Fluvoxamine for Early Treatment of Covid-19 (Stop Covid 2)

Completed · Phase 3 · Has a placebo group

Conditions studied: Covid19, Coronavirus

In brief

The purpose of this research study is to determine if a drug called fluvoxamine can be used early in the course of the COVID-19 infection to prevent more serious complications like shortness of breath. Fluvoxamine is an anti-depressant drug approved by the FDA for the treatment of obsessive-compulsive disorder. The use of fluvoxamine for the treatment of COVID-19 is considered investigational, which means the US Food and Drug Administration has not approved it for this use. This study is fully-remote, which means that there is no face-to-face contact; study materials including study drug will be shipped to participants' houses. People around the United States and Canada can participate.

Who can join

Age: 30 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Men and woman age 30 and older;
• Not currently hospitalized
• Proven SARS-CoV-2 positive (per lab or physician report).
• Currently symptomatic with one or more of the following symptoms: fever, cough, myalgia, mild dyspnea, chest pain, diarrhea, nausea, vomiting, anosmia (inability to smell), ageusia (inability to taste), sore throat, nasal congestion.
• Able to provide informed consent.
• Upon initial screening, participant reports one of the following risk factors for clinical deterioration: age≥40, racial/ethnic group African-American, Hispanic, or Native American (including more than one race), or 1+ of the following medical conditions which increase risk for developing moderate-severe COVID illness: obesity, hypertension, diabetes, heart disease (coronary artery disease, history of myocardial infarction, or heart failure), lung disease (eg asthma, COPD), immune disorder (eg rheumatoid arthritis, lupus).

You may not qualify if…

• Illness severe enough to require hospitalization or already meeting study's primary endpoint for clinical worsening (eg current O2 saturation <92% on room air, current use of supplemental oxygen to maintain O2 saturation ≥92%).
• Unstable medical comorbidities (eg decompensated cirrhosis), per patient report and/or medical records.
• Immunocompromised from the following: solid organ transplant, BMT, high dose steroids (>20mg prednisone per day), or tocilizumab
• Already enrolled in another COVID 19 medication trial (not including vaccination or prophylaxis trials)
• Unable to provide informed consent
• Unable to perform the study procedures
• Taking donepezil (rationale: donepezil is a S1R agonist), or sertraline (rationale: sertraline is a strong sigma-1 antagonist).
• Taking warfarin-also known as Coumadin (rationale: increased risk of bleeding), phenytoin (rationale: fluvoxamine inhibits its metabolism), clopidogrel (rationale: fluvoxamine inhibits its metabolism from pro-drug to active drug which raises risk of cardiovascular events), and St John's wort (rationale: fluvoxamine + St John's wort are considered contraindicated because of the risk of serotonin syndrome)
• Taking SSRIs, SNRIs, or tricyclic antidepressants, unless these are at a low dose such that a study investigator concludes that a clinically significant interaction with fluvoxamine (ie either serotonin syndrome or TCA overdose) is unlikely (examples: participant takes escitalopram but only at 5-10mg daily; that dose plus 200mg fluvoxamine would be insufficient to cause serotonin syndrome; or, participant takes amitriptyline but only at 25mg nightly; even if fluvoxamine inhibits its metabolism, it would be an insufficient dose to cause QTc prolongation or problematic side effects).
• Individuals who report they have bipolar disorder or are taking medication for bipolar disorder (lithium, valproate, high-dose antipsychotic), unless the investigator concludes that the risk for mania is unlikely (ie it is doubtful that the patient actually has bipolar disorder).
• Individuals who take alprazolam or diazepam and are unwilling to cut the medication by 25% (rationale: fluvoxamine modestly inhibits the metabolism of these drugs).
• Participants taking theophylline, tizanidine, clozapine, or olanzapine (drugs with a narrow therapeutic index that are primarily metabolized by CYP 1A2, which is inhibited by fluvoxamine) will be reviewed with a study investigator and excluded unless the investigator concludes that the risk to the participant is low (this would be unlikely; example: participant takes tizanidine only as needed and is willing to avoid it for the 15 days of the study).
• Received vaccine for COVID-19.
