Relapsed or Refractory B-Cell Non-Hodgkin Lymphoma

Researchers are looking for new ways to treat people with relapsed or refractory B-Cell Non-Hodgkin Lymphoma (B-NHL). B-cells are a type of white blood cells that make antibodies and help fight infections. Non-Hodgkin Lymphoma is a type of cancer in the lymphatic system causing enlarged lymph nodes and/or organs in belly or chest. Relapsed means a disease or condition comes back after treatment Refractory means a disease does not respond to treatment or stops responding to a treatment. MK-1045, the study medicine, is designed to treat relapsed or refractory B-NHL. MK-1045 is an immunotherapy, which is a treatment that helps the immune system fight cancer. This is the first study in which MK-1045 will be given to people. The goal of this study is to learn about: * The safety of MK-1045 and how well people tolerate it. * The highest dose of MK-1045 that is well tolerated. * How well MK-1045 works to treat relapsed or refractory B-NHL.

The purpose of the study is to evaluate the safety、tolerability and preliminary efficacy of B019 in subjects with relapsed or refractory B-cell non-Hodgkin's lymphoma.

This is a Phase 1b/2 study to evaluate the safety and efficacy of autologous T cells engineered with a chimeric antigen receptor (CAR) targeting cluster of differentiation (CD)19 in pediatric patients with relapsed or refractory (r/r) B cell acute lymphoblastic leukemia (B ALL) and r/r B cell Non-Hodgkin lymphoma (B NHL).

This study aims to provide a basis for further clinical development of YK012.

The purpose of this clinical trial is to learn if the study drug pemigatinib is effective in treating patients with relapsed or refractory B-cell non-Hodgkin lymphomas.
