Acute Graft Versus Host Disease

To observe the effect of stem cell infusion on the development of acute graft- versus-host disease (aGVHD) in patients with nonmalignant hematologic diseases after allogeneic peripheral blood hematopoietic stem cell transplantation (allo-PBSCT)

This clinical trial evaluates the feasibility and effectiveness of a post-transplant dental cleaning for the prevention of chronic graft versus host disease (GVHD) in patients undergoing an allogeneic hematopoietic cell transplant (HCT). HCT is the only curative treatment for some types of blood cancer. Unfortunately, this approach can lead to the development of GVHD, which is a disease caused when cells from a donated stem cell graft attack the normal tissue of the transplant patient. Some research has shown that the bacteria that is present in the dental plaque soon after transplant may affect the development of chronic GVHD. Dental cleanings prior to transplant are part of the normal standard of care for patients undergoing HCT. Adding an additional cleaning shortly after HCT may be effective for preventing the development of chronic GVHD.

This phase I trial tests the safety and side effects of leflunomide in combination with steroids in treating patients with acute graft versus host disease who have undergone done stem cell transplant for blood cancers (hematologic malignancies). Sometimes the transplanted cells from a donor can attack the body's normal cells (called graft-versus-host disease). Leflunomide and steroids are immunosuppressive drugs that work in different ways to lower the body's immune response so that the new donor immune cells do not attack the body's normal cells. Giving leflunomide in combination with steroids may help treat acute graft versus host disease in patients after stem cell transplant for hematologic malignancies.

With the stem cell transplanting increasing, patients which effected with gut GVHD were also increased. To evaluation the safety and efficacy of FMT for gut GVHD,patients with gut GVHD were recruited.

This study is a prospective, multicenter, open-label, phase II clinical trial designed to evaluate the safety and efficacy of moxibustion in patients with steroid-refractory acute graft-versus-host disease (SR-aGVHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT). A total of 42 patients with SR-aGVHD, primarily involving the gastrointestinal tract and presenting with abdominal pain and diarrhea, will be enrolled. All participants will receive standard second-line therapy based on best available treatment (BAT), including ruxolitinib, basiliximab, or methotrexate, according to clinical judgment. In addition, patients will receive moxibustion at specific acupoints (Tianshu \[ST25\], Shenque \[CV8\], and Qihai \[CV6\]) for 30 minutes once or twice daily for 28 days. The primary endpoint is the overall response rate (ORR) at Day 28. Secondary endpoints include durable ORR at Day 56, incidence and severity of chronic GVHD (cGVHD), non-relapse mortality (NRM), overall survival (OS), and changes in traditional Chinese medicine (TCM) syndrome scores. Safety will be assessed by monitoring adverse events throughout the study period. This study aims to explore whether moxibustion, as an adjunctive therapy, can improve clinical outcomes and provide a safe and effective treatment strategy for patients with SR-aGVHD after allo-HSCT.

This clinical trial will study ruxolitinib-based treatment of acute graft-versus-host-disease (GVHD) that developed following allogeneic hematopoietic cell transplant. Acute GVHD occurs when donor cells attack the healthy tissue of the body. The most common symptoms are skin rash, jaundice, nausea, vomiting, and/or diarrhea. The standard treatment for GVHD is high dose steroids such as prednisone or methylprednisolone, which suppresses the donor cells, but sometimes there can be either no response or the response does not last. In these cases, the GVHD can become dangerous or even life threatening. High dose steroid treatment can also cause serious complications. Researchers have developed a system, called the Minnesota risk system, to help predict how well the GVHD will respond to steroids based on the symptoms present at the time of diagnosis. The Minnesota risk system classifies patients with newly diagnosed acute GVHD into two groups with highly different responses to standard steroid treatment and long-term outcomes. This protocol maximizes efficiency because all patients with grade II-IV GVHD are eligible for screening and treatment is assigned according to patient risk. Patients with lower risk GVHD, Minnesota standard risk, have high response rates to steroid treatment. In this trial the researchers will test whether ruxolitinib alone is as effective (non-inferior) as steroid-free therapy and safe. Patients will be randomized to two different doses of ruxolitinib to identify the dose which maximizes efficacy while minimizing toxicities such as hematologic and infectious toxicities. Patients with higher risk GVHD, Minnesota high risk, have unacceptable outcomes with systemic corticosteroid treatment alone and the researchers will test whether adding ruxolitinib, a proven effective second line GVHD treatment, can improve outcomes when added to systemic corticosteroids as first line treatment.

The study was an open-label, single-arm, dose-escalation, Phase Ib, multi-center study to investigate safety, pharmacokinetics, pharmacodynamics and preliminary efficacy of AC-003 in patients with grade II-IV SR-aGVHD.

This study is about determining if an aerobic and resistance exercise intervention is feasible in patients diagnosed with acute or chronic GVHD (Graft-Versus-Host Disease) after having an allogeneic stem cell transplant. The names of the study interventions involved in this study are: * Aerobic and resistance exercise (A+R) - Home-based aerobic and resistance exercise program * Attention control (AC) - Home-based stretching program

Graft-versus-host disease is a complication of allogeneic hematopoietic cell transplantation with high morbidity and mortality. The standard treatment is corticosteroids, and based on the response within 3 to 7 days, a second-line therapy is added, which is expensive and not easily accessible. The administration of human chorionic gonadotropin has shown therapeutic effectiveness in 50% of patients in reported clinical cases.
