ESMO 2022 – Key Take-Aways in Breast Cancer

Every fall, the European Society of Medical Oncology (ESMO) hosts their annual conference in Europe. Researchers, oncologists, oncology health professionals, industry representatives, and patient advocates attend to hear updates on the latest research and to attend educational sessions in various tracks related to cancer. This year over 2,000 abstracts were presented at the conference in Paris France September 9-13, 2022.

Among those were the results from the TROPiCS-02 clinical trial: A randomized phase 3 study of sacituzumab govitecan-hziy (SG; TRODELVY®) versus treatment of physician’s choice in patients with hormone receptor-positive/HER2-negative (HR+/HER2-) advanced or metastatic breast cancer. Interim results from this trial were presented earlier in the summer at the 2022 ASCO meeting in Chicago. At that time, data for the clinically important endpoint, overall survival (OS), were immature. An updated readout of the data was presented at ESMO 2022.

SG is an antibody-drug conjugate (ADC) that targets Trop-2, an antigen that is overexpressed on the cell surface of some breast cancer tumor cells, especially in triple-negative breast cancer (TNBC) and is linked to tumor progression and poor prognosis. For more details on how ADC’s work, you can read our June 27 Science Spotlight.

SG first received accelerated approval from the FDA in April 2020[i] and then regular FDA approval in April 2021 for relapsed or refractory metastatic TNBC. This approval was based on the results of the phase III randomized ASCENT trial[ii] which demonstrated a 5.4-month improvement in OS. The drug, however, was shown to cause significant side effects, the most common being nausea, neutropenia, diarrhea, fatigue, anemia, vomiting, alopecia, constipation, rash, decreased appetite, and abdominal pain.

The phase III TROPiCS-02 study evaluated the use of SG in advanced or metastatic HR+/HER2- breast cancer. TROPiCS-02 randomized 543 heavily pretreated patients to either SG or treatment of physician’s choice (TPC) (i.e., capecitabine, vinorelbine, gemcitabine, or eribulin). The primary endpoint was progression-free survival (PFS); the secondary endpoints included OS and safety.

At the first interim analysis of the trial data presented at ASCO 2022, PFS was improved by 1.5 months in SG arm compared with treatment of physician’s choice. Median OS was still immature. With an additional couple of months of follow-up, results presented at ESMO 2022 demonstrated that SG results in an OS benefit of 3.2 months (14.4 months compared to 11.2 months for comparator chemotherapy). However, as presented at ASCO, grade 3 or above treatment-emergent adverse events (TEAEs) were present in 74% and 60% of patients in the SG and TCP arms respectively.

  • SG TEAEs: diarrhea, febrile neutropenia, neutropenia, and neutropenic colitis.
  • TCP TEAEs: febrile neutropenia, pneumonia, nausea, and dyspnea
  • SG arm: 6 deaths during treatment, 1 that was treatment-related

While this drug has demonstrated an OS benefit for heavily pretreated patients with HR+/HER2-, it has not yet received FDA approval though we imagine that will be a matter of time. At a cost of approximately $16,096 per 21-day cycle for a 70-kg (154-lb) person, and with heavy side effects, it may be a choice in the near term for patients with metastatic HR+/HER2- breast cancer with limited options. And while OS is an important endpoint for patients with limited options, having a good quality of life is also important. We continue to demand treatments that don’t present such difficult decisions for patients.
