Cancer of unknown primary site

This early-phase trial tests a new drug called BI 764532 (Obrixtamig) given together with standard chemotherapy for people with advanced neuroendocrine carcinoma (NEC), a rare and fast-growing cancer. The study involves about 55 adults whose tumors have a specific marker (DLL3). …

This study looks at whether doctors can safely stop standard anti-PD-1 immunotherapy early in people with advanced melanoma that cannot be surgically removed. By using PET/CT scans and tumor biopsies as guides, the goal is to reduce treatment side effects and burden without harmi…

This phase 3 trial tests whether the immunotherapy drug ipilimumab is better than high-dose interferon alfa-2b at preventing melanoma from coming back in patients whose cancer was removed by surgery. Over 1,600 people with high-risk stage III or IV melanoma took part. The study m…

This early-phase study tests the safety and best dose of a drug called veliparib when given with two chemotherapy drugs (carboplatin and paclitaxel) in people with advanced solid tumors that have spread or can't be removed. It includes patients who also have liver or kidney probl…

This phase III trial compares the drug pembrolizumab (MK-3475) to the current standard treatments—high-dose interferon or ipilimumab—in 1,301 patients with high-risk melanoma that has been surgically removed. The goal is to see if pembrolizumab is better at preventing the cancer …

This study tests whether adding an experimental drug (CMP-001) to the immunotherapy pembrolizumab can better shrink melanoma tumors before surgery and help prevent them from coming back. About 60 adults with stage III or recurrent melanoma that can be surgically removed will rece…

This early-phase trial tests a new drug called berzosertib (M6620) alongside standard chemotherapy (cisplatin) and radiation in people with advanced head and neck cancer that has spread to nearby tissues. The main goals are to find the safest dose and to see what side effects occ…

This study tested a drug called pembrolizumab in 157 people with rare cancers that had spread or couldn't be removed. The drug works by helping the body's immune system attack the cancer. The main goal was to see how many patients were alive and their cancer hadn't grown after 27…

This study is testing whether a precise form of radiation called proton therapy can control head and neck cancer after surgery as well as standard X-ray radiation, but with fewer side effects. About 174 adults with newly diagnosed head and neck cancer will receive either proton t…

This phase 2 trial is testing a combination of two immunotherapy drugs, nivolumab and ipilimumab, in 798 people with over 50 types of rare cancers. The goal is to see if these drugs can shrink tumors by helping the immune system attack cancer cells. Participants receive the drugs…

This study tests whether combining two treatments—thermal ablation (using heat to destroy tumor cells) and stereotactic radiosurgery (precise, high-dose radiation)—can better control cancer that has spread to the spine and is pressing on the spinal cord. About 60 adults with vari…

This study tests a special bacteria (Clostridium novyi-NT) injected directly into tumors, combined with the immunotherapy drug pembrolizumab, for people with advanced solid tumors that haven't responded to standard treatments. The bacteria are designed to break down tumor cells f…

This phase 2 trial tests whether combining two immunotherapy drugs, atezolizumab and tiragolumab, can help control cancers of unknown primary (CUP) — cancers where doctors cannot find where the cancer started. Only 4 participants who have already tried chemotherapy are enrolled. …

This phase 1 trial is testing a new imaging tracer called 68Ga-FAPI-46 to see where it collects in normal and cancerous tissues. About 30 people with various solid tumors or blood cancers will receive the tracer and then undergo a PET/CT scan. The goal is to understand how the tr…

This study tests a surgical technique called tongue base mucosectomy, combined with detailed tissue analysis, to find the original site of head and neck cancers that have spread to lymph nodes but have no known primary source. About 100 patients will undergo this procedure, and r…

This early study tests a new radioactive tracer called 68Ga-FAPI-46, which targets a protein (FAP) found around many tumors. About 26 people with various cancers will get a PET/CT scan using this tracer to see where it goes in the body. The goal is to learn if this tracer can hel…

This early-phase study tests the safety of combining the drug tolinapant with radiation therapy for people with head and neck cancer that has spread locally but hasn't been treated yet. Participants are those who cannot receive the standard chemotherapy drug cisplatin. The goal i…

This study looks at tumor samples from over 3,000 people with advanced cancers to find specific biomarkers—unique features of each cancer. The goal is to help doctors choose the most promising targeted therapy or clinical trial for each patient. Participants are adults with vario…
