Brief Summary
The goal of this observational study is to compare the fluctuation patterns of biomarkers (Spirometry, FeNO, IOS) of responders and non-responders in asthma patients who will start treatment with a biologic. The main question it aims to answer is: Can fluctuation patterns of parameters for spirometry, FeNO and IOS before and after starting treatment with biologics in patients with severe asthma be used to predict a successful intervention. Participants will measure Spirometry, FeNO and IOS twice a day at home for 2 or 3 months starting one month before starting treatment with a biological.

Outcome Measures
Primary Outcomes (8)
Fluctuation pattern of spirometry
Subjects will perform spirometry measurements 2x a day. This data will be used to create a fluctuation pattern of the FEV1(L) and FVC (L). The change in fluctuation pattern before and after start of treatment will be compared between responders and non-responders to treatment with a biological. The fluctuation pattern cannot be described as one parameter, but is a combination of several properties (phase-space plot, entropy). This study has an explorative nature that will aim to assess how such a fluctuation pattern can be described.
2-3 months
Fluctuation pattern of FeNO
Subjects will perform FeNO measurements 2x a day. This data will be used to create a fluctuation pattern of FeNO (ppb). The change in fluctuation pattern before and after start of treatment will be compared between responders and non-responders to treatment with a biological. The fluctuation pattern cannot be described as one parameter, but is a combination of several properties (phase-space plot, entropy). This study has an explorative nature that will aim to assess how such a fluctuation pattern can be described.
2-3 months
Fluctuation pattern of IOS
Subjects will perform impulse oscillometry (IOS) measurements 2x a day. This data will be used to create a fluctuation pattern of the IOS parameters (R5, R20, X5, Fs, AX etc). The change in fluctuation pattern before and after start of treatment will be compared between responders and non-responders to treatment with a biological. The fluctuation pattern cannot be described as one parameter, but is a combination of several properties and parameters (phase-space plot, entropy). This study has an explorative nature that will aim to assess how such a fluctuation pattern can be described.
2-3 months
Treatment success with biological
Treatment success is defined if two or more of the following are true: * A decrease of ACQ score of 0,5 points or an ACQ≤1,5 after 4-6 months compared to visit 2 (start of treatment with biological) and/or * An increase of SAQ score of 0,5 points after 4-6 months compared to visit 2 (start of treatment with biological) and/or * Minimal 30% reduction of dose of maintenance treatment with OCS after 4-6 months compared to visit 2 (start of treatment with biological) * and/or Decrease in exacerbation rate in the 4-6 months after visit 2 compared to the same period (4-6 months) before visit 2
at 4-6 months after start treatment with biological
trend of Asthma Control Questionnaire
average of 7 questions regarding asthma control (scorerange 0-6), higher score means worse asthma control
1x a week for 2-3 months + at 4-6 months after start treatment with biological
trend of Asthma Quality of Life Questionnaire
average of 32 questions regarding impact of asthma on quality of life (scorerange 1-7), higher score means better quality of life
1x a week for 2-3 months + at 4-6 months after start treatment with biological
trend of Severe Asthma Questionnaire
SAQ-score: average of 16 questions regarding severe asthma (scorerange 1-7), higher score means better quality of life. SAQ-global: score representing overall satisfaction (scorerange 0-100)
1x a week for 2-3 months + at 4-6 months after start treatment with biological
trend of PESAM questionnaire
Patient Experience and SAtisfaction with Medication (PESAM) represents patients satisfaction with the treatment with the biological
at 1+ 2 (if applicable) + 4-6 months after start treatment with biological

You may qualify if:
- In order to be eligible to participate in this study, a subject must meet all of the following criteria:
- Severe asthma based on the definition by the 2022 GINA guidelines.
- Will start treatment with a biological
