About this trial

Acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF) are sudden and severe worsening episodes that can be life-threatening. Currently, no treatment has been proven to clearly improve outcomes during these events. Inflammation and immune system imbalance are thought to play an important role in causing AE-IPF. Early clinical experience suggests that intravenous immunoglobulin (IVIG) can be beneficial for patients suffering from AE-IPF. This clinical trial aims to determine whether adding IVIG to usual treatment can improve outcomes for patients hospitalized with AE-IPF.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients ≥ 18 years of age

Patients with IPF diagnosis that fulfils ATS/ERS Consensus Criteria.

Patients hospitalised with a definite or suspected AE-IPF diagnosis, as defined by the international working group criteria and as ascertained by the responsible Primary Investigator.

Previous or concurrent diagnosis of IPF

Disqualifiers

Patients with acute worsening due to uncontrolled heart failure or pulmonary embolism.

Patients with known hypersensitivity to corticosteroids, IVIG or any component of the study treatment.

Patients with known IgA deficiency (IgA level <7 mg/dL)- to preclude IVIG reactions.

Patients without a definite diagnosis of IPF or AE-IPF based on clinical, radiological, laboratory evaluation, and multidisciplinary discussion.

Treatments tested in this trial

  • Intravenous immunoglobulin (IVIG)

    Drug

    Total dose of 1 g/kg, divided over three consecutive days. The infusion will start at a rate of 0.5 mg/kg/hour for the first 15 minutes and, if no adverse reaction occurs, the rate will then be gradually increased step-wise as tolerated. Premedication with acetaminophen and levocetirizine. Usual treatment will be co-administered, as described.

  • Usual treatment

    Drug

    1. Corticosteroids: A pulse regimen of IV methylprednisolone at 250 mg daily (days 1 to 3), with no additional corticosteroids thereafter. 2. Antibiotics: Empirical broad-spectrum antibiotics starting from the first 24 hours of hospitalization - respiratory quinolone and/or an antipseudomonal penicillin. Duration or escalation of antibiotics may be adjusted based on available antibiograms or treating physician's clinical judgment. 3. Anticoagulation: Prophylactic-dose anticoagulation - low molecular weight heparin or fondaparinux - throughout hospitalization. Patients with an established indication for therapeutic anticoagulation will be maintained on their therapeutic regimen. 4. Antifibrotic therapy: Antifibrotics (nintedanib, pirfenidone, or nerandomilast) will be continued during hospitalization if already prescribed and not contraindicated. No new antifibrotic treatment will be initiated during the study period.

Secondary outcomes

1

All-cause 30-day mortality

This outcome corresponds to all-cause mortality rate at Day 30

Time frame
30 days from hospital admission
2

All-cause 90-day mortality

This outcome corresponds to all-cause mortality rate at Day 90

Time frame
90 days from hospital admission
3

Hospital readmissions

This outcome corresponds to all-cause hospital readmission rates by Day 180

Time frame
180 days from hospital admission
4

New acute exacerbation IPF

This outcome corresponds to occurence of new acute exacerbation of IPF by Day 180

Time frame
180 days from hospital admission

Other outcomes
