A Phase 1 Study to Evaluate the Efficacy and Safety of AB-101, an Allogeneic Cord Blood- Derived NK-Cell Therapy in Combination With B-Cell Depleting mAb in Patients Who Failed Treatment for Class III or IV Lupus Nephritis
AB-101 (also known as AlloNK) is an off-the shelf, allogeneic cell product made of "natural killer" cells, also called NK cells. White blood cells are part of the immune system and NK cells are a type of white blood cell that is known to enhance the effect of monoclonal antibody therapies. This clinical trial will enroll adult patients with lupus nephritis Class III or IV either with or without the presence of Class V who relapsed or did not respond to previous standard of care treatment approaches. The primary objective is to assess the safety, tolerability and preliminary activity of AB-101 plus rituximab after cyclophosphamide and fludarabine in adult subjects with relapsed/refractory lupus nephritis Class III or IV, with or without the presence of Class V. Patients will be assigned to receive either AB-101 alone as monotherapy or in combination with rituximab. All patients will receive at least 1 treatment cycle of AB-101, followed by scheduled assessments of overall health and response status. Patients may receive up to 2 cycles of treatment spaced 24 weeks apart.

A Clinical Study of Low-dose Total Body Irradiation and Fludarabine/Busulfan/Melphalan as a Conditioning Regimen for Secondary Umbilical Cord Blood Transplantation in Patients With Hematological Malignancies Who Relapsed After Allo-HSCT
About 33% of patients with myeloid or lymphoid malignancies experience relapse with HLA loss after haplo-HSCT. Due to the specificity of HLA-loss relapse, the 2019 European Society for Blood and Marrow Transplantation (EBMT) pointed out that for diagnosed HLA-loss patients, it is recommended to use different HLA-haploidentical donors, and lymphocyte infusions from the original donor cannot improve the prognosis. Clinical studies have found that second transplantation can achieve prolonged disease-free survival than chemotherapy for patients with HLA loss, and it may be an effective treatment strategy for these patients. However, due to the high standard of second hematopoietic stem cell transplantation (HSCT), not all patients can find suitable donors. Since the first successful application of umbilical cord blood transplantation (UCBT) by Gluckman et al. in France in 1988 for the treatment of Fanconi anemia, umbilical cord blood (UCB) has been widely used as a reliable source for HSCT in the treatment of hematological diseases. In 1998, Professor Yongping Song led the first successful UCBT in the treatment of leukemia, opening up the path of it in China. Compared with peripheral blood stem cell transplantation (PBST), UCBT has a higher engraftment rate. UCB contains more primitive and purer stem cells than bone marrow hematopoietic stem cells. UCBT can be performed with only 4 HLA matches, and the degree of rejection, the risk of disease relapse, and the incidence of chronic graft-versus-host disease (cGVHD) are all relatively low, greatly improving the survival of patients. Although UCBT has been a potential treatment for second transplantation, the effective conditioning regimen is still under discussion. Improving the incidence of engraftment , the tolerance of conditioning, and reducing transplant-related mortality (TRM) are issues of great concern in second transplantation. A standard RIC regimen composed of fludarabine (200mg/m2) combined with cyclophosphamide (50mg/kg) and 2Gy or 3Gy total body irradiation (TBI) is the most common conditioning regimen used in UCBT. Although the tolerance of this RIC is acceptable, the relapse rate after transplantation is relatively high, and the implantation failure rate is also high in high-risk populations. The inclusion of thiotepa (10mg/kg) combined with fludarabine, cyclophosphamide, and 4Gy TBI in an intensified version of the RIC regimen has improved the engraftment rate without increasing TRM. In addition, studies have also confirmed that increasing the dose of TBI can improve engraftment in transplant recipients at high risk of UCBT failure. The fludarabine/busulfan/melphalan (Flu/Bu/Mel) conditioning regimen was first used for salvaging UCBT in unresponsive hematological malignancies in 2016 and achieved good clinical outcomes. Subsequently, several transplant centers in Japan adopted the Flu/Bu/Mel conditioning regimen for UCBT and confirmed that, compared with the Flu/Bu4 regimen, it not only improved overall survival (OS) but also reduced disease relapse rate without increasing TRM. A recent multicenter retrospective study of UCBT in patients with acute myeloid leukemia in remission found that compared with the TBI/Cy conditioning regimen, the Flu/Bu/Mel conditioning regimen improved the engraftment rate and exerted the GVL effect, reducing NRM and improving OS. Based on the above, TBI/Flu/Bu/Mel as a conditioning regimen for secondary UCBT in patients with hematological malignancies who relapsed after allo-HSCT is safe and feasible, and is expected to improve the prognosis of these patients. Therefore, based on existing clinical experience with research evidence, our center plans to conduct a clinical study of low-dose TBI and FBM as a conditioning regimen for secondary UCBT in patients with hematological malignancies who relapsed after allo-HSCT, observing the improvement in the cumulative incidence of engraftment, disease relapse, GVHD, and survival rate in patients who received this regimen.

Phase 1 Trial of Umbilical Cord Blood Natural Killer Cells (CB-NK) Expressing Soluble IL-15 (sIL-15) and PD-L1 +/- Atezolizumab in Non-Small Cell Lung Cancer Patients Refractory to PD-1/PD-L1 Immune Checkpoint Inhibitors
This phase I trial studies the side effects and best dose of COH06 with or without atezolizumab in patients with non-small cell lung cancer previously treated with PD-1 and/or PD-L1 immune checkpoint inhibitors that has spread to other places in the body (advanced) and that has not responded to previous treatment (refractory). NK cells are infection fighting blood cells that can kill tumor cells. The NK cells given in this study, COH06, will come from umbilical cord blood and will have a new gene put in them that makes them express PD-L1, and express and secrete IL-15. NK cells that express PD-L1 may kill more tumor cells, and IL-15 may allow the NK cells to live longer. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving COH06 without or without atezolizumab may help control the disease in patients with non-small cell lung cancer.

Protocol for Evaluating the Safety and Efficacy of Transfusion of Umbilical Cord Blood in Patients With a Diagnosis of Autism Spectrum Disorder Depending on the Degree of Tissue Compatibility of the Donor and the Recipient
Autism is one of those disorders in Autism spectrum disorders (ASD), which characterized by social interaction abnormalities, impaired verbal and non-verbal communication, and repetitive, obsessive behavior, while the therapeutic effect of current treatments remains limited progress. The possible reason for ASD is neural hypoperfusion and immune dysregulation. The Human Umbilical Cord Blood Mononuclear Cells (hUCB-MNCs) have been shown to have the ability to modulate the immune response and enhance angiogenesis, suggesting the novel and promising therapeutic strategy. In this study, the safety and efficacy of hUCB-MNCs infusion will be evaluated in patients with Autism with regarding to HLA compatibility.

A Phase 2 Open-label Study to Evaluate the Efficacy of Allogeneic Human Cord Blood-derived Mesenchymal Stromal Cells in Maintaining Remission After Immunosuppressive Therapy Withdrawal in Pediatric Patients With Steroid-dependent Nephrotic Syndrome
A phase II open-label, single arm study aimed to ascertain whether infusions of cord-blood mesenchymal stromal cells (CB-MSCs) allow to reduce or suspend the chronic immunosuppressive therapy (IS) in steroid-dependent nephrotic syndrome (SDNS). We plan to enroll 11 patients aged 3 to 18 with SDNS in remission for at least one month, maintained by either ≥2 immunosuppressive drugs or a calcineurin inhibitor. Patients are infused with cord-blood allogenic MSC, selected by in-vitro alloreactivity, at a dose of 1.5x10^6/kg on days 0, 14, 21. The immunosuppressive treatment is gradually tapered starting at the first CB-MSC administration, according to the following scheme: 25% following the first administration, 50% following the second administration, and 100% reduction following the third administration. All patients will be followed-up for 6 months from the last CB-MSC. Study visits are planned at baseline during CB-MSC administrations, 2 weeks (follow-up [FU]1) and 6 weeks (FU2) after the last infusion, and then every 6 weeks. During follow-up, the patients undergo a physical examination (including measurement of height, weight and blood pressure) and laboratory evaluations (urinary protein:urinary creatinine ratio, complete blood count, kidney function, plasma proteins, liver function, triglycerides and cholesterol). In addition, a blood sample is taken for regulatory T lymphocyte quantification, a marker of clinical response to the infusions.
