If you are undergoing treatment for breast cancer, then Trodelvy can be an option for specific breast cancers. According to studies, it is more effective in fighting certain types of breast cancers than other available medications and can increase your overall life expectancy.

In this article, we will explore everything you need to know about Trodelvy, including its uses, dosing, side effects, cost, and much more.

What Is Trodelvy?

Trodelvy (sacituzumab govitecan-hziy) is a cancer medicine used to treat two types of breast cancer.

The FDA first approved this drug on April 22, 2020, to treat adults with triple-negative breast cancer. Later, on February 3, 2023, the FDA approved this drug to treat adults with HR-positive, HER2-negative breast cancer (HR+/HER2-) [1].

You can only receive Trodelvy infusions after receiving at least two other treatments. Several studies have shown that this drug can increase the time before your cancer progresses and increase your life expectancy.

This drug works by targeting and binding to a protein present on the surface of the cancer cells, delivering chemotherapy medication into the cancer cells and killing them. This targeted approach also minimizes side effects.

What Is Trodelvy Used To Treat?

Trodelvy is an FDA-approved brand-name cancer medicine. Trodelvy uses include the treatment of the following cancers that have spread locally (locally advanced) or in other parts of the body (metastatic) and cannot be removed by surgery [2]:

Triple-Negative Breast Cancer: Before using Trodelvy, you have to try at least two other treatments, one of which should be for metastatic cancer.

Hormone Receptor-Positive and Human Epidermal Growth Factor Receptor 2-negative (HR+/HER2-) Breast Cancer: Before using Trodelvy, you have to try endocrine-based therapy and at least two other treatments for the metastatic cancer.

How Does Trodelvy Work?

Trodelvy is a cancer medicine that contains an antibody and an anticancer drug called SN-38. It works differently than traditional chemotherapy drugs. Many breast cancer cells have a large amount of protein called Trop-2 on the outside.

The antibody part of Trodelvy infusions targets and attaches to this Trop-2 protein of cancer cells. Once attached, it delivers the anticancer drug SN-38 directly into the cancer cells.

This targeted approach allows this medication to effectively kill the cancer cells while minimizing damage to the normal, healthy cells to reduce side effects [2].

What Are the Clinical Benefits of Trodelvy?

Trodelvy offers significant benefits to certain types of breast cancer patients compared to standard treatment. In a clinical trial involving 529 patients with metastatic or locally advanced triple-negative breast cancer who received two or more prior treatments, Trodelvy was compared to standard chemotherapy treatment. Researchers found that patients who received infusions lived an average of 4.8 months without disease progression.

However, patients who received standard chemotherapy treatment only lived an average of 1.7 months without disease progression. Patients who took Trodelvy lived an average of 11.8 months longer compared to 6.9 months for those who took standard treatment [2].

In another study, Trodelvy was compared to standard chemotherapy treatment in 543 patients with HER2-negative, HR-positive breast cancer who previously had at least two treatments and an endocrine-based therapy.

According to research findings, Trodelvy users lived an average of 5.5 months before disease progression, compared to 4 months for those receiving standard chemotherapy. Those receiving infusions lived an average of 14.4 months longer, while those receiving standard chemotherapy lived 11.2 months longer [2].
