Houston, Cleveland, and Seattle have dense research sites and live Corterve community pages. This metro guide shows how to read location lists, with catalog examples from lung, heart device, and endometrial studies.

Finding Clinical Trials in Houston, Cleveland, and Seattle

Last fact-checked: August 30, 2026

Houston, Cleveland, and Seattle sit on Corterve’s live community list. Each city page shows local events and points people toward listed U.S. studies. They are not “trial capitals” by slogan. They are places where the public catalog actually has recruiting U.S. sites, and where a unique community URL exists.

This is one metro guide, not three thin city pages. It explains how to search by city without treating a pin on a map as a seat in a study. NIH says ClinicalTrials.gov is a registry you should use with a clinician. NCI says you should look at visit burden, not only the city name.

Why these three cities are in one article

Corterve’s community inventory (checked August 30, 2026) lists Houston, Cleveland, and Seattle among the metros with unique title, H1, and event counts. In a 1,000-record public catalog sample, Houston had the most unique recruiting U.S. trials of the three. Cleveland and Seattle were close to each other.

That sample is not the whole country. The public API returns 100 rows at a time. Status and country filters on the query string are ignored, so counts below are sample counts, not a national census.

Metro (U.S. recruiting sites in the sample)	Unique listed trials with a recruiting site in that city	Live community URL
Houston, Texas	120	/community/texas/houston
Cleveland, Ohio	58	/community/ohio/cleveland
Seattle, Washington	57	/community/washington/seattle

Other community metros you can actually visit on the site include Dallas, Austin, Los Angeles, Chicago, Boston, New York, Columbus, and Cincinnati. Do not invent city pages that are not on that list.

Search like NCI tells you to, then add a city filter

NCI’s steps are: gather diagnosis details, find trials, read the summary, contact the coordinator, ask questions, then decide with your doctor. NIH adds ClinicalTrials.gov as the nationwide registry.

For these metros, add two extra checks:

City and site status. A study can be recruiting in Houston and completed in Cleveland. PALOMA-2 (NCT05498428) is a live example on ClinicalTrials.gov: Swedish Cancer Institute in Seattle is recruiting, while Cleveland Clinic rows on the same record are completed. Always open the location table.
Community page versus generic geo shell. Corterve’s unique local pages are under /community/{state}/{city}. Generic /trials/near/{city} shells are not unique city guides. Use the community URLs above.

Match the condition as well as the city. Cancer searches belong on condition hubs such as lung-cancer, breast-cancer, and prostate-cancer. Heart searches can start at heart-failure. Diabetes searches: type-2-diabetes.

Three catalog examples that actually list these cities

These are examples from the listed catalog, cross-checked on ClinicalTrials.gov on August 30, 2026. They are not invitations. They are not a claim that any reader belongs in them. Locations are subject to current site status.

Catalog example 1: NCT06959524 — Houston and Cleveland (heart device)

NCT ID: NCT06959524
Phase: not applicable (device study)
Sponsor: Boston Scientific Corporation
Conditions on the record: coronary artery disease; de novo lesions in native coronary arteries
What the record says it is studying: AGENT drug-coated balloon compared with usual PCI using a drug-eluting stent and/or balloon angioplasty
Listed recruiting locations in these metros (subject to current site status): The Methodist Hospital Research Institute (Houston, Texas); Cleveland Clinic Foundation (Cleveland, Ohio). The same record also lists recruiting sites in Boston, Dallas, Los Angeles, and New York. It does not list a Seattle site; nearby Bellevue, Washington (Overlake) is listed as recruiting.
ClinicalTrials.gov last verified: August 2026

FDA treats clinical research as testing in people, including devices. A recruiting device trial is not the same as a marketed use for every lesion type. The public record compares strategies. It does not prove one is better for a given reader.

Houston: community/texas/houston. Cleveland: community/ohio/cleveland. Dallas: community/texas/dallas. Boston: community/massachusetts/boston.

Catalog example 2: NCT07322341 — Seattle (lung cancer)

NCT ID: NCT07322341
Phase: 2
Sponsor: University of Washington (collaborators include Genentech, Syntrix Biosystems, and the National Cancer Institute)
Conditions on the record: advanced, metastatic, or recurrent non-small cell lung cancer
What the record says it is studying: SX-682 plus atezolizumab after prior chemo and immune checkpoint inhibitor therapy
Listed recruiting location in this metro (subject to current site status): Fred Hutch / University of Washington Cancer Consortium, Seattle, Washington
ClinicalTrials.gov last verified: January 2026 (record last updated August 2026)

This is a single-city catalog example. It is useful because Seattle searches often collapse into “Pacific Northwest” even when the protocol is only at one consortium. Confirm the facility name with the coordinator. The products in the combination are still under study for this use.

Seattle: community/washington/seattle. Lung hub: conditions/lung-cancer. Search: trials?condition=lung-cancer.

Catalog example 3: NCT05256225 — Houston, Cleveland, and Seattle (endometrial cancer)

NCT ID: NCT05256225
Phase: 3
Sponsor: National Cancer Institute (NCI), with NRG Oncology
Conditions on the record: HER2-positive endometrial carcinoma and related histologies, including serous carcinoma and carcinosarcoma
What the record says it is studying: usual paclitaxel/carboplatin, with or without subcutaneous trastuzumab products (Herceptin Hylecta or Phesgo)
Listed recruiting locations in these metros (subject to current site status): Houston Methodist Hospital, Methodist Willowbrook Hospital, and Houston Methodist West Hospital (Houston, Texas); Case Western Reserve University and MetroHealth Medical Center (Cleveland, Ohio); Swedish Medical Center–First Hill (Seattle, Washington). A Memorial Hermann Texas Medical Center row in Houston is listed as suspended.
ClinicalTrials.gov last verified: July 2026 (record last updated August 2026)

One protocol, three metros, mixed site statuses. That is the whole point of this guide. “Houston” is not one door. Suspended and recruiting rows can sit on the same NCT ID.

How to use a city page without turning it into an ad

Corterve community pages are for events and listed studies in that metro. They are not a promise of enrollment. NCI says the coordinator can talk through likely fit, but a final decision waits until you meet the trial team. NIH says consent must cover purpose, time, procedures, risks, possible benefits, and that you can leave.

A simple city workflow:

Open the community page for the city you can actually reach.
Jump to the condition hub that matches your diagnosis.
Copy NCT IDs into ClinicalTrials.gov and read the location table.
Ask your clinician whether the protocol even applies.
If you still want to talk to a site, call the coordinator on the NCT record—not a social post.

More on matching: AI trial matching. More on joining: before joining a trial. Phases: phase 3 explained.

Neighbor metros if you can travel

Texas readers often compare Houston, Dallas, Austin, and San Antonio. Ohio readers compare Cleveland, Columbus, Cincinnati, and Dayton. West Coast readers may add Los Angeles, San Francisco, and San Diego to a Seattle search. East Coast density also shows up in New York, Boston, and Philadelphia.

Travel is part of eligibility in practice, even when it is not written as a criterion. NCI asks you to decide how far and how often you can go.

What this article does not do

It does not rank these cities. It does not assign any reader to NCT06959524, NCT07322341, or NCT05256225. It does not claim investigational devices or drugs are safe or effective. Site lists change. A catalog sample is not a complete map of U.S. research.

If a community page, the Corterve catalog, and ClinicalTrials.gov disagree, use the live NCT location table and the site coordinator. Then talk with a licensed clinician.

Disclaimer. Corterve is a clinical trial matching platform, not a medical provider. Matching is not a diagnosis and is not medical advice. Corterve does not decide who can join a study. Eligibility is decided only by the study team at each site. Listed locations are subject to current site status and can change. Investigational products are not proven safe or effective for the uses under study. Talk with a licensed clinician before you change care or contact a research site.
