Our Work

The N=1 Collaborative is an international network of experts working together to bring individualized treatments to rare disease patients. We are initially focused on the use of antisense oligonucleotides (ASOs) as they are rapidly customizable. Through our efforts with ASOs, we are establishing a standardized framework for individualized medicine that will extend to other customizable platform technologies such as siRNAs, RNA therapeutics, and CRISPR as well.


Multidisciplinary collaboration was vital to making the earliest individualized medicines – milasen, jacifusen, and afinersen – possible. This collaborative ethos continues to be necessary in order to learn and improve.

Seminar Series

Case Conferences & Seminar Series

The N1C Seminar Series will host leading experts in the field to advance important conversations in the personalized medicine space. We feature speakers from academia, industry, and people directly affected by rare disease. The format varies from research talks, to case conferences, to panel discussions. The talks are always open to the entire N1C community, with time allotted for Q&A. If you have ideas or requests for additional topics, please reach out to Erin McConnell at

Flow Chart

Data Coordination

We are establishing databases to make sharing of preclinical and clinical learnings across individualized ASO treatments more efficient. By reducing the barriers to this type of sharing, we can learn and improve. ​
