Patients with relapsed or refractory T-cell acute lymphoblastic leukemia (r/r T-ALL) have few options and poor prognosis. The aim was to assess donor-derived anti-CD7 chimeric antigen receptor (CAR) safety efficacy in patients r/r T-ALL.In this single-center, phase I trial, we administered CAR T cells, manufactured from either previous stem-cell transplantation donors new donors, T-ALL, single infusions at doses of 5 × 105 1 106 (±30%) cells per kilogram body weight. primary end point...

Abstract Despite worldwide promising clinical outcome of CD19 CAR-T therapy, relapse after this therapy is associated with poor prognosis and has become an urgent problem to be solved. We conducted a CD22 CAR T-cell in 34 relapsed or refractory (r/r) B-ALL pediatric adult patients who failed from previous therapy. Complete remission (CR) CR incomplete count recovery (CRi) was achieved 24 30 (80%) that could evaluated on day infusion, which accounted for 70.5% all enrolled patients. Most only...

Abstract Immunotherapy utilizing chimeric antigen receptor T cell (CAR-T) therapy holds promise for hematologic malignancies, however, response rates and associated immune-related adverse effects widely vary among patients. Here we show, by comparing diversity composition of the gut microbiome during different CAR-T therapeutic phases in clinical trial ChiCTR1800017404, that flora characteristically differs patients according to treatment stages, might also reflect patient...

Abstract Chimeric antigen receptor-T (CAR-T) therapy remains to be investigated in T-cell malignancies. CD7 is an ideal target for malignancies but also expressed on normal T cells, which may cause CAR-T cell fratricide. Donor-derived anti-CD7 cells using endoplasmic reticulum retention have shown efficacy patients with acute lymphoblastic leukemia (ALL). Here we launched a phase I trial explore differences between autologous and allogeneic therapies ALL lymphoma. Ten were treated 5 received...

CD19-targeting chimeric antigen receptor (CAR)-T cell therapy has shown great efficacy in patients with relapsed/refractory non-Hodgkin lymphoma (NHL) but been associated serious adverse effects, such as cytokine release syndrome (CRS). It speculated that NHL baseline disease burden might affect clinical outcome and CRS, this not explored detail any previous study.

Abstract The prognosis of relapsed acute lymphoblastic leukemia (ALL) after allogeneic transplantation is dismal when treated with conventional approaches. While single‐target CD19 or CD22 chimeric antigen receptor (CAR) T‐cell therapy has achieved high complete remission (CR) rates in refractory/relapsed B‐ALL, it could not maintain a durable most patients. To prolong relapse‐free survival, we sequentially combined and CAR‐T cells to treat post‐transplant B‐ALL patients both CD19/CD22...

Abstract Background Consolidative allogeneic hematopoietic stem cell transplantation is a controversial option for patients with relapsed/refractory acute lymphoblastic leukemia after chimeric antigen receptor T (CAR-T) therapy. We performed multicenter retrospective study to assess whether can benefit from haploidentical CAR-T Methods A total of 122 therapy were enrolled, including 67 without subsequent (non-transplant group) and 55 (transplant group). Long-term outcome was assessed, as its...

Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity are two major CAR T related toxicities. With the interventions of Tocilizumab steroids, many patients can recover from severe CRS. However, some refractory to steroids develop life-threatening consequences. Ruxolitinib is an oral JAKs inhibitor promising drug in inflammatory diseases. In this pilot study, we evaluate efficacy Of 14 r/r B-ALL children who received CD19 or CD22 cell therapies, 4 developed (≥grade...

Chimeric antigen receptor (CAR) T-cell therapies that target either CD19 or CD22 alone have potent antilymphoma effects. However, escape-mediated relapse often occurs. CAR T cells targeting both and may overcome this limitation. In study, we developed bispecific simultaneously recognizing CD19- CD22-expressing targets assessed their safety efficacy profiles in patients with relapsed/refractory aggressive B-cell lymphoma. Twenty-four were screened, 16 found eligible for the study....

Erythropoietin-producing hepatocellular carcinoma A2 (EphA2) is overexpressed in more than 90% of non-small cell lung cancer (NSCLC) but not significantly normal tissue. It therefore an important tumor antigen target for chimeric receptors (CAR)-T-based therapy NSCLC. Here, we developed a specific CAR targeted to EphA2, and the anti-tumor effects this were investigated. A second generation with co-stimulatory receptor 4-1BB EphA2 was developed. The functionality EphA2-specific T cells vitro...

Background Murine chimeric antigen receptor T (CAR-T) cell therapy has demonstrated clinical benefit in patients with relapsed/refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL). However, the potential immunogenicity of murine single-chain variable fragment domain may limit persistence CAR-T cell, leading to relapse. Methods We performed a trial determine safety and efficacy autologous allogeneic humanized CD19-targeted (hCART19) for R/R B-ALL. Fifty-eight (aged 13–74 years) were...

Metastatic castration‐resistant prostate cancer (mCRPC) is a heterogeneous disease. Several studies have identified transcriptional subtypes of mCRPC, but comprehensive analysis prognostic gene expression pathways has been limited. Therefore, we aggregated cohort 1012 mCRPC tissue samples from 769 patients and investigated the association expression‐based with clinical outcomes intrapatient intratumor heterogeneity. Survival data were obtained for 272 patients. Pathway‐level enrichment was...
