Examining immune dysfunction in COPD patients and its treatment

Prevalence of Humoral Immune Deficiency in Patients With Frequent Exacerbations of COPD, and the Effect of Immunoglobulin Replacement on Future Exacerbations

Phase 2 Interventional Rochester General Hospital · NCT05764993

This study is testing if a new immune therapy can help people with COPD who have low antibody levels experience fewer flare-ups of their condition.

What this trial studies

This study investigates the prevalence of humoral immunodeficiency in patients with Chronic Obstructive Pulmonary Disease (COPD) by assessing immunoglobulin levels and vaccine responses. Patients identified with humoral dysfunction will be randomized to receive either Subcutaneous Immune Globulin Replacement Therapy (SCIgR) or standard care management. The aim is to determine if SCIgR can reduce the frequency of acute exacerbations of COPD. The study will involve evaluations at outpatient pulmonary clinics and will include a total of 40 patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 82 with a diagnosis of COPD and a history of frequent exacerbations despite standard therapy.

Not a fit: Patients without humoral dysfunction or those not meeting the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management and reduced exacerbations for COPD patients with humoral dysfunction.

How similar studies have performed: Other studies have shown promise in treating humoral dysfunction in similar patient populations, suggesting potential for success in this approach.
