In the article the authors inform: “Sacituzumab govitecan (Trodelvy®) is an antibody drug conjugate (ADC) of a humanized anti-TROP2 monoclonal antibody (mAb), linked to SN-38 — the active metabolite of the anti-cancer drug irinotecan and a potent inhibitor of topoisomerase 1.
Key Points:
- In the article the authors inform: “Sacituzumab govitecan (Trodelvy®) is an antibody drug conjugate (ADC) of a humanized anti-TROP2 monoclonal antibody (mAb), linked to SN-38 — the active metabolite of the anti-cancer drug irinotecan and a potent inhibitor of topoisomerase 1.
- Sacituzumab govitecan has been remarkably effective in many clinical trials and is FDA-approved for patients with metastatic triple-negative breast cancer (TNBC) and pre-treated HR+/ HER2- metastatic breast cancer.
- Hence, sacituzumab govitecan likely acts as a simple prodrug of systemic SN-38 as well as an ADC.
- The authors posit that a long-acting SN-38, such as ProLynx PLX038, should be an efficacious and less toxic prodrug of systemic SN-38 than sacituzumab govitecan, and could serve as a therapy for certain forms of resistance mechanisms to sacituzumab govitecan.
