About this study

Official title: Phase IV Study Evaluating The Safety And Clinical Efficacy Of Elderberry Extract In Patients With Influenza: A Randomized, Double-Blind Placebo-Controlled Trial

This research is being done to determine if an extract of cooked elderberries will help decrease the duration and severity of influenza symptoms in patients with confirmed influenza. Involvement in this study requires an initial patient screening at the time of their Emergency Department visit in order to confirm eligibility for the study. Once patients have been consented and enrolled as a participant, they will be randomized to take by mouth either Elderberry Extract or a placebo (a similar appearing and tasting liquid without elderberry) for a duration of 5 days. Study information regarding medication adherence, body temperature, symptoms, severity of symptoms, and any possible side effects will be collected from daily phone surveys conducted by the study coordinator. Participation in the study will end after at least 5 days once the patient has not had a temperature above 100°F and has had no influenza symptoms for at least 24 hours, or after 21 days in the study, whichever occurs first.

Study groups in NCT03410862
Study groupRoleWhat they receive
Elderberry ExtractExperimentalPatients will be supplied a liquid Elderberry Extract used to treat their confirmed human influenza. The dosage of the assigned medication will be 15 ml, or 1 tablespoon. Participants aged 5-12 will be asked to take the medication 2 times per day (morning/night) for a period of 5 days. Participants aged 13 and above will be asked to take the medication 4 times per day (morning/noon/afternoon/night) for a period of 5 days.
Receives: Drug: Elderberry Extract
PlaceboPlacebo comparatorPatients will be supplied a liquid Placebo medication (similar in appearance and taste of Elderberry Extract) used to treat their confirmed human influenza. The dosage of the assigned medication will be 15 ml, or 1 tablespoon. Participants aged 5-12 will be asked to take the medication 2 times per day (morning/night) for a period of 5 days. Participants aged 13 and above will be asked to take the medication 4 times per day (morning/noon/afternoon/night) for a period of 5 days.

What is being measured

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

  1. Number of Days Until Alleviation of Flu Symptoms Post Treatment

    Symptoms will be recorded using the scoring system described in a meta-analysis of "all published and unpublished Roche-sponsored randomized placebo-controlled, double-blind trials of oseltamivir treatment in adult influenza" (BMJ 4/9/2014). "The primary outcome will be time to alleviation of all symptoms. Seven influenza symptoms (nasal congestion, sore throat, cough, aches and pains, fatigue, headaches, and chills or sweats)" will be graded by severity as "none/absent" (0), "mild" (1), "moderate" (2), or "severe" (3). Alleviation will be defined to arise when all symptoms scored as absent or mild, and remain so for at least 21.5 hours."

    Measured: every 24 hours post study drug administration for minimum of 5 days up to 21 days

  2. Number of Days Until Complete Resolution of All Flu Symptoms for 24 Hours

    Participants were called daily and asked to report on the severity of their symptoms present. Symptoms graded according to severity score (NONE/ABSENT=0 MILD=1 MODERATE=2 SEVERE=3).

    Measured: every 24 hours post study drug administration for minimum of 5 days up to 21 days

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 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: finished, as of the sponsor's last update on 19 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Jan 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Days Until Alleviation of Flu Symptoms Post Treatment (time frame: every 24 hours post study drug administration for minimum of 5 days up to 21 days). The study lists 2 primary outcomes in all. 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 NCT03410862, which also lists 1 linked publication.

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.

How often is this information updated?
