Hypogammaglobulinemia study: Xembify
Official title A Study to Evaluate Efficacy, Safety, and PK of XEMBIFY®+Standard Medical Treatment (SMT) Compared to Placebo+SMT to Prevent Infections in Participants With HGG and Recurrent or Severe Infections Associated With B-cell Chronic Lymphocytic Leukemia, Multiple Myeloma, and Non-Hodgkin Lymphoma
ClinicalTrials.gov ID: NCT05645107
What this study is testing
What is Xembify?
This is an investigational medicine being studied to help lower the chance of serious bacterial infections in people with low antibody levels. It is designed to provide your body with antibodies to help fight off infections.
Also referred to as Immune Globulin Subcutaneous (Human), 20%.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study aims to find out if taking XEMBIFY every two weeks reduces the number of major bacterial infections compared to a placebo.
- Who it's for
- The study is looking for adults with B-cell chronic lymphocytic leukemia, multiple myeloma, or non-Hodgkin lymphoma who have low antibody levels and a history of recurrent or severe infections.
- What's involved
- Participants will receive either the study medicine or a placebo along with their usual medical care. They will also undergo regular tests to check safety and how the body handles the drug.
- Time commitment
- The study lasts for one year and requires regular visits to receive treatment and complete safety checks.
- Phase 3: a large, late-stage study
- You might receive a placebo (an inactive treatment) instead of the study drug.
