Question 1

What is Acalabrutinib?

Accepted Answer

Acalabrutinib is a Bruton's tyrosine kinase (BTK) inhibitor that works by blocking the action of an abnormal protein that signals cancer cells to multiply. By targeting these specific proteins, the medication helps to disrupt the life cycle of the cancer cells.

This mechanism of action is designed to slow the progression of the disease at a cellular level. It belongs to a broader category of medications known as antineoplastic agents.

Question 2

Mantle cell lymphoma

Chronic lymphocytic leukemia

Small lymphocytic lymphoma

Question 3

How does Acalabrutinib work?

Accepted Answer

Mechanism of Action

Acalabrutinib is a type of targeted therapy known as a Bruton tyrosine kinase (BTK) inhibitor. It works by interfering with the signals that allow certain cancer cells to grow and multiply.

In the body, BTK is a protein that plays a key role in the development and survival of B-cells, which are a type of white blood cell. In some blood cancers, the B-cells become abnormal and multiply uncontrollably because the BTK protein is constantly sending growth signals.

Acalabrutinib works by binding to the BTK protein and blocking its activity. By shutting down these signals, the medication helps to:

Inhibit cell growth: It prevents the cancerous B-cells from dividing and increasing in number.

Reduce cancer spread: It makes it harder for cancer cells to migrate and survive in different parts of the body.

Induce cell death: Without the necessary survival signals from BTK, the cancerous cells may eventually die.

Question 9

Is Acalabrutinib safe during pregnancy and breastfeeding?

Accepted Answer

There are no adequate studies on the use of acalabrutinib in pregnant women to determine drug-associated risks. However, based on findings from animal studies, this medication may cause harm to a developing fetus when administered during pregnancy. Healthcare providers typically discuss the potential risks to the fetus if the medication is used during pregnancy.

Key considerations for individuals of reproductive potential include:

Pregnancy Testing: Healthcare providers may verify pregnancy status in females of reproductive potential before starting treatment.

Contraception: Individuals who can become pregnant are usually advised to use effective birth control during treatment and for at least one week after the final dose of acalabrutinib.

It is not known whether acalabrutinib or its metabolites are present in human breast milk. There is also no information regarding the effects of the drug on a breastfed child or on milk production. Because of the potential for serious adverse reactions in a nursing infant, healthcare providers generally advise women not to breastfeed during treatment and for at least two weeks after the last dose.

Accepted Answer

FDA Approval History

Acalabrutinib received its initial FDA approval in October 2017. It was originally authorized for the treatment of adults with mantle cell lymphoma who had already received at least one prior therapy. Since its initial approval, the FDA has expanded the authorized uses of the medication to include additional conditions and treatment combinations.

Approved Indications

Acalabrutinib is currently FDA-approved for the following indications:

Mantle Cell Lymphoma (MCL): It is approved for adults who have received at least one prior therapy. In 2024, the FDA also approved its use in combination with bendamustine and rituximab for adults with previously untreated MCL.

Chronic Lymphocytic Leukemia (CLL): It is approved for the treatment of adults with CLL, including those who have not been treated before and those whose cancer has returned or did not respond to previous treatment.

Small Lymphocytic Lymphoma (SLL): It is approved for the treatment of adults with SLL, including both previously untreated and relapsed or refractory cases.

Question 12

What should I know about Acalabrutinib and cost?

Accepted Answer

Factors Influencing Cost

Several factors determine the final price you may pay for acalabrutinib:

Insurance Coverage: Most private insurance plans and Medicare Part D provide coverage for acalabrutinib. However, the amount you pay out-of-pocket will depend on your plan's specific deductible, copayment, or coinsurance requirements.

Specialty Pharmacy Requirements: Acalabrutinib is often classified as a specialty medication. It may not be available at all local pharmacies and may need to be ordered through a specialty pharmacy, which can affect billing and delivery.

Dosage and Treatment Length: The total cost is influenced by the strength of the medication and how long your healthcare provider determines you need to remain on the therapy.

Insurance and Prior Authorization

Because acalabrutinib is a high-cost specialty drug, many insurance companies require a process called prior authorization. This means your doctor must provide documentation to your insurance provider to confirm that the medication is medically necessary before the plan will agree to cover the cost.

Financial Assistance Options

For patients who have difficulty affording their medication, there are several potential avenues for financial support:

Manufacturer Assistance: The drug manufacturer may offer patient assistance programs or copay cards for eligible patients with commercial insurance to help lower out-of-pocket expenses.

Non-Profit Organizations: Some independent foundations provide grants or financial aid to help patients cover the costs of cancer treatments and related expenses.

Government Programs: Patients with limited income may qualify for Extra Help through Medicare or other state-funded programs to assist with prescription drug costs.

It is advisable to consult with your healthcare team, a social worker, or a specialty pharmacist to identify the most appropriate financial resources for your situation.
