Question 1

What is Lorlatinib?

Accepted Answer

Lorlatinib is a medication that works by interfering with the growth and spread of cancer cells in the body. It is classified as a kinase inhibitor, which is a type of drug that targets specific proteins involved in cell signaling.

The medication functions by blocking the action of abnormal proteins that tell cancer cells to multiply. By inhibiting these signals, lorlatinib helps to slow or stop the progression of the disease at a molecular level.

Question 3

How does Lorlatinib work?

Accepted Answer

Targeting Abnormal Proteins

Lorlatinib is a type of medication called a kinase inhibitor. It works by identifying and blocking specific proteins, primarily anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1). In some forms of non-small cell lung cancer, these proteins are abnormal and send signals that tell cancer cells to grow and divide uncontrollably.

By attaching to these proteins, lorlatinib interferes with those growth signals. This action helps to slow down or stop the progression of the cancer.

Reaching the Central Nervous System

Lorlatinib is designed to cross the blood-brain barrier, which is a protective membrane that often prevents medications from entering the brain. This capability allows the drug to reach and treat cancer cells that may have spread to the brain or spinal cord.

How to Take This Medication

Lorlatinib is a tablet taken by mouth once daily. It should be taken at the same time every day to ensure the best results. You can take it with or without food.

When taking lorlatinib, keep the following in mind:

Swallow tablets whole. Do not chew, crush, or break them.

Do not use tablets that are broken, cracked, or damaged.

Missed Doses

If you vomit after taking a dose, do not take an additional dose. Take your next dose at the usual time.

Dietary Considerations

Avoid eating grapefruit or drinking grapefruit juice while being treated with lorlatinib, as these can change how the drug works in your body. You should also avoid taking herbal supplements that contain St. John's wort.

Question 9

Is Lorlatinib safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Lorlatinib can cause harm to a fetus. Healthcare providers typically recommend a pregnancy test before starting treatment to ensure the patient is not pregnant. If you are pregnant or planning to become pregnant, it is important to discuss the risks with your doctor.

Patients who can become pregnant should use effective non-hormonal contraception during treatment and for at least 6 months after the final dose. Lorlatinib can interact with hormonal birth control methods, such as pills, patches, or implants, making them less effective. Men with female partners of reproductive potential should use effective contraception during treatment and for 3 months after the last dose.

Breastfeeding

It is unknown if lorlatinib passes into breast milk. Due to the potential for serious side effects in a nursing infant, breastfeeding is not recommended during treatment and for 7 days after the final dose.

Question 11

What is the FDA approval status of Lorlatinib?

Accepted Answer

FDA Approval Status

Lorlatinib is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adults with metastatic non-small cell lung cancer (NSCLC) that is anaplastic lymphoma kinase (ALK)-positive. The medication is used as a first-line treatment or for patients whose cancer has progressed after taking other ALK inhibitors.

The drug first received accelerated approval in November 2018. This initial indication was for patients whose metastatic disease had progressed on crizotinib and at least one other ALK inhibitor, or for those whose disease progressed on alectinib or ceritinib as the first ALK inhibitor therapy. In March 2021, the FDA converted this to a full approval and expanded the indication to include all adults with metastatic ALK-positive NSCLC, regardless of prior treatment history.

Regulatory Requirements

Biomarker Testing: Use of lorlatinib requires confirmation of ALK-positive status using an FDA-approved diagnostic test.

Safety Monitoring: While lorlatinib does not have a Boxed Warning or a Risk Evaluation and Mitigation Strategy (REMS) program, the FDA-approved labeling includes warnings for serious risks including central nervous system (CNS) effects, lipid elevations, atrioventricular block, and interstitial lung disease.

Question 12

What should I know about Lorlatinib and cost?

Accepted Answer

Factors Affecting Cost

The price of lorlatinib can vary based on several factors. Because it is a specialized prescription medication, the final out-of-pocket cost is typically determined by:

Insurance Coverage: Your specific health insurance plan, including your deductible, co-payment, or co-insurance requirements, will significantly impact the cost.

Pharmacy Selection: Lorlatinib may only be available through certain specialty pharmacies rather than standard retail locations. Your healthcare provider or insurance company will often specify which pharmacy you must use.

Brand Name: Lorlatinib is available as the brand-name medication Lorbrena.

Financial Assistance

Patients may be able to reduce their costs through various support options. It is common for manufacturers of specialized oncology drugs to offer patient assistance programs or co-pay cards for eligible individuals. You should consult with your healthcare team or insurance provider to identify available resources that may help manage the cost of treatment.
