A Multicenter Study PRECISE-HL: Personalized Reduction of Chemotherapy Intensity Through ctDNA Evaluation in Advanced Hodgkin Lymphoma
University of Washington
Summary
This phase II trial tests how well personalized reduction of chemotherapy (nivolumab, doxorubicin, vinblastine and dacarbazine) based on circulating tumor deoxyribonucleic acid (ctDNA) evaluation works for treating patients with Hodgkin lymphoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Chemotherapy drugs, such as nivolumab, doxorubicin, vinblastine and dacarbazine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Many types of tumors tend to lose cells or release different types of cellular products including their DNA, which is referred to as ctDNA, into the bloodstream before changes can be seen on scans. Health care providers can measure the level of ctDNA in blood or other bodily fluids and, based on the result, assign patients to a reduced number of chemotherapy treatments or the standard number of chemotherapy treatments. Using ctDNA to assign a personalized reduction of chemotherapy may be effective in treating patients with advanced Hodgkin lymphoma.
Description
OUTLINE: CYCLES 1-2: Patients receive nivolumab intravenously (IV), doxorubicin IV, vinblastine IV and dacarbazine IV on days 1 and 15 of each cycle. Cycles repeat every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Patients then undergo measurable residual disease (MRD) testing. Patients who are MRD negative are assigned to Arm I and patients who are MRD positive are assigned to Arm II. ARM I: CYCLES 3-4: Patients receive nivolumab IV, doxorubicin IV, vinblastine IV and dacarbazine IV on days 1 and 15 of each cycle. Cycles repeat every 28 days…
