Details and patient eligibility

About

This study will look at immunoglobulin (Ig) treatment in hospitalized chronic obstructive lung disease (COPD) patients with frequent exacerbations.

This is a Phase II, pilot randomized double blind control study, meaning this study will help assess if this research can be expanded to evaluate Ig treatment in patients with COPD. Ig treatment is a sterile solution of human immunoglobulin proteins given intravenously (in the vein). Immunoglobulins are part of the immune system and help the body fight infections. Participants will be assigned to either receiving the Ig treatment or normal saline as a control product every 4 weeks for 12 months.

Participants will continue on current standard therapy as determined by their treating physician.

Inclusion criteria

  • Hospitalized adult patient with AECOPD (clinically dominant AECOPD in the case of multiple co-morbidities eg. absence of overt lobar pneumonia or acute congestive heart failure or alternate diagnosis such as acute coronary syndrome or pulmonary embolism)
  • Diagnosis of severe COPD (post bronchodilator FEV1 <50%, FEV1/FVC ratio <0.7) made by standard spirometry within previous 12 months or within three days of admission if previous PFT data is not available
  • Age >40 years
  • >10 pack year smoking history
  • At least one COPD exacerbation in the previous 12 months before enrollment, defined by having had documented inpatient or outpatient treatment by physician with antibiotics and/or prednisone for physician diagnosed COPD exacerbation
  • Expected to live > 12 months

Exclusion criteria
