Clinical Trial Summary

This study aims at evaluating efficacy and tolerability of an ultra-high-caloric, fatty diet (UFD) compared to placebo in patients with amyotrophic lateral sclerosis (ALS).


Clinical Trial Description

ALS is a fatal neurodegenerative disease, leading to progressive paralysis of voluntarily innervated muscles and to death caused by respiratory failure after a mean disease duration of 2-4 years.The proposed study aims at improving survival of ALS patients by targeting metabolic parameters. ALS patients feature an intrinsic hypermetabolism as signified by an increased resting energy expenditure, which significantly contributes to progressive weight loss and cachexia. The extent of weight loss is an independent prognostic factor for survival in ALS. It has been shown that survival of ALS mice can be prolonged by applying a high-caloric nutrition. Furthermore, ALS patients feature distinct alterations of lipid metabolism, and various studies suggest a protective effect of high triglyceride serum levels. In the precursor-study LIPCAL-ALS-I, a randomized, placebo-controlled, multicenter trial, evaluating the effects of a high-caloric fatty diet (HCFD), the primary endpoint (survival in the whole study population) was missed. However, post-hoc analysis revealed showed that HCFD (1) increased survival and reduced weight loss in normal to fast-progressing patients (patients with a functional decline measured by ALS Functional Rating Scale Revised) above the median at baseline; p=0.02), (2) slowed down functional decline (measured by Amyotrophic Lateral Sclerosis Functional Rating Scale Revised) in the whole study population (p<0.0125), and (3) lowered neurofilament light chain (NfL) serum levels as a prognostic biomarker in the whole study population (p=0.0225). Therefore, this study aims at prolonging survival in ALS patients by applying 1.5-fold dosage of the same intervention as in LIPCAL-ALS I in a larger number of patients, excluding patients with slow disease progression. ;
