Recruiting studies
- NCT06223022Enrolling by invitation

Study of CTX-8371 for advanced cancers no longer helped by standard therapy
This trial tests a new drug called CTX-8371 for people with advanced cancers (melanoma, head and neck, lung, triple-negative breast, or Hodgkin lymphoma) that have stopped responding to standard treatments, especially immunotherapy. It is a first-in-human study, meaning doctors are learning if the drug is safe and how well it works.
Margate, FloridaAges 18 years+ - NCT06139107RecruitingPhase 1
Radiation and abemaciclib plus letrozole before breast cancer surgery
This trial combines a short course of radiation before surgery with two oral medications (abemaciclib and letrozole) to treat early-stage, hormone-sensitive breast cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
Belleville, New JerseyAges 60 years+ - NCT06134375RecruitingPhase 1/Phase 2
TM plus capecitabine for triple-negative breast cancer
This trial tests a drug called tetrathiomolybdate (TM) combined with capecitabine for people with triple-negative breast cancer who still have cancer cells after standard chemotherapy and surgery. The goal is to see if this combination can help prevent the cancer from coming back.
Indianapolis, IndianaAges 18–80 - NCT06107686RecruitingPhase 2
YL202 for advanced solid tumors
This trial tests a new drug called YL202 for people with advanced solid tumors (cancers that have spread or cannot be removed). It aims to see if the drug can shrink tumors or slow cancer growth. You may be able to join if you have certain types of cancer, have not had a previous HER3 treatment, and can provide a tumor sample.
Hefei, AnhuiAges 18–75 - NCT06107933Recruiting
Study on how microplastics affect babies' development
This study looks at how tiny plastic particles in breast milk might affect a baby's growth and development. You may be able to join if you are a new mom who is exclusively breastfeeding without any formula.
Baltimore, MarylandAges 18 years+ - NCT06123286RecruitingEarly Phase 1
Tart cherry and omega-3s for joint pain from hormone therapy
This study tests whether taking tart cherry and omega-3 supplements can help reduce joint pain and stiffness caused by aromatase inhibitors (a common breast cancer treatment). If you have bothersome joint pain while on this hormone therapy, you may be able to join.
Los Angeles, CaliforniaAges 18 years+ - NCT05620329Recruiting
Pleural fluid registry for drainage in adults
This registry collects information from adults who have fluid around the lungs (pleural effusion) and need clinically indicated drainage because of infection or cancer. It helps researchers better understand these conditions and improve future care.
Chapel Hill, North CarolinaAges 18 years+ - NCT06097156Recruiting
Automated blood test for breast cancer monitoring
This trial tests an automated device that prepares blood samples to detect cancer-related changes. It aims to improve how doctors monitor breast cancer that has spread, without needing a tissue biopsy every time.
MilanAges 18 years+ - NCT06104371Recruiting
Magnetic markers to find lymph nodes before chemo for breast cancer
This trial tests a new method using magnetic markers (Magtrace and Magseed) to find lymph nodes before chemotherapy. It may help doctors better target the lymph nodes that need to be removed during breast cancer surgery.
GothenburgAges 18–85 - NCT06085313Recruiting
Web-based program for cancer pain in Asian women
This trial tests a web-based program to help women of Chinese, Korean, or Japanese heritage manage breast cancer pain and depressive symptoms. If you've had breast cancer, have had pain in the past week, and feel some depression, this program could help you cope better.
Austin, TexasAges 18 years+ - NCT06103669Recruiting
Local treatment for limited cancer spread
This trial tests whether using local treatments (like targeted radiation or ablation) on a few new spots of cancer can help people whose cancer is otherwise stable on their current treatment. It enrolls people with various solid tumors, such as breast, gynecologic, head & neck, sarcoma, or other types.

Testing sacituzumab govitecan with or without pembrolizumab for early triple-negative breast cancer
This trial tests a two-drug combination (sacituzumab govitecan and pembrolizumab) versus sacituzumab govitecan alone before surgery for low-risk, triple-negative breast cancer that hasn't spread. The goal is to see which approach works better at shrinking tumors.

Study of VLS-1488 for advanced cancers
This early-phase study tests VLS-1488, a new cancer medicine, in people with advanced cancers that have limited treatment options. It may help by finding a safe dose and whether it can shrink or control tumors.
Los Angeles, CaliforniaAges 18 years+ - NCT05978128Recruiting
Use advocates to boost lung cancer screening
This trial tests whether trained advocates and supporters can help people who are eligible for lung cancer screening actually get screened. It may help you (and others) by making screening easier to plan and complete.

- Are there clinical trials for breast?
- Yes. Clin2 currently lists 2,625 recruiting breast studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a breast trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a breast trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
