Covid19 | Drug: Fluoxetine Drug: Placebo | Early Phase 1 |
Morbidity and mortality resulting from COVID-19 infections are associated with multisystem organ failure due to a rapid increase in cytokine production. Fluoxetine has been shown to reduce the mechanisms that cause the cytokine storm that leads to COVID-19 fatalities.
This is a pilot study to assess feasibility of recruiting and retaining participants diagnosed with COVID-19. The purpose of this study is to observe the early use of fluoxetine treatments on illness outcome: primary outcome is hospitalization and secondary outcomes of complications including intubation and death. Additional secondary outcomes include effects on outcomes for depression and post-traumatic stress disorder, two common illnesses which may be improved by fluoxetine.

- Rate of hospitalization [ Time Frame: 8 weeks ]Measures number of subjects hospitalized for COVID-19 symptoms
- Physical symptoms assessed through daily checklist [ Time Frame: 8 weeks ]The 23-item daily symptom checklist measures the presence or absence of COVID-related symptoms (e.g. shortness of breath, fever, chills) and other possible symptoms (e.g. ear pain, vomit, seizures).
- Rate of intubation [ Time Frame: 8 weeks ]Measures number of subjects intubated for COVID-19 symptoms
- Rate of death [ Time Frame: 8 weeks ]Measures number of subjects who die from COVID-19 symptoms
- Depressive symptoms assessed weekly [ Time Frame: 8 weeks ]Measured using the 9-item Patient Health Questionnaire (PHQ-9) each item rated on a scale of 0-3, where 0=no depressive symptoms and 3=depressive symptoms present nearly every day. A high score indicates severe depression.
- Post traumatic stress disorder symptoms assessed weekly [ Time Frame: 8 weeks ]Measured using the 4-item SPAN assessment rated on a scale from 0-4 where 0=not at all distressing and 4=extremely distressing. A score greater than 5 indicates the presence of PTSD.
- Anxiety symptoms assessed weekly [ Time Frame: 8 weeks ]Measured using the 7-item General Anxiety Disorder Scale (GAD-7) rated from 0-3, where 0=no anxiety symptoms and 3=anxiety symptoms present nearly ever day. A high score indicates severe anxiety.
- Suicidality assessed daily [ Time Frame: 8 weeks ]Measured using the 6-item Columbia-Suicide Severity Rating Scale (C-SSRS), a semi-structured interview on the presence or absence of suicidal ideation.
