Tisotumab vedotin-tftv (Tivdak – Seagen/Genmab), a tissue factor-directed antibody and microtubule inhibitor conjugate, has received full approval from the FDA for treatment of recurrent or metastatic cervical cancer that progressed on or after chemotherapy. It is the first antibody-drug conjugate to be approved for treatment of cervical cancer. The drug received accelerated approval from the FDA in 2021 for the same indication.

Sacituzumab govitecan-hziy (Trodelvy – Gilead) has been approved for treatment of unresectable locally advanced or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer in adults who received prior endocrine therapy and ≥2 additional systemic therapies for metastatic disease. It was previously approved for treatment-refractory metastatic triplenegative breast cancer and for treatment of locally advanced or metastatic urothelial cancer in adults who received platinum-based chemotherapy and a programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor.

The FDA has approved margetuximab-cmkb (Margenza – MacroGenics), a HER2/neu receptor antagonist, for use in combination with chemotherapy for treatment of metastatic human epidermal growth factor receptor 2 (HER2)-positive breast cancer in adults who received ≥2 prior anti-HER2 regimens, at least one of which was for metastatic disease.

The FDA has approved sacituzumab govitecan-hziy (Trodelvy – Immunomedics), a trophoblast cell-surface antigen-2 (Trop-2)-directed antibody and topoisomerase inhibitor conjugate, for treatment of adults with metastatic triple-negative breast cancer who have received ≥2 prior therapies for metastatic disease. It is the first Trop-2-directed antibody-drug conjugate to become available in the US.

Eribulin mesylate (Halaven – Eisai) has been approved by the FDA for treatment of patients with metastatic breast cancer who have previously received at least 2 chemotherapy regimens for metastatic cancer. Prior therapy should have included an anthracycline and a taxane in either an adjuvant or metastatic setting. Other drugs used to treat anthracycline- and taxane-refractory metastatic breast cancer include capecitabine (Xeloda), gemcitabine (Gemzar, and others) and vinorelbine (Navelbine, and others).

The tables in this article list drugs used for treatment of cancer in the USA and Canada and their major adverse effects. The choice of drugs in Table I is based on the opinions of Medical Letter consultants. Some drugs are listed for indications for which they have not been approved by the US Food and Drug Administration. In some cases, such as elderly patients or those with many co-morbid illnesses, the regimen of choice might not be suitable. For many of the cancers listed, surgery and/or radiation therapy may be the treatment of choice or may also be part of the management.
