Clonal Hematopoiesis of Indeterminate PotentialNCT06870760
Pre-malignant States to Hematologic Malignancies in Firefighters
An observational study of Clonal Hematopoiesis of Indeterminate Potential and Monoclonal Gammopathy, run by Wake Forest University Health Sciences at 1 site in United States.
Trial summary
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.

About this study
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.
Read the detailed description
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

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Monoclonal GammopathyOther
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)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)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.
| Study group | Role | What they receive |
|---|---|---|
| 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 Receives: Other: Monoclonal Gammopathy; Other: Complete Blood Count with differential (CBC w/ diff); Other: Clonal hematopoiesis (CHIP) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Clonal Hematopoiesis (CHIP)
The presence of positive somatic mutation will be determined for each enrolled participant as a binary variable indicating if the participant is harboring clonal hematopoiesis.
Measured: From enrollment to availability of lab results, approximately 6 months
Secondary outcomes (3)
Monoclonal Gammopathy (MGUS)
The presence of monoclonal gammopathy will be determined for each enrolled participant as a binary variable defined as abnormal SPEP, IFE, or FLC result.
Measured: From enrollment to availability of lab results, approximately 1 week
Targeted Diagnoses Rate
The presence of a diagnosis(es) based off standard of care diagnostic assessment(s) will be determined for each enrolled participant and for each diagnosis. Targeted diagnoses: MGUS, Smoldering Multiple Myeloma, Multiple Myeloma, AL Amyloidosis, Other Plasma Cell Disorder, Myelodysplastic Syndrome (MDS), Acute Myeloid Leukemia (AML), Aplastic anemia, Clonal cytopenia of undetermined Significance (CCUS), and Other.
Measured: up to 12 months after all labs have resulted
Baseline Survey Results
Baseline survey results will be summarized descriptively. The survey is an 18-item survey collecting data including: demographic information, personal and family health history, social behaviors, firefighting experience, prior history of cancer and other items related to firefighting experience. The survey question responses will be collected as either quantitative responses, nominal categorical responses, or ordered categorical responses.
Measured: Baseline

What does the primary outcome measure?
Clonal Hematopoiesis (CHIP) (time frame: From enrollment to availability of lab results, approximately 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2026.
