Question 1

What is Osimertinib?

Accepted Answer

Osimertinib is a type of medication known as a kinase inhibitor. It functions by blocking the action of specific abnormal proteins that signal cancer cells to multiply and divide.

By targeting these proteins, the medication helps to slow or stop the progression of tumors. It is designed to focus on specific molecular pathways that contribute to the development of cancer.

Question 2

What is Osimertinib used for?

Accepted Answer

Osimertinib is used to treat epidermal growth factor receptor mutation-positive non-small cell lung cancer .

Question 3

How does Osimertinib work?

Accepted Answer

Targeting Cancer Growth

Osimertinib is a type of medication known as a kinase inhibitor. It is designed to treat non-small cell lung cancer that has specific genetic mutations in a protein called epidermal growth factor receptor (EGFR).

In certain types of lung cancer, the EGFR protein is mutated, acting like a switch that is stuck in the "on" position. This sends constant signals to the cancer cells to divide and spread throughout the body. Osimertinib works by interfering with this process in the following ways:

Binding to mutated proteins: The medication attaches to the mutated EGFR proteins on the surface of the cancer cells.

Blocking signals: Once attached, it blocks the chemical signals that tell the cancer cells to grow and survive.

Slowing progression: By cutting off these growth signals, the drug helps to slow down or stop the spread of the cancer and may help shrink tumors.

This medication is specifically effective against certain mutations, such as exon 19 deletions and exon 21 L858R mutations. It is also designed to target the T790M mutation, which is a specific change that can develop in cancer cells and make them resistant to other similar treatments.

and others

Always consult with a healthcare professional about potential side effects.

Question 7

What drug class is Osimertinib?

Accepted Answer

Osimertinib belongs to the EGFR tyrosine kinase inhibitor drug class.

Question 8

What is the dosage of Osimertinib and how do I take it?

Accepted Answer

How to Take

Osimertinib is taken by mouth once a day. It is best to take it at the same time each day. You may take the medication with or without food.

Swallow the tablet whole with water. Do not crush, chew, or break the tablet before swallowing.

Instructions for Swallowing Difficulties

If you have trouble swallowing the tablet whole, you may mix it with water using the following steps:

Place the tablet in a glass containing a small amount of non-carbonated water. Do not use any other liquids.

Stir the tablet until it breaks into very small pieces. Note that the tablet will not dissolve completely.

Drink the mixture immediately.

To ensure you have taken the full dose, add more water to the glass, swirl it, and drink it right away.

Missed Dose

If you miss a dose of osimertinib, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take two doses at once to make up for a missed one.

Question 9

Is Osimertinib safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Osimertinib may cause fetal harm when administered to a pregnant woman. Animal studies have shown that the medication can lead to pregnancy loss or developmental issues. Individuals who are pregnant or planning to become pregnant should discuss the potential risks and benefits with their healthcare provider before starting treatment.

Contraception Requirements

Because of the risk to a developing fetus, healthcare providers typically recommend strict contraception measures:

For females: Use effective birth control during treatment and for at least 6 weeks after the final dose of osimertinib.

For males: Men with female partners who could become pregnant should use effective birth control during treatment and for at least 4 months after the final dose.

Breastfeeding

It is not known whether osimertinib passes into human breast milk. Due to the potential for serious side effects in a nursing infant, breastfeeding is not recommended during treatment. Patients are typically advised to wait at least 2 weeks after their last dose of osimertinib before resuming breastfeeding.

Question 10

What forms and strengths does Osimertinib come in?

Accepted Answer

Osimertinib is available in the following dosage form:

Oral Tablet: This medication is taken by mouth.

The tablets are typically swallowed whole. For individuals who have difficulty swallowing tablets, the medication may be prepared as a liquid mixture by dispersing the tablet in water, following specific medical instructions provided by a healthcare professional.

Question 11

What is the FDA approval status of Osimertinib?

Accepted Answer

FDA Approval and Indications

Osimertinib was first approved by the U.S. Food and Drug Administration (FDA) in 2015. It is indicated for the treatment of adult patients with non-small cell lung cancer (NSCLC) that tests positive for specific epidermal growth factor receptor (EGFR) mutations.

Current approved uses include:

Adjuvant Therapy: Treatment after complete tumor removal in patients with early-stage NSCLC whose tumors have EGFR exon 19 deletions or exon 21 L858R mutations.

Stage III NSCLC: Treatment for patients with locally advanced, unresectable Stage III NSCLC whose disease has not progressed following platinum-based chemotherapy and radiation, and whose tumors have specific EGFR mutations.

First-line Metastatic Treatment: Initial treatment for patients with metastatic NSCLC that has EGFR exon 19 deletions or exon 21 L858R mutations.

T790M Mutation-Positive NSCLC: Treatment for patients with metastatic NSCLC who have the EGFR T790M mutation and whose disease has worsened during or after treatment with other EGFR tyrosine kinase inhibitor (TKI) medicines.

Biomarker Testing

The FDA requires the use of an FDA-approved test to confirm the presence of specific EGFR mutations before starting treatment with osimertinib. This ensures the medication is appropriate for the patient's specific type of cancer.

Regulatory Requirements

There are currently no Boxed Warnings or Risk Evaluation and Mitigation Strategies (REMS) associated with osimertinib. However, it remains under standard FDA monitoring for safety and efficacy.

Question 12

What should I know about Osimertinib and cost?

Accepted Answer

Osimertinib is a prescription medication, and its price can vary significantly based on several factors related to insurance and pharmacy services.

Insurance and Out-of-Pocket Costs

For most patients, the cost of osimertinib is determined by their health insurance provider. Factors that influence the final price include:

The specific coverage levels of the insurance plan.

Applicable copayments or coinsurance amounts.

Whether the medication is covered under the plan's pharmacy or medical benefits.

Patients should contact their insurance company directly to confirm coverage details and any requirements for prior authorization.

Obtaining the Medication

As a specialized treatment for non-small cell lung cancer, osimertinib is typically obtained through specific pharmacy channels. Healthcare providers and pharmacists can provide guidance on the prescription process and help patients understand the costs associated with their specific treatment regimen. Patients may also inquire with their healthcare team about potential financial assistance programs that may be available to help manage out-of-pocket expenses.
