Summary for Patent: 9,649,383
Title: | Liquid formulations for TNFR:Fc fusion proteins |
Abstract: | The invention provides stable liquid formulations for a recombinant biopharmaceutical protein comprising a soluble form of the human p75 TNF receptor fused to an Fe domain of a human immunoglobulin protein (TNFR:Fc). Typically, biopharmaceutical proteins such as monoclonal antibodies (mAbs) and immunoglobulin fusion proteins (e.g., immunoadhesion proteins) are produced by recombinant DNA technology in mammalian cell expression systems. In order to guarantee the reproducible clinical performance of a biopharmaceutical product, manufacturers have to deliver a product of consistent and reproducible quality. |

Application Number: | 14/443,557 |
Patent Claims: | 1. A stable liquid pharmaceutical formulation comprising 50 mg/ml etanercept, a citrate-phosphate buffer, 100 or 125 mM sodium chloride, L-histidine, and sucrose, pH 6.0-6.5.
2. The formulation of claim 1, wherein the amino acid is L-histidine at a concentration of 25 mM. 3. The formulation of claim 2, wherein the sugar is present at a concentration of about 1%. 4. The formulation of claim 1, comprising 50 mg/ml etanercept, a 25 mM citrate-phosphate buffer pH 6.3, 100 mM sodium chloride, 25 mM L-histidine and 1% sucrose. 5. The formulation of claim 1 wherein etanercept exhibits stability over at least about 12 months. |
