About this study
Official title: Role of Antibiotic Therapy or Immunoglobulin On iNfections in hAematoLogy (Stop-Ig)
This study is being conducted to find out how safe and effective different strategies of infection prevention are in comparison to each other, for preventing infection in patients with blood cancers. The best way to find out this information is to directly compare the effect of different treatment strategies in patients with blood cancers. We want to know how these different treatments impact on your health and your use of healthcare services.
This research project uses an Adaptive Platform Design. This design allows the researchers to compare multiple infection prevention strategies within the same trial at the same time (rather than running separate trials), to analyse results as the trial occurs and to add new research questions during the course of the trial.
The treatments that you may receive as part of the study will be determined by which domain(s) of the platform you participate in. By combining data collected within each domain as part of the platform, the researchers can investigate and compare treatment strategies and infection outcomes across a broader range of participants.
Read the detailed description
This is a domain within the RATIONAL Platform Trial to test the effectiveness and safety of stopping Ig replacement with or without prophylactic antibiotics compare to continuing Ig replacement.
- Conditions
- Myeloma, Leukemia, Non Hodgkin's Lymphoma
- Being tested
- Trimethoprim Sulfamethoxazole, Amoxycillin/clavulanic acid, Immune Globulin Intravenous
- Keywords
- immunoglobulin, antibiotics, myeloma, leukaemia, lymphoma, non Hodgkins, infection, infections, blood, cancer, haematology

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Trimethoprim SulfamethoxazoleDrug
Also called Co-Trimoxazole
Once daily trimethoprim-sulfamethoxazole (co-trimoxazole) 160mg/800mg. NB: Doxycycline 100mg daily as an alternative for patients with hypersensitivity to co-trimoxazole.
Amoxycillin/clavulanic acidDrug
Also called Ciprofloxacin
Patients will be provided with amoxycillin/clavulanic acid 1750-2000mg/250mg and ciprofloxacin 750 mg to keep at home for initial use if symptoms of infection develop, with immediate review by their treating clinical team, or nearest emergency department or medical practitioner with phone contact to treating team if most practical.
Immune Globulin IntravenousBiological
Also called Immune Globulin Subcutaneous
Participants will continue treatment with their current Ig replacement schedule. Participants will receive monthly (every 4 weeks ± 1 week) intravenous immunoglobulin at a dose of 0.4g/kg, modified to achieve an IgG trough level of at least lower limit of age-specific serum IgG reference range. For patients who have already had their Ig dose titrated to IgG trough level, they may continue on their current monthly dose of Ig replacement. SCIg, weekly, may be used in patients who meet local criteria for home-based self-administration in centres with established SCIg programs. Dosing is usually given at 100mg/kg/week, modified to achieve an IgG steady state level of at least the lower limit of the serum reference range.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Trimethoprim Sulfamethoxazole, Amoxycillin/clavulanic acid and Immune Globulin Intravenous in people with Myeloma and Leukemia, run by Monash University at 3 sites in Australia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 7 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Event-free survival (EFS). (time frame: 12 months following randomisation (or, in domains with a single treatment arm, time from registration).). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Oct 2025.
