NTRK-TKI (** Vitrakvi (larotrectinib), Rozlytrek (entrectinib) **)
Other Medications
Description
Larotrectinib and entrectinib are used in the treatment of solid tumors with NTRK gene fusions, including colorectal cancer (CRC) that harbors such alterations. These drugs have shown significant clinical activity in patients with advanced or metastatic CRC who have no satisfactory alternative treatments; however, their use is limited to a small subset of patients with specific genetic mutations.
Mechanism of Action
NTRK-TKIs, such as larotrectinib and entrectinib, inhibit the activity of tropomyosin receptor kinases (NTRK1/2/3) by binding to their ATP-binding sites, thereby blocking downstream signaling pathways that promote cell proliferation and survival.
