Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to evaluate if firefighter exposure to hazardous compounds will increase the incidence of premalignant hematological states which subsequently increases the risk of the development of hematologic malignancies, and potentially other pathophysiological consequences.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Firefighters from the Charlotte Fire Department, ages 40-49 and with at least 5 years on the job experience will be offered consent for this study. Consented and eligible participants will have labs collected at the Baseline visit to evaluate for CHIP and monoclonal gammopathy. Buccal swabs (also collected at Baseline) and any remaining blood from the Baseline labs will be collected from participants who consent to collection and banking of their samples for future research. Participants will also complete the Firefighter History Assessment at Baseline.

If clonal hematopoiesis (CHIP) results are interpreted by the investigator as abnormal, the participant will be given a clinical referral if indicated for discussion of diagnosis, potential further diagnostic tests, and implications per standard CHIP management guidelines. If monoclonal gammopathy or other (concerning) abnormality of the complete blood count is detected, the participant will be provided a referral for a clinic visit for diagnostic assessments and followed up per standard of care.

If the participant proceeds with the referral and diagnostic work-up, the final diagnosis (if any) resulting from the initial diagnostic assessment(s) will be collected

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Firefighter

Participants employed by the Charlotte Fire Department (CFD) with at least 5 years of on-the-job experience between the ages of 40 and 49

Monoclonal Gammopathy

Intervention Type OTHER

Whole blood will be collected at the Baseline visit to evaluate for monoclonal gammopathy through SPEP, immunofixation, and free light chains.

Complete Blood Count with differential (CBC w/ diff)

Intervention Type OTHER

Whole blood will be collected at the Baseline visit for CBC with differential which may inform a diagnosis of a plasma cell disorder or other hematological disorder.

Clonal hematopoiesis (CHIP)

Intervention Type OTHER

Whole blood will be collected at the Baseline visit to be evaluated using next generation sequencing (NGS) detection of CHIP. Deep NGS to identify mutations associated with myeloid neoplasms and CHIP will be performed using an error-correcting next generation sequencing multi-gene panel targeting genes most frequently mutated in CHIP.
