High-caloric fatty diet for patients with ALS

Efficacy, Safety, and Tolerability of Ultra-high-caloric, Fatty Diet (UFD) in Amyotrophic Lateral Sclerosis (ALS)

Not applicable Interventional University of Ulm · NCT06280079

This study is testing if a high-calorie, fatty diet can help people with ALS live longer and maintain their weight better than a regular diet.

What this trial studies

This study evaluates the efficacy and tolerability of an ultra-high-caloric, fatty diet compared to a placebo in patients diagnosed with amyotrophic lateral sclerosis (ALS). ALS is a severe neurodegenerative condition that leads to muscle paralysis and ultimately respiratory failure. The study aims to improve survival rates by addressing the unique metabolic challenges faced by ALS patients, particularly their increased resting energy expenditure and weight loss. Previous research has indicated that high-caloric diets may prolong survival and reduce weight loss in ALS patients, prompting this investigation.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with a diagnosis of ALS and a disease duration of less than 24 months.

Not a fit: Patients with advanced ALS or those who do not meet the specific inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance survival and quality of life for ALS patients by addressing their nutritional needs.

How similar studies have performed: While previous studies have shown mixed results, some have indicated potential benefits of high-caloric diets in ALS, making this approach both relevant and promising.

Exclusion Criteria:

* Previous participation in another interventional study involving an active treatment within the preceding 4 weeks
* Tracheostomy or continuous permanent ventilator dependence (\>22 hours per day)
* Pregnancy or breastfeeding
* Any medical condition known to have an association with motor neuron dysfunction which might confound or obscure the diagnosis of ALS
* Presence of any concomitant life-threatening disease or impairment likely to interfere with functional assessment.
* Evidence of a major psychiatric disorder or clinically evident dementia precluding evaluation of symptoms.
