DrugPatentWatch employs three methods to identify biologic patents:

1. Brand-side disclosures in response to biosimilar applications

These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

2. DrugPatentWatch analysis and company disclosures

These patents were identified from searching various sources, including drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

3. Patents from broad patent text search

For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

Market Dynamics and Financial Trajectory for the Biologic Drug NPLATE

Last updated: September 19, 2025

Introduction

NPLATE (romiplostim) is a biologic therapeutic approved by the U.S. Food and Drug Administration (FDA) for the treatment of immune thrombocytopenic purpura (ITP). As a thrombopoietin receptor agonist, NPLATE stimulates platelet production, effectively managing a chronic autoimmune disorder characterized by low platelet counts. The biological complexities, competitive landscape, evolving clinical guidelines, and regulatory trends considerably influence its market dynamics and financial trajectory. This analysis explores the key drivers shaping NPLATE’s market presence and provides strategic insights for stakeholders.

Market Overview and Clinical Context

Indications and Clinical Demand

NPLATE primarily treats ITP in adults and children, especially cases refractory to first-line therapies such as corticosteroids and splenectomy. Its pivotal clinical advantage lies in the ability to increase and sustain platelet counts, reducing bleeding risk. The global prevalence of ITP is estimated at approximately 3.3 per 100,000 adults annually, with higher incidences observed in females and older populations [1]. Growing prevalence, coupled with increased awareness and better diagnostic protocols, sustains a steady demand trajectory.

Competitive Positioning

NPLATE faces competition chiefly from other thrombopoietin receptor agonists like eltrombopag (Promacta) and avatrombopag (Doptelet).
