Question 3

How does Zydelig work?

Accepted Answer

Mechanism of Action

Zydelig is a type of medication called a kinase inhibitor. It works by interfering with the signals that tell cancer cells to grow and multiply.

The medication specifically targets a protein known as phosphoinositide 3-kinase (PI3K) delta. This protein is found in certain white blood cells called B-cells. In some types of cancer, this protein becomes overactive, causing the B-cells to grow uncontrollably and survive longer than they should.

Interrupt the growth cycle of cancer cells.

Prevent cancer cells from receiving survival signals.

Reduce the overall number of cancer cells in the body.

Males: Men with female partners who are able to become pregnant should use effective birth control during treatment and for at least 3 months after the final dose.

Breastfeeding

Question 10

What is the FDA approval status of Zydelig?

Accepted Answer

FDA Approval and Indications

Zydelig (idelalisib) is approved by the U.S. Food and Drug Administration (FDA) for the treatment of relapsed chronic lymphocytic leukemia (CLL). It is used in combination with rituximab for patients for whom rituximab alone would be considered appropriate therapy. While Zydelig previously held accelerated approvals for follicular lymphoma and small lymphocytic lymphoma, those specific indications were voluntarily withdrawn from the U.S. market by the manufacturer.

Boxed Warning

The FDA has issued a Boxed Warning for Zydelig, which is the most serious type of warning for a medication. This warning alerts healthcare providers and patients to the risk of fatal and serious toxicities, including:

Liver toxicity: Severe and sometimes fatal liver injury.

Diarrhea and colitis: Severe or fatal diarrhea or inflammation of the colon.

Pneumonitis: Serious or fatal inflammation of the lungs.

Intestinal perforation: Fatal or serious tears in the wall of the intestine.

Safety Alerts and Monitoring

The FDA has issued safety communications regarding clinical trials that showed an increased risk of death and serious infections when Zydelig was combined with other cancer treatments. Because of these risks, the FDA recommends that patients be monitored closely for signs of infection and receive preventive medication for specific types of pneumonia during treatment. Healthcare providers are also required to perform regular blood tests to monitor liver function.

Question 11

What should I know about Zydelig and cost?

Accepted Answer

Factors Affecting Cost

The price of Zydelig can vary significantly based on the following:

Dosage: The total cost may be influenced by the strength and quantity of tablets prescribed by your healthcare provider.

Financial Assistance

Because Zydelig is a high-cost specialty medication, there are often programs available to help manage the expense:

Co-pay Assistance: The manufacturer may offer co-pay cards or coupons for patients with commercial insurance to help reduce monthly out-of-pocket costs.

Patient Assistance Programs: For patients who are uninsured or underinsured, non-profit organizations or the drug manufacturer may provide the medication at a lower cost or for free to those who meet specific financial eligibility criteria.
