Skin Condition in Youth: Long-Term Study
This study looks at the long-term health of people who were diagnosed with a rare skin lymphoma (mycosis fungoides) or a related skin condition (lymphomatoid papulosis) before age 20. Researchers want to learn how these conditions affect people over time.
Houston, TexasAges 18 years+ - NCT06210854RecruitingPhase 2
HPV16/18 Vaccine Trial for Cervical Lesions
This trial tests a new vaccine (pBI-11) given with a device that uses mild electric pulses to help the vaccine enter cells. It is for people who have HPV16 or 18 but no high-grade cervical changes.
Birmingham, AlabamaAges 18 years+ - NCT06218602RecruitingPhase 2
Fecal transplant for lymphoma patients getting CAR T therapy
This trial tests whether giving a fecal transplant (a stool enema from a healthy donor) can improve the response to CAR T-cell therapy in people with B-cell lymphoma. It may help by restoring healthy gut bacteria that are often wiped out by strong antibiotics.
Houston, TexasAges 18 years+ - NCT06216301RecruitingPhase 3
Electric fields with immunotherapy and chemo for advanced lung cancer
This trial tests adding a device that delivers electric fields (Tumor Treating Fields) to standard immunotherapy and chemotherapy for people with advanced non-small cell lung cancer that has not been treated before. It may help slow tumor growth.
Birmingham, AlabamaAges 18 years+ - NCT06207032Recruiting
Cancer biobank registry study
This study collects blood samples and health information from people diagnosed with cancer to build a research database. It may help future patients by enabling better understanding and treatment of cancer.
Birmingham, AlabamaAges 18–99 - 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+ - NCT04962867RecruitingPhase 2
Targeting FGFR changes in advanced, hard-to-treat cancers
This Phase 2 study tests a treatment aimed at specific FGFR (a cancer-growth signal) changes found in your tumor. It may help people whose cancer has spread, cannot be removed, or has stopped responding to standard treatment.
Chuo-ku, Tokyo, JapanAges 20 years+ - NCT06195527Recruiting
Pembrolizumab blood level monitoring for NSCLC
This study checks how well pembrolizumab (Keytruda) works in people with non-small cell lung cancer (NSCLC) by measuring the drug levels in your blood. It aims to see if adjusting the dose based on these levels improves treatment and reduces side effects.
AngersAges 18 years+ - NCT06182774RecruitingPhase 3
Fixed vs ongoing treatment for older adults with new myeloma
This trial compares stopping treatment after a set number of cycles versus continuing it for people over 65 or those who cannot have a stem cell transplant. It tests whether a fixed treatment period works as well as long-term treatment for newly diagnosed multiple myeloma.
Edmonton, AlbertaAges 18 years+ - NCT06183437RecruitingPhase 4
Can I stop heart meds after cancer therapy?
This trial tests whether it is safe to stop taking heart failure medications in people who developed heart weakness after cancer treatment but whose heart function has since recovered. It aims to see if stopping these drugs leads to any worsening of heart health.
