FAQs
1. How does TERLIVAZ (Zarxio) differ from Neupogen?
TERLIVAZ is a biosimilar version of Neupogen, meaning it has demonstrated biosimilarity in terms of safety, efficacy, and quality but is not identical due to manufacturing processes. It offers cost advantages, with similar clinical performance.
2. What is the significance of FDA’s interchangeability designation for biosimilars like TERLIVAZ?
Interchangeability permits pharmacy-level substitution without prescriber intervention, significantly accelerating market penetration and usage, thereby boosting sales.
3. How do price discounts impact the profitability of biosimilars like TERLIVAZ?
Lower list prices attract payer and provider preference, increasing volume. However, biosimilars often operate at thin margins with high market share targets needed to sustain profitability.
4. What is the future outlook for biosimilars in the oncology space?
The emerging regulatory environment and increasing acceptance by payers and clinicians predict ongoing growth for biosimilars in oncology, including G-CSFs like TERLIVAZ.
5. Are there ongoing patent litigations threatening TERLIVAZ’s market share?
While patent disputes are common in biologics, Sandoz has managed to defend TERLIVAZ's market access so far. Future litigations could influence timelines but are expected to be managed or settled.
