A Study of Circulating Tumor DNA (ctDNA) Testing for People With B-Cell Lymphoma

Active systemic therapy for another malignancy (other than indolent B-cell lymphoma) within 2 years; local/regional therapy with curative intent such as surgical resection or localized radiation within 2 years of treatment is permitted.

Active concurrent malignancy with the exception of basal cell or localized squamous cell skin carcinoma, localized prostate cancer, or other localized carcinomas such as carcinoma in situ of cervix, breast, or bladder.

Any uncontrolled illness that in the opinion of the investigator would preclude administration of curative intent chemoimmunotherapy (e.g. significant active infections, hypertension, angina, arrhythmias, pulmonary disease, or autoimmune dysfunction).

Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) at study enrollment, or any major episode of infection requiring treatment with IV antibiotics or hospitalization within 2 weeks prior to Cycle 1, Day 1.
