Drug type: IL-11 is a biologic response modifier. IL-11

What This Drug Is Used For:
- Oprelvekin is used to stimulate the bone marrow to produce platelets in order to
prevent low platelets that may be caused by chemotherapy. Platelets are blood cells
that allow the blood to clot, and prevent bleeding.
- Oprelvekin may be given to decrease the need for platelet transfusions.
- Oprelvekin is not indicated for myeloid malignancies (diseases that start in the
bone marrow such as leukemia).
- Oprelvekin is a support medication. It does not treat cancer.
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:
- Oprelvekin is given by subcutaneous (the layer between the skin and muscle).
- Oprelvekin is usually given 6-24 hours after chemotherapy.
- Oprelvekin is generally given on a daily basis. The number of days you receive
oprelvekin will be prescribed by your doctor.
- You may be taught to give these shots to yourself once a day after chemotherapy,
or they may be given to you by another healthcare provider.
- The amount of oprelvekin 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
Important things to remember about the side effects of oprelvekin:
- 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 IL-11:
- Swelling (water retention - most common in the hands, feet and ankles)
- Nausea and vomiting
- Mouth sores
- Shortness of breath
These side effects are less common side effects (occurring in about 10-29%)
of patients receiving IL-11:
- Rapid heart beat/palpitations (see heart problems)
- Insomnia (see sleep problems)
- Rhinitis/pharyngitis (see cold symptoms)
- Conjuctival infection (see eye problems)
- Bone or joint pain
- Temporary anemia (low red blood count - will resolve on it's own within a week after
oprevelkin is discontinued).
A serious, but very uncommon side effect of oprelvekin is "capillary leak
syndrome" or "vascular leak syndrome." Capillary leak syndrome is a potentially
serious disease in which fluids within the vascular system (veins and capillaries)
leaks into the tissue outside the bloodstream. This results in low blood pressure
and poor blood flow to the internal organs. Capillary leak syndrome is characterized
by the presence of 2 or more of the following 3 symptoms; low blood pressure, swelling,
and low levels of protein in the blood. Your doctor will monitor these things
carefully while you are taking oprevelkin. You should notify your doctor
immediately if you notice dizziness (especially when changing position), sudden
swelling or rapid weight gain, little or no urine output (for 8-12 hours), shortness
of breath, difficulty breathing, irregular heart beats, or chest pain.
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:

Monitoring and Testing:
You will be checked regularly by your health care professional while you are taking
oprelvekin, 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:
In the body's bone marrow (the soft, sponge-like material found inside bones) blood
cells are produced. There are three major types of blood cells; white blood
cells, which fight infection; red blood cells, which carry oxygen to and remove
waste products from organs and tissues; and platelets, which enable the blood to
clot. Cancer treatments such as chemotherapy and radiation therapy can effect
these cells which put a person at risk for developing infections, anemia and bleeding
problems. Colony-stimulating factors and growth factors are substances that
stimulate the production of blood cells and promote their ability to function.
They do not directly affect tumors but through their role in stimulating blood cells
they can be helpful as support of the persons immune system during cancer treatment.
Oprelvekin is a cytokine that stimulates the production, maturation and activation
of platelets. In patients receiving chemotherapy, oprelvekin can accelerate the
return of platelets to normal levels, reducing the thrombocytopenic (low platelet)
phase (the time in which people are most susceptible to bleeding), and decrease
the need for platelet transfusions.
