Primary lateral sclerosis (PLS) is a rare neurodegenerative disorder primarily affecting the upper motor neurons. People living with PLS experience progressive physical and communication disability, which typically evolves slowly over several years. In contrast to amyotrophic lateral sclerosis (ALS), life expectancy is anticipated to be normal. Disease-modifying medications are not available and PLS drug development has been challenging. This review considers recent advances and ongoing initiatives aimed at promoting clinical trial readiness for PLS. Ongoing clinical research efforts include patient registries and biorepositories, natural history studies, outcome measure validation, and biomarker development. These international collaborative efforts are essential for developing the first therapeutic trials for people living with PLS.
