  • Patent number: 12330024
    Abstract: A color coating solution is produced by dispersing a nano-color pigment and a metallic gloss pigment into a polymer resin, and the solution is coated and molded on a cover layer having a color similar to that of the color coating solution. Since the pigment composition is different between the cover layer and the color coating layer, internal shieldability is improved. As a result, a dark color or uneven surface of the core, mantle, or cover is not exposed, so that a surface defect rate can be reduced. Since both the nano-color pigment and the metallic gloss pigment are used in the color coating layer, the metallic gloss and the color are exhibited in a single layer. Therefore, it is possible to provide natural metallic gloss without a strange texture feeling.

  • Publication number: 20240059767
    Abstract: The present invention relates to treatment of dry eye syndrome using a tanfanercept-containing ophthalmic composition. According to the present invention, as a result of clinical trial on dry eye syndrome, the tanfanercept-containing ophthalmic composition demonstrated excellent effects with regard to improvement of a central corneal staining score (CCSS) and a total corneal staining score (TCSS), which is clinically important. Further, such improvement of a central corneal staining score (CCSS) and a total corneal staining score (TCSS) was more significantly demonstrated in the patients with moderate-to-severe severity of dry eye. In addition, the patients with higher ocular discomfort score or higher eye dryness score, which are subjective symptoms, also showed greater improvement. Even though the same dose of tanfanercept was used, the tanfanercept-containing ophthalmic composition showed superior efficacy in the patient having more serious or severe baseline sign or symptom scores.

  • Publication number: 20240059768
    Abstract: The present invention relates to a stable ophthalmic composition comprising tanfanercept, which does not use a stabilizer, and methods of preparing and using the composition. According to the present invention, it was found that the use of a stabilizer such as histidine or sucrose causes the generation of impurities such as tanfanercept-derived acidic/basic variants, and affects biological activity. The ophthalmic pharmaceutical composition according to the present invention may control pH rather than excluding the use of such a stabilizer to significantly reduce the generation of impurities under not only a refrigerated storage condition but also accelerated conditions and a stress condition, thereby preparing a stable tanfanercept ophthalmic composition.
