Question 1

What is selumetinib?

Accepted Answer

Selumetinib is a type of medication called a kinase inhibitor. It works by blocking the action of specific proteins, known as MEK1 and MEK2, which are involved in the signaling pathways that instruct cells to grow and multiply.

By targeting these specific pathways, the medication helps to regulate and slow the growth of certain types of tumors. This targeted approach focuses on the underlying biological mechanisms that contribute to the development of these growths.

Question 2

What is selumetinib used for?

Accepted Answer

Selumetinib is used to treat neurofibromatosis type 1 with plexiform neurofibromas .

Question 3

How does selumetinib work?

Accepted Answer

Mechanism of Action

Selumetinib belongs to a class of medications known as kinase inhibitors. It works by targeting and blocking the activity of proteins called mitogen-activated protein kinase (MEK) 1 and 2.

These MEK proteins are part of a signaling pathway in the body that controls how cells grow and multiply. In people with neurofibromatosis type 1 (NF1), this pathway is often overactive due to a genetic mutation. This overactivity can cause cells to grow uncontrollably, leading to the development of tumors called plexiform neurofibromas.

By inhibiting MEK 1 and 2, selumetinib helps to:

Interfere with the signals that tell tumor cells to grow.

Slow down or stop the progression of plexiform neurofibromas.

Potentially shrink existing tumors that cannot be removed by surgery.

Accepted Answer

How to Take Selumetinib

Selumetinib is taken by mouth as a capsule. It is usually taken twice daily, with doses spaced evenly apart. This medication must be taken on an empty stomach. You should avoid eating for a period of time before and after each dose as instructed by your healthcare provider.

Swallow the capsules whole with water. Do not chew, crush, dissolve, or open the capsules. If you or your child have difficulty swallowing the capsules whole, consult your healthcare provider.

Missed Dose

If you miss a dose, take it as soon as you remember. However, if a significant amount of time has passed since the scheduled dose, skip the missed dose and take the next dose at the regular time. Do not take an extra dose to make up for a missed one.

Administration Tips

Follow the dosing schedule exactly as prescribed.

Keep the capsules in their original container to protect them from moisture.

If vomiting occurs after taking a dose, do not take an additional dose; simply wait until the next scheduled time.

Question 9

Is selumetinib safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Selumetinib can cause harm to a fetus when administered to a pregnant woman. Healthcare providers typically require a pregnancy test for individuals of reproductive potential before starting this medication to ensure they are not pregnant.

Contraception Requirements

Because of the risks to a developing fetus, specific precautions are recommended for both men and women:

Females: Those who can become pregnant should use effective birth control during treatment and for at least one week after the final dose.

Males: Men with female partners who can become pregnant should use effective contraception during treatment and for at least one week after the final dose.

Breastfeeding

It is not known whether selumetinib passes into human breast milk. Due to the potential for serious side effects in a nursing infant, it is advised that individuals do not breastfeed while taking selumetinib and for one week after the last dose. Patients should discuss feeding options with their healthcare provider.

Question 10

What forms and strengths does selumetinib come in?

Accepted Answer

Selumetinib is available in the following form:

Oral Capsule: This medication is taken by mouth. The capsules should be swallowed whole with water and must not be chewed, dissolved, or opened.

Question 11

What is the FDA approval status of selumetinib?

Accepted Answer

FDA Approval Status

Selumetinib was first approved by the U.S. Food and Drug Administration (FDA) in April 2020. It was the first drug therapy specifically approved to treat neurofibromatosis type 1 (NF1), a genetic disorder that causes tumors to grow on nerves.

Approved Indications

The FDA has approved selumetinib for the following populations:

Pediatric patients 2 years of age and older with NF1 who have symptomatic, inoperable plexiform neurofibromas (PN).

Adult patients with NF1 who have symptomatic, inoperable PN.

Regulatory Designations

Because it addressed an unmet medical need for a rare condition, selumetinib received several special regulatory statuses during its development and review, including:

Orphan Drug designation

Breakthrough Therapy designation

Rare Pediatric Disease designation

Priority Review

These designations are intended to expedite the development and review of drugs that treat serious conditions or provide significant improvements over existing therapies.

Question 12

What should I know about selumetinib and cost?
