Are Kanjinti and Tukysa the Same Thing?

Kanjinti (trastuzumab-anns) and Tukysa (tucatinib) are used to treat HER2-positive breast cancer.

Kanjinti is also used to treat HER2 overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma.

Tukysa is used in combination with trastuzumab and capecitabine to treat adult patients with advanced unresectable or metastatic HER2-positive breast cancer, including patients with brain metastases, who have received one or more prior anti-HER2-based regimens in the metastatic setting.

Kanjinti is a HER2/neu receptor antagonist and Tukysa is a kinase inhibitor.
