Screening for M-protein in relatives of multiple myeloma patients in China

The China Monoclonal Gammopathy Screening Project in First-degree Relatives of Patients With Multiple Myeloma (CHAPERONE) --A Multicenter Observational Study

Observational Shanghai Zhongshan Hospital · NCT05965115

This study is trying to see if screening for a specific protein in the blood can help find early signs of a blood condition in family members of people with multiple myeloma in China.

What this trial studies

The CHAPERONE study aims to evaluate the clinical significance of screening for monoclonal gammopathy (M-protein) in first-degree relatives of patients with multiple myeloma in China. It will establish a prospective cohort of individuals with monoclonal gammopathy of undetermined significance (MGUS) and study the prevalence, progression, and influencing factors of this condition. Participants will undergo M-protein screening through serum electrophoresis, and those with detected M-protein will receive further diagnostic assessments and follow-up care.

Who should consider this trial

Good fit: Ideal candidates are first-degree relatives of multiple myeloma patients who are over 18 years old.

Not a fit: Patients with a known diagnosis of plasma cell diseases, such as MGUS or multiple myeloma, will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to early identification and monitoring of individuals at risk for developing multiple myeloma.

How similar studies have performed: Other studies have shown success in screening for monoclonal gammopathy, indicating that this approach has potential benefits.
