Clinical summary

Summary

This study will be made up of two parts: Part 1 (non-randomised) and Part 2 (randomised - controlled).

The aim of Part 1 of the study is to see how safe and tolerable the study drug is when given alone.

The aim of Part 2 of the study is to see how the study drug works compared to rituximab (called the "comparator drug") and chemotherapy (the current standard of care for Non-Hodgkin Lymphoma). Standard of care means the usual medication expected and used when receiving treatment for a condition.

The study is looking at several other research questions, including:

  • What side effects may happen from taking the study drug
  • How much study drug is in the blood at different times
  • Whether the body makes antibodies against the study drug (which could make the study drug less effective or could lead to side effects)
  • How the study drug affects quality of life and ability to complete routine daily activities.
