Recruiting studies
- NCT03551951Recruiting
Testing cancer cells and DNA in blood, urine, and bone marrow
This study looks for cancer-related cells and DNA in samples like blood, urine, and (for some) bone marrow. The goal is to see whether these tests can help detect or track solid cancers with minimal added procedures.
Columbia, MissouriAges 18 years+ - NCT03958240Recruiting
Study how cancers trigger the immune system
This study looks at what makes some cancers more “noticeable” to the immune system. It may help researchers design better future immunotherapy by collecting information (often including blood samples) from people with different cancers.
ToulouseAges 18 years+ - NCT03977233RecruitingPhase 2
Biopsies and FOLFIRINOX for non-metastatic pancreatic cancer
This Phase 2 study looks at different types (subtypes) of pancreatic tumors in people treated with FOLFIRINOX, a chemotherapy. It requires tumor biopsies before and after treatment to see how the tumor changes, which may help doctors better match treatments in the future.
Chapel Hill, North CarolinaAges 18–99 - NCT04030507Recruiting
Brain MRI screening during chemotherapy for breast cancer
This trial checks the brain using MRI in people with breast cancer that has spread outside the breast or can’t be fully removed. The goal is to screen for brain involvement and see how MRI findings fit with treatment timing, when it’s safe to do so.
Boston, MassachusettsAges 18 years+ - NCT04172753Recruiting
Online MRI-guided radiation therapy on a 1.5T machine
This trial checks whether it’s practical and safe to deliver radiation treatment using real-time MRI guidance, with the process supported online. It may help patients whose doctors recommend radiation by testing a modern way to plan and deliver treatment more precisely.
Tübingen, Baden-WurttembergAges 18 years+ - NCT04683679RecruitingPhase 2
Radiation plus pembrolizumab and olaparib for certain breast cancers
This study tests whether adding the drugs pembrolizumab and olaparib (or similar “radiosensitizers”) to radiation can improve outcomes for women with advanced breast cancer that is triple-negative or ER-positive/Her2-negative. It’s designed for cancers that have spread or come back and where radiation is being considered to control disease.
Basking Ridge, New JerseyAges 18 years+ - NCT04787744RecruitingPhase 2/Phase 3
Test standard prostate cancer treatment with or without targeted spot radiation
This study tests whether adding targeted local treatment (like radiation to a few spots seen on scans) improves outcomes for some people with limited (oligometastatic) prostate cancer. It compares standard systemic therapy alone versus standard therapy plus PET-scan–guided spot treatment.
Long Beach, CaliforniaAges 18 years+ - NCT04899908RecruitingPhase 2
Brain radiation with or without gadolinium nanoparticles for brain metastases
This trial tests whether adding tiny gadolinium-containing nanoparticles to standard brain radiation can better control brain metastases from certain cancers. It is for people with tumors that have grown after immunotherapy, are from certain cancers (like melanoma, GI, or HER2+ breast), are cystic, are large, or have come back after prior radiation.
Boston, MassachusettsAges 18 years+ - NCT04923178Recruiting
Natural history study of bladder and other genital cancers
This study follows people with urothelial cancer and certain rare genital (genitourinary) cancers over time to learn how these diseases progress. It may help researchers understand patterns of symptoms and outcomes, even if it is not a drug trial.
Bethesda, MarylandAges 18 years+ - NCT04969315RecruitingPhase 1/Phase 2
Drug TT-10 and TT-4 for advanced solid tumors
This early-phase trial tests two investigational drugs—TT-10 and TT-4—alone and together in people with advanced solid cancers. The study is designed to find safe doses and see if the treatment can shrink tumors or slow cancer growth.
Los Angeles, CaliforniaAges 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 - NCT05010109Recruiting
Testing heart safety and fitness during lung cancer chemoradiation
This study looks at how lung cancer treatment affects the heart and whether a “walking test” and blood tests can track heart fitness and injury. It may help by improving how cancer therapy is planned and monitored for heart safety.
Houston, TexasAges 18 years+ - NCT05051722Recruiting
Test DNA blood and tissue markers to detect gynecologic cancers
This study looks for “methylated DNA markers” (special DNA patterns) to help detect endometrial, ovarian, and cervical cancers, and to support doctors around planned procedures. It may help find cancer earlier or better sort out who needs closer treatment.
Phoenix, ArizonaAges 18 years+ - NCT05053230Recruiting
At-home integrative program for people living with cancer
This study tests an at-home integrative medicine program (supportive, whole-person care) to see if it helps symptoms like fatigue for people affected by cancer. You may be assigned to the program or a comparison group, and you’ll complete questionnaires and study check-ins from home.
Basking Ridge, New JerseyAges 18 years+ - NCT05076760RecruitingPhase 1
Study of a cancer-killing virus with standard treatments
This Phase 1 trial tests MEM-288, an oncolytic (cancer-killing) virus, either alone or combined with standard cancer medicines, in people with advanced solid tumors. It’s designed to see how the treatment works and how safe it is in different cancer types and after specific prior therapies.
Tampa, FloridaAges 18 years+ - NCT05187182RecruitingPhase 1
Testing a new cancer drug with FOLFOX and immune therapy
This Phase 1 study tests CA-4948 given with standard chemotherapy (FOLFOX) and an immune therapy (an immune checkpoint inhibitor, similar to PD-1). It’s for people with advanced stomach or esophageal cancer that can’t be removed by surgery, to see how well the treatment works and whether it’s safe.
St Louis, MissouriAges 18 years+ - NCT05281237Recruiting
Microwave ablation for small early lung cancer nodules
This trial studies a flexible “microwave heating” probe placed through the airways to treat small lung cancer nodules. It may help some patients avoid more invasive treatment by destroying the tumor during a bronchoscopy procedure.
Boston, MassachusettsAges 22 years+ - NCT05352178RecruitingPhase 3
Targeted treatment for few-spread prostate cancer spots
This Phase 3 trial tests whether treating only a small number of prostate cancer metastases can help people with “oligorecurrent” (limited repeat) prostate cancer. It may reduce cancer activity while avoiding broader whole-body treatment for some patients.
LeuvenAges 18 years+ - NCT05375266Recruiting
Study of immune signals in head and neck cancer
This study looks at “immune signals” in blood, saliva, and stool to learn more about head and neck cancers (especially squamous cell carcinoma). It may help researchers find patterns that improve understanding of disease or how treatment should be guided.
Erlangen, BavariaAges 18 years+ - NCT05396612Recruiting
Studying the immune response in non-cancer-spread breast surgery
This study looks at how your immune system changes while you receive standard breast cancer treatment around the time of surgery. The goal is to learn why some people respond better than others, which could help future treatment choices.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05398302RecruitingPhase 1
Biopsies during prostate cancer treatment to study resistance
This early study uses image-guided biopsies (small tissue samples taken with imaging) to learn why metastatic prostate cancer may stop responding to PSMA radioligand therapy. The results may help doctors understand resistance and improve future treatments.
Los Angeles, CaliforniaAges Any age - NCT05426135Recruiting
AI tool to assess cancer risk and guide care
This study tests an artificial intelligence (AI) system that uses your health information and medical images to better judge cancer risk and support diagnosis and treatment decisions. It may help doctors make more consistent assessments by combining clinical records, imaging, and other lab-style data.
Wuhan, HubeiAges 18–75 - NCT05452213RecruitingPhase 4
Study patterns of ribociclib response and resistance in breast cancer
This trial looks at how well ribociclib works and why it may stop working over time in people with advanced, hormone-receptor–positive, HER2-negative breast cancer. It also analyzes blood and tissue samples to help researchers understand resistance patterns and improve future treatment decisions.
Erlangen, BavariaAges 18 years+ - NCT05508906RecruitingPhase 1
Test drug OP-1250 with other medicines in ER-positive breast cancer
This Phase 1b study tests OP-1250 (palazestrant) combined with other targeted medicines for ER-positive, HER2-negative advanced or metastatic breast cancer. It mainly looks at safety and correct dosing, but may also help shrink tumors or slow growth.
