Neurology: Disease Deep Dive

How quickly does fenfluramine improve seizure control in patients with Lennox-Gastaut syndrome (LGS), and how do its efficacy and safety outcomes evolve over time? In this episode, Amélie Lothe, PhD, Global Medical Head, Rare Epilepsies and Neurodevelopmental Disorders, UCB, and coauthor of a recent study published in Epilepsia Open, discusses findings from a post hoc analysis of a phase 3 fenfluramine clinical trial and its open-label extension.

Andrew Blumenfeld, MD, Cedars-Sinai Neurology, Los Angeles, CA, discusses the updated American Academy of Neurology and American Headache Society guideline on preventive migraine therapy, including the growing emphasis on shared decision-making, the role of CGRP-targeted therapies, and balancing efficacy with tolerability. He also examines how clinicians can assess meaningful treatment response beyond migraine frequency and explores emerging approaches to prevention, including combination therapies and novel therapeutic targets.

Daniel Ontaneda, MD, PhD, Cleveland Clinic, Cleveland, OH, explains why traditional labels such as relapsing-remitting, secondary progressive, and primary progressive multiple sclerosis (MS) may not fully reflect the underlying biology of the disease and why a more dynamic framework could better capture how MS changes over time.

Hubert Fernandez, MD, Cleveland Clinic, Cleveland, OH, discusses findings from the TEMPO trials evaluating tavapadon, a selective dopamine D1/D5 receptor partial agonist, as monotherapy in early Parkinson disease and as an adjunct to levodopa in patients with motor fluctuations. He examines efficacy, tolerability, adverse events, and where tavapadon could fit within the evolving Parkinson disease treatment landscape.

In this episode, Patrick J. Strollo Jr, MD, FACP, FCCP, FAASM, of the University of Pittsburgh Department of Medicine, Pittsburgh, PA, discusses the data from the phase 3 SynAIRgy clinical trial for AD109, an investigational once-nightly oral treatment targeting neuromuscular dysfunction in obstructive sleep apnea, and its potential role in a more personalized approach to OSA care.
