| Description | Peginterferon beta-1a is an interferon beta-1a to which a single, linear 20,000 dalton (Da) methoxy poly(ethyleneglycol)-O-2-methylpropionaldehyde molecule is covalently attached to the alpha amino group of the N-terminal amino acid residue. The interferon beta-1a portion is produced as a glycosylated protein using genetically-engineered Chinese hamster ovary cells into which the human interferon beta gene has been introduced. The amino acid sequence of the recombinant interferon beta-1a is identical to that of the human interferon beta counterpart. |
| Indication/Disease | For the treatment of patients with relapsing forms of multiple sclerosis. |
| Pharmacodynamics | There is no biochemical or physiologic effect known to relate directly to the clinical effect of PLEGRIDY. |
| Mechanism of Action | The mechanism by which PLEGRIDY exerts its effects in patients with multiple sclerosis is unknown. |
| Toxicity | NA |
| Metabolism | Clearance mechanisms for PLEGRIDY include catabolism and excretion. The major pathway of elimination is renal. |
| Absorption | The mean Cmax was 280 pg/mL, and the AUC over the 14 day dosing interval was 34.8 ng.hr/mL. |
