Recruiting studies
- NCT05492682RecruitingPhase 1
First-in-human treatment for cancer using a drug injected into tumors

FrankfurtAges 18 years+ - NCT05496829Recruiting
Improving how people take breast-cancer and heart medicines
This trial tests an intervention to help improve how equitably people take their prescribed breast cancer hormone therapy and heart-related prevention medicines. It may help if you have had trouble taking these medications as directed.
New York, New YorkAges 18–99 - NCT05502224Recruiting
Program for ongoing fatigue in young cancer survivors
This study tests a multidisciplinary program to help reduce ongoing fatigue after acute cancer treatment. It is for younger adults who still feel at least moderate fatigue about a month after finishing treatment.
BrusselsAges 18–39 - NCT05512286Recruiting
Radiation experience after breast surgery with belly flap
This trial looks at how people feel (patient-reported outcomes) and how safe treatment is when radiotherapy is given after a mastectomy with a DIEP belly skin-flap reconstruction. It may help doctors understand which experiences to expect and how to improve care.
Nanning, GuangxiAges 18 years+ - NCT05522959Recruiting
Exercise rehab for breast cancer recovery
This trial tests an exercise-based rehabilitation program for people who have had early-stage breast cancer and are finishing or currently getting standard treatments like chemotherapy, surgery, radiation, or targeted drugs. It may help improve heart and breathing fitness during recovery.
Toronto, OntarioAges 18 years+ - NCT05544240RecruitingPhase 1
First-in-human immunotherapy study for advanced solid tumors
This Phase 1 trial tests SYNC-T, an immunotherapy, in people with advanced or metastatic solid cancers. It aims to find the safest dose and see whether the treatment can shrink or control tumors.
Mexico CityAges 18 years+ - NCT05549024RecruitingEarly Phase 1
PET/CT scan study for certain prostate, brain, or breast cancers
This early-phase study tests special PET/CT scans using a radioactive tracer to see cancer areas that have specific targets. It may help doctors better visualize tumors and plan next steps, using scans that you may already be familiar with (FDG) plus targeted tracers.
BeijingAges 18 years+ - NCT05556473RecruitingPhase 1
Tryptophan PET/CT scan study for different tumors
This early-phase study tests a special PET/CT scan using labeled tryptophan to help doctors see how different tumors behave. The goal is to learn whether this scan can better identify and measure cancers in the brain or elsewhere.
Detroit, MichiganAges 18 years+ - NCT05559164RecruitingPhase 2
Statins to protect the heart during HER2 breast cancer treatment
This trial tests whether a cholesterol medicine (a statin) can lower the risk of heart damage in people receiving HER2-targeted breast cancer therapy. If you qualify, you may be given a statin and followed with heart tests and blood work to watch for safety and benefit.
Elizabeth, New JerseyAges 18 years+ - NCT05590351Recruiting
Mobile app coaching for exclusive breastfeeding in Pakistan
This study tests whether a smartphone app can help pregnant mothers practice “exclusive breastfeeding” and other early child-feeding habits. If you join, you’ll receive app support during pregnancy and after birth to improve feeding and breastfeeding outcomes.
Karachi, SindhAges 18–48 - NCT05598879Recruiting
New heart-cancer visit registry for adults
This study is a “registry,” meaning it collects health information from adults who are getting a new heart (cardio) evaluation related to cancer. It helps doctors better understand heart risks and care needs for different cancer types and treatments.
Weston, FloridaAges 18 years+ - NCT05616988Recruiting
Study body-image improvement after breast cancer surgery
This study looks at how body image changes after mastectomy and breast reconstruction, and whether certain body chemistry patterns (called metabolomics) are linked to that change. It may help researchers understand what supports better body-image recovery after breast cancer.
Rome, RomeAges 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+ - NCT05621837Recruiting
Biomarker study to guide treatment for several advanced cancers
This study measures how strongly your immune system is being suppressed and uses that information to help personalize cancer treatment. It mainly looks at people with certain advanced cancers and needs tumor tissue and follow-up to check possible immune-related markers.
MilanAges 18–90 - NCT05645510Recruiting
Study for people on long-term cancer targeted medicines
This study looks at people who are already taking long-term targeted cancer medicines. It may help researchers understand how these treatments work over time and whether there are ways to improve care.
Edmonton, AlbertaAges 18–90 - NCT05649072Recruiting
Mobile mammogram screening study for women with family cancer risk
This study looks at how well mobile mammogram units and video/phone genetics counseling (“telegenetics”) can help women who may have inherited cancer risk. If you’re scheduled for a mammogram through the Project VALET mobile units, this may be an easy option to learn about and address your risk.
Houston, TexasAges 18 years+ - NCT05684367Recruiting
Exercise program to rebuild stamina and energy after breast cancer
This study tests whether a structured exercise program can help older adults with breast cancer regain stamina and reduce fatigue. It focuses on people who are still dealing with moderate fatigue after finishing certain breast cancer treatments.
Gainesville, FloridaAges 60–105 - NCT05689619Recruiting
Silibinin after one brain metastasis surgery for lung or breast cancer
This trial studies silibinin, a natural substance, to help prevent brain metastasis from coming back after surgery. It is for people with lung (NSCLC) or breast cancer who have exactly one small brain metastasis that is fully removed and has a specific lab marker in the brain tissue.
GenovaAges 18–70 - NCT05693766RecruitingPhase 2
Gene test guides treatment for hormone-positive breast cancer
This trial studies whether a gene-signature test can help guide treatment choices for people with hormone receptor–positive (ER and/or PR) breast cancer that has spread or can’t be fully removed. It may help find the best therapy approach after prior hormone therapy and targeted cancer medicine.
Birmingham, AlabamaAges 18 years+ - NCT05694559Recruiting
Genetic risk screening and counseling for Black adults
This study connects Black adults to genetic counseling and genetic testing to learn whether they may have an inherited cancer risk. It uses a simple risk screening tool, including visits by phone or video, to guide next steps.
Houston, TexasAges 18 years+ - NCT05695313RecruitingPhase 2
Prevent nerve damage during weekly paclitaxel breast cancer treatment
This Phase 2 study tests whether a daily tablet (Onlife) can help prevent nerve side effects (“neurotoxicity”) caused by weekly paclitaxel given for breast cancer. You’d be randomly assigned to the tablet or a placebo, and you would be closely followed with questionnaires and clinic visits.
DijonAges 1.5 years+ - NCT05704166RecruitingPhase 2
Pirfenidone to prevent lung injury after breast radiation
This trial tests whether pirfenidone, a medication, can prevent acute lung injury caused by radiation therapy in people with breast cancer. You may be randomly assigned to pirfenidone or a placebo (inactive pill) to see which better protects the lungs during and after radiation.
Fuzhou, FujianAges 18–75 - NCT05721976Recruiting
Grandmother–daughter lifestyle program for certain cancer survivors
This pilot study tests a supportive program for grandmothers who finished breast, endometrial, or ovarian cancer treatment and their adult daughters. It aims to encourage healthier habits, including physical activity, using phone-based support and Spanish/English materials.

- 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.
