TRODELVY® (sacituzumab govitecan-hziy) is a prescription medicine used to treat adults with hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative breast cancer that has spread to other parts of the body (metastatic) or cannot be removed by surgery, and who previously received endocrine therapy and at least two additional treatments for metastatic disease. It is not known if TRODELVY is safe and effective in people with moderate or severe liver problems or in children.
Clinical trial results in HR+/HER2- mBC
TRODELVY was tested in a large phase 3 clinical trial
Researchers tested TRODELVY in a phase 3 clinical trial of 543 adults with previously treated* HR+/HER2- mBC comparing TRODELVY to traditional chemotherapy to find out how long people:
*For information on previous treatments, click “Who were the participants?” below.
HER2- = human epidermal growth factor receptor 2-negative, HR+ = hormone receptor-positive, mBC = metastatic breast cancer
- The researchers selected the type of chemo they received
- Types of chemo included eribulin, capecitabine, gemcitabine, or vinorelbine
All patients had been previously diagnosed with HR+/HER2- mBC and had received
- endocrine therapy
- CDK4/6 inhibitor (a type of targeted therapy)
- taxane (a type of chemotherapy)
- at least 2 and no more than 4 prior chemotherapies for metastatic breast cancer
One of the chemotherapies could have been given as a neoadjuvant or adjuvant treatment if recurrence occurred within 12 months.
Endocrine therapy, CDK4/6 inhibitor, and taxane treatments were administered in a neoadjuvant, adjuvant, or metastatic setting.
TRODELVY is an intravenous infusion.
In the clinical trial, patients who were given TRODELVY received 10 mg/kg on days 1 and 8 of a 21-day treatment cycle.
Researchers determined when to stop TRODELVY treatment depending on how patients were responding to and tolerating treatment.

TRODELVY helped patients live longer than traditional chemotherapy
Half of those receiving TRODELVY lived without cancer progression about 38% longer
Traditional chemotherapy = 271 patients
This result is called median progression-free survival (PFS), which is how long a treatment stops the growth or spread of HR+/HER2- mBC in half of the people who take it.
TRODELVY
Half of those who received TRODELVY lived with no sign of cancer progression for 5.5 months.
Traditional chemo
Half of those who received traditional chemo (eribulin, vinorelbine, gemcitabine, or capecitabine) lived with no sign of cancer progression for 4 months.
Half of those receiving TRODELVY lived about 29% longer overall
Traditional chemotherapy = 271 patients
This result is called median overall survival (OS), which is how long half of the people are alive after starting treatment.
TRODELVY
Half of those who received TRODELVY lived for over 1 year (14.4 months).
Traditional chemo
Half of those receiving traditional chemo lived for 11.2 months.
Researchers also studied how long it took before certain quality of life measures worsened
Health-related quality of life (HRQoL) is the way a person feels about their overall physical and mental health over a period of time.
In the clinical trial, researchers focused on HRQoL measures like overall health and quality of life, fatigue, and pain.
Researchers understand that there are significant health-related quality of life (HRQoL) measures for people living with HR+/HER2- mBC that are not commonly addressed.
That’s why they studied how long it took for certain measures of HRQoL to worsen for people receiving TRODELVY compared to traditional chemo.
Patients completed a 30-question survey* about how different measures of HRQoL, like overall health and quality of life, pain, and fatigue, affected them over the past week.
Patients completed this survey at the beginning of the trial and at least 1 other time during the trial.
Patients gave a numeric score to each question.
*The survey used was the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ).
Researchers wanted to find out how much time it took for certain quality of life measures to get worse for patients receiving TRODELVY compared to patients receiving traditional chemo.
Researchers calculated the median† amount of time it took for those scores to get worse by at least 10 points.
Finally, researchers determined if the difference between the median amount of time in the TRODELVY group and the traditional chemo group was statistically significant.‡
†The median is the middle of a set of numbers; in other words, about half of the people in the study experienced these results.
‡To be statistically significant, the difference between 2 groups must be greater than the difference that could happen by chance.
Certain measures of HRQoL took longer to worsen with TRODELVY than traditional chemo
Important to know: Consider these results carefully. The phase 3 trial was an open-label study. This means researchers knew which patients were receiving TRODELVY, and patients also knew which treatment they were receiving. The questionnaire used was not all-inclusive as it did not measure all treatment-related symptoms or how much the symptoms bothered patients. Also, the results shown here may be unrelated to treatment.
Median time until overall health and quality of life got worse
Traditional chemotherapy = 207 patients
Half of those receiving TRODELVY reported it took 1.3 months longer for overall health and quality of life to get worse.
Median time until fatigue got worse
Traditional chemotherapy = 205 patients
Half of those receiving TRODELVY reported it took almost 1 month longer for fatigue to get worse.
Median time until pain got worse
Traditional chemotherapy = 202 patients
Time until pain got worse was similar for both groups. This result was not a statistically significant difference.§
§To be statistically significant, the difference between 2 groups must be greater than the difference that could happen by chance.
