Did the Drug Fail, or Did the Measurement Fail?
Exhaled breath condensate (EBC) is a non-invasive tool that provides airway-level biological context in early-phase respiratory drug development, helping to distinguish whether ambiguous trial results are due to drug failure or inadequate measurement. EBC is most valuable when the pharmacodynamic question is lung-compartment specific and cannot be answered by blood or FeNO, but its biomarkers are exploratory and require a pre-specified analysis plan for meaningful interpretation. While EBC does not provide validated endpoints, its inclusion can inform critical development decisions by adding mechanistic insight that systemic measures alone cannot offer.
How We Manufacture the RTube™
Because even trace contaminants can skew biomarker data, Respiratory Research, Inc. employs a proprietary cleaning process that removes both chemical residues and organic matter. Manufactured in an ISO 8 cleanroom, each RTube™ is sealed to guarantee pristine breath analysis—ensuring accurate breath biomarkers with every use.
Effectiveness of Exhaled Breath Condensate Collection Using RTube® and Cooling Sleeve Chilled in Household Freezer
Chilled in a household freezer, the RTube® reliably collects Exhaled Breath Condensate for breath analysis and breath biomarkers. This study shows yields remain near-constant across a wide temperature range, reinforcing RTube’s consistent performance in real-world clinical conditions.
Journal Article Summary – Measuring RNA in Breath Condensate
The RTube has successfully been used to isolate RNA, microRNA, and DNA from Exhaled Breath Condensate (EBC). While the collection process of EBC is similar for each target, the isolation steps differ. This Journal Article Summary, based on Dr. Guillermo Barreto’s EMBO Medicine study, highlights a non-invasive approach to nucleic acid isolation for early-stage lung cancer detection.
