Phase 2 Study of Polatuzumab Vedotin, Rituximab and Dose Attenuated CHP in Older Patients With DLBCL
Phase 2 Study of Polatuzumab Vedotin, Rituximab and Dose Attenuated CHP in Older Patients With DLBCL
The purpose of this study is to test the effectiveness and safety of polatuzumab vedotin in combination with R-miniCHP in patients 75 years and older with DLBCL.
In this study, the investigator would like to better understand the efficacy and safety of the addition of polatuzumab vedotin to therapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) and dose attenuated R-CHOP in patients who are aged 75 years and older.
Inclusion Criteria:
Voluntary written informed consent before performance of any study-specific procedure not part of routine medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care. Subjects must be able to understand and be willing to sign the written informed consent form.
Men and women aged greater than or equal to 75 years of age
ECOG performance status of 0-3

Has received no prior therapy for aggressive B-cell lymphoma or HT with the following exceptions:
Patient is not felt to be a candidate for standard dose R-CHOP due to age or comorbidities, per the site investigator.
Ejection fraction of ≥ 45% on echocardiogram or MUGA
Patient has a platelet count of ≥75,000/μL within 14 days before enrollment unless inadequate function is due to bone marrow infiltration with aggressive B-cell lymphoma
Patient has an absolute neutrophil count of ≥1,500/ μL within 14 days before enrollment unless inadequate function is due to bone marrow infiltration with aggressive B-cell lymphoma
Patient has a calculated or measured creatinine clearance of >30 mL/minute within 14 days before enrollment.
Total bilirubin must be less than 1.5 times the upper limit of normal (ULN) unless the elevation is known to be due to Gilbert syndrome or hepatic involvement with aggressive B-cell lymphoma in which case it can be ≤ 3.0 times the ULN.
ALT or AST must be ≤ 2.5 times the ULN.

Exclusion Criteria:
History of, or clinically apparent central nervous system (CNS) lymphoma

Patient is known to be HIV positive (test result not required for enrollment).
Patient has active hepatitis B with a positive surface antigen or viral load. Carriers of hepatitis B virus should be closely monitored for clinical and laboratory signs of active HBV infection and for signs of hepatitis throughout study participation according to national and local guidelines.
