Active clinical trials for "Immune System Diseases"

This phase II pediatric MATCH treatment trial studies how well selpercatinib works in treating patients with solid tumors that may have spread from where they first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), lymphomas, or histiocytic disorders that have activating RET gene alterations. Selpercatinib may block the growth of cancer cells that have specific genetic changes in an important signaling pathway (called the RET pathway) and may reduce tumor size.

The purpose of this study is to evaluate the efficacy of loncastuximab tesirine (ADCT-402) combined with rituximab compared to standard immunochemotherapy.

Philadelphia chromosome (BCR-ABL1, Ph) is the most common genetic abnormality in acute lymphoblastic leukemia (ALL) and an independent prognostic risk factor. With the increase of age, the incidence of patients over 60 years old can reach 50%, whose 5-year overall survival rate was less than 20%. With the application of tyrosine kinase inhibitor (TKI), the prognosis of Ph positive ALL patients is greatly improved. At present, TKI combined with chemotherapy has become the first-line treatment recommended in the guideline of Ph positive ALL patients. However, with the use of imatinib, more and more patients develop drug resistant to imatinib. In addition, the clinical data showed that the MRD negative rate in patients treated with imatinib combined with hyper CVAD was only 22% three months later, which was far lower than 31% of the second generation TKI and 52% of the third generation TKI. Second generation TKI dasatinib and nilotinib can overcome most imatinib resistant kinase region mutations. However, patients with severe hemocytopenia, infection or other complications are often unable to tolerate the standard chemotherapy. In addition, due to the high cost, some patients can't afford the long-term use. Flumatinib is the first approved second generation TKI in China and a derivative of imatinib. Compared with imatinib, it introduced trifluoromethyl, substituted pyridine ring for benzene ring, and kept the direction of amide bond, which made the inhibitory effect of flumatinib on common kinase mutations significantly better than that of imatinib. In addition, compared with the second-generation TKI recommended in the first line of current guidelines, the incidence of quality of life related adverse reactions of flumatinib is lower, and no specific adverse reactions of the second-generation TKI have been reported. We plan to enroll 28 patients with Ph positive ALL. All patients are diagnosed by morphology, immunology, cytogenetics and molecular biology (MICM). According to subjects' age, we will divide them into two groups. Subjects aged 60 years or older are received flumatinib and dose-adjusted VDCP or prednisone regimen. Subjects younger than 60 years are received flumatinib and hyper-CVAD regimen. MRD are examined on the 8th, 15th and 29th day after chemotherapy. Then, MRD will be monitored in the third, 6th, 9th, 12th, 15th, 18th, 21th and 24th months after chemotherapy to evaluate the effect.

The potency of immune checkpoint blockade is limited in most solid malignancies, one possible reason for which is tumor microenvironment. Enhancer of zeste homolog 2 (EZH2) as a epigenetic target for cancer therapy has attracted significant interest. The combination of EZH2 inhibitors and programmed death-1 ligands/ transforming growth factor-β (PD-L1/TGFβ) blockade may enhance the efficiency of immunotherapy.The primary objective of this study in phase Ⅰstage is to assess the safety, feasibility of EZH2 inhibitor SHR2554 in combination with anti-PD-L1/TGFβ antibody SHR1701 in advanced pretreated solid tumors and b-cell lymphomas. The phase Ⅱ stage of this study is to primarily evaluate the efficacy of SHR2554 plus SHR1701 and the epigenetic modulating effect of SHR2554.

This study is an exploratory, randomized, double-blind, multicenter, placebo-controlled study with repeated doses of AP1189. The study population will consist of patients with idiopathic membranous nephropathy (iMN) and severe proteinuria who are on ACE inhibitor or angiotensin II receptor blocker treatment.

The French Public Health Council recommended pneumococcal vaccination combined strategy for all immunocompromised patients in 2012. This strategy consisted in conjugated 13-valent pneumococcal injection followed 2 months later by polysaccharide 23-valent vaccine injection. General practitioners are usually in charge of this vaccination. Conjugated pneumococcal vaccine enhances the immunogenicity of the polysaccharide vaccine. Acute leukemia and lymphoma are treated with multiple courses of chemotherapy, impairing the immune system and potentially the response to vaccination. These patients are more at risk for developing pneumococcal invasive diseases than the general population. However, efficacy of pneumococcal vaccination is poorly documented in this setting. We assume that 70% of the patients are non-responders to vaccination, according to their anti-pneumococcal immunoglobulin G titers and the opsonophagocytic activity. To assess the immunogenicity of the pneumococcal vaccination combined strategy in adult population of acute leukemia and lymphoma, the investigator will measure anti-pneumococcal serotype-specific immunoglobulin G titers and opsonophagocytic activity at different time-points after completion of the combined vaccine strategy. The primary objective is to assess the immunogenicity of pneumococcal vaccination combined strategy at 3 months after the 13-valent pneumococcal injection (corresponding to 1 month after the end of the combined strategy) using immunoglobulin G titers and opsonophagocytic activity. At different time points (day 0, 1 month after the 13-valent pneumococcal injection, the day of the injection of the polysaccharide 23-valent vaccine, one month after the injection of the polysaccharide 23-valent vaccine, 3-6 months after the polysaccharide 23-valent vaccine,9-12 months after the polysaccharide 23-valent vaccine), the immunological response to vaccination will be monitored using specific-serotype immunoglobulin G titers, opsonophagocytic activity, and total anti-pneumococcal Immunoglobulin. The investigator will determine predictive factors of non-response to vaccination by comparing demographic data, biological data and treatment received by both acute myeloblastic leukemia and lymphoma patients. The tolerance and safety of the vaccination strategy will also be assessed in this specific hematological population.

This is a single arm, open-label, single-center, phase I/II study to determine the safety and efficacy of CD19 CAR-T( ssCART-19) combined with feeding T cells (FTCs) as consolidation therapy in patients diagnosed with de novo Philadelphia chromosome positive CD19+ B-ALL. The study will contain the following sequential phases: screening, lymphocyte apheresis, induction and consolidation chemotherapies combined with tyrosine kinase inhibitors. Once in complete response, patients will receive four cycles of ssCART-19s, namely one cycle of ssCART-19 infusion followed by another three cycles of ssCART-19 and FTC infusion. The role of FTCs is to mimic leukemia cells. Therefore, they are expected to stimulate in vivo expansion and persistence of ssCART-19. Considering the limited number of lymphocytes obtained by a single apheresis from patients and cost-efficacy, in addition to safety, we will explore the range of biologically active doses of FTCs in a phase I study. Based on preclinical data, FTCs stimulation of ssCART-19 at a ratio of 1:1 could achieve the best activation response, so 5×106/kg dosage of FTCs was set as the initial dosage in the study, and lower dose was also evaluated. In this study, FTCs will be administered at the dose of 5×106/kg, 3.25×106/kg or 2×106/kg two hours after ssCART-19 infusion on day 1 and once again administered at the same dose on day 8. After ssCART-19 and FTCs infusion, efficacy will be assessed by detecting molecular response for 6 months, PFS and OS will be followed up for 2 years. In phase II, we will expand the study at optimal biological doses of FTCs, and further evaluate the efficacy and safety of the innovative combination therapy of CD19 CAR-T and FTCs.

This Phase 1 Study is an open-label, non-randomized, dose escalation, safety, efficacy, pharmacokinetic, and pharmacodynamic evaluation study of INA03 administered as a single agent IV infusion every 2 weeks to patients ≥18 years of age with R/R AML, MLL, or ALL. The study will be performed in 2 parts: a Dose Titration for Day 1 study (Part 1) followed by a Dose Escalation Part (Part 2) of INA03 used as monotherapy.

This phase II trial investigates two strategies and how well they work for the reduction of graft versus host disease in patients with acute leukemia or MDS in remission. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer 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 help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells.

The trial will investigate the combination of venetoclax, obinutuzumab and lenalidomide in patients with treatment-naïve follicular lymphoma. Patients will receive induction treatment for 0.5 years with venetoclax, obinutuzumab and lenalidomide followed by maintenance treatment for upto 2 years. Maintenance treatment will be determined by the response at the end of induction. Following completion of treatment patients will be followed up for 3 years after the last patient completes induction treatment.
