Study of Betalutin for Treatment of Relapsed or Refractory Non-Hodgkin Lymphoma (LYMRIT-37-05)

NCT02658968

Description:

This study is a phase 1, dose finding, open-label study in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). This is a dose escalating study to define the maximum tolerable dose of lutetium (177Lu)-lilotomab satetraxetan (Betalutin®) in DLBCL patients who are not eligible for autologous stem cell transplant. The study will also assess safety and toxicity, pharmacokinetics, biodistribution and efficacy.
