摘要:
Monoclonal anti-human CD20 antigen binding antibodies containing human IgG3 constant domains are provided. These antibodies possess effector functions that render them well suited for use in therapeutic methods, especially treatments wherein inhibition of B cell function or B cell number is therapeutically desirable.
摘要:
The present invention provides a synergistic composition and methods for treating neoplastic or cancerous growths as well as for treating such patients in order to restore or boost hematopoiesis. The present invention comprises administration of the combination of a cytotoxic T-lymphocyte inducing composition and at least one agent which is capable of neutralizing or down regulating the activity of tumor secreted immunosuppressive factors, separately or in combination.
摘要:
The use of a chimeric anti-CD20 antibody, RITUXANnull, as an in vivo or in vitro purging agent, of patients receiving bone marrow or peripheral blood stem cell transplant during treatment of B-cell-related malignancies, e.g., B-cell lymphomas or leukemias, is disclosed. Such purging may enhance engraftment and/or prevent disease relapse in such patients.
摘要:
Methods for treating B cell malignancies, in particular B cell leukemia and lymphoma, using an anti-CD80 antibody alone or in combination with an anti-CD20 antibody or chemotherapy is provided. These methods result in a synergistic anti-tumor response.
摘要:
Described herein is a novel expression system for producing multiple gene products of interest from a single polycistronic construct. In particular, the expression system contains a polycistronic vector capable of expressing functional antibodies in eukaryotic host cells, which vector contains at least the following elements operably linked in the 5null to 3null orientation: a promoter operable in a eukaryotic cell; a DNA sequence encoding at least the variable region of an antibody light chain; an internal ribosome entry site (IRES); and at least one DNA sequence encoding an antibody heavy chain. Also disclosed are mammalian cells containing the polycistronic expression vector, and a method of producing functional antibodies in mammalian cells transfected with the polycistronic expression vector.
摘要:
Chimeric antibodies specific to human CD4 antigen, DNA encoding, pharmaceutical compositions containing and use thereof as therapeutic agents are taught. These chimeric antibodies contain Old World monkey variable sequences and human constant domain sequences, preferably human gamma 1, gamma 4 or mutated forms thereof. These antibodies possess desirable therapeutic properties including low antigenicity, reduced (or absent) T cell depleting activity, good affinity to human CD4 and enhanced stability (in vivo half-life).
摘要:
New combined therapeutic regimens for treatment of B-cell lymphomas are disclosed which comprise in particular administration of anti-CD20 antibodies to patients having low-, intermediate- or high-grade non-Hodgkins lymphomas.
摘要:
Chimeric antibodies including an Old World monkey portion and a human portion, nucleic acid encoding such antibodies, Old World monkey monoclonal antibodies, and methods for their production and use.
摘要:
An improved method for producing human antibodies in SCID mice is provided. The improvement includes the use of dendritic cells pulsed with antigen-antibody complexes and antigen-antibody complexes as immunizing agents.
摘要:
A combination antibody therapy for treating B cell malignancies using an immunoregulatory antibody, especially an anti-B7, anti-CD23, or anti-CD40L antibody and a B cell depleting antibody, especially anti-CD19, anti-CD20, anti-CD22 or anti-CD37 antibody is provided.
