“I think that clinical care and the advances in diagnostic testing have transformed the opportunities. I look back 5 years; I would have been a pessimist looking forward at the [limb girdle muscular dystrophy] field.”

Limb-girdle muscular dystrophy (LGMD) Type 2I is caused by biallelic partial loss-of-function of the FKRP gene, which results in hypoglycosylation of alpha-dystroglycan (αDG).1 One of the therapies that is being developed for LGMD Type 2 is called BBP-418, which is an orally administered therapy intended to saturate the partially functional FKRP enzyme, driving increased glycosylation of αDG.

Douglas Sproule, MD, MSc, and colleagues presented preliminary results from a phase 2 study (NCT04800874) of BBP-418 for LGMD2I at the annual Muscular Dystrophy Association (MDA) Clinical & Scientific Conference, held in Dallas, Texas, March 19-22, 2023. Investigators intended to assess the safety and tolerability of BBP-418 as well as the feasibility and usefulness of clinical efficacy and pharmacodynamic (PD) assessments in patients.

Sproule, chief medical officer at ML Bio Solutions, sat down with NeurologyLive® in an interview at the conference to talk about the recent advancements in clinical care with neuromuscular diseases including LGMD. He also spoke about molecular testing for diagnosis in LGMD. In addition, he talked about the pathway to treatments such as the development of gene therapies and how industry partners help move the field forward in research.
