A Phase I Study of PSB202 in People with Recurrent or Persistent Indolent B-Cell Lymphoma


Full Title

A Phase 1a/1b Study of PSB202 in Patients with Previously Treated, Relapsed, Indolent B-Cell Malignancies


The purpose of this study is to find the highest dose of the investigational drug PSB202 that can be given safely in people with indolent B-cell lymphoma that has come back or continued to grow despite treatment. PSB202 blocks the activity of proteins that contribute to cancer cell growth. By blocking these proteins, it may stop the growth of B-cell lymphomas. PSB202 is given intravenously (by vein).

  • Patients’ cancers must make the CD20 protein (the targets of the drugs used in this study).
  • At least 4 weeks must pass between the completion of previous treatments and receipt of the study therapy.
