Clinical Trial Summary

Long COVID, also referred to as post-acute sequela of COVID-19 (PASC), is present in a substantial number of individuals, and treatment for this is warranted. Two different hypothetical models of Long COVID suggest attenuated mitochondrial energy production and psychosocial load, respectively, to be key mechanisms in the underlying pathophysiology. Given the potential importance of metabolic disturbances, dietary supplement by Nicotinamide Riboside (NR, sales name Niagen®) may be beneficial. Given the potential importance of psychosocial factors, a tailored and personalized Mind-Body Reprocessing Therapy (MBRT) may be beneficial. The MBRT consists of 4 to 6 face-to-face therapist encounters in combination with digital resources.

The primary objective is to determine whether NR 1000 mg twice daily and/or MBRT increase health-related quality of life in individuals with Long COVID compared with care as usual and/or placebo. The Medical Outcome Study 36-item short form (SF-36), general health subscore is the primary endpoint. Secondary endpoints are: Markers of inflammation (hsCRP) and cognitive function (digit span test), cost-effectiveness, and the patient-reported symptoms fatigue, dyspnoea, and global impression of change in symptoms, function and quality of life. Explorative objectives encompass intervention effects on additional cognitive function markers, biological markers (indices of autonomic nervous activity), disability markers (work attendance) and patient symptoms, as well as the exploration of long-term effects, differential subgroup effects, intervention effect mediators and intervention effect predictors.

The study is a randomized controlled trial featuring a 2 x 2 factorial design where MBRT is compared with usual care and NR is compared with placebo. The latter comparison is double blinded. Eligible participants are individuals (18-70 years) with confirmed Long COVID interferring negatively with daily activities. A total of 310 participants will be enrolled. After baseline assessment (T1), the participants will be randomized 1:1 for both treatment comparisons, resulting in four treatment groups: a) MBRT and NR; b) usual care and NR; c) MBRT and placebo; d) usual care and placebo. All treatments last for three months, followed by primary endpoint assessment (T2). Total follow-up time is 12 months (T3). A comprehensive investigational program at all time points includes clinical examination, functional testing (spirometry, autonomic cardiovascular control, neurocognitive functions), sampling of biological specimens (blood) and questionnaire charting (background/demographics, clinical symptoms, psychosocial factors, study events).
