Study Title

An Open-label Dose Escalation Study to Evaluate Safety, Tolerability, Biodistribution and Efficacy of [90Y]Y-PentixaTher for the Therapy of Recurrent or Refractory Primary or Isolated Secondary Central Nervous System Lymphoma.

Study Details

Description:

This will be an open-label, single-arm, national phase 1/2 therapeutic study to evaluate the safety, tolerability, and preliminary efficacy of [90Y]Y-PentixaTher ([90Y]Y-PTT) for the treatment of recurrent or refractory primary or isolated secondary central nervous system (CNS) lymphoma. The study will be performed in three cohorts with different dose levels (2, 4 and 6 GBq) according to the best-of-5 dose escalation design. A safety review committee (SRC) will evaluate dose-limiting toxicities and decide about escalation and de-escalation. Eligible patients will receive one cycle of [90Y]Y-PTT, which will be administered intravenously. There will be no comparator in this study. Safety, biodistribution, dosimetry and efficacy will be evaluated during the core study phase (Visit 1 until Visit 5). Thereafter three follow-up (FU) visits will take place, at three-months intervals to evaluate the extent of disease.
