Recruiting studies in Illinois
- NCT06099769RecruitingPhase 2
Testing enzalutamide with or without mifepristone for AR-positive breast cancer
This trial tests if adding the drug mifepristone to the standard antiandrogen enzalutamide works better than enzalutamide alone or chemotherapy for people with a specific type of breast cancer that has androgen receptors. It aims to find a new targeted treatment option for triple-negative or ER-low breast cancer.
Chicago, IllinoisAges 18 years+ - NCT06533826RecruitingPhase 2
Testing two antibody drugs for HER2-low breast cancer
This trial tests two antibody-drug conjugates (Enhertu and Datroway) for breast cancer that is HER2-low or HER2-0. It aims to find the best treatment sequence for people whose cancer has stopped responding to prior therapy.
Chicago, IllinoisAges 18 years+ - NCT06492616RecruitingPhase 3
Elacestrant vs standard hormone therapy for high-risk early breast cancer
This trial tests a new hormone therapy pill (elacestrant) against standard hormone therapy for people with a common type of early breast cancer (ER+, HER2-) that has a higher chance of returning. You may qualify if you've already been on hormone therapy for 2 to 5 years and want to see if a different pill works better.
Arlington Heights, IllinoisAges 18 years+ - NCT07214532Recruiting
Guiding CDK4/6 inhibitor use by a blood test in breast cancer
This trial is for women and men with early-stage, hormone-positive, HER2-negative breast cancer. It uses a blood test (Signatera) to detect tiny amounts of cancer DNA and only starts a CDK4/6 inhibitor (ribociclib or abemaciclib) if the test shows cancer DNA is present.
Chicago, IllinoisAges 18 years+ - NCT06062498RecruitingPhase 2
Elacestrant alone or with a CDK4/6 inhibitor for advanced breast cancer
This trial compares a new hormone therapy (elacestrant) to the same therapy combined with a CDK4/6 inhibitor (palbociclib, abemaciclib, or ribociclib) for people with a specific type of advanced breast cancer (ER-positive, HER2-negative) that has a mutation in the ESR1 gene. It aims to see if the combination works better than the single drug.
Chicago, IllinoisAges 18 years+ - NCT01042379RecruitingPhase 2
Adaptive drug trial for newly diagnosed breast cancer
This study tests personalized, changing treatment plans (given before surgery) to find better options for your specific breast tumor. You may be asked for extra breast-tissue testing to help match you with the most suitable study drug(s).
Maywood, IllinoisAges 18 years+ - NCT01766297RecruitingPhase 2
Proton radiation after lumpectomy for early breast cancer
This trial studies a type of radiation made with protons to treat only part of the breast after surgery (lumpectomy) for early-stage breast cancer. It may help control the cancer while aiming to reduce radiation to surrounding tissues.
Warrenville, IllinoisAges 50 years+ - NCT07310420RecruitingPhase 1
Zoladex injection for ovarian suppression in advanced breast cancer
This trial tests a single injection of Zoladex (goserelin) to see how well it suppresses ovarian function in premenopausal women with HR+, HER2- advanced breast cancer. It may be an option if you are still having periods and your cancer has spread or cannot be removed by surgery.
Evanston, IllinoisAges 18–55 - NCT04427293RecruitingPhase 1
Testing lenvatinib and pembrolizumab before breast cancer surgery
This early-phase trial tests whether lenvatinib plus pembrolizumab given before surgery can help treat early-stage triple-negative breast cancer. If you qualify, you would receive study medicines before your planned operation to remove the tumor and nearby lymph nodes.
Chicago, IllinoisAges 18 years+ - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer
This Phase 3 trial studies whether “less intense” radiation can work as well as standard radiation for certain early-stage hormone receptor–positive, HER2-negative breast cancers that have a low Oncotype DX score. It may help reduce treatment burden while keeping cancer control strong.
Crystal Lake, IllinoisAges 50–70 - NCT03990896RecruitingPhase 2
Talazoparib for metastatic breast cancer with BRCA body DNA changes
This Phase 2 trial tests talazoparib, a targeted cancer medicine, in people with metastatic breast cancer that has a harmful BRCA1 or BRCA2 mutation found in tumor DNA circulating in the blood. If you qualify, the goal is to see how well this treatment works when the mutation is detected this specific way.
Chicago, IllinoisAges 18 years+ - NCT06184750RecruitingPhase 2
Finding the best tamoxifen dose to lower breast cancer risk
This trial tests different doses of tamoxifen to find the best one for lowering breast cancer risk in premenopausal women. It aims to see if a lower dose works as well as the standard dose with fewer side effects.
Chicago, IllinoisAges 18–55 - NCT07174336RecruitingPhase 3
Testing Tersolisib with other treatments for advanced breast cancer
This trial tests a new study drug called Tersolisib combined with other anti-cancer treatments for people with advanced breast cancer that has a specific gene change (PIK3CA). The goal is to see if the combination can help shrink or slow the cancer.

What taking part in a er positive breast cancer study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
