      NAGOYA, Japan, 21. April 2025 /PRNewswire/ -- Kowa Company, Ltd. (Hauptsitz:Nagoya, Präfektur Aichi, Japan), kündigte heute die bevorstehende Präsentation nicht-klinischer Daten für K-679 an, sein neuartiges, mit Antikörpern beladenes, unimizelluläres Konjugat (ADUC) mit einer noch nie dagewesenen Wirkstoffbeladungskapazität. Der Wirkstoff, der mit Hilfe der von Kowa entwickelten Mizellentechnologie entwickelt wurde, hat sich bei EGFR-exprimierenden soliden Tumoren im Vergleich zu herkömmlichen Antikörper-Wirkstoff-Konjugaten (ADCs) als besonders wirksam erwiesen. Die Daten werden auf der The American Association for Cancer Research (AACR) Annual Meeting 2025 vorgestellt, die vom 25. bis 30. April 2025 in Chicago, Illinois, stattfindet.

      Details zur Präsentation 
      Titel der Präsentation:
      K-679: Ein neuartiges, mit Antikörperwirkstoffen beladenes Unimicelle-Konjugat (ADUC) mit extrem hohem DAR-Wert, das im Vergleich zu allgemeinen ADCs eine wirksamere Behandlung von EGFR-exprimierenden soliden Tumoren ermöglicht.
      Titel der Sitzung: Novel Drug Delivery Technologies
      Datum und Uhrzeit der Präsentation: 28. April 2025, 9:00 - 12:00 Uhr CST (10:00 - 13:00 Uhr ET)
      Veröffentlichte Abstract-Nummer: 1798
      Moderatorin: Hideo Yoshida

      Die Zusammenfassung der Präsentation finden Sie unter

      Über K-679
      K-679 ist ein Antikörper-Arzneimittel-geladenes Unimicelle-Konjugat (ADUC), ein neuartiger ADC-Typ, der Kowa patentrechtlich geschützte Mizellentechnologie nutzt und sich derzeit im nicht-klinischen Stadium befindet. Das Konjugat kombiniert einen Anti-EGFR-Antikörper mit arzneimittelbeladenen Unimicellen (DM1), die erhebliche Mengen von Nutzlasten in ein einkettiges Polymer einbauen. Mit diesem innovativen Ansatz wird ein extrem hohes DAR-Verhältnis (Drug-to-Antibody Ratio) von etwa 40 DM1-Molekülen pro Antikörper erreicht, was deutlich höher ist als bei herkömmlichen ADCs.

      In nicht-klinischen Studien hat K-679 in Xenograft-Modellen eine starke Anti-Tumor-Wirkung gezeigt und übertrifft damit herkömmliche ADCs. Insbesondere hat K-679 eine bemerkenswerte Wirksamkeit bei EGFR-positiven und -negativen heterogenen Tumoren gezeigt, wobei es signifikante Bystander-Killing-Effekte aufwies.
