NCT06755619

Brief Summary

This is an international, prospective, multicenter trial with the aim of characterizing circulating tumor DNA (ctDNA) for early response assessment in PCNSL patients treated with standard of care (SOC) 1st line therapy with a curative intent (Figure 1). Secondary endpoints are to assess the clinical characteristics, health-related quality of life (HRQoL), neurological status, and outcome of newly diagnosed primary central nervous system lymphoma (PCNSL) patients in the Nordic countries. Patients eligible for a curative intent SOC 1st line therapy, such as MATRix + high-dose chemotherapy and autologous stem cell transplantation (HDCT/ASCT), are eligible for the trial. Diagnostic tumor tissue, cerebrospinal fluid (CSF), and plasma samples are collected for ctDNA and translational analyses with the aim describing new prognostic and predictive biomarkers. Treatment responses are assessed with the International PCNSL Collaborative Group (IPCG) response criteria, and diagnostic and response assessment magnetic resonance imaging (MRI) images are centrally analyzed in order to describe new prognostic and predictive markers.

Study Population

Patients with newly diagnosed primary central nervous system diffuse large B-cell lymphoma

You may qualify if:

  • Age 18-70 years at diagnosis
  • Histologically or cytologically verified diffuse large B-cell lymphoma (DLBCL) of the central nervous system (CNS)
  • No prior treatment for PCNSL (pre-treatment corticosteroids are allowed and recommended)
  • Fit for standard of care (SOC) 1st line therapy with a curative intent such as full-dose MATRix, according to local policy
  • Able to give voluntary written informed consent
  • If the patient is temporarily incapacitated to give the voluntary written informed consent, due to PCNSL, the informed consent can be obtained from a legally acceptable representative, according to the International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use - Guideline for Good Clinical Practice (ICH-GCP) guidelines

You may not qualify if:

  • Lymphoma outside the CNS
  • History of prior hematological malignancy e.g. low grade B-cell lymphoma
  • Psychiatric illness or condition, other than PCNSL, which could interfere with the ability to understand the requirements of the study
