5 Unique FAQs
1. How does resistance to ibrutinib develop, and what are the implications?
Resistance often arises through mutations such as BTK C481S, which prevents covalent binding of ibrutinib. This reduces drug efficacy, prompting the development of non-covalent inhibitors and combination therapies to overcome resistance.
2. Which patient populations are most likely to benefit from ibrutinib?
Patients with relapsed/refractory CLL or MCL, especially elderly or comorbid individuals who are less tolerant of chemotherapy, benefit most due to drug’s oral administration and favorable safety profile.
3. What are the main safety concerns associated with ibrutinib?
Atrial fibrillation, bleeding risks, hypertension, infections, and cytopenias are notable adverse events. Real-world data suggest tolerability improves with dose adjustments and careful patient monitoring.
4. How will biosimilars impact ibrutinib's market share?
Biosimilar development, particularly post-patent expiry (~2027), may lower prices and increase accessibility, but the impact depends on regulatory approvals, patent litigations, and market acceptance.
5. What is the outlook for ibrutinib in combination therapies?
Combining ibrutinib with other agents like venetoclax or immunotherapies enhances depth of response and may prolong remission, thereby expanding the market and improving patient outcomes.
