Introduction to Dalfampridine
Dalfampridine, also known as Ampyra in some markets, is a medication primarily used to improve walking in people with multiple sclerosis (MS). Here, we will delve into the latest clinical trials, market analysis, and projections for this drug.
Clinical Trials and Efficacy
Multiple Sclerosis (MS)
Clinical trials have demonstrated the efficacy of dalfampridine in improving gait speed in people with MS. In Phase 3 clinical trials, dalfampridine showed a significant improvement in the Timed 25-Foot Walk (T25FW) for responders, defined as patients whose gait speed was faster for at least 3 of the 4 on-drug assessments compared to their fastest off-drug assessment. However, only about 38% of patients were classified as responders, with an average T25FW improvement of 25%[1].
A recent study highlighted the benefits of combining dalfampridine with physical therapy. When physical therapy was added to the treatment regimen, all participants showed improvements in T25FW greater than 20%, with some exceeding 30% improvement. This suggests that combining physical therapy with dalfampridine could significantly enhance the responder rate[1].
Spinocerebellar Ataxia (SCA)
Dalfampridine is also under investigation for its potential in treating Spinocerebellar Ataxia (SCA). Currently in Phase II clinical trials, the drug's likelihood of approval and phase transition success rate are being assessed. According to GlobalData, Phase II drugs for SCA have a 29% phase transition success rate, providing a benchmark for dalfampridine's potential progression to Phase III[3].

Safety and Adverse Events
Post-Marketing Surveillance
Post-marketing safety surveillance of dalfampridine has identified several adverse events (AEs). Using the US FDA's Adverse Event Reporting System (FAERS), a study analyzed AE reports from 2010 to 2022 and identified 335 AE signals, including urinary tract infections, dizziness, and condition aggravation. The study also noted that AEs were more common in females and the 45-65 age group, consistent with MS epidemiology[5].
