The present invention relates to methods and kits for predicting the survival time of a patient suffering from a diffuse large B-cell lymphoma (DLBCL). In particular, the present invention relates to a method for predicting the survival time of a patient suffering from a diffuse large B-cell lymphoma (DLBCL) comprising the step of i) determining the level of sPD-L1 in a blood sample obtained from the patient ii) comparing the level determined at step i) with a predetermined reference value and iii) concluding that the patient has a poor prognosis when the level determined at step i) is higher than the predetermined reference value or concluding that the patient has a good prognosis when the level determined at step i) is lower than the predetermined reference value.

Osteoarthritis (OA) is an incurable disease that has evaded pharmacological interference, biologic therapy or surgical intervention to prevent disease progression. Currently, OA is designated the 11th highest contributor (of 291 diseases) of global disability. In the absence of effective treatment options, cellular therapies using mesenchymal stem/stromal cells (MSCs) have emerged as potential candidates to overcome this clinical short-coming. Autologous adipose-derived mesenchymal stromal cells (ASCs) are attractive for cellular therapy given the abundance of tissue, high frequency of MSCs and minimally invasive harvest procedure. The EU consortium ADIPOA has shown in a first in man 2-centre Phase I safety study that intraarticular injection of a single dose of autologous ASCs to the knee (18 patients, 12 month follow-up) was well-tolerated, had no adverse effects, and resulted in an improvement in pain score and functional outcome. ADIPOA2 will deliver a large-scale clinical trial in regenerative medicine for OA. The purpose of the project is to design and implement a phase IIb study to assess the safety and efficacy of autologous (patient-derived) ACSs in the treatment of advanced OA of the knee. The cells will be prepared from samples of adipose tissue harvested from patients by lipoaspiration. ADIPOA2 will comprise a multi-centre, randomized clinical trial comparing culture-expanded, autologous adult ASCs in subjects with knee OA with another widely used therapeutic approach for knee degeneration (injection of Hyaluronan). There are two large elements of the study: (1) the production of consistent batches of high-quality autologous ASCs under GMP-compliant conditions and (2) delivery of these cell doses to patients in a trial which will meet all national and European regulatory and ethical standards and which will have sufficient statistical power to provide an unambiguous and definitive assessment of safety and efficacy.

The key therapeutic issue in diabetes mellitus type I and II is glycaemic control. Reductions of constant self-control, of insulin injections, and of long-term complications would have tremendous benefit for quality of life. The best therapy option is the transplantation of allogeneic islet cells, but the current state of the art limits the applicability of this approach. Implanting unprotected grafts requires lifelong administration of immunosuppressants, and protecting the cells against adverse immune reactions by current encapsulation strategies reduces their functionality and survival to an extend that makes frequent refresher implantations necessary. Currently, a maximum of 2 years glycaemia regulation has been shown for the encapsulated approach. In BIOCAPAN, bringing experts from different fields all together, we aim at developing an innovative treatment, based on the implantation of allogeneic islet cells that are embedded in a complex microcapsule. We will design a GMP-grade bioactive microcapsule that will maximize the long-term functionality and survival of pancreatic islets by prevention of pericapsular fibrotic overgrowth, in situ oxygenation, innovative extracellular matrix microenvironment reconstruction and immune-system modulation. We will establish a GMP-grade microfluidic microencapsulation platform to protect freshly harvested islets quickly in a standardized and reproducible way. We aim for full preclinical validation and we will establish a complete protocol in accordance with the provisions of the Advanced Therapy Medicinal Products Regulation, in order to start clinical trials within one year after the end of the project. We aim for 5-years insulin injection free treatment, without immunosuppressants, which would tremendously benefit diabetes mellitus patients who require insulin (all Type I and about one in six Type II Diabetes Mellitus patients).

Nearly half a century has passed since the publication of the first articles describing plastic-adherent cells from bone marrow, referred to initially as colony-forming unit fibroblasts, then marrow stromal cells, mesenchymal stem cells and most recently multipotent mesenchymal stromal cells (MSCs). As expected, our understanding of the nature and biologic functions ofMSCs has undergone major paradigm shifts over this time. Despite significant advances made in deciphering their complex biology and therapeutic potential in both experimental animal models and human clinical trials, numerous misconceptions regarding the nature and function of MSCs have persisted in the field. Continued propagation of these misconceptions in some cases may significantly impede the advancement of MSC-based therapies in clinical medicine. We have identified six prevalent misconceptions about MSCs that we believe affect the field, and we attempt to rectify them based on current available data. © 2013, International Society for Cellular Therapy.

Bone is among the most frequently transplanted tissue with about 1 million procedures annually in Europe. The worldwide market of bone replacement materials is currently estimated at 5 billion with a 10% annual growth. Despite their considerable disadvantages, including the risk of disease transfer and immunologic rejection, limited supply of bone, costs and complications, allografts and autografts account for more than 80% of total graft volume. Significant growth opportunities exist for synthetic bone grafts in association with mesenchymal stem cells from autologous or allogenic sources as alternatives to biological bone grafts in orthopaedic and maxillofacial surgery. The objectives of REBORNE is to perform clinical trials using advanced biomaterials and cells triggering bone healing in patients. In order to reach this goal, five phase II clinical studies with 20 patients are proposed in 12 clinical centres spread in 8 European countries. Three orthopaedic trials concerning the treatment of long bone fractures and osteonecrosis of the femoral head in adults or children will be conducted using bioceramics, hydrogel for percuteneous injection and stem cells from autologous or allogenic sources. Clinical research will also concern maxillofacial surgery with bone augmentation prior to dental implants and the reconstruction of cleft palates in children. The safety and efficacy of the new therapies will be assessed clinically using X-rays, CT scans and MRI as well as histology of biopsies. These ambitious clinical targets will require research and development efforts from a large consortium of top world class laboratories, SMEs manufacturing biomaterials, GMP-cell producing facilities and surgeons in hospitals as well as the consideration of ethical and regulatory issues. It is expected that REBORNE will expand the competitiveness of Europe through the patenting of new CE-marked bioproducts in the field of regenerative medicine.
