Active clinical trials for "Acute Disease"

Patients with active acute leukemia have dismal prognoses even with allogeneic transplantation.Thus,new measures to enhance graft versus leukemia effect and reduce relapse rates are needed. Relapse risk after double umbilical cord transplantations have been shown to be significantly lower compared to matched sibling and matched unrelated donor transplantations due to better graft versus leukemia effect. The investigators hypothesize, that concomitant transplantation from 2 matched siblings may improve GVL effect and reduce relapse rate in patients with high risk acute leukemias and other high risk hematological malignancies.

Hypothesis: Add-on therapy with oral montelukast (Mon) to inhaled budesonide (BUD) may achieve better control of cough caused by nonasthmatic eosinophilic bronchitis (NAEB) with faster reduction of airway eosinophilia. Objective: To evaluate the efficacy of add-on therapy with Mon to inhaled corticosteroids (ICS) in the treatment of adult patients with chronic/subacute cough caused by NAEB diagnosed in outpatient setting. Primary endpoint：cough severity rated as cough visual analogue score (VAS)1 and eosinophil count in induced sputum during 4-week BUD monotherapy or Mon adjunct therapy.

A novel method has been developed to expand natural (NK) cells and enhance their cytotoxicity against cancer cells while maintaining low killing capacity against non-transformed cells. In this method, donor NK cells are expanded by co-culture with the irradiated K562 cell line modified to express membrane bound IL-15 and 41BB ligand (K562-mb15-41BBL). Expression of these proteins in conjunction with unknown stimuli provided by K562 cells promotes selective growth of NK cells. Then, the expanded NK cell population is depleted of T cells to prevent graft versus host disease (GVHD). Expanded and activated NK cells showed powerful anti-leukemic activity against acute myeloid leukemia (AML) cells in vitro and in animal models of leukemia.Unpublished laboratory results also demonstrated that T-cell acute lymphoblastic leukaemia (T-ALL) is extremely sensitive to the cytotoxicity exerted by the expanded and activated NK cells. The present study represents the translation of the laboratory findings into clinical application. The study proposes to determine the feasibility, safety and efficacy of infusing expanded NK cells into patients who have AML or T-lineage ALL which is resistant to standard therapy as demonstrated by persistent minimal residual disease (MRD). Patients with myelodysplastic syndrome (MDS), who are at high risk to develop AML will also be eligible for the study. In this patient cohort, the study will also investigate the in vivo lifespan and phenotype of the expanded NK cells. The main hypothesis to be tested in this study is that infusion of expanded activated NK cells can produce measurable clinical responses in patients with AML or T-ALL.

A multicenter,randomized,single-blind, placebo-controlled,phase 4 clinical trial to evaluate the efficacy and safety of andrographolide sulfonate in patients with acute exacerbation of chronic bronchitis

RATIONALE: Giving chemotherapy and total marrow and lymphoid irradiation before allogeneic hematopoietic cell transplant helps stop the growth of leukemia cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may achieve brand new hematopoietic recovery. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells, resulting in graft versus-host disease. PURPOSE: This study is to evaluate the toxicity and efficacy of total marrow and lymphoid irradiation conditioning when given together with combination chemotherapy and allogeneic peripheral blood stem cell transplant in treating patients with high-risk acute leukemia.

The investigators hypothesize that perturbations in the intestinal microbiota following allogeneic hematopoietic stem cell transplantation (HSCT) are essential for the development and propagation of acute graft-versus-host disease. Therefore, modification of HSCT recipients' gut microbiota using fecal transplantation from a healthy donor could be used to treat gut acute GVHD. The study evaluates safety and feasibility of fecal microbiota transplantation with frozen capsules from healthy donors for the treatment of steroid resistant or steroid dependent acute graft-versus-host disease of the gut.

This study is a phase 2, multicentre, dose-finding, double-blind, randomized placebo-controlled trial to evaluate the efficacy and safety of two different doses of GHX02, compared with placebo, for acute bronchitis. One-hundred and fifty patients will be included in this trial and randomly assigned to either a high-dose GHX02 group(1920mg/day), standard-dose GHX02 group(960mg/day), or control group(placebo) in a 1:1:1 allocation ratio. Patients will take one of the medications three times a day for 7 days, with 3 visiting days(screening, day0, day7). On the screening day, the Korean Standard Tool of Pattern Identification of Cough and Sputum, a diagnostic system that determines therapy in Traditional Korean Medicine, will be used to allocate patients into three groups of wind-heat, wind-cold or others.

A Multicenter, Randomized, Double-Blind, Parallel, Active-controlled, Superiority, Phase III Clinical Trial to Evaluate the Efficacy and Safety of DW1601 Compared to DW16011 and DW16012 for Acute Bronchitis

Any pathogen that causes an upper respiratory tract infection can cause bronchitis.The primary pathogen is virus. On the basis of virus infection, pathogenic bacteria may cause secondary infection or co-infection。Xiyanping injection is mainly used in the treatment of bronchitis by intravenous injection。

There is no confirmed drug therapy for plastic bronchitis. The study wish to test the effectiveness and safety of sirolimus (rapamycin) in patients with lymphatic plastic bronchitis.
