Does Sprycel (dasatinib) cause side effects?
Sprycel (dasatinib) is a kinase inhibitor used to treat chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL).
Kinase inhibitors prevent the growth of tumors by reducing the action of proteins that control cell division, growth, and survival. These proteins are usually present in larger quantities or are more active in cancer cells. By reducing the activity of these proteins, growth and survival of cancer cells are reduced.
Common side effects of Sprycel include
- fluid retention,
- headache,
- diarrhea,
- constipation,
- weakness,
- nausea and vomiting,
- abdominal distention,
- weight changes,
- rash,
- itching,
- chills,
- dizziness, and
- muscle pain.
Serious side effects of Sprycel include
- fever associated with reduced white blood cells,
- reduced platelets,
- reduced blood cell counts,
- infection,
- stomach or intestinal bleeding,
- bleeding in the brain,
- heart failure, and
- fluid in the lungs.
Drug interactions of Sprycel include ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole, and grapefruit juice, because these drugs reduce the breakdown of Sprycel by liver enzymes and increase the blood concentration of Sprycel.
- Dexamethasone, carbamazepine, phenobarbital, rifampin, phenobarbital, and St John's wort decrease the concentration of Sprycel resulting in decreased blood levels and possibly reduced effect.
- Drugs that reduce production of acid in the stomach such as proton pump inhibitors (PPIs) such as omeprazole and H2 blocking drugs such as famotidine reduce the absorption of Sprycel.
- Sprycel increases the blood concentration of simvastatin by reducing the activity of enzymes that break down simvastatin in the liver. This may increase the side effects of simvastatin.
- Sprycel may interact with other drugs that are broken down in a similar way as simvastatin.
Sprycel is harmful to a fetus and should not be used during pregnancy. It is unknown if Sprycel is excreted in breast milk. Consult your doctor before breastfeeding.

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
- The data described below reflect exposure to Sprycel at all doses tested in clinical studies (n=2809), including 324 adult patients with newly diagnosed chronic phase CML, 2388 adult patients with imatinib-resistant or -intolerant chronic or advanced phase CML or Ph+ ALL, and 97 pediatric patients with chronic phase CML.
- The median duration of therapy in a total of 2712 adult patients was 19.2 months (range 0 to 93.2 months).
- In a randomized trial in patients with newly diagnosed chronic phase CML, the median duration of therapy was approximately 60 months.
- The median duration of therapy in 1618 adult patients with chronic phase CML was 29 months (range 0 to 92.9 months).
- The median duration of therapy in 1094 adult patients with advanced phase CML or Ph+ ALL was 6.2 months (range 0 to 93.2 months).

Laboratory Abnormalities
- Myelosuppression was commonly reported in all patient populations. The frequency of Grade 3 or 4 neutropenia, thrombocytopenia, and anemia was higher in patients with advanced phase CML than in chronic phase CML (Tables 11 and 12).
- Myelosuppression was reported in patients with normal baseline laboratory values as well as in patients with pre-existing laboratory abnormalities.
- In patients who experienced severe myelosuppression, recovery generally occurred following dose interruption or reduction; permanent discontinuation of treatment occurred in 2% of adult patients with newly diagnosed chronic phase CML and 5% of adult patients with resistance or intolerance to prior imatinib therapy.
- Grade 3 or 4 elevations of transaminases or bilirubin and Grade 3 or 4 hypocalcemia, hypokalemia, and hypophosphatemia were reported in patients with all phases of CML but were reported with an increased frequency in patients with myeloid or lymphoid blast phase CML. Elevations in transaminases or bilirubin were usually managed with dose reduction or interruption. Patients developing Grade 3 or 4 hypocalcemia during Sprycel therapy often had recovery with oral calcium supplementation.
- Laboratory abnormalities reported in adult patients with newly diagnosed chronic phase CML are shown in Table 11. There were no discontinuations of Sprycel therapy in this patient population due to biochemical laboratory parameters.

- anemia (13% vs 13%).
In the pediatric studies, the rates of laboratory abnormalities were consistent with the known profile for laboratory parameters in adults.

What drugs interact with Sprycel (dasatinib)?
Effect Of Other Drugs On Dasatinib
Strong CYP3A4 Inhibitors
- The coadministration with strong CYP3A inhibitors may increase dasatinib concentrations.
- Increased dasatinib concentrations may increase the risk of toxicity.
- Avoid concomitant use of strong CYP3A4 inhibitors.
- If concomitant administration of a strong CYP3A4 inhibitor cannot be avoided, consider a Sprycel dose reduction.
Strong CYP3A4 Inducers
- The coadministration of Sprycel with strong CYP3A inducers may decrease dasatinib concentrations.
- Decreased dasatinib concentrations may reduce efficacy.
- Consider alternative drugs with less enzyme induction potential.
- If concomitant administration of a strong CYP3A4 inducer cannot be avoided, consider a Sprycel dose increase.
Gastric Acid Reducing Agents
- The coadministration of Sprycel with a gastric acid reducing agent may decrease the concentrations of dasatinib. Decreased dasatinib concentrations may reduce efficacy.
- Do not administer H2 antagonists or proton pump inhibitors with Sprycel.
- Consider the use of antacids in place of H2 antagonists or proton pump inhibitors.
- Administer the antacid at least 2 hours prior to or 2 hours after the dose of Sprycel.
- Avoid simultaneous administration of Sprycel with antacids.
Summary
Sprycel (dasatinib) is a kinase inhibitor used to treat chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL). Common side effects of Sprycel include fluid retention, headache, diarrhea, constipation, weakness, nausea and vomiting, abdominal distention, weight changes, rash, itching, chills, dizziness, and muscle pain. Sprycel is harmful to a fetus and should not be used during pregnancy. It is unknown if Sprycel is excreted in breast milk.

Leukemia
Leukemia is a type of cancer of the blood cells in which the growth and development of the blood cells are abnormal. Strictly speaking, leukemia should refer only to cancer of the white blood cells (the leukocytes) but in practice, it can apply to malignancy of any cellular element in the blood or bone marrow, as in red cell leukemia (erythroleukemia).

What Is the Life Expectancy of a Person With Leukemia?
Leukemia is a group of cancers of the blood affecting the white blood cells. White blood cells are the infection-fighting cells of the body. In adults, leukemia is most common in people older than 55 years, with the average age of diagnosis being 66 years. It is also one of the most common cancers in children and adults younger than 20 years. The survival rate is higher for younger people.

How Does Leukemia Kill?
Leukemia is a cancer of the white blood cells of the bone marrow. Patients with leukemia have an over-production of a particular blood cell type in the body, the white blood cells (cells that fight infection, and provide immunity).

Survival Rate for Acute Lymphoblastic Leukemia
The prognosis depends on the type of leukemia, the extent of the disease, age of the patient, and the general condition of the patient. Some patients can go into complete remission. The average five-year survival rate of leukemia is 60-65%.

Leukemia: Signs, Symptoms, And Complications
Leukemia results when the genetic material (DNA) of a single cell in the bone marrow transforms, this is called a mutation. A mutated cell does not perform body function, but it eats away the nutrition meant for the normal cells.
