BioNTech (BNTX)BioNTechClinical readout

MAINZ, Deutschland und SHANGHAI, China, 26. Oktober 2026 – BioNTech SE (Nasdaq: BNTX, „BioNTech“) and DualityBiologics (Suzhou) Co., Ltd. („DualityBio“, HKEX: 9606.HK) gaben heute bekannt, dass die globale klinische Phase-3-Studie DYNASTY-Breast02 ( NCT06018337 ) ihren primären Endpunkt erreicht hat. Die Studie zeigte für Trastuzumab Pamirtecan (BNT323/DB-1303) im Vergleich zu einer vom Prüfarzt ausgewählten Chemotherapie eine statistisch signifikante, jedoch moderate Verbesserung des progressionsfreien Überlebens (progression-free survival, „PFS“) bei Chemotherapie-naïven Patientinnen und Patienten mit Hormonrezeptor-positivem (Hormone Receptor-positive, „HR+“) metastasiertem Brustkrebs, deren Tumoren niedrige HER2-Expressionslevel („HER2-low“) aufweisen und deren Erkrankung unter einer endokrinen Therapie fortgeschritten war. Die Daten für die zum gleichen Zeitpunkt erfolgte Zwischenanalyse des sekundären Endpunktes, dem Gesamtüberleben (overall survival, „OS“), waren noch nicht ausgereift.
