Clinical Trial Summary

The overarching goals of this study are to measure levels of circulating tumor DNA (ctDNA) in patients with early stage diffuse large B cell lymphoma (DLBCL), to assess the change in ctDNA during treatment in order to prospectively identify markers of treatment failure, and to use ctDNA as a future tool for response adapted therapy.

Description:

The long-term objective of this proposal is to determine the correlation between FDG-PET and MRD, as measured by ctDNA in patients with early stage DLBLC.

Patients will be treated with standard chemoimmunotherapy and radiation based on the recently completed SWOG S1001 study, however no radioimmunotherapy will be used (NCT01359592). Response to treatment will be determined by contemporary Deauville criteria. Assessment of ctDNA (non-invasive disease monitoring) will be determined at diagnosis and will continue at pre-defined specific time points after therapy is complete.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Correlation between fluorodeoxyglucose positron emission tomography (FDG-PET) and MRD, as measured by circulating tumor plasma DNA (ctDNA) in patients with early stage diffuse large B cell lymphoma (DLBCL).		5 years
Secondary	PET CR rate		5 years
Secondary	Change in minimal residual disease (MRD) from baseline to time of re-staging PET		5 years
Secondary	Re-staging Deauville score of 1, 2, or 3 (negative PET scan)		5 years
Secondary	Following 3 cycles of R-CHOP, if PET scan demonstrates complete response, defined by Deauville score of 1, 2, or 3 (negative PET scan), radiation therapy will not be required moving forward		5 years
Secondary	Toxicity rates using CTCAE v4.03		5 years
Secondary	Changes in quality of life using PROMIS scale 10 scale will be administered to patients at the time of diagnosis, at the conclusion of all therapy, and at 12 month intervals		5 years
Secondary	Overall survival (OS) of patients through two years of follow-up.		Patients will be assessed by physical exam and routine bloodwork every 3 months in the 1st year after conclusion of treatment, and every 6 months in the second year following treatment. They will be assessed yearly during years 3, 4 and 5.
Secondary	Progression free survival (PFS)		From time of baseline scan through two years of follow-up
