Testing azirkitug for lung, head/neck, and other solid cancers
This Phase 1 study tests how a new medicine (azirkitug) behaves in the body and how safe it is, given by IV infusion alone or with other cancer drugs. It may help people with several advanced solid tumor cancers, especially after standard treatments have stopped working.
Duarte, CaliforniaAges 18 years+ - NCT05059444Recruiting
Blood test to catch cancer early after treatment
This study looks for signs of cancer left in the body after treatment using a simple blood test (called a liquid biopsy). It aims to see if the test can catch cancer that might come back earlier than regular scans.
Birmingham, AlabamaAges 18 years+ - NCT05056818Recruiting
Compare two types of breast X-ray images for reading accuracy
This study compares a computer-generated (“synthetic”) mammogram to the standard full-field digital mammogram to see which gives better image-reading results. It may help improve how breast images are interpreted in everyday practice.
Houston, TexasAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
Gilbert, ArizonaAges 18 years+ - NCT04937309Recruiting
Vagus nerve stimulation for nausea from chemo
This trial tests a non-invasive device that stimulates a nerve in your ear to help prevent nausea caused by chemotherapy. It is for people with breast cancer who are about to start a specific type of chemo (anthracycline and cyclophosphamide).
BloisAges 18 years+ - NCT04986579RecruitingPhase 2
Scalp cooling to reduce hair loss during breast cancer chemotherapy
This Phase 2 trial tests whether using a scalp-cooling device during chemotherapy can help prevent or lessen hair loss in people with metastatic invasive breast cancer. You would need to be starting a specific chemotherapy plan and be willing to begin scalp cooling with your first treatment.
Boston, MassachusettsAges 18 years+ - NCT05000294RecruitingPhase 1/Phase 2
Atezolizumab plus tivozanib for hard-to-treat “cold” cancers
This early-stage study tests whether combining atezolizumab and tivozanib can shrink advanced, hard-to-treat cancers that do not strongly activate the immune system (“immunologically cold”). It is for people whose cancer has already been treated or has no good standard options.
Gainesville, FloridaAges 18–99 - NCT04992650Enrolling by invitation
Ultrasound imaging during breast reconstruction after mastectomy and radiation
This study uses ultrasound pictures to better understand blood flow in breast reconstruction sites after a mastectomy, when you also need radiation therapy. It may help improve how clinicians monitor and manage healing and treatment effects in this situation.
Rochester, MinnesotaAges 18 years+ - NCT04994067Recruiting
Registering radiation given during breast-conserving surgery
This study records details about radiation delivered while your surgery is happening for certain early breast cancers or pre-cancers. It may help doctors better understand who benefits most from this “intra-operative” radiation approach.
The Bronx, New YorkAges 18 years+ - NCT04895709RecruitingPhase 1/Phase 2
Testing a new cancer drug for advanced solid tumors
This early-phase trial tests how well a new drug (BMS-986340) works alone and combined with other treatments in people with advanced solid tumors that have progressed despite standard care. It also studies tumor samples to look for biomarkers that may predict who benefits.
Clovis, CaliforniaAges 18 years+ - NCT04916990Recruiting
Care program for rural adults with several lung and head cancers
This study looks at how to improve care for adults with certain cancers who live in rural areas and may face access problems. It mainly focuses on people receiving cancer treatment at specific Colorado-area hospitals, and who are uninsured or underinsured.
Aurora, ColoradoAges 18–99 - NCT04751435Recruiting
Genetic testing education for cancer patients of diverse backgrounds
This study tests new educational materials about genetic testing for cancer patients. It aims to find the best ways to explain genetic testing to people from different backgrounds, especially Black, Latino, and non-Latino non-Black communities.
Brooklyn, New YorkAges 18 years+ - NCT04606446RecruitingPhase 2
Study drug for ER-positive, HER2-negative cancers after treatment
This Phase 2 study tests a new Pfizer medicine (PF-07248144) for certain advanced or metastatic breast, prostate, or lung cancers that have not responded to standard treatment or no standard options exist. You may qualify if you have a specific tumor type and a limited number of prior cancer treatments, and if your body functions (blood, liver, kidneys) and heart rhythm meet safety limits.
Scottsdale, ArizonaAges 18 years+ - NCT04641247RecruitingPhase 2
Long-term niraparib follow-up for people already benefiting
This study looks at continuing niraparib for a longer time in people who already finished an earlier niraparib trial and are still benefiting. It may help understand how safe and useful long-term treatment is for you.
Tucson, ArizonaAges 18 years+ - NCT04654208Recruiting
Study people who took palbociclib prescriptions
This study uses prescription records to learn about real-world use of palbociclib (a cancer medicine). You may be included if you’re an adult and have filled at least one palbociclib prescription.
SollentunaAges 18 years+ - NCT04614194RecruitingPhase 2
Blood and tumor markers to test response to abemaciclib
This trial studies how the immune system and other body signals in blood and tumor tissue relate to how well abemaciclib works before breast cancer surgery. The goal is to learn who benefits most from this medicine and why.
