11 Clinical Trials for Various Conditions
The researchers are doing this study to compare the safety of vemurafenib in combination with obinutuzumab to the standard of approach of cladribine in combination with rituximab. The researchers will look at which treatment causes fewer or milder side effects. Researchers think vemurafenib and obinutuzumab (non-chemotherapy drugs) may cause fewer side effects compared with the usual approach of chemotherapy drugs. They will also compare the two approaches to see which approach is more effective at eliminating cancer cells.
Background: - Researchers who are studying hairy cell leukemia, and how the disease compares with other disorders, are interested in obtaining additional samples from leukemia patients and healthy volunteers. The investigators are particularly interested in samples from individuals who have diseases that can be treated with a new type of drug called immunotoxin, in which an antibody carrying a toxin binds to a cancer cell and allows the toxin to kill the cell. Objectives: - To collect a variety of clinical samples, including blood, urine, lymph samples, and other tissues, in order to study the samples and develop new treatments for leukemia. Eligibility: - Individuals 18 years of age and older who have been diagnosed with leukemia or other kinds of blood and lymphatic system cancers, or who are healthy volunteers. Design: * Individuals who have leukemia will be asked to provide blood, bone marrow, urine, and tumor tissue samples as requested by the researchers. Healthy volunteers will provide only blood and urine samples. * No treatment will be given as part of this protocol.
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of AGS67E both without and with myeloid growth factor (GF) in subjects with refractory or relapsed lymphoid malignancies. Immunogenicity and anticancer activity of AGS67E will also be assessed.
This was a Phase II, open-label, non-randomized, multi-center study of oral dabrafenib in combination with oral trametinib in subjects with rare cancers harboring the BRAF V600E mutation including anaplastic thyroid cancer (ATC), biliary tract cancer (BTC), gastrointestinal stromal tumor (GIST), low grade (WHO G1/G2) glioma (LGG), high grade (WHO G3/G4) glioma (HGG), non-seminomatous germ cell tumors (NSGCT) / non-germinomatous germ cell tumors (NGGCT), adenocarcinoma of the small intestine (ASI), hairy cell leukemia (HCL) and multiple myeloma (MM).
Background: * Mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), multiple myeloma (MM), and other lymphoid malignancies are all incurable lymphoid malignancies that mainly affect persons in their late 60s and early 70s. Conventional chemotherapy can achieve high rates of clinical response, but relapse following these responses is almost universal. Patients with lymphoid malignancies relapse because their tumor cells become resistant to chemotherapy; therefore, new types of drugs are needed for better treatment responses. * The investigational drug ON 01910.Na has been shown to be active against MCL and CLL cells, but further research is needed to determine the most safe and effective dose for this drug. Objectives: * To determine the maximum tolerated dose (the highest dose that does not cause unacceptable side effects) of ON 01910.Na in patients with cancers of the lymphoid cells. * To study the effects that ON 01910.Na has on cancers of the lymphoid cells. Eligibility: * Patients 18 years of age and older who have been diagnosed with cancer of the lymphoid cells, and who have not been able to take or have not benefitted from existing treatment options. Design: * Evaluations before the treatment period: * Full medical history and physical examination, and pregnancy test for women. * Blood and urine tests. * Disease evaluation with computerized tomography (CT) scan, magnetic resonance imaging (MRI), electrocardiogram; bone marrow and lymph node biopsies; and skeletal x-rays, if clinically indicated. * Treatment with ON 01910.Na: * Different research subjects will receive increasing doses of ON 01910.Na to determine which dose is considered safe. * To reduce the risk of one rare serious side effect of treatment for myeloid malignancies, patients will take allopurinol 12 hours before and 7 days after each drug infusion, one 300 mg pill each day. * Cycles 1 2: Patients will be admitted to the clinical center for 2 days at the beginning of each cycle. Each cycle involves intravenous infusion of ON 01910.Na continuously for a period of 48 hours, followed by 12 days of observation. Researchers will try to maintain the schedule of 2 days of infusion every 14 days, but the interval between doses may be extended if patients experience delayed recovery blood counts. * Cycles 3 4: Patients who are doing well and choose to continue may receive an additional two cycles (2 days of inpatient infusion followed by 12 days of outpatient observation). At the end of cycle 4, researchers will determine if the disease is responding to therapy. Patients who experience side effects may continue to take ON 01910.Na at a lower dose or may stop receiving the drug. * Patients who respond well to four cycles of ON 01910.Na may be eligible for additional cycles of ON 01910.Na. * Patients who need to start another medication to treat their disease will stop taking ON 01910.Na, and the researchers will perform a final study visit 2 weeks after the last dose of ON 01910.Na. After that, participation in the study will be complete.
Background: Hairy cell leukemia (HCL) does not usually respond to chemotherapy. Most people with HCL have a BRAF gene mutation. This can increase the growth of cancer cells. Vemurafenib has been tested to treat these people. However, researchers think a combination of drugs might work better. Objective: To test if treatment with a combination of encorafenib and binimetinib in BRAF mutant HCL is more effective than treatment with vemurafenib. Eligibility: People ages 18 and older with BRAF mutant HCL that did not respond to or came back after treatment Design: Participants will be screened with: Medical history Physical exam Bone marrow biopsy: A needle will be injected through the participant s skin and into a bone to remove liquid. Blood and urine tests Heart and lung function tests CT or MRI scan: Participants will lie in a machine that takes pictures of the body. They may have a contrast agent injected into a vein. Eye exam Participants will take the study drugs by mouth in 28-day cycles. They will take encorafenib daily. They will take binimetinib twice daily. They will keep a pill diary. Participants will take their temperature daily. Participants will have at least 1 visit before each cycle. Visits will include repeats of some screening tests. They will also include abdominal ultrasounds, exercise stress tests, and skin evaluations. Participants may continue treatment as long as their disease does not get worse and they do not have bad side effects. About a month after their last dose of treatment, participants will have a follow-up visit. Then they will have annual follow-ups....
Background: Hairy cell leukemia (HCL) is a rare, slow-growing blood cancer in which the bone marrow makes too many of certain white blood cells. The antibody Rituximab/Ruxience binds to a protein in cancerous white blood cells and is often used to treat HCL. Researchers want to see if combining it with the drug Moxetumomab pasudotox-tdfk (also called Lumoxiti) can fight HCL better. Objective: To test the safety of Moxetumomab pasudotox taken with Rituximab/Ruxience for people with HCL or HCL variant. Eligibility: People age 18 years and older with HCL or HCL variant that has not responded to standard therapy Design: Participants will be screened with: Medical history Physical exam Blood, heart, and urine tests Test of blood oxygen levels Review of bone marrow. This can be from previous test results or a new sample. Scans Exercise test Participants will get the study drugs in up to 8 cycles. A cycle will last about 28 days. The study drugs will be given through a plastic tube in a vein. In the first week of cycle 1, participants will have: 1 visit to get Rituximab or Ruxience for 7.5 hours 3 visits to get Lumoxiti for 30 minutes per infusion In the first week of cycles 2-8, participants will have: 1. visit to get Rituximab/Ruxience for 2-4 hours and Lumoxiti for 30 minutes 2. visits to get Lumoxiti for 30 minutes per infusion Participants will be asked to drink lots of water and take aspirin during the cycles. They will get drugs to minimize allergic reactions. Participants will repeat screening tests at visits throughout the cycles and 1 follow-up visit. They may have an eye exam. ...
BL22 is a type of protein that scientists have created to interact with certain cancer cells. Experiments have shown that BL22 can bind with cancer cells that have a particular kind of protein (called CD22 ) on their surface, and can kill those cells. CD22 is present on certain types of hairy cell leukemia (HCL) cancer cells, and researchers have been working on treatments that will use BL22 and other related proteins to interact with and kill these kinds of cancer cells. The primary purpose of this study will be to provide access to and treatment with BL22 for patients who have HCL in order to determine their response to the treatment. In addition, the study will assess potential side effects of BL22 and examine why some patients respond better than others to treatment with BL22 and related therapies. This study will include about 21 to 25 adults who have been diagnosed with forms of HCL that have not responded well to standard treatments such as surgery, chemotherapy, or radiation therapy. These adults also will have received anti-CD22 therapies before, potentially including treatments with BL22, and have not developed immunity or resistance to these treatments. Prior to the study, patients will undergo a 1- to 2-week screening period to assess their eligibility for treatment. Eligible patients will participate in the study for up to 16 cycles of treatment, with each cycle lasting approximately 4 weeks. For each cycle, patients will receive 1 prescribed dose of BL22 every other day for a total of 3 doses per cycle, and will be assessed after every cycle to evaluate the success of the treatment. During the evaluation visits, patients will be required to have a brief physical examination, give blood and urine samples for testing, and undergo other tests as need to check heart and kidney function and assess the state of the leukemia. Patients who agree will give additional blood, urine, or bone marrow samples for future research purposes.
RATIONALE: The CAT-8015 immunotoxin can bind tumor cells and kill them without harming normal cells. This may be an effective treatment for hairy cell leukemia(HCL) that has not responded to chemotherapy, surgery or radiation therapy. PURPOSE: Phase I dose escalation study to determine the maximum tolerated dose of CAT-8015 immunotoxin in treating patients who have hairy cell leukemia (HCL) that has not responded to treatment.
Background: * About 80% of patients with hairy cell leukemia (HCL) have tumor cells that have a protein on their surface called cluster of differentiation 25 (CD25). * The experimental drug LMB-2 is a recombinant immunotoxin that has been shown to kill leukemia and lymphoma cells with the CD25 protein. (A recombinant immunotoxin is a genetically engineered drug that has two parts - a protein that binds or targets a cancer cell, and a toxin that kills the cancer cell to which it binds.) Objectives: * To evaluate the safety and effectiveness of LMB-2 in patients with HCL whose cancer cells contain the CD25 protein. * To evaluate the effects of LMB-2 on the immune system, determine how the drug is metabolized by the body and examine its side effects. Eligibility: -Adults with hairy cell leukemia whose tumor cells have CD25 on their surface Design: * Up to 27 patients may be included in the study. * Patients receive an infusion of LMB-2 through a vein every other day for three doses (days 1, 3, 5), constituting one treatment cycle. * Patients may receive up to six treatment cycles every 4 weeks unless their cancer worsens or they develop unacceptable side effects. * Blood is drawn weekly for various tests. * Before each cycle and in follow-up visits, disease status is evaluated with a physical examination, blood tests, chest x-ray and electrocardiogram. * Before the first cycle, patients may have a computed tomography (CT) scan, echocardiogram (heart ultrasound test) and bone marrow biopsy. With the patient's permission, these tests may be repeated before other cycles also.
