Frequently Asked Questions about ROZLYTREK™ (entrectinib)
Generic Name: entrectinib
Trade Name: ROZLYTREK™
For which conditions is ROZLYTREK™ approved for? ROZLYTREK is indicated for treatment of:
· Adult patients with ROS1-positive metastatic non-small cell lung cancer (NSCLC).
· Adult and patients 12 or older with a neurotrophic tyrosine receptor kinase (NTRK) gene fusion-positive solid tumors who have progressive metastatic disease following treatment and are not surgical candidates.
ROZLYTREK is approved under accelerated approval and continued approval may be contingent on verification of benefit in confirmatory trials.
What is the mechanism of action? ROZLYTREK is a kinase inhibitor. A kinase is a type of protein in the body that helps control cell division. Cancer cells grow in an uncontrolled fashion, and ROZLYTREK works by interfering with the kinase to stop cancer cells from dividing and growing in solid tumors that are NTRK gene fusion-positive or ROS1-positive**.** ROZLYTREK is targeted against several biochemical pathways implicated in the growth and spread of cancer. Specifically, ROZLYTREK is targeted against the TRK A/B/C and ROS1 proteins.
How is ROZLYTREK typically given (administered)? ROZLYTREK is taken orally once daily. A missed dose can be made up unless the next dose is due within 12 hours. If you experience vomiting immediately after taking a dose of ROZLYTREK, take a dose as soon as possible.
How are patients monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with ROZLYTREK. Typically, blood will be drawn before and after treatment to check levels of blood cells and to monitor functions of some organ systems, such as the kidneys, liver and heart. Patients may also undergo physical examinations, scans, or other measures to assess side effects and response to therapy.
