For patients suffering from blood cancers and inherited blood disorders, an allogeneic hematopoietic stem cell transplantation (HSCT) is generally regarded as a potentially curative approach. During an HSCT treatment, the patient’s diseased blood and immune system are destroyed and subsequently replaced by a healthy system from a donor. The treatment is, however, very risky as it usually takes the patient at least six to twelve months to recover to near-normal immune cell functions, making patients highly vulnerable to infections and disease relapse. Mature lymphocytes in the donor graft would provide immediate protection, but, depending on the level of genetic mismatch between patient and donor, may cause life threatening Graft-versus-Host-Disease (GVHD). The Company estimates that approximately 35% of patients who are eligible and in urgent need of an HSCT will not find an adequately matched donor in time. A half-matched (haploidentical) parent or child, however, could serve as a donor for nearly all patients, yet would cause severe GVHD due to the infusion of half-matched mature lymphocytes. The therapy Kiadis Pharma is developing would enable the use of haploidentical transplants without the unacceptable risk of GVHD. ATIR101™ (Allodepleted T-cell ImmunotheRapeutics) provides for a safe single dose donor lymphocyte infusion (DLI) with functional, mature immune cells from a haploidentical family member with minimal risk of causing severe GVHD. ATIR101™ will help fight infections and remaining tumor cells and thereby bridge the time until the patient’s immune system has fully re-grown from stem cells in the transplanted graft. Kiadis Pharma is focused on cell-based immunotherapy products for the treatment of blood cancers and inherited blood disorders. The Company’s product candidates, ATIR101™ for blood cancers and ATIR201™ for inherited blood disorders, have the potential to make allogeneic hematopoietic stem cell transplantations (HSCT) safer and more effective. Based on the significant and positive results from the single dose Phase II trial with lead product ATIR101™ in patients with blood cancer, which were presented on December 5, 2016 at the Annual Meeting of the American Society of Hematology (ASH), the Company has initiated a Phase III trial with ATIR101™, having received regulatory approval in various countries to start dosing patients. In addition, and based on the positive Phase II results, the Company has submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for approval of ATIR101™ across Europe as an adjunctive treatment in HSCT for malignant disease . ATIR101™ has been granted Orphan Drug Designations both in the US and Europe. The Company’s second product candidate, ATIR201™, addresses inherited blood disorders with an initial focus on thalassemia. ATIR201™ Phase I/II clinical development has been initiated recently with regulatory approvals having been received in various European countries to start the trial. Kiadis Pharma was granted an Advanced Therapy Medicinal Product (ATMP) certificate for manufacturing quality and non-clinical data by the EMA.

Aim: To evaluate if indolent B cell-non Hodgkin's lymphoma (B-NHL) and diffuse large B-cell lymphoma (DLBCL) in hepatitis C virus (HCV) positive patients could have different biological and clinical characteristics requiring different management strategies. Methods: A group of 24 HCV related B-NHL patients (11 indolent, 13 DLBCL) in whom the biological and clinical characteristics were described and confronted. Patients with DLBCL were managed with the standard of care of treatment. Patients with indolent HCV-related B-NHL were managed with antiviral treatment pegylated interferon plus ribavirin and their course observed. The outcomes of the different approaches were compared. Results: Patients with DLBCL had a shorter duration of HCV infection and a higher prevalence of HCV genotype 1 compared to patients with indolent B-NHL in which HCV genotype 2 was the more frequent genotype. Five of the 9 patients with indolent HCV-related B-NHL treated with only antiviral therapy, achieved a complete response of their onco-haematological disease (55%). Seven of the 13 DLBCL patients treated with immunochemotheraphy obtained a complete response (54%). Conclusion: HCV genotypes and duration of HCV infection differed between B-NHL subtypes. Indolent lymphomas can be managed with antiviral treatment, while DLBCL is not affected by the HCV infection. © 2011 Baishideng.

Several studies in mouse model of invasive aspergillosis (IA) and in healthy donors have shown that different Aspergillus antigens may stimulate different adaptive immune responses. However, the occurrence of Aspergillus-specific T cells have not yet been reported in patients with the disease. In patients with IA, we have investigated during the infection: a) whether and how specific T-cell responses to different Aspergillus antigens occur and develop; b) which antigens elicit the highest frequencies of protective immune responses and, c) whether such protective T cells could be expanded ex-vivo. Forty hematologic patients have been studied, including 22 patients with IA and 18 controls. Specific T cells producing IL-10, IFN-γ, IL-4 and IL-17A have been characterized through enzyme linked immunospot and cytokine secretion assays on 88 peripheral blood (PB) samples, by using the following recombinant antigens: GEL1p, CRF1p, PEP1p, SOD1p, α1-3glucan, β1-3glucan, galactomannan. Specific T cells were expanded through short term culture. Aspergillus-specific T cells producing non-protective interleukin-10 (IL-10) and protective interferon-gamma (IFN-γ) have been detected to all the antigens only in IA patients. Lower numbers of specific T cells producing IL-4 and IL-17A have also been shown. Protective T cells targeted predominantly Aspergillus cell wall antigens, tended to increase during the IA course and to be associated with a better clinical outcome. Aspergillus-specific T cells could be successfully generated from the PB of 8 out of 8 patients with IA and included cytotoxic subsets able to lyse Aspergillus hyphae. Aspergillus specific T-cell responses contribute to the clearance of the pathogen in immunosuppressed patients with IA and Aspergillus cell wall antigens are those mainly targeted by protective immune responses. Cytotoxic specific T cells can be expanded from immunosuppressed patients even during the infection by using the above mentioned antigens. These findings may be exploited for immunotherapeutic purposes in patients with IA. © 2013 Potenza et al.
