USE OF NANOPARTICLES COATED WITH RED BLOOD CELL MEMBRANES TO TREAT HEMOLYTIC DISEASES AND DISORDERS

摘要

The present invention relates to methods, combinations and pharmaceutical compositions for treating or preventing a hemolytic disease or condition in a mammal, wherein: said hemolytic disease or condition is caused by an attack of said mammal's red blood cells by said mammal's own body, or said mammal is a pregnant mammal and said hemolytic disease or condition of a fetus of said pregnant mammal is caused by an attack of said fetus' red blood cells by an antibody of said pregnant mammal, or said mammal is a baby and said hemolytic disease or condition of said baby is caused by an attack of said baby's red blood cells by an antibody of said baby's mother. The exemplary hemolytic diseases or conditions include hemophagocytic lymphohistiocytosis, an autoimmune disease or condition, or a hereditary hemolytic disease or disorder.

主权项

1. A method for treating or preventing a hemolytic disease or condition in a mammal, which method comprises administering, to a mammal in need of treatment or prevention of a hemolytic disease or condition, an effective amount of a nanoparticle comprising a) an inner core comprising a non-cellular material, and b) an outer surface comprising a cellular membrane derived from a red blood cell, wherein:
said hemolytic disease or condition is caused by an attack of said mammal's red blood cells by said mammal's own body, or said mammal is a pregnant mammal and said hemolytic disease or condition of a fetus of said pregnant mammal is caused by an attack of said fetus' red blood cells by an antibody of said pregnant mammal, or said mammal is a baby and said hemolytic disease or condition of said baby is caused by an attack of said baby's red blood cells by an antibody of said baby's mother.
