Brief Summary
Apoptosis is a specific form of cell death that leads to clearance of dead cells without causing inflammation or injury to normal adjacent tissues. Targeted cancer therapeutics that target this pathway for tumor cell death induction are in development, but few specific biomarkers of apoptosis are available to assess treatment response. Apoptosis also occurs in response to standard anthracycline or combination therapies such as rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP), rituximab, etoposide, phosphate, prednisone, vincristine sulfacte, cyclophosphamide, and doxorubicin hydrocholoride (R-EPOCH) used to treat many different histopathological types of lymphoma including Hodgkin and non- Hodgkin lymphoma such as diffuse large B-cell lymphoma (DLBCL), Burkitts lymphoma, primary mediastinal B-cell lymphoma and double hit DLBCL. Caspase-3 activation occurs as a result of apoptosis and may be a specific marker of apoptosis. Therefore, this study will assess whether 18F-FluorApoTrace (18F-FAT), a caspase-3 targeted tracer, has a reasonable dosimetry profile and can be used to detect apoptosis in patients with lymphoma being treated with standard therapy.

Outcome Measures
Primary Outcomes (4)
Whole body effective dose (in rems) of a 5 mCi injection of 18F-FAT (Cohort 1 only)
-The time activity curves will be created using all the scans obtained and integrated to determine organ residence times. This data, plus the counts and volumes from urine collection(s) after tracer injection, will then be used to calculate the dosimetry using OLINDA/EXM v1.1. The calculated residence times will be used with the program OLINDA/EXM for 18F and using the adult human (adult female or male) model to calculate the whole body effective dose.
Day 1
Radiation doses (rems) to critical organs (Cohort 1 only)
The time activity curves will be created using all the scans obtained and integrated to determine organ residence times. This data, plus the counts and volumes from urine collection(s) after tracer injection, will then be used to calculate the dosimetry using OLINDA/EXM v1.1. The calculated residence times will be used with the program OLINDA/EXM for 18F and using the adult human (adult female or male) model to calculate the individual organ radiation dose.
Day 1
Change in mean standard uptake value (SUV) (Cohort 2 only)
-30 minutes and 60-90 minutes post pre-treatment baseline monitoring scan and 30 minutes and 60-90 minutes post early interim treatment monitoring scan
Through completion of early interim treatment monitoring scan (estimated to be 14 days)
Change in maximum standard uptake value (SUV) (Cohort 2 only)
-30 minutes and 6-90 minutes post pre-treatment baseline monitoring scan and 30 minutes and 60-90 minutes post early interim treatment monitoring scan
Through completion of early interim treatment monitoring scan (estimated to be 14 days)
Secondary Outcomes (2)
Distribution volume ratio (DVR) (Cohort 2 only)
Through completion of early interim treatment monitoring scan (estimated to be 14 days)
Change in percent positive caspase-3 staining (Cohort 2 only)
Baseline and post-treatment (estimated to be 14 days)
Study Arms (3)
Cohort 1 = Healthy Volunteers
EXPERIMENTAL* Healthy volunteers (N=6, three male, three female) will be recruited to undergo a single 18F-FAT PET/CT imaging session for radiation dosimetry estimates. * 18F-FAT administration followed by body imaging at 3 time points * 0-60 min = multiple quick body scans * 120 min post injection = body scan * 240 min post injection = body scan
Cohort 2a: Newly Diagnosed DLBCL patients being treated with R-CHOP
EXPERIMENTAL-N= 6 : 18F-FAT imaging session at baseline and Day 2-4 following Cycle 1 standard of care therapy.
Cohort 2b: Newly Diagnosed DLBCL patients being treated with R-CHOP
EXPERIMENTAL-N=9: 18F-FAT imaging session at baseline and best time point determined from Cohort 2a (2 days post Cycle 1 standard of care therapy)
Interventions
-The dose of 18F-FluorApoTrace to be given is 5 mCi
