we use, including our Lessons in Antisense series, and describe how we measure success. From demystifying antisense science to providing practical resources for patients and physicians, our goal is to build an informed and connected community.
Community Panel
Why Community Matters: A Conversation with Nano-rare Patients and Families

The Importance of Understanding Mutation-specific Biology, Exemplified by JIP3
This study highlights the importance of understanding mutation-specific biology, exemplified by a toxic gain-of-function mutation in JIP3 (R578C) that disrupts axonal transport, signaling pathways, and overall neuronal function. By elucidating the molecular proximal pathological mechanisms associated with this mutation, we have successfully identified allele-selective ASOs as the optimal therapeutic strategy.
Phosphorothioate Antisense Oligonucleotide Induced Innate Immune Activation is Terminated by Tryptophan Oxidation Products
Phosphorothioate antisense oligonucleotides (PS-ASOs) can activate the innate immune response via toll-like receptor 9 (TRL9), creating safety challenges in the clinic. Our research has uncovered how the PS-ASO-induced innate immune response is terminated. This work significantly advances our understanding of PS-ASOs, enabling the development of drugs that are better tolerated to improve outcomes for patients.
DYRK1A, a Discovery Case’s Evolution from Research to High-throughput Scalability
The current DYRK1A program has evolved from designing a small number of candidate ASOs to leveraging n-Lorem’s high-throughput n-of-1 Discovery pipeline. This work has enabled us to conduct rapid, rigorous and high-quality screening combined with functional studies to specifically target the pathogenic mechanism of this nano-rare disorder.
Progress in Creating Agonist-like ASOs for Patients with LOF Mutations
Building on foundational work from the Crooke lab and integrating our own AI-driven algorithm, we have developed a platform to identify and validate genomic regulatory elements that can be targeted by ASOs to upregulate protein expression. This therapeutic strategy has now established proof of concept protein upregulation and addresses haploinsufficiency and loss-of-function diseases through a mutation-independent approach, broadening its applicability across diverse patient populations.
Using ‘Omics’ Data to Inform and Refine ASO Design
This study illustrates how we apply our experience and deep expertise to harness insights from large-scale public genomic and transcriptomic datasets to inform multiple stages of ASO discovery; from feasibility assessment to design and optimization. We will also discuss the critical importance of selecting appropriate datasets to support informed and effective decision-making throughout this process.
Robust Safety Monitoring in n=1 Trials: A Scalable Approach from REDCap to PowerBI for Data Safety Monitoring Board Oversight
We present a scalable data lifecycle framework for n=1 trials, designed to support robust safety monitoring and Data Safety Monitoring Board (DSMB) review. Beginning with individualized protocol development, the workflow moves to custom REDCap electronic data capture (EDC) builds, remote data monitoring and cleaning, and direct export of cleaned data into PowerBI. Our PowerBI dashboards enable real-time, visualized safety review across adverse events, concomitant medications, labs, and other key safety measures.
From Sequence to Safety: Preclinical Assessment of Tolerability and Toxicology Profiles of ASOs
At n-Lorem, patient safety is the foundation of our discovery and development process. The development of optimal experimental ASOs depends on achieving excellent safety profiles, guided by rigorous tolerability and toxicology assessments throughout. This poster outlines n-Lorem’s comprehensive preclinical development approach for creating well-tolerated ASOs with favorable toxicological profiles. It will detail standard class-related in vivo findings, the primary types of toxicities encountered, and key safety considerations at each stage of preclinical development.
Ensuring Quality at Every Step in our ASO Manufacturing and Formulation
Our approach to antisense oligonucleotide (ASO) manufacturing ensures rigorous quality control from lead identification through GMP production. This poster outlines how, once a lead ASO is selected, we assess key development risks and timelines to inform the strategy for GMP drug substance manufacturing—either in parallel with or following toxicology batch production. The selected sequence is transferred to the drug substance CMO, and documentation preparation begins. The GMP process involves several steps: amidite preparation, solid-phase synthesis, cleavage and deprotection, purification, ultrafiltration, and lyophilization. GMP drug substance is then transferred to the drug product CMO where it is further processed through formulation, sterile filtration, and filling into ready for dosing vials. Quality is ensured through comprehensive analytical testing, including HPLC purity/impurity profiling, sterility assessment and annual stability testing. These activities are executed in close partnership with trusted CDMOs to ensure consistency and compliance with regulatory standards.
ASO Discovery, Development, and Clinical Operations: A Patient and Physician Perspective
n-Lorem and each physician and institution has many critical responsibilities throughout the n-Lorem process and makes significant financial investments in each patient’s program. This poster will outline n-Lorem’s operational processes to support and guide physicians through n-Lorem’s unique framework. These proactive steps which begin prior to patient nomination and continue through patient treatment, are designed to increase the efficiency of and reduce administrative hurdles for each patient program.
Tackling RNA-caused Diseases: A Focus on RNU4-2
Mutations in U-rich RNAs are increasingly recognized as drivers of neurodevelopmental disorders. Although their short length and structured nature presents challenges, ASO technology offers a unique therapeutic opportunity. This work focuses on a recently identified mutation in RNU4-2, highlighting its functional characterization and n-Lorem’s therapeutic strategy to address its toxic effects.
iPSC Strategies to Reduce Time and Cost in Disease Modeling
This work describes the establishment of an optimized iPSC-derived neuronal differentiation platform to streamline disease modeling for ASO screening. By utilizing patient-specific iPSCs, this approach offers a scalable, robust, and cost-effective solution for high-throughput ASO screening, significantly reducing timelines and costs in the preclinical discovery pipeline. Craig McIntosh, Ph.D., will be presenting on behalf of Ria Thomas, Ph.D.
