Cancer patients share experiences during the COVID-19 outbreak
This study asks adult cancer patients to complete a survey and talk in an interview about how COVID-19 affected their care and daily life. Your answers may help researchers understand what challenges cancer patients faced during the pandemic.
Stanford, CaliforniaAges 18–99 - NCT04332367RecruitingPhase 2
New chemo plus ramucirumab for lung cancer after maintenance
This Phase 2 trial studies a combination of chemotherapy (carboplatin and a “taxane”) plus ramucirumab for people with advanced lung cancer that came back or progressed after prior maintenance treatment. It may help by attacking cancer growth after earlier therapy no longer worked.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04335292RecruitingPhase 2
Osimertinib then chemotherapy for EGFR-mutated lung cancer
This Phase 2 study tests a treatment sequence starting with osimertinib, then using chemotherapy after it. It is meant for people with EGFR-mutated advanced lung cancer whose disease has come back or progressed, including a “rechallenge” attempt with osimertinib.
Vancouver, British ColumbiaAges 18 years+ - NCT04342546Recruiting
Radiation skin side-effect test after mastectomy with implant
This trial looks at a test meant to predict how likely you are to develop side effects from radiation to the chest wall after mastectomy. It is designed for people getting immediate breast reconstruction using an implant, so treatment planning may be safer and more personalized.
DijonAges 18 years+ - NCT04341181RecruitingPhase 2
Targeted cancer treatment chosen by tumor genetic test results
This Phase 2 trial matches people with advanced cancer to a targeted treatment based on a genetic (DNA) or protein (IHC) test from their tumor. It’s for cancers that are no longer responding to standard treatment or where no standard option is available.
Aalborg, AalborgAges 18 years+ - NCT04344496Recruiting
Collecting breast cancer tissue to predict recurrence risk
This study builds a “genome atlas” to better predict the chance that breast cancer will come back. It asks participants to share medical information and provide blood and tumor tissue samples, including samples kept in paraffin.
TaipeiAges 20 years+ - NCT04353557Recruiting
Blood test monitoring in early-stage breast cancer
This trial uses a special blood test to track cancer signals (called ctDNA) during and after treatment for early breast cancer. It aims to see whether monitoring these signals can help guide follow-up and treatment decisions.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT04356209RecruitingPhase 2
Pravastatin for severe radiation breast scar tissue, with e-reports
This trial tests whether pravastatin can improve severe radiation-related breast scarring and breast-related quality of life. It also studies whether using an electronic patient questionnaire (e-PRO) helps patients’ outcomes and support during treatment.
MontpellierAges 18 years+ - NCT04358913Recruiting
MRI scan study during radiation treatment planning
This study looks at how an MRI scanner can be used alongside a radiation treatment machine to plan therapy. It may help improve how radiation is targeted, though joining is mainly about whether you can safely and comfortably complete the MRI scans.
Edmonton, AlbertaAges 18 years+ - NCT04364373Recruiting
Test of different lymph node surgery for left colon cancer
This study compares two types of lymph node removal during surgery for left-sided colon cancer. It aims to see which surgical approach may work better while ensuring you can still safely complete chemotherapy.
MoscowAges 18–75 - NCT04373655Recruiting
Lymph node surgery after chemotherapy for invasive breast cancer
This trial studies how doctors should operate on lymph nodes after you finish chemotherapy given before surgery. It may help improve treatment planning for people whose breast cancer has spread to nearby lymph nodes, but not to distant organs.
Esslingen am NeckarAges 18 years+ - NCT04375904RecruitingPhase 2
Stereotactic radiation for central lung tumors
This trial tests a precise, high-dose radiation treatment aimed at central lung tumors. It may help people who cannot have lung surgery and whose tumors can be safely targeted near sensitive organs.
DublinAges 18 years+ - NCT04376229Recruiting
Proton radiation registry for people treated at the center
This study keeps a record of patients who receive proton radiation therapy at a specific center. It may help doctors learn how this treatment is used and how patients do over time.
Washington D.C., District of ColumbiaAges 18–100 - NCT04380545RecruitingPhase 1/Phase 2
Nivolumab plus chemo and immune drug for unresectable liver cancer
This Phase 1/2 trial tests whether nivolumab combined with fluorouracil and interferon alpha can treat fibrolamellar liver cancer that cannot be safely removed with surgery. It aims to shrink or control the cancer and to see how safe the combination is.
