Farydak®


Generic Name: Panobinostat

Farydak ® is the trade name for the generic drug panobinostat. In some cases, health care professionals may use the generic name panobinostat when referring to the trade drug name Farydak®.

Drug Type:

Farydak ® is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. Farydak® is classified as a "Histone Deacetylase (HDAC) Inhibitor". For more detail, see How Farydak® Works below.

What Farydak Is Used For:

Farydak ®, in combination with bortezomib and dexamethasone, is indicated for the treatment of patients with multiple myeloma who have received at least 2 prior regimens, including bortezomib and an immunomodulatory agent.

Note: If a drug has been approved for one use, physicians may elect to use this same drug for other problems if they believe it may be helpful.

How Farydak Is Given:

  • Farydak ® is a pill, taken by mouth. It is taken orally, once every other day for 3 doses per week (on Days 1, 3, 5, 8, 10, and 12) of Weeks 1 and 2 of each 21 day cycle for 8 cycles. It can be taken with or without food. Your doctor may alter this dosing schedule depending upon side effects from this treatment.
  • Take Farydak® exactly as prescribed. Take 1 time on each scheduled day at about the same time.
  • Swallow Farydak® capsules whole with a full glass of water. Do not crush, dissolve or open capsules.
  • Do not change your dose or stop Farydak® unless your health care provider tells you to.
  • If you miss a dose, take it as soon as you remember. If your next dose is within 12 hours, skip the missed dose and take the next dose at your regular time.
  • If vomiting occurs, you should not repeat the dose but take the next usual scheduled dose.
  • Do not take more than 1 dose of Farydak® at one time. Call your health care provider right away if you take too much.
  • Avoid skin contact with the powder in the Farydak® capsules. If you accidently get powder from the Farydak® capsule on your skin, wash the area with soap and water. If you accidentally get the powder in your eyes, flush your eyes with water.
  • Avoid eating star fruit, pomegranate or pomegranate juice, and grapefruit or grapefruit juice while takingFarydak®. These foods may affect the amount of Farydak® in your blood.

The amount of Farydak ® that you will receive depends on many factors, including your general health or other health problems, and the type of cancer or condition you have. Your doctor will determine your exact dosage and schedule.

Monitoring and Testing:

You will be checked regularly by your doctor while you are taking Farydak®, to monitor side effects and check your response to therapy. Periodic blood work will be obtained to monitor your complete blood count (CBC) as well as the function of other organs (such as your kidneys and liver) will also be ordered by your doctor.

How Farydak Works:

Cancerous tumors are characterized by cell division, which is no longer controlled as it is in normal tissue. "Normal" cells stop dividing when they come into contact with like cells, a mechanism known as contact inhibition. Cancerous cells lose this ability. Cancer cells no longer have the normal checks and balances in place that control and limit cell division. The process of cell division, whether normal or cancerous cells, is through the cell cycle. The cell cycle goes from the resting phase, through active growing phases, and then to mitosis (division).

The ability of chemotherapy to kill cancer cells depends on its ability to halt cell division. Usually, the drugs work by damaging the RNA or DNA that tells the cell how to copy itself in division. If the cells are unable to divide, they die. The faster the cells are dividing, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce cell suicide (self-death or apoptosis).

Chemotherapy drugs that affect cells only when they are dividing are called cell-cycle specific. Chemotherapy drugs that affect cells when they are at rest are called cell-cycle non-specific. The scheduling of chemotherapy is set based on the type of cells, rate at which they divide, and the time at which a given drug is likely to be effective. This is why chemotherapy is typically given in cycles.

Chemotherapy is most effective at killing cells that are rapidly dividing. Unfortunately, chemotherapy does not know the difference between the cancerous cells and the normal cells. The "normal" cells will grow back and be healthy but in the meantime, side effects occur. The "normal" cells most commonly affected by chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea, and/or hair loss. Different drugs may affect different parts of the body.

Farydak ® is a Histone Deacetylase (HDAC) Inhibitor. Histone Deacetylase is an enzyme that is normally present in the cells. In some cancer cells, there is an overexpression of HDACs. It is believed that inhibition of the HDAC activity causes cell cycle arrest and cell death. Farydak® works by inhibiting the activity of enzymes, known as histone deacetylases (HDACs). This process may slow the over-development of plasma cells in multiple myeloma patients or cause cancer cells to die. Farydak® shows more cytotoxicity towards tumor cells compared to normal cells. It works best when combined with drugs like bortezomib (Velcade).
