Edmonton, AlbertaAges 18–90 - 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+ - NCT05585788Recruiting
Opioid pain device test for cancer surgery patients
This study tests a device that helps you safely use opioid (strong pain) medicine after major cancer surgery. It may help improve post-surgery pain control while tracking how people use the medicine.
New York, New YorkAges 18–99 - 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 - NCT05525767RecruitingPhase 4
Bevacizumab plus chemo before surgery for HER2-negative breast cancer
This trial studies whether adding bevacizumab (an anti-blood-vessel medicine) to chemotherapy before surgery improves treatment outcomes for people with HER2-negative breast cancer. It’s mainly for tumors that are stage II to IIIC and have not had prior cancer treatment.
Shijiazhuang, HebeiAges 18 years+ - NCT05524480Enrolling by invitation
Help Latina women get overdue breast, cervical care
This trial tests an implementation program that helps clinics better provide breast and cervical cancer screening and HPV vaccination to Latina women who are behind on recommended care. It may help you catch up on screening or start HPV vaccination and connect you to low-cost services.
Houston, TexasAges 18–74 - NCT05492682RecruitingPhase 1
First-in-human treatment for cancer using a drug injected into tumors
This Phase 1 trial tests PeptiCRAd-1, a treatment injected into a tumor, to see how safe it is and whether it can shrink cancers. It studies people whose cancer has come back or can’t be treated with standard options.
FrankfurtAges 18 years+ - NCT04722341Recruiting
Time-limited eating for people with certain breast or rectal cancers
This study tests whether eating only within a shorter daily time window can improve cancer outcomes in people with specific breast or rectal cancers. It also looks at how this affects the body (such as metabolism) and who is most likely to benefit.
Birmingham, AlabamaAges 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 - NCT05464082RecruitingPhase 2
Collect tumor samples to guide early breast cancer recurrence care
This Phase 2 study tests a “precision” approach using tumor sample testing to help predict, prevent, and treat early metastatic recurrence in triple-negative or hormone-receptor–low, HER2-negative breast cancer. If you qualify, you’ll be asked to provide tumor tissue before (or in place of) standard chemotherapy, so researchers can learn which tumor features matter most.
Salt Lake City, UtahAges 18 years+ - NCT05432856Recruiting
Track metabolic health habits during breast cancer treatment
This study follows how “metabolic health” patterns (like eating timing and daily activity) change over time during breast cancer care. It may help researchers learn which habit patterns are linked to better outcomes and comfort during chemotherapy.
