Design:

 

A Phase 3, Randomized, Multi-center, Open-label Study of Trastuzumab Deruxtecan (T-DXd) Versus Investigator's Choice Chemotherapy.

 

Op 22Dec'22 is de IHC >0 <1+ subgroup gesloten voor screening.

Op15Dec'22 is de IHC2+ subgroep gesloten voor screening. 

Op 28Oct'22 is de IHC1+ subgroep gesloten voor recruitment.

 

 

Objectives:

 

Primary study objectives:

To assess the efficacy of trastuzumab deruxtecan compared to chemotherapy on progression free survival (PFS) of the population

 

Secondary study objectives:

  • Assess the efficacy of trastuzumab deruxtecan compared to chemotherapy on overall survival (OS) of the population
  • Assess the efficacy of trastuzumab deruxtecan compared to chemotherapy on overall survival (OS) in the HER2 ICH>0<1 sub-group
  • Compare the 2 treatment arms in terms of ORR, DoRPFS2, TFST, TSST, HRQoL
  • Assess the safety of trastuzumab deruxtecan
  • Investigate the PK and immunogeneticity of trastuzumab deruxtecan

 

Exploratory study objectives:

  • To collect blood and tissue samples for defining biological responses to trastuzumab deruxtecan and identifying candidate markers that may correlate with likelihood of clinical benefit
  • To explore the impact of treatment and disease state on health utility using the EQ-5D-5L
  • To assess patient-reported treatment tolerability
  • To assess the patient’ overall impression of the severity of their cancer symptoms and change in condition since starting the study
  • To explore the impact of treatment and disease on health care resource use
  • To explore & optimize technologies for detection of HER2 protein expression
Endpoints:

 

Progression Free Survival (PFS) - in HR+, HER2-low populaton

Main eligibility criteria:

 

Key Inclusion Criteria:
• Patients must be ≥18 years of age.
• Pathologically documented breast cancer that:

  1. is advanced or metastatic

  2. has a history of HER2-low or negative expression by local test, defined as IHC 2+/ISH- or IHC 1+ (ISH- or untested) or HER2 IHC 0 (ISH- or untested)

  3. has HER2-low or HER2 IHC >0 <1+ expression as determined by central HER2 laboratory 

      result established on a tissue sample taken in the metastatic setting

  4. was never previously HER2-positive

  5. is documented HR+ disease in the metastatic setting.

  6. No prior chemotherapy for advanced or metastatic breast cancer.

  7. Has adequate tumor samples for assessment of HER2 status

  8. Must have either:

   a. disease progression within 6 months of starting first line metastatic treatment with an endocrine therapy combined with a CDK4/6 inhibitor or;

   b. disease progression on at least 2 previous lines of endocrine therapy with or without a targeted therapy in the metastatic setting (progression

       of disease within 24 months on adjuvant ET is considered a line of therapy)

  9. Has protocol-defined adequate organ and bone marrow function.

 

Key Exclusion Criteria:
• Ineligible for all options in the investigator’s choice chemotherapy arm
• Uncontrolled intercurrent illness or significant cardiovascular disease
• Active or prior documented ILD/pneumonitis or suspected ILD/pneumonitis that cannot be ruled out by imaging at screening
• Lung-specific intercurrent clinically significant illnesses
• Patients with spinal cord compression or clinically central nervous system metastasis.
