Filter by:In light of the current coronavirus disease 2019 (COVID-19) pandemic, the investigators want to better study the immunological characteristics of Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV2) infections in adults. The investigators invite volunteers to participate in a clinical study to better understand what happens after an infection with SARS-CoV2. By collecting and analysing blood samples of people that were infected, the investigators want to evaluate whether or not the participants had an adaptive immune response with the producting of immunoglobulin. The investigators will evaluate the quality of the antibodies and their neutralising capacity. In a selected patient group with strong antibody response, the investigators will try to reproduce them in the lab after the collection of a larger blood sample (max 72 mL) of, in case of insufficient B-cells, a leucapheresis (after consent of the patient). These antibodies can be used in clinical trials to evaluate whether the investigators can cure patients faster or prevent disease by the utilisation of these antibodies. Aside from the aforementioned information the investigators will also collect clinical data such as: demographic information, medical history, routine lab results, radiographic imaging and medication use. After the completion of the study, the samples will be stored for 30 years with consent of the participants.
New York City (NYC) has become the epicenter of the worldwide pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). By collecting and summarizing the experience with other major health care providers in the tristate (New York (NY), New Jersey (NJ) and Connecticut (CT)) are, the investigators are uniquely positioned to inform the rest of the country about what to expect and how to manage children and young adults with hematological, oncological or stem cell transplant diagnoses during the pandemic.
SARS-CoV-2 outbreak causes a spectrum of clinical patterns that varies from asymptomatic infection to mildly symptomatic manifestations and more-severe forms that need intensive care. Until now, the immune response to SARS-CoV-2 virus infection has been poorly reported to help decision for immune modulation therapies. As a consequence, trials have been designed to test both anti-inflammatory molecules as steroids or anti-bodies against IL-6, and others proposing to "boost" immunity with interferon beta based on similar inclusion criteria. The immune response to infective agents including viruses may have a complex time evolution with early and late phases corresponding to different patterns, oscillating between pro-inflammation and immune-depression. The potential window to improve outcome in COVID-19 by therapeutic intervention aimed at a fine tuning between immune toxicity and immunodepression requires a longitudinal assessment during the course of illness, especially for the patients who develop acute respiratory failure. Immune monitoring of both innate and adaptive immunity would then be essential to appropriately design clinical trials. The whole blood cells evaluation was recorded according to the time intervals between the onset of symptoms and the sampling after ICU admission. Patients' care was standardized, especially with regard to ventilation, sedation, and antimicrobial treatment. In this study the investigators prospectively perform a longitudinal study of both innate and adaptive immunity on patients admitted to ICU for an COVID-19 related acute respiratory failure. The data will be analyzed in reference to the onset of initial symptoms and also to the admission in ICU. The primary end point is the evolution of the characterization of monocytes and their subsets in term of number and expression of HLA-DR. A similar approach is used for lymphocytes and their subtypes with in addition, an ex vivo testing of their capabilities to be stimulated by SARS-CoV-2 viral proteins in term of TNFalpha, INFgamma, and IL1beta production. The secondary end-point was to test the association with outcomes and other non-specific markers of inflammation as CRP (C reactive protein), PCT (procalcitonin), DDimers and ferritin.
This is an open-label, multicenter, Phase 2 study to determine the safety, PK, and efficacy of lisocabtagene maraleucel (JCAR017) in subjects who have relapsed from, or are refractory to, two lines of immunochemotherapy for aggressive B-cell non-Hodgkin lymphoma (NHL) in the outpatient setting. Subjects will receive treatment with JCAR017 and will be followed for up to 2 years.
The investigators aim to evaluate the roles of Th17/Treg cells and IL-23/IL-17 axis in the mechanisms of early enteral nutrition (EEN) correcting immune imbalance of sepsis by means of improving the intestinal flora disturbance. The results of this study would lay the foundation for revealing the mechanisms of EEN improving immune imbalance of sepsis and provide a new idea to the early treatment of sepsis
This healthy male volunteers study will evaluate 148 subjects who will receive a single sub-cutaneous dose of HLX03 （a monoclonal antibody against TNF-a, 40 mg/ 0.8 mL） or Adalimumab(Humira,China spourced,40 mg/0.8 mL injection with a single-use prefilled syringe). This study will involve sampling,pharmacokinetics, safety, tolerability and immunogenicity evaluation of drug levels following administration of HLX03 and the licensed adalimumab products.
This pilot clinical trial studies total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients with severe combined immunodeficiency (SCID) undergoing donor bone marrow transplant. Giving total-body irradiation (TBI) before a donor bone marrow transplant using stem cells that closely match the patient's stem cells, helps stop the growth of abnormal cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may mix with the patient's immune cells and help destroy any remaining abnormal cells. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.
