- Amounts effective will depend, of course, on the particular subject being treated; the severity of a condition, disease or disorder; the individual patient parameters including age, physical condition, size and weight; the duration of the treatment; the nature of concurrent therapy (if any); the specific route of administration and like factors within the knowledge and expertise of the health practitioner. These factors are well known to those of ordinary skill in the art and can be addressed with no more than routine experimentation. It is generally preferred that a maximum dose be used, that is, the highest safe dose according to sound medical judgment. It will be understood by those of ordinary skill in the art, however, that a patient may insist upon a lower dose or tolerable dose for medical reasons,
- doses of the immunosuppressants and/or therapeutic macromolecules in the compositions of the invention refer to the amount of the immunosuppressants and/or therapeutic macromolecules.
- the dose can be administered based on the number of synthetic nanocarriers that provide the desired amount of immunosuppressants.
- Antigen means a B cell antigen or T cell antigen.
- Type(s) of antigens means molecules that share the same, or substantially the same, antigenic characteristics.
- antigens may be proteins, polypeptides, peptides, lipoproteins, glycolipids, polynucleotides, polysaccharides or are contained or expressed in cells.

- Antigen-specific refers to any immune response that results from the presence of the antigen, or portion thereof, or that generates molecules that specifically recognize or bind the antigen.
- antigen- specific may mean therapeutic macromolecule- specific.
- the immune response is antigen-specific antibody production, such as therapeutic macromolecule- specific antibody production, antibodies are produced that specifically bind the antigen (e.g., therapeutic macromolecule).

Such measurements or determinations may be performed on one or more samples obtained from a subject. Such assessing can be performed with any of the methods provided herein or otherwise known in the art.
- attaching means to chemically associate one entity (for example a moiety) with another.
- the attaching is covalent, meaning that the attachment occurs in the context of the presence of a covalent bond between the two entities.
