Ig PRx in AECOPD: Pilot Study
- Conditions
- Chronic Obstructive Pulmonary Disease
- Interventions
- Drug: Intravenous immunoglobulin (IVIG)Drug: Normal Saline
- Registration Number
- NCT02690038
- Lead Sponsor
- Ottawa Hospital Research Institute
- Brief Summary
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.

- Arm && Interventions
Group Intervention Description Intervention Arm 1: Treatment Intravenous immunoglobulin (IVIG) Baseline Ig \< 7g/L group - Intravenous immunoglobulin (IVIG) 0.8 g/kg will be given within 12 hours after randomization during hospital admission and then every 4 weeks for 44 weeks (total 48 weeks). Baseline Ig \> or = 7 g/L group - Intravenous immunoglobulin (IVIG) 0.5 g/kg will be given within 12 hours after randomization during hospital admission and then every 4 weeks for 44 weeks (total 48 weeks). Intervention Arm 2: Control Normal Saline Baseline Ig \< 7g/L group - Normal Saline (0.9% NaCl) 8 mL/kg will be given within 12 hours after randomization during hospital admission and then every 4 weeks for 44 weeks (total 48 weeks). Baseline Ig \> or = 7 g/L group - Normal Saline (0.9% NaCl) 5 mL/kg will be given within 12 hours after randomization during hospital admission and then every 4 weeks for 44 weeks (total 48 weeks).
- Primary Outcome Measures
Name Time Method Recruitment 52 weeks Average number of patients being recruited per month. The study meets primary outcome if at least 4 patients can be recruited per month on average.
Adherence and protocol compliance 104 weeks Number and percentage of recruited patients adhere to the allocated treatment and protocol. We aim to achieve 80% adherence rate which is defined as at least 80% of patients adhere to 80% of allocated treatment and protocol
- Secondary Outcome Measures
Name Time Method Number of participants with treatment-related adverse events as assessed by CTCAE 104 weeks This will be assessed by documentation of adverse events in patients treated with Ig treatment versus control
Tolerability of treatment 104 weeks The proportion of patients able to complete the treatment in the experimental arm during the study period versus in the control arm
Efficacy trend: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) rates 104 weeks AECOPD will be ascertained by monthly follow-up phone calls as well as questionnaires during study visits to detect inpatient/outpatient treatment for exacerbations.
Efficacy trend: Health status 104 weeks measured by the validated St. George Respiratory Questionnaire
Efficacy trend: % predicted FEV1 104 weeks FEV1 value will be measured using a hand held spirometer. FEV1 value will be recorded in Litres (L) and reported as a percent of their predicted value (using the NHANES III reference standards for predicted values
Efficacy trend: FEV1/FVC 104 weeks FVC will be measured using a hand held spirometer, and will be recorded in Litres (L). Ratio of FEV1 and FVC will be reported.
Efficacy trend: Health services use 104 weeks Number of non-study physician visits, emergency department (ED) and hospital admissions over the twelve-month study period.
Efficacy trend: Quality of life 104 weeks validated quality of life measurement tool - EuroWol EQ-5D-5L
Efficacy trend: Health care system cost 104 weeks we will take the perspective of healthcare system and will measure the cost of health services use and an intervention. Intervention cost includes medication, staff, and equipment cost.
