[VIRTUAL] Use of a Novel Bead-based Assay to Measure the Impact of Imlifidase on ABO IgG Antibodies () - May 18, 2021 - Abstract #ATC2021ATC_2168; ABO-Ab isotype differentiation may be particularly relevant in the context of plasmapheresis, commonly used in ABOi transplant, which more efficiently removes IgM Ab than IgG. HA has limitations in monitoring the effectiveness of imlifidase treatment but this bead-based antibody assessment adequately measures the effect of imlifidase and may provide a tool to clarify if there is a role for imlifidase in ABOi transplantation in individuals with high levels of ABO IgG Ab.

Review, Journal: Is it the right time for an infant screening for Duchenne muscular dystrophy? (Pubmed Central) - May 15, 2021 Five to eight DMD subjects are believed to be diagnosed. The pilot project would give the opportunity to test in a small population the feasibility of an infant screening programme, which in the near future could be applicable to an entire country.

Clinical, Journal: Highly sensitive screening of antisense sequences for different types of DMD mutations in patients' urine-derived cells. (Pubmed Central) - May 15, 2021 An essential finding of this study is that the sequence of eteplirsen consistently leads to much lower efficiency than other sequences. These findings underscore the importance of AON sequence optimization by our cellular system, which enables highly sensitive screening of exon skipping drugs that target different types of DMD mutations.

[VIRTUAL] Micro-Dystrophin Gene Therapy Delivery and Therapeutic Plasma Exchange in Non-Human Primates () - Apr 30, 2021 - Abstract #ASGCT2021ASGCT_758; Methods In Part 1, we intravenously (IV) dosed 5 cohorts (n=3 each) of treatment-naïve NHPs at 2x1014 vg/kg titer (supercoiled qPCR titer method) with rAAVrh74.MHCK7.micro-dystrophin (SRP-9001)...Cohort 5 received rituximab, sirolimus and prednisone (14 days pre, 60 days post)...Conclusion These findings establish TPE as a safe and effective strategy for AAVrh74 vector delivery in NHPs. The results may inform human studies of individuals with preexisting immunity.

Journal: Efficient correction of Duchenne muscular dystrophy mutations by SpCas9 and dual gRNAs. (Pubmed Central) - Apr 20, 2021 Based on this predictive repair outcome, efficient in-frame deletion of a part of DMD exon 51 was achieved in HEK293T cells with plasmids expressing SpCas9 and dual gRNAs...Restoration of DMD expression at both the mRNA and protein levels was confirmed in the induced myotubes. With further development, the combination of SpCas9-dual gRNA-corrected DMD patient fibroblasts and transdifferentiation may provide a valuable therapeutic strategy for DMD.

Volanesorsen, another 20-mer MOE gapmer has shown to be successful in lowering the levels of triglycerides (TGs) in several lipid disorders and has received conditional approval in the European Union for the treatment of Familial chylomicronemia syndrome (FCS) in May 2019 following successful results from phase II/III clinical trials. This chapter focuses on the clinical applications of gapmer AOs for genetic dyslipidemia and lipodystrophy.

Clinical, Review, Journal: Clinical Phenotypes of DMD Exon 51 Skip Equivalent Deletions: A Systematic Review. (Pubmed Central) - Mar 9, 2021 No abstract available This review shows that the majority of exon 51 "skip-equivalent" deletions result in milder (BMD) phenotypes and supports that exon 51 skipping therapy could provide clinical benefit, although we acknowledge that other factors, such as age at treatment initiation or ongoing standard of care, may influence the degree of benefit.
