Unlocking Asthma Remission: Key Insights From an Expert Roundtable Discussion

ABSTRACT Treatment targets in severe asthma have evolved towards a remission‐focused paradigm guided by precision medicine. This novel concept requires a shift from evaluating the efficacy of therapies based on a single outcome at a single time point to an outcome that captures the complexity of asthma remission involving several domains assessed over a sustained period. Since the concept is still emerging, multiple definitions have been proposed, ranging from symptom control and exacerbation‐free to resolution of underlying pathobiology, with varying rigour in each parameter. Understanding the strengths and weaknesses of the current construct is needed to progress further. We conducted a roundtable discussion with 27 asthma experts to address this issue, and discussions were narratively synthesised and summarised. The participants observed that between one in three and one in five people treated with targeted biological therapies or macrolides experience low disease activity over a sustained period. They unanimously agreed that labelling the attained clinical state as clinical remission is useful as a clinical (e.g., facilitating a treat‐to‐target approach), policy (e.g., widening eligibility criteria for biologics), and scientific (e.g., a path to understanding cure) tool. Current remission rates vary significantly due to definition variability. When assessing remission, it is essential to consider confounding factors (e.g., steroid use for adrenal insufficiency). More research is required to reach an acceptable definition, and including the patient's voice in such research is essential. In conclusion, the concept of treatment‐induced clinical remission is possible and valuable in asthma. However, further refinement of the definition is required.
