NCT ID: NCT05678621 Recruiting - Clinical trials for Haematological Malignancy

Role of Antibiotic Therapy or Immunoglobulin On iNfections in hAematoLogy: Immunoglobulin Stopping or Extension

RATIONALISE
Start date: November 30, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

The aim of the study is to find out if patients with blood cancers receiving immunoglobulin (Ig) for the purpose of preventing infections can safety stop immunoglobulin after six months of therapy, and take oral antibiotics instead to prevent serious infections. Patients may be eligible to join this study if they are aged 18 years or above, have an acquired hypogammaglobulinaemia secondary to a haematological malignancy, and have been receiving intravenous or subcutaneous Ig for longer than 6 consecutive months. Participants will be randomised (allocated by chance) to one of three treatment groups, as follows: - Stop immunoglobulin (IVIg or SCIg) and be given oral antibiotics to take every day (ARM A) - Stop immunoglobulin (IVIg or SCIg) and be given oral antibiotics to keep at home to use as soon as symptoms of an infection develop (ARM B) - Continue receiving immunoglobulin (IVIg or SCIg) - this is the usual care group (ARM C) The duration of each treatment is for 12 months from study entry. Participants will be asked to attend a screening/baseline visit so that their treating clinician can assess their eligibility for the trial and collect baseline data. If eligible for the trial, participants will then be randomly allocated to one of the three treatment groups. Once randomised, active participation in the study will last for 13 months. During this period, participants will be asked to return to the hospital for a study visit every 3 months, with monthly telephone visits to check-in on your progress between each in-person visit. Participants will also be asked to complete a study diary, recording treatment compliance and signs/symptoms of infection experienced throughout the study period. Types of assessments and data collected will include: Medical history, demographics, physical examination, blood tests, stool sample, quality of life questionnaires, information about your general health, hospitalisations, medications and procedures. In order to assess and compare the cost-effectiveness of the treatment groups, the study team will also request authorisation from participants to access their Medicare Benefits Schedule (MBS), Pharmaceutical Benefits Scheme (PBS), and Australian Immunisation Register (AIR) data.

NCT ID: NCT05645107 Recruiting - Clinical trials for Bacterial Infections

A Study to Evaluate Efficacy, Safety, and Pharmacokinetics of XEMBIFY® Plus Standard Medical Treatment (SMT) Compared to Placebo Plus SMT to Prevent Infections in Participants With Hypogammaglobulinemia and Recurrent or Severe Infections Associated With B-cell Chronic Lymphocytic Leukemia

Start date: December 26, 2022
Phase: Phase 3
Study type: Interventional

The primary purpose of the study is to evaluate whether weekly administered XEMBIFY® plus Standard Medical Treatment (SMT) over a one-year period will reduce the rate of major bacterial infections per participant per year in participants with hypogammaglobulinemia (HGG) associated with B-cell chronic lymphocytic leukemia (CLL) in comparison to the Placebo plus SMT group.

NCT ID: NCT05357781 Recruiting - Multiple Sclerosis Clinical Trials

Immunoglobulin Deficiency a Treatable Cause of Fatigue in Patients With Multiple Sclerosis (MS)?

FatIgG
Start date: July 1, 2022
Phase:
Study type: Observational

The investigators hypothesize that hypogammaglobulinemia (defined as IgG serum concentration <7.0g/L) is a treatable cause of fatigue in people with MS: The primary objective is to prove the link between hypogammaglobulinemia and fatigue in patients with multiple sclerosis. The secondary objective is to show that fatigue is mediated via frequent infections in people with MS and hypogammaglobulinemia.

NCT ID: NCT04502030 Recruiting - Clinical trials for Chronic Lymphocytic Leukemia

Double-blind, Randomized, Placebo-controlled, Prospective Phase III Study Evaluating Efficacy and Safety of Panzyga in Primary Infection Prophylaxis in Patients With Chronic Lymphocytic Leukemia ("PRO-SID" Study)

Start date: October 5, 2020
Phase: Phase 3
Study type: Interventional

Study Evaluating Efficacy and Safety of Panzyga in Primary Infection Prophylaxis in Patients with Chronic Lymphocytic Leukemia

NCT ID: NCT04283747 Recruiting - Multiple Sclerosis Clinical Trials

Rituximab-Induced Hypogammaglobulinemia in Multiple Sclerosis

Start date: February 28, 2020
Phase:
Study type: Observational

B cells are considered major contributors to multiple sclerosis (MS) pathogenesis, a role that has taken on renewed importance with the advent of B-cell-depleting therapies. Rituximab is being increasingly utilized as an off-label treatment option across MS patients . In addition, there have been increasing reports of rituximab causing hypogammaglobulinaemia and antibody deficiency across a variety of conditions including MS and related neuroinflammatory disorders. Therefore, the purpose of this study is to evaluate the rate of hypogammaglobulinemia in rituximab-treated MS adult patients and to assess the correlation with vaccination response during the treatment.
