63 Clinical Trials for Various Conditions
This phase II trial studies how well cobimetinib and atezolizumab work in treating participants with rare tumors that have spread to other places in the body (advanced) or that does not respond to treatment (refractory). Cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cobimetinib and atezolizumab may work better in treating participants with advanced or refractory rare tumors.
Background: People with rare cancers often have limited treatment options. The biology of rare cancers is not well understood. Researchers want to find better treatments for these cancers. They want to test 2 drugs that, taken separately, have helped people with non-rare cancers. They want to see if these drugs together can make rare cancers shrink or stop growing. Objective: To learn if nilotinib and paclitaxel will benefit people with rare cancers. Eligibility: People age 18 and older who have a rare, advanced cancer that has progressed after receiving standard treatment, or for which no effective therapy exists. Design: Participants will be screened with medical history and physical exam. They will have blood and urine tests. They will have a pregnancy test if needed. They will have an electrocardiogram to check their heart. They will have imaging scans to measure their tumors. Participants will repeat the screening tests during the study. Participants will receive nilotinib and paclitaxel. The drugs are given in 28-day cycles. Nilotinib is a capsule taken by mouth twice a day. Paclitaxel will be given intravenously by peripheral line or central line once a week for the first 3 weeks of each cycle. Participants will keep a medicine diary. They will track when they take the study drugs and any side effects they may have. Participants may have optional tumor biopsies. Participants can stay on the study until their disease gets worse or they have intolerable side effects. Participants will have a follow-up phone call about 30 days after taking the last dose of study drugs.
This study will assess the effectiveness and safety of pasireotide long-acting release in patients who have rare tumors of neuroendocrine origin.
The goal of this study is to explore cognitive burden perceptions among physicians in relation to case report writing. Furthermore, this study evaluates the use of artificial intelligence (AI) assistance as a tool to reduce cognitive burden among providers preparing and submitting case reports. If an AI-tool is helpful in this setting, it may potentially help increase reporting of rare medical events and thereby improve the evidence base for care of these patient populations. This study will occur at a single time point which is expected to last approximately 2 hours. This session will include reviewing two rare tumor cases and then writing a clinical vignette with and without AI assistance.
Background: Some people may be prone to develop cancer for many reasons. Factors that affect their risk include the genes they inherit and the environment they live and work in. Researchers want to learn more about the natural history of cancer. Objective: To understand how genes and environmental factors can cause tumors and related conditions. Eligibility: People of any age who: Have tumors of an unusual type, pattern, or number Have a family member with a history of cancer Have been exposed to other factors that may increase their risk of cancer Design: This study does not involve treatment. Participants will answer questions about their personal and family medical history. They will give permission for researchers to see their medical records. Participants may be invited to the NIH Clinical Center for a physical exam. They may give samples including saliva, cheek cells, blood, urine, skin, and/or hair. Participants with cancer may give bone marrow. A needle will be used to remove a small sample of bone marrow from their hip bone. Participants may have a biopsy of their tumor. Participants may have other exams: Dental Ear, nose, and throat Eye Hearing Heart function and structure Participants with cancer may undergo more exams: A test of how much energy their body uses when resting A sleep study with a test that measures brain electrical activity. They will have sensors attached to their body while they sleep overnight in a lab. Imaging scans, such as CT, MRI, a test to measure how dense their bones are (DEXA), and ultrasound. Participants will have their genes tested. A counsellor will help them understand the results. Participants will be followed until at least 2035.
To test the safety of and effectiveness of XmAb20717 for participants with advanced rare cancers.
This open label, non-randomized, multi-center, pragmatic study aims to establish whether patients with rare tumors can benefit from matched molecular therapy as dictated by their next-generation sequencing (NGS) results.
This phase II trial studies how well pembrolizumab works in treating patients with rare tumors that cannot be removed by surgery or have spread to other parts of the body. Monoclonal antibodies, such as pembrolizumab, may block specific proteins found on white blood cells which may strengthen the immune system and control tumor growth.

Study hypothesis: Trastuzumab deruxtecan will show meaningful clinical activity and a favorable risk benefit profile in selected HER2-expressing solid tumors.
The purpose of this study is to test, customize, and personalize a mobile app-based intervention program in order to help rare and breast cancer survivors cope with fears of cancer recurrence.
Background: Chordoma is a rare type of bone cancer. It occurs in the skull base or spine. Researchers want to study people with chordoma in different ways. They hope this will help them design better future treatments and supportive care studies for this disease. Objective: To learn more about chordoma by looking at its clinical course, how it appears on imagine scans, and how it responds to therapies and treatments. Eligibility: People ages 2 and older with chordoma who are enrolled in NCI protocol 19-C-0016 Design: Participants will be screened with their medical history. Participants will have a visit to examine their disease. This will include: * Physical exam * Neurologic exam * CT scan and MRI: Participants will lie on a table. The table will slide into a machine. The machine will take pictures of the body. Participants will have other tests every 6-12 months: * Smell test * Surveys to assess their emotional, physical, and behavioral well-being and needs * Cognitive function tests Participants or their home doctors will be contacted every 6 12 months. They will be asked to provide information about their disease. This could include test results and imaging evaluations. Some participants may be asked to come to the clinic for more visits.
Background: - Adrenocortical carcinoma (ACC) is a rare tumor of the adrenal gland. Few people who develop this disease live more than 5 years after being diagnosed. Those whose tumors have spread inside their abdomen may have an especially poor outcome. In these cases, traditional chemotherapy is not very effective. One possible new treatment is aggressive surgery with heated chemotherapy. This type of treatment has been more effective for other types of cancer in the abdomen. Researchers want to see this if approach can improve the outcomes of people with ACC. Objectives: - To test the safety and effectiveness of surgery and heated chemotherapy for ACC. Eligibility: - Individuals at least 18 years of age who have advanced ACC. Design: * Participants will be screened with a physical exam and medical history. Blood samples will be collected. Heart function tests will be given. Imaging studies will be used to locate the surgical sites before the operation. * Participants will have surgery to remove ACC tumor tissue. After the tumors have been removed, they will have heated chemotherapy with cisplatin. The heat may help weaken any remaining cancer cells and make them easier to destroy. It will also focus the treatment on the tumor sites, rather than the whole body. * Participants will recover in the hospital for several days after surgery. They will have regular follow-up visits to monitor the outcome of the surgery.
Background: Rare tumors of the genitourinary (GU) tract can appear in the kidney, bladder, ureters, and penis. Rare tumors are difficult to study because there are not enough people to conduct large trials for new treatments. Two drugs-sacituzumab govitecan (SG) and atezolizumab-are each approved to treat other cancers. Researchers want to find out if the two drugs used together can help people with GU. Objective: To test SG, either alone or combined with atezolizumab, in people with rare GU tumors. Eligibility: Adults aged 18 years and older with rare GU tumors. These may include high grade neuroendocrine carcinomas; squamous cell carcinoma of the bladder; primary adenocarcinoma of the bladder; renal medullary carcinoma; or squamous cell carcinoma of the penis. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have tests of heart function. They will have imaging scans. They may need a biopsy: A small needle will be used to remove a sample of tissue from the tumor. Both SG and atezolizumab are given through a tube attached to a needle inserted into a vein in the arm. All participants will receive SG on days 1 and 8 of each 21-day treatment cycle. Some participants will also receive atezolizumab on day 1 of each cycle. Blood and urine tests, imaging scans, and other exams will be repeated during study visits. Treatment may continue for up to 5 years. Follow-up visits will continue for 5 more years.
Background: Many cancers of the testicles and urinary tract are rare diseases; these are diseases that affect less than 200,000 people in the United States. It can be hard to study treatments for these diseases. One combination of drugs-enfortumab vedotin (EV) and pembrolizumab-has already been approved to treat some urinary cancers. Researchers want to see if they can help people with other types of testicle and urinary cancers. Objective: To test EV, with or without pembrolizumab, in patients with rarer cancers of the testicles or urinary tract. Eligibility: People aged 18 and older with rarer cancers of the testicles or urinary tract. Design: Participants will be screened. They will have a physical exam with blood and urine tests. Their ability to perform normal daily activities will be tested. They will have exams of their skin and eyes. They will have imaging scans. A biopsy may be needed: A sample of tissue will be removed from the tumor. The study drugs are both given through a tube attached to a needle inserted into a vein in the arm. Some participants will receive treatments 3 times during 28-week cycles; others will receive treatments 2 times during 21-day cycles. All participants may continue to receive treatments for up to 5 years. Imaging scans and other tests will be repeated. Participants who stop taking the drugs will have follow-up visits every 3 to 4 weeks until the disease gets worse. They will have imaging scans and blood tests. After that, follow-up visits will continue by phone every 3 months for up to 5 years after study therapy is finished.
The objective of the International Rare Brain Tumor Registry (IRBTR) is to better understand rare brain tumors through the collection of biospecimens and matched clinical data of children, adolescents, and young adult patients diagnosed with rare brain tumors.
This phase II trial studies how well 177Lu-DOTATATE works in treating patients with rare endocrine cancers that have spread from where they started to nearby tissue or lymph nodes (locally advanced), spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Radioactive drugs, such as 177Lu-DOTATATE, may carry radiation directly to cancer cells and not harm normal cells. 177Lu-DOTATATE may help to control endocrine cancers compared to standard treatment.
Background: Approximately 150 cases of cancer per one million per year are considered rare cancers. While all tumors originate from genetic changes, a small percentage of these tumors are familial. Researchers want to study these changes in biological samples from people with rare tumors in order to learn more about how these tumors develop. The information obtained from this study may lead to improved screening, preventive guidelines, and treatments. Objective: To better understand rare cancers and hereditary cancer syndromes. Eligibility: People who have a rare tumor, a family history of a rare tumor, a hereditary cancer syndrome, or a mutation that leads to rare tumors. Design: Participants will be screened with questions about their medical history and/or that of their family members. They will give a saliva sample. Participants who have a tumor will have their medical records and tests reviewed. They will answer questions about their wellbeing and needs. They may provide a tumor tissue sample. Participants may also have: * Physical exam * Clinical photography * Blood, urine, saliva, and stool samples taken * Consultation with specialists * A scan that produces a picture of the body. Either one that uses a small amount of radiation, or one that uses a magnetic field. * Genetic testing/genetic counseling. Participants will be contacted once a year. They will answer updated questions about their medical and family history. Participants will be asked to contact the study team if there are changes in their tumors. Participants may be invited to join focus groups for people with the same diagnosis of rare tumors. Participants may be invited to participate in other NIH protocols. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* RARE TUMOR LIST: 1.

Background: More than 130 primary tumors of the central nervous system (CNS) have been identified. Most affect less than 1,000 people in the United States each year. Because these tumors are so rare, there are few proven therapies. This study will test whether the immunotherapy drug nivolumab is an effective treatment for people with rare CNS tumors. Objectives: To learn if stimulating the immune system using the drug nivolumab can shrink tumors in people with rare CNS (brain or spine) tumors or increase the time it takes for these tumors to grow or spread. Eligibility: Adults whose rare CNS tumor has returned. Design: Individuals will be screened: * Heart and blood tests * Physical and neurological exam * Hepatitis tests * Pregnancy test * MRI. They will lay in a machine that takes pictures. * Tumor tissue sample. This can be from a previous procedure. At the start of the study, participants will have blood tests. They will answer questions about their symptoms and their quality of life. Individuals will get nivolumab in a vein every 2 weeks for up to 64 weeks. Individuals will have monthly blood tests. Every other month they will have an MRI and a neurologic function test. They will also answer questions about their quality of life. Genetic tests will be done on individuals' tumor tissue. Individuals will be contacted if any clinically important results are found. After treatment ends, individuals will be monitored for up to 5 years. They will have a series of MRIs and neurological function tests. They will be asked to report any symptoms they experience....
This phase II trial studies how well atezolizumab and bevacizumab work in treating patients with rare solid tumors. Immunotherapy with monoclonal antibodies, such as atezolizumab and bevacizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
This is an investigator initiated single institution, open-label study to evaluate the antitumor activity, safety, and tolerability of durvalumab in combination with tremelimumab in subjects with select advanced rare solid tumors.
The purpose of this sub-study is to provide expanded access of AZEDRA (Ultratrace Iobenguane I 131) and to evaluate the safety and tolerability of AZEDRA in subjects with iobenguane-avid malignant and/or recurrent pheochromocytoma/paraganglioma (PPGL).
Background: - Cabozantinib is a cancer treatment drug that blocks the growth of new blood vessels in tumors. It can also block a chemical on tumor cells that allows the cells to grow. A similar drug, pazopanib, is used to treat types of cancer known as sarcomas. Researchers want to see if cabozantinib can be an effective treatment for types of soft tissue sarcoma that have not responded to earlier treatments. Objectives: - To test the effectiveness of cabozantinib for soft tissue sarcomas that have not responded to standard treatments. Eligibility: - Individuals at least 18 years of age who have soft tissue sarcomas that have not responded to standard treatments. Design: * Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies and other tests will be used to study the tumor before the start of treatment. * Participants will take cabozantinib tablets daily for 28-day cycles of treatment. The tablets should be taken whole on an empty stomach. * Treatment will be monitored with frequent blood tests and imaging studies. * Participants will continue to take cabozantinib for as long as the tumor does not become worse and the side effects are not too severe.
Background: Chordoma is a rare, slow growing, often fatal bone cancer derived from remnants of the embryonic notochord. It occurs mostly in the axial skeleton (skull base, vertebrae, sacrum and coccyx), is more frequent in males than females, and has a median age at diagnosis of 58.5 years, with a wide age range. This typically sporadic tumor is often advanced at presentation, and mortality is high due to local recurrence or distant metastases. The usual treatment is surgery, followed by adjuvant radiation therapy. Chemotherapy has not had a significant treatment role. Reports of a small number of families worldwide with two or more relatives with chordoma support a role for susceptibility genes in chordoma etiology. Recently we determined that duplications of the T gene co-segregated with disease in four multiplex chordoma families. The T gene encodes brachyury, a tissue-specific transcription factor that is expressed in notochord cells and is essential for formation and maintenance of the notochord. Some of the other chordoma families that we studied did not have T-gene duplications; the aggregation of chordomas in these families may result from changes in other susceptibility genes or other types of mutations targeting the T gene. We are continuing gene identification studies of multiplex chordoma families at the NIH Clinical Center under protocol 78-C-0039. We also want to determine whether alterations in any identified chordoma susceptibility genes are associated with sporadic chordoma in the general population. Objectives: The major goal of this protocol is to identify sporadic chordoma patients willing to provide germline and tumor DNA for studies to determine the frequency of alterations in chordoma susceptibility genes. Our previous protocols with SEER and Massachusetts General Hospital to identify chordoma patients were limited to residents of specific geographic regions in the U.S. (2 states and 2 metropolitan areas) or to patients with pediatric skull base tumors. This protocol will enroll patients who more broadly represent the age, site and gender distributions of sporadic chordoma in the general U.S. population. Eligibility: Eligible patients are males and females in the U.S. with chordoma diagnosed at any age and at any primary site. Because we want to obtain saliva from all participants, eligibility is limited to patients who will be greater than or equal to age 6 years at the time of enrollment. Design: The study description and contacting information including an e-mail link to the study contact person will be posted on web sites of two chordoma support groups. We will mail study information to be given to patients to colleagues at major medical centers that treat chordoma. The components of the study will be carried out in subjects' homes using materials mailed to them. Up to 100 participants will: 1) complete a self-administered Personal and Family Medical History Questionnaire, 2) collect saliva using a saliva collection kit, and 3) provide permission to obtain medical/pathology records, and paraffin blocks or slides on each primary chordoma. Parents will serve as proxies for minor children. We will recontact patients who report chordoma in at least one blood relative. If we confirm the relative's chordoma diagnosis, we will invite the study subject and selected family members to participate in clinical and gene mapping studies under protocol 78-C-0039. We may also recontact study participants to tell them about any new studies on chordoma etiology. They can decide at that time whether they want to participate in them.
Master protocol: The goal of this master clinical study is to test how well the study drug, brexucabtagene autoleucel, works in participants with rare B-cell malignancies: relapsed/refractory Waldenstrom macroglobulinemia (r/r WM) (Substudy A - no longer recruiting), relapsed/refractory Richter transformation (r/r RT) (Substudy B), relapsed/refractory Burkitt lymphoma (r/r BL) (Substudy C and relapsed/refractory hairy cell leukemia (r/r HCL) (Substudy D - no longer recruiting).
