It may help your immune system recognize your specific tumor features.
Orange, CaliforniaAges 18 years+ - NCT03694756Recruiting
Testing special MRI to see tiny breast cancer structures
This study is testing whether a special MRI scan can help show tiny features inside breast tumors (TMEM). It’s mainly a “feasibility” study, meaning the team is checking if the scan can be done safely and clearly in different types of operable breast cancer.
The Bronx, New YorkAges 18 years+ - NCT03740256RecruitingPhase 1
HER2-targeted oncolytic virus plus custom immune cells for solid cancers
This Phase 1 study tests a treatment plan that combines a virus designed to attack cancer with your own custom immune cells that target HER2. It aims to shrink advanced HER2-positive solid tumors (and make future options safer/more effective).
Houston, TexasAges 18 years+ - NCT03755739RecruitingPhase 2/Phase 3
Checkpoint cancer drug given into or near tumors
This trial studies whether giving immunotherapy “checkpoint inhibitor” medicine directly into the tumor area (and/or the artery feeding it), along with a chemotherapy-style drug, can work better for advanced solid tumors. It aims to boost the immune system’s ability to attack cancer while still being safe for people with measurable tumors.
Guanzhou, GuangdongAges 18 years+ - NCT03787056Recruiting
Blood test marker study in many cancer types
This study measures a blood marker called progastrin (at diagnosis and during treatment) to see how well it predicts response or outcomes. It may help doctors choose or monitor treatment more precisely for several cancer types.
BronAges 18 years+ - NCT03788213Recruiting
Shorter vs longer radiation after breast cancer surgery
This trial compares giving breast radiation over one week versus three weeks after surgery. It aims to see whether the shorter schedule works just as well and is safe for people with certain types of early breast cancer.
Kolkata, West BengalAges 18 years+ - NCT03941756Recruiting
Lymph bypass before underarm node surgery to prevent swelling
This study looks at whether adding a lymph “bypass” procedure before underarm lymph node surgery can lower the chance of arm or chest swelling (lymphedema) after cancer treatment. It compares people having lymph node surgery for breast cancer with plans for radiation, and a melanoma comparison group.
Houston, TexasAges 18 years+ - NCT03946202RecruitingPhase 2
Radiation plus an in-tumor drug for breast cancer
This Phase 2 trial tests adding a drug inside the tumor (an “in-tumor” injection) to make radiation work better for locally advanced or recurrent breast cancer. It’s meant to help control the tumor area for better long-term local symptom control.
Trivandrum, KeralaAges 18 years+ - NCT03971045RecruitingPhase 2
Pembrolizumab plus low-dose oral chemo for chest wall breast cancer
This Phase 2 trial tests pembrolizumab (an immune therapy) plus low-dose oral cyclophosphamide in people with chest wall breast cancer that has spread locally and may have distant metastases. It aims to see if this combination can shrink tumors and control cancer longer, especially in tumors with certain immune markers.
MilanAges 18 years+ - NCT04090567RecruitingPhase 2
Olaparib with two partners for advanced BRCA breast cancer
This trial tests whether the drug olaparib works better when combined with cediranib or AZD6738 in people with advanced or metastatic BRCA (inherited) breast cancer. It may help shrink tumors or slow cancer growth after prior treatment with a PARP inhibitor.
Houston, TexasAges 18 years+ - NCT04134780Recruiting
Ultrasound tests to spot early breast cancer treatment response
This study uses special ultrasound imaging (and may use MRI results) to look for early signs of how locally advanced breast cancer responds to chemotherapy, with or without radiation. If the imaging changes early, it could help doctors adjust treatment sooner.
Houston, TexasAges 18 years+ - NCT04159142RecruitingPhase 2
Testing two chemo combos for advanced triple-negative breast cancer
This Phase 2 trial compares two chemotherapy combinations to see which works better for advanced triple-negative breast cancer. You would be asked to join one treatment arm based on study assignment and be followed for response and side effects.
Shijiazhuang, HebeiAges 18–70 - NCT04222413RecruitingPhase 1
Metarrestin for advanced solid tumors that spread
This Phase 1 trial studies metarrestin to see how safe it is and how well it works in people with advanced solid cancers that have spread or come back. You may be eligible if standard treatment options are no longer working or aren’t available.
Fairway, KansasAges 12–120 - NCT04503265RecruitingPhase 1/Phase 2
AMXI-5001 study for advanced cancers that won’t respond
This Phase 1/2 trial tests AMXI-5001 in people with advanced cancers that have progressed or stopped responding to standard treatments. It’s mainly designed to find the safest dose and see early signs the treatment might work.
Los Angeles, CaliforniaAges 18 years+ - NCT04540692RecruitingPhase 3
Testing chemotherapy timing for certain HER2-negative breast cancers
This Phase 3 trial studies different ways of giving common chemotherapy drugs (anthracyclines and taxanes) for locally advanced breast cancer that is HER2-negative. It aims to see which order or “sequencing” may work better for people like you.
Cachoeiro de Itapemirim, Espírito SantoAges 18 years+ - NCT04543799Recruiting
Sleep quality study in prostate and early breast cancer patients
This trial studies how sleep quality changes while people with prostate cancer or early breast cancer receive standard treatments. It may help doctors understand which treatment factors affect sleep and identify who might benefit from support for sleep problems.
BellinzonaAges 18 years+ - NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers
This early-phase study tests PC14586 (rezatapopt) in people with advanced or metastatic solid cancers that carry a specific TP53 mutation called Y220C. It mainly looks at safety and how well the treatment may work, sometimes combined with pembrolizumab.
Irvine, CaliforniaAges 12 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+ - NCT04771520RecruitingPhase 2
Avapritinib for tumors with specific KIT or PDGFRA changes
This Phase 2 trial studies avapritinib, a targeted medicine, for people whose cancer has specific KIT or PDGFRA genetic changes. It may help shrink or slow growth of certain advanced cancers, including some brain tumors, when standard treatments have not worked or for specific glioblastoma cases.
Houston, TexasAges 18 years+ - NCT04802759RecruitingPhase 1/Phase 2
Testing drug combinations for recurrent or advanced ER-positive breast cancer
This early-phase trial tests several combinations of cancer medicines to slow or control ER-positive breast cancer that has returned or progressed. It also checks safety and whether tumor or blood biomarkers can help match the right treatment to the right person.
Duarte, CaliforniaAges 18 years+ - NCT04842812RecruitingPhase 1
Personalized immune cell therapy for advanced solid tumors
This Phase 1 study tests engineered immune cells (TILs/CAR-TILs) made from your tumor to treat advanced solid cancers that have not responded to standard treatments. It may help your immune system better recognize and attack the cancer, but it is mainly focused on safety and early results.
