New drug cocktail aims to tackle tough lymphoma

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with relapsed or refractory non-GCB DLBCL. * Have at least one measurable lesion according to the Lugano Response Criteria 2014. * ECOG performance status 0-2 (0-1 for dose escalation part). * Life expectancy ≥ 12 weeks. * Adequate coagulation function, liver and kidney function, bone marrow hematopoietic function. * No plan for autologous/allogeneic hematopoietic stem cell transplantation or chimeric antigen receptor T-cell (CAR-T) therapy. * Toxicities from prior anti-tumor therapy have recovered to Grade ≤1 according to NCI CTCAE v5.0. * All male subjects and female subjects of childbearing potential must strictly use medically approved contraception throughout the entire study period. All male subjects must also avoid sperm donation during the above period. For women of childbearing potential, the result of serum pregnancy test must be obtained. Women must be non-lactating * Subjects must provide adequate tissue and blood samples for exploratory study. Participation is voluntary, requiring signed informed consent and compliance with the treatment regimen and visit schedule. Exclusion Criteria: * Intolerance to Rocbrutinib or any drug in the combination regimen. * Prior treatment with a BTK-targeted therapy; prior treatment with R-GemOx. * DLBCL transformed from an indolent lymphoma; diagnosis of high-grade or double-hit DLBCL. * Chemotherapy, biologic therapy (except CAR-T), immunotherapy or major surgery within 4 weeks of the first dose of study treatment. * Small molecule targeted therapy within 4 weeks or within 5 half-lives (whichever is shorter) of the first dose of study treatment. * Herbal or proprietary Chinese medicines with antitumor activity or radiotherapy with a limited field of radiation within 7 days of the first dose of study treatment. * History of allogeneic hematopoietic stem-cell transplantation (allo-HSCT) or other organ transplantation, or autologous HSCT (auto-HSCT) or chimeric antigen receptor T-cell (CAR-T) therapy within 90 days of the first dose of study treatment. * Current corticosteroid therapy at a dose \>20 mg/day prednisone equivalent. The prednisone-equivalent dose must have been stable for at least 4 weeks before Cycle 1 Day 1. * Unable to discontinue prohibited medications during the study period (strong or moderate CYP3A inhibitors or inducers, P-gp inhibitors, OATP1B3-sensitive substrates, warfarin or other vitamin K antagonists). * Known or suspected CNS involvement by lymphoma. * Presence of peripheral neuropathy \> Grade 1. * Any severe and/or uncontrolled systemic disease, or condition affecting drug swallowing or absorption, that in the investigator's judgment makes the subject unsuitable for the study.
