Filter by:In this phase I single-arm clinical study, 20 patients with T4b unresectable locally advanced colon cancer are proposed to be enrolled, who will be treated with MR-Linac with short course radiotherapy (25Gy/5F), followed by 4 cycles of mFOLFOX6 or 3 cycles of XELOX chemotherapy, then radical surgical resection, and then postoperatively with 8 cycles of mFOLFOX6 or 5 cycles of XELOX. The study will assess patients' surgical R0 resection rate, pCR or cCR rate, PFS, OS, and related adverse effects of treatment, aiming to explore the feasibility, safety, and efficacy of MR-Linac in the treatment of unresectable locally advanced colon cancer.
Acute graft-versus-host disease (aGVHD) is the most common life-threatening complication of allogeneic hematopoietic stem cell transplantation. The investigators try to observe the efficacy and safety of application of vedolizumab, anti-CD25 monoclonal antibody and rapid reduction of glucocorticoids in the treatment of grade 3-4 steroid-refractory aGVHD(SR-aGVHD) with lower gastrointestinal involvement.

SBRT (stereotactic radiotherapy) can provide a higher dose to the target area without increasing the risk of surrounding normal tissue / organ injury in selective cases. At present, SBRT has been widely used in radiotherapy of lung cancer and it can also play a better local control for lung metastasis. However, there are parallel organs and series organs in the chest, and different organs have different tolerance to radiotherapy, so the toxicities of SBRT in different sites are different, and the prescription dose is also different. This study intends to make a detailed division of the chest region and explore the safety and efficacy of SBRT in different areas. It is divided into four types: chest wall type: the lesion is directly adjacent or overlapped with the chest wall; peripheral type: the lesion is more than 1cm away from the chest wall and more than 2cm away from the bronchial tree; central type: the lesion is less than 2cm away from the bronchial tree; ultral-central type: the lesion is directly adjacent or overlapped with the mediastinal structure. 48-60Gy / 4-10f (EQD2 = 62.5Gy ~ 99.7Gy) was given according to the location of the tumor. Main outcome measures are local progression free survival and radiation toxicities; secondary outcome measure is overall survival.
This trial will explore the maximum tolerated dose of cord blood NKG2D CAR-NK in the treatment of recurrent refractory acute myeloid leukemia in a dose-escalation manner, and observe its clinical safety and efficacy.
Allogeneic hematopoietic stem cell transplantation (Allo-HSCT) is one of the most important and effective methods for the treatment of hematologic malignancies.Chronic graft-versus-host disease (cGVHD) is a serious complication of allogeneic stem cell transplantation with few effective options available after failure of corticosteroids. It is a leading cause of late nonrelapse mortality for transplant patients, also contributing to morbidity and a decrease in quality of life.Corticosteroids, the standard frontline treatment, are typically administered for a median of 2 to 3 years, leading to substantial morbidity. An effort to decrease corticosteroid doses has led to their use in combination with other immunosuppressants, such as cyclosporine, tacrolimus, and sirolimus, in frontlineor second-line settings, despite a lack of clinical evidence supporting additional efficacy after combining these agents with corticosteroids. B and T cells play a rolein the pathophysiology of cGVHD. Previous studies have shown that low-dose histone deacetylase inhibitors (HDACi) have a negative immune regulation in GVHD while maintain the GVL effect. Chidamide is one of new HDACis in China, the previous studies suggested that low dose Chidamide could reduce condition of cGVHD mice by regulating the immune homeostasis of follicular helper T (Tfh) cells. Chidamide also has effects on the regulation of antigen presenting cells, the activation donor T cells, the release of proinflammatory cytokines and the function of Treg cells. Furthermore, low-dose Chidamide has the potential to maintain GVL effects. In preclinical models,Chidamide reduced severity of cGVHD. Based on the biological rationale and preclinical data, a study was designed to evaluate the safety and efficacy of Chidamide in patients with cGVHD who was steroid-resistant/steroid-dependent .
Acute graft-versus-host disease (aGVHD) is the most common life-threatening complication of allogeneic hematopoietic stem cell transplantation. The recognized first-line treatment for grade 3-4 aGVHD is systemic glucocorticoid. However, there is no recognized second-line treatment for grade 3-4 steroid-resistant aGVHD (SR-aGVHD). The investigators try to observe the efficacy and safety of early application of anti-CD25 monoclonal antibody(basiliximab) combined with ruxotilinib in the treatment of severe SR-aGVHD.
ENKTL is a highly aggressive non-Hodgkin lymphoma closely related to EBV infection，and advanced patients often suffer from hemophagocytic lymphohistiocytosis (HLH). ENKTL-HLH lacks standard treatment and experiences a extremely poor prognosis. Anti-PD-1 antibody has shown good anti-tumor activity in ENKTL and play a potential role in EBV-HLH. Epigenetic drugs have been confirmed to exert synergistic anti-tumor activity with anti-PD-1 antibody. We next further explore the efficacy and safety of Sintilimab sequential combination of epigenetic drugs in ENKTL-HLH.
ENKTL is a highly aggressive NHL with a higher incidence in Asia. L-asparaginase containing chemotherapy regimens are the standard first-line treatment with apparently toxicities. In 2020 ASH, the investigators reported Sintilimab(anti-PD-1 antibody) plus Chidamide(an oral subtype-selective HDACi) yielded effective antitumor activity, durable response in patients with relapsed or refractory ENKTL(SCENT trial. Abstracts 644). The investigators next conducted a exploratory study to investigated the safety and efficacy of Sintilimab plus Chidamide(SC) for patients with newly diagnosed ENKTL(SCENT-2 trial).
This clinical trial is carried out in two phases. The first phase adopts an open design, and the second phase adopts a randomized, blinded, and similar vaccine-controlled non-inferiority trial design. The first stage: According to the order of two age groups of 18-60 years old and 10-17 years old, 40 cases were enrolled in each age group (20 persons for the 5-dose program and 20 for the 4-dose program). Subjects in the 5-dose group received 1 dose of test vaccine on 0, 3, 7, 14, and 28 days each. Subjects in the 4-dose group received 1 dose each on both arms on day 0, and 1 dose on day 7 and day 21 each. All subjects in the first stage were only observed for safety and were followed up to 6 months after the entire course of vaccination. The second stage: the total number of enrolled 2400 cases, 10-60 years old, the 4-dose program group and the 5-dose program group of the test vaccine, the 4-dose program group and the 5-dose program group of the control vaccine according to the random ratio 1:1:1:1. Among the total number of participants, 1680 cases (420 cases per group) were simultaneously observed for immunogenicity and safety, and the remaining 720 subjects (180 cases per group) only underwent safety observation. 800 subjects (200 cases in each group) received 6-month immune persistence observation after full vaccination, and 400 subjects in the test vaccine group received 12 months immune persistence observation after full vaccination. In the second stage, 1680 subjects were collected before the immunization, 7 days after the first dose, 14 days after the first dose, and 14 days after the full vaccination to test rabies virus antibodies to evaluate the immunogenicity of the test vaccine. 800 subjects were in the whole process Immune persistent blood sampling was performed 6 months after vaccination, and subjects in the test vaccine group were further subjected to immune persistent blood sampling 12 months after the full course of vaccination to evaluate immune durability. Collect all AEs within 30 minutes after each dose, AEs from 0-7 days, all non-collective AEs from the first dose to 30 days after the full course of vaccination, and all serious AEs from the first dose to 6 months after the full course of vaccination Adverse events.
