New Strategies for MPS: A novel approach to address unmet needs in nonsense mutation MPS 1

Basic and bench research. Following the opening remarks, presentations in the morning and afternoon sessions will discuss innovations in technology and how they can be applied to early diagnosis for lysosomal conditions, progress in gene therapy, and exploitation of differences at the cellular level that may indicate early disease state. On Tuesday, the noon hour is reserved for a meeting with the WORLDSymposia Council of Patient Advocates (COPA)™ that focuses on patient involvement in research planning and subject recruitment.

Next Generation for Lysosomal Disorders: Treatments, Biomarkers and Talent Needed to Succeed

Translational research. The second day of the meeting turns to the challenge of moving laboratory discoveries to therapy, the important hurdles of translational research. Some broad topics of discussion include modulation of CNS affects of disease, how to increase the efficacy of therapeutic modalities, and genotype/phenotype correlations.

Clinical research. The entire third day is committed to presentations of results from clinical trials, in most cases, the actual application of new agents in humans affected by these conditions. Day 3 will also include presentations related to re-thinking the definition of biomarkers for lysosomal disease.
