Does Leukine (sargramostim) cause side effects?
Leukine (sargramostim) is a colony-stimulating factor used to increase the number of white blood cells in patients with low white blood cell counts (neutropenia).
- It is a man-made form of the naturally-occurring protein, granulocyte, macrophage-colony stimulating factor (GM-CSF).
- GM-CSF is produced in the body by the immune system and stimulates the formation of white blood cells, including the granulocyte and the macrophage.
- Granulocytes and macrophages take part in the inflammatory reaction.
- They are responsible for detecting and destroying harmful bacteria and some fungi.
Common side effects of Leukine include:
- stomach pain,
- mild to moderate fever,
- weakness,
- chills,
- headache,
- nausea,
- vomiting,
- diarrhea,
- rash,
- muscle and bone pain.
- shortness of breath,
- weight loss,
- leg and arm swelling, and
- injection site reactions.
Serious side effects of Leukine include:
Drug interactions of Leukine include drugs that may potentiate Leukine's myeloproliferative effects, such as lithium and corticosteroids.
Tell your doctor if you are pregnant or plan to become pregnant before using Leukine; it may harm a fetus. There are no studies to determine if Leukine passes into 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 with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Autologous Peripheral Blood Progenitor Cell (PBPC) And Bone Marrow Transplantation
Studies 301, 302 and 303 enrolled a total of 156 patients after autologous or allogeneic marrow or PBPC transplantation. In these placebo-controlled studies, pediatric and adult patients received once-daily intravenous infusions of Leukine 250 mcg/m² or placebo for 21 days.
In Studies 301, 302, and 303, there was no difference in relapse rate between the Leukine and placebo-treated patients. Adverse reactions reported in at least 10% of patients who received intravenous Leukine or at a rate that was at least 5% higher than the placebo arm are shown in Table 1.

There was no significant difference between the arms in the proportion of patients achieving complete remission (CR; 69% in the Leukine group and 55% in the placebo group).
There was also no significant difference in relapse rates; 12 of 36 patients who received Leukine and five of 26 patients who received placebo relapsed within 180 days of documented CR (p=0.26). The study was not sized to assess the impact of Leukine treatment on response.
Graft Failure
- In a historically controlled study of 86 patients with AML, the Leukine treated group exhibited an increased incidence of weight gain (p=0.007), low serum proteins, and prolonged prothrombin time (p=0.02) when compared to the control group.
- Two Leukine treated patients had progressive increase in circulating monocytes and promonocytes and blasts in the marrow, which reversed when Leukine was discontinued.
- The historical control group exhibited an increased incidence of cardiac events (p=0.018), liver function abnormalities (p=0.008), and neurocortical hemorrhagic events (p=0.025).
- Headache (26%), pericardial effusion (25%), arthralgia (21%), and myalgia (18%) were also reported in patients treated with Leukine in the graft failure study.
Immunogenicity
- As with all therapeutic proteins, there is the potential for immunogenicity with Leukine.
- The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay.
- Additionally, the observed incidence of antibody positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, duration of treatment, concomitant medications, and underlying disease.
- For these reasons, comparison of the incidence of antibodies to sargramostim in the studies described below with the incidence of antibodies in other studies or other products may be misleading.
- In 214 patients with a variety of underlying diseases, neutralizing anti-sargramostim antibodies were detected in 5 patients (2.3%) after receiving Leukine by continuous IV infusion (3 patients) or SC injection (2 patients) for 28 to 84 days in multiple courses (as assessed by GMCSF dependent human cell-line proliferation assay).
- All 5 patients had impaired hematopoiesis before the administration of Leukine, and consequently the effect of the development of antisargramostim antibodies on normal hematopoiesis could not be assessed.
- Antibody studies of 75 patients with Crohn's disease (a disease for which Leukine is not indicated), with normal hematopoiesis and no other immunosuppressive drugs, receiving Leukine daily for 8 weeks by SC injection, showed 1 patient (1.3%) with detectable neutralizing anti-sargramostim antibodies (as assessed by GM-CSF dependent human cell-line proliferation assay).
- In an experimental use trial where Leukine was given for an extended period, 53 patients with melanoma in complete remission (a disease for which Leukine is not indicated) received adjuvant therapy with Leukine 125 mcg/m² once daily (maximum dose 250 mcg) from day 1 to 14 every 28 days for 1 year.
- Serum samples from patients assessed at day 0, 2 weeks, 1 month, and 5 and/or 12 months were tested retrospectively for the presence of anti-sargramostim antibodies.
- Of 43 evaluable patients (having at least 3 timepoint samples post treatment), 42 (97.7%) developed anti-sargramostim binding antibody as assessed by ELISA and confirmed using an immunoprecipitation assay. Of these 42 patients, 41 had sufficient sample and were further tested:
- 34 patients (82.9%) developed anti-sargramostim neutralizing antibodies (as determined by a cell based luciferase reporter gene neutralizing antibody assay);
- 17 (50%) of these patients did not have a sustained pharmacodynamic effect of Leukine by day 155 as assessed by WBC counts.
- This study provided limited assessment of the impact of antibody formation on the safety and efficacy of Leukine.
- Serious allergic and anaphylactoid reactions have been reported with Leukine, but the rate of occurrence of antibodies in such patients has not been assessed.
Postmarketing Experience
The following adverse reactions have been identified during postapproval use of Leukine in clinical trials and/or postmarketing surveillance. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
- Infusion related reactions including dyspnea, hypoxia, flushing, hypotension, syncope and/or tachycardia
- Serious allergic reactions/hypersensitivity, including anaphylaxis, skin rash, urticaria, generalized erythema, and flushing
- Effusions and capillary leak syndrome
- Supraventricular arrhythmias
- Leukocytosis including eosinophilia
- Thromboembolic events
- Pain, including chest, abdominal, back, and joint pain
- Injection site reactions
What drugs interact with Leukine (sargramostim)?
Concomitant Use With Products That Induce Myeloproliferation
- Avoid the concomitant use of Leukine and products that induce myeloproliferation (such as lithium and corticosteroids).
- Such products may increase the myeloproliferative effects of Leukine.
- Monitor patients receiving both Leukine and products that induce myeloproliferation frequently for clinical and laboratory signs of excess myeloproliferative effects.
Summary
Leukine (sargramostim) is a medication prescribed to increase the number of white blood cells in patients with low white blood cell counts (neutropenia). Common side effects of Leukine include stomach pain, mild to moderate fever, weakness, chills, headache, nausea, vomiting, diarrhea, rash, muscle and bone pain, shortness of breath, weight loss, leg and arm swelling, and injection site reactions. Leukine may harm a fetus. There are no studies to determine if Leukine passes into breast milk. Consult your doctor before breastfeeding.

Cancer
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.

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).
-
Neutropenia
Neutropenia is a marked decrease in the number of neutrophils, neutrophils being a type of white blood cell (specifically a form of granulocyte) filled with neutrally-staining granules, tiny sacs of enzymes that help the cell to kill and digest microorganisms it has engulfed by phagocytosis. Signs and symptoms of neutropenia include gum pain and swelling, skin abscesses, recurrent ear and sinus infections, sore mouth, low-grad fever, pneumonia-like symptoms, and pain and irritation around the rectal area. Neutropenia has numerous causes, for example, infections (HIV, TB, mono); medications (chemotherapy); vitamin deficiencies (anemia); bone marrow diseases (leukemias), radiation therapy, autoimmune destruction of neutrophils, and hypersplenism. Treatment of neutropenia depends upon the cause and the health of the patient.
