Recruiting studies in Texas
- NCT05868226RecruitingPhase 1
Early cancer drug study for adults with advanced tumors
This Phase 1 study tests early (first-in-program) cancer medicines in people whose cancer has not been adequately controlled. It helps researchers learn the safest dose and early signs of whether the treatment may work for different tumor types and treatments.
Houston, TexasAges 18 years+ - NCT05919108RecruitingPhase 2
Neratinib before surgery for HER2-mutated invasive lobular breast cancer
This Phase 2 trial tests neratinib given before surgery to treat stage I–III invasive lobular breast cancer that has a specific HER2 mutation and is hormone-receptor positive. It may help shrink the tumor and improve control of cancer before and after surgery.
Dallas, TexasAges 18 years+ - NCT06016738RecruitingPhase 3
Palazestrant vs standard therapy for advanced breast cancer
This trial compares a new oral drug, palazestrant (OP-1250), to standard hormone therapies for people with ER+/HER2- advanced breast cancer that has worsened after prior hormone therapy. It tests whether palazestrant can better control the cancer.
Dallas, TexasAges 18 years+ - NCT06072612RecruitingPhase 3
Bria-IMT plus CPI vs standard care for advanced breast cancer
This trial tests a new combination of two immunotherapy drugs (Bria-IMT and a checkpoint inhibitor) against your doctor's choice of standard treatments. It is for people with advanced breast cancer that has spread and who have already tried several prior therapies.
Dallas, TexasAges 18 years+ - NCT06395519RecruitingPhase 1/Phase 2
Study of ETX-19477 for advanced solid tumors
This trial tests an experimental drug called ETX-19477 for people with advanced solid tumors that have stopped responding to other treatments. It aims to see if the drug is safe and effective, especially for those with certain genetic changes (BRCA2 mutations).
Houston, TexasAges 18 years+ - NCT06445738Recruiting
Can some women safely skip radiation after breast cancer surgery?
This trial is for women 50 and older with early-stage, hormone-positive or HER2-positive breast cancer. It tests whether it is safe to skip radiation therapy after a lumpectomy if an MRI before surgery shows the breast tissue looks a certain way.
Houston, TexasAges 50 years+ - NCT06517212RecruitingPhase 2
Tirzepatide for weight loss in MRD-positive early breast cancer
This study tests whether the weight-loss drug tirzepatide (Mounjaro) can help prevent breast cancer from coming back in people who are overweight and have a sign of leftover cancer cells in their blood (called MRD-positive). You must have already finished at least one year of hormone therapy for early-stage breast cancer.
Dallas, TexasAges 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.
Houston, TexasAges 18 years+ - NCT06545682RecruitingPhase 1
Study of alpelisib and pembrolizumab for advanced breast cancer or melanoma
This trial tests a combination of two drugs, alpelisib and pembrolizumab, for people with advanced triple-negative breast cancer or melanoma that has spread. The goal is to see if the combination can help shrink tumors, including those that have spread to the brain.
Houston, TexasAges 18 years+ - NCT06568692RecruitingPhase 2
Study of PCS6422 with capecitabine for advanced breast cancer
This trial tests a new drug combination (PCS6422 plus capecitabine) for people with advanced or metastatic breast cancer that has not responded to other treatments. The goal is to see if adding PCS6422 can make the chemotherapy work better.
San Antonio, TexasAges 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.
Abilene, TexasAges 18 years+ - NCT06444269RecruitingPhase 2
Precision radiation before surgery for early hormone-positive breast cancer
This trial tests a focused radiation treatment before surgery for early-stage breast cancer that is hormone receptor positive and HER2 negative. The goal is to give precise radiation only to the tumor, with the hope of reducing side effects and improving outcomes.
Dallas, TexasAges 18 years+ - NCT06784193RecruitingPhase 1
Study of OP-3136 for advanced solid tumors
This trial tests a new drug, OP-3136, alone or with other drugs, for people with advanced breast cancer, prostate cancer, or lung cancer that has stopped responding to other treatments. It aims to see if OP-3136 is safe and effective.
San Antonio, TexasAges 18 years+ - NCT06897488RecruitingPhase 2
Omitting endocrine therapy and radiation in low-risk breast cancer
This trial tests whether older women with very low-risk, hormone-positive breast cancer can safely skip endocrine therapy (hormone-blocking pills) and radiation after lumpectomy. It aims to maintain quality of life while keeping cancer from coming back.
Houston, TexasAges 60 years+ - NCT06959537RecruitingPhase 1
Combination drug therapy for triple negative breast cancer
This trial tests a new combination of three drugs (cyclophosphamide, axatilimab, and retifanlimab) for people with metastatic triple negative breast cancer. The goal is to see if adding a low dose of chemotherapy can make the immunotherapy work better.
Houston, TexasAges 18 years+ - NCT06966453RecruitingPhase 1/Phase 2
Study of disitamab vedotin for HER2-positive advanced breast cancer
This study tests a new drug called disitamab vedotin for people with advanced breast cancer that has a certain amount of HER2 protein. Depending on your HER2 and hormone receptor status, you may be eligible for one of three groups, each with different prior treatment requirements.
San Antonio, TexasAges 18 years+ - NCT07214662RecruitingPhase 1
Study of GDC-0587 with or without giredestrant for advanced breast cancer
This trial tests a new drug (GDC-0587) by itself or with another drug (giredestrant) in people with a type of breast cancer that is ER-positive and HER2-negative, and has spread or cannot be removed. It aims to see if the drug is safe and works against the cancer.
San Antonio, TexasAges 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).
Dallas, TexasAges 18 years+ - NCT02926690RecruitingPhase 1
MELK inhibitor safety study for advanced breast cancer
This Phase 1 study tests how safe a drug called an MELK inhibitor is in people with advanced breast cancer that has spread or cannot be removed with surgery. If you qualify, the study is focused on side effects and includes a special group for triple-negative breast cancer.
Houston, TexasAges 18 years+ - NCT02945579Recruiting
Testing skipping breast surgery or radiation for top responders
This trial studies whether some people with early-stage breast cancer who respond extremely well to hormone/chemo/targeted treatment can safely skip breast surgery and/or radiation. It aims to reduce side effects without increasing cancer risk in carefully selected patients.
Houston, TexasAges 30 years+ - NCT05879926RecruitingPhase 3
Testing chemo after hormone therapy in premenopausal early breast cancer
This Phase 3 trial checks whether adding chemotherapy after standard hormone-blocking treatment works better for some premenopausal women with early-stage, ER-positive, HER2-negative breast cancer. It targets patients with limited lymph node spread and a lower-to-intermediate tumor “recurrence” risk score.
Amarillo, TexasAges 18–60 - 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.
Houston, TexasAges 18–55 - NCT05035836RecruitingPhase 2
Test drug after early HER2-positive breast cancer surgery
This trial tests zanidatamab, a type of targeted antibody treatment, in people with early-stage HER2-positive breast cancer to see how well it works and how safe it is. Because it’s a single-arm pilot study, everyone in the study gets the drug, and you’ll likely be asked to undergo standard surgery if appropriate.
Houston, TexasAges 18 years+ - NCT05501704RecruitingPhase 2
Testosterone-blocking therapy for male breast cancer
This Phase 2 study tests an oral treatment (called “ET”) to treat hormone-receptor–positive, HER2-negative invasive breast cancer in men. It may help shrink or control cancer without using standard cancer treatments first.

What taking part in a er+ 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.
