FAQs

1. How does VARUBI’s mechanism of action differ from other NK1 antagonists?
VARUBI (rolapitant) has a longer half-life (~170 hours) compared to aprepitant (~9-13 hours), allowing it to maintain NK1 blockade over a delayed period, potentially reducing breakthrough nausea and improving compliance.

2. What are the main factors limiting VARUBI’s market share?
Intense competition, especially from aprepitant-based agents, price pressures, and limited awareness outside specialized oncology centers restrict broader adoption.

3. Are there any upcoming regulatory approvals for VARUBI?
Currently, no new indications are pending approval; however, ongoing clinical trials aim to expand its use into pediatric populations and high-dose chemotherapy regimens.

4. How might biosimilars or generics impact VARUBI’s market?
Potential patent expirations post-2024 could invite biosimilar or generic competition, likely leading to price deflation and market share erosion unless differentiated by new indications.

5. What strategic moves can GSK leverage to sustain VARUBI’s growth?
GSK can explore combination therapies, broaden international access, accelerate pediatric and alternative indications, and invest in real-world evidence to reinforce efficacy claims.
