Barlow-style program for thinking and memory problems after breast cancer
This trial tests a structured “Barlow Protocol” program to help improve mild to moderate thinking and memory problems in people who finished breast cancer chemotherapy. It may help if your cognitive symptoms started after treatment and you’re not already in similar therapy.
CórdobaAges 18–70 - NCT05293470Recruiting
Tracking the real-world effects of Piqray in Korea
This study monitors how well and how safely Piqray works for people in Korea in routine care. You may be invited if your breast cancer matches specific genetic and receptor test results and you are starting Piqray for the first time.
Cheonan Si, Chungcheongnam-doAges 18–100 - NCT05283330RecruitingPhase 1
Tested 212Pb imaging drug for certain advanced GRPR tumors
This early-phase study tests how safe and tolerable an experimental radiation drug is for adults with certain advanced or metastatic cancers that show a target called GRPR. Doctors will also use special scans to confirm the tumor has the target so the treatment can be delivered to the right place.
Chicago, IllinoisAges 18 years+ - NCT05213962Enrolling by invitation
Radiation after nipple-sparing mastectomy with implant
This study tests local and regional radiation treatment after nipple-sparing mastectomy done with an implant. It may help reduce cancer returning in the breast/nearby tissues for people whose cancer hasn’t spread to distant sites.
Goyang-si, Gyeonggi-doAges 20 years+ - NCT05208762RecruitingPhase 1
PD-L1 antibody drug study for advanced lung and head/neck cancers
This Phase 1 trial tests a new experimental drug (PF-08046054/SGN-PDL1V) in people with advanced solid tumors that have not responded to standard treatment or can’t use it. It is designed to see how the drug works and how safe it is, with a focus on tumors that have PD-L1 seen on prior lab testing.
Birmingham, AlabamaAges 18 years+ - NCT05232916RecruitingPhase 3
Vaccine for HER2-positive breast cancer after standard treatment
This trial tests a vaccine (GLSI-100) that may help prevent the return of HER2-positive breast cancer. It is given to patients who still had cancer cells after initial treatment with trastuzumab, or who had stage III disease and achieved a complete response.
Mobile, AlabamaAges 18–100 - NCT05225428Recruiting
Video education program based on personal genetic result disclosure
This study tests a video-based education approach that shares information differently depending on someone’s genetic test results. It may help people better understand cancer-related genetic information and what it could mean for them.
Boston, MassachusettsAges 18 years+ - NCT04530890Recruiting
Testing blood tumor DNA in digestive and breast cancers
This study looks at a blood test for “circulating tumor DNA” (tiny pieces of cancer-related DNA in the blood). It may help doctors learn more about digestive, gynecologic, or breast cancers and how patients respond when treatment like chemotherapy or immunotherapy is needed.
PoitiersAges 18 years+ - NCT05183165Recruiting
Study measures copper levels in breast milk for Wilson’s disease
This study measures how much copper is present in breast milk in people with Wilson’s disease. It aims to provide safer guidance for breastfeeding during treatment, including during pregnancy.
ParisAges 18 years+ - NCT05142787Recruiting
Magnetic breast marker to guide removal of a lump
This study tests a magnetic marker system (placed in the breast or armpit area) to help surgeons find and remove a suspicious lump or lymph node. If you’re having breast/axillary lesion or node removal, this may help guide the procedure.
BottropAges 18 years+ - NCT05183126RecruitingPhase 4
Paclitaxel dose study using a 1-hour muscle-area infusion
This trial studies how paclitaxel (a chemotherapy medicine) behaves in the body when given by a specific 1-hour infusion approach. It may help refine dosing for people with cancer using measurements from scans, and it includes a medicine schedule you must match.
Ann Arbor, MichiganAges 18 years+ - NCT05160480Enrolling by invitation
Total-body PET scan using FDA-approved tracers for prostate or NET cancer
This pilot study tests a total-body PET scan with approved tracer medicines to help detect cancer spread in people with suspected metastatic prostate cancer or certain neuroendocrine tumors (NETs). You may be able to join if recent scans already suggest metastasis and you can safely complete the scan timing and positioning.
