What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study compares different ways to prevent infections in people with blood cancers like myeloma, leukemia, and lymphoma. About 900 participants will receive either daily antibiotics or immunoglobulin therapy, or a combination. The goal is to see which approach works best to keep patients infection-free and reduce the need for emergency care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Trimethoprim-sulfamethoxazole (co-trimoxazole) or doxycycline, plus amoxicillin/clavulanic acid and ciprofloxacin
What this could lead to
If successful, this could identify the best way to prevent serious infections in people with blood cancers, reducing hospital visits and improving quality of life.
What could go wrong
This is an early-to-mid-stage trial, so results may not apply to all patients. Antibiotics can cause side effects like allergic reactions or resistance, and immunoglobulin may not be better than stopping it.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patients must be receiving Ig (IV or subcutaneous - SCIg) replacement for prevention of bacterial infections due to hypogammaglobulinaemia for at least 6 consecutive months. 2. Patient is eligible for trial of Ig cessation in the opinion of the treating clinician and local investigator. 3. Patient is willing and able to comply with each of the treatment arms. Exclusion Criteria: 1. Prior or planned allogeneic haematopoietic stem cell transplantation. 2. Major infection (Grade 3 or higher) in preceding 3 months, and/or current active infection requiring systemic antimicrobial treatment. 3. Already receiving systemic antibiotic prophylaxis for the purpose of preventing bacterial infection (NB: patients may receive antiviral, antifungal and PJP prophylaxis). 4. Intolerance of all trial antibiotic options in either arm A or arm B. 5. Communication, compliance or logistical issues that are likely to limit patient's ability to take prophylactic or emergency antibiotics, or to obtain urgent medical attention for symptoms of infection. 6. Pregnant or breastfeeding. 7. Severe renal impairment (estimated or measured creatinine clearance of \< 30 mL/min). 8. Previous splenectomy. 9. Previous participation in this domain. 10. Treating team deems enrolment in the domain is not in the best interests of the patient.
