Arranon ®
(AIR-ra-non)
Generic name: nelarabine
Trade name: Arranonâ
Arranon is the trade name for the drug nelarabine. In some cases, health care professionals may use the trade name Arraron when referring to the generic drug name nelarabine.
Drug type: Arranon is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. This medication is classified as an "antimetabolite". (For more detail, see "How this drug works" section below.)
What this drug is used for:
- Arranon is used to treat T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LBL) whose disease has not responded to or has relapsed following treatment with at least two chemotherapy regimens.
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 this drug is given:
- By intravenous (IV) infusion.
- The amount of nelarabine that you will receive depends on many factors, including your height and weight, your general health or other health problems, and the type of cancer or condition being treated. Your doctor will determine your dose and schedule.
Side effects:
Important things to remember about the side effects of Arranon:
- Most people do not experience all of the side effects listed.
- Side effects are often predictable in terms of their onset and duration.
- Side effects are almost always reversible and will go away after treatment is complete.
- There are many options to help minimize or prevent side effects.
- There is no relationship between the presence or severity of side effects and the effectiveness of the medication.
The following side effects are common (occurring in greater than 30%) for patients taking nelarabine:
- Low blood counts (anemia, neutropenia, thrombocytopenia)
- Nausea
- Fatigue
These side effects are less common side effects (occurring in about 10-29%) of patients receiving nelarabine:

Arranon may cause serious nervous system problems including: extreme sleepiness, numbness and tingling in the hands, fingers, feet or toes (peripheral neuropathy). Also reported rarely; seizures, coma, weakness and paralysis.
Not all side effects are listed above. Some that are rare (occurring in less than 10% of patients) are not listed here. However, you should always inform your health care provider if you experience any unusual symptoms.
When to contact your doctor or health care provider:
Contact your health care provider immediately, day or night, if you should experience any of the following symptoms:
- Fever of 100.5 F (38 C) or higher, chills (possible signs of infection).
- Seizures, confusion, extreme sleepiness.
The following symptoms require medical attention, but are not an emergency. Contact your health care provider within 24 hours of noticing any of the following:
- Nausea (interferes with ability to eat and unrelieved with prescribed medication).
- Vomiting (vomiting more than 4-5 times in a 24 hour period).
- Diarrhea (4-6 episodes in a 24-hour period).
- Extreme fatigue (unable to carry on self-care activities).
- Constipation unrelieved by laxative use.
- Numbness and tingling in the hands, fingers, feet or toes
- Problems with fine motor skills such as buttoning clothes
- Unsteady while walking or increased tripping while walking
- Weakness when getting out of a chair or walking up stairs
- Swelling of the feet or ankles. Sudden weight gain.
Always inform your health care provider if you experience any unusual symptoms.
Precautions:
Self-care tips:
Monitoring and testing:
You will be checked regularly by your health care professional while you are taking Arranon, to monitor side effects and check your response to therapy. Periodic blood work 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 this drug 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.
Arranon belongs to the class of chemotherapy drugs called antimetabolites. Antimetabolites are very similar to normal substances within the cell. When the cells incorporate these substances into the cellular metabolism, they are unable to divide. Antimetabolites are cell-cycle specific. They attack cells at very specific phases in the cycle. Antimetabolites are classified according to the substances with which they interfere. Arranon is classified as an adenosine deaminase inhibitor.
