A Study to Find Out Whether BI 1015550 Improves Lung Function in People With Idiopathic Pulmonary Fibrosis (IPF)

This study is open to adults with a lung disease called Idiopathic Pulmonary Fibrosis (IPF). People can join the study if they are 40 years or older. If they already take nintedanib or pirfenidone for their IPF, they can continue treatment throughout the study. The purpose of this study is to find out whether a medicine called BI 1015550 helps people with IPF.

Participants are put into 3 groups randomly, which means by chance. Participants in 2 groups take different doses of BI 1015550 as tablets twice a day. Participants in the placebo group take placebo tablets twice a day. Placebo tablets look like BI 1015550 tablets but do not contain any medicine.

Participants are in the study for up to two and a half years. During the first year, they visit the study site 10 times. Afterwards, they visit the study site every 3 months. The doctors regularly test participants' lung function. The results of the lung function tests are compared between the groups. The doctors also regularly check participants' health and take note of any unwanted effects.

Treatment and study plan

BI 1015550

Drug

Participants received film-coated nerandomilast tablets orally twice daily at doses of either 9 mg or 18 mg, with each dose administered at least 12 hours apart and taken with 250 mL of water.

Other names: Nerandomilast, JASCAYD®

Placebo

Drug

Participants received placebo matching 9 mg or 18 mg nerandomilast film-coated tablets orally twice daily, with doses given at least 12 hours apart and each taken with 250 mL of water.

Primary outcomes

  1. Absolute Change From Baseline in Forced Vital Capacity (FVC) [mL] at Week 52

    Time frame: The MMRM model is a longitudinal analysis, and it incorporated FVC measurements from baseline (Week -8 to Week -1) and Week 2, Week 6, Week 12, Week 18, Week 26, Week 36, Week 44 and Week 52. The data represent the Least Squares Mean at Week 52

    The absolute change from baseline in Forced Vital Capacity (FVC) [mL] at Week 52 is reported.

    The absolute change from baseline in forced vital capacity (FVC) at Week 52 was analyzed using a restricted maximum likelihood (REML)-based mixed model with repeated measures (MMRM). The model included fixed categorical effects of treatment and baseline antifibrotic use at each visit, as well as the continuous effect of baseline FVC. Visit was treated as a repeated measure, with an unstructured covariance structure for within-patient variability.

Secondary outcomes

  1. Key Secondary Endpoint: Time to the First Occurrence of Any of the Components of the Composite Endpoint: Time to First Acute IPF Exacerbation, First Hospitalization for Respiratory Cause, or Death (Whichever Occurs First) Over the Duration of the Trial

    Time frame: From first administration of any trial drug (Nerandomilast or Placebo) up to 22.9 months.

    Time to the first occurrence of any component of the composite endpoint-acute IPF exacerbation, hospitalization for a respiratory cause, or death (whichever occurred first)-is reported as the number of participants who experienced one or more of these events during the trial.

    Acute IPF is defined as an acute, clinically significant respiratory deterioration characterized by evidence of new, widespread alveolar abnormality, with all of the following:

    Acute worsening or development of dyspnea, typically of less than 1 month's duration.

    Computed tomography showing new bilateral ground-glass opacity and/or consolidation superimposed on a background pattern consistent with IPF.

    Deterioration not fully explained by cardiac failure or fluid overload.

    If more than one component occurred on the same day, the patient was counted under the first event according to the following hierarchy: acute IPF exacerbation, hospitalization, death.

  2. Time to First Acute IPF Exacerbation or Death Over the Duration of the Trial

    Time frame: From first administration of any trial drug (Nerandomilast or Placebo) up to 22.9 months.

    The time to first acute IPF exacerbation or death during the trial is reported as the number of participants who experienced either event.

    Acute IPF is defined as an acute, clinically significant respiratory deterioration characterized by evidence of new, widespread alveolar abnormality, with all of the following:

    Acute worsening or development of dyspnea, typically of less than 1 month's duration.

    Computed tomography showing new bilateral ground-glass opacity and/or consolidation superimposed on a background pattern consistent with IPF.

    Deterioration not fully explained by cardiac failure or fluid overload.

    If more than one component occurred on the same day, the patient was counted under the first event according to the following hierarchy: acute IPF exacerbation followed by death.

  3. Time to Hospitalization for Respiratory Cause or Death Over the Duration of the Trial

    Time frame: From first administration of any trial drug (Nerandomilast or Placebo) up to 22.9 months.

    Time to hospitalization for respiratory cause or death over the duration of the trial is reported as the number of participants who experienced either event.

    Hospitalizations due to respiratory causes were recorded on a specific non-elective hospitalization CRF page. This page captured the hospitalization date, confirmation of a respiratory cause, and the primary admission diagnosis.

    If more than one component occurred on the same day, the patient was counted under the first event according to the hierarchy: hospitalization for respiratory cause, followed by death.

  4. Time to Absolute Decline in Forced Vital Capacity (FVC) % Predicted of >10% From Baseline or Death Over the Duration of the Trial

    Time frame: From first administration of any trial drug (Nerandomilast or Placebo) up to 22.9 months.

    The time to absolute decline of more than 10% from baseline in forced vital capacity (FVC) percent predicted, or death, over the duration of the trial is reported as the number of participants who experienced either event.

    If more than one component occurred on the same day, the patient was counted under the first event according to the hierarchy; Absolute decline in FVC % predicted of > 10% followed by death.

  5. Time to Absolute Decline in Diffusing Capacity of the Lungs for Carbon Monoxide (DLCO) Percentage Predicted by More Than 15% From Baseline or Death, Measured Over the Duration of the Trial

    Time frame: From first administration of any trial drug (Nerandomilast or Placebo) up to 22.9 months.

    The time to absolute decline of more than 15% from baseline in diffusing capacity of the lungs for carbon monoxide (DLCO) percent predicted, or death, over the duration of the trial is reported as the number of participants who experienced either event.

    Predicted DLCO value was corrected for hemoglobin (Hb).

  6. Time to Death Over the Duration of the Trial

    Time frame: From first administration of any trial drug (Nerandomilast or Placebo) up to 22.9 months.

    Time to death over the duration of the trial is reported as the number of participants who died.

    Time to death will be based either on the date of death on the AE report for patients with AEs leading to death or will be based on the information from the vital status assessment.

  7. Absolute Change From Baseline in Living With Pulmonary Fibrosis (L-PF) Symptoms Dyspnea Domain Score at Week 52

    Time frame: The MMRM model is a longitudinal analysis and it incorporated L-PF measurements from baseline (Week -8 to Week -1) and Week 12, Week 26, Week 36, Week 44 and Week 52. The data represent the Least Squares Mean at Week 52.
