About this study

Official title: Fluvoxamine to Augment Olfactory Recovery For Long COVID-19 Parosmia (FluCOP Trial)

This study will investigate the efficacy of oral fluvoxamine in olfactory improvement following Covid-19- associated parosmia. This is a randomized, double-blinded, placebo-controlled trial.

Read the detailed description

The drug will be given over a 14 weeks with six weeks titrating up, six weeks maintaining highest dose, and up to two weeks tapering down. Assessments will be collected following week 12 to measure change in olfactory function from baseline between the two study groups.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FluvoxamineDrug

    Also called Luvox

    Fluvoxamine is an SSRI used for depression and anxiety disorders. This study will investigate the efficacy of fluvoxamine for improvement of olfactory dysfunction in subjects with post-Covid-19 parosmia.

  • PlaceboDrug

    lactose placebo capsules identical to fluvoxamine capsules in order to preserve blind

Study groups in NCT05216614
Study groupRoleWhat they receive
FluvoxamineExperimentalThis arm will be given the active treatment, oral fluvoxamine capsules of 25 mg each. The first six weeks will be gradual titration (weeks 1 \& 2 25mg BID, weeks 3 \& 4 75mg BID, weeks 5 \& 6 100mg BID). The following six weeks will be fixed dose of 100mg TID. The last two weeks will be a taper down (first week 50mg BID and second week 25mg BID) There will be 14 weeks of active treatment and assessments will be conducted after completion of week 12, prior to beginning taper down period.
Receives: Drug: Fluvoxamine
PlaceboPlacebo comparatorPlacebo capsules that look, smell, and taste like fluvoxamine capsules will be given to the placebo arm. To preserve double-blinding of the study, subjects will receive one capsule BID during the first six weeks following the titration schedule and one capsule TID during the next six weeks for the fixed-dose period. Subjects will then taper-down placebo to imitate the fluvoxamine arm for two weeks. Assessments will be conducted at 12 weeks following completion of fixed-dose period, prior to starting taper down period.
Receives: Drug: Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical Global Impression Scale (CGI)

    The CGI has two components - the CGI-Severity and the CGI-Improvement.

    Scores on the CGI-Severity Scale range from 1 to 7 (1 is Normal, 7 is Complete loss of smell) and provide information on the patient's perceived severity of their dysfunction at baseline. The score on the CGI-Improvement Scale ranges from 1 to 7 (1 is Very Much Improved, 7 is Very Much Worsened). Each rating is well defined to maximize accuracy. Participants reporting 3 as Minimally Improved, 2 as Much Improved, or 1 as Very Much Improved in the CGI-I will be deemed responders to treatment, and the number of responders to non-responders will be compared between the two arms.

    The Clinical Global Impression-Severity Scale for Parosmia (CGI-P) will also be used. The CGI-P Scale ranges from 1 to 5, where 1 is No Distortion, 2 is Mild Distortion, 3 is Moderate Distortion, 4 is Mostly Distorted, and 5 is Complete Distortion.

    Measured: CGI-S and CGI-P will be administered at Baseline and Week 12 after completion of fixed-dose period, prior to taper down, to measure change. CGI-I will be administered at Week 12 after completion of fixed-dose period, prior to taper down

Secondary outcomes (5)
  1. University of Pennsylvania Smell Identification Test (UPSIT)

    The UPSIT is composed of 40 strips of microencapsulated odorants, which are present on the bottom of each page, just below a four-alternative multiple-choice question. For a given item, the patient releases an odor by scratching the microencapsulated pad with a pencil tip, smells the pad, and indicates the odor quality from four alternatives. Even if no smell is perceived, a response is required (i.e., the test is forced-choice). The subject's total correct score out of the 40 items is determined and provides an objective measure of olfactory function.

    Measured: Baseline and Week 12 after completion of fixed-dose period, prior to taper down, to measure change from baseline

  2. Olfactory Dysfunction Outcomes Rating (ODOR)

    The ODOR questionnaire is a 28-item disease-specific health status survey to assess the physical problems, functional impairments, and emotional consequences secondary to olfactory dysfunction. ODOR was developed and validated by Dr. Jake Lee and colleagues in the Clinical Outcomes Research Office at Washington University

    Measured: Baseline and Week 12 after completion of fixed-dose period, prior to taper down, to measure change from baseline

  3. The Depression, Anxiety and Stress Scale - 21 Items (DASS-21)

    The DASS-21 is a set of three self-report scales designed to measure the emotional state of depression, anxiety, and stress. Each of the three DASS-21 scales contains 7 items, divided into subscales with similar content. The depression scale assesses dysphoria, hopelessness, devaluation of life, self-deprecation, lack of interest / involvement, anhedonia and inertia. The anxiety scale assesses autonomic arousal, skeletal muscle effects, situational anxiety, and subjective experience of anxious affect. The stress scale is sensitive to levels of chronic non- specific arousal and assesses difficulty relaxing, nervous arousal, and being easily upset / agitated, irritable / over-reactive and impatient. Scores for depression, anxiety and stress are calculated by summing the scores for the relevant items.

    Measured: Baseline and Week 12 after completion of fixed-dose period, prior to taper down, to measure change from baseline

  4. The Smell Catastrophizing Scale (SCS)

    The SCS is a 13-item scale that asks the participants to describe the degree to which they have specific thoughts and feelings as a result of their sense of smell problems.

    Measured: Baseline and Week 12 after completion of fixed-dose period, prior to taper down, to measure change from baseline

  5. 36-Item Short Form Health Survey (SF-36)

    The SF-36 is a 36-item questionnaire evaluating physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. This test allows us to study the general health overall quality of life changes for those suffering from COVID-19 related OD.

    Measured: Baseline and Week 12 after completion of fixed-dose period, prior to taper down, to measure change from baseline

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 11 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical Global Impression Scale (CGI) (time frame: CGI-S and CGI-P will be administered at Baseline and Week 12 after completion of fixed-dose period, prior to taper down, to measure change. CGI-I will be administered at Week 12 after completion of fixed-dose period, prior to taper down). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05216614, which also lists 99 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
