BARDA Awards $37.6 million Contract to Sanofi to Supply Leukine® (sargramostim) for Potential Public Health Emergency

CAMBRIDGE, Mass.--()--Sanofi Genzyme, the specialty care global business unit of Sanofi, announced today that the Biomedical Advanced Research and Development Authority (BARDA), within the Office of the Assistant Secretary for Preparedness and Response in the U.S. Department of Health and Human Services, has awarded Sanofi a $37.6 million contract to supply and manage inventory for Leukine®.

Sanofi Genzyme is developing Leukine for the treatment of acute radiation syndrome. Acute radiation syndrome is a serious illness that occurs in people exposed to high doses of radiation. The condition involves injuries to the body’s organs, including the bone marrow, gastrointestinal tract, and lungs, and can cause neutropenia, an abnormally low level of white blood cells that fight infection called neutrophils.

“According to the Centers for Disease Control and Prevention, the cause of death in most cases of acute radiation syndrome is the destruction of the person's bone marrow1,” said Richard Peters, Sanofi Genzyme’s Global Head of Rare Diseases. “We are pleased to be able to partner with BARDA to support public health.”

In 2013, Sanofi was awarded a $36.5 million contract for late stage development and procurement of Leukine. Since then Sanofi Genzyme has conducted studies regarding the potential use of Leukine in patients acutely exposed to myelosuppressive doses of radiation (Hematopoietic Syndrome of Acute Radiation Syndrome). Sanofi Genzyme expects to submit a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration next year.

BARDA provides an integrated, systematic approach to the development and purchase of the necessary vaccines, drugs, therapies, and diagnostic tools for public-health medical emergencies.

About Leukine

Leukine® (sargramostim) is indicated for the following uses: (i) following induction chemotherapy in older adult patients with acute myelogenous leukemia (AML) to shorten time to neutrophil recovery; (ii) for mobilization and following transplantation of autologous peripheral blood progenitor cells; (iii) for myeloid reconstitution after autologous or allogeneic bone marrow transplantation (BMT); (iv) for use in bone marrow transplantation failure or engraftment delay.

Important Safety Information for Leukine® (sargramostim)

  • Leukine is contraindicated in patients with excessive leukemic myeloid blasts in bone marrow or peripheral blood (≥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 allergic or anaphylactic reactions occur, Leukine therapy should be immediately discontinued and appropriate therapy initiated.
  • Liquid solutions containing benzyl alcohol (including liquid Leukine) or lyophilized Leukine reconstituted with Bacteriostatic Water for Injection, USP (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 congestive heart failure, respiratory symptoms or disease; cardiac symptoms or disease; and renal or hepatic dysfunction.
  • Edema, capillary leak syndrome, pleural and/or pericardial effusion, sequestration of granulocytes in the pulmonary circulation, and dyspnea have been reported in patients after Leukine administration. Occasional transient supraventricular arrhythmia has been reported during 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.
  • Adverse events occurring in >10% of patients receiving Leukine in controlled clinical trials and reported in a higher frequency than placebo were: in AML patients – (fever, skin reactions, metabolic disturbances, nausea, vomiting, weight-loss, edema, anorexia); in Autologous BMT patients – (asthenia, malaise, diarrhea, rash, peripheral edema, urinary tract disorder); and in Allogeneic BMT patients – (abdominal pain, chills, chest pain, diarrhea, nausea, vomiting, hematemesis, dysphagia, GI hemorrhage, pruritus, bone pain, arthralgia, eye hemorrhage, hypertension, tachycardia, bilirubinemia, hyperglycemia, increased creatinine, hypomagnesemia, edema, pharyngitis, epistaxis, dyspnea, insomnia, anxiety, high BUN, and high cholesterol).
  • 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.
  • Drugs that can increase WBCs, such as lithium and corticosteroids, should be used with caution while receiving Leukine. Interactions between Leukine and other drugs have not been fully evaluated.
