Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with relapsed/refractory multiple myeloma receiving bispecific antibodies and exhibiting hypogammaglobulinemia.

Probably not a fit

Patients with recent major infections, certain viral infections, or those undergoing specific therapies like CAR-T may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of IgPro20 in preventing infections in individuals diagnosed with multiple myeloma who also have hypogammaglobulinemia. Participants will be those receiving bispecific monoclonal antibodies and will have undergone a specific number of treatment cycles. The study aims to determine if IgPro20 can enhance the immune response and reduce infection rates in this vulnerable population.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce infection rates in patients with multiple myeloma and low immunoglobulin levels.

How similar studies have gone: Other studies have explored similar immunoglobulin therapies, showing promise in infection prevention, but this specific approach with IgPro20 is novel.
