Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
Key

* 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 the central 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.
* No prior chemotherapy for advanced or metastatic breast cancer.
* Has adequate tumor samples for assessment of HER2 status
* Must have either:

1. disease progression within 6 months of starting first line metastatic treatment with an endocrine therapy combined with a CDK4/6 inhibitor or
2. disease progression on at least 2 previous lines of endocrine therapy with or without a targeted therapy in the metastatic setting. Of note with regards to the =2 lines of previous ET requirement: disease recurrence while on the first 24 months of starting adjuvant ET, will be considered a line of therapy; these patients will only require 1 line of ET in the metastatic setting.
* Has protocol-defined adequate organ and bone marrow function

Key

Key exclusion criteria
* Ineligible for all options in the investigator's choice chemotherapy arm

* Patients with spinal cord compression or clinically active central nervous system metastases
* Prior randomization or treatment in a previous trastuzumab deruxtecan study regardless of treatment arm assignment
* Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study during the follow up period of a prior interventional study (prescreening for this study while a patient is on treatment in another clinical study is acceptable)
