Individualized interventions for rare genetic conditions and the research-treatment spectrum: Stakeholder perspectives.

Purpose: Advances in the study of ultrarare genetic conditions are leading to the development of targeted interventions developed for single or very small numbers of patients. Owing to the experimental but also highly individualized nature of these interventions, they are difficult to classify cleanly as either research or clinical care. Our goal was to understand how parents, institutional review board members, and clinical geneticists familiar with individualized genetic interventions conceptualize these activities and their implications for the relationship between research and clinical care.

Methods: We conducted qualitative, semi-structured interviews with 28 parents, institutional review board members, and clinical geneticists and derived themes from those interviews through content analysis.

Results: Individuals described individualized interventions as blurring the lines between research and clinical care and focused on hopes for therapeutic benefit and expectations for generalizability of knowledge and benefit to future patients.

Conclusion: Individualized interventions aimed at one or few patients reveal the limitations of a binary framing of research and clinical care. As a hybrid set of activities, individualized interventions suggest the need for flexibility and new frameworks that acknowledge these activities across the spectrum of research and clinical care.
