Allergic Reactions Including Anaphylaxis
Neumega has caused allergic or hypersensitivity reactions, including anaphylaxis. Administration of Neumega should be permanently discontinued in any patient who develops an allergic or hypersensitivity reaction (see
WARNINGS, CONTRAINDICATIONS, ADVERSE REACTIONS
ADVERSE REACTIONS, Immunogenicity).
Interleukin eleven (IL-11) is a thrombopoietic growth factor that directly stimulates the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells and induces megakaryocyte maturation resulting in increased platelet production. IL-11 is a member of a family of human growth factors which includes human growth hormone, granulocyte colony-stimulating factor (G-CSF), and other growth factors.
Neumega is indicated for the prevention of severe thrombocytopenia and the reduction of the need for platelet transfusions following myelosuppressive chemotherapy in adult patients with nonmyeloid malignancies who are at high risk of severe thrombocytopenia. Efficacy was demonstrated in patients who had experienced severe thrombocytopenia following the previous chemotherapy cycle. Neumega is not indicated following myeloablative chemotherapy (see WARNINGS, Increased Toxicity Following Myeloablative Therapy). The safety and effectiveness of Neumega have not been established in pediatric patients.
Published Studies Related to Neumega (Oprelvekin)
Oprelvekin-associated bilateral optic disk edema. [2005.02]
PURPOSE: To report a case of bilateral optic disk edema in a patient taking oprelvekin for radioimmunotherapy-induced thrombocytopenia. DESIGN: Observational case report... CONCLUSIONS: Oprelvekin therapy may be associated with bilateral optic disk edema. This has been shown to be reversible in a primate model.
A multiple-dose, safety, tolerability, pharmacokinetics and pharmacodynamic study of oral recombinant human interleukin-11 (oprelvekin). [2004.10]
A study in healthy men and women was performed to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of orally administered recombinant human interleukin-11 (oprelvekin) (OAO). Four cohorts of 10 subjects each received 3, 5, 10 or 30 mg (8:2/OAO:placebo ratio), first as a single dose with a 7-day washout period, then 7 consecutive daily doses...
Periostitis secondary to interleukin-11 (Oprelvekin, Neumega). Treatment for thrombocytopenia in pediatric patients. [2003.07]
Interleukin-11 (Oprelvekin, Neumega) is a newly introduced thrombopoietic growth factor that stimulates production, differentiation, and maturation of megakaryocytes and platelets...
Pharmacoeconomic analysis of oprelvekin (recombinant human interleukin-11) for secondary prophylaxis of thrombocytopenia in solid tumor patients receiving chemotherapy. [2003.06.15]
BACKGROUND: Previous research has shown oprelvekin (recombinant human interleukin-11 [rhIL-11]) to be effective in reducing the requirements for platelet transfusions after myelosuppressive chemotherapy in patients who have previously experienced thrombocytopenia. The economic consequences of the routine use of this platelet growth factor and the usual standard of platelet transfusions for prophylaxis of severe chemotherapy-induced thrombocytopenia have not been compared... CONCLUSIONS: From the payer's perspective, rhIL-11 cannot be considered a cost-saving clinical strategy compared with routine platelet transfusions for patients with severe chemotherapy-induced thrombocytopenia.

Oprelvekin. Genetics Institute. [2001.10]
Genetics Institute has developed and launched oprelvekin (rhIL-11; Neumega), a recombinant form of human IL-11. In November 1997, the FDA cleared oprelvekin for the prevention of severe thrombocytopenia and the reduction of the need for platelet transfusions following myelosuppressive chemotherapy in susceptible patients with non-myeloid malignancies 12703021...
Clinical Trials Related to Neumega (Oprelvekin)
Study Evaluating The Effects Of Oprelvekin On Cardiac Repolarization In Subjects With Chemotherapy Induced Thrombocytopenia [Recruiting]
This is an open-label study in which oprelvekin will be administered for the prevention of
severe low blood platelet cell counts (cells in your blood that keep bleeding and clotting
stable) in adults with cancer who are taking chemotherapy (anti-cancer drug) that has a side
effect of blocking your bone marrow from making platelet cells. The purpose of this study is
to learn more about the effects of the recommended dose of oprelvekin on the heart's
Phase II Study of IL-11 (Neumega) in Von Willebrand Disease [Completed]
This study is testing the use of rhIL-11 (recombinant interleukin 11, Neumega) in
individuals with Von Willebrand disease. The purpose is to evaluate:
1. if rhIL-11 corrects VWF (Von Willebrand Factor) levels to normal
2. if rhIL-11 and DDAVP together will boost VWF levels even higher
3. the onset, peak, and duration of rhIL-11 effect
4. if rhIL-11 is safe in individuals with Von Willebrand Disease
Interleukin 11, Thrombocytopenia, Imatinib in Chronic Myelogenous Leukemia (CML) Patients [Completed]
The goal of this clinical research study is to find out if IL-11 (NeumegaTM) may increase
the platelet count in patients with Chronic myeloid leukemia (CML) who develop low platelet
counts while receiving therapy with imatinib mesylate (Gleevec, STI571), or other tyrosine
kinase inhibitors such as AMN107, dasatinib, or SK1606.
1. To determine efficacy of low-dose interleukin-11, (IL-11, oprelvekin, NeumegaTM) in
improving the thrombocytopenia associate with imatinib or other tyrosine kinase inhibitor
therapy in patients with CML.
1. To determine the safety of low-dose IL-11 in patients with CML and thrombocytopenia
associated with imatinib or other tyrosine kinase inhibitors
Efficacy and Safety of IL-11 in DDAVP Unresponsive [Completed]
The purpose of this study is to determine the biologic efficacy and safety of rhIL-11 when
given subcutaneously in adults with moderate or mild hemophilia A or Von Willebrand disease
unresponsive to DDAVP. Biologic efficacy will be measured by the number and percent increase
of VWD coagulation tests (FVIII: C, VWF: Ag, VWF: RCo, closure time, APTT, and VWF multimers)
to the normal range, or at least to 1. 5-3 time baseline, following dosing of rhIL-11 when
given daily for 4 days, and boosted by DDAVP infusion on day 4, in those in whom DDAVP is
not contraindicated. Safety will be measured by the frequency of adverse events, including
fever, headache, fatigue, myalgias, arthralgias, fluid retention, or edema.
Recombinant Human Interleukin-11 Combination Low-dose Rituximab in Immune Thrombocytopenia [Recruiting]
The purpose of this study is to determine whether Recombinant Human Interleukin-11 (rhIL-11)
Combination Low-dose Rituximab prednisone are effective and safe in the management of
Steroid-Resistant/Relapsed Immune Thrombocytopenia (ITP).
