Nelarabine is an anti-cancer ("antineoplastic" or "cytotoxic")
chemotherapy drug. This medication is classified as an "antimetabolite". For more
detail, see "How Nelarabine Works" below.
What Nelarabine Is Used For:
- Nelarabine 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
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 Nelarabine Is Given:
- By intravenous (IV) infusion.
- The amount of Nelarabinethat 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 of Nelarabine:
Important things to remember about the side effects of Nelarabine:
- Most people do not experience all of the Nelarabine side
- Nelarabine side effects are often predictable in terms
of their onset and duration.
- Nelarabine side effects are almost always reversible and
will go away after treatment is complete.
- There are many options to help minimize or prevent side
- There is no relationship between the presence or severity
of side effects and the effectiveness of Nelarabine.
The following side effects are common (occurring in
greater than 30%) for patients taking Nelarabine:
- Low blood counts (anemia, neutropenia, thrombocytopenia)
These side effects are less common side effects
(occurring in about 10-29%) of patients receiving Nelarabine:
- Extreme sleepiness
- Peripheral neuropathy
- Shortness of breath
- Muscle aches
- Pleural effusion
Nelarabine 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

- Avoid contact sports or activities that could cause injury.

eat small frequent meals. Sucking on lozenges and chewing gum may also help.
- Keep your bowels moving. Your health care provider may
prescribe a stool softener to help prevent constipation that may be caused by this
- Avoid sun exposure. Wear SPF 15 (or higher) sunblock and
- In general, drinking alcoholic beverages should be kept
to a minimum or avoided completely. You should discuss this with your doctor.

with your doctor before taking it.
Monitoring and Testing While Taking Nelarabine:
You will be checked regularly by your health care professional
while you are taking Nelarabine, 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 Nelarabine 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
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.
Nelarabine 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.
Nelarabine is classified as an adenosine deaminase inhibitor.
