Zusammenfassung:The present invention relates to a formulation optimized for a fusion protein dimer including an extracellular domain of an alpha sub-unit of an IgE Fc receptor, and more specifically, to an aqueous pharmaceutical formulation having a pH of 6.0-7.0, comprising a fusion protein dimer including an extracellular domain of an alpha sub-unit of an IgE Fc receptor, histidine, proline, methionine, and Poloxamer 188. The fusion protein present in the formulation according to the present invention is contained at a high concentration, has improved stability, and thus can be easily administered through sub-cutaneous injection, and has excellent IgE-binding capacity as compared to existing therapeutic agents comprising an anti-IgE antibody, and thus can be usefully utilized in an injection for treating an IgE-mediated allergic disease. 본 발명은 IgE Fc 수용체의 알파 서브유닛의 세포외 도메인을 포함하는 융합단백질 이량체에 최적화된 제형에 관한 것으로, 상세하게는 IgE Fc 수용체의 알파 서브유닛의 세포외 도메인을 포함하는 융합단백질 이량체, 히스티딘, 프롤린, 메티오닌 및 폴록사머 188을 포함하는 pH 6.0 내지 7.0의 수성 약제학적 제형에 관한 것이다. 본 발명에 따른 제형 내 존재하는 상기 융합단백질은 고농도로 포함되며 안정성이 개선되어 피하 주사로 편리하게 투여 가능하며, 기존의 항 IgE 항체를 포함하는 치료제에 비하여 IgE 결합능이 우수한 바, IgE에 의해 매개되는 알레르기 질환 치료용 주사제로 유용하게 활용될 수 있다.
