How has the LCQ been used in real-world evidence (RWE) studies for chronic cough in the US?
Answer: To document QoL burden and treatment gaps in large patient registries
Real-world evidence studies in the US have used the LCQ in patient registries to document the quality of life burden of chronic cough and identify unmet treatment needs.
What normative LCQ data exists for healthy (non-coughing) adults?
Answer: Limited normative data exists, making interpretation relative to clinical change rather than population norms
Normative LCQ data for healthy adults is limited; clinical interpretation therefore relies on within-patient change scores and established MCIDs rather than comparison to population norms.
Which research finding demonstrated the LCQ's ability to detect improvements after speech language pathology cough suppression therapy?
Answer: Significantly improved LCQ scores post-SLP therapy in RCTs
Randomized controlled trials of speech language pathology cough suppression therapy have demonstrated significant LCQ score improvements, confirming the tool's responsiveness to behavioral interventions.
In terms of REGULATORY acceptance, how has the LCQ been used in US FDA submissions?
Answer: As a patient-reported outcome supporting drug approvals for chronic cough indications
The LCQ has been included as a patient-reported outcome in FDA submissions for chronic cough drugs, contributing to regulatory evidence packages alongside primary efficacy endpoints.
What gap in LCQ research has been identified in recent literature?
Answer: Limited long-term data on LCQ score stability in untreated chronic cough patients
Recent literature identifies a gap in long-term natural history data on LCQ scores in untreated chronic cough patients, limiting understanding of how scores change without intervention.
How has the LCQ been used to demonstrate unmet medical need for chronic cough treatments to US payers?
Answer: By documenting persistently low LCQ scores in patients who have failed standard therapies
Persistently low LCQ scores in patients who have tried multiple treatments without improvement demonstrate unmet medical need, supporting access and reimbursement arguments for new therapies with US payers.
