Amyotrophic lateral sclerosis (ALS) has been traditionally considered incurable and untreatable. But starting in the 1990s with the introduction of Riluzole, therapies are being discovered and ultimately approved for slowing disease progression. Many pharmaceutical companies continue to seek new therapeutic approaches. One critical aspect of all clinical trials is the need track to progression sensitively to identify the impact of therapy. Tools to track ALS progression must be convenient, objective, require minimal training, be easily standardized, cost-efficient, and have the potential to be applied effectively at home. There has been a push to identify accurate, objective biomarkers of ALS progression. In this study, the investigators propose to use Electrical impedance myography (EIM) to evaluate the progression of the disease. Work has shown that the EIM 50 kilohertz (kHz) phase value from one or more muscles, followed sequentially, can serve as an effective overall biomarker for assessing the rate of ALS progression for a single person.
NCT06877208
This is a pilot study in which the investigators will investigate the effect of exogenous glucagon on cerebral glucose metabolism in healthy humans. Participants will participate in either part C or part D of the study, and each participant will participate in three study days. During a study day the participant will receive an intravenous infusion of either glucagon, glucose (in an adjustable rate to match to glucose concentrations achieved with the glucagon infusion) or saline. During each study day an 18F-flouro-deoxy-glucose (FDG) Positron Emission Tomography (PET)/Computed Tomography (CT) scan will be performed to quantify cerebral glucose metabolism during the first part (acute effect) of the glucagon/glucose/saline infusion (part C) or the last part (later effect) of the glucagon/glucose/saline infusion (part D).
