Sacituzumab Govitecan-hziy: An Antibody-Drug Conjugate for the Treatment of Refractory, Metastatic, Triple-Negative Breast Cancer

Ann Pharmacother. 2021 Jul;55(7):921-931. doi: 10.1177/1060028020966548. Epub 2020 Oct 17.


Objective: To review the pharmacology, efficacy, and safety of sacituzumab govitecan (-hziy; IMMU-132, Trodelvy) for patients with metastatic triple-negative breast cancer (mTNBC) who have received at least 2 prior therapies for metastatic disease.

Data sources: A literature search was conducted utilizing PubMed and MEDLINE databases, applicable published abstracts, and ongoing studies from between January 1, 1981, and September 3, 2020. Keywords included sacituzumab govitecan (-hziy), IMMU-132, Trop-2 (trophoblast cell-surface antigen 2), and TACSTD2.

Study selection and data extraction: All English-language trials involving sacituzumab govitecan for mTNBC were included and discussed.

Data synthesis: Sacituzumab govitecan is an antibody-drug conjugate targeted for Trop-2 and conjugated to the topoisomerase-1 inhibitor SN-38. It was granted accelerated Food and Drug Administration approval based on a phase I/II single-arm, multicenter study (n = 108), which reported an overall response rate of 33.3% and median duration of response of 7.7 months (95% CI = 4.9-10.8 months). Common adverse reactions include nausea, neutropenia, diarrhea, fatigue, anemia, vomiting, alopecia, constipation, rash, decreased appetite, abdominal pain, and respiratory infection. A confirmatory, randomized phase III clinical trial is ongoing (NCT02574455).

Relevance to patient care and clinical practice: This review covers the efficacy, safety, and clinical use of sacituzumab govitecan, a third-line drug with activity in mTNBC.

Conclusion: Sacituzumab govitecan is a novel targeted treatment with promising activity in mTNBC.

Keywords: Trodelvy; Trop-2; antibody-drug conjugate; sacituzumab govitecan; triple-negative breast cancer.
