An extended release oral dosage form comprising as active substance tacrolimus or a pharmaceutically active analogue thereof for a once daily immunosuppressive treatment of a patient in need thereof, preferable a kidney or liver transplant patient. The dosage form releases the active substance over an extended period of time. It also provides improved pharmacokinetic parameters due to an extended and constant in vivo release including substantial decreased peak concentrations, despite increased bioavailability, substantial extended times for maximal concentration, and higher minimal concentrations when compared with conventional immediate release dosage forms and a recent modified release tacrolimus dosage form.

The present invention provides a method for reducing the risk of bacterial infection or sepsis in a susceptible patient by treating the susceptible patient with a pharmaceutical composition containing bacteriophage of one or more strains which produce lytic infections in pathogenic bacteria. Preferably, treatment of the patient reduces the level of colonization with pathogenic bacteria susceptible to the bacteriophage by at least one log. In a typical embodiment, the susceptible patient is an immunocompromised patient selected from the group consisting of leukemia patients, lymphoma patients, carcinoma patients, sarcoma patients, allogeneic transplant patients, congenital or acquired immunodeficiency patients, cystic fibrosis patients, and AIDS patients. In a preferred mode, the patients treated by this method are colonized with the pathogenic bacteria subject to infection by said bacteriophage.

The present invention provides a comprehensive tissue management system for transplantable materials like tissues and organs. The tracking portion of the system prompts and verifies that staff members of a medical establishment like a hospital have handled, stored, transported, reconstituted, and used the tissue or organ materials in a safe and regulatory-compliant manner from the point of receipt to the point of issuance or surgical use throughout the hospital's organization. The tracing portion of the system creates an integral record that documents which hospital staff members have provided which processing steps to the tissue or organ, any associated materials used in conjunction with such tissue or organ, and an identification of the tissue or organ that was transplanted or implanted inside a patient. Such a system will enable adverse reaction investigations for transplant patients, and recalls of transplantable materials.

The present invention relates to a method for predicting whether or not transplant recipients are likely to reject tissue allografts. It is based, at least in part, on the discovery that based on analysis of three immunologic factors, cardiac transplant recipients could be classified into risk categories for progression to high-grade rejection. The present invention, by enabling a determination of the risk for high-risk rejection in a transplant patient, reduces unnecessary diagnostic and therapeutic procedures in low risk patients and clinical intervention in patients who would most benefit.

The object of the invention is to provide an immunological reconstitution promoter or a prophylactic agent for infections for use in allogeneic hematopoietic stem cell transplantation therapy for tumors. The promoter or prophylactic agent enables the amelioration of delayed immune reconstitution or the prevention of infection following transplantation, while maintaining the GVT effect of allogeneic hematopoietic stem cell transplantation. Specifically, in a transplant patient in whom immune reconstitution is delayed, such reconstitution can be promoted by administering, at an early stage following transplantation, a substance capable of depleting CD4+ cells. Early completion of infection management in the patient and improvement in the survival rate are anticipated as a result. In addition, the risk of complications associated with allogeneic hematopoietic stem cell transplantation is reduced, enabling more widespread use of this therapy.

The invention encompasses a method of down-regulating a T cell-mediated immune response, through activation or T cell receptor (TCR) stimulation of antigen-primed T cells in the presence of alpha-melanocyte stimulating hormone (α-MSH), which may be optionally enhanced by adding transforming growth factor-β2 (TGF-β2) approximately 4-6 hours after the start of the primed T cells' exposure to α-MSH. Activation of the primed T cells may be mediated by presentation of the specific antigen to the primed T cells, or by an anti-TCR antibody or a T cell mitogen. As a result of the α-MSH treatment modulating the T cell activation, antigen-specific, regulatory, CD4+ / CD25+ T cells are generated that produce transforming growth factor-β (TGF-β) and can non-specifically down-regulate Th1-mediated inflammatory activities. The method may be used to down-regulate or suppress an autoimmune condition or a graft rejection in a transplant patient. The invention also encompasses a kit for generating regulatory T cell comprising a specific antigen, α-MSH, and optionally, TGF-β2 and / or a T cell culture medium. Also provided are gene therapy treatments for suppressing an autoimmune or graft rejection response, or for re-establishing autotolerance, by introducing genetic material (e.g. nucleic acid) for expressing α-MSH or a receptor-binding portion thereof, into a localized tissue site.

The invention relates to suppressors of endogenous human interferon-gamma (INF-γ) applicable in treatment of diseases associated with impaired activity of endogenous IFN-γ.

The invention includes inactive analogues or variants of IFN-γ having preserved affinity to the IFN-γ receptor, genetically modified in the domain responsible for triggering the signal transduction pathway.
