OptiCALS RCT

OptiCALS RCT

UK Chief Investigator

Professor Christopher McDermott

Research summary

The purpose of this study is to test a support package (the ‘OptiCALS’ intervention) designed to increase energy available to people living with amyotrophic lateral sclerosis (ALS), also known as motor neuron disease.

Little is currently known regarding how food intake affects ALS and there is a lack of guidance for patients and healthcare professionals on weight and nutrition in ALS. Evidence from some small studies suggests that increasing the available energy for nerve cells may make them more resistant to the degenerative process in ALS. This may lead to a slowing down of ALS progression, improving physical function and quality of life for people living with ALS. However, to work out whether this is true, we need to conduct a large randomised controlled trial, where participants will get the OptiCALS intervention and/or continue with treatment as usual.

The OptiCALS intervention has been designed by a team of MND specialists to help people with ALS receive a tailored, high-energy diet at the most appropriate time, in the most effective manner. The OptiCALS nutritional intervention package is available via an online portal which includes videos, dietary information, advice, and interactive tools designed to assist people with ALS to optimise their nutrition. This will be provided alongside support from a healthcare professional.
