FAQs
Q1: What are the mechanisms of action of Elexacaftor, Ivacaftor, and Tezacaftor?
A1: Elexacaftor and Tezacaftor act as CFTR correctors, enhancing the trafficking of the CFTR protein to the cell surface, while Ivacaftor functions as a potentiator, increasing the activity of CFTR channels on cell membranes.
Q2: How does the combination therapy compare to Ivacaftor monotherapy in terms of efficacy?
A2: The triple combination (Elexacaftor/Tezacaftor/Ivacaftor) demonstrates approximately a 13% improvement in ppFEV1, compared to 10–12% with Ivacaftor monotherapy, along with broader mutation coverage.
Q3: What are the leading challenges facing the commercialization of CF modulators?
A3: Challenges include high production costs, reimbursement policies, access disparities, and potential long-term safety concerns.
Q4: Are there ongoing trials exploring the use of these drugs in pediatric populations?
A4: Yes, multiple trials are evaluating safety and efficacy in children aged 6–11 years, potentially broadening treatment access.
