Clinical Trial Summary

Purpose: To decrease symptom burden, improve cognitive function, improve endurance, and decrease fatigue in subjects with post-acute sequelae of COVID-19 (PASC) or "long-hauler" COVID using amantadine. If amantadine use is determined to be efficacious in this population, the findings of this study will be used towards a subsequent randomized control trial.

Description:

This study is a prospective, open-label, single-blind, randomized control study. Study duration is approximately 6 weeks starting at the baseline visit. We will recruit 30 participants (15 per arm) for this pilot study.

• Confirmed COVID+ test (either rapid antigen or PCR) between 8 weeks and one year prior to initial visit.
• Able to consent in English
• Endorse symptoms during their initial evaluation and history with the provider that began around the time of the acute COVID19 infection (subjective) including cognitive changes such as cognitive fatigue, brain fog, memory issues,attention issues AND have

symptoms in at least 1 out of the 2 following symptom categories:

• Category 1: Decreased endurance, physical fatigue, weakness
• Category 2: Depression, anxiety

impairment in the opinion of the investigators, including but not limited to:

• Suicidality
• Neurologic:
• Epilepsy
• Cognitive dysfunction predating COVID infection
• History of delirium

Related Conditions & MeSH terms

• Cognitive Dysfunction
• Long COVID

Intervention

Drug:
• Amantadine
Participants that have been randomized to the study group will be instructed to begin taking amantadine on the day after this study visit. They will self-administer amantadine 100 mg twice daily (morning and noon) for four weeks

Other:
• Physical, Occupational, Speech Therapy
Physical Therapy (PT) and Occupational Therapy (OT) train patients on breathing exercises and gradual reconditioning. Patients are referred to speech therapy (SLP) for cognitive remediation and metacognitive strategies.
• Provider Counseling
Clinic providers will provide counseling/education on Long-COVID.
• Medications for symptoms management
Clinic providers may recommend targeted pharmacologic management for symptoms the patient is experience. As an example, if a patient reports a headache the provider may recommend over-the-counter or prescription medications to target this particular symptom.
