First treatment chemotherapy study for newly diagnosed Hodgkin lymphoma
This trial studies the best first chemotherapy approach for people newly diagnosed with classical Hodgkin lymphoma. It may help improve outcomes by comparing how treatment is given in routine care settings in Russia.
Mumbai, Opd-81 Main Building, Dr. E Borges Road, Parel 400012Ages 18–50 - NCT04641936Recruiting
Urine tests to predict response to immunotherapy in bladder cancer
This study uses urine “omics” tests (detailed lab patterns from urine) to predict whether immunotherapy will work for people with metastatic urothelial (bladder/urinary tract) cancer. It may help doctors choose the right treatment sooner by identifying who is more likely to benefit.
TaipeiAges 20 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+ - NCT04642027RecruitingPhase 3
PSMA scan-guided salvage radiation after prostate surgery
This trial tests whether using a specialized PSMA PET scan to guide radiation can better treat prostate cancer that returns after prostate surgery. It targets the “prostate bed” area with a shorter, stronger radiation schedule (hypofractionated) to control rising PSA levels.
Arnhem, GelderlandAges 18–80 - NCT04643041Recruiting
Watch-and-wait after PD-1 for certain rectal cancer
This study looks at whether people with a very strong response to a PD-1 antibody can safely delay or avoid more standard rectal cancer treatment (a “watch-and-wait” approach). It may help some people avoid surgery, radiation, or ongoing treatment while still closely monitoring the cancer.
Guangzhou, GuangdongAges 18–80 - NCT04644016RecruitingPhase 2
Cord blood transplant for children and young adults with blood cancers
This Phase 2 trial studies using a cord blood transplant after finding it is risky enough that standard treatment may not be sufficient. It may help certain children and young adults with specific leukemia, lymphoma, and some non-cancer blood/immune or inherited disorders who do not have a well-matched donor available in time.
New York, New YorkAges Up to 21 years - NCT04644211RecruitingPhase 2
Ruxolitinib for symptom control in certain blood cancer types
This Phase 2 study tests ruxolitinib (a targeted medicine) in people with essential thrombocythemia or polycythemia vera who still have troublesome symptoms. It aims to see whether it can reduce symptoms by changing disease activity and blood-related inflammation.
Boston, MassachusettsAges 18 years+ - NCT04644952Recruiting
Study of robotic lung segment surgery outcomes
This study looks at people who had a lung surgery called a segmentectomy with robotic assistance in the past. It aims to understand how these surgeries are done over time and what outcomes result for patients.
Houston, TexasAges Any age - NCT04645160RecruitingPhase 1/Phase 2
Tivozanib for bile duct and gallbladder cancers after chemotherapy
This Phase 1/2 trial tests tivozanib (a targeted anti-cancer drug) in people with bile duct or gallbladder cancer that cannot be removed by surgery and has already been treated with first-line chemotherapy. The study looks at how well the drug works and how safe it is in this setting.
Bethesda, MarylandAges 18 years+ - NCT04644289RecruitingPhase 2
Olaparib plus durvalumab for early testing in ovarian cancer
This study tests whether olaparib and durvalumab given around the time of diagnosis can help people with advanced ovarian cancer. It also strongly focuses on collecting tumor and blood samples to better understand who may benefit.
Mannheim, Baden-WurttembergAges 18 years+ - NCT04645199Recruiting
Long-term follow-up study for blood and bone marrow diseases
This study is collecting long-term follow-up information from people diagnosed with certain blood and bone marrow conditions. It may help doctors understand what happens over time and improve future care, but you’re mainly contributing data rather than receiving a new treatment.
Tianjin, Tianjin MunicipalityAges Any age - NCT04646759RecruitingPhase 3
Fulvestrant or capecitabine plus pyrotinib for metastatic breast cancer
This Phase 3 trial tests adding pyrotinib to standard hormone-based treatments (fulvestrant or capecitabine) to slow or control metastatic breast cancer. It’s for tumors that are hormone-receptor positive and HER2 positive, where standard options have been used before.
Guangzhou, GuangdongAges 18–80 - NCT04648462Recruiting
Proton therapy planning for certain brain tumors
This study builds and tests how proton therapy planning could better protect the brain compared with standard radiation (photon therapy) for adults with certain brain tumors. It may help reduce radiation to sensitive areas like the hippocampus, with the goal of better long-term brain function.
Maastricht, LimburgAges 18 years+ - NCT04650256Recruiting
Chinese herbal add-on after breast surgery
This trial looks at whether a Chinese herbal complementary treatment used alongside standard radiation after breast cancer surgery can improve health outcomes. It is for women newly diagnosed with certain stages of breast cancer who are planning chest-wall radiation.
Miami, FloridaAges 18 years+ - NCT04650880Recruiting
Vitamin D study for irregular periods from PCOS
This trial studies whether taking vitamin D can improve ovulation (the release of an egg) in people with PCOS who have long, irregular menstrual cycles. It may help some participants have more regular ovulation and cycle timing, but you would be monitored with vaginal ultrasound and blood tests.
Hong KongAges 18–40 - NCT04650919Recruiting
Rehabilitation graft after larynx removal for upper airway cancer
This trial tests a special “rehabilitation graft” used after total laryngectomy (complete larynx removal) for upper airway cancer. The goal is to improve recovery and function after surgery by using a graft designed to support healing and rehabilitation.
StrasbourgAges 18 years+ - NCT04652609Recruiting
Exercise program to prevent nerve damage from chemotherapy
This trial studies an exercise program (PRESIONA) that may help prevent nerve pain or numbness caused by a common type of breast cancer chemotherapy called taxane-based treatment. It targets people with HER2-positive breast cancer who are about to start neoadjuvant chemotherapy.
GranadaAges 18–70 - NCT04652180Recruiting
Robot surgery versus open surgery for esophagus cancer
This trial compares robot-assisted surgery with the standard open chest operation to remove esophagus and nearby tissue. It may help you understand which approach works better and is safer for patients whose cancer can be surgically removed.
L'Hospitalet de Llobregat, BarcelonaAges 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+ - NCT04654338RecruitingPhase 2/Phase 3
Two types of targeted radiation for favorable prostate cancer
This trial tests whether two “ablative” (high-dose, focused) radiation treatments can work well for men with favorable-risk prostate cancer. It looks at whether the treatments are practical and safe, especially for urinary side effects.
Toronto, OntarioAges Any age - NCT04654364Recruiting
Lung cancer registry that tracks patient information
This trial is a registry that collects information from people with certain types and stages of lung cancer. It helps researchers understand how these cancers are managed in real life, which can guide better future care.
Salzburg, State of SalzburgAges 18 years+ - NCT04655092RecruitingPhase 3
Extension study for people finishing prior P1101 treatment
This is an “extension” trial for people who already completed a 52-week P1101 study and agreed to continue. It tests whether continuing P1101 after the original study is safe and beneficial for certain patients.
Toon-shi, EhimeAges 20 years+ - NCT04654975Recruiting
Metastatic brain tumors after esophagus surgery study
This study looks at people who had esophageal cancer surgery and later developed brain metastases. It may help doctors better understand who benefits from treatment planning after the original cancer surgery.
Houston, TexasAges Any age - NCT04655404RecruitingEarly Phase 1
Larotrectinib for children with newly diagnosed glioma with NTRK fusion
This trial tests larotrectinib, a targeted cancer medicine, in children and teens with newly diagnosed high-grade brain glioma that has an NTRK fusion. It may help shrink or control tumors by targeting a specific genetic change in the cancer.
