IVIg-related adverse events
Any adverse event occurring at the time of infusion will be observed and described by the study coordinator in attendance during the infusion. Any other event potentially related to the infusion will be discussed with the participant and the principle investigator
Generally, IVIg infusions are well tolerated and the most frequent adverse events that include headache, fever and nausea occur in less than 5% of patients. Anaphylaxis is extremely rare.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A computerised schedule will be generated prior to trial commencement. The randomisation schedule will be used to prepare opaque sealed envelopes containing the unique patient identification number and the group to which they are assigned.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be stratified according to the presence of significant hypogammaglobulinemia (<5g/dL) measured pre-transplant, in the absence of IVIg replacement. Each of these groups will be further stratified according to pre-LTx sensitisation status, as defined by the most recent pre-transplant presence of anti-HLA donor specific antibodies. Patients will fall into 1 of 4 groups. A computerised randomisation schedule will be independently generated for each group.

Statistical methods / analysis
The statistical analyses will be mainly descriptive using an intention-to-treat framework including all eligible randomized patients.
As the end-point of time to develop of a composite of i) death with a failing graft, ii) re-transplantation and iii) CLAD (censored at the end of follow-up) forms the basis of the sample size calculation for a future definitive efficacy RCT comparisons between both arms will be made using Cox proportional hazards model with treatment allocation as the only dependent variable.

Summary
Brief summary
Intravenous immunoglobulin (IVIg) (a type of antibody) is given after lung transplantation to correct low levels in the blood of individuals. It is safe and thought to help reduce infection and rejection after transplant. This is a pilot randomised clinical trial which compares routine IVIg therapy with placebo in patients following lung transplant. Participants will be randomised in a 1 to 1 manner to receive either IVIg or placebo (Human Albumin) at week 6 post transplant and thereafter monthly for 6 months.
Each participant will be followed for 1 year following transplant. Evidence of recruitment and retainment will be collected. Additionally, details of all episodes of infection, rejection, and hospitalisation will be collected. Adverse events related to the study drug and IgG levels will be collected for safety analysis.
