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.

Abstract
Provided herein are stable co-formulations of immunoglobulin and hyaluronidase that are stable to storage in liquid form at room temperature for at least 6 months and at standard refrigerator temperatures for 1-2 years. Such co-formulations can be used in methods of treating IG-treatable diseases or conditions by subcutaneous administration.
