Frequently Asked Questions (FAQs)
1. What are the primary clinical indications for Lomustine today?
Lomustine is primarily indicated for recurrent high-grade gliomas, Hodgkin’s lymphoma, and occasionally primary CNS lymphoma. Its use in other indications remains experimental or off-label.
2. Is Lomustine likely to be replaced by newer agents in the near future?
While newer agents like Temozolomide are preferred for certain indications due to better tolerability, Lomustine’s role persists in refractory settings and combination protocols. The ongoing clinical trials could bolster its position if synergistic benefits are confirmed.
3. What are the major toxicity concerns associated with Lomustine?
Myelosuppression (neutropenia, thrombocytopenia), hepatotoxicity, and pulmonary fibrosis are significant adverse effects that require monitoring. Dose adjustments and supportive care are essential components of management.
4. How will biosimilars impact the Lomustine market?
Introduction of biosimilars can reduce prices, increase access, and stimulate competitive dynamics. Given Lomustine’s patent expiration, biosimilar development is likely, especially in emerging markets.
5. Are there emerging combination therapies involving Lomustine showing promise?
Yes, clinical trials combining Lomustine with immune checkpoint inhibitors, targeted therapies, and radiotherapy are underway, showing potential for improved efficacy in gliomas and CNS lymphomas.
