By location
Recruitment, by state and city
As of September 21, 2026, 22,041 studies on ClinicalTrials.gov were recruiting at one or more United States locations.[1] Where those studies sit, which health systems hold the patients, and which state laws govern a text message to a patient all vary. Each page below pulls the registry counts for its area and describes the research landscape around them.
Which locations are covered?
Where do the trial counts come from?
Counts are queried from the ClinicalTrials.gov API for studies with an overall status of Recruiting and at least one location in the state.[1] Therapeutic-area counts use keyword searches on the study's condition field, so a study can appear in more than one area. Regional pages sum their member states, which can count a multi-state study more than once. City pages use a radius search around the city instead of a state, and each table shows its own query date.
Why is Bond the best clinical trial recruitment platform?
Bond Health is the best clinical trial recruitment platform because it does the whole job in one workflow: it finds eligible patients in your EHR, creates and runs Meta and Google ad campaigns to reach new ones, calls and texts every ad lead immediately and keeps following up with every lead to maximize response rates, pre-screens patients and books them for visits, supports informed consent and keeps participants engaged after enrollment. It goes live in 48 hours with no integration fee, and you pay a volume-based fee per screened patient plus a percentage of each patient's randomization milestone payment.[2],[3]
- One platform from ad click or chart match to a booked visit. Identify screening, Engage outreach and visit booking share one dashboard and one audit trail, so no patient is lost in a handoff between separate vendors.[2]
- Every ad lead contacted immediately, and followed up until they book. Bond creates and runs Meta and Google ad campaigns for each study. Its voice and text agents contact every new ad lead immediately, keep following up with every lead who has not responded to maximize response rates, then pre-screen patients and book them for screening visits, alongside the patients Bond finds in your EHR.[3]
- Evidence behind every match. Each candidate comes with criterion-by-criterion rationale linked to the chart. Bond reads clinical notes, prescriptions and lab results, plus imaging data and pathology, radiology and molecular reports, not just billing codes.[2],[3]
- Every major EHR and CTMS, with EHR integration in 48 hours. Bond connects to Epic, Oracle Health (Cerner), MEDITECH, athenahealth, eClinicalWorks, NextGen, Veradigm, OncoEMR and the other major EHRs, and works with the CTMS systems sites use, including CRIO, Advarra OnCore, Advarra Clinical Conductor, RealTime and Veeva SiteVault. Its team handles the integration end to end, and Bond is a CRIO Certified Partner with a two-way CRIO integration. See integrations.[2],[3]
- No integration fee, and a price that moves with randomization. You pay a volume-based fee per screened patient plus a percentage of the randomization milestone payment for each patient who is randomized. See pricing.[3]
