Filter by:This research study combines 2 different ways of fighting disease: antibodies and T cells. Both antibodies and T cells have been used to treat patients with cancers, and both have shown promise, but neither alone has been sufficient to cure most patients. This study combines both T cells and antibodies to create a more effective treatment. The treatment being researched is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD19 antigen (ATLCAR.CD19) administration. Prior studies have shown that a new gene can be put into T cells and will increase their ability to recognize and kill cancer cells. The new gene that is put in the T cells in this study makes a piece of an antibody called anti-CD19. This antibody sticks to leukemia cells because they have a substance on the outside of the cells called CD19. For this study, the anti-CD19 antibody has been changed so that instead of floating free in the blood part of it is now joined to the T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD19 chimeric (combination) receptor-activated T cells seem to kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown. Preliminary results have shown that subjects receiving this treatment have experienced unwanted side effects including cytokine release syndrome and neurotoxicity. In this study, to help reduce cytokine release syndrome and/or neurotoxicity symptoms, the ATLCAR.CD19 cells have a safety switch that, when active, can cause the cells to become dormant. These modified ATLCAR.CD19 cells with the safety switch are referred to as iC9-CAR19 cells. If the subject experiences moderate to severe cytokine release syndrome and or neurotoxicity as a result of being given iC9-CAR19 cells, the subject can be given a dose of a second study drug, AP1903, if standard interventions fail to alleviate the symptoms of cytokine release syndrome and/or neurotoxicity. AP1903 activates the iC9-CAR19 safety switch, reducing the number of the iC9-CAR19 cells in the blood. The ultimate goal is to determine what dose of AP1903 can be given that reduces the severity of the cytokine release syndrome and/or neurotoxicity, but still allows the remaining iC9-CAR19 cells to effectively fight the lymphoma. The primary purpose of this study is to determine whether receiving iC9-CAR19 cells is safe and tolerable in patients with relapsed/refractory B-cell lymphoma, primary central nervous system lymphoma and chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL).

The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are proteins that protect the body from disease caused by bacteria or toxic substances. Antibodies work by binding those bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected. Both antibodies and T cells have been used to treat subjects with cancers. They both have shown promise, but neither alone has been sufficient to cure most subjects. This study is designed to combine both T cells and antibodies to create a more effective treatment. The treatment that is being researched is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD138 antigen (CAR138 T cells). In previous studies, it has been shown that a new gene can be put into T cells that will increase their ability to recognize and kill cancer cells. A gene is a unit of DNA. Genes make up the chemical structure carrying the subject's genetic information that may determine human characteristics (i.e., eye color, height and sex). The new gene that is put in the T cells in this study makes a piece of an antibody called anti-CD138. This antibody floats around in the blood and can detect and stick to cancer cells called multiple myeloma cells because they have a substance on the outside of the cells called CD138. Anti-CD138 antibodies have been used to treat people with multiple myeloma, but have not been strong enough to cure most subjects. For this study, the anti-CD138 antibody has been changed so that instead of floating free in the blood part of it is now joined to the T cells. Only the part of the antibody that sticks to the multiple myeloma cells is attached to the T cells instead of the entire antibody. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD138 chimeric (combination) receptor-activated T cells seem to kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown.
Background: Blood stem cells in the bone marrow make all the cells to normally defend a body against disease. Allogeneic blood or marrow transplant is when these stem cells are transferred from one person to another. Researchers think this treatment can provide a new, healthy immune system to correct T-cell problems in some people. Objective: To see if allogeneic blood or bone marrow transplant is safe and effective in treating people with T-cell problems. Eligibility: Donors: Healthy people ages 4 and older Recipients: People the same age with abnormal T-cell function causing health problems Design: All participants will be screened with: - Medical history - Physical exam - Blood, heart, and urine tests Donors will also have an electrocardiogram and chest x-ray. They may have veins tested or a pre-anesthesia test. Recipients will also have lung tests. Some participants will have scans and/or bone marrow collected by needle in the hip bones. Donors will learn about medicines and activities to avoid and repeat some screening tests. Some donors will stay in the hospital overnight and have bone marrow collected with anesthesia. Other donors will get shots for several days to stimulate cells. They will have blood removed by plastic tube (IV) in an arm vein. A machine will remove stem cells and return the rest of the blood to the other arm. Recipients will have: - More bone marrow and a small fragment of bone removed - Dental, diet, and social worker consultations - Scans - Chemotherapy and antibody therapy for 2 weeks - Catheter inserted in a chest or neck vein to receive donor stem cells - A hospital stay for several weeks with more medicines and procedures - Multiple follow-up visits
B7451014 is a Phase 3 study to investigate PF-04965842 in patients aged 12 years and over with a minimum body weight of 40 kg who have moderate to severe atopic dermatitis. Subjects responding well to an initial open-label 12 week treatment of PF-04965842 (200 mg) taken orally once daily (QD) will be identified and randomized in a double-blind manner to receive 200 mg QD PF-04965842, 100 mg QD PF-04965842, or QD placebo. Efficacy and safety of 2 doses of PF-04965842 will be evaluated relative to placebo over 40 weeks. Subjects experiencing significant worsening of their symptoms, i.e., protocol-defined flare, enter 12 weeks rescue treatment and receive 200 mg PF-04965842 together with a marketed topical medicine. Eligible patients will have the option to enter a long-term extension study after completing the initial 12 week treatment, the 12 week rescue treatment, and the 40 week blinded treatment.
The body has different ways of fighting infection and disease. No single way is perfect for fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are proteins that protect the body from disease caused by bacteria or toxic substances. Antibodies work by binding bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected with bacteria or viruses. Both antibodies and T cells have been used to treat patients with cancers. They both have shown promise, but neither alone has been sufficient to treat cancer. This study will combine both T cells and antibodies in order to create a more effective treatment called Autologous T Lymphocyte Chimeric Antigen Receptor cells targeted against the CD30 antigen (ATLCAR.CD30). Another treatment being tested includes the Autologous T Lymphocyte Chimeric Antigen Receptor cells targeted against the CD30 antigen with CCR4 (ATLCAR.CD30.CCR4) to help the cells move to regions in the patient's body where the cancer is present. Participants in this study will receive either ATLCAR.CD30.CCR4 cells alone or will receive ATLCAR.CD30.CCR4 cells combined with ATLCAR.CD30 cells. Previous studies have shown that a new gene can be put into T cells that will increase their ability to recognize and kill cancer cells. The new gene that is put in the T cells in this study makes an antibody called anti-CD30. This antibody sticks to lymphoma cells because of a substance on the outside of the cells called CD30. Anti-CD30 antibodies have been used to treat people with lymphoma but have not been strong enough to cure most patients. For this study, the anti-CD30 antibody has been changed so instead of floating free in the blood it is now joined to the T cells. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD30 chimeric (combination) receptor-activated T cells (ATLCAR.CD30) can kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown. Researchers are working to identify ways to improve the ability of ATLCAR.CD30 to destroy tumor cells. T cells naturally produce a protein called CCR4 which functions as a navigation system directing T cells toward tumor cells specifically. In this study, researchers will also genetically modify ATLCAR.CD30 cells to produce more CCR4 proteins and they will be called ATLCAR.CD30.CCR4. The study team believes that the ATLCAR.CD30.CCR4 cells will be guided directly toward the tumor cells based on their navigation system. In addition, the study team believes the majority of ATLCAR.CD30 cells will also be guided directly toward tumor cells when given together with ATLCAR.CD30.CCR4, increasing their anti-cancer fighting ability. This is the first time ATLCAR>CD30.CCR4 cells or combination of ATLCAR.CD30.CCR4 and ATLCAR.CD30 cells are used to treat lymphoma. The purpose of this study to determine the following: - What is the safe dose of ATLCAR.CD30.CCR4 cells to give to patients - What is the safe dose of the combination of ATLCAR.CD30 and ATLCAR.CD30.CCR4 cells to give to patients

Both antibodies and T cells have been used to treat patients with cancers, and both have shown promise, but neither alone has been sufficient to cure most patients. This protocol combines both T cells and antibodies to create a more effective treatment.

The primary purpose of this protocol is to treat a single patient with a second dose of iC9-CAR19 T cells.

Atopic Dermatitis (AD), also known as eczema, is a common skin disease characterized by itchy lesions. The prevalence of AD has increased over the past few decades, with 15-30% of children and 2-10%of adults being affected. The lesions of AD patients are very inflamed, with an increased number of inflammatory cells in the skin. There are not many medications available that are fully effective and can be used long-term for treatment of atopic dermatitis. Benralizumab is a monoclonal antibody used for treatment of a type of asthma called "eosinophilic asthma". Atopic dermatitis is also associated with elevated levels of eosinophils, and we would like to determine if benralizumab is effective in patients with atopic dermatitis. This is a randomized, double-blind, parallel group, placebo-controlled study will evaluate the effect of 3 doses of a fixed 30 mg dose of benralizumab administered subcutaneously (SC) every 4 weeks to patients with moderate-to-severe atopic dermatitis, on the severity of atopic dermatitis, and the cellular inflammation of skin lesions in these patients. Anti-inflammatory properties of benralizumab when a skin flare is induced in a controlled laboratory setting, in addition to the effects of benralizumab on skin that is already inflamed will be examined.It is hypothesized that benralizumab will attenuate eosinophilic inflammation in the skin.
