This phase I trial tests the safety, side effects and best dose of ruxolitinib in combination with cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) chemotherapy and how well the combination works in treating patients with untreated nodal T-follicular helper (TFH) cell lymphoma. Ruxolitinib phosphate blocks a protein called janus kinase, which may help keep abnormal blood cells or cancer cells from growing. It may also lower the body's immune response. Ruxolitinib phosphate is a type of tyrosine kinase inhibitor. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It may also lower the body's immune response. Doxorubicin damages the cell's DNA and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Doxorubicin is a type of anthracycline antitumor antibiotic. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Giving ruxolitinib in combination with CHOP chemotherapy may be safe, tolerable, and/or effective in treating patients with untreated nodal TFH cell lymphoma.
