Summary

STRONGER is an international, investigator initiated and conducted, pragmatic clinical trial to determine whether 40mg atorvastatin daily can improve neurocognitive function in adults with long COVID neurological symptoms. The objective is to determine effectiveness of treatment with 40mg atorvastatin over 12 months on attenuating cognitive decline and neuroinflammatory biomarkers in adults with long COVID neurological symptoms. The study design is a prospective, randomised, open-label, blinded endpoint (PROBE) study of atorvastatin 40mg on top of standard care, in patients with long COVID neurological symptoms.

Detailed description

Question: Does treatment with 40mg atorvastatin over 12 months attenuate cognitive decline and neuroinflammatory biomarkers in adults with long COVID neurological symptoms? Aims: In 410 adults who report ongoing alteration of their memory, thinking, concentration or mood after COVID-19 diagnosis, this pragmatic clinical trial aims to determine the effects of standard-dose atorvastatin on improving neurological outcomes with sensitive measures of cognitive function and brain MRI. Outcome measures include; Primary - processing speed, assessed on the oral Symbol Digit Modalities Test (SDMT). Key Secondary - white matter free water measured on diffusion MRI brain imaging. Other - other components of cognitive function; other health assessments; other MRI markers of cerebral white matter integrity, iron load, cerebral perfusion, and glutathione for oxidative stress; cost-effectiveness compared to standard care. The study sites are established at centralised research clinics located at: The Brain and Mind Centre of the University of Sydney; Alfred Medical Centre linked to Monash University, a research clinic associated with Clínica Alemana Universidad del Desarrollo, Santiago, Chile, and a research clinic associated with The Chinese University of Hong Kong. Additional sites may be set up as required.

Conditions

• Neurocognitive Impairment, Mild

Interventions

Type	Name	Description
DRUG	Atorvastatin	40mg atorvastatin + standard care daily for 12 months.Atorvastatin 40mg has TGA approval for general marketing for the treatment of hypercholesterolaemia and cardiovascular prevention under a number of manufacturer names.The study medication selected will be the atorvastatin 40mg (Apotex) which is scored, and allows down-titration to 20mg should a participant develop symptoms.The study medication will be packaged, labelled and dispensed directly to particpants by the Syntro Health pharmacy in Australia. A comparable atorvastatin 40mg is being sourced in Chile, and will be dispensed from the pharmacy of the Clínica Alemana de Santiago. Similarly, a comparable atorvastatin 40mg is being sourced in Hong Kong, and will be dispensed from the site's pharmacy.
OTHER	Standard Care	Standard care for neurological symptoms as a result of COVID-19 infection.
