1. A stable composition formulated for subcutaneous administration, wherein:

  • the stable composition contains hyaluronidase and immune globulin (IG);

    the stable composition is a liquid co-formulation;

    the composition has a pH of between 4 or about 4 to 5 or about 5, inclusive; and

    the composition comprises;

    (a) immune globulin (IG) at a concentration that is at least 10% w/v;

    a soluble hyaluronidase at a concentration that is at least 50 U/mL and is present in an amount sufficient to allow for the subcutaneous administration of the composition at a single injection site at an infusion rate equal to or greater than the intravenous infusion rate for intravenous immunoglobulin; and

    an alkali metal chloride salt at a concentration of 0.05 M to 0.25 M, whereby the co-formulated composition is stable at temperatures of 28°

    C. to 32°

    C. for at least 6 months;

    or(b) immune globulin (IG) at a concentration that is at least 10% w/v;

    a soluble hyaluronidase at a concentration that is at least 50 U/mL and is present at a ratio of at least 100 Units (U) of hyaluronidase per gram (g) of the IG; and

    an alkali metal chloride salt at a concentration of 0.05 M to 0.25 M, whereby the co-formulated composition is stable at temperatures of 28°

    C. to 32°

    C. for at least 6 months.
