ON-TREATMENT ASTHMA REMISSION:
MOVING BEYOND CONTROL

Proposed Framework for Remission1-7

Remission: A state or period with low to no disease activity
that can be spontaneous or as a result of therapy6

Several Countries Have Recommended Clinical Remission Definitions1-5

* The US workgroup determined that symptom and lung function criteria must be met on all occasions measured in the previous 12-month period with a minimum of two measurements during the year.

The definition of on-treatment remission in asthma has not yet been established
and further consensus among experts, guidelines, and societies is warranted.

EVOLUTION OF ON-TREATMENT
REMISSION IN ASTHMA

How Can Therapeutic Intervention Get Us to On-Treatment
Clinical Remission?6-10

Natural Disease Course

Therapeutic Intervention

*Disease remission is broadly defined as a state or period with low to no disease activity and can be spontaneous or a result of therapy 1
†Disease modification is an evolving topic in asthma and further study is required to demonstrate whether current interventions have the potential to modify
   disease.

Over 70-Years of On-Treatment Clinical Remission in Asthma

Remission may be achieved on or off treatment. Different definitions of remission have been
proposed and implemented in various studies. Given this evolving framework for remission, further
studies may provide a pathway to inform our understanding of disease modification in severe asthma.

ICS, inhaled corticosteroids; LABA, long-acting beta agonist; SABA, short-acting beta agonist; SCS, systemic corticosteroids.

REDUCING EXACERBATIONS
IS A FUNDAMENTAL CRITERION OF
ASTHMA REMISSION1-7

Asthma Control15,16*

Zero exacerbations requiring
hospitalization in previous 12 months

On-Treatment Clinical Remission1-7

For ≥12 Months

Zero exacerbations

*Adapted from GINA and ERS/ATS. †Severe exacerbation was defined as worsening asthma requiring at least 3 days of treatment with systemic corticosteroids, or a hospitalization due to asthma.
