A Phase I Study of Pembrolizumab Immunotherapy and Umbralisib in Patients with Advanced B-Cell Non-Hodgkin Lymphoma


Full Title

A Phase I, Open-label, Dose-escalation Study to Assess the Safety, Tolerability and Efficacy of the combination of Pembrolizumab with Umbralisib (TGR-1202) in patients with relapsed/refractory CLL and B-Cell Non-Hodgkin Lymphoma (NHL)


The purpose of this study is to find the highest dose of the drug umbralisib (TGR-1202) that can be given safely with pembrolizumab immunotherapy in patients with B-cell non-Hodgkin lymphoma (NHL) that came back or continued to grow despite prior treatment.

Umbralisib blocks an enzyme in some white blood cells called PI3K. In many B-cell cancers, PI3K triggers cancer cells to develop and helps them survive. Blocking PI3K may therefore slow the spread of B-cell NHL. Pembrolizumab works by blocking a protein that cancer cells use to evade detection by the immune system, thereby boosting the ability of the immune system to find and destroy cancer cells.

The use of umbralisib and pembrolizumab together to treat B-cell NHL is considered investigational. Umbralisib is taken orally (by mouth) and pembrolizumab is given intravenously (by vein).


To be eligible for this study, patients must meet several criteria, including but not limited to the following:

  • Patients must have B-cell NHL that came back or continued to grow despite treatment and cannot be successfully treated with existing therapies.
  • Patients should recover from the serious side effects of previous treatments before entering the study.
  • Patients must be physically well enough that they are fully ambulatory, capable of all self care, and are capable of all but physically strenuous activities. As an example, patients must be well enough that they would be able to carry out office work or light housework.
  • This study is for patients age 18 and older.
