Bayer Announces Availability of Reformulated Liquid Leukine(R)EDTA removed from product
WAYNE, N.J., May 19 (HSMN NewsFeed) -- Bayer HealthCare Pharmaceuticals Inc. announced today that a reformulation of the liquid Leukine® (sargramostim) 500 mcg vial has been approved by the United States Food and Drug Administration (FDA) and is now available for patients and physicians in the U.S. The new formulation does not contain EDTA (edetate disodium), which was in the product's liquid 500 mcg vial manufactured from January 2006 to January 2008.
"The reintroduction of liquid sargramostim without EDTA is welcome news to oncologists and hematologists," said Mark Heaney, MD, PhD, Associate Attending Physician, Memorial Sloan-Kettering Cancer Center, New York, NY, who has studied the biology of the receptor of this drug for more than a decade. "Sargramostim has an important role in reducing life-threatening infections and early death due to infections among older adults (> 55 years of age) with acute myelogenous leukemia (AML). Further, sargramostim is an important therapy in cancer supportive care and has a proven survival benefit in patients experiencing bone marrow transplant failure or engraftment delay."
In January 2008, Bayer withdrew the previously marketed liquid Leukine 500 mcg vial from the U.S. market in order to reformulate it to eliminate EDTA in light of an increase in spontaneous reporting of certain labeled adverse events, including syncope (fainting). The timing of increased reporting of these adverse events coincided with the change in the formulation of liquid Leukine to include EDTA in 2006. With the approval and relaunch of liquid Leukine in a non-EDTA formulation, Bayer is closing a special access program that reserved priority access to lyophilized Leukine 250 mcg vials, which do not contain EDTA, for patients with the greatest medical need. Sufficient supply of the new, non-EDTA liquid and lyophilized formulations of Leukine is now available to meet cancer care market demand.
"At Bayer, providing effective and safe medicines for patients is our highest priority," said Paul MacCarthy, MD, FRCPI, vice president and head of U.S. Medical Affairs for Bayer HealthCare Pharmaceuticals. "Bayer is pleased to bring back to U.S. oncologists and hematologists an EDTA-free formulation of liquid Leukine for the care of their patients. Liquid Leukine without EDTA has been used in the treatment of more than 200,000 cancer patients." New data will be reported at the upcoming American Society for Clinical Oncology (ASCO) conference regarding the clinical impact of Leukine in cancer care.
The EDTA-free formulation of liquid Leukine is presented in Bayer HealthCare Pharmaceuticals' branded packaging. The product was previously marketed under the Berlex Laboratories brand. Berlex was acquired by Bayer.
Bayer has posted a Dear Health Care Provider letter, along with its enclosures, on its websites today at www.pharma.bayer.com, www.bayeroncology.com and www.Leukine.com and will be mailing it to U.S. oncologists and hematologists who prescribe and use Leukine for their patients.

Leukine has been used to treat nearly 350,000 cancer patients in the United States since 1991. Among its indications, Leukine is the only myeloid growth factor approved to reduce the incidence of severe and life-threatening infections and infections resulting in death following induction chemotherapy in older adult patients (> 55 years of age) with AML and to prolong survival of patients have undergone allogeneic or autologous bone marrow transplantation (BMT) and are experiencing graft failure or engraftment delay, as compared to historical experience.
Important Safety Considerations
Leukine is contraindicated in patients with excessive leukemic blasts in bone marrow or peripheral blood (greater than or equal to 10%), in patients with known hypersensitivity to GM-CSF, yeast-derived products or any component of Leukine, and for concomitant use with chemotherapy and radiotherapy.
Serious allergic or anaphylactic reactions have been reported with Leukine. If any serious or anaphylactic reactions occur, Leukine therapy should immediately be discontinued and appropriate therapy initiated.
Liquid solutions containing benzyl alcohol (including liquid Leukine) or lyophilized Leukine reconstituted with Bacteriostatic Water for Injection, USA (0.9% benzyl alcohol) should not be administered to neonates.
Leukine should be used with caution and monitored in patients with preexisting fluid retention, pulmonary infiltrates or CHF; respiratory symptoms or disease; cardiac symptoms or disease; and renal or hepatic dysfunction.
Edema, capillary leak syndrome, pleural and or/pericardial effusion, supraventricular tachycardia, sequestration of granulocytes in the pulmonary circulation and dyspnea have been reported in patients after Leukine administration. Leukine has induced the elevation of serum creatinine or bilirubin and hepatic enzymes in some patients. Monitoring of renal and hepatic function in patients with preexisting renal or hepatic dysfunction is recommended at least every other week during Leukine administration.
Nearly all patients reported leukopenia, thrombocytopenia, and anemia. Adverse events occurring in >10% of AML patients receiving Leukine in controlled clinical trials and reported in a higher frequency than placebo were: fever, skin reactions, metabolic disturbances, nausea, vomiting, weight-loss, edema, and anorexia.
If ANC >20,000 cells/mm3 or if platelet counts >500,000 mm3, Leukine administration should be interrupted or the dose reduced by half. Twice weekly monitoring of CBC with differential should be performed.
Leukine therapy should be discontinued if disease progression is detected during treatment.
