Nplate® is a thrombopoietin receptor agonist indicated for the treatment of thrombocytopenia in adult patients with immune thrombocytopenia (ITP) who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy. Nplate® is indicated for the treatment of thrombocytopenia in pediatric patients 1 year of age and older with ITP for at least 6 months who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy.
Nplate® is not indicated for the treatment of thrombocytopenia due to myelodysplastic syndrome (MDS) or any cause of thrombocytopenia other than ITP. Nplate® should be used only in patients with ITP whose degree of thrombocytopenia
and clinical condition increase the risk for bleeding. Nplate® should not be used in an attempt to normalize platelet counts.
In 2019 the American Society of Hematology (ASH) and the International Consensus Report (ICR) released updates to their guidelines for ITP treatment. These updates are based on a critical review of relevant articles published over the last 10 years.7,8
Recent evidence suggests that ITP is often managed with prolonged steroid use, exposing patients to side effects that may have long-term implications.7

*Rituximab is not FDA-approved for use in ITP.5
See how Nplate® may be right for your patientsTreatment-free remission was a secondary endpoint defined as maintaining every platelet count at ≥ 50 x 109/L for at least 6 months in the absence of any ITP treatment, and occurred in 32% (n = 24/75) of patients.1,2
The primary endpoint of the study (N = 75) was the cumulative number of months in which patients achieved a platelet response.2
*Nplate® was initiated following a platelet count ≤ 30 x 109/L at any time during the 4-week screening period. Nplate® was initiated within 6 months of ITP diagnosis.1,2
*First-line treatments could have also included immunoglobulins, anti-D immunoglobulin, or vinca alkaloids.2
†Adjustments were made following the recommended dosage regimen (Section 2.1 of the Nplate® Prescribing Information).
TPO-RA, thrombopoietin receptor agonist.
*32% of patients achieved treatment‑free remission.1,2
†This regimen includes reducing, withholding, and discontinuing Nplate® if/when platelet counts exceed certain levels. Of the 24 patients who achieved treatment‑free remission, 20 (83%) discontinued Nplate® based on this regimen during the 52-week treatment period; 4 patients (17%) tapered Nplate® at the end of the 52-week treatment period using a different dosage adjustment approach per the study protocol.1‑3

Nplate® administration may increase the risk for development or progression of reticulin fiber formation within the bone marrow. This formation may improve upon discontinuation of Nplate®. In a clinical trial, one patient with ITP and hemolytic anemia developed marrow fibrosis with collagen during Nplate® therapy.
