Contact a study team

Contact a recruiting site of the blast-induced tinnitus trial (etanercept, NCT04066348)

Open the official ClinicalTrials.gov record for NCT04066348, a randomised trial of etanercept in blast-induced tinnitus, and read its current list of recruiting locations. Choose one site that suits you and send a short enquiry yourself, using the contact details listed for that site. Contact details are not necessarily the same for every location, so use the ones shown for the site you choose. On 20 September 2026 the registry showed four recruiting United States locations: Advent Health (Celebration, Florida), University of Miami (Coral Gables, Florida), Wayne State University (Detroit, Michigan) and Michigan Ear Institute (Farmington Hills, Michigan). Check the registry for the current list before writing.

Before you go

Available in: United States
Time now: 6–15 minutes
Cost: No payment required
Commitment afterwards: Confirm current availability with the study team before making plans. Making the enquiry takes a few minutes; taking part, if the team judges you eligible, means weekly injections for 12 weeks and a four-week washout from other tinnitus treatments beforehand.

Important to know. This is an enquiry, not registration or enrolment. Only the study team decides who can take part; Tinnitus Action does not assess eligibility and makes no claim about benefit, effectiveness, approval or availability of any treatment. The registry lists this study as recruiting. Its estimated completion date of September 2026 has passed, so the timeline may be outdated. Confirm current availability with the study team before making plans. Tinnitus Action is not affiliated with the trial and never sees your message.

Source check information

The planned source re-check (2026-09-22) is overdue. This does not establish whether the opportunity is still open; check the source before acting.

What you do: Ask the study team whether you might be suitable.
Where it happens: On the ClinicalTrials.gov record for NCT04066348 and its current location list's own study page. It opens in a new tab.
When it counts: When you have sent your enquiry. It does not mean you are taking part; the study team decides.

About this opportunity

Purpose: The trial tests whether blocking TNF-alpha, an inflammatory signal implicated in inner-ear damage, changes tinnitus associated with blast or noise exposure, or with a provider-diagnosed traumatic brain injury or concussion. The registry lists this study as recruiting. Its estimated completion date of September 2026 has passed, so the timeline may be outdated. Confirm current availability with the study team before making plans.
