Trastuzumab Deruxtecan (DS-8201a) versus Investigator's Choice bei HER2-niedrigem Brustkrebs, der sich ausgebreitet hat oder nicht chirurgisch entfernt werden kann [DESTINY-Breast04]

1. September 2026 aktualisiert von: Daiichi Sankyo

Eine multizentrische, randomisierte, offene, aktiv kontrollierte Phase-3-Studie mit DS-8201a, einem Anti-HER2-Antikörper-Wirkstoffkonjugat (ADC), im Vergleich zu einer Behandlung nach Wahl des Arztes für Patienten mit HER2-niedrigem, nicht resezierbarem und/oder metastasierendem Brustkrebs

This study will compare DS-8201a to physician choice standard treatment.

Participants must have HER2-low breast cancer that has been treated before.

Participants' cancer:

  • Cannot be removed by an operation
  • Has spread to other parts of the body

Zeitfenster
Progression-free Survival (PFS) Based on Blinded Independent Central Review (BICR) in the Hormone Receptor-Positive Cohort in Participants With HER2-low Breast Cancer
Zeitfenster: From the date of randomization to the earliest date of the first objective documentation of radiographic disease progression or death due to any cause, up to approximately 3 years

Progression-free survival (PFS), defined as at least a 20% increase in the sum of diameters of target lesions, was assessed from the date of randomization to the date of the first radiographic disease progression or death due to any cause, whichever came first. PFS was based on blinded independent central review (BICR) in the hormone receptor-positive cohort according to modified Response Evaluation Criteria in Solid Tumors (mRECIST) version 1.1. Median PFS was from Kaplan-Meier analysis. Confidence interval for median was computed using the Brookmeyer-Crowley method.

Overall Survival (OS) in the Hormone Receptor-Positive Cohort in Participants With HER2-low Breast Cancer
Zeitfenster: From the date of randomization up to the date of death due to any cause, up to approximately 3 years

Overall survival (OS) was defined as the time from the date of randomization to the date of death due to any cause. If there was no death reported for a participant before the data cutoff for OS analysis, OS was censored at the last contact date at which the participant was known to be alive.

Best Overall Response and Confirmed Objective Response Rate (ORR) in the Hormone Receptor-Positive Cohort in Participants With HER2-low Breast Cancer
Zeitfenster: From screening and every 6 weeks up to withdrawal of subject consent, progressive disease (PD), or unacceptable toxicity, up to approximately 3 years

Best overall response rate and confirmed objective response rate (ORR) were assessed by blinded independent central review (BICR) and investigator assessment. Complete response (CR) was defined as a disappearance of all target lesions, partial response (PR) was defined as at least a 30% decrease in the sum of diameters of target lesions, and stable disease (SD) was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD; at least a 20% increase in the sum of diameters of target lesions. Confirmed ORR was defined as the number of participants with complete and partial responses and confirmed by a second assessment.

Duration of Response (DoR) is defined as the date of the first documented objective response (complete response [CR] or partial response [PR]) to the first documented disease progression or death, whichever occurs first. DoR was based on blinded independent central review (BICR) and investigator assessment. Median was from Kaplan-Meier estimate. Confidence interval for median was computed using the Brookmeyer-Crowley method.
