For which conditions is this drug approved? TAFINLAR isindicated as a single agent for the treatment of patients with unresectable (unable to be removed with surgery) or metastatic melanoma with BRAF V600E mutation, as detected by an FDA-approved test. TAFINLAR is also indicated in combination with MEKINIST® (trametinib) for the treatment of patients with unresectable or metastatic melanoma with a confirmed BRAF V600E or V600K mutation.
What is the mechanism of action? TAFINLAR is a kinase inhibitor. These drugs work by blocking the action of enzymes called kinases, which are involved in many cell functions, including cell signaling, growth, and division. These enzymes may be too active or found at high levels in some types of cancer cells, and blocking them may help keep cancer cells from growing. Specifically, TAFINLAR targets BRAF V600 kinases, which may be involved in cancer cell growth in metastatic melanoma.
How is TAFINLAR typically given (administered)?TAFINLAR should only be given as a single agent to patients with a BRAF V600E mutation that’s been confirmed through laboratory testing and in combination with MEKINIST in patients with confirmed BRAF V600E or V600K mutation. As a single agent, the recommended dose of TAFINLAR is 150 mg orally twice daily. In combination with MEKINIST, the recommended dose is 2 mg orally once daily. TAFINLAR should be taken at least 1 hour before or at least 2 hours after a meal.
How are patients typically monitored?Patients should be monitored for new malignancies before, after, and during treatment; tumor growth; symptoms of bleeding; blood clotting; heart and eye problems; fever; skin infection; and hyperglycemia (high blood sugar).
What are the common (occur in 20% or more of patients) side effects of treatment with TAFINLAR as a single agent?
What are the common (occur in 20% or more of patients) side effects of treatment with TAFINLAR in combination with MEKINIST?
This is not a complete list of side effects. Some patients may experience other side effects that are not listed here. Patients may wish to discuss with their physician the other less common side effects of this drug, some of which may be serious.
Some side effects may require medical attention. Other side effects do not require medical attention and may go away during treatment. Patients should check with their physician about any side effects that continue or are bothersome.
What can patients do to help alleviate or prevent discomfort and side effects? Tell your doctor if you have or have had any medical condition, with special attention to the following:
Take TAFINLAR one time a day exactly as your healthcare provider tells you to take it. Swallow capsules whole; don’t open, crush, or break them. Do not change your dose or stop TAFINLAR unless your healthcare provider tells you to do so. If you miss a dose, take it as soon as you remember. If it is within 12 hours of your next scheduled dose, skip the missed dose and take the next dose at your regular time. If you take too much TAFINLAR, call your healthcare provider or go to the nearest hospital emergency room right away.
Are there any special precautions patients should be aware of before startingtreatment? TAFINLAR can harm your unborn baby, and women who are able to become pregnant should use effective birth control during treatment and for two weeks after stopping treatment with TAFINLAR alone or for four months when taking TAFINLAR in combination with MEKINIST.Be aware that birth control using hormones (such as birth control pills, injections, or patches) may not work as well with TAFINLAR, so use a non-hormonal effective method of birth control. Tell you doctor if you are breastfeeding or plan to breastfeed; because it is not known if TAFINLAR passes into your breast milk, you should not take this drug while breastfeeding.
When should patients notify their physician?
Tell your doctor if you experience any side effects that bother you or don’t go away. Also call your healthcare provider right away if:
