INDICATIONS

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.

Rapid Efficacy That Lasts2,3

Nplate® is the only approved immune thrombocytopenia (ITP) therapy with treatment-free remission in the label2,3

93% of patients achieved any platelet response
93% of patients achieved any platelet response*
(n = 70/75)2
Approximately one-third of ITP patients achieved treatment-free remission
~ 1/3 of patients achieved treatment-free remission
(n = 24/75)2,3
Responses seen as early as seven days with median of 2.1 weeks
Responses seen as early

  • ASH ITP guidelines suggest Nplate® as a second-line therapy over non–TPO-RAs like rituximab and limiting duration of steroids to ≤ 6 weeks6,‡

Lasting stability: 61% of patients achieved a response for ≥ 11 months (n = 46/75)3

*Platelet response was defined as a platelet count ≥ 50 x 109/L during 12-month treatment period.2

†95% CI: 1.1, 3.0; 5.56%, 47.22%, and 61.11% of patients responded by weeks 1, 2, and 3, respectively.2,5

‡Rituximab is not FDA-approved for use in ITP.7

  • Study Design
    Nplate® was studied in a 52-week, open-label, single-arm, phase 2 trial of 75 adults with ITP for ≤ 6 months who had an insufficient response (platelet count ≤ 30 x 109/L) to first-line ITP treatment, including corticosteroids. Treatment-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.2,3,5,8

Established Safety Profile Without Food Restrictions

Nplate® is the once-weekly, in-office, subcutaneous injection that offers:

5 years
No new safety signals observed up to 5 years of continuous treatment9,*
No daily pill reminders
No need to remember to take a pill every day2,10-12
No liver monitoring required
No liver monitoring, and no known drug interactions or dietary restrictions2,4

*Long-term safety data: Based on an open-label, single-arm, extension study of 291 adults with chronic ITP who had at least one dose of Nplate®. Subjects could enter any time during the 277-week period. Mean treatment duration was 110 weeks. Study results: AEs did not increase in frequency or type with longer Nplate® drug exposure. Primary assessment/incidence: Serious treatment-related AEs, 8% (24/291); thrombotic events, 6.5% (19/291); bone marrow reticulin increase, 1.4% (4/291); neutralizing antibody formation, < 1% (2/291); and deaths, 5% (16/291).2,9

Important Safety Information

Risk of Progression of Myelodysplastic Syndromes to Acute Myelogenous Leukemia

  • In Nplate® (romiplostim) clinical trials of patients with myelodysplastic syndromes (MDS) and severe thrombocytopenia, progression from MDS to acute myelogenous leukemia (AML) has been observed.
  • Nplate® is not indicated for the treatment of thrombocytopenia due to MDS or any cause of thrombocytopenia other than ITP.

Thrombotic/Thromboembolic Complications

  • Thrombotic/thromboembolic complications may result from increases in platelet counts with Nplate® use. Portal vein thrombosis has been reported in patients with chronic liver disease receiving Nplate®.
  • To minimize the risk for thrombotic/thromboembolic complications, do not use Nplate® in an attempt to normalize platelet counts. Follow the dose adjustment guidelines to achieve and maintain a platelet count of ≥ 50 x 109/L.

Loss of Response to Nplate®

  • Hyporesponsiveness or failure to maintain a platelet response with Nplate® should prompt a search for causative factors, including neutralizing antibodies to Nplate®.
  • To detect antibody formation, submit blood samples to Amgen (1‑800‑772‑64361‑800‑772‑6436). Amgen will assay these samples for antibodies to Nplate® and thrombopoietin (TPO).
  • Discontinue Nplate® if the platelet count does not increase to a level sufficient to avoid clinically important bleeding after 4 weeks at the highest weekly dose of 10 mcg/kg.
Adverse Reactions
Adult ITP
  • In the placebo-controlled trials of adult ITP patients, headache was the most commonly reported adverse drug reaction, occurring in 35% of patients receiving Nplate® and 32% of patients receiving placebo. Adverse drug reactions in adults with a ≥ 5% higher patient incidence in Nplate® versus placebo were Arthralgia (26%, 20%), Dizziness (17%, 0%), Insomnia (16%, 7%), Myalgia (14%, 2%), Pain in Extremity (13%, 5%), Abdominal Pain (11%, 0%), Shoulder Pain (8%, 0%), Dyspepsia (7%, 0%), and Paresthesia (6%, 0%).
  • The safety profile of Nplate® was similar across patients, regardless of ITP duration. The following adverse reactions (at least 5% incidence and at least 5% more frequent with Nplate® compared with placebo or standard of care) occurred in Nplate® patients with ITP duration up to 12 months: bronchitis, sinusitis, vomiting, arthralgia, myalgia, headache, dizziness, diarrhea, upper respiratory tract infection, cough, nausea and oropharyngeal pain. The adverse reaction of thrombocytosis occurred with an incidence of 2% in adults with ITP duration up to 12 months.
Pediatric ITP
  • The most common adverse reactions experienced by ≥ 5% of patients receiving Nplate® with ≥ 5% higher incidence in the Nplate® arm across the two placebo-controlled trials were contusion (41%), upper respiratory tract infection (31%), oropharyngeal pain (25%), pyrexia (24%), diarrhea (20%), rash (15%), and upper abdominal pain (14%).
  • In pediatric patients of age ≥ 1 year receiving Nplate® for ITP, adverse reactions with an incidence of ≥ 25% in the two randomized trials were: contusion (41%), upper respiratory tract infection (31%), and oropharyngeal pain (25%).
  • In a long-term, single arm, open label pediatric safety study, headache occurred in 78/203 patients (38%); the incidence rates of other adverse reactions were similar to those reported in the placebo-controlled studies.

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.
