This study looks at blood and tissue biomarkers to predict how well immunotherapy (with or without chemotherapy) works for advanced non-small cell lung cancer. It also helps decide the best second treatment if the first one stops working.
Goodyear, ArizonaAges 18 years+ - NCT06868433RecruitingPhase 1
TMV vaccine alone or with pembrolizumab for advanced HNSCC
This trial tests a vaccine made from your own tumor to help your immune system fight head and neck cancer that has returned or spread. It is given alone or with an immunotherapy drug (pembrolizumab) to see if it can shrink tumors or slow progression.
Atlanta, GeorgiaAges 18 years+ - NCT06735664RecruitingPhase 1
Zanubrutinib and odronextamab for Richter's transformation
This trial tests a combination of two targeted drugs for people with Richter's transformation, an aggressive lymphoma that can develop from CLL. The goal is to see if this combination can help control the disease.
Duarte, CaliforniaAges 18 years+ - NCT06723457RecruitingPhase 2
Epcoritamab and lenalidomide for immunodeficiency-related lymphoma
This trial tests a combination of two drugs, epcoritamab and lenalidomide, for patients with a rare type of large B-cell lymphoma linked to a weakened immune system. It is for people whose lymphoma did not improve or returned after standard treatments, and who cannot get CAR-T therapy.
Chicago, IllinoisAges 18 years+ - NCT06636734RecruitingPhase 2
Lovastatin plus pembrolizumab for advanced head and neck cancer
This trial tests whether adding lovastatin (a cholesterol-lowering drug) to pembrolizumab (an immunotherapy) works better than pembrolizumab alone for head and neck cancer that has come back or spread. It's for people who haven't had immunotherapy before and aren't already on a statin.
Atlanta, GeorgiaAges 18 years+ - NCT06470282RecruitingPhase 1/Phase 2
Drug combo plus radiation for muscle-invasive bladder cancer
This trial tests a combination of two drugs (enfortumab vedotin and pembrolizumab) plus radiation therapy for people with bladder cancer that has grown into the muscle layer. The goal is to see if this treatment can kill the cancer while avoiding the need for bladder removal surgery.
San Francisco, CaliforniaAges 18 years+ - NCT06439836RecruitingPhase 1
Combination immunotherapy for advanced bladder cancer
This trial tests a new drug, CA-4948, combined with pembrolizumab (Keytruda) for people with advanced bladder cancer that grew after prior immunotherapy. The goal is to see if this combination can help when standard treatments stop working.
Duarte, CaliforniaAges 18 years+ - NCT06323460RecruitingPhase 2
Less Radiation for HPV Throat Cancer Guided by a Blood Test
This study tests a way to use less radiation for HPV-related throat cancer. Doctors will adjust your treatment based on a simple blood test that tracks cancer DNA, so you may get only the treatment you need.
Columbus, OhioAges 18 years+ - NCT06029270RecruitingPhase 2
Adding relatlimab to standard immunotherapy for nasopharyngeal cancer
This trial tests whether adding a new drug called relatlimab to the usual immunotherapy (nivolumab) helps people with nasopharyngeal cancer that has returned or spread. You will get standard chemotherapy plus nivolumab first, then if it works, you may be randomly assigned to get nivolumab alone or with relatlimab.
Dublin, CaliforniaAges 18 years+ - NCT05518903RecruitingPhase 2
Scan test to see tumor-support cells in pancreatic cancer
This trial tests a special imaging scan (a PET/CT with a tracer called 68Ga-FAPI-46) to look at “cancer-support” cells in people with localized pancreatic ductal adenocarcinoma. It may help doctors better understand the tumor and how it responds before surgery after initial treatment.
