Phase II and III randomized controlled trials (RCTs) have demonstrated AHSCT's superiority in reducing relapse rates and delaying disability progression compared to standard DMTs. Despite the evolution of treatment guidelines, questions persist regarding patient selection criteria and optimal conditioning regimens. Notably, ongoing clinical trials in the United Kingdom, the United States, Italy, and Norway aim to address these uncertainties by evaluating the safety, efficacy, and long-term outcomes of AHSCT vs. high efficacy DMTs in both DMT-experienced and treatment-naïve patients with active RRMS or aggressive multiple sclerosis (MS). These trials promise to provide valuable insights into the positioning of AHSCT within the treatment landscape of MS.
