Abstract: Provided is a method for preparing a peptide emulsion formulation capable of preparing a desired peptide emulsion formulation. A method for preparing a peptide emulsion formulation includes a step of mixing an aqueous solution containing a compound consisting of an amino acid sequence represented by Formula (1), a pharmaceutically acceptable salt thereof, and a peptide consisting of an amino acid sequence represented by WAPVLDFAPPGASAYGSL (SEQ ID NO: 1) or a pharmaceutically acceptable salt thereof with an oily formulation and applying vibration mixing; and a membrane emulsification step of passing a premixed solution after the vibration mixing through a membrane filter to emulsify the premixed solution.

Abstract: The present invention relates to a lyophilized preparation comprising two or more cancer antigen peptides derived from WT1 protein with an activity of inducing cytotoxic T lymphocytes for cancer peptide vaccine therapy.

Abstract: The present invention provides an aqueous suspension preparation comprising (3aR,4S,7R,7aS)-2-{(1R,2R)-2-[4-(1,2-benzisothiazol-3-yl)piperazin-1-ylmethyl]cyclohexylmethyl}hexahydro-4,7-methano-2H-isoindole-1,3-dione (Compound 1), a pharmaceutically acceptable acid addition salt thereof, or a mixture thereof as an active ingredient, which has the following feature (I) or (II): (I) the circularity of the suspended particle is about 0.960 or less when the preparation comprises a thickening agent, (II) the circularity of the suspended particle is about 0.945 or less when the preparation comprises no thickening agent.
