Where Chicago trials actually run

We sampled recruiting Chicago studies on ClinicalTrials.gov in July 2026. The sites running the most trials:

Research siteTrials sampled
Northwestern University102
University of Chicago (incl. Comprehensive Cancer Center)91
Rush University Medical Center30
Lurie Children’s Hospital25

Chicago is unusual for having several large academic centers competing for participants: Northwestern in Streeterville, University of Chicago in Hyde Park, Rush on the Near West Side, and Lurie for pediatric studies. If one turns you down, another may have a similar trial.

Clinical Trials For Disease Areas in Chicago 

Research studies in Chicago, IL cover a broad spectrum of transitional science. They range from pediatric care, neurological conditions, and respiratory health to a collection of genetic and other biomarkers in medicine. 

A major focus in clinical trials is finding new treatments and diagnostic tools that provide meaningful clinical advantages. 

Some studies assess diseases like sickle cell disease and diabetic foot infections. Whereas others evaluate clinical conditions that could be relevant to patients across various diagnoses, such as cardiopulmonary resuscitation (CPR) quality and pain control. 

For example, the University of Chicago Medical Center has enrolled more than 100,000 patients in clinical trials since 1997. They’ve enrolled an extra 20,000 patients at other healthcare facilities across the nation for multicenter studies. 

In fact, UChicago Medicine has the biggest number of clinical trials in the region. In the past year, they’ve recruited over 1,000 patients for cancer medical research. 

Because of the wide range of clinical trials in Chicago, there is always a need for more volunteers. Our platform connects you with leading researchers and facilities near you. Join us as we make a lasting impact on healthcare. Sign up now!

The most successful treatments we have today for diseases like asthma, cancer, high blood pressure, and heart problems came from what we learned from clinical trials. This is why patients can enjoy a better quality of life and longer lifespan. 

Paid research studies in Chicago are here to provide a monetary benefit for those willing to participate. Clinical trials often require a lot of time and commitment from participants. You would need to get tested all the time, visit the clinic regularly, and make lifestyle changes. 

These trials also come with risks. Paid clinical trials in Chicago can motivate patients to participate, especially if they can’t afford treatment. Sponsors can cover expenses like parking fees, taking time off work, and transportation. 

The compensation for Chicago paid studies reduces the financial burden and makes new treatments more accessible for people. It also reduces the dropout rates and maintains a consistent pool of participants throughout the trial.

Medical Discoveries and Innovation in Chicago

Prediction can improve healthcare.

The University of Chicago Medicine is working with Google to study how machine learning (ML) can boost patient care. Scientists are working on creating predictive models with ML. These models could help prevent expensive complications and unexpected hospital readmissions. 

Over the last year, Google scientists have demonstrated how ML helps healthcare professionals detect breast cancer and avoid preventable vision loss. They’ve also converted research findings into practical medical tools and delivered alerts to doctors whose patients suffered from serious health issues. 

Researchers in the Department of Medicine in Chicago secured a record-breaking $169 million in funding. They also effectively applied their fundamental research in real-world clinical settings, leading to significant breakthroughs. They published thousands of notable papers featured in high-profile journals. They conducted over 1,600 clinical research studies.

Chicago Paid Clinical Trial FAQs

  • How much do paid clinical trials pay here?

    Most outpatient studies pay $50–$100 per completed visit, plus travel reimbursement. Residential Phase 1 studies pay considerably more. The exact amount appears in the consent form before you enroll.

  • Where in Chicago are most trials located?

    Northwestern’s campus in Streeterville and the University of Chicago in Hyde Park hold the largest shares, with Rush on the Near West Side and Lurie Children’s downtown. Private research sites also operate in the suburbs, including Skokie, Oak Brook, and Naperville.

  • Can I apply to studies at more than one Chicago hospital?

    Yes, though you can only enroll in one interventional drug study at a time. Applying to several sites improves your odds of finding a study you qualify for, since eligibility criteria differ between protocols even for the same condition.
